Illinois property tax: value, rates and the bill
A home can have a $300,000 market value and a very different number on the assessment roll. The tax rate belongs to the correct taxable base, not automatically to the sale price. Follow the numbers in order, then separate the assessment year, payment year and tax-lien rules.

The short answer
Property tax is a local tax based on property value, also called an ad valorem tax. In a standard Illinois exam problem, apply the stated assessment level to market value, apply the equalization factor to assessed value, subtract eligible exemptions from equalized assessed value, then multiply taxable EAV by the applicable aggregate rate. Illinois has no single statewide property-tax rate. Local levies, tax bases, legal limits and the districts serving the parcel affect the result.
Reviewed October 27, 2026. Government property taxes and special assessments appear in national II.A.1 of the PSI Illinois broker outline. The whole Land Use Controls domain has five of 100 scored national questions across several subjects, not five on property tax alone. Related calculations and Illinois tax rules can be tested elsewhere. These are original teaching questions, not recalled PSI items or a validated readiness score.
Read the base, the rate and the year before calculating
- Name the value you have. Fair cash value is the market-value concept defined in Section 1-50: a willing buyer and seller in an ordinary transaction without duress. Assessed value, EAV and taxable EAV are later tax calculations. A purchase price can be evidence of value without replacing every assessment rule. If the problem already supplies EAV, do not assess or equalize that number again.
- Apply the relevant assessment method. Most Illinois property uses a one-third assessment level, subject to classification and special statutory methods. Cook County classifies property; ordinary residential and commercial categories commonly use 10% and 25% respectively, with other classifications and incentive rules. Farmland and preferential property need their actual rules. Use the level supplied by a clear exam problem rather than applying one-third to every parcel.
- Apply equalization to the correct assessment. Local and state equalization serve different stages of the system. Multiply the stated assessed value by the stated applicable factor to find EAV. A factor of 1.05 means multiply by 1.05, not by 5 or 0.05. Special property can be outside ordinary state equalization; the simplified chain is not a universal method for every farm, coal or preferential assessment.
- Subtract only the eligible exemption amount. Homestead relief generally reduces EAV before the rate is applied. It is not the same dollar reduction in the tax bill. Eligibility, amount, assessment year, application and renewal depend on the program. Do not subtract an exemption again if the problem already gives taxable EAV. A qualifying senior assessment freeze limits a base EAV; it does not freeze every rate or the entire bill.
- Convert the rate before multiplying. A rate of $6.50 per $100 is 6.5%, or 0.065. One mill is $1 per $1,000, or 0.001; use mills when the problem actually gives that unit. Add individual district rates only when an aggregate rate has not already been supplied. An effective rate using full market value has a different denominator from the aggregate rate applied to taxable EAV.
- Distinguish a levy from a rate. Taxing districts seek specified revenue through their levies. In a simplified problem with no other limits or adjustments, a district’s rate equals its levy divided by its tax base. Actual extension involves legal limits and adjustments. Equalization or higher property values do not by themselves establish a proportional increase in the final tax bill; district rates can change as the base changes.
- Match the task to the official. Assessors value property; review bodies handle assessment issues; IDOR performs state equalization; taxing districts levy; the county clerk handles extension and rates; the collector prepares bills, collects and distributes revenue. This is a division of responsibilities, not a claim that only one official can ever assess or correct a value.
- Keep the years and installments separate. Illinois generally values property for one year and calculates, bills and collects the related tax in the next. A 2025 assessment generally leads to a bill paid in 2026. An installment is not automatically half the current annual bill; under accelerated billing, the first installment uses 55% of the prior year’s bill. Check the actual county notice for due dates and the applicable billing method.
- Identify the real assessment complaint. Value, property-record errors and unequal assessment are different from disagreement with a school levy or the tax rate. Examine the property record and relevant assessment-year evidence. The ordinary formal assessment route begins with a written county board-of-review complaint before a further PTAB appeal or circuit-court tax objection. Applicable notices, local deadlines and procedural requirements matter; receiving a bill can be too late for that year’s assessment appeal. Taxes remain payable while the later appeal is pending.
