General Information
Who must file an Illinois tax return?
If you were
► an Illinois resident, you must file Form IL-1040 if you were required to file a federal income tax return, or you were not required to file a federal income tax return, but your Illinois base income from Line 9 is greater than your Illinois exemption allowance.
► an Illinois resident who worked in Iowa, Kentucky, Michigan, or Wisconsin, you must file Form IL-1040 and include as Illinois income any compensation you received from an employer in these states. Compensation paid to Illinois residents working in these states is taxed by Illinois. Based on reciprocal agreements between Illinois and these states, these states do not tax the compensation of Illinois residents.
If your employer in any of these states withheld that state's tax from your compensation, you may file the correct form with that state to claim a refund. You may not use tax withheld by an employer for these states as a credit on your Illinois return.
► a retired Illinois resident who filed a federal return, you must file Form IL-1040. However, certain types of retirement income (e.g., pension, Social Security, railroad retirement, governmental deferred compensation) may be subtracted from your Illinois income. For more information, see the instructions for Line 5 and Publication 120, Retirement Income.
► a part-year resident, you must file Form IL-1040 and Schedule NR, Nonresident and Part-Year Resident Computation of Illinois Tax, if you earned income from any source while you were a resident, you earned income from Illinois sources while you were not a resident, or you want a refund of any Illinois Income Tax withheld.
► a nonresident, you must file Form IL-1040 and Schedule NR if you earned enough taxable income from Illinois sources to have a tax liability (i.e., your Illinois base income from Schedule NR, Step 5, Line 46, is greater than your Illinois exemption allowance on Schedule NR, Step 5, Line 50), or you want a refund of any Illinois Income Tax withheld in error. You must attach a letter of explanation from your employer.
Note: If you are a nonresident and your only income in Illinois is from one or more partnerships, S corporations, or trusts that withheld enough Illinois Income Tax to pay your liability, you are not required to file a Form IL-1040.
► an Iowa, Kentucky, Michigan, or Wisconsin resident who worked in Illinois, you must file Form IL-1040 and Schedule NR if you received income in Illinois from sources other than wages, salaries, tips, and commissions, or you want a refund of any Illinois Income Tax withheld.
If you received wages, salaries, tips, and commissions from Illinois employers, you are not required to pay Illinois Income Tax on this income. This is based on reciprocal agreements between Illinois and these states.
The reciprocal agreements do not apply to any other income you might have received, such as Illinois lottery winnings and Illinois unemployment income.
► an Illinois resident who was claimed as a dependent on your parents' or another person's return, you must file Form IL-1040 if your Illinois base income from Line 9 is greater than $2,850, or you want a refund of Illinois Income Tax withheld from your pay.
If your parent reported your interest and dividend income through federal Form 8814, Parents' Election to Report Child's Interest and Dividends, do not count that income in determining if you must file your own Form IL-1040.
► the surviving spouse or representative of a deceased taxpayer who was required to file in Illinois, you must file any return required of that taxpayer.
► a student, you are not exempt from tax nor are there special residency provisions for you. However, income, such as certain scholarships or fellowships, that is not taxable under federal income tax law, is also not taxed by Illinois.
► a nonresident alien, you must file Form IL-1040 if your income is taxed under federal income tax law. Note: You must attach a copy of your federal Form 1040-NR, U.S. Nonresident Alien Income Tax Return.
Note: Even if you are not required to file Form IL-1040, you must file to get a refund of
- Illinois Income Tax withheld from your pay,
- estimated tax payments you made, or
- withholding on income passed through to you by a partnership, S Corporation, or trust.
Who is an Illinois resident?
You are an Illinois resident if you were domiciled in Illinois for the entire tax year. Your domicile is the place where you reside and the place where you intend to return after temporary absences. Temporary absences may include duty in the U.S. Armed Forces, residence in a foreign country, out-of-state residence as a student, or out-of-state residence during the winter or summer.
If you filed a joint federal return and one spouse is an Illinois resident while the other spouse is a nonresident or a part-year resident, you may file separate Illinois returns. If you file a joint Illinois return, you will both be taxed as residents.
What is Illinois income?
Your Illinois income includes the adjusted gross income (AGI) amount figured on your federal return, plus any additional income that must be added to your AGI. Note: Some of your income may be subtracted when figuring your Illinois base income. For more information, see the Step-by-Step Instructions. You should follow the federal law concerning passive activity income and losses. You are not allowed to refigure your federal passive activity losses.
