Net Pay = Gross Salary — Federal Tax — State Tax — FICA
Federal taxes use a progressive bracket system. FICA consists of a 6.2% Social Security tax (capped at a specific income limit) and a 1.45% Medicare tax.
모범 사례 및 필수 지침
- Understand Progressive Tax Brackets: Moving into a higher tax bracket only affects the income earned above that specific threshold, not your entire salary.
- Account for Pre-Tax Deductions: Contributions to a 401(k), HSA, or traditional IRA lower your taxable gross income, reducing your overall tax burden.
- Update Your W-4 Withholdings: If you receive a massive tax refund every year, you are giving the government a free loan. Adjust your withholdings to get more cash in your monthly paycheck.
