What the CP49 is

The IRS says: "We used all or part of your refund to pay a tax debt."

Why you got it

  • You had an unpaid federal tax balance, for example from another tax year.
  • On a joint return, the refund went toward taxes your spouse owes.
A CP49 is about the IRS applying your federal refund to a tax debt. If your Connecticut refund was taken for another debt, that's a separate CT DRS notice. See the CT refund offset summary.

Is there a deadline?

There's no reply date for the CP49 itself. If you disagree, the IRS says: "Call us at the number on your notice and have your paperwork ready." If you still owe after the refund was applied, the IRS points you to paying online or, if you can't pay in full, applying for a payment plan (IRS: Payment plans).

If the IRS used only part of your refund, it says: "You'll receive a check for the remaining amount within 3 weeks unless you owe other taxes or debts we're required to collect."

Is it real? The IRS says it normally contacts you the first time by U.S. mail, and a social media direct message is never from the IRS. If you aren't sure a letter is genuine, check it against your IRS Online Account or IRS: How to know it's really the IRS before you call any number or pay anything.

What to do, step by step

  1. Check which balance the refund was applied to, and compare it with your records and your IRS Online Account.
  2. Still owe? Pay the rest, or apply for a payment plan if you can't pay in full.
  3. Already on a payment plan for that year? The IRS says continue making your payments. If you already made a payment arrangement for the unpaid balance, it says to disregard the notice.
  4. The debt is only your spouse's? If you don't owe the tax, the IRS says you may be able to claim your share of the refund with Form 8379, Injured Spouse Allocation.
  5. Paid the balance in full in the last 21 days? The IRS says if your account shows a credit, it will refund it as long as you owe no other taxes or debts it's required to collect.
  6. Disagree? Call the number on the notice with your tax return or amended return ready.

Common mistakes

  • Assuming the debt is gone. Check whether a balance remains.
  • Not knowing about Form 8379 when the debt belongs only to your spouse.
  • Stopping payment plan payments because a refund was applied.
  • Confusing a CP49 with a state refund offset. They come from different agencies.
