2026 FICA Tax Rate

The official 2026 Social Security and Medicare tax rates, the Social Security wage base, and the Additional Medicare Tax thresholds — with a calculator for your own FICA tax.

For 2026, FICA is 6.2% Social Security tax (employee and employer each; 12.4% total if self-employed) on wages up to the $184,500 wage base, plus 1.45% Medicare tax (2.9% self-employed) with no wage cap. An extra 0.9% Additional Medicare Tax applies above $200,000 (single) or $250,000 (married filing jointly) of wages or self-employment income.

FICA rates and thresholds, 2026 — Social Security Administration, Contribution and Benefit Base; Additional Medicare Tax IRC §3101(b)(2) (Additional Medicare Tax, not indexed)
Item2026
Social Security (OASDI) tax rate — employee and employer, each 6.2%
Social Security (OASDI) tax rate — self-employed, both halves 12.4%
Social Security wage base (maximum taxable earnings) $184,500
Maximum employee Social Security tax$184,500 × 6.2% $11,439
Medicare (HI) tax rate — employee and employer, each 1.45%
Medicare (HI) tax rate — self-employed, both halves 2.9%
Additional Medicare Tax rate 0.9%
Additional Medicare Tax threshold — single, head of household, married filing separately $200,000
Additional Medicare Tax threshold — married filing jointly $250,000

FICA has two parts. Social Security tax stops once your wages for the year pass the $184,500 wage base — the most an employee pays in 2026 is $11,439, or $22,878 if you are self-employed and pay both halves. Medicare tax has no wage cap at all, and the Additional Medicare Tax layers 0.9 points on top once your wages or self-employment income (not your total household income) cross the threshold for your filing status — a threshold that has never been adjusted for inflation since it took effect in 2013 (IRC §3101(b)(2) (Additional Medicare Tax, not indexed)). An employer withholds the Additional Medicare Tax once your wages from that one employer cross $200,000, regardless of filing status; you reconcile the correct amount on Form 8959.

Your 2026 FICA tax

Paid tool Deciding between pre-tax contributions now and Roth conversions later is a multi-year bracket problem: every dollar deferred today has to come out later, in a year whose bracket and Medicare surcharge you are also choosing. The Roth Conversion Planner works that schedule: how much to convert in each year from now to your plan end age, the federal and state tax it costs, the IRMAA tier that year’s MAGI sets two years later, and the ACA subsidy it affects — set beside the same years with no conversions at all, and downloadable as a PDF you keep. A planning tool, not advice: the numbers move when your assumptions do. Build my conversion schedule — Personal PRO ($49) → See what is included, and price this year free, first →

FICA is withheld the same way every paycheck — what varies is how much of your retirement income triggers it at all. QuantCalc runs your whole retirement — withdrawals, taxes, Medicare surcharges — year by year, on the 2026 figures above.
