Notification of unreported federal changes

If the IRS made changes to your client’s federal return that impact their New York State personal income tax return, your client must report those changes to the department within 90 days of the final IRS determination by filing an amended return.

If your client did not file an amended tax return, they may receive a bill.

  • If your client agrees with the bill, they can simply pay using the payment coupon included, or pay online using Online Services or Quick Pay. They do not need to file an amended return.
  • If your client disagrees with the bill, respond with any applicable documentation by the date on the first page of the bill. Submit the response online, by mail, or by fax. Include the assessment number on each piece of correspondence.
