The W-2 deadline, and what late filing costs
Employers must give Form W-2 to employees and file it with the Social Security Administration by January 31, or the next business day. There's no automatic extension. Late or wrong forms carry a penalty for each form, and the amount grows the longer you wait, so file even when you're late.

Quick facts
- Due. January 31 to employees and to SSA, next business day if a weekend
- Also file. Form W-3 goes with paper W-2s, or is built into e-filing
- Fix errors. Corrections go on Form W-2c
What's due, and to whom?
Each employee gets a copy of their W-2 by January 31. You also file the W-2s with the Social Security Administration by the same date, with Form W-3 as the summary. Most businesses e-file through a payroll provider, and if you're filing 10 or more information returns in total, e-filing is generally required.
What goes on a W-2?
Your W-2s should tie back to your four Forms 941 for the year. Check these before you file.
- Employee name and Social Security number, exactly as on their card
- Box 1 wages, which can differ from gross pay because of pre-tax benefits
- Federal, Social Security and Medicare withholding
- Box 12 codes, such as retirement contributions and health coverage for some employers
- State wages and withholding
S-Corp owners with more than 2% of the company have extra rules. Health insurance premiums paid for them go in Box 1. That one trips people up, and it's covered in our reasonable salary guide.
What happens if you're late?
The IRS charges a penalty per form, and it steps up over time. Filing within 30 days of the deadline keeps it at the lowest tier. Filing by August 1 is the middle tier. After that, or not at all, it's the highest. Intentional disregard is worse. The amounts adjust yearly, so check the current information return penalties.
Don't wait for it to be perfect. Late beats never, and it stops the penalty from climbing.
How do you fix a mistake?
File Form W-2c with the Social Security Administration and give the employee a copy. Use Form W-3c as the transmittal. If an employee has lost theirs, you can give a reissued copy marked as such.
What about contractors?
Contractors get a 1099-NEC, not a W-2, and it's due on the same January date. See who needs a 1099. If your payroll runs through a provider, confirm in early January that they'll file for you. Most do, but some plans charge extra.

Can I get an extension on W-2s?
Automatic extensions aren't available. You can request a 30-day extension to file with SSA on Form 8809 in limited situations, and it has to be approved.
What if an employee leaves mid-year?
They still get a W-2 by the January deadline. If they ask for it earlier, you may need to provide it sooner.
Do I send a W-2 to myself as a sole proprietor?
No. Sole proprietors aren't employees of their own business. S-Corp owners who work in the business do get one.