- Treat the tax lien as a title issue before delinquency. Section 21-75 provides a prior and first lien, including the stated penalties, interest and costs, from January 1 of the year in which the taxes are levied until payment or sale under the Code. Do not change that trigger to the payment deadline or first missed installment. Actual title treatment requires the applicable tax records and law; this lesson does not decide a federal-priority dispute.
- Separate a tax sale from a later tax-deed auction. Current Sections 1-148 and 1-147 distinguish the transfer of a property-tax lien or certificate from the auction that transfers property. Redemption, notice, court orders and the applicable procedure intervene. Section 22-40 now includes a judicial tax-deed auction route, with stated county-trustee exceptions and certificate-date applicability. Neither delinquency nor buying a tax certificate alone is an ordinary deed closing or immediate right to move into the home. The Section 22-40 changes made by Public Act 104-553 apply to matters concerning certificates issued on or after July 10, 2026. That applicability rule belongs to the identified section; it is not a claim that every part of the Act has the same transition rule.
- Use the right kind of charge and closing facts. Ordinary property tax supports local public revenue according to taxable value. A governmental special assessment concerns a particular improvement and special benefit; a private association assessment is another category. A transfer tax concerns a qualifying transfer, not the annual EAV calculation. At closing, use the contract’s tax estimate, dates, payment status and proration convention rather than inventing a universal 105% or 360-day rule.
| Step | Operation | Result |
|---|---|---|
| 1. Value | Determine fair cash or special statutory value | Market or statutory value |
| 2. Assess | Value times assessment level | Assessed value |
| 3. Equalize | Assessed value times equalization factor | EAV |
| 4. Exempt | EAV minus valid exemptions | Taxable EAV |
| 5. Rate | Taxable EAV times composite tax rate | Basic property tax |
| 6. Read the bill | Check year, installments, credits and statutory additions | Actual amount due, not a new appraisal |
The distinctions that matter
| Distinction | How it works | What to notice |
|---|---|---|
| Market value vs. assessed value | Market value estimates the property's full fair cash value. Assessed value applies the legal assessment level or special valuation method. | Full value versus assessment-roll value. |
| Assessed value vs. EAV | Assessed value is the local assessment. EAV is the assessed value after equalization factors are applied. | Before multiplier versus after multiplier. |
| EAV vs. taxable EAV | EAV includes equalization. Taxable EAV is the amount remaining after applicable exemptions are deducted. | Before exemptions versus after exemptions. |
| Exemption vs. assessment freeze | A homestead exemption generally reduces EAV under its formula. A qualifying senior freeze limits a base EAV but does not lock the rate or every bill component. | Value reduction versus base-value limitation. |
| Levy vs. tax rate | A levy is the revenue amount a taxing district requests. The rate allocates that levy across the district's taxable value subject to law. | Dollars requested versus percentage applied. |
| Tax rate vs. tax bill | The rate is applied to taxable value. The bill is the parcel's resulting charge, with applicable additions or adjustments. | Multiplier versus amount due. |
| Equalization vs. reassessment | Equalization changes assessment levels by a factor to improve uniformity. Reassessment revalues the individual parcel based on property evidence. | System factor versus parcel appraisal. |
| Assessment appeal vs. tax-rate objection | An assessment appeal disputes value or uniformity. A rate or levy concern involves taxing-district and extension rules, not merely parcel appraisal. | Value problem versus government-revenue problem. |
| Property tax vs. special assessment | Property tax funds general local services according to taxable value. A special assessment charges specially benefited property for a particular improvement. | General revenue versus specific benefit. |
| Property-tax lien vs. mortgage lien | Section 21-75 provides the stated January 1 levy-year lien and statutory priority. A mortgage is consensual real estate security; this comparison does not decide every federal-priority issue. | Government tax priority versus private loan collateral. |
| Tax sale vs. tax-deed auction | Current definitions distinguish transfer of a lien or certificate from the later property auction. Apply the notice, redemption, court and certificate-date rules. | A tax certificate alone is not immediate ownership or possession. |
| Assessment year vs. payable year | The assessment reflects value for one year, while the associated Illinois bill is generally calculated and paid in the following year. | Value year versus payment year. |
Work through the facts
From market value to tax bill
A nonclassified Illinois parcel has a fair cash value of $300,000, a 33 1/3 percent assessment level, a 1.05 equalization factor, a $10,000 exemption supplied by the question, and an 8 percent composite rate. Use exact one-third, not 0.3333. Assume the given exemption is eligible and no other bill adjustments apply.
