Frequently Asked Questions — CP21B
What is IRS Notice CP21B?
CP21B confirms that the IRS processed the changes you requested on your tax return (usually via an amended return) and that a refund is on the way.
How long until I get my CP21B refund?
Typically 4-6 weeks after the CP21B notice date. If you don't receive it in 6 weeks, call the IRS or track it at IRS.gov/refunds.
What if the CP21B refund amount is wrong?
If the amount is less than expected, the IRS may have offset part of your refund against another debt. Review the notice for offset details.
Do I need to respond to CP21B?
Generally no — CP21B is a confirmation notice, not a demand. Simply verify the refund amount against your amended return and wait for the check or direct deposit.
