Employers must send Form W-2 to every employee and file Copy A with the Social Security Administration by January 31 of the year after wages were paid.1Social Security Administration. Deadline Dates to File W-2s For the 2025 tax year, January 31, 2026 falls on a Saturday, so the W-2 deadline for employers shifts to Monday, February 2, 2026.2Internal Revenue Service. Topic No. 154, Form W-2 and Form 1099-R Missing that date triggers per-return penalties that grow the longer the failure goes uncorrected.
The January 31 Deadline
One date covers two obligations: getting W-2s to employees and filing Copy A plus the transmittal Form W-3 with the Social Security Administration.3Internal Revenue Service. Form W-2 and Other Wage Statements Deadline Coming Up for Employers When January 31 lands on a weekend or federal holiday, the deadline moves to the next business day.4Internal Revenue Service. Employment Tax Due Dates
If you mail paper W-2s to employees, the postmark controls. A form postmarked on or before the deadline is timely even if it lands in the mailbox a few days into February. Electronic delivery through a portal or email is allowed only if the employee has consented in a way that shows they can open and read the electronic format.5Internal Revenue Service. General Instructions for Forms W-2 and W-3 Without that consent, you owe a paper copy.
When an Employee Leaves Mid-Year and Asks Early
An employee who separates before year-end can request the W-2 before January. If neither side expects further work that year, you must provide the form within 30 days of the request or within 30 days of the final paycheck, whichever is later.6eCFR. 26 CFR 31.6051-1 – Statements for Employees If there’s a reasonable chance the employee will return during the same year, the ordinary January 31 deadline applies.
Who Has to File Electronically
If you file 10 or more information returns of any type during the year, you must file them electronically. The threshold aggregates across forms, so W-2s, 1099s, and other information returns all count toward the same 10. W-2s go to the Social Security Administration through its Business Services Online (BSO) portal, not through the IRS e-file systems used for other information returns.7Internal Revenue Service. E-File Information Returns
Getting More Time
Two separate extensions exist. One buys time to deliver W-2s to employees. The other buys time to file Copy A with the SSA. They are not interchangeable, and neither is automatic.
Extra Time to Furnish Employee Copies
To extend the employee-delivery deadline, submit Form 15397 to the IRS by the original due date for furnishing the statements.8Internal Revenue Service. Form 15397 – Application for Extension of Time to Furnish Recipient Statements You can file it online or fax it to the Technical Services Operation at 877-477-0572. Approval grants a one-time extension of up to 30 additional days, and the IRS reserves it for situations like natural disasters or system failures.
Extra Time to File With the SSA
For more time to file Copy A with the SSA, submit Form 8809 by January 31 (or the adjusted deadline in a given year). An approved filing extension does not push back the employee-delivery date.9Internal Revenue Service. a href=”https://www.irs.gov/pub/irs-pdf/f8809.pdf” target=”_blank” rel=”noopener”>Form 8809 If you need both, file both forms.
Penalties for Missing the Deadline
Federal penalties fall under two statutes. Section 6721 covers failures in filing with the government, and Section 6722 covers failures in furnishing statements to employees.10Office of the Law Revision Counsel. 26 USC 6721 – Failure to File Correct Information Returns11Office of the Law Revision Counsel. 26 USC 6722 – Failure to Furnish Correct Payee Statements Because a late W-2 typically breaches both obligations, the per-return amount can apply twice for the same form.
Both statutes use a tiered structure. For returns due in 2026, the per-return amounts are:
- Corrected within 30 days: $60 per return
- Corrected after 30 days but by August 1: $130 per return
- Corrected after August 1 or not filed at all: $340 per return
- Intentional disregard: at least $680 per return, with no annual cap12Internal Revenue Service. Information Return Penalties
Annual Caps
For larger employers, annual caps limit total penalties at each tier: $683,000 for failures corrected within 30 days, $2,049,000 for those corrected before August 1, and $4,098,500 for failures corrected after August 1 or not corrected at all.13Internal Revenue Service. 20.1.7 Information Return Penalties
Small businesses, defined as those with average annual gross receipts of $5 million or less over the prior three tax years, get lower caps: $239,000 for 30-day corrections, $683,000 for pre-August 1 corrections, and $1,366,000 for later or uncorrected failures.13Internal Revenue Service. 20.1.7 Information Return Penalties No cap applies to intentional disregard, regardless of size.
Small-Dollar Errors
Not every mistake produces a penalty. If a dollar amount on the W-2 is off by $100 or less, the de minimis error safe harbor generally applies and no penalty is assessed. For a reported amount of tax withheld, the tolerance is tighter: the difference must be $25 or less.14Federal Register. De Minimis Error Safe Harbor Exceptions to Penalties for Failure to File Correct Information Returns or Furnish Correct Payee Statements An employee who receives an incorrect W-2 can still elect to have the error corrected, which removes the safe harbor for that return.
Fixing a W-2 After You File
If you discover an error on a W-2 already filed, whether a wrong Social Security number, an incorrect wage figure, or a misspelled name, file Form W-2c with the SSA as soon as possible. Every W-2c needs a transmittal Form W-3c, even for a name-only or SSN-only correction.15Social Security Administration. Helpful Hints to Forms W-2c/W-3c Filing The corrected form also has to go to the affected employee.5Internal Revenue Service. General Instructions for Forms W-2 and W-3
There is no fixed statutory deadline for a W-2c, but speed matters because the penalty tiers run on the calendar. A correction filed within 30 days sits at the lowest tier; one filed after August 1 sits at the highest. The SSA encourages employers to e-file corrections through Business Services Online.
