A CP49 means the IRS took some or all of your tax refund and applied it to a tax debt you owe from another year. If the debt is wrong or paid, you can dispute the offset.
A CP49 explains why your refund was smaller than expected — or never arrived: the IRS applied it to a balance you owe for another tax year. The notice shows which year’s debt absorbed the refund and any remainder being sent to you. If the underlying debt is legitimate, the offset simply reduces what you owe. But if you believe the debt was already paid, isn’t yours, or the amount is wrong, dispute it — and if the debt belongs to your spouse, injured-spouse relief may recover your share of a joint refund.
Only if the offset was improper — the debt was paid, incorrect, or not yours — or via injured-spouse relief for a spouse’s debt on a joint return.
Yes, while a balance remains — refunds are applied to outstanding tax debts until they’re resolved.
