Understanding Federal Income Tax
The United States uses a progressive tax system, meaning higher income is taxed at higher rates. Your income is divided into portions (brackets), and each portion is taxed at its respective rate. This means moving into a higher tax bracket doesn't cause ALL your income to be taxed at the higher rate — only the income within that bracket.
Key Concepts
- Marginal Tax Rate — The rate on your last dollar earned. This is the bracket you're "in."
- Effective Tax Rate — Your actual average tax rate across all brackets. Always lower than your marginal rate.
- Adjusted Gross Income (AGI) — Your total income minus above-the-line deductions like 401(k) and HSA contributions.
- Taxable Income — AGI minus the standard deduction or itemized deductions. This is what's actually taxed.
💡 Pro Tip
If your taxable income is close to a bracket threshold, contributing more to a 401(k) or traditional IRA can drop you into a lower bracket and save significantly on taxes.
❓ Income Tax FAQ
Your tax bracket is determined by your filing status and taxable income (income after deductions). For 2026, a single filer with taxable income of ,000 is in the 22% bracket. But remember, only income above ,475 is taxed at 22% — your first ,925 is taxed at 10%, and income from ,926-,475 is taxed at 12%.
Take whichever is higher. The 2026 standard deduction is ,700 (single) or ,400 (married filing jointly). Most taxpayers benefit from the standard deduction. You should itemize only if your total deductions (mortgage interest, state/local taxes up to ,000, charitable donations, medical expenses above 7.5% of AGI) exceed the standard deduction.
The State and Local Tax (SALT) deduction is capped at ,000 (,000 for married filing separately). This includes state income taxes, property taxes, and local taxes combined. This cap was introduced by the Tax Cuts and Jobs Act and significantly impacts taxpayers in high-tax states like California, New York, and New Jersey.
This calculator focuses on federal income tax and FICA (Social Security + Medicare). State income tax rates vary significantly — from 0% in states like Texas, Florida, and Nevada to over 13% in California. Your total tax burden includes federal, state, and local taxes combined.
