Illinois real estate taxes and exemptions

A property-tax bill is the last page of a much longer process. The assessor values the parcel, the state equalizes, taxing districts levy, the clerk extends rates, exemptions reduce qualifying EAV, and the collector bills in the following year. Once those jobs are separated, the math and the exemption questions become far easier to control.

Last updated: August 1, 2026

What does current Illinois authority require?

Short answer: Illinois property tax is a local ad valorem tax administered through a two-year cycle. For ordinary exam math, find assessed value from fair cash value, apply the state equalization factor to get EAV, subtract qualifying EAV exemptions, and multiply the taxable EAV by the aggregate local rate. The General Homestead Exemption maximum for 2026 is $10,000 EAV in Cook, $8,000 in counties contiguous to Cook, and $6,000 elsewhere. The Senior Citizens Homestead maximum is $8,000 in Cook and contiguous counties or $5,000 elsewhere. The 2026 low-income senior assessment-freeze income ceiling is $75,000, but the program freezes qualifying EAV, not the final bill.

The VALUE method for Illinois property tax

  1. Verify the tax year and location. Identify the January 1 assessment year, following payable year, county category, property class, and taxing districts.
  2. Assess the property. Multiply fair cash value by the supplied assessment level unless the problem already gives assessed value.
  3. Lift the assessment to EAV. Apply the state equalization factor, or use the stated EAV when supplied.
  4. Use only qualifying exemptions. Match residence, age, income, disability, veteran status, improvement, disaster, or institutional use and subtract the authorized EAV amount.
  5. Levy the aggregate rate. Convert the rate to decimal form and multiply it by taxable EAV to find the tax.
  6. Examine timing, appeals, liens, and closing. Separate valuation appeal from tax payment, account for arrears and prorations, and remember the January 1 first lien.
  7. Escalate uncertain eligibility. Brokers can explain the framework and use published records, but county assessment officials, tax counsel, and closing professionals decide parcel-specific applications and adjustments.

Which Illinois distinctions matter most?

Terms
Market value vs. assessed value
Difference
Market value is the fair cash value of the property. Assessed value applies the legal assessment level, often 33 1/3 percent outside Cook for ordinary property.
Question cue
Full property value or assessment fraction?
Terms
Assessed value vs. EAV
Difference
Assessed value comes from the local assessment. EAV is that assessed value after application of the state equalization factor.
Question cue
Before or after the multiplier?
Terms
EAV vs. taxable EAV
Difference
EAV is the equalized figure before exemptions. Taxable EAV is the amount remaining after applicable exemptions are deducted.
Question cue
Before or after relief?
Terms
Levy vs. tax rate
Difference
A levy is the taxing district's requested property-tax revenue. The rate spreads the extended amount over taxable EAV.
Question cue
Revenue requested or percentage applied?
Terms
Assessment appeal vs. tax-rate objection
Difference
The normal board-of-review appeal challenges valuation or assessment uniformity. It does not ask the board to rewrite taxing-district levies or rates.
Question cue
Parcel value error or government budget complaint?
Terms
Homestead exemption vs. judgment homestead
Difference
A property-tax homestead exemption reduces qualifying EAV. The Code of Civil Procedure judgment homestead protects a limited ownership value from certain creditors and does not calculate the tax bill.
Question cue
Tax relief or creditor protection?
Terms
Senior homestead vs. senior freeze
Difference
The senior homestead provides a regional maximum EAV reduction without the freeze's income test. The senior freeze uses a qualifying base-year EAV and a 2026 household-income ceiling of $75,000.
Question cue
Fixed EAV deduction or income-tested base?
Terms
Assessment freeze vs. tax-bill freeze
Difference
The program limits EAV growth. Increased local rates and added improvements can still increase the final bill.
Question cue
Frozen value or frozen dollars?
Terms
Exemption vs. deferral
Difference
An exemption removes qualifying value from the tax base. The senior deferral postpones payment, operates like a loan secured by a lien, and must be repaid with the statutory amount.
Question cue
Tax value removed or payment delayed?
Terms
Nonprofit owner vs. exempt property
Difference
Organizational status does not automatically exempt every parcel. The property must satisfy the constitutional and statutory ownership, actual-use, exclusive-use, and no-profit-use conditions and the approval process.
Question cue
Who owns it, how is it used, and was it approved?

How does the Illinois rule apply?

From market value to tax

Scenario: An ordinary home outside Cook County has a $300,000 fair cash value. The question supplies a 33 1/3 percent assessment level, a 1.05 equalization factor, the full $6,000 General Homestead Exemption, and an 8 percent aggregate tax rate.

  1. $300,000 times one-third produces $100,000 assessed value.
  2. $100,000 times 1.05 produces $105,000 EAV.
  3. Subtract the $6,000 EAV exemption to get $99,000 taxable EAV.
  4. Convert 8 percent to 0.08.
  5. $99,000 times 0.08 equals $7,920.

Answer: The calculated property tax is $7,920.

The exemption applied to the wrong number

Scenario: A candidate subtracts a $6,000 General Homestead Exemption from a home's $300,000 market value before applying the one-third assessment level.

