No, your pay stubs will show you what you earned in Illinois (IL) vs what you earned in Missouri (MO) based on your move date.
You will file a part year resident return in each state and include only the wages for the residency period in each state. The easiest way to do this is to separate the wages in the federal W-2 entry. Add another state line and then put the appropriate wages in each state line. If you need a State ID you can use the federal EIN without the dashes.
MO Part-Year Resident - An individual domiciled elsewhere prior to moving to Missouri or establishes domicile elsewhere after moving from Missouri. A part-year resident is treated as a nonresident but may determine his tax as if a resident for the entire year.
As a part-year resident, you may take either the Missouri resident credit (MO-CR) or the Missouri income percentage (MO-NRI), whichever is to your benefit. On a joint return, one spouse may take the Missouri income percentage and the other the Missouri resident credit. However, one individual cannot claim both!
This link will provide more details to help you decide how you would like to file for MO.
Illinois (IL) Part year filing requirements:
- 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.
