The US uses a progressive tax system — you don't pay your top bracket rate on all your income. If you're in the 22% bracket, only the income above the 12% threshold is taxed at 22%. Your effective rate is always lower than your marginal rate. The calculator above shows exactly how much of your income falls into each bracket.
The U.S. has a progressive tax system, meaning different portions of your income are taxed at different rates. In 2025, the federal brackets range from 10% on the lowest income to 37% on income above $626,350 (single filers). Critically, these are marginal rates — you only pay the higher rate on income within that bracket, not on all your income. A single filer with $100,000 in taxable income does not pay 22% on all $100,000. They pay 10% on the first $11,925, 12% on the next $36,550, and 22% on the remaining $51,525.
This distinction between marginal rate (the rate on your last dollar of income) and effective rate (your average rate across all income) is one of the most misunderstood concepts in personal finance. Knowing your effective rate tells you what you actually paid; knowing your marginal rate tells you the tax cost of earning additional income or the value of additional deductions.
Before calculating your tax bracket, you subtract either the standard deduction or itemized deductions from your gross income to arrive at taxable income. For 2025, the standard deduction is $15,000 for single filers and $30,000 for married filing jointly. Most Americans take the standard deduction because their itemizable expenses (mortgage interest, state and local taxes capped at $10,000, charitable contributions) don't exceed it. If they do exceed it, itemizing saves more. The decision is mathematical: itemize if your deductions exceed the standard deduction; otherwise take the standard.
Long-term capital gains (profits on assets held more than one year) are taxed at preferential rates: 0% for most middle-income earners, 15% for most, and 20% for top earners. These rates are significantly lower than ordinary income tax brackets. Short-term capital gains (assets held one year or less) are taxed as ordinary income at your marginal rate. This distinction has enormous planning implications: holding investments for more than a year before selling reduces your tax rate on gains from 22–37% down to 0–15% for most investors.
Contributing to a traditional 401(k) or IRA reduces taxable income dollar-for-dollar at your marginal rate — a significant benefit for high earners. A $23,500 401(k) contribution at a 22% marginal rate saves $5,170 in federal taxes. Health Savings Accounts (HSAs) offer a triple tax benefit: deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses. Tax-loss harvesting — selling investments at a loss to offset capital gains — is another common strategy in taxable brokerage accounts. Timing large income events (Roth conversions, asset sales) to lower-income years can also meaningfully reduce lifetime tax burden.
Federal taxes are only part of the picture. Most states have their own income taxes, ranging from 0% (no state income tax in Texas, Florida, Nevada, and several others) to over 13% in California. State taxes use different bracket structures and don't necessarily conform to federal definitions of income or deductions. High-income earners in high-tax states like California, New York, and New Jersey may face combined federal and state marginal rates above 50%. This is why state of residency is a significant financial planning variable for high earners and retirees.
