What if I did not report, or incorrectly reported, tax for a period covered by amnesty?

1. If you

• failed to file a tax return, complete an original return.
• incorrectly reported liability due on a previously filed return, complete an amended return.

2. Attach any supporting documentation. See the return for detailed instructions.

3. Pay the tax balance for each return in full. The eligible tax liability reported on each return should be paid with a separate check or guaranteed remittance.

4. Your tax return and full payment are due October 1, 2010, through November 8, 2010, to qualify for the 2010 Tax Amnesty program. You may bring the return, any required supporting documentation, and payment to any Illinois Department of Revenue office or mail it to us at the address on the return. Make your payment payable to the “Illinois Department of Revenue.” The postmark must be from the period of October 1, 2010, through November 8, 2010.