Also, federal law will govern the taxation of income from community property sources in the case of spouses who file joint federal returns and who file separate Illinois returns.
How may I file?
File your individual income tax return electronically by using
- MyTax Illinois, available on our website for free,
- a tax professional, or
- tax preparation software.
Almost all taxpayers can file electronically. Visit mytax.illinois.gov or see your tax professional. If you do not wish to file electronically, you may use the paper Form IL-1040.
When must I file?
Your Illinois filing period is the same as your federal filing period. We will assume that you are filing your Form IL-1040 for calendar year 2025 unless you are filing for a fiscal year and indicate a different filing period in the space provided at the top of the return. The due date for calendar year filers is April 15. If this date falls on a weekend or holiday, then the due date is the next business day after the weekend or holiday.
The due date to file and pay for 2025 is April 15, 2026.
We grant an automatic six-month extension of time to file your return. If you receive a federal extension of more than six months, you are automatically allowed that extension for Illinois. These extensions do not grant you an extension of time to pay any tax you owe. If you determine that you will owe tax, you must use Form IL-505-I, Automatic Extension Payment for Individuals, to pay any tax you owe to avoid penalty and interest on tax not paid by April 15, 2026.
The extended due date to file is October 15, 2026.
Should I round?
You must round cents to whole dollars on Form IL-1040 and most schedules, as directed. To round you must
- drop amounts under 50 cents and
- increase amounts of 50 to 99 cents to the next dollar.
For example, $1.49 becomes $1 and $2.50 becomes $3.
If you have to add two or more amounts to figure the amount to enter on a line, include cents when adding the amounts and round only the total.
Will I owe penalties and interest?
You will owe
- a late-filing penalty if you do not file a return that we can process by the extended due date.
- a late-payment penalty for tax not paid by the original due date of the return.
- a late-payment penalty for underpayment of estimated tax if you were required to make estimated tax payments and failed to pay the required amount by the payment due dates.
- a bad check penalty if your remittance is not honored by your financial institution.
- a cost of collection fee if you do not pay the amount you owe within 30 days of the date printed on any IDOR-2-BILL, Final Notice of Tax Due for Form IL-1040, Individual Income Tax Return, you receive.
General Information
General Information
- a frivolous return penalty if you file a return that does not contain information necessary to figure the correct tax or shows a substantially incorrect tax, because you are taking a frivolous position or are trying to delay or interfere with collection of the tax.
- interest on unpaid tax from the day after the original due date of your return through the date you pay the tax.
We will bill you for penalties and interest. For more information about penalties and interest, see Publication 103, Penalties and Interest for Illinois Taxes.
What if I cannot pay?
If you cannot pay the tax you owe but you can complete your return on time, file your return by the due date without the payment. This will prevent a late-filing penalty from being assessed. You will, however, owe a late-payment penalty and interest on any tax you owe after the original due date, even if you have an extension of time to file.
You have the option to pay the amount you owe electronically by using our website or by credit card. See the instructions for Line 41.
When must I file an amended return?
Do not file another Form IL-1040 to make changes to a previously filed Form IL-1040. You must file Form IL-1040-X, Amended Individual Income Tax Return, if
- you discover that you made an error on your Illinois return after it was filed, or
- your federal return has been adjusted either by the Internal Revenue Service (IRS) or on a federal Form 1040X, Amended U.S. Individual Income Tax Return, you filed; the change affects your Illinois income, additions, subtractions, exemptions, or credits; and the change is final.
Note: If the federal change results in a refund, do not file Form IL-1040-X until you receive notification that your change has been accepted by the IRS.
For more information, see Form IL-1040-X and Instructions. What if I have household employees?
You may use Form IL-1040 to pay your household employees' Illinois withholding. For more details on how to pay withholding for your employees, see the instructions for Line 20.
What if I change my address?
If you change your address after you file, visit our website or call us to tell us your new address and the date you moved.
What if I am an injured spouse?
If you are married and you filed a joint federal return with your spouse and you are an injured spouse (e.g., your spouse owes a liability, for which you are not responsible, to a government agency), you may elect to file separate Illinois returns using the "married filing separately" filing status. You may make this election up until the extended due date of your return. After the extended due date of the return, the election is irrevocable.
Note:
If you file a joint Illinois return, we may take the entire refund to pay your spouse's liability.
What if I participated in a potentially abusive tax avoidance transaction?
If you participated in a reportable transaction, including a "listed transaction," during this tax year and were required to disclose that to the IRS, you are also required to disclose that information to Illinois.
