Property tax: from market value to local tax bill

Property-tax questions get easier when you stop treating the bill as one mysterious percentage. Illinois uses a sequence. Property is valued, assessed, reviewed, equalized, reduced by qualifying exemptions, matched to local levies, billed, and collected. On the exam, identify which number you have before doing any arithmetic. Market value, assessed value, EAV, taxable EAV, tax rate, and tax bill are not interchangeable.

Last updated: August 1, 2026

What does this exam area cover?

Short answer: Property tax is a value-based local tax on real property. For a standard exam calculation, move from market value to assessed value, apply equalization to reach EAV, subtract applicable exemptions, and multiply taxable EAV by the composite tax rate. Illinois has no single statewide property-tax rate. Local taxing-district levies and the parcel's taxable value produce the bill.

Official section
National II.A.1: Government right to impose property taxes

Part of 5% of the national broker portion
Expected scored items
The current PSI outline assigns Land Use Controls about 5 of the 100 scored national broker items

This guide follows the PSI Illinois Candidate Information Booklet effective June 24, 2026, the current Illinois Property Tax Code, and Illinois Department of Revenue materials checked through August 1, 2026. Illinois property taxation has county-specific administration, classified-property rules in Cook County, statutory exceptions, changing exemptions, local deadlines, PTELL issues, special assessments, tax-sale procedures, and litigation rules. The exam framework cannot determine a real parcel's current bill or appeal rights without its county records and current law.

Which distinctions produce the most mistakes?

Terms
Market value vs. assessed value
Difference
Market value estimates the property's full fair cash value. Assessed value applies the legal assessment level or special valuation method.
Question cue
Full value versus assessment-roll value.
Terms
Assessed value vs. EAV
Difference
Assessed value is the local assessment. EAV is the assessed value after equalization factors are applied.
Question cue
Before multiplier versus after multiplier.
Terms
EAV vs. taxable EAV
Difference
EAV includes equalization. Taxable EAV is the amount remaining after applicable exemptions are deducted.
Question cue
Before exemptions versus after exemptions.
Terms
Exemption vs. assessment freeze
Difference
An exemption reduces EAV under its formula. A qualifying freeze holds a base EAV but does not freeze the tax rate or guarantee an unchanged bill.
Question cue
Value reduction versus base-value limitation.
Terms
Levy vs. tax rate
Difference
A levy is the revenue amount a taxing district requests. The rate allocates that levy across the district's taxable value subject to law.
Question cue
Dollars requested versus percentage applied.
Terms
Tax rate vs. tax bill
Difference
The rate is applied to taxable value. The bill is the parcel's resulting charge, with applicable additions or adjustments.
Question cue
Multiplier versus amount due.
Terms
Equalization vs. reassessment
Difference
Equalization changes assessment levels by a factor to improve uniformity. Reassessment revalues the individual parcel based on property evidence.
Question cue
System factor versus parcel appraisal.
Terms
Assessment appeal vs. tax-rate objection
Difference
An assessment appeal disputes value or uniformity. A rate or levy concern involves taxing-district and extension rules, not merely parcel appraisal.
Question cue
Value problem versus government-revenue problem.
Terms
Property tax vs. special assessment
Difference
Property tax funds general local services according to taxable value. A special assessment charges specially benefited property for a particular improvement.
Question cue
General revenue versus specific benefit.
Terms
Property-tax lien vs. mortgage lien
Difference
The Illinois property-tax lien is statutory and first in priority under section 21-75. A mortgage lien arises from the borrower's security instrument.
Question cue
Government tax priority versus private loan collateral.
Terms
Tax sale vs. ordinary property sale
Difference
An Illinois tax sale initially involves delinquent-tax rights and redemption procedures, not the same immediate fee-title transfer as an ordinary closing.
Question cue
Delinquency process versus negotiated conveyance.
Terms
Assessment year vs. payable year
Difference
The assessment reflects value for one year, while the associated Illinois bill is generally calculated and paid in the following year.
Question cue
Value year versus payment year.

The T-A-X method for property-tax questions

  1. Tax base: identify market value, assessed value, EAV, or taxable EAV. Never restart a step the problem has already completed.
  2. Assessment sequence: apply the stated assessment level, then equalization, then exemptions in that order unless the question expressly gives another instruction.
  3. X the rate: convert percent, decimal, mills, or dollars per $100 into the correct multiplier and apply it to taxable value.
  4. Trace the official: assessor values, review bodies hear assessment disputes, taxing districts levy, the county clerk extends rates, and the treasurer or collector bills and distributes.
  5. Title and timing: check the levy year, payable year, proration convention, delinquency, first-priority lien, tax sale, redemption, and payoff evidence.

How do the rules work in scenarios?

From market value to tax bill

Scenario: 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.

  1. $300,000 times one-third gives $100,000 assessed value.
  2. $100,000 times 1.05 gives $105,000 EAV.
  3. $105,000 minus $10,000 gives $95,000 taxable EAV.
  4. $95,000 times 0.08 gives $7,600.