- $300,000 times one-third gives $100,000 assessed value.
- $100,000 times 1.05 gives $105,000 EAV.
- $105,000 minus $10,000 gives $95,000 taxable EAV.
- $95,000 times 0.08 gives $7,600.
Answer: The basic property tax is $7,600. This is a stipulated calculation, not a county rate, exemption award or actual parcel bill.
EAV is already supplied
A question gives EAV of $84,000, exemptions of $9,000, and a tax rate of 7.2 percent. The exemptions are eligible and have not yet been deducted. Assume no other adjustments.
- Do not multiply by the assessment level because EAV is already known.
- $84,000 minus $9,000 gives $75,000 taxable EAV.
- $75,000 times 0.072 gives $5,400.
Answer: The basic property tax is $5,400.
Rate stated per $100
Taxable EAV is $120,000 and the rate is $6.50 per $100 of taxable value. The taxable base is already net of exemptions; no other bill adjustments apply.
- $6.50 per $100 equals 6.5 percent or 0.065.
- $120,000 times 0.065 equals $7,800.
- Dividing value by 100 and multiplying by $6.50 gives the same result.
Answer: The tax is $7,800.
The senior freeze does not freeze the bill
An exercise holds an eligible senior homeowner’s taxable EAV at $60,000 with all other components unchanged. The aggregate rate rises from 7% to 8%. Assume no other bill adjustments.
- $60,000 × 0.07 = $4,200.
- $60,000 × 0.08 = $4,800.
- The $600 difference comes from the rate, even with the same supplied taxable base.
Answer: The basic tax rises by $600. A freeze of qualifying base EAV is not a frozen tax bill or a promise that every value component stays fixed.
A high bill is not always a high assessment
Two similar homes have equal taxable EAVs but sit in different combinations of school, fire, park, and municipal districts. Hold all other bill items equal; this is not evidence that either actual home is overassessed.
- Their property values and assessments can be equal.
- Each parcel can have a different composite rate because district boundaries differ.
- The resulting bills can therefore differ without an assessment error.
Answer: The rate and district overlap can explain the difference.
The assessment appeal targets the wrong issue
An owner agrees that the fair cash value and uniformity are correct but objects that the school district increased its levy.
- The owner is not alleging a valuation or uniformity error.
- A board-of-review assessment complaint addresses the parcel assessment.
- Levy and rate concerns follow different public and legal processes.
Answer: The stated complaint concerns the levy, not a demonstrated assessment error. The actual available challenge depends on its legal basis and procedure; a high bill alone does not prove the assessment is wrong.
Unpaid taxes affect title
A title search shows unpaid Illinois property taxes from the levy year while a mortgage is also recorded against the parcel.
- Section 21-75 supplies the stated prior and first lien from January 1 of the levy year.
- Delinquency is not the event that first creates that lien.
- Read the actual tax and title records, amounts and applicable resolution procedure; do not assume a mortgage date settles every priority issue.
Answer: The unpaid tax is a priority title issue under the stated Illinois rule. This exercise does not determine a federal lien contest, authorize a payoff or establish that the property must be sold.
A larger tax base can change the rate
A simplified district needs a $4,000,000 levy and has a taxable base of $200,000,000. Next year the levy stays $4,000,000 while the base becomes $250,000,000. Assume no statutory limits, other adjustments or other districts.
- $4,000,000 ÷ $200,000,000 = 0.02, or 2%.
- $4,000,000 ÷ $250,000,000 = 0.016, or 1.6%.
- The same levy spread over a larger base requires a lower rate in this simplified setup.
Answer: The district rate falls from 2% to 1.6%. That is a 0.4 percentage-point decrease, or a 20% relative decrease. It does not predict any particular homeowner’s full bill.
