What is Form W-3?
The transmittal cover sheet that accompanies paper W-2 forms sent to the SSA
Form W-3 (Transmittal of Wage and Tax Statements) is a summary form that employers use to transmit Copy A of their W-2 forms to the Social Security Administration (SSA) — not the IRS. It acts as a cover sheet that totals up every employee's wages and taxes reported across all the attached W-2s, allowing the SSA to verify your payroll data matches what employees report on their tax returns.
Critical rule: Form W-3 is only required when you file W-2 forms on paper. If you file electronically through SSA Business Services Online or payroll software, the system generates transmittal data automatically — no separate W-3 form is needed or accepted.
Who Must File Form W-3?
Filing requirements for employers submitting paper W-2 forms
You Must File W-3 If:
- You are an employer with employees (not just contractors)
- You are filing paper W-2 Copy A forms with the SSA
- You paid wages subject to federal income tax, FICA, or Medicare withholding
- You are a household employer (nannies, housekeepers, etc.)
- You are a non-profit, LLC, S-Corp, or C-Corp with payroll
- You are filing corrected W-2c forms (use Form W-3c instead)
You Don't File W-3 If:
- You file W-2s electronically via SSA Business Services Online
- You use payroll software (QuickBooks, Gusto, ADP) that e-files for you
- You only have independent contractors (use 1099-NEC instead)
- You had no employees during the tax year
- You are an employee receiving a W-2 (only employers file)
- You have 10 or more W-2s — e-file is required, no W-3 needed
W-3 vs. W-2: Understanding the Difference
Why both forms exist and how they work together
Form W-2 (Per Employee)
- One W-2 for each individual employee
- Reports that employee's wages, tips, and withholding
- Sent to the employee, SSA, and state
- Copy A (red ink) goes to SSA with the W-3
- Employees use it to file their personal 1040
- Deadline: January 31 to employees and SSA
Form W-3 (Summary — One Per EIN)
- One W-3 per Employer Identification Number
- Totals wages and taxes across all employees combined
- Sent only to the Social Security Administration
- Required only with paper W-2 Copy A submissions
- Allows SSA to verify your payroll matches employee returns
- Deadline: January 31 — same as W-2
Goes to the SSA, not the IRS: Form W-3 (and the W-2 Copy A forms it transmits) goes to the Social Security Administration, not to the IRS. The IRS gets your payroll taxes through Form 941 (quarterly) or Form 944 (annual). These are separate filings — don't confuse the SSA mailing address with your IRS tax payment address.
How to Fill Out Form W-3
Box-by-box instructions — all amounts must match the sum of your W-2 forms
Box a — Control Number
Optional. Leave blank unless your payroll system uses control numbers to track submissions. Most small employers skip this box entirely.
Box b — Kind of Payer
Check exactly one box describing your organization type:
- 941 — Most businesses; choose this if unsure (quarterly employment tax filers)
- Military — Active duty military employers
- 943 — Agricultural employers (farm labor)
- 944 — Employers with annual tax liability under $1,000 (annual filers)
- CT-1 — Railroad employers
- Hshld. emp. — Household employers (nannies, domestic workers)
- Medicare govt. emp. — Government employees covered only by Medicare (not Social Security)
Box c — Total Number of Forms W-2
Enter the exact count of W-2 Copy A forms enclosed in this package. If submitting W-2s for 12 employees, enter "12". This number must match what you physically enclose — the SSA counts the forms received.
Box e — Employer Identification Number (EIN)
Enter your 9-digit EIN in XX-XXXXXXX format. This must exactly match the EIN on all attached W-2 forms. If any W-2 has a different EIN, it belongs in a separate W-3 submission. Never use a Social Security Number here.
Boxes f & g — Employer Name and Address
Enter your legal business name exactly as registered with the IRS (Box f) and your complete mailing address (Box g). The SSA uses this address for any correspondence about your filing.
Boxes 1–6 — Wage and Tax Totals
These are the core totals — the sum of the corresponding boxes across every W-2 form you're submitting:
- Box 1: Total wages, tips, and other compensation (sum of all W-2 Box 1)
- Box 2: Total federal income tax withheld (sum of all W-2 Box 2)
- Box 3: Total Social Security wages (sum of all W-2 Box 3)
- Box 4: Total Social Security tax withheld — should equal 6.2% × Box 3
- Box 5: Total Medicare wages and tips (sum of all W-2 Box 5)
- Box 6: Total Medicare tax withheld — should equal 1.45% × Box 5 (plus 0.9% Additional Medicare on wages over $200k)
Signature Section
An authorized officer or owner must sign and date in ink. Include your title (CEO, Owner, Payroll Manager), a contact person's name, phone number, and optional email address. The SSA may contact the listed person if they have questions about the submission.
Filing Deadline and Penalties
January 31 is the unified deadline for W-2s and W-3 — no extensions available
Filing Deadlines
- Give W-2 to employees: January 31
- File W-2 Copy A + W-3 with SSA: January 31
- State W-2 filing: Varies by state (check your state)
- Extensions: Rarely granted — requires extraordinary circumstances
- Tip: Prepare W-2s and W-3 in early January; don't wait until the 31st
Late Filing Penalties (Per W-2 Form)
- Within 30 days: $60 per form
- 31 days to August 1: $130 per form
- After August 1: $340 per form
- Intentional disregard: $680 per form (no maximum cap)
- Note: Penalties apply to each W-2 in the batch, not just the W-3
Reconcile before you file: Before submitting, cross-check your W-3 Box 1 total against the sum of wages reported on your quarterly Form 941s (or annual 944). If the numbers don't match, find the discrepancy before filing — it's much easier to fix now than to respond to an SSA or IRS inquiry after submission.
