Understanding Your CP081 Notice

We haven’t received your tax return for a specific tax year. The statute of limitations to claim a refund of your credit or payment for that tax year is about to expire.

What you need to do

  • If you’re required to file this tax return, file immediately. We’ll apply the credit amount shown on this notice to the tax you owe and refund any overpayment to you, if you don’t owe other taxes or obligations.
  • If you’ve already filed this return and it has been over 8 weeks, send us a newly signed copy of your tax return. Be sure to attach copies of all schedules and other documents you included with your previously filed original tax return.
  • If you want the credit transferred to another tax form, tax period or tax identification number, call us at 1-800-829-0115.
  • If you don’t file your tax return or contact us, you’ll lose this credit. The Internal Revenue Code sets strict time limits for refunding or transferring credits.