Two rates, two denominators
An exercise supplies a $320,000 market value, $96,000 taxable EAV and a $7,680 basic annual tax. These are independent supplied values; do not recreate an unstated assessment or exemption calculation.
- $7,680 ÷ $96,000 = 0.08, or 8%, using taxable EAV.
- $7,680 ÷ $320,000 = 0.024, or 2.4%, using full market value.
- The denominators answer different questions.
Answer: The aggregate rate is 8% on the stated taxable EAV; the effective rate is 2.4% of the supplied full market value. Neither is a statewide rate or a prediction for another parcel.
A new certificate is not the later deed
An exercise supplies an Illinois tax certificate issued July 11, 2026. A purchaser says the certificate itself permits immediate entry into the home. No facts establish completed redemption, notice, court or deed procedures.
- The certificate was issued after the July 10, 2026 effective date identified for the Section 22-40 changes.
- A tax-lien or certificate sale is distinct from the property’s tax-deed auction.
- The issue date alone does not establish completion of the applicable statutory route; Section 21-90 county-trustee exceptions and actual proceedings remain relevant.
Answer: The certificate alone does not establish immediate ordinary ownership or possession. The later route and requirements must be satisfied under the applicable law; this example does not calculate a redemption deadline, award surplus equity or approve entry.
Mistakes to avoid
- Multiplying market value directly by the composite tax rate First determine whether assessment, equalization, and exemptions must be applied to reach taxable EAV.
- Applying the one-third level twice If assessed value or EAV is already given, do not recreate it from market value.
- Treating EAV as value after exemptions EAV is value after equalization. Exemptions generally come next to produce taxable EAV.
- Assuming every Illinois parcel uses one-third Cook County classifies property, and farmland and other statutory categories can use different methods.
- Assuming Illinois sets one property-tax rate Local levies, tax bases, legal rules, and overlapping districts produce parcel rates.
- Calling a levy the tax rate The levy is a dollar request. The rate allocates the allowed extension across taxable value.
- Freezing the entire senior tax bill The qualifying program freezes a base EAV, not tax rates or every future value change.
- Subtracting exemptions from market value Illinois homestead exemptions generally reduce EAV, not the full market-value starting point.
- Appealing only because the bill increased Identify whether the cause is assessment, equalization, exemption, levy, rate, district boundary, prior-year adjustment, or delinquency.
- Ignoring the assessment year Illinois bills are generally paid in the year after assessment, so title and proration questions must keep the years straight.
- Giving the assessor every job Assessment, review, equalization, levy, extension, billing, collection, and distribution involve different officials and bodies.
- Putting the mortgage ahead of delinquent property tax Section 21-75 provides the stated first-priority lien from January 1 of the levy year, not only after delinquency. Do not use this lesson to adjudicate federal priority.
- Treating tax sale as an immediate ordinary deed sale A tax certificate and a tax-deed auction are different stages. Apply current statutory routes, notice, redemption, court requirements and certificate-date rules before deciding title or possession.
- Using property tax and special assessment as synonyms Property tax supports general local revenue. A special assessment targets a specific improvement and specially benefited parcels.
- Calling these official PSI questions These are original practice questions aligned to the public outline and current sources.
- Treating PTELL as a personal tax-bill cap PTELL limits qualifying district extensions under its rules. It does not cap every individual assessment or tax bill.
- Stopping tax payments after an appeal An assessment appeal does not suspend the tax payment obligation. Payment and appeal rights follow their actual procedures.
- Forecasting the bill from the equalization factor alone The tax base, exemptions, levy, rates and other lawful bill items can also change.
Check your understanding
These are original teaching questions, not recalled or predicted PSI questions. Answer first, then explain why the other choices fail.
1. A parcel has market value of $240,000 and an assessment level of 33 1/3 percent. What is assessed value before equalization? Use exact one-third.
- $240,000
- $80,000
- $60,000
- $160,000
Show answer and explanation
Answer: B. $80,000
$240,000 times one-third equals $80,000.
