Your tax rate depends on your income, filing status, and what kind of income you earned
Your tax rate is the percentage of your income that goes to federal, state, or local taxes. The United States uses a progressive tax system, which means the rate increases as your income increases — you do not pay the same percentage on every dollar you earn. The rate that applies to your last dollar of income is called your marginal tax rate. The rate you pay on your entire income, averaged out, is called your effective tax rate. These are two different numbers, and understanding which one matters for your situation is the first step.
Your tax rate also depends on your filing status — whether you file as single, married filing jointly, head of household, or another category — because the income brackets that determine your rate are different for each status. A married couple filing jointly pays tax on a wider income range at the lowest rates than a single filer does, which is why filing status changes your rate even if your income stays the same.
Key Takeaways
- The IRS publishes tax brackets every year that show which rate applies to each chunk of your income based on your filing status.
- Your marginal rate is what you pay on your last dollar of income; your effective rate is your total tax divided by your total income.
- Self-employed people and people with investment income may owe different rates than people who earn only wages.
- Your state and local tax rates are separate from your federal rate and vary by where you live and work.
How federal tax brackets work
The IRS divides income into brackets, and each bracket has its own rate. For 2024, the federal brackets for a single filer are 10%, 12%, 22%, 24%, 32%, 35%, and 37%. If you earn $50,000 as a single person, you do not pay 22% on all of it. Instead, you pay 10% on the first chunk (roughly $11,000), then 12% on the next chunk, then 22% on the remainder. This is why your effective rate — the total tax you owe divided by your total income — is always lower than your marginal rate.
The IRS adjusts these brackets every year for inflation, so the income ranges change annually. The brackets for married filing jointly are roughly double those for single filers, and head of household brackets fall in between. You can find the current brackets on the IRS website or on your tax software when you file.
The difference between marginal and effective tax rate
Your marginal tax rate is the rate you pay on your last dollar of income. If you are a single filer in 2024 and earn $50,000, your marginal rate is 22% — that is the bracket your last dollar falls into. But your effective rate is lower, because you paid 10% and 12% on the earlier chunks. To find your effective rate, divide your total tax by your total income. If you owe $5,500 on $50,000 of income, your effective rate is 11%.
Your marginal rate matters when you are deciding whether to earn more income or take a deduction. If you are in the 22% bracket and you earn an extra $1,000, you will owe roughly $220 in federal tax on it. If you donate $1,000 to charity and can deduct it, you save roughly $220 in tax. Your effective rate does not change the math on that decision — your marginal rate does.
Self-employed and investment income rates
If you are self-employed, you owe income tax at the same rates as anyone else, but you also owe self-employment tax — a 15.3% tax that covers Social Security and Medicare. This is in addition to your income tax, not instead of it. You pay half of it yourself and the other half is treated as a business expense, but the full 15.3% is your responsibility. This makes your effective rate higher than a wage earner's at the same income level.
Long-term capital gains — profit from selling an investment you held for more than a year — are taxed at lower rates than ordinary income: 0%, 15%, or 20% depending on your income and filing status. may have access to dividends from stocks are also taxed at these rates. Short-term capital gains — profit from selling an investment you held for a year or less — are taxed as ordinary income at your regular brackets. If you have both wage income and investment income, you may owe different rates on different parts of your total income.
State and local tax rates
Your state income tax rate is separate from your federal rate and varies by state. Some states have no income tax at all — Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, and Wyoming do not tax income. Other states have rates ranging from roughly 1% to over 13%, depending on your income and filing status. You can find your state's tax brackets on your state's revenue or taxation department website.
Some cities and counties also charge local income tax on top of state and federal tax. This is less common but does explore in parts of Ohio, Pennsylvania, Kentucky, Indiana, and a few other states. If you work in a different city or state than where you live, you may owe tax to both places, though most states have rules to prevent you from paying tax twice on the same income.
How to find your specific tax rate
The simplest way to find your federal tax rate is to use tax software or a tax preparer, who will calculate it based on your income and filing status. If you want to do it yourself, start with the IRS tax brackets for your filing status and the current year. Add up your income from all sources — wages, self-employment, capital gains, and anything else. Find which bracket your total income falls into. That is your marginal rate. Then calculate your total tax owed (or use a tax calculator on the IRS website) and divide by your total income to find your effective rate.
If you are an employee and want to know roughly what you will owe before you file, you can use the IRS tax withholding estimator on the IRS website. It asks about your income, filing status, and deductions, then tells you whether your employer is withholding the right amount. If you are self-employed, you can use the same tool to estimate your quarterly tax payments.
Why your tax rate matters for financial decisions
Knowing your marginal tax rate helps you make decisions about deductions, retirement contributions, and extra income. If you are in the 24% bracket and you contribute $5,000 to a traditional IRA, you reduce your taxable income by $5,000, which saves you roughly $1,200 in federal tax. If you are in the 12% bracket, the same contribution saves you roughly $600. The higher your marginal rate, the more valuable a deduction is.
Your effective rate tells you what percentage of your total income actually goes to federal tax. This is useful for budgeting and understanding your take-home pay, but it does not change the math on individual decisions about deductions or extra income — your marginal rate does that.
Frequently Asked Questions
Is my tax rate the same every year?
No. The IRS adjusts tax brackets for inflation annually, so the income ranges that fall into each bracket change every year. Your marginal rate might stay the same even if your income increases, or it might move to a higher bracket. Your effective rate changes whenever your income or tax situation changes.
Why do I owe more tax than my tax rate suggests?
You may owe self-employment tax, which adds 15.3% on top of your income tax if you are self-employed. You may also owe alternative minimum tax if you have a high income with significant deductions. Or your employer may not have withheld enough from your paycheck, so you owe the difference when you file.
Can I lower my tax rate?
You cannot change the tax brackets themselves, but you can lower your taxable income through deductions and retirement contributions, which moves you into a lower bracket or reduces the income subject to tax. You can also claim tax credits, which directly reduce the tax you owe. A tax preparer or software can show you which options explore to your situation.
What is the difference between tax rate and tax bracket?
A tax bracket is a range of income with a specific rate attached to it. A tax rate is the percentage you pay on income in that bracket. For example, the 22% bracket for single filers in 2024 covers income from roughly $11,000 to $44,725. If your income falls in that range, 22% is your marginal rate.
