If you filed a tax extension for your 2024 return but recently received a CP59SN notice from the IRS claiming you haven’t filed, you’re not alone. We’re seeing reports across the country of taxpayers getting these notices even though they have valid extensions until October 15, 2025.
What’s happening
A CP59SN notice means the IRS thinks you haven’t filed a required return. The problem is that IRS computer systems aren’t properly recognizing filed extensions before generating these notices. Even though you filed correctly and have until October to submit your return, the system is flagging your account as if you missed the April deadline.
The AICPA has been in touch with the IRS about this widespread technical issue.
What you should do
Don’t worry. If you filed a valid extension, you’re in compliance with tax law. The notice is incorrect.
- Verify your extension was filed:Â Check your records for extension acknowledgment. Electronic filers should have a receipt.
- Review your IRS account transcript: Access your transcript online or contact us for help. This shows whether the IRS has your extension on file.
- Consider responding:Â While not required, you may want to respond with a copy of your extension acknowledgment to prevent additional notices.
- Keep monitoring:Â We’re tracking this issue for any official IRS guidance or corrections.
Why this matters
This situation shows why having a tax professional matters. When glitches like this happen, we can quickly identify what’s going on and guide you through the appropriate response. Without that context, an unexpected IRS notice causes unnecessary stress.
Remember: if you filed an extension, you have until October 15 to submit your 2024 return. That deadline hasn’t changed.