2. Assessed value is $90,000 and the equalization factor is 1.10. What is EAV before exemptions?
- $100,000
- $81,000
- $99,000
- $90,000
Show answer and explanation
Answer: C. $99,000
$90,000 times 1.10 equals $99,000 EAV.
3. EAV is $100,000, applicable exemptions total $8,000, and the tax rate is 7 percent. What is the basic tax? The exemptions are eligible and no other adjustments apply.
- $92,000
- $6,440
- $7,560
- $7,000
Show answer and explanation
Answer: B. $6,440
Taxable EAV is $92,000. Multiplying by 0.07 gives $6,440.
4. Which official generally calculates property-tax rates and extends taxes after receiving levies in Illinois?
- Listing broker
- Mortgage appraiser
- Home inspector
- County clerk
Show answer and explanation
Answer: D. County clerk
Taxing districts levy, and the county clerk performs extension and rate functions under the property-tax cycle.
5. Which statement about the Illinois senior assessment freeze is accurate?
- It guarantees an unchanged tax bill
- It can freeze a qualifying base EAV, while rates can still change
- It removes every property lien
- It applies automatically to every owner over age 55
Show answer and explanation
Answer: B. It can freeze a qualifying base EAV, while rates can still change
The program limits qualifying assessment growth, not the tax rate or every bill component.
6. Two parcels have the same taxable EAV but different composite rates. What is the most likely immediate result?
- Neither parcel pays property tax
- They must have identical bills
- The parcel with the higher rate has the higher basic tax
- Both assessments are invalid
Show answer and explanation
Answer: C. The parcel with the higher rate has the higher basic tax
Basic tax equals taxable value times rate. Equal bases with different rates produce different bills.
7. Which issue is most directly suited to an assessment appeal?
- The school board held a budget meeting
- The county treasurer changed office hours
- A buyer dislikes all taxes
- The assessor overstated market value compared with credible evidence
Show answer and explanation
Answer: D. The assessor overstated market value compared with credible evidence
Assessment review addresses valuation, classification, factual property data, and uniformity through the proper evidence and deadline.
8. Under the opening paragraph of 35 ILCS 200/21-75, how is the Illinois property-tax lien ranked?
- Behind every recorded mortgage
- As personal property only
- As a prior and first lien superior to other liens and encumbrances
- As an optional lease payment
Show answer and explanation
Answer: C. As a prior and first lien superior to other liens and encumbrances
The statute states prior and first priority from January 1 of the levy year, including the specified additions. It does not wait for delinquency. This question does not determine a federal-priority dispute.
9. Which sequence is correct for the standard Illinois exam calculation?
- EAV, market value, levy, appraisal
- Rate, exemptions, market value, deed
- Market value, assessed value, EAV, exemptions, rate
- Tax sale, lease, assessment, title
Show answer and explanation
Answer: C. Market value, assessed value, EAV, exemptions, rate
That order moves from full value through assessment and equalization to the taxable base and bill.
10. What most clearly distinguishes a special assessment from ordinary property tax?
- It is charged for a specific improvement benefiting identified property
- It is always voluntary
- It can never create a lien
- It is the same as income tax
Show answer and explanation
Answer: A. It is charged for a specific improvement benefiting identified property
Special assessments connect a targeted improvement and special benefit, while property taxes support general local revenue.
11. Taxable EAV is $120,000 and the rate is $6.50 per $100. No other adjustments apply. What is the basic tax?
- $78,000
- $120,000
- $7,800
- $780
Show answer and explanation
Answer: C. $7,800
Divide $6.50 by $100 to obtain 0.065, then multiply by $120,000. The base is already taxable EAV; do not subtract exemptions again.
12. An exercise supplies EAV after equalization. Which step would improperly repeat work?
- Applying the assessment level and equalization factor to that EAV again
- Checking whether the value is already net of exemptions
- Subtracting the supplied eligible exemptions once
- Using the stated aggregate rate
Show answer and explanation
Answer: A. Applying the assessment level and equalization factor to that EAV again
Identify the supplied stage first. EAV already includes assessment and equalization; eligible exemptions can still be a later step if not already deducted.
