Understanding Your Paycheck

Your gross pay (total earnings) is reduced by several deductions to arrive at net pay (take-home pay). Federal income tax is calculated based on your tax bracket and W-4 withholding elections. Social Security tax is 6.2% up to the annual wage base. Medicare tax is 1.45% with no limit. State and local taxes vary by location.

Tax Brackets Explained

The U.S. uses a progressive tax system — you do not pay the same rate on all your income. Only income within each bracket is taxed at that rate. For example, a single filer earning $50,000 pays 10% on the first $11,600, 12% on $11,601-$47,150, and 22% on $47,151-$50,000. Your effective tax rate is always lower than your marginal bracket.

Pre-Tax vs Post-Tax Deductions

Pre-tax deductions (401(k), health insurance, HSA, FSA) reduce your taxable income, saving you money on taxes. Post-tax deductions (Roth 401(k), life insurance, union dues) come out after taxes are calculated. Maximizing pre-tax deductions is one of the most effective ways to reduce your tax burden.

Optimizing Your Withholding

If you get a large tax refund each year, you are over-withholding and giving the government an interest-free loan. Adjust your W-4 to reduce withholding and increase take-home pay. If you owe taxes each year, increase withholding to avoid penalties. Use the IRS Tax Withholding Estimator to find the right balance.
