Understanding IRS CP080B notices for nonfilers

If your clients haven't filed a return but have payments or credits sitting on their IRS account, they may soon receive a CP080B notice. For tax professionals, these notices serve as a helpful reminder to reconnect with nonfilers and ensure that clients don't leave funds unclaimed.

What CP080B is and why the IRS sends it

The CP080B notice alerts taxpayers that the IRS has identified one or more payments or credits on their account, but the related tax return hasn't been filed. According to the IRS, these payments may include estimated tax payments, withholding, extension payments or other account credits. Until a return is filed, the IRS can't determine whether the taxpayer is owed a refund or whether the funds should be applied to a balance.

The notice isn't an audit trigger or compliance penalty. It's simply an information notice urging the taxpayer to reconcile the money that belongs to them. View a sample of a CP080-series notice here.

What CP080B means for your clients

Many nonfilers don't understand that the IRS doesn't automatically issue refunds based on payments made during the year. They assume the IRS applies the credit or sends it back. A CP080B notice may be the first time they realize funds are sitting in limbo.

Everyday client situations include:

• Estimated payments made before the taxpayer realized they didn't need to file
• Withholding from part-year employment
• Credits transferred from a spouse's account after a joint return issue
• Extension payments never reconciled to a filed return
• Small business owners who paid estimated taxes but later failed to file a return

In each case, filing the missing return is a straightforward way to release the money.

Key steps tax pros should take when clients receive a CP080B

When a client brings you a CP080B notice, a quick review of their IRS account can help you determine the next steps.

• Confirm whether the return is truly missing. Sometimes a return was filed but rejected, or it may be stuck in an unprocessed status.
• Pull the taxpayer's account transcript and wage and income transcript to verify payments and withholding.
• Identify the refund statute expiration date. If the window to claim a refund is closing, clients need to act quickly.
• Verify whether the taxpayer was required to file. Even if they aren't required to do so based on income, they still need to file to claim a credit or payment refund.
• Prepare and file the missing return securely and as soon as possible.

If the client doesn't respond, remind them that unclaimed credits won't sit on the account forever. Once the statute of limitations expires, the IRS retains the money.

How to help clients avoid future CP080B notices

In most cases, CP080B notices are preventable. Encourage clients to maintain a simple checklist each tax year to ensure payments, withholding and required returns remain aligned.

• Track estimated payments throughout the year and match them to the correct tax year
• Review withholding updates with any job changes
• Confirm that extension payments were actually needed
• File returns even in low-income years if withholding or estimated payments exist
• Use the IRS Online Account to periodically verify what the IRS has on file

Small steps like these help your clients avoid unexpected notices and protect the funds they worked hard to earn.

What tax pros should know about the IRS CP080B page update

The IRS updated its public CP080B page in late 2025. Updated notice webpages are often a sign that the IRS is actively issuing that notice type or preparing for increased distribution. If your clients have outstanding payments on their accounts or have skipped filing in recent years, this is a good time to reconnect and review their information.

Final tips for resolving CP080B notices

CP080B notices can be a valuable opportunity to help clients recover money they might otherwise lose. Once you verify the missing return, confirm payments on the account and prepare the filing, the resolution is usually straightforward.