Answer: The basic property tax is $7,600.

EAV is already supplied

Scenario: A question gives EAV of $84,000, exemptions of $9,000, and a tax rate of 7.2 percent.

  1. Do not multiply by the assessment level because EAV is already known.
  2. $84,000 minus $9,000 gives $75,000 taxable EAV.
  3. $75,000 times 0.072 gives $5,400.

Answer: The basic property tax is $5,400.

Rate stated per $100

Scenario: Taxable EAV is $120,000 and the rate is $6.50 per $100 of taxable value.

  1. $6.50 per $100 equals 6.5 percent or 0.065.
  2. $120,000 times 0.065 equals $7,800.
  3. 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

Scenario: A qualifying homeowner's base EAV remains unchanged, but the composite local tax rate rises.

  1. The program addresses the qualifying EAV base.
  2. It does not lock the local tax rate.
  3. A higher rate applied to the same taxable base can produce a higher bill.

Answer: The tax bill can rise even though the qualifying base EAV is frozen.

A high bill is not always a high assessment

Scenario: Two similar homes have equal taxable EAVs but sit in different combinations of school, fire, park, and municipal districts.

  1. Their property values and assessments can be equal.
  2. Each parcel can have a different composite rate because district boundaries differ.
  3. 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

Scenario: An owner agrees that the fair cash value and uniformity are correct but objects that the school district increased its levy.

  1. The owner is not alleging a valuation or uniformity error.
  2. A board-of-review assessment complaint addresses the parcel assessment.
  3. Levy and rate concerns follow different public and legal processes.

Answer: An assessment appeal does not directly correct the stated levy objection.

Unpaid taxes affect title

Scenario: A title search shows unpaid Illinois property taxes from the levy year while a mortgage is also recorded against the parcel.

  1. Section 21-75 makes the taxes and statutory additions a prior and first lien.
  2. The tax lien is superior to other liens and encumbrances under the statute.
  3. Closing requires a current payoff and title treatment rather than assuming the mortgage has priority.

Answer: The property-tax lien is a priority title issue that must be resolved.

What are the common exam traps?

Trap
Multiplying market value directly by the composite tax rate
Correction
First determine whether assessment, equalization, and exemptions must be applied to reach taxable EAV.
Trap
Applying the one-third level twice
Correction
If assessed value or EAV is already given, do not recreate it from market value.
Trap
Treating EAV as value after exemptions
Correction
EAV is value after equalization. Exemptions generally come next to produce taxable EAV.
Trap
Assuming every Illinois parcel uses one-third
Correction
Cook County classifies property, and farmland and other statutory categories can use different methods.
Trap
Assuming Illinois sets one property-tax rate
Correction
Local levies, tax bases, legal rules, and overlapping districts produce parcel rates.
Trap
Calling a levy the tax rate
Correction
The levy is a dollar request. The rate allocates the allowed extension across taxable value.
Trap
Freezing the entire senior tax bill
Correction
The qualifying program freezes a base EAV, not tax rates or every future value change.
Trap
Subtracting exemptions from market value
Correction
Illinois homestead exemptions generally reduce EAV, not the full market-value starting point.
Trap
Appealing only because the bill increased
Correction
Identify whether the cause is assessment, equalization, exemption, levy, rate, district boundary, prior-year adjustment, or delinquency.
Trap
Ignoring the assessment year
Correction
Illinois bills are generally paid in the year after assessment, so title and proration questions must keep the years straight.
Trap
Giving the assessor every job
Correction
Assessment, review, equalization, levy, extension, billing, collection, and distribution involve different officials and bodies.
Trap
Putting the mortgage ahead of delinquent property tax
Correction
Illinois section 21-75 makes the property-tax lien prior and first under its terms.
Trap
Treating tax sale as an immediate ordinary deed sale
Correction
Illinois tax sales involve certificates, statutory notice, redemption, petition, and tax-deed procedures.
Trap
Using property tax and special assessment as synonyms
Correction
Property tax supports general local revenue. A special assessment targets a specific improvement and specially benefited parcels.
Trap
Calling these official PSI questions
Correction
These are original practice questions aligned to the public outline and current sources.

Can you answer these original practice questions?

These questions are original study items aligned to the published outline. They are not copied, recalled, or predicted PSI questions.

1. A parcel has market value of $240,000 and an assessment level of 33 1/3 percent. What is assessed value before equalization?

  1. $60,000
  2. $80,000
  3. $160,000
  4. $240,000
Show answer and explanation

Answer: $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?

  1. $81,000
  2. $90,000
  3. $99,000
  4. $100,000
Show answer and explanation

Answer: $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?

  1. $6,440
  2. $7,000
  3. $7,560
  4. $92,000
Show answer and explanation

Answer: $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?

  1. County clerk
  2. Listing broker
  3. Home inspector
  4. Mortgage appraiser
Show answer and explanation

Answer: 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?