Common W-3 Mistakes to Avoid
Errors that cause SSA processing delays and potential penalties
W-3 Totals Don't Match the Sum of W-2s
The SSA adds up all attached W-2s and compares them to your W-3 totals. Any discrepancy triggers a letter requesting correction. Manually total every W-2 Box 1 through Box 6 and verify they match before mailing.
Stapling Forms Together
Never staple your W-2 Copy A forms to the W-3. Staples jam SSA scanning equipment and can cause your submission to be rejected or delayed. Use paper clips or rubber bands only.
Sending the Wrong W-2 Copy
The SSA only accepts W-2 Copy A — the red-ink government copy printed on special scannable paper. The employee copy (Copy B) and employer copy (Copy C) are printed on plain white paper and are not accepted. If you send copies printed on plain paper, they may be rejected.
Filing W-3 When You E-Filed
If you filed W-2s electronically through SSA Business Services Online or payroll software, do not also send a paper W-3. The electronic system generates its own transmittal record. Sending a paper W-3 after e-filing creates duplicate records and confusion.
Wrong or Missing EIN
The EIN on the W-3 must exactly match the EIN on all attached W-2 forms, and must match your IRS records. A transposed digit or old EIN from before a business restructuring causes the SSA to be unable to post wages to employee accounts.
Box c Count Doesn't Match Actual W-2s Enclosed
If Box c says "15" but you only enclosed 13 W-2 Copy A forms, the SSA will flag the discrepancy. Count your forms carefully before sealing the envelope. If sending corrections later, use Form W-2c and Form W-3c — not a revised W-3.
Frequently Asked Questions
Common questions about Form W-3 and payroll transmittal requirements
Do I need to file W-3 if I file W-2s electronically?
No. Form W-3 is only required when submitting paper W-2 Copy A forms to the SSA. If you use SSA Business Services Online, QuickBooks, Gusto, ADP, or any payroll software that files electronically, the system handles the transmittal automatically. Do not also send a paper W-3 — it creates duplicate records.
Where do I send Form W-3 and the W-2 Copy A forms?
Mail to the Social Security Administration Data Operations Center in Wilkes-Barre, PA — not to the IRS. The exact address is: Social Security Administration, Data Operations Center, Wilkes-Barre, PA 18769-0001. Use certified mail with return receipt so you have proof of timely filing.
What if I discover an error after filing my W-3?
File a Form W-3c (Transmittal of Corrected Wage and Tax Statements) along with Form W-2c for each affected employee. The W-3c shows the original amounts and the corrected amounts side by side. File corrections as soon as you discover errors to minimize potential SSA issues for your employees' Social Security records.
Do I file one W-3 per employee or one for all employees?
One W-3 covers all employees under a single EIN. If your business has only one EIN, submit one W-3 with all W-2 Copy A forms. If you operate multiple entities with different EINs, each EIN requires its own W-3 — even if the same person owns all the companies.
Does Form W-3 go to the IRS or the SSA?
Form W-3 goes to the Social Security Administration (SSA), not the IRS. The SSA uses W-3 and W-2 data to post earnings to employees' Social Security records, which determines future Social Security benefit amounts. Your IRS payroll tax obligations are reported separately via Form 941 (quarterly) or 944 (annual).
How long should I keep copies of W-3 and W-2?
Keep copies for at least 4 years after the filing due date or the date you paid the taxes, whichever is later. This covers the standard IRS and SSA audit window. Many payroll professionals recommend keeping W-2 and W-3 records indefinitely, since disputes about employees' Social Security earnings can arise years or decades later.
What's the difference between Form W-3 and Form 1096?
Both are transmittal forms, but they go to different agencies for different form types. Form W-3 transmits W-2 wage statements to the Social Security Administration. Form 1096 transmits 1099 information returns (1099-NEC, 1099-MISC, etc.) to the IRS. They have the same purpose — cover sheet and totals — but serve completely different filing systems.

About Form W-3
Form W-3 (Transmittal of Wage and Tax Statements) is the SSA cover sheet that accompanies paper W-2 Copy A forms. Employers submit one W-3 per EIN, summarizing total wages, Social Security wages, Medicare wages, and all associated tax withholdings across every employee's W-2 for the calendar year. The SSA uses this data to post earnings to employee Social Security accounts, directly affecting future benefit calculations.
Form W-3 is only required for paper filing. Electronic filers — increasingly the standard since the IRS lowered the mandatory e-file threshold to 10 forms in 2024 — never file a separate W-3. For employers still filing on paper, the W-3 and W-2 Copy A forms must arrive at the SSA Data Operations Center by January 31. Never staple; use paper clips. Send only the official red-ink W-2 Copy A, never plain-paper copies.
Think of the W-3/W-2 relationship the same way as the Form 1096/Form 1099 relationship — a transmittal paired with individual information returns. The key difference: W-3 goes to the SSA while 1096 goes to the IRS. For a complete employer payroll guide, see our complete W-3 transmittal guide for 2026.
