IRS Notice CP518

You must file your tax return

Many situations can lead to an IRS notice about an unfiled tax return. Perhaps your return hasn't been processed yet, and the IRS sent the notice in error. Maybe something prevented you from filing your return this year. Whatever the case, H&R Block will help you get the issue straightened out and make sure the problem doesn't get worse.

What happened?

  1. IRS never received a tax return from you for the year specified.
