What this notice is about

We haven’t received your federal income tax return.

What you need to do

  • File your personal tax return immediately.

Note: You may disregard this notice if you have already filed. If you have a valid automatic extension of time to file or reside in an area affected by certain federally declared disasters, please file by the applicable extended or postponed due date.

Note: If you received an IRS-issued identity protection personal identification number (IP PIN) due to identity theft, you must include the IP PIN on your tax return, as directed, when you send it to us. If you’re filing a married filing joint return, include each spouse’s IP PIN.

You may want to

  • Check if you need to file a tax return: Make sure you know the rules about who should file.
  • Understand what happens if you’re late: Learn about deadlines for claiming credits or refunds, and what to expect if you file or pay late.
  • Check to make sure your return was not rejected: Review common errors made when filing.
  • Double-check your past returns: Review your records to ensure you’ve filed all your previous tax returns. You can even download copies of old returns to be safe.
  • Make sure you’re withholding enough: Use the Tax Withholding Estimator to check if you’re having enough taxes taken out of your paycheck.
  • Explore payment options if you owe taxes: If you think you might owe more taxes, learn about payment plans, installment agreements, and other options that can help.​​​​​

What can happen if I don’t file?

You may lose your claim to a refund or certain credits. The Internal Revenue Code sets strict time limits to claim those items. If you owe, penalties and interest will continue to accrue until you file and pay in full.

What should I do if I’ve just filed my tax return?

You don't have to do anything if you filed your tax return within the last eight weeks.

What should I do if I didn’t file my tax return, or it’s been more than eight weeks since I filed it?

We show that we didn’t receive your tax return. If you haven’t filed your return, you should file it immediately. If it’s been more than eight weeks since you filed it, check the name, Social Security number (or taxpayer identification number), and tax year on your notice. Make sure they match the name, number, and year on the return. Mail us a signed and dated copy of the tax return.

What if I want to file electronically?

Not all tax preparation services offer this, so you’ll need to look for one that does.

What happens if I can’t pay the full amount I owe when I file my return?

You can request a payment plan with us to pay off your balance over time.

What to do next

  • Write down the date on the letter today.
  • Look the number up on irs.gov yourself. Don’t trust a link or phone number from anyone else.
  • If it says you owe money or proposes changes to your return, take it to a licensed CPA, EA or tax attorney before that date.