  1. The General Homestead Exemption is an EAV reduction.
  2. Market value must first become assessed value.
  3. The equalization factor then produces EAV.
  4. Only then is the qualifying homestead exemption subtracted.
  5. Subtracting from market value understates the actual exemption effect in the formula and violates the required order.

Answer: The method is wrong. Deduct the exemption from EAV, not market value.

The 2026 senior freeze

Scenario: A 68-year-old qualifying owner has 2026 household income of $72,000 and completes the annual filing. The home's tax rate later rises even though no new improvement is added.

  1. The owner meets the age threshold.
  2. $72,000 is below the enacted $75,000 maximum for taxable year 2026.
  3. The annual application and other residence conditions are stated as satisfied.
  4. The benefit maintains the qualifying base-year EAV comparison.
  5. A later rate increase can still raise the bill.

Answer: The owner can qualify for the 2026 assessment freeze, but the program does not guarantee an unchanged tax bill.

Choosing the regional senior amount

Scenario: A qualifying 70-year-old owner lives in a county contiguous to Cook County. The question asks for the maximum Senior Citizens Homestead Exemption EAV reduction.

  1. The owner meets the stated age and qualification facts.
  2. The county is contiguous to Cook.
  3. For 2023 and later, that county group uses the same senior maximum as Cook.
  4. The amount is an EAV reduction.
  5. No income test is attached to this senior homestead question unless the separate freeze is requested.

Answer: The maximum Senior Citizens Homestead reduction is $8,000 EAV.

Appealing the wrong thing

Scenario: After receiving a high bill, an owner files with the county board of review and argues only that the school district's tax rate is unfair. The owner offers no value, uniformity, or property-record evidence.

  1. The ordinary board complaint addresses assessed value.
  2. Possible grounds include excessive market value, unequal assessment, or inaccurate parcel facts.
  3. The board does not set the school district's budget through an individual assessment appeal.
  4. Waiting until the bill arrives may also miss the assessment deadline.
  5. The owner should have reviewed the assessment notice and local deadline earlier.

Answer: The argument does not establish an assessment appeal. The owner is challenging a rate, not the parcel's assessed value.

The nonprofit's rented storefront

Scenario: A charitable organization owns a building. It uses the second floor for charitable services but leases the entire first-floor storefront to a commercial retailer at market rent.

  1. Charitable ownership alone does not settle exemption.
  2. The actual and exclusive use of each part matters.
  3. The commercial storefront is leased with a view to profit on the stated facts.
  4. Illinois procedures allow officials to identify and assess the taxable portion where appropriate.
  5. The organization must use the county application and IDOR decision process rather than self-declaring the whole parcel exempt.

Answer: Do not assume a whole-parcel exemption. The commercial portion raises a taxable-use issue requiring official review.

Where do candidates misread the Illinois rule?

Trap
Every Illinois property is assessed at exactly one-third of market value.
Correction
Most ordinary property outside Cook uses 33 1/3 percent. Cook classifications, farmland, and preferential assessments can differ.
Trap
EAV and market value are the same number.
Correction
EAV is assessed value after the state equalization factor, not the property's full fair cash value.
Trap
Subtract a homestead exemption from sale price.
Correction
The listed homestead amounts reduce qualifying EAV, not sale price or market value.
Trap
The General Homestead Exemption is a flat $10,000 statewide.
Correction
The current maximum is $10,000 in Cook, $8,000 in contiguous counties, and $6,000 elsewhere.
Trap
The senior homestead and senior freeze are the same benefit.
Correction
The senior homestead is a regional EAV reduction. The freeze is income-tested and limits EAV growth against a base amount.
Trap
The 2026 senior freeze income maximum is still $65,000.
Correction
The enacted maximum is $75,000 for taxable year 2026, $77,000 for 2027, and $79,000 for 2028 and later.
Trap
A senior assessment freeze guarantees the same tax bill forever.
Correction
Rates and added improvements can still change the bill, and eligibility and annual filing must continue.
Trap
An assessment appeal challenges the amount of every local levy.
Correction
The parcel appeal challenges assessed value or uniformity. Taxing-district levies and rates are different issues.
Trap
Property-tax homestead relief is the $50,000 judgment homestead.
Correction
The $50,000 figure protects qualifying value from certain judgment creditors. Property-tax exemptions use separate EAV rules and amounts.
Trap
A nonprofit owner's property is automatically tax exempt.
Correction
Qualifying ownership, actual use, exclusive use, no-profit-use conditions, and formal exemption approval all matter.

Can you apply the rule to a fresh scenario?

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

1. A property has $120,000 assessed value and a 0.95 equalization factor. What is its EAV before exemptions?

  1. $114,000
  2. $120,000
  3. $126,000
  4. $228,000
Show answer and explanation

Answer: $114,000

Multiply assessed value by the equalization factor: $120,000 times 0.95 equals $114,000 EAV.

2. What is the maximum 2026 General Homestead Exemption in a county contiguous to Cook County?

  1. $5,000 EAV
  2. $6,000 EAV
  3. $8,000 EAV
  4. $10,000 EAV
Show answer and explanation

Answer: $8,000 EAV

For taxable year 2023 and later, the maximum is $10,000 in Cook, $8,000 in contiguous counties, and $6,000 in all other counties.

