Medicare Wages and Tips Meaning: Box 5 Guide (2026)

You're looking at Box 5 of your W-2, and the number is bigger than your salary. That's not a mistake. The Medicare wages and tips meaning trips up plenty of people at tax time. Here's what it reports, how to calculate it, and why it rarely matches Box 1. Need pay records of your own? Our pay stub generator can help.

Key Takeaways

• Box 5 reports every dollar of pay subject to Medicare tax, with no annual cap
• The 2026 Medicare rate is 1.45% from the employee and 1.45% from the employer
• 401(k) contributions do not reduce Medicare wages, which is why Box 5 often exceeds Box 1
• Reported tips of $20 or more per month per employer belong in Box 5
• An extra 0.9% applies to wages above $200,000

Medicare Wages and Tips Meaning on Your W-2

Box 5 of your W-2 shows every dollar you earned that Medicare tax applied to, including wages, bonuses, commissions, and reported tips. Unlike Social Security wages in Box 3, Box 5 has no annual cap, so all covered earnings land there regardless of income.

Box 6 beside it holds the tax withheld, not the wages.

What Counts as Medicare Wages

Almost everything you're paid belongs in Box 5:

• Salary, hourly pay, and overtime
• Bonuses, commissions, and cash awards
• Reported tips
• Taxable fringe benefits, like a company car
• PTO payouts, sick pay, and severance pay

Severance pay still carries Medicare tax even after the employee leaves.

What Is Not Subject to Medicare Tax

Only a short list of pre-tax deductions reduces Medicare wages. That list covers health premiums, health FSA, and HSA contributions taken through a Section 125 cafeteria plan. Accountable-plan expense reimbursements also count. Retirement deferrals do not. Your 401(k) and 403(b) contributions stay subject to Medicare tax even though they are excluded from federal income tax.

The IRS counts elective deferrals as wages for Social Security and Medicare, so they appear in Box 3 and Box 5.

The Medicare Tax Rate in 2026

For 2026, the Medicare tax rate is 1.45% from you and 1.45% from your employer, or 2.9% combined. There's no wage base limit, so it hits every dollar in Box 5.

Once wages pass $200,000, an extra 0.9% Additional Medicare Tax applies. Your employer withholds it at that flat mark regardless of filing status. Your real liability starts at $250,000 for joint filers, or $125,000 if you file separately. You settle up on Form 8959, and employers never match the 0.9%. Medicare tax is half of FICA tax, alongside Social Security payroll taxes.

How to Calculate Medicare Wages

To calculate Medicare wages, start with total gross income, then subtract only Section 125 pre-tax deductions such as health premiums, FSA, and HSA (health savings account) contributions. Do not subtract 401(k) contributions. On $90,000 gross pay with $3,000 in pre-tax health premiums and $5,000 in 401(k) deferrals, Medicare wages equal $87,000.

Laid out line by line:

Multiply $87,000 by 1.45% and you get $1,261.50 in Box 6. The employer match adds another $1,261.50.

Why Your Medicare Wages and Tips Exceed Box 1

Box 5 usually exceeds Box 1 because pre-tax retirement contributions lower your taxable income but not your Medicare wages. A $5,000 401(k) deferral cuts Box 1 by $5,000 and leaves Box 5 untouched. Box 3 can be smaller too, since the Social Security wage base stops at $184,500 for 2026.

A mismatch across these three W-2 boxes is normal.

How Tips Affect Medicare Wages

Tips are Medicare wages too. Report cash tips to your employer once they reach $20 in a month at that job, and Medicare tax gets withheld alongside your regular pay.

A server earning $45,000 plus $5,000 in reported tips shows $50,000 in Box 5, with $725 withheld.

How Employers Report Medicare Wages and Tips

Employers report the wages in Box 5 and the tax withheld in Box 6. The same numbers roll up quarterly on Form 941, or annually on Form 944 for small employers.

Worth doing: compare the year-to-date Medicare wages on your final pay stub against Box 5. If they don't match, ask payroll for a corrected W-2 before filing.
