IRS notice · CP49

CP49 says your refund was applied to tax debt? Build the offset proof packet first.

A CP49 notice can turn an expected refund into an account-credit or debt-offset question. The useful file connects the notice, tax year, refund amount, prior balance, transcript evidence and any spouse-allocation issue.

Direct answer

IRS CP49 guidance says all or part of a refund was used to pay a tax debt; TAS notes other offsets may involve the Bureau of the Fiscal Service.

Offset

Separate tax debt from other debt.

IRS handles past-due federal tax offsets; non-tax offsets may point to BFS or another agency.

Transcript

Match years before paying again.

A transcript can show whether the refund reduced the correct tax account.

Limit

Joint returns can be sensitive.

Injured spouse, old balances and agency debts should be reviewed before sending extra data.

FAQ

Does CP49 mean my refund disappeared?: It means all or part of the refund was applied to a debt; the notice should explain the application.
Should I pay the same balance again?: Verify the tax year and account first so a payment is not duplicated or misapplied.
Is this tax advice?: No. It is a document-control checklist.
