Verify employee data:
Verify employee full name
Verify employee address
Verify employee Social Security number
File W-2

It’s important to review employee data at the end of the year, particularly with employee names, addresses, and Social Security numbers. Improperly filing this could lead to penalties for each misfiled W-2. Check with your employees to make sure their employee information is correct. The deadline to furnish the W-2 is January 31st.

If you’re still not certain about your employee’s Social Security number or just want to get it verified, the IRS provides employers with the Social Security Number Verification Service (SSNVS) to minimize employee name and SSN mismatches.

Don’t forget to verify employee data for both active and terminated employees.
