Understanding your government paycheck involves navigating federal, state, and local taxes, as well as other deductions that impact your take-home pay. This guide explains the key components of paycheck calculations, how taxes are determined, and official resources to ensure accuracy.

Federal Income Tax

Federal income tax is withheld from your paycheck based on your earnings, filing status, and allowances claimed on IRS Form W- U.S. uses a progressive tax system, meaning higher income levels are taxed at higher rates. For 2025, tax brackets range from 10% to 37%, depending on income and filing status (e.g., single, married filing jointly). The IRS provides detailed withholding tables to calculate the exact amount employers deduct. To estimate your federal tax, multiply your taxable income by the applicable rate after accounting for deductions and credits. For official guidance, visit the IRS Publication 15.

Social Security and Medicare Taxes

These are mandatory payroll taxes under the Federal Insurance Contributions Act (FICA). Social Security tax is of your wages, up to a 2025 wage base limit (projected around $168,600, subject to annual adjustment). Medicare tax is on all wages, with an additional for high earners (above $200,000 for single filers). Employers match these contributions. For details, see the Social Security Administration’s wage base update.

State and Local Income Taxes

State income taxes vary widely. Some states, like Texas and Florida, have no income tax, while others, like California, have rates up to Local taxes may also apply in certain cities or counties. Calculations depend on your state’s tax brackets, exemptions, and credits. Employers withhold based on your state W-4 form or equivalent. Check your state’s revenue department website for specifics, such as the California Franchise Tax Board or New York State Department of Taxation.

Other Deductions

Beyond taxes, paychecks may reflect deductions for health insurance premiums, retirement contributions (e.g., 401(k)), and wage garnishments. These vary by employer and employee elections. Pre-tax deductions, like health savings accounts, reduce taxable income, while post-tax deductions do not. Review your pay stub to understand specific withholdings.

How Paycheck Calculations Work

Employers calculate your paycheck by starting with gross pay, subtracting pre-tax deductions, applying federal and state tax withholdings, and then subtracting FICA taxes and post-tax deductions. The result is your net pay. Accurate W-4 forms are critical to avoid over- or under-withholding. The IRS offers a Tax Withholding Estimator to help adjust your withholdings.

Official Resources and Tools

For precise calculations, use government-provided tools. The IRS and state tax agencies offer withholding calculators, while the Social Security Administration clarifies FICA contributions. Always cross-reference with official sources to ensure compliance with current tax laws.
