After you file

Does your health insurance premium take out of your paycheck pre-tax or after-tax? If your premium is paid with pre-tax money, that money will not be included as income in Box1 (wages) on your W-2. If your premiums are paid with after-tax money, that money will be included as an income on your W-2. 

If you think it is a mistake in your W-2, talk to your employer first.

If by the end of February, your attempts to have the Form W-2, Wage, and Tax Statement, corrected by your employer, are unsuccessful, you can request that an IRS representative initiate a Form W-2 complaint. Call the IRS toll free at 800-829-1040 or visit an IRS Taxpayer Assistance Center (TAC). https://www.irs.gov/faqs/irs-procedures/w-2-additional-incorrect-lost-non-receipt-omitted/w-2-additi...