3. What is the maximum household income for the Illinois senior assessment freeze in taxable year 2026?

  1. $65,000
  2. $70,000
  3. $75,000
  4. $79,000
Show answer and explanation

Answer: $75,000

Current Section 15-172 sets the 2026 maximum at $75,000. The later limits are $77,000 for 2027 and $79,000 for 2028 and after.

4. Which statement about the Low-Income Senior Citizens Assessment Freeze is correct?

  1. It permanently freezes every local tax rate
  2. It can limit qualifying EAV growth, but the bill can rise
  3. It is available at any age if income is low
  4. It requires no application after the first year
Show answer and explanation

Answer: It can limit qualifying EAV growth, but the bill can rise

The benefit operates through a base EAV. Rates and added improvements can raise taxes, and the applicant must satisfy age, income, residence, and annual filing rules.

5. What must a property owner generally challenge in a county board-of-review assessment appeal?

  1. The assessor's value or assessment uniformity
  2. The state income-tax rate
  3. The transfer-tax stamp design
  4. The school district's election result
Show answer and explanation

Answer: The assessor's value or assessment uniformity

Assessment appeals address the parcel's assessed value, market-value evidence, factual errors, or uniformity. They do not set the local district's levy or tax rate.

Questions students ask about Illinois Real Estate Taxes and Exemptions

How are Illinois real estate taxes calculated?

A standard exam calculation moves from market value to assessed value, applies the state equalization factor to obtain equalized assessed value, subtracts eligible exemptions, and multiplies the remaining taxable EAV by the aggregate local tax rate. In compact form: market value times assessment level times equalization factor, minus exemptions, times the tax rate. Use the assessment level and rate supplied because Cook County classification and preferential assessments can change the starting assumptions.

What is equalized assessed value in Illinois?

Equalized assessed value, or EAV, is assessed value after application of the Illinois Department of Revenue equalization factor. The state equalizes counties so the median assessment level is 33 1/3 percent of fair cash value. Homestead exemptions generally reduce EAV after equalization. EAV is not the same as market value, and an exemption amount stated as an EAV reduction is not deducted directly from the sale price.

Are Illinois property taxes paid in arrears?

Yes. The Illinois property tax cycle generally takes two years. Property is valued as of January 1 in the assessment year, and the resulting bills are paid in the following year. That is why a closing often prorates accrued but not yet billed taxes. The purchase contract and closing instructions control the parties' proration method and adjustment, not a guess that the latest bill equals the current-year final tax.

What is the Illinois General Homestead Exemption amount?

For taxable year 2026, the General Homestead Exemption is an annual EAV reduction based on the increase above the statutory base, up to $10,000 in Cook County, $8,000 in counties contiguous to Cook County, and $6,000 in all other counties. These are maximum EAV reductions, not cash refunds, market-value deductions, or guaranteed reductions in the tax bill by those dollar amounts.

What is the Illinois Senior Citizens Homestead Exemption?

A qualifying resident age 65 or older can receive a maximum EAV reduction of $8,000 in Cook County and counties contiguous to Cook County or $5,000 in all other counties. The applicant generally must occupy the property as a residence, be liable for its real estate taxes, and hold the required record, legal, or equitable interest. Filing and renewal practices can vary by county under the statute.

What is the 2026 Illinois senior freeze income limit?

The enacted maximum household income is $75,000 for taxable year 2026, with the bill payable in 2027. It rises to $77,000 for taxable year 2027 and $79,000 for taxable year 2028 and later under the current statute. The applicant must be at least 65, meet the residence, ownership or qualifying interest, liability, and timing conditions, and file Form PTAX-340 each year.

Does the Illinois senior freeze freeze the property tax bill?

No. It limits qualifying growth in the property's EAV by using a base-year amount. The bill can still increase if local tax rates increase or if added improvements enter the assessment. The name assessment freeze is the clue: it is not a permanent freeze of tax rates, district levies, special assessments, or the final dollars due.

Can a property owner appeal an Illinois tax bill?

The ordinary assessment appeal challenges assessed value, not the local tax rates or the bill itself. An owner can first discuss errors with the assessor, then file a timely written complaint with the county board of review. That written board appeal is generally required before further appeal to the Property Tax Appeal Board or circuit court. Taxes must still be paid while the later appeal is pending.

Is property owned by a charity or church automatically exempt in Illinois?

No. Illinois law focuses on both the statutory ownership category and qualifying use. Religious property must be used exclusively for the specified religious or school-religious purpose and not with a view to profit. Charitable property generally must be actually and exclusively used for charitable or beneficent purposes and not leased or used with a view to profit. The organization applies through the county board of review, and IDOR makes the final administrative decision.

Are these official Illinois real estate exam questions?

No. They are original study questions aligned to Real Estate Taxes and Exemptions in Illinois III.F of the PSI broker outline effective June 24, 2026. The current Illinois Property Tax Code, Illinois Constitution, Illinois Department of Revenue guidance, and June 2026 Property Tax Study were reviewed through August 1, 2026.
