What Is Fed MWT EE on My Paycheck? The 1.45% Check
Fed MWT EE is the employee share of Medicare tax. What the abbreviation unpacks to, the 1.45% arithmetic you can verify in seconds and why it has no wage cap.
Fed MWT EE unpacks to Federal Medicare Withholding Tax, Employee. It is the Medicare half of FICA, and it is one of the few deductions on a pay stub you can verify with a single division.
The Arithmetic
The employee Medicare rate is 1.45% of Medicare taxable wages. Take the deduction, divide it by the Medicare wages shown on the stub, and you should get 0.0145. If you do not, the taxable wage figure is usually what is wrong rather than the rate, and that normally traces back to a pre-tax deduction being coded incorrectly.
Your employer pays a matching 1.45%. That share never appears as a deduction because it is not taken from your wages; some stubs show it in an employer contributions section for information only.
No Cap, Unlike Social Security
Social Security tax stops once wages reach the annual wage base. Medicare has no such ceiling: every dollar of covered wages is subject to the 1.45%. This is why high earners see their Social Security line disappear late in the year while the Medicare line continues unchanged.
The Additional Medicare Tax
Wages above a statutory threshold attract an extra 0.9% Additional Medicare Tax, withheld from the employee only with no employer match. Employers begin withholding it once your wages with them pass the threshold, which means the withholding does not always match your final liability if you hold more than one job or file jointly. The reconciliation happens on your return.
I cover the threshold mechanics and the cases where withholding and liability diverge in my explainer on Fed MWT EE for Online Paystub.
Different Labels, Same Tax
Payroll providers print this line in several ways: Fed MWT EE, Fed MED/EE, MED EE, Medicare EE. They all refer to the same 1.45% employee Medicare withholding. If your stub uses a label you have not seen before, apply the division test and you will know immediately what it is.
