IRS Paper 1099 filing deadline

IRS Paper 1099 Deadline Moves to March 2, 2026

Published: February 25, 2026

IRS paper 1099 filing deadline March 2 2026 Form 1096 weekend adjustment

The IRS paper filing deadline for Form 1096 and certain paper Forms 1099 shifts to Monday, March 2, 2026 because February 28 falls on a Saturday. If you are still preparing paper filings this week, you now have one additional business day.

Important: Form 1099-NEC is not included in this weekend adjustment.

What This Means for AP

Applies to paper filers only.
Ensure Form 1096 totals match all paper 1099s included.
Mail early enough to secure a March 2 postmark.
Late filing penalties can reach $310 per form (depending on timing and circumstances).

APPG Insight: A one-day shift can still impact mailing workflows, year-end documentation, and close checklists. Confirm your filing method before submission.