You must send us two copies of the form you used to disclose the transaction to the IRS. You must
- attach one copy to your tax return, and
- mail a second copy to the Illinois Department of Revenue, P.O. Box 19029, Springfield, Illinois 62794-9029.
Note: Employee benefit plans and other subtractions allowed on Form IL-1040, Lines 5 through 7, are not reportable transactions. For more information, contact the IRS or your tax professional.

In general, you should use the same filing status as on your federal return. However,
- if you file a federal return as a "Qualifying Surviving Spouse (QSS)," choose "Widowed" for your filing status.
- if you file a joint federal return and you are an injured spouse (your spouse owes a liability, for which you are not responsible, to a government agency), you should file separate Illinois returns using the "married filing separately" filing status.
Do not recalculate any items on your federal return. Instead, you must divide each item of income and deduction shown on your joint federal return between your separate Illinois returns following the Allocation Worksheet on Page 17.
You may choose to file separately as an injured spouse only until the extended due date of the return, and once you choose a filing status, the decision is irrevocable for the tax year.
Note: If you choose to file a joint Illinois return, we may take the entire refund to pay your spouse's liability.
- If you file a joint federal return and one spouse is a full-year Illinois resident while the other is a part-year resident or a nonresident (e.g., military personnel), file "married filing separately." Do not recalculate any items on your federal return.

- you used or consumed these items in Illinois, and
- when you purchased the items you either did not pay any sales tax to the seller, or paid sales tax at less than Illinois' Use Tax rates of 6.25 percent for general merchandise and 1 percent for food and drugs.
For example, if you purchased
- a computer over the internet for use in Illinois and paid no sales tax, you owe 6.25 percent Illinois Use Tax.
- jewelry while vacationing in Georgia upon which you paid 4 percent sales tax and which you brought back to Illinois, you will owe Illinois Use Tax on the 2.25 percent difference in tax rates.
- cheese by mail order from a company in Wisconsin and paid no sales tax, you owe 1 percent Illinois Use Tax.
How do I determine the Illinois Use Tax I owe?
To determine the Illinois Use Tax you owe, check your records to see if you were charged tax on internet, mail order, or other out-of-state purchases and use the UT Worksheet to calculate your tax.
If your records are incomplete and you had
- major purchases, add the actual cost of your major purchases to the estimated cost of any other purchases you made during the year. Enter the total on Lines 1a or 2a of the UT Worksheet to calculate the use tax you owe.
- no major purchases, use the UT Table to help you estimate the use tax you owe.
Enter the Illinois Use Tax from the UT Worksheet or UT Table on Form IL-1040, Line 21.
Note: If we find that you owe additional tax, we may assess the additional tax plus applicable penalties and interest. We conduct routine audits based on information received from third parties, including the U.S. Customs Service and other states.

Transactions subject to the surcharge means sales and exchanges of
- capital assets,
- depreciable business property,
- real property used in the trade or business, and
- Section 197 intangibles of an organization registrant.
What is the Compassionate Use of Medical Cannabis Program
Act surcharge?
For each taxable year beginning or ending during the Compassionate Use of Medical Cannabis Program, a surcharge is imposed on all taxpayers on income arising from the transactions subject to the surcharge of an organization registrant under the Compassionate Use of Medical Cannabis Program Act.
The amount of the surcharge is equal to the amount of federal income tax liability for the taxable year attributable to the transactions subject to the surcharge.
To whom does the surcharge apply?
The surcharge is imposed on any taxpayer who incurs a federal income tax liability on the income realized on a "transaction subject to the surcharge," including individuals and other taxpayers who are not themselves the "organization registrant" that engaged in the transaction.
A line has been included on Schedule K-1-P, Partner's or Shareholder's Share of Income, Deductions, Credits, and Recapture, and Schedule K-1-T, Beneficiary's Share of Income and Deductions, to identify the amount of federal income attributable to transactions subject to the surcharge that was passed through to you on federal Schedule K-1.

What is the Sale of Assets by Gaming Licensees surcharge?
For each taxable year beginning in 2019 through 2027, the amount of the surcharge is equal to the amount of federal income tax liability attributable to those sales and exchanges.
To whom does the Sale of Assets by Gaming Licensees surcharge apply?
The surcharge is imposed on any taxpayer who incurs a federal income tax liability on the income realized on a "transaction subject to the surcharge," including individuals and other taxpayers who are not themselves the "organization licensee" that engaged in the transaction.

