Error
The SSN on the Form W-2 for the Primary taxpayer or the Spouse must match the SSN entered on your Form 1040.
Solution
There is a problem with the Employee’s SSN on the Form W-2. The SSN on any Form W2 submitted with a Free File Fillable Forms return must be the same as the primary or secondary SSN on the tax return. (This rule does not apply if the primary or secondary taxpayer is using an ITIN on the 1040 form.)
Review the SSN on your 1040 and all W2’s to make sure they are correct.
Make the correction(s) and resubmit.
If you are making a payment, you may have to re-date Step 3, Payment Options.
