What Medicare Wages and Tips Mean on Your W2

Medicare wages and tips is the total amount of your earnings that is subject to Medicare tax. It appears in Box 5 of your W2 form and includes your regular wages, bonuses, commissions, and tips — basically everything your employer paid you during the year, with only a few narrow exceptions. This figure is what determines how much Medicare tax you and your employer each paid on your behalf.

Medicare tax funds the hospital insurance part of Medicare (Part A), which covers inpatient hospital stays, skilled nursing facility care, hospice, and home health services. Unlike Social Security tax, which stops once you reach a certain income threshold, Medicare tax applies to all your wages with no upper limit — you pay it on every dollar you earn.

The Medicare tax rate is 2.9 percent of your Medicare wages: you pay 1.45 percent and your employer pays 1.45 percent. If you are self-employed, you pay both portions. Additionally, if your income exceeds certain thresholds (currently $200,000 for single filers, $250,000 for married filing jointly), you pay an extra 0.9 percent Medicare tax on the amount above that threshold.

Key Takeaways

  • Medicare wages and tips in Box 5 of your W2 include all wages, bonuses, commissions, and tips you received during the year.
  • This amount determines how much Medicare tax you paid, which funds hospital insurance (Part A) coverage.
  • Medicare tax is 2.9 percent total (1.45 percent from you, 1.45 percent from your employer), with no income cap.
  • If your income exceeds $200,000 (single) or $250,000 (married filing jointly), you pay an additional 0.9 percent Medicare tax on earnings above that threshold.
  • Medicare wages and tips usually match your gross wages, but certain employer-provided benefits and pre-tax deductions may be excluded.

What Is Included in Medicare Wages and Tips

Medicare wages include your regular hourly pay or salary, overtime, bonuses, commissions, and any tips you reported to your employer. They also include certain employer-provided benefits that count as taxable income, such as the value of a company car used for personal reasons or the cost of group term life insurance above $50,000.

Tips are a significant part of this calculation if you work in service industries. You are required to report tips to your employer, and those tips count as Medicare wages. If you received tips in cash and did not report them, your employer may estimate them based on credit card receipts or other records, and those estimated tips still count toward your Medicare wages.

Certain deductions reduce your Medicare wages. Contributions to a traditional 401(k), health insurance premiums paid through payroll, and dependent care flexible spending account contributions are all taken out before Medicare tax is calculated, so they lower your Medicare wages on the W2.

What Is Not Included in Medicare Wages

Some forms of compensation do not count as Medicare wages. Employer contributions to your health insurance plan are not included — only your own contributions reduce your Medicare wages. Reimbursements for business expenses, such as mileage or meal allowances, are not Medicare wages if they meet IRS rules for accountable plans.

Certain fringe benefits are also excluded: employer-paid parking (up to $300 per month), transit passes (up to $300 per month), and may have access to adoption information are not Medicare wages. Scholarships and fellowships used for tuition and required course materials are excluded, as are certain educational information benefits.

Disability benefits paid by your employer while you are on leave do not count as Medicare wages in most cases. However, if you receive a lump-sum payment when you leave your job — such as unused vacation or severance — that payment usually does count as Medicare wages in the year you receive it.

How Medicare Wages Affect Your Medicare Taxes

Your Medicare wages determine the amount of Medicare tax withheld from your paycheck. If your Medicare wages for the year are $60,000, you will pay $870 in Medicare tax (1.45 percent of $60,000). Your employer also pays $870, for a total of $1,740 in Medicare tax funding your Part A coverage.

The additional 0.9 percent Medicare tax applies only to wages above the income threshold for your filing status. If you are single and earn $220,000, you pay the standard 1.45 percent on all $220,000, plus an additional 0.9 percent on the $20,000 above the $200,000 threshold. That extra amount is $180, in addition to the standard $3,190.

If you work for more than one employer in a single year, each employer withholds Medicare tax based on the wages they pay you. You do not get a refund if your total Medicare tax exceeds what you owe, but you can claim the overage as a credit on your tax return if one employer withheld too much.

Why Medicare Wages Matter for Your Future Benefits

Medicare wages are recorded in your Social Security account and contribute to your Medicare coverage record. To be covered by Medicare Part A at age 65, you generally need 40 quarters of coverage — roughly 10 years of work. Each quarter in which you earned at least a minimum amount (currently $1,640 per quarter, though this changes yearly) counts toward that requirement.

Your Medicare wages do not directly affect the amount of your Part A benefits — Part A is not means-tested and does not vary based on how much you earned. However, your earnings record does affect your Social Security retirement benefits, which are calculated using your highest 35 years of earnings. Higher Medicare wages usually mean higher earnings in your record.

If you continue working past age 65, your Medicare wages continue to be recorded. You can request a Social Security Statement online to see your earnings history and verify that your Medicare wages are being credited correctly. Errors in your record can affect both your Social Security benefits and your Medicare may be able to access, so it is worth checking periodically.

Reading Box 5 on Your W2

Your W2 form has several wage boxes, and it is straightforward to confuse them. Box 1 shows your federal income tax wages — the amount used to calculate federal income tax withholding. Box 5 shows your Medicare wages and tips, which is the amount subject to Medicare tax. These two numbers are often the same, but they can differ if you have pre-tax deductions like 401(k) contributions or health insurance premiums.

Box 6 shows your Social Security wages, which is similar to Medicare wages but has a cap — in 2024, Social Security tax applies only to the first $168,600 of wages. Medicare wages have no cap, so Box 5 will be higher than Box 6 if you earned more than that threshold.

If you received tips, Box 5 will include them. If you received non-cash tips (such as gift cards or merchandise), your employer should have included their fair market value in your Medicare wages. If you believe your Medicare wages are incorrect, contact your employer's payroll department or the IRS to request a corrected W2.

Frequently Asked Questions

Does my Medicare wage amount affect how much I pay for Medicare Part B or Part D?

Your Medicare wages themselves do not determine your Part B or Part D premiums. However, your income in the current year and the prior two years does affect your premiums through a process called Income-Related Monthly Adjustment Amounts (IRMAA). Higher income can result in higher premiums for Part B and Part D coverage.

What if my W2 shows the wrong Medicare wages?

Contact your employer when ready and ask them to issue a corrected W2 (Form W2-c). You will need the corrected form to file your taxes accurately. If your employer does not respond, you can file Form SS-8 with the IRS to report the discrepancy, though this process takes time.

Are tips I received in cash included in Medicare wages if I did not report them?

Your employer is required to report tips based on your reports and credit card records. If you did not report cash tips, they may not appear on your W2 unless your employer has other evidence of them. However, you are legally required to report all tips, whether cash or card, so unreported tips should be included in your tax return.

If I work part-time at two jobs, how do Medicare wages work?

Each employer reports the Medicare wages they paid you on a separate W2. You will receive two W2 forms, one from each employer. Your total Medicare tax is calculated on the combined wages from both jobs, and you report both W2s when you file your taxes.

Do Medicare wages include bonuses and commissions?

Yes. Bonuses, commissions, and any other compensation your employer pays you count as Medicare wages. They are subject to the same 1.45 percent Medicare tax as your regular wages.
