The CP49 means the IRS took the refund you were expecting and applied it to a balance due in another tax year. Instead of a direct deposit, you get a notice explaining that your overpayment was used to offset a prior or subsequent year's tax debt.
How Offsets Work
Under IRC Section 6402, the IRS has the authority to apply overpayments (refunds) against outstanding tax liabilities. This happens automatically. You don't get a choice. If you filed a 2025 return with a $3,000 refund but you owe $5,000 for 2022, the IRS takes your $3,000 refund and applies it to the 2022 balance. Your new 2022 balance is $2,000 plus whatever interest and penalties have accrued. Your 2025 refund is zero.
If your refund exceeds the balance due, the excess is refunded to you. The CP49 shows the calculation: original refund, amount applied, and remaining refund (if any).
If the Offset Is Wrong
The offset itself is rarely wrong. The IRS's system automatically matches overpayments to outstanding balances. But the underlying balance might be wrong. If you believe you don't actually owe the tax in the year the offset was applied to, you need to address that year's balance separately.
Review the CP49 to identify which tax year received the offset. Then review your records for that year. If the balance was assessed from a Substitute for Return, file your own return for that year. If the balance was from an audit you disagreed with, check whether you still have appeal rights. If the balance was from a return you filed and you've since found an error, file an amended return.
Injured Spouse
If you filed a joint return and your refund was offset to pay your spouse's individual debt (like a prior year balance from before the marriage, student loans, or child support), you may qualify for injured spouse relief. File Form 8379 (Injured Spouse Allocation) to recover your portion of the joint refund.
The Bigger Issue
If you're receiving CP49 notices year after year, your refund is being consumed by unresolved tax debt. The underlying balance needs to be addressed through payment, installment agreement, offer in compromise, or other resolution. Using your annual refund as a makeshift payment plan is the most expensive way to pay because penalties and interest accrue faster than your refund chips away at the balance.
