About this tool

Enter your yearly wages. The calculator applies Social Security at 6.2 percent up to the wage base and Medicare at 1.45 percent, plus the additional 0.9 percent Medicare tax over $200,000, and shows the matching employer share. Figures are for the 2026 tax year and can change. A guide only, check irs.gov or a tax professional.

What FICA is

FICA stands for the Federal Insurance Contributions Act. Social Security funds retirement and disability benefits, and Medicare funds health insurance for older adults. Employees and employers each pay 7.65 percent of wages up to the Social Security wage base of $184,500 in 2026.

Example

On $75,000 of wages, Social Security is $4,650 and Medicare is $1,088, a total of $5,738 or 7.65 percent. The employer pays the same amount again.

Not included

This is separate from federal and state income tax. The self-employed pay both halves, see the self-employment tax calculator.

最良の結果を得るためのヒント

結果を信頼する前にすべての項目を確認してください。数字がひとつ違うだけで答え全体が変わります。給与明細、請求書、証明書、契約書にある正確な数字を使い、計算した日付を控えておきましょう。税率、しきい値、ルールは随時変わるため、税金、手数料、法的な事柄については結果を概算とみなし、このページに記載された公式情報源で確認してください。シナリオは何度でも試せます。何も保存・送信されず、ページを再読み込みすると入力欄はクリアされます。
