Employers can file W-2C prior year corrections to fix mistakes on previously filed W-2 forms. If wages, withholdings, or employee details were wrong in a prior year, you must file a W-2C correction and give the employee a copy. You can prepare and e-file corrections quickly with our W-2C software.
When to File W-2C Prior Year Corrections
You should submit a W-2C prior year correction when:
-
Wages or tips were reported incorrectly.
-
Tax withholdings (federal income tax, Social Security, Medicare) were wrong.
-
Employee details such as name, SSN, or address were inaccurate.
-
Benefits or deductions were miscalculated or omitted.
By correcting these errors, you protect both your business and your employees from IRS issues.
How a W-2C Correction for Prior Years Works
A W-2C form clearly shows what changed:
-
Box A lists the incorrect data.
-
Box B provides the corrected data.
The employee receives a copy so they can amend their tax return if necessary. This ensures both the IRS and the employee have accurate records.
Why Filing Matters
Submitting accurate W-2C prior year corrections prevents penalties and avoids IRS notices. It also ensures employees report the correct income on their returns. According to the IRS Instructions for Forms W-2 and W-3, proper corrections are required to stay compliant.
