FICA Med Tax Is the Medicare Portion of Your Payroll Deduction

FICA Med Tax is the Medicare tax withheld from your paycheck. It funds the federal Medicare program, which pays for hospital insurance, doctor visits, and other medical services for people age 65 and older, some younger people with disabilities, and people with end-stage renal disease. Your employer withholds this tax automatically — you do not choose whether to pay it.

The Medicare tax rate is 1.45% of your gross wages. Your employer also pays 1.45%, for a total of 2.9% going into the Medicare system. If you are self-employed, you pay both portions yourself, which comes to 2.9% of your net earnings. There is no income cap on Medicare tax — unlike Social Security tax, which stops after you earn a certain amount each year, Medicare tax applies to every dollar you make.

On your pay stub, you will see "Med Tax," "Medicare Tax," or sometimes just "Med" listed as a deduction. The amount withheld depends on your gross pay and the pay period. If you earn $2,000 in a two-week period, for example, $29 goes to Medicare tax.

Key Takeaways

  • FICA Med Tax is 1.45% of your wages, withheld by your employer to fund Medicare hospital and medical insurance.
  • Your employer also pays 1.45%, but that amount does not appear on your pay stub because it comes from the employer's side.
  • Unlike Social Security tax, there is no earnings cap — Medicare tax applies to all your income no matter how much you make.
  • Self-employed people pay both the employee and employer portions, totaling 2.9% of net self-employment income.
  • High earners may pay an additional 0.9% Medicare tax on wages above a threshold set by income level and filing status.

How Much You Pay and When

The standard Medicare tax rate is 1.45% of your gross wages. This is calculated on every paycheck, regardless of how much you have already earned that year. If you are paid weekly, biweekly, or monthly, the tax is computed the same way: 1.45% of that period's gross pay.

There is also an Additional Medicare Tax of 0.9% that applies if your wages exceed certain thresholds. For 2024, the thresholds are $200,000 for single filers, $250,000 for married filing jointly, and $125,000 for married filing separately. Once your wages cross that threshold in a calendar year, an extra 0.9% is withheld on all income above it. Your employer is responsible for tracking this and withholding it correctly.

If you have multiple jobs, each employer withholds based only on the wages they pay you. You may end up overpaying Additional Medicare Tax if your combined wages from all jobs exceed the threshold. You can claim a refund of the overpayment when you file your tax return.

Where Your Medicare Tax Money Goes

Medicare tax funds Part A of Medicare, which covers inpatient hospital care, skilled nursing facility care, hospice, and home health services. It does not fund Part B (doctor and outpatient services) or Part D (prescription drugs) — those are funded by general income tax revenue and beneficiary premiums.

When you turn 65, you become may be able to access for Medicare if you have worked and paid Medicare tax for at least 10 years (40 quarters). The money you paid during your working years goes into a trust fund that pays current beneficiaries' claims. You do not have a personal Medicare account that accumulates your contributions — it is a pay-as-you-go system.

If you become disabled or are diagnosed with end-stage renal disease before age 65, you may be able to enroll in Medicare earlier. Your prior Medicare tax payments count toward your may be able to access even if you have not yet reached retirement age.

Self-Employment and Medicare Tax

If you are self-employed, you pay both the employee and employer portions of Medicare tax. This is called Self-Employment Tax, and it totals 2.9% of your net self-employment income (after deducting half of the self-employment tax itself). You pay this when you file your annual tax return, usually by making quarterly estimated tax payments.

Self-employed people also pay the Additional Medicare Tax of 0.9% on net self-employment income above the same thresholds that apply to wage earners. You calculate and pay this on your tax return, not through payroll withholding.

You can deduct half of your self-employment tax as an adjustment to income on your tax return, which reduces your taxable income. This partially offsets the fact that you pay both the employee and employer sides.

Medicare Tax and Your Tax Return

Your employer reports the Medicare tax withheld on your Form W-2, which you receive by January 31 each year. The amount appears in Box 6 (Medicare wages and tips) and Box 7 (Medicare tax withheld). You do not need to do anything with this information unless you are checking that the amount is correct or you overpaid Additional Medicare Tax.

If you overpaid Additional Medicare Tax because you had multiple jobs or your employer made a mistake, you claim the refund on your tax return. You cannot get a refund of the standard 1.45% Medicare tax — that is a permanent contribution to the Medicare system.

Self-employed people report self-employment income and tax on Schedule SE and transfer the Medicare tax portion to their main tax return. The IRS uses this information to track your Medicare tax history for may be able to access purposes.
