when are employers required to send w2

Employers are generally required to send out (or make available) your Form W‑2 no later than January 31 following the end of the tax year.
Key deadline (including 2026 timing)
- Federal law says employers must provide W‑2s to employees by January 31 each year (mail, electronic delivery, or in person).
- If January 31 falls on a weekend or federal holiday, the deadline shifts to the next business day.
- For the 2025 tax year (the W‑2 you receive in early 2026), January 31, 2026 falls on a Saturday, so the due date to send W‑2s is February 2, 2026.
“Sent” vs “received”
- Employers meet the requirement as long as they send or make your W‑2 available by the deadline; it may take several days to arrive by mail.
- If mailed on the deadline date to your correct address, they are treated as compliant even if you don’t see it for a week or two.
Filing with SSA (employer side)
- Employers must also file Copy A of each W‑2 with the Social Security Administration by the same deadline (January 31, or the next business day).
What if your W‑2 is late?
- If you don’t have your W‑2 by the end of February , the usual advice is:
- Contact your employer or HR and confirm your mailing address and delivery method.
2. If you still don’t receive it by the end of February, you can contact the IRS; they may reach out to the employer and can provide Form 4852 as a substitute W‑2.

TL;DR: Employers must send your W‑2 by January 31, or the next business day if that date is a weekend/holiday; for the 2025 tax year, that date is February 2, 2026.