13. Which statement about a supplied $6,000 homestead exemption and a fixed 8% rate is correct?
- It reduces the basic tax by $480 under the stated assumptions
- It guarantees the same savings at every future rate
- It removes every mortgage
- It reduces the bill by $6,000
Show answer and explanation
Answer: A. It reduces the basic tax by $480 under the stated assumptions
The $6,000 reduces EAV. At the stipulated unchanged rate, $6,000 × 0.08 = $480. Eligibility, other amounts and future rates are separate.
14. A standard Illinois property assessment is for 2025. When is its related bill generally calculated and paid?
- Only when the owner sells
- 2026
- Always the day of assessment
- 2024
Show answer and explanation
Answer: B. 2026
The general system has an assessment year followed by billing and collection in the next year. Actual county notices and exceptional schedules still control.
15. Does the Section 21-75 lien first arise only after the owner misses a payment?
- Yes, only after foreclosure
- Yes, only after a mortgage is recorded
- No; the stated trigger is January 1 of the levy year
- Yes, only after a tax sale
Show answer and explanation
Answer: C. No; the stated trigger is January 1 of the levy year
Read the statute’s levy-year trigger. Amounts due, delinquency, enforcement and title resolution are separate issues.
16. An owner buys an Illinois delinquent-tax certificate. What follows from that fact alone?
- The buyer can move into the home that day
- A private mortgage note is automatically forgiven
- All redemption rights vanish immediately
- The certificate alone does not confer immediate ordinary ownership or possession
Show answer and explanation
Answer: D. The certificate alone does not confer immediate ordinary ownership or possession
The current Code distinguishes tax sale of a lien or certificate from a later tax-deed auction. Actual notice, redemption, court, route and date rules still matter.
17. Which statement about PTELL is accurate?
- It guarantees every owner’s bill rises by no more than 5%
- It fixes every county’s rate
- It does not cap every individual assessment or tax bill
- It eliminates local levies
Show answer and explanation
Answer: C. It does not cap every individual assessment or tax bill
The law addresses qualifying district extensions under its rules. An individual bill can change for other reasons; do not turn a district limitation into a personal guarantee.
18. An owner appeals a county board-of-review assessment decision. Does that alone postpone tax payment?
- No; taxes remain payable pending the appeal
- Yes, if the owner simply dislikes the rate
- Yes, if the home has a mortgage
- Yes, until every possible court appeal ends
Show answer and explanation
Answer: A. No; taxes remain payable pending the appeal
IDOR distinguishes assessment review from payment. The actual appeal route and filing requirements must be followed; filing alone does not suspend the tax obligation.
19. A district levy is $4,000,000 and the taxable base is $200,000,000. With no other limits or adjustments, what is the rate?
- 50%
- 20%
- 0.2%
- 2%
Show answer and explanation
Answer: D. 2%
$4,000,000 ÷ $200,000,000 = 0.02, or 2%. The actual extension process has legal limits and adjustments beyond this teaching setup.
20. Under a stipulated accelerated-billing setup, last year’s annual bill was $8,000. What is 55% of that bill?
- $14,545.45
- $4,000
- $4,400
- $8,000
Show answer and explanation
Answer: C. $4,400
$8,000 × 0.55 = $4,400. This prior-bill-based installment does not establish the current year’s full bill or an actual county due date.
21. A basic tax is $7,680, taxable EAV is $96,000 and supplied full market value is $320,000. Which rate pair is correct?
- 8% aggregate; 2.4% effective
- Both rates must be 8%
- 80% aggregate; 24% effective
- 2.4% aggregate; 8% effective
Show answer and explanation
Answer: A. 8% aggregate; 2.4% effective
Aggregate uses the stated taxable EAV: 7,680 ÷ 96,000 = 0.08. Effective uses full market value: 7,680 ÷ 320,000 = 0.024. These are stipulated values, not a fresh assessment of an actual parcel.
