An Illinois resident who was employed in Iowa, Kentucky, Michigan, or Wisconsin, must file Form IL-1040 and include all compensation you received from an employer in these states. Compensation paid to Illinois residents working in these states is taxable to Illinois. While you were a resident of Illinois, you are covered by a reciprocal agreement between the reciprocal state and Illinois and are not to be taxed by the other state on your wages.
If your employer withheld tax for the other state or you paid tax to these states on your compensation, you must claim a refund from that state. You may not claim a credit on Schedule CR for that tax withheld by the employer. You must file the appropriate forms with that state to receive a refund of tax withheld in error.
The credit for taxes paid to another state is automatically calculated in your account when you add a Nonresident state return to your already created Resident Illinois return.
If you qualify for the reciprocal agreement, you will need to remove the automatic calculation by logging into your account and go to the State Section Illinois Resident Return Edit Enter Myself Credits Credit for Taxes Paid to Another State Are you claiming credit for taxes paid to (Iowa, Kentucky, Michigan or Wisconsin). Select Yes for the correct state. The Illinois return will no longer calculate the credit. You will now need to go to the Nonresident return and apply the credit to that return.

NOTE: The nonresident returns will refund all or most of the taxes withheld. The resident return will calculate an amount owed (usually).
The reciprocal agreements do not prohibit subdivisions of these states from imposing a tax on your compensation. For example, if you were subject to tax by a city in Kentucky while you were an Illinois resident, you may claim a credit for that local tax.
In addition, because of differences in state laws, you may be considered a resident by one of these states and required to pay their income taxes, even though you are an Illinois resident under Illinois law. In that case, you may claim a credit for the tax paid.
