General Information 

How do I determine my residency?
Under the Federal Veterans Auto and Education Improvement Act of 2022 (Public Law 117-333), a servicemember and the 
servicemember’s spouse may select between one of three residency possibilities for purposes of taxation: (1) the residence 
or domicile of the servicemember, (2) the residence or domicile of the servicemember’s spouse, or (3) the permanent duty 
station of the servicemember. 
 Illinois resident
 You are an Illinois resident if you reside in Illinois or have a legal domicile in Illinois but are absent for a temporary purpose 
 during the tax year. 
 A domicile is the place where you reside and the place where you intend to return after temporary absences. Temporary 
 absences include performing active duty in the armed forces while being stationed outside the state, even for considerable 
 periods of time.
 If you are a member of the armed forces, you are not a resident of Illinois if you are present in Illinois only because of your 
 military assignment. If you are a spouse of a service member, you are not a resident of Illinois if you are a resident of the 
 same state as your spouse and you are present in Illinois only to accompany your spouse on his or her military assignment. 
 For tax years 2018 and after, the Veterans Benefits and Transition Act of 2018 allows a military spouse to elect to use the 
 same residence for tax purposes as the service member even if the spouse is not present in the same state as the service 
 member.  If you are present in Illinois, but have elected to use your service member spouse’s residence for tax purposes, 
 you will not be considered an Illinois resident. In any case, you have the option of remaining a nonresident of Illinois, 
 regardless of how long you are present in the state, but you may choose to establish residency in Illinois. 
 Part-year resident of Illinois
 If you are an Illinois resident for only part of the tax year, you will be considered a part-year resident. For example, if you 
 changed your domicile to a location within Illinois during the tax year, you are a part-year resident of Illinois. 
 For tax years 2018 and after, the Veterans Benefits and Transition Act of 2018 allows a military spouse to elect to use the 
 same residence for tax purposes as the service member even if the spouse is not present in the same state as the service 
 member. This election is effective for the entire taxable year regardless of the date on which the marriage of the spouse and 
 the service member occurred. If you were an Illinois resident for only part of the year, married a service member and then 
 elected to use the service member’s residence for tax purposes during that year, then you are not a part-year resident of 
 Illinois.  You would be considered a resident of the service member’s state of residency for the entire tax year in which the 
 marriage occurred.
 Nonresident of Illinois 
 If you are a resident of another state and come to Illinois only because of a military assignment, you will remain a 
 nonresident of Illinois regardless of how long you are in Illinois unless you elect to become an Illinois resident.

                                                                                                     Illinois Filing Requirements for 
                                                                                                       Military Personnel
  For tax years 2018 and after, the Veterans Benefits and Transition Act of 2018 allows a military spouse to elect to use the 
  same residence for tax purposes as the service member even if the spouse is not present in the same state as the service 
  member.  If you are present in Illinois, but have elected to use your service member spouse’s residence for tax purposes, 
  you will not be considered an Illinois resident regardless of how long you are in Illinois unless you elect to become an Illinois 
  resident.
  If you were domiciled in Illinois at the time you joined the armed forces or elected to change your residence to Illinois after 
  being stationed here, you will remain an Illinois resident as long as you remain in the armed forces, unless you elect to 
  become a resident of another state where you are stationed. 

What are my options for filing a joint return with my spouse?
Spouses who file a joint federal return may elect to file a joint Illinois return. If you file a joint Illinois return, and one spouse is 
an Illinois resident while the other is not, both spouses must be treated as Illinois residents (or as part-year residents for the 
same period).
For tax years 2008 and earlier, if you file a joint federal income tax return, you are required to file a joint Illinois income tax 
return if both you and your spouse are Illinois residents or nonresidents. If one of you is a resident and the other is not, you 
may elect to file separate Illinois returns or to file a joint return on which you are both treated as Illinois residents (or as part-
year residents for the same period). 
Note: For all tax years, you must file separate Illinois returns if you filed separate federal returns.

Must I file an Illinois return?
If you are an Illinois resident or part-year resident, you are required to file an Illinois return if
● you are required to file a federal return, or
●  your Illinois base income is greater than your Illinois exemption allowance. 
If you are a nonresident, you must file an Illinois return if you have earned enough taxable income from Illinois sources to 
have a tax liability (i.e., your Illinois base income from Schedule NR, Nonresident and Part-Year Resident Computation of 
Illinois Tax, is greater than your Illinois exemption allowance from Schedule NR).

