What CP39 means

CP39 explains that a refund was taken to pay tax you owed. What makes it different from other offset notices is that the refund may have been your spouse's or a former spouse's, not your own. The notice shows how much was applied and any balance left. See refund offsets for how offsets work.

If you cannot pay what is left

The IRS points to three options: a payment plan, an offer in compromise, or a temporary delay of collection. See installment agreements to compare payment plans.
