General Information
Who must le an Illinois tax return?
If you were
► an Illinois resident, you must le Form IL-1040 if
you were required to le a federal income tax return, or
you were not required to le 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 le 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 le 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 led a federal return, you must le 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 le 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 le 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 le a Form IL-1040.
► an Iowa, Kentucky, Michigan, or Wisconsin resident who worked in Illinois, you must le 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 le Form IL-1040 if
your Illinois base income from Line 9 is greater than $2,425, 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 le your own Form IL-1040.
► the surviving spouse or representative of a deceased taxpayer who was required to le in Illinois, you must le 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 le Form IL-1040 if your income is taxed under federal income tax law. Note: You must attach a copy of
your federal Form 1040NR, U.S. Nonresident Alien Income Tax Return.
Note: Even if you are not required to le Form IL‑1040, you must le 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 led 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 le separate Illinois returns. If you le 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 gured on your federal return, plus any additional income that must
be added to your AGI. Note: Some of your income may be subtracted when guring 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 regure your federal passive
activity losses.
Also, federal law will govern the taxation of income from community property sources in the case of spouses who le joint federal returns
and who le separate Illinois returns.
How may I le?
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 le electronically. Visit
mytax.illinois.gov or see your tax professional. If you do not wish to le electronically, you
may use the paper Form IL-1040.
When must I le?
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
2023 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 lers 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 le and pay for 2023 is April 15, 2024.
We grant an automatic six-month extension of time to le 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, 2024.
The extended due date to le is October 15, 2024.
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 gure 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‑ling penalty if you do not le 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 nancial 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

tax.illinois.gov
General Information
• a frivolous return penalty if you le a return that does not contain information necessary to gure 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, le your return by the due date without the payment. This will
prevent a late-ling 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 le.
You have the option to pay the amount you owe electronically by using our website or by credit card. See the instructions for Line 40.
When must I le an amended return?
Do not le another Form IL-1040 to make changes to a previously led Form IL-1040. You must le Form IL-1040-X, Amended Individual
Income Tax Return, if
• you discover that you made an error on your Illinois return after it was led, 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 led; the change aects your Illinois income, additions, subtractions, exemptions, or credits; and the change is
nal.
Note: If the federal change results in a refund, do not le Form IL-1040-X until you receive notication 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 le, 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 led 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 le separate Illinois returns using the “married ling separately”
ling status. You may make this election up until the extended due date of your return, and once the election is made, it is irrevocable for the
tax year.
Note:
If you le 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, Springeld, Illinois 62794-9029.
Note: Employee benet plans and other subtractions allowed on Form IL-1040, Lines 5 through 7, are not reportable transactions. For more

What is Illinois Use Tax?
Illinois Use Tax is a form of sales tax that you, as the purchaser, owe
on items that you buy for use in Illinois. If the seller does not collect
this tax from you, you must pay the tax to the Illinois Department of
Revenue (IDOR). The most common purchases on which the seller
does not collect Illinois Use Tax are those made through the internet,
from a mail order catalog, or when traveling outside Illinois.
When must I pay Illinois Use Tax to IDOR?
You must pay Illinois Use Tax to IDOR if
• the items you bought are taxable in Illinois,
• 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 dierence 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 nd 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.

October 6, 2024, which is before the last estimated tax due date for
2024 (January 15, 2025, for calendar year lers). You request your
$500 overpayment be applied against your estimated tax. We will
apply $500 to your 2024 estimated tax.
Example 2: You le your 2023 calendar year return on
February 3, 2025, which is after the last estimated tax due date for
2024 (January 15, 2025, for calendar year lers). You request your

With what date will my credit apply against my estimated
tax?
If your 2023 return was led
• on or before the extended due date of your return
(October 15, 2024, for calendar year lers), your credit is
considered to be paid on the original due date of your 2023
return (April 15, 2024, for calendar year lers).
Example 1: You le your 2023 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, 2024.
However, if all or a portion of your overpayment results from
payments made after the original due date of your 2023 return,
that portion of your credit is considered to be paid on the date
you made the payment.
Example 2: You le your 2023 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, 2024. Your credit of $400 will be considered to be
paid on April 15, 2024. The remaining $100 credit will be
considered to be paid on June 1, 2024.
• after the extended due date of your return, your credit is
considered to be paid on the date you led the return on which
you made the election.
Example 3: You le your 2023 calendar year
return on December 1, 2024, requesting $500 be applied
against estimated tax. Your credit of $500 will be considered
to be paid on December 1, 2024, because you led your
return after the extended due date of your 2023 calendar
year return.
