What is Form W-3 and How is it reported in 2026?

What Is IRS Form W-3?

IRS Form W-3, Transmittal of Wage and Tax Statements, is a summary form that accompanies paper Forms W-2 when they are filed with the Social Security Administration (SSA). It totals the wages and taxes reported on all W-2s you are submitting for a given tax year.

Think of Form W-3 as the cover sheet for your W-2 filing package. While each W-2 reports information for a single employee, the W-3 shows the combined figures for all W-2s, helping the SSA and IRS reconcile your payroll reporting.

Who Must File Form W-3?

Employers that file paper Forms W-2 with the SSA are generally required to include a single Form W-3 for that submission. This includes:

Businesses with employees who received wages reported on Form W-2
Household employers filing paper W-2s for household workers
Tax professionals filing paper W-2s on behalf of client employers

If you file W-2s electronically through the SSA's online systems, you generally do not mail a paper Form W-3. The SSA's e-file system creates the W-3 information from your electronic W-2 data.

When Is Form W-3 Due?

The due date for filing Form W-3 with the SSA is the same as the deadline for filing Copy A of Form W-2. In most years, W-2 and W-3 forms must be submitted to the SSA by January 31 following the end of the tax year.

Employers must also furnish W-2 copies to employees by January 31. Always confirm current-year deadlines in the latest IRS and SSA guidance, as dates can shift when they fall on weekends or holidays.

How to Complete Form W-3: Key Sections

Form W-3 is relatively short, but it must accurately summarize every W-2 in your submission. At a high level, you will need to:

Enter your employer information, including legal name, address, Employer Identification Number (EIN), and contact details.
Check the appropriate Kind of Payer and Kind of Employer boxes (such as 941, 943, 944, or government employer).
Report the total number of W-2 forms being transmitted with this W-3.
Complete the wage and tax totals by adding up amounts from all W-2s for boxes such as: total wages, Social Security wages, Medicare wages, federal income tax withheld, and any other applicable boxes.
Sign and date the form (or have an authorized signer do so) to certify that the information is correct.

The totals on Form W-3 should match the sum of the corresponding boxes across all Forms W-2 you are submitting. Discrepancies can trigger notices or processing delays, so many employers rely on payroll or e-file software to help validate these amounts.

Common Form W-3 Mistakes to Avoid

Using an incorrect or outdated employer name or EIN
Checking the wrong Kind of Payer or Kind of Employer box
Reporting wage and tax totals that do not match the attached W-2 forms
Forgetting to include one or more W-2s in your totals
Missing the filing deadline or mailing forms to the wrong SSA address

Reviewing your W-3 carefully before filing or using an IRS-approved W-2/W-3 e-file provider can help you avoid costly penalties and amended filings.

Frequently Asked Questions About Form W-3

Do I file a separate Form W-3 for each W-2?

No. You generally file one Form W-3 for each batch of paper Forms W-2 you submit to the SSA. That W-3 summarizes the total number of W-2s and the combined wage and tax amounts for that submission.

Is Form W-3 required if I e-file my W-2s?

When you file W-2s electronically through the SSA, you do not usually mail a separate paper Form W-3. The SSA's e-file system captures the W-3 summary information from your electronic W-2 data.

What if my W-3 totals do not match my W-2 forms?

Your W-3 totals should always match the sum of the corresponding boxes on all attached W-2s. If they do not, review your payroll records, correct any errors on W-2s, and prepare a corrected W-3 before filing.

Where do I send paper Forms W-2 and W-3?

Paper W-2 and W-3 forms are filed with the Social Security Administration, not directly with the IRS. Use the latest SSA filing instructions or IRS Publication 15 for the correct mailing address and any special rules.

Does an Independent Contractor get a W-2?

The short answer is no. An independent contractor shouldn’t expect to receive a Form W-2. Instead, they should receive a 1099. A 1099 has a completely separate set of rules that do not apply to the answers found here.

What is Form W-3?

IRS Form W-3, Transmittal of Wage and Tax Statements, is only required when the employer is opting to paper file. A Form W-3 is a transmittal or cover sheet that comes before the stack of W-2 forms. It provides the SSA with a summary of the information being filed. Employers should never file a Form W-3 by itself; it should always be accompanied by the corresponding Form W-2.

The form includes information about the filer, the total number of forms, and totals of all of the wages, withholding, and other amounts being filed.
