Extension of time to efile 1099 forms
You can request an automatic 30-day filing extension for most Forms 1099 using Form 8809, Application for Extension of Time to File Information Returns. Extensions for Form 1099-NEC are nonautomatic. Form 8809 may be submitted by mail, or eligible extension requests may be submitted electronically through IRIS. Automatic extensions generally require no signature or explanation; nonautomatic extensions, including those for Form 1099-NEC, require a qualifying reason and signature. However, you must file Form 8809 by the due date of the returns in order to get the 30-day extension.
Instructions to apply for form 8809
As soon as you know that a 30-day extension of time to file is needed, file Form 8809.
If submitting a paper Form 8809, follow the form instructions and mail it to the specified IRS address. Faxed requests are not accepted.
You may submit Form 8809 requests by mail regardless of the number of filers or request eligible automatic extensions electronically through IRIS.
