Because the US uses a progressive tax system, being in the 24% marginal bracket does not mean all of your income is taxed at 24%—only the dollars above that bracket's threshold are taxed at 24%, while lower portions are taxed at 10%, 12%, and 22%. Your effective tax rate is the actual percentage of your total gross income paid in tax.
The Standard Deduction is a flat, no-questions-asked dollar amount subtracted from your Adjusted Gross Income based on your filing status. You should only itemize deductions (Schedule A) if the sum of your mortgage interest, state/local taxes (SALT), charitable donations, and qualifying medical expenses exceeds your Standard Deduction.
For W-2 employees, FICA comprises two taxes: the 6.2% Social Security tax applies only up to the annual OASDI wage base limit (earnings above the cap are exempt), while the 1.45% Medicare tax applies to all earned income with no cap—plus an Additional Medicare Tax of 0.9% on wages exceeding $200,000 (Single) or $250,000 (Married Filing Jointly).
Your filing status determines both your Standard Deduction amount and the income thresholds for each tax bracket. Married Filing Jointly doubles the Standard Deduction and widens the lower tax brackets compared to Single filers, while Head of Household provides a larger deduction and more favorable brackets for unmarried taxpayers supporting a qualifying dependent.
Contributions to a Traditional 401(k), traditional IRA, or Health Savings Account (HSA) reduce your Adjusted Gross Income (AGI) dollar-for-dollar off the top of your highest marginal tax bracket. If you are in the 24% bracket, contributing $10,000 to a pre-tax 401(k) immediately lowers your federal income tax bill by $2,400.
Your marginal tax rate is the tax bracket applied to your highest dollar of earnings (e.g. 22%). Your effective tax rate is your total actual taxes paid divided by your total income (e.g. 14.8%), which is always significantly lower due to the standard deduction and lower tiered brackets.
Social Security tax is capped at the annual wage base limit of $168,600. Earnings above this threshold are no longer subject to the 6.2% Social Security tax. However, the 1.45% Medicare tax applies to all earnings without a cap.
