What Form 15397 does
Form 15397 requests a one-time extension of up to 30 days to furnish certain information-return statements to recipients. It does not extend the deadline to file information returns with the IRS; Form 8809 serves that different purpose and cannot be faxed.
Check the form before faxing
- Check that the statements you need to furnish are among the form types listed on the current Form 15397 and explain why more time is needed.
- Complete and sign the form. File it no later than the due date for the recipient statements; if several statement types have different due dates, the earliest one governs a combined request.
- Choose the IRS online submission or fax. Do not send the same extension request more than once, because the form warns duplicates can delay or prevent processing.

Questions about Form 15397
Does Form 15397 extend the deadline to file Forms 1099 with the IRS?
No. It concerns recipient statements. IRS filing extensions are a separate process; the IRS says Form 8809 extension requests sent by fax are not accepted.
Will the IRS mail an approval letter?
The current form says no approval letter is issued for an approved request. The IRS sends a letter if the request is incomplete or denied.