How do I report my military pay? 
If you are 
●  an Illinois resident, you must file Form IL-1040, Individual Income Tax Return. Your military pay will generally be included 
  in your federal adjusted gross income (AGI) on Form IL-1040, Line 1.  
●  a part-year resident, you must file Form IL-1040 and Schedule NR. Your military pay will generally be included in the 
  Illinois portion of your AGI on Schedule NR. On Schedule NR, Step 3, Column B, you must include all income earned 
  while a resident regardless of whether such income is earned from Illinois sources, and all income earned from Illinois 
  sources while a nonresident.
●  a nonresident, you are not required to report military pay to Illinois. See “Must I file an Illinois return?” for filing 
  requirements. 
Attach: your military Form W-2 to your Form IL-1040.                                    

What military pay may I subtract? 
You may subtract tax-exempt military pay that is in your AGI, including 
●  pay for duty in the armed forces, including basic training,
● pay for duty as a cadet at the U.S. Military, Air Force, and Coast Guard academies, as a midshipman at the U.S. Naval 
  Academy, or in ROTC, and
●  pay for duty for serving in the U.S. Armed Forces Reserves or a National Guard unit, including a National Guard unit of 
  another state. 
Note: For tax years ending prior to December 31, 2001, you may only subtract compensation paid for active duty. 
Note: For tax years ending prior to December 31, 2007, you may subtract National Guard pay only if you were in the Illinois 
National Guard.  
You may also subtract all income of a person whose federal income tax on that income is forgiven because the person died in 
a combat zone or due to wounds, disease, or injury incurred in a combat zone. 
Note: Residents, part-year residents, and nonresidents, do not subtract military pay or other income that is not included in 
your AGI on Form IL-1040, Line 1.

                                                                                                  Military Personnel
What military pay may I not subtract?
You may not subtract
● military income (such as combat pay) that you excluded from your AGI on Form IL-1040, Line 1; 
● pay you received under the Voluntary Separation Incentive;
● pay you received from the military as a civilian;
● payments you made under the Ready Reserve Mobilization Income Insurance Program; or
● pay for duty as an officer in the Public Health Service. 

Which form should I use to subtract military pay? 
You may subtract military pay on Schedule M, Other Additions and Subtractions for Individuals. 
For more information, see the return instructions for the year you are filing.     
Note: If you are a part-year resident or nonresident, you may subtract tax-exempt military pay on Schedule NR, Step 4, 
Column B if it is included as income in Step 3, Column B.  
Note: If you are an active member of the National Guard and qualify as a Dual Status Technician, attach a copy of your most 
recently issued Standard Form 50 (SF-50), Notification of Personnel Action, along with paper copies of all military W-2s that 
identify that income.  

How do military spouses report their civilian wages? 
Under the Veterans Benefits and Transition Act of 2018, effective for tax years 2018 and after, if
●  you are a nonresident spouse of a service member, and
●  you and your service member spouse have the same domicile and you are in Illinois only to accompany your spouse on 
  his or her military assignment, or
●  you elect to use the same domicile as your service member spouse for the purposes of taxation and you are in Illinois, 
  even if your service member spouse is not located in Illinois,
then your employee wages earned in Illinois are not taxable by Illinois. If you had Illinois Income Tax withheld from your 
wages, you are entitled to a refund if your wages are exempt from Illinois tax under this law. 
To claim your refund you must file Form IL-1040 and Schedule NR and mark the Military Spouse box on Schedule NR. 
To claim exemption from Illinois Income Tax withholding in the future, you must provide your employer with a completed 
Form IL-W-5-NR, Employee’s Statement of Nonresidence in Illinois. 
If you are an Illinois resident, your wages are taxable by Illinois regardless of where you work. 
Note: Under the Federal Veterans Auto and Education Improvement Act of 2022 (Public Law 117-333), a servicemember 
and the servicemember’s spouse may select between one of three residency possibilities for purposes of taxation: (1) 
the residence or domicile of the servicemember, (2) the residence or domicile of the servicemember’s spouse, or (3) the 
permanent duty station of the servicemember. 
Note: The provisions in the Veterans Benefits and Transition Act of 2018 allow that for tax years 2018 and after, the spouse 
of a service member may elect to use the same domicile for purposes of taxation as the service member. This applies for any 
applicable year of the marriage, regardless of the date on which the marriage of the spouse and the service member occurred. 
Note: The provisions in the Veterans Benefits and Transition Act of 2018 that exempt wages from tax apply only to spouses of 
service members, not to the service members themselves. 

What common mistakes should I avoid making?
Illinois does not tax military pay earned by service persons. When completing Schedule M, you may subtract tax-exempt 
military pay that is included as income on Form IL-1040 or Schedule NR.
