If your Offer in Compromise has been approved, you need to make sure the IRS does not revoke your Offer. At all costs, make sure that you:
•File your taxes on-time for the next five years.
•If you cannot file by April 15th, request an automatic extension. Definitely file your taxes by the extension deadline.
•Pay your taxes on-time. If you owe, your taxes must be paid in full by April 15th. Make estimated payments or extension payments to make sure you don't have a balance due.
If the IRS revokes your Offer in Compromise, they will reinstate the full amount of your tax liability, add on penalties and interest, and begin aggressive collection efforts.
