year. 
Step 6: Figure your credit
Line 50 – If you are claiming a credit for tax paid to Iowa, 
Kentucky, Michigan, or Wisconsin, check the box for the appropriate 
state. See “What if I earned income in Iowa, Kentucky, Michigan, or 
Wisconsin?”  under “General Information” for more details. 
Line 51 – Follow the instructions on the form. Enter the total tax 
you paid to all other states (including tax paid to cities or other local 
government) minus all credits allowed, except credits for payments 
you actually made to the other states or payments made on your 
behalf. For full-year residents, you would report 100% of the taxes 
paid.
For a part-year resident, include only the tax on income earned 
or received while an Illinois resident. For example, you and your 
spouse moved to Illinois from Indiana at the beginning of April. 
You worked in Indiana the entire year, earning $30,000 in wages 
evenly throughout the year. Your spouse worked in Indiana the 
entire year, earning $24,000 in wages evenly throughout the year. 
Of your total wage income, $40,500 of such income was earned 
during the period you were an Illinois resident. Your only source of 
income taxable in Indiana is your $54,000 of wage income.  You 
paid $1,000 in income tax to Indiana. The amount of Indiana tax 
you may include on Line 51 is determined as follows:
     
                                          $40,500
                    $1,000  ×                       =  $750.
                                          $54,000 
Note: Do not enter the tax withheld from your Form W-2 on Line 51 
unless you are including tax paid to a city or local government that 
does not require you to file a tax return. See Publication 111 for a 
list of formulas that identify the tax forms, line numbers, additions, 
and subtractions that you must use to compute the other states’ tax. 

Note: Taxes paid to other states should only be included if the 
income tax paid in the other state was for the same income 
included on Form IL-1040, Line 11. If you were a partner or 
shareholder of a pass-through entity which paid income tax to 
another state substantially similar to the income tax imposed 
under Section 201(p) of the Illinois Income Tax Act (IITA), you may 
treat your allocable share of such tax paid by the pass-through 
entity as tax you paid. Your allocable share of the tax paid by the 
pass-through entity is equal to the amount of tax paid to the other 
state by the pass-through entity times the ratio of your share of 
the pass-through entity’s income allocated and apportioned to 
such other state divided by the total amount of the pass-through 
entity’s income allocated and apportioned to such other state. See 
the State Reference Chart on our website for a list of states IDOR 
has determined have a tax substantially similar to the tax imposed 
under Section 201(p) of the IITA.