  1. It guarantees an unchanged tax bill
  2. It can freeze a qualifying base EAV, while rates can still change
  3. It removes every property lien
  4. It applies automatically to every owner over age 55
Show answer and explanation

Answer: 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?

  1. They must have identical bills
  2. The parcel with the higher rate has the higher basic tax
  3. Both assessments are invalid
  4. Neither parcel pays property tax
Show answer and explanation

Answer: 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?

  1. The assessor overstated market value compared with credible evidence
  2. The school board held a budget meeting
  3. The county treasurer changed office hours
  4. A buyer dislikes all taxes
Show answer and explanation

Answer: 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. How does 35 ILCS 200/21-75 rank the Illinois property-tax lien?

  1. Behind every recorded mortgage
  2. As a prior and first lien superior to other liens and encumbrances
  3. As an optional lease payment
  4. As personal property only
Show answer and explanation

Answer: As a prior and first lien superior to other liens and encumbrances

That priority language is stated in the current Property Tax Code.

9. Which sequence is correct for the standard Illinois exam calculation?

  1. Market value, assessed value, EAV, exemptions, rate
  2. Rate, exemptions, market value, deed
  3. EAV, market value, levy, appraisal
  4. Tax sale, lease, assessment, title
Show answer and explanation

Answer: 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?

  1. It is charged for a specific improvement benefiting identified property
  2. It can never create a lien
  3. It is always voluntary
  4. It is the same as income tax
Show answer and explanation

Answer: 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.

Questions students ask about What Is Property Tax? Illinois Real Estate Exam Guide

What is property tax in real estate?

Property tax is an ad valorem tax imposed according to taxable property value. In Illinois it is a local tax used by local taxing districts. The bill depends on the parcel's taxable equalized assessed value and the composite rate produced by the levies and tax bases of the districts serving that parcel.

Does Illinois have one statewide property-tax rate?

No. The Illinois Department of Revenue states that there is no set property-tax rate for the state. Local taxing districts determine their levies, and the county clerk calculates rates based on those levies, legal limits, and taxable equalized assessed value within each district.

What is fair cash value in Illinois property tax?

The Property Tax Code defines fair cash value as the amount for which property can be sold in the due course of business and trade, not under duress, between a willing buyer and willing seller. It is the market-value starting point, not necessarily the number to which the tax rate is applied.

What is assessed value?

Assessed value is the value entered on the assessment rolls for tax purposes. Outside counties that lawfully classify property, Illinois generally values property at 33 1/3 percent of fair cash value, subject to exceptions such as farmland, preferential assessments, and other statutory treatments.

What is equalized assessed value or EAV?

EAV is assessed value after applicable equalization factors are applied. Equalization is intended to bring assessment levels to the legal level and improve uniformity. Homestead exemptions are then generally deducted from EAV to reach the taxable amount used in the basic tax calculation.

How is an Illinois property-tax bill calculated for exam purposes?

Use the sequence market value times assessment level equals assessed value; assessed value times equalization factor equals EAV; EAV minus applicable exemptions equals taxable EAV; taxable EAV times the composite tax rate equals the basic tax. Read the question carefully because it may already provide EAV or a rate as a percent, decimal, or dollars per $100.

Does a homestead exemption erase property tax?

No. A homestead exemption generally reduces EAV by the applicable statutory amount or formula. The remaining taxable EAV is still multiplied by the tax rate. Eligibility, amount, application, renewal, and county administration depend on the specific current exemption.

Does the senior assessment freeze freeze the tax bill?

No. The Illinois Department of Revenue explains that the qualifying program freezes an eligible base EAV, not the tax rate or total bill. A bill can still change because tax rates change or because nonfrozen items, such as certain improvements, affect value.

What happens when Illinois property tax is unpaid?

Unpaid taxes can become delinquent, incur statutory charges, and enter tax-sale and redemption procedures. Section 21-75 states that property taxes, penalties, interest, and costs are a prior and first lien superior to other liens and encumbrances from January 1 of the levy year until payment or sale under the Code.

Can an owner appeal an Illinois property-tax assessment?

Yes. An owner can challenge valuation or uniformity through the local assessment-review process and may have further routes to a board of review, the Illinois Property Tax Appeal Board, or court, depending on the property, county, issue, deadlines, and procedural requirements. An assessment appeal is not simply a complaint that the bill feels high.

Where is property tax tested on the current Illinois broker exam outline?

The PSI Illinois Candidate Information Booklet effective June 24, 2026 lists the government's right to impose property taxes and special assessments under National II.A.1, Land Use Controls. Property-tax math can also appear through valuation, prorations, and calculation skills.

Are these official PSI questions or tax advice?

No. The practice items are original. The page teaches exam concepts and does not replace county records, exemption guidance, an appeal professional, a title company, an attorney, or tax advice. Authorities were reviewed through August 1, 2026.

Primary sources

The current official outline controls the tested scope. Statutes, regulations, and official agency materials control when a general study rule and a jurisdiction-specific rule differ.
