What you should do?
Read your letter carefully. The letter details the terms and conditions including amount due, due date, and mailing address to mail payments. The letter also provides the criteria you need to follow to keep your offer intact.
What can you expect next?
Once you make your final payment, the IRS will mail you an OIC Final Payment Letter.
After this point, you are required to stay in compliance with the offer terms for the next five years. This includes filing on time and not incurring or owing new tax balances. Failure to comply with the Offer terms will result in default. The IRS will reverse the removal of all back taxes for noncompliance with the Offer terms.
This letter is considered a tax bill. The IRS asks that you pay the balance due in full. You do have options.
