Form W-3 (Transmittal of Wage and Tax Statements)

The Form W-3 exists so the Social Security Administration can reconcile individual W-2s against employer-level totals. It reports total wages, Social Security and Medicare wages and taxes, federal income tax withheld, dependent care and deferred compensation amounts, the employer's EIN and establishment information, and the kind of payer and kind of employer. The deadline matches the January 31 W-2 deadline for both SSA filing and employee statements.

Because the electronic filing threshold now counts ten information returns of all types combined, most employers file through Business Services Online, where totals are generated automatically and no separate W-3 is submitted. Paper filers must use the scannable official form; printing a downloaded copy and mailing it can draw a penalty.

The reconciliation that catches employers is the comparison between W-3 totals and the four quarterly Forms 941. SSA and the IRS match them, and a mismatch generates a notice asking you to explain the difference. Common causes are third-party sick pay, a fringe benefit added at year end, or a 941-X filed after the W-2s went out with no corresponding W-2c and W-3c. Reconcile quarterly rather than waiting until January.

Frequently asked questions

Do employers filing electronically still submit a W-3?

Generally no. Filing through Business Services Online generates the employer-level totals automatically, so no separate transmittal is sent. Because the electronic filing threshold counts ten information returns of all types combined, most employers end up filing electronically whether or not that was the original plan.

What deadline applies to the W-3?

The end of January, matching the W-2 deadline for both the SSA filing and the statements furnished to employees. Paper filers also have to use the scannable official form. Printing a downloaded copy and mailing it can draw a penalty on its own, entirely separate from anything to do with timing.

Why would W-3 totals disagree with the quarterly returns?

Usually third-party sick pay, a fringe benefit added at year end, or a corrected quarterly return filed after the W-2s went out without matching corrected wage statements. SSA and the IRS compare the two sets of totals and send a notice asking for an explanation. Reconciling each quarter avoids the January scramble.
