Before You Leave Illinois
File a part-year IL-1040 with Schedule NR
For the year you move, file Form IL-1040 with Schedule NR. Illinois taxes all income you received while you lived here. After you move, it taxes only income from Illinois sources. On Schedule NR, enter the dates you lived in Illinois and in your new state. If your new state also taxed income you earned as an Illinois resident, you may get a credit on Schedule CR.

After you move, keep reporting net income from real estate located in Illinois on Schedule NR. If you sell Illinois real estate, report that gain too. Illinois does not tax a nonresident on nonbusiness gains from intangibles, such as stock.

You can get a homestead exemption only on your main residence. If the house is no longer your main residence, apply to the Cook County Assessor to remove the exemption. The Assessor audits exemptions. If you kept one you were not entitled to, it bills the tax, interest, and penalties. It can also put a lien on the property.

If you sell your vehicle, tell the Secretary of State. Do it at a DMV, or mail the Seller's Report of Sale form. Until the record changes, emissions test notices keep coming to you.

Your new state may ask for proof that your Illinois license is valid. Illinois stopped issuing clearance letters in 1997. Other states check your record through the Problem Driver Pointer System. If your new state still wants written proof, order a copy of your Illinois driving record.
