📄 What Is Form W-2?
Form W-2, Wage and Tax Statement, is used to report the wages paid to each employee and the taxes withheld during the calendar year. You must provide a copy of the W-2 to your employee and file it with the SSA.
Key details reported on a W-2 include:
- Employee wages, tips, and other compensation
- Federal income tax withheld
- Social Security and Medicare taxes withheld
- State income tax withheld (if applicable)
- Retirement contributions and benefits
📦 What Is Form W-3?
Form W-3, Transmittal of Wage and Tax Statements, is the summary form that accompanies all W-2s you file with the SSA. It provides a total of all wages paid and taxes withheld, as reported across all W-2s.
Even if you only have one employee, you must file both W-2 and W-3 forms. The W-3 form is submitted only to the SSA—not to your employees.
🗓️ Filing Deadlines for 2025
- Employee Copy of W-2: Must be provided to employees by January 31, 2026.
- SSA Filing (W-2 and W-3): Also due by January 31, 2026.
Late filings can result in penalties ranging from $60 to $310 per form, depending on how late the submission is. Avoid penalties by filing early and electronically.
🛠️ How to File W-2 and W-3 as a Sole Proprietor
You can file Forms W-2 and W-3 using one of the following methods:
- Online Filing through SSA’s BSO (Business Services Online): Recommended for quick and free submissions.
- Payroll Software: Most payroll tools generate W-2/W-3 automatically.
- Paper Filing: You can order official IRS forms and mail them to the SSA (not recommended due to longer processing times).
