What is a W-3 Form? W-3 Form filing instructions
When you run payroll, one thing is guaranteed you cannot file W-2s without also filing Form W-3. It tells the Social Security Administration (SSA) the total wages, taxes withheld, Social Security wages, and Medicare wages for your entire workforce.
What Is a W-3 Form?
Form W-3 "Transmittal of Wage and Tax Statements" is a one-page form that summarizes all theW-2 information for your business.If W-2s show income for each employee, the W-3 form shows:
- Total wages paid to ALL employees
- Total federal income taxwithheld
- Total Social Security and Medicare wages
- Total Social Security and Medicare tax withheld
- Number of W-2s submitted
You cannot submit W-2s to the SSA without a W-3. They go together like a cover letter + attachments.

W-3 vs W-2: What's the Difference?
| W-2 Form | W-3 Form |
|---|---|
| One per employee | One per employer |
| Shows individual wages | Summarizes all wages |
| Given to employees | Sent only to SSA |
| Required for tax filing | Required for W-2 processing |
| Lists employee taxes | Lists total business taxes |
How a W-3 Works
If you run a small business with 5 employees.
You issued these W-2 totals:
- Total wages: $210,000
- Federal income tax withheld: $28,300
- Social Security wages: $210,000
- Social Security tax withheld: $13,020
- Medicare wages: $210,000
- Medicare tax withheld: $3,045
Your W-3 simply adds up all five W-2s and reports the totals above.
