General Information 
What is the Illinois Property Tax Credit?
The Illinois Property Tax Credit is a credit on your individual income tax return (Form IL-1040) equal to 5 percent of Illinois 
Property Tax (real estate tax) you paid on your principal residence. 
You must own your residence in order to take this credit. If you and your spouse each have a principal residence or if 
you had two principal residences during the tax year due to the sale of your home, you may claim the tax paid on both 
residences when figuring this credit. See “What if I sell my house?” for more information. 
Note: For tax years beginning on or after January 1, 2017, the Illinois Property Tax Credit is not allowed if the taxpayer’s 
adjusted gross income for the taxable year exceeds $500,000 for returns with a federal filing status of married filing jointly, or 
$250,000 for all other returns.
Complete Schedule ICR, Illinois Credits, to figure your credit. 
You must write your property number (sometimes called “property index number,” “parcel number,” or “permanent number”) 
on Schedule ICR when claiming an Illinois Property Tax Credit. 
We review the credits you claim and, if necessary, we may ask you to provide additional information to verify your credits. 
See Schedule ICR Instructions for more information.

What property tax may I include when I figure a property tax credit?
You may include the following when figuring your property tax credit:
• Property tax you paid on your principal residence you owned if it is located in Illinois. Generally, you may figure a credit 
  on the property tax you paid on your principal residence for the prior year. For example, you may use the property tax 
  you paid in 2023 for your 2022 residence to figure your property tax credit on your 2023 Form IL-1040.
• Property tax you paid on an adjoining lot to your principal residence, if it is used for residential purposes. 
• Prorated property tax you paid in the year you sold your Illinois residence. 
• Illinois village tax you paid in the tax year. 
• Multi-unit property tax you paid, but only if your principal residence is one of the units. Include only the tax assessed on 
  the unit that is your Illinois residence. 

What may not be included when I figure a property tax credit?
You may not include the following when figuring your property tax credit:
• Property tax assessed on property that is not your principal residence. For example, you may not claim a tax credit on 
  property that you do not live in or consider your principal residence. Examples would be a vacation home, a vacant lot, 
  rental property, property outside of Illinois, and farm land. 
• Property tax assessed on your principal residence that you do not own, even if you paid the tax. For example, if you live 
  with relatives who own the residence and you paid the property tax but you do not own the property, you may not claim a 
  tax credit.  
• Interest, penalties, or fees you paid because your property tax installments were paid late.

                                                                                                 Illinois Property Tax Credit

• Any portion of the property tax due that you did not pay in the tax year. For example, if you did not pay one or both 
  property tax installments on your 2022 taxes due in 2023, you may not include the portion of the 2022 taxes that you did 
  not pay when figuring your property tax credit on your 2023 Form IL-1040. 
• Accountant fees or lawyer fees paid in association with your property tax.
• Homeowner’s association dues or fees paid.
• Property tax paid on separately-deeded condominium parking spaces.
• Property tax paid on an out-of-state home.            

What if I bought a house?
If you bought a house during the current tax year, you may not use the property tax on that house to figure your credit for that 
year. 
For the period of time that the seller lived in the house, the tax was prorated and paid by the seller at the time of closing. The 
tax for the remainder of the year will be assessed to you and paid in the following year. 
For example, you may not use the property tax paid on a house you bought in 2023 on your 2023 return. The seller was liable 
for the tax and will take the property tax credit.
If you bought a house during the previous tax year, you may use the property tax on that house to figure your credit providing 
you figure only that portion of your taxes that pertains to the time you owned and lived at the property during the tax year. For 
example, if you purchased and began living in a house in October 2022, you may use an amount equal to three months of 
your total 2022 property tax to figure your 2023 property tax credit.

What if I built a house?
If you built a house, you may not figure a property tax credit for tax you paid on the vacant lot or the new house before it 
became your principal residence. 
For example, if you built a house in 2022 but did not move in until 2023, you may not include any property tax that you paid 
when figuring your property tax credit for your 2023 Form IL-1040, filed in 2024.

What if I sell my house?
If you sell your house, when figuring your property tax credit you may include 
• the prior year’s property tax you paid and 
• the current year’s prorated tax offset against the sales price at the time of closing.         
For example, if you sold your house during 2023, you may include the 2022 tax and the 2023 prorated tax you paid at the time 
of closing when figuring your 2023 property tax credit on your 2023 Form IL-1040, filed in 2024. 
However, if the house you are selling is vacant for a period of time before it is sold, you may not figure credit for the period of 
time that it was vacant and not your principal residence. 
If you moved into your new house in April 2023 but did not sell your other house until January 2024, you may not include the 
property tax assessed on the old house for the time it was vacant. 

May I include back property tax when I figure my property tax credit?
You may only include back property tax if the tax was paid during the current tax year. However, you may not include interest 
penalties or fees when figuring this credit.

May I include property tax if I am married and filing a separate return?
If you and your spouse filed separate federal returns, each spouse must file a separate Form IL-1040. Each spouse may claim 
part of the property tax. The total may not exceed 100 percent of the total property tax paid. 
If you filed a joint federal return and you are filing a separate Illinois return because one spouse is a resident and one is a 
nonresident or part-year resident, the spouse who is filing as an Illinois resident or part-year resident may figure a property tax 
credit for the tax paid on the principal residence located in Illinois.

May I figure a property tax credit if I live in a mobile home?
If you own a mobile home, that is your principal residence, and the land on which it is located, you may figure a property tax 
credit for the property tax you paid on the land during the tax year. 
You may not figure a credit for mobile home privilege tax.

May I figure a property tax credit if a portion of my residence is used for business?
If a portion of your principal residence is used for business, you may figure a credit on only the portion of your tax that is not 
deductible as a business expense on your federal return. You must subtract federally deductible business expenses, whether 
or not you actually took the federal deduction, before you figure your credit. 
You must subtract this amount on Schedule ICR, Line 4e.

May I figure a property tax credit if I own farm property?
If you own farm property that includes your principal residence, you may figure a property tax credit on only the portion of the 
farm property that is used for your principal residence. You must subtract federally deductible business expenses, whether or 
not you actually took the federal deduction, before you figure your credit. 
You must subtract this amount on Schedule ICR, Line 4e.
If you do not live on the farm property, you may not claim a property tax credit.

May I receive a refund if my property tax credit exceeds the income tax I owe?
If your property tax credit exceeds the income tax you owe, you may not receive a refund for that amount, and you may not 
carry unused credit to other years. Your property tax credit may only reduce the income tax you owe to zero. 

May I figure a property tax credit if I purchase my home under a contract for deed?  
Under a contract for deed, you get immediate possession of the home but do not obtain legal title until the purchase price is 
paid in full. Since you must own the residence, you are unable to claim the property tax credit.
