Medicare tax on a paycheck

Short answer

Medicare tax is 1.45% of all wages, with no yearly cap, and the employer pays a matching 1.45%. Once an employee's wages for the year pass $200,000, the employer must also withhold 0.9% Additional Medicare Tax on the excess, starting in that pay period; there's no employer share of the additional 0.9%.

See Medicare with social security and federal income tax for any paycheck.

Worked examples

  • $2,000 paycheck: 1.45% = $29.00 withheld, and the employer pays another $29.00.
  • $1,000 paycheck with $250,000 already paid this year: $14.50 plus 0.9% of $1,000, $9.00, so $23.50.
  • $3,000 paycheck that takes the year from $199,000 to $202,000: $43.50 plus 0.9% of the $2,000 over $200,000, $18.00, so $61.50.

The employer withholds the 0.9% based on wages it pays, whatever the employee's filing status. The employee settles any difference on their tax return.

Questions

Is there a limit on Medicare tax?

No. Unlike social security, Medicare applies to all wages, and above $200,000 in a year the rate withheld rises by 0.9%.

Does a 401(k) lower Medicare tax?

No. Elective 401(k) deferrals are still subject to social security and Medicare, though they generally lower federal income tax withholding.
