Businesses face strict deadlines when furnishing information returns to employees and contractors. Missing those deadlines can result in costly penalties and compliance risks. To help in exceptional situations, the IRS provides Form 15397, a paper-based extension request form that applies specifically to Form W-2, Form 1099, or other information returns.
This guide explains what businesses need to know about IRS Form 15397, who must file it, which forms it covers, how to complete and submit it, and the consequences of failing to comply.
What is Form 15397?
IRS Form 15397, Extension Request for Certain Information Returns, allows businesses to request additional time (typically up to 30 days) to furnish recipient copies of information returns. Unlike other IRS extensions, this form does not apply automatically. The IRS requires businesses to file Form 15397 on paper with a valid reason for delay, and approval is not guaranteed.
Approval letters will not be issued. The IRS will issue a letter only in instances of an incomplete or denied extension request.
