Medicare wages and tips are the earnings Medicare uses to calculate your payroll tax, and they appear on your W-2 form in Box 5
Medicare wages and tips are not a separate payment or a new category of income. They are the total amount of your wages, salary, bonuses, and tips that your employer uses to figure out how much Medicare tax you owe. Medicare tax funds the Hospital Insurance part of Medicare — the part that covers hospital stays, skilled nursing, hospice, and home health. Unlike Social Security tax, which stops once you hit an annual earnings cap, Medicare tax applies to all your wages with no upper limit.
Your employer withholds Medicare tax at a rate of 1.45 percent from your paycheck. If you are self-employed, you pay both the employee and employer portions — 2.9 percent total. If your income exceeds certain thresholds (currently $200,000 for single filers, $250,000 for married filing jointly), you also pay an additional 0.9 percent Medicare tax on the excess. Your W-2 form shows your Medicare wages and tips in Box 5 so you can verify the amount your employer reported to the IRS.
Key Takeaways
- Medicare wages and tips are the earnings your employer uses to calculate your Medicare tax withholding, shown in Box 5 of your W-2.
- Medicare tax is 1.45 percent for employees and 2.9 percent for self-employed people, with no annual earnings cap like Social Security has.
- Tips count as Medicare wages, including both cash tips you report to your employer and charged tips on credit cards.
- If you earned over $200,000 (single) or $250,000 (married filing jointly), you owe an additional 0.9 percent Medicare tax on the excess income.
What counts as Medicare wages and tips
Medicare wages include your regular salary or hourly wages, overtime pay, bonuses, commissions, and certain fringe benefits your employer provides. If your employer gives you a taxable benefit — such as a company car you use for personal reasons, or a health insurance premium they pay on your behalf above a certain threshold — that amount counts as a Medicare wage too. The rule is broad: almost any payment your employer makes to you for work is a Medicare wage.
Tips are included in full. This covers cash tips you hand-report to your employer, tips added to credit card charges, and tips from customers that your employer records. If you work in food service, housekeeping, transportation, or any job where tips are common, all of those amounts go into your Medicare wages total. You must report tips to your employer so they can withhold the correct Medicare tax.
A few items do not count as Medicare wages. Employer contributions to a traditional 401(k) or 403(b) plan are excluded — that is why those contributions reduce your taxable income. Health insurance premiums you pay through a cafeteria plan (Section 125) are also excluded. Certain other pre-tax deductions, like transit benefits or dependent care accounts, do not count either. Your pay stub should show these deductions separately so you can see what was subtracted before Medicare tax was calculated.
Why Medicare wages matter for your tax return
The amount in Box 5 of your W-2 determines how much Medicare tax you paid during the year. When you file your tax return, you use this figure to make sure your withholding was correct. If you had multiple jobs or were self-employed, you may owe additional Medicare tax at tax time because each employer withholds based only on what they paid you — not on your total income across all jobs.
For example, if you earned $150,000 at one job and $100,000 at a second job, each employer withheld Medicare tax on their portion only. But because your combined income exceeds $200,000, you owe the extra 0.9 percent Medicare tax on the $50,000 over the threshold. You calculate and pay this when you file your return. Your tax software or a tax preparer can walk you through this calculation.
How self-employed people report Medicare wages
If you are self-employed, you do not receive a W-2. Instead, you report your net business income on Schedule C (for sole proprietors) or your share of partnership income on Schedule K-1. You then use Schedule SE to calculate your self-employment tax, which includes both the employee and employer portions of Medicare tax.
Self-employed Medicare tax is 2.9 percent of your net earnings from self-employment (after you deduct half of your self-employment tax itself). You pay this in full — there is no employer to split the cost with. If your net self-employment income exceeds $200,000 (single) or $250,000 (married filing jointly), you also owe the additional 0.9 percent Medicare tax on the excess. You can deduct half of your self-employment tax as an adjustment to income, which lowers your taxable income slightly.
The difference between Medicare wages and Social Security wages
Social Security wages and Medicare wages are calculated almost the same way, but they have one critical difference: the earnings cap. Social Security tax applies only to wages up to an annual limit — in 2024, that limit is $168,600. Once you earn that much, your employer stops withholding Social Security tax for the rest of the year. Medicare tax has no cap. You pay Medicare tax on every dollar you earn, no matter how high your income goes.
Both appear on your W-2. Box 3 shows your Social Security wages (capped at the annual limit), and Box 5 shows your Medicare wages and tips (uncapped). If you earned more than the Social Security cap, you will notice that Box 3 stops at the cap amount while Box 5 continues to your actual total earnings. This is normal and expected.
Common mistakes when reporting Medicare wages
One frequent error is forgetting to report all tips to your employer. If you receive cash tips and do not report them, your employer cannot withhold the correct Medicare tax. This can leave you owing money at tax time. The IRS expects you to report all tips, including cash, so keep a daily log if you receive cash payments.
Another mistake is not accounting for multiple jobs when calculating the additional 0.9 percent Medicare tax. Each employer withholds based only on what they paid you individually. If your combined income from all jobs exceeds the threshold, you must calculate and pay the extra tax yourself when you file. Many people discover this at tax time and are surprised by the bill.
A third error is misunderstanding what counts as a Medicare wage. Some people think that pre-tax deductions like 401(k) contributions reduce Medicare wages, but they do not — Medicare tax is calculated on your gross pay before those deductions. Only specific items like health insurance premiums paid through a cafeteria plan reduce Medicare wages. Check your pay stub to see exactly what your employer counted.
Where to find your Medicare wages on tax documents
If you are an employee, look at Box 5 of your W-2 form. This box is labeled "Medicare wages and tips" and shows the total amount your employer reported to the IRS. Compare this to your pay stubs throughout the year to make sure it matches your records. If it does not, contact your employer's payroll department to request a corrected W-2 (Form W-2c).
If you are self-employed, your Medicare wages are your net self-employment income, which you calculate on Schedule C or Schedule K-1 depending on your business structure. You then transfer this figure to Schedule SE to compute your self-employment tax. If you use tax software, it will guide you through these forms and calculate the correct amount automatically.
Frequently Asked Questions
Do tips I report to my employer count as Medicare wages?
Yes. All tips you report to your employer — whether cash or charged to a card — count as Medicare wages. Your employer withholds Medicare tax on the total, including tips. If you receive cash tips and do not report them, you are not paying the correct Medicare tax and may owe money at tax time.
What if my W-2 shows the wrong amount in Box 5?
Contact your employer's payroll or human resources department and ask them to review the figure. If an error is confirmed, they will issue a corrected W-2 (Form W-2c) and send it to you and the IRS. You may then file an amended tax return if needed. Keep copies of all pay stubs to support your claim.
Do I pay Medicare tax on my 401(k) contributions?
No. Contributions to a traditional 401(k) or 403(b) are deducted from your gross pay before Medicare tax is calculated, so they do not count as Medicare wages. However, employer matching contributions and any employer profit-sharing do count as Medicare wages.
Why do I owe extra Medicare tax if I have two jobs?
Each employer withholds Medicare tax only on what they pay you. If your combined income from all jobs exceeds $200,000 (single) or $250,000 (married filing jointly), you owe an additional 0.9 percent Medicare tax on the excess. You calculate and pay this when you file your return because no single employer knew your total income.
Is Medicare tax the same as Medicare premiums?
No. Medicare tax is the payroll tax you pay while working, which funds the Hospital Insurance part of Medicare. Medicare premiums are what you pay monthly once you are enrolled in Medicare, usually deducted from your Social Security check. They are separate costs.