If you
- have a tax liability greater than $1,000 after subtracting your withholding, pass-through withholding payments, and credits, or
- were required to make estimated tax payments and failed to pay the required amount by the payment due dates, you may owe a late-payment penalty for underpayment of estimated tax.
See Form IL-2210 for details.
Note: If you are 65 years of age or older and you permanently live in a nursing home, or if at least two-thirds of your federal gross income is from farming, you are not required to make estimated tax payments and are not subject to a late-payment penalty for underpayment of estimated tax.
Note: You do not owe a late-payment penalty for underpayment of estimated tax if you were not required to file a Form IL-1040 last year.
Note: If you owe this penalty, you should consider increasing your withholding or the amount of your estimated tax payments. For more information, see the Form IL-1040-ES Instructions, Publication 105, and Form IL-W-4, Employee's Illinois Withholding Allowance Certificate.
Let us figure your penalty and bill you
Figuring your own penalty can be difficult. We encourage you to file your Form IL-1040 and pay the tax you owe without including any penalty. If you owe this penalty, we will figure the amount and bill you.
Note: If you annualized your income, you must complete Form IL-2210. See the instructions for Line 34c.
Line 34a
Farmers
Check the box if at least two-thirds of your total federal gross income came from farming. Total federal gross income includes your spouse's income if your filing status is "married filing jointly."
Federal gross income from farming
"Federal gross income from farming" is the amount of income you received from your participation in the production of crops, fruits, fish, livestock (used for draft, breeding, or dairy purposes), or other agricultural products. This includes income from the operation of a stock, dairy, poultry, fruit, or truck farm, plantation, ranch, nursery, range, or orchard - regardless of whether the operation is organized as a sole proprietorship, a partnership, an S corporation, or a trust. "Federal gross income from farming" also includes a share of crops produced in exchange for the use of the land. See IRS Publication 225, Farmer's Tax Guide.
"Federal gross income from farming" does not include payments from the sale of farmland and farm equipment, nor does it include income received by a custom grain harvester who performs grain harvesting and hauling services on farms he or she does not own, rent, or lease. It also does not include the wages of a farm employee or cash rent.

Amount of overpayment to be credited forward
Subtract Line 38 from Line 37. This is the amount of overpayment you elect to be applied against your estimated tax obligation.
Note: We will reduce any credit to your estimated tax by the amount of any outstanding tax, penalties, and interest you owe. If your credit is reduced, you may owe a late-payment penalty for underpayment of estimated tax. For more information, see Form IL-1040-ES.
To which tax period will my credit apply?
We will apply your credit to the tax period for which estimated payments currently are due based on the date you file this 2025 return.
Example 1: You file your 2025 calendar year return on October 6, 2026, which is before the last estimated tax due date for 2026 (January 15, 2027, for calendar year filers). You request your $500 overpayment be applied against your estimated tax. We will apply $500 to your 2026 estimated tax.
Example 2: You file your 2025 calendar year return on February 3, 2027, which is after the last estimated tax due date for 2026 (January 15, 2027, for calendar year filers). You request your $500 overpayment be applied against your estimated tax. We will apply $500 to your 2027 estimated tax.
Step 11 Refund or amount you owe
Lines 40-41
With what date will my credit apply against my estimated tax?
If your 2025 return was filed
- on or before the extended due date of your return
(October 15, 2026, for calendar year filers), your credit is considered to be paid on the original due date of your 2025 return (April 15, 2026, for calendar year filers).
Example 1: You file your 2025 calendar year return on or before the extended due date of your return requesting $500 be applied against estimated tax. All of your payments are made before the original due date of your return. Your credit of $500 will be considered to be paid on April 15, 2026.
However, if all or a portion of your overpayment results from payments made after the original due date of your 2025 return, that portion of your credit is considered to be paid on the date you made the payment.
Example 2: You file your 2025 calendar year return on or before the extended due date of your return requesting $500 be applied against estimated tax. Your overpayment includes payments of $400 you made before the original due date of your return, and a $100 payment you made on June 1, 2026. Your credit of $400 will be considered to be paid on April 15, 2026. The remaining $100 credit will be considered to be paid on June 1, 2026.
- after the extended due date of your return, your credit is considered to be paid on the date you filed the return on which you made the election. Example 3: You file your 2025 calendar year return on December 1, 2026, requesting $500 be applied against estimated tax. Your credit of $500 will be considered to be paid on December 1, 2026, because you filed your return after the extended due date of your 2025 calendar year return.
May I apply my credit to a different tax period?
Yes. If you wish to apply your credit to a tax period other than the one described above, you must submit a separate request in writing to:
