High-income W-2 employees who need to understand both standard and additional Medicare tax rates
How much Medicare tax do high earners pay?
High earners pay two separate Medicare taxes:
1. Standard Medicare tax: 1.45% on all wages (no cap)
2. Additional Medicare Tax: 0.9% on wages over $200,000 (single) or $250,000 (married filing jointly)
This creates a total Medicare tax rate of 2.35% on income above the threshold.
Example: $300,000 salary Medicare tax calculation
Let's break down the Medicare tax for someone earning $300,000 annually:
Standard Medicare Tax (1.45% on all wages):
Additional Medicare Tax (0.9% on wages over $200,000):
Total Medicare Tax:** $4,350 + $900 = **$5,250
When the Additional Medicare Tax kicks in
Your employer starts withholding the extra 0.9% once your year-to-date wages exceed the threshold. For a $300,000 salary paid biweekly:
Key differences from Social Security tax
No cap: Unlike Social Security tax (capped at $176,100), Medicare tax applies to ALL wages. A $1 million earner pays Medicare tax on every dollar.
No employer match on additional tax: Your employer pays 1.45% Medicare tax too, but NOT the additional 0.9%. You pay the extra 0.9% alone.
Different thresholds for married couples: The $200,000 threshold doesn't double for married couples - it jumps to $250,000.
Filing status thresholds for Additional Medicare Tax
What you should do
If you're approaching the Additional Medicare Tax threshold, consider timing bonuses or stock option exercises to manage the tax impact. The additional 0.9% can add up quickly on large compensation events.

Key takeaway: High earners pay 2.35% total Medicare tax (1.45% + 0.9%) on income above $200,000 single/$250,000 married, with no income cap unlike Social Security.

W-2 employees earning under $200,000 who want to understand when Medicare tax increases
Medicare tax for typical earners
If you earn under $200,000 (single) or under $250,000 (married filing jointly), you only pay the standard 1.45% Medicare tax on all your wages. There's no Medicare tax cap - you pay 1.45% on every dollar you earn.
Comparing Medicare to Social Security tax
Medicare: 1.45% on ALL wages (no cap)
Social Security: 6.2% on wages up to $176,100 (then $0)
Example for $100,000 earner:
When to worry about Additional Medicare Tax
Start planning when your income approaches the thresholds:
Remember: bonuses, overtime, and stock compensation count toward these thresholds.
Key takeaway: Most W-2 employees pay just 1.45% Medicare tax with no cap, but should plan ahead as income approaches $200,000 single/$250,000 married.

Pre-retirees who want to understand Medicare tax on retirement distributions and part-time work
Medicare tax in retirement transition
Medicare tax only applies to earned income (wages, self-employment). Most retirement income is NOT subject to Medicare tax:
Exempt from Medicare tax:
Subject to Medicare tax:
Bridge employment considerations
Many pre-retirees work part-time or consult before full retirement. If your "bridge job" pays $80,000, you'll pay $1,160 in Medicare tax (1.45%) - much less than your high-earning years.
Self-employment caveat: Consulting income faces the full 2.9% self-employment Medicare tax (both employee and employer portions), plus the 0.9% additional tax if you exceed the thresholds.
Planning tip for high-earner retirees
If you had high earnings and plan to work part-time in retirement, your reduced wages likely won't trigger the Additional Medicare Tax. This creates tax savings compared to your peak earning years.
Key takeaway: Retirement income like 401(k) distributions and Social Security is exempt from Medicare tax, but bridge employment wages still face the 1.45% rate.
