Paid Preparer's PTIN Requirement

As a result of Public Act 99-0641, for taxable years beginning on or after January 1, 2017, any tax preparer who is paid to prepare Illinois Individual or Business Income Tax returns must enter the preparer tax identification number (PTIN) issued to them by the Internal Revenue Service. The Individual and Business Income Tax forms have been revised to enable paid preparers to provide this information as reported on the tax return.

If the paid preparer is employed with a professional tax preparation firm, the paid preparer must also provide the name, the Federal Employer Identification Number (FEIN), the address, and phone number of the firm.

Electronically filed returns will reject if the PTIN information is missing or incomplete. Paper and 2D barcode returns with missing or incomplete PTIN information will be notified of the PTIN requirement. Failure to comply with this PTIN requirement may incur the issuance of a $50 penalty per return, up to $25,000 per calendar year.