22. A certificate was issued July 11, 2026. What does the Section 22-40 applicability rule establish by itself?
- The buyer may immediately evict the occupant
- The certificate is already an ordinary deed
- Its identified 2026 changes apply to the certificate matter, not that every later deed or possession requirement is complete
- Every older certificate follows the identical amended route
Show answer and explanation
Answer: C. Its identified 2026 changes apply to the certificate matter, not that every later deed or possession requirement is complete
Section 22-40(h) addresses certificates issued on or after the Act’s July 10, 2026 effective date. Actual route, exceptions, redemption, notice and court requirements remain separate. Do not generalize this transition clause to every provision.
23. For the 2026 tax year, generally payable in 2027, which income-year pairing belongs to the senior assessment-freeze test?
- The payment-year label alone, regardless of assessment year
- An automatic exemption for every person over 55
- $75,000 household-income ceiling using 2025 income, with other eligibility conditions still required
- A $75,000 automatic bill credit for everyone
Show answer and explanation
Answer: C. $75,000 household-income ceiling using 2025 income, with other eligibility conditions still required
The tax year and preceding calendar-year household income matter. The ceiling is only one condition; age, qualifying property interest, residence, tax liability, application and other statutory conditions remain. It does not convert every bill paid in 2026 to the new threshold.
24. A parcel’s equalization factor rises. What does that alone establish about its final bill?
- It does not by itself establish a proportional increase in the final tax bill
- Every individual PTELL cap is automatically violated
- The bill must rise by exactly the same percentage
- The levy must increase by the same percentage
Show answer and explanation
Answer: A. It does not by itself establish a proportional increase in the final tax bill
Exemptions, district tax bases, levies, rates and other bill items can also change. A calculation holding every other item fixed is different from a real-world forecast.
Common questions
What is property tax in Illinois?
It is a local value-based tax, often called ad valorem. Taxing districts use it to support public services. The relevant value base, levy, rate and applicable relief determine the basic calculation; it is not a single statewide percentage of every home’s sale price.
What is fair cash value?
Section 1-50 uses the amount for which property can sell in ordinary business and trade between willing parties without duress. That market-value concept differs from assessed value, EAV and the taxable amount. A sale can supply evidence without resolving every valuation or classification question.
Is all Illinois property assessed at one-third of market value?
No. Most property follows the one-third method, but Cook County classifications and special statutory methods matter. Ordinary Cook residential and commercial categories commonly use 10% and 25%; other classes and incentives need their own rules. Farmland and preferential assessments are not solved by applying one-third indiscriminately. Use the supplied lawful method in an exam exercise.
What is the difference between assessed value, EAV and taxable EAV?
Assessed value is the assessment-roll value. EAV reflects applicable equalization. In the standard calculation, eligible exemptions are then deducted to reach taxable EAV. If a question gives the later-stage number, do not repeat earlier steps or deduct exemptions twice.
How do I calculate the property-tax bill?
For a standard problem: market value × stated assessment level = assessed value; assessed value × applicable equalization factor = EAV; EAV − eligible exemptions = taxable EAV; taxable EAV × aggregate rate = basic tax. Convert the rate first. Special assessments, penalties, credits and other actual bill items require their own facts; the formula does not calculate an individual county bill from a sale price alone.
Is $6.50 per $100 the same as 6.5%?
Yes. Both equal a 0.065 multiplier. On $120,000 of taxable EAV, the resulting basic tax is $7,800 before other adjustments. One mill is different: it is $1 per $1,000, or 0.001. Read the stated rate unit rather than treating every number as a percentage.
An aggregate rate and an effective rate can both be correct because they use different bases. For example, a $7,680 basic tax on $96,000 taxable EAV is an 8% aggregate rate; the same $7,680 divided by a supplied $320,000 full market value is a 2.4% effective rate. Do not apply the 8% to full market value or assess an effective rate a second time.
Does an exemption reduce the bill dollar for dollar?
A typical Illinois homestead exemption reduces EAV, not the bill by that same dollar amount. With eligibility and all other components held fixed, a $6,000 EAV reduction at 8% changes the basic tax by $480. Future savings depend on future rates and actual eligibility; the exemption is not a $6,000 check.
Does the senior assessment freeze freeze my tax bill?
