On the paper
Find the tax year the refund was applied to, the amount applied, and any remaining refund or remaining balance the notice shows.
Look at whether the offset cleared the older year or only reduced it. A CP49 that leaves the older year with a balance means the collection notices for that year continue, and the next one in the sequence will arrive with the reduced figure rather than stopping.
Find the date printed on your notice or letter. The paper notice and the current official IRS instructions control, even where this page differs.
Where this notice comes from
The IRS applies an overpayment to other federal tax liabilities before releasing a refund. That is why a return can be correct and the refund still not arrive.
Offsets to non-tax debts, such as child support or a federal student loan, are handled by a different program and produce a notice from that program rather than a CP49.
A married couple filing jointly where only one spouse owes the older tax has a separate route for the other spouse's share, and it has its own form and its own standards.
The notice is also a record worth keeping. It is the document that shows when the older year was paid and by how much, which matters if a later notice for that year arrives with a figure that does not account for the offset.
General next steps
- Confirm the tax year that received the refund is a year you actually owe.
- If the older balance is now paid in full, keep this notice as the record of that payment.
- If you disagree with the offset, use the contact instructions on the notice.
Timing
The IRS page for CP49, checked September 10, 2026, gives no general period and asks you to contact it promptly if you disagree. The date printed on the notice controls; do not calculate a deadline from this page.
What CP49 does not mean
An offset is not a penalty and not a collection action in the levy sense. It is the IRS applying money it already holds to a balance on its own books. It also does not mean every debt is resolved, because a refund can be smaller than the balance it was applied to.
What this page cannot tell you
This page cannot tell you whether the older balance was correct or whether a share of the refund can be recovered.

Common questions
The debt belongs to my spouse, not me.
The IRS has a separate process for a spouse's share of a joint refund applied to the other spouse's separate debt. It is a distinct claim with its own form and standards.
Does the offset stop the collection notices for the older year?
Only if it paid that year in full. A partial offset reduces the balance, and the notice sequence for that year continues with the smaller figure.
Does the offset change what I owe overall?
No. The same money moved from one column to another. The refund you expected was applied to a balance you already had, so the total the IRS shows across your years drops by the amount applied and by nothing more.
Can I choose which year the refund pays?
Not for an offset. The IRS applies an overpayment to outstanding federal tax liabilities under its own rules. Designation is available for voluntary payments, not for offsets.
