Medicare wages and tips on a W-2 represent the total amount of an employee’s earnings that are subject to Medicare tax for the year. This includes regular wages, tips, bonuses, commissions, and most other taxable compensation. Employers report this number in Box 5 of the W-2 form. It is often higher than the amount shown in Box 1 because Medicare wages do not exclude pretax deductions such as 401k contributions. These wages help determine how much Medicare tax is withheld and can affect how employees calculate tax liabilities.