No. It limits a qualifying base EAV under the program’s conditions. Rates and other bill components can change, and certain improvements can affect the relevant value. The name does not promise an unchanged total bill or automatic eligibility based on age alone.
Why can bills differ for homes with the same taxable EAV?
Different combinations of school, municipal, fire, park, library and other districts can produce different aggregate rates. Exemptions, adjustments and other bill items can also differ. Compare the tax code area, value stage, rates and actual bill items before concluding that an assessment is wrong.
Who decides the value and who sends the tax bill?
Assessors perform valuation work, review bodies address assessment issues, and IDOR handles state equalization. Taxing districts levy; the county clerk performs extension and rate work; the collector prepares bills and collects and distributes the revenue. Their responsibilities overlap in specified ways, so the assessor is not the sole official responsible for every stage.
Can I appeal because the bill is high?
Identify the cause first. Credible market-value evidence, unequal assessment or incorrect property data can support an assessment complaint. A disliked levy or tax rate is a different issue. IDOR describes early correction with the assessor, then the ordinary written board-of-review route and possible further PTAB or circuit-court proceedings. Check the applicable county notices, deadlines and evidence requirements; an assessment appeal does not suspend payment.
When does the Illinois property-tax lien begin?
Section 21-75 states January 1 of the year in which the taxes are levied, with prior and first lien language covering the specified penalties, interest and costs. It does not begin only when a payment becomes overdue. Payment and sale under the Code have their own consequences. An actual title or federal-priority dispute needs its own records and governing law.
Does buying a tax certificate make me the owner?
The certificate alone does not provide immediate ordinary ownership or possession. Current statutory definitions distinguish a tax sale of a lien or certificate from a tax-deed auction involving the property. Redemption, notice, court proceedings, applicable routes and certificate dates matter. Do not treat the certificate as a normal buyer’s deed or permission to enter a home.
Where is property tax on the Illinois broker exam outline?
Government taxation and special assessments appear in national II.A.1. Related calculations and Illinois tax subjects can appear elsewhere. The entire Land Use Controls domain has five of 100 scored national questions across multiple subjects; there is no five-question property-tax quota. These practice questions are original, with explanations rather than an official PSI score prediction.
What is the General Homestead Exemption amount?
For the standard current rule, the exemption reflects qualifying growth in EAV over the 1977 base, up to $10,000 in Cook County, $8,000 in counties contiguous to Cook and $6,000 elsewhere. These are maximum EAV reductions under the statutory formula, not automatic cash grants or guaranteed bill reductions. The qualifying residence, interest, tax liability, application and applicable exceptions must be checked. Do not use a proposed bill’s larger amount as current law.
Which senior-freeze income limit applies to a bill paid in 2026?
Start with the assessment or tax year, not only the year of payment. The 2026 tax-year ceiling is $75,000 of preceding-calendar-year household income, ordinarily 2025 income, for taxes generally payable in 2027. The 2025 tax-year program, generally payable in 2026, has the $65,000 ceiling and uses 2024 income. Age, qualifying ownership or interest, residence, tax liability, annual application and other conditions still apply. This comparison is not a ruling on an individual application or a promise about future-year amendments.
What changed in Illinois tax-deed procedures in July 2026?
Public Act 104-553 took effect July 10, 2026. Current definitions distinguish a tax sale of a lien or certificate from a tax-deed auction. Section 22-40 includes a judicial tax-deed auction route, with county-trustee exceptions, and applies its identified changes to matters concerning certificates issued on or after that effective date. An older certificate needs the law applicable to its dates and facts; do not simply substitute the new route. Redemption, notice, court findings and related provisions remain important. This glossary does not compute a live deadline, decide possession, or audit all auction, surplus-equity and transition provisions.
Does PTELL cap my bill at 5%?
No. PTELL concerns extensions of qualifying non-home-rule taxing districts, with statutory limits, exclusions and adjustments. It does not cap every individual bill or assessment. A changed share of the tax base, exemptions, voter approvals and other relevant items can affect a parcel’s bill. A senior assessment freeze is a separate program, and neither label guarantees an unchanged payment.
