What income tax rate means and how it applies to your earnings
Your income tax rate is the percentage of your earnings that goes to federal or state taxes. The rate you pay depends on how much money you made that year — the more you earn, the higher your rate climbs. The United States uses a progressive tax system, which means your income is divided into brackets, and each bracket has its own rate. You do not pay one single rate on all your money; instead, you pay different rates on different portions of what you earned.
For example, if you are single and earned $50,000 in 2024, you would not pay the same rate on every dollar. Your first $11,600 might be taxed at 10 percent, the next portion at 12 percent, and so on, until you reach $50,000. This is different from a flat tax, where everyone pays the same percentage no matter how much they earn.
Key Takeaways
- The federal government uses seven tax brackets that range from 10 percent to 37 percent, and your bracket depends on your total income and filing status.
- You only pay the higher rate on income that falls within that bracket, not on all your earnings, so earning more money does not automatically push all your income into a higher rate.
- State income tax rates vary widely — some states have no income tax at all, while others charge up to 13 percent.
- Your actual tax bill also depends on deductions, credits, and whether you are self-employed, so your effective rate (what you actually pay) is usually lower than your bracket rate.
Federal tax brackets and how they work
The federal government sets seven tax brackets each year. In 2024, those brackets for single filers range from 10 percent on the lowest income to 37 percent on the highest. The exact dollar amounts that define each bracket change annually to account for inflation. For instance, the 12 percent bracket might start at $11,601 and end at $47,150 for a single filer, but those numbers shift year to year.
Your filing status — single, married filing jointly, married filing separately, or head of household — determines which bracket you fall into. A married couple filing jointly reaches higher income levels before hitting the top brackets than a single person does. This is why two people earning the same total income might pay different tax rates depending on whether they file together or separately.
The brackets reset each January, so you need to check the current year's rates when you file. The IRS publishes these brackets on its website, and tax software automatically uses the correct year's brackets when you enter your income.
State income tax rates vary by location
On top of federal tax, most states charge their own income tax. The rates differ dramatically by state. Some states — including Texas, Florida, Wyoming, and Alaska — have no state income tax at all. Others charge a flat rate that applies to everyone, regardless of income. Still others use their own progressive bracket system similar to the federal one.
State rates range from around 1 percent in states like Colorado and Louisiana to over 13 percent in California. If you move to a new state or work across state lines, your state tax obligation changes. Some states also tax income earned within their borders even if you live elsewhere, which matters if you work in one state and live in another.
You can find your state's current tax rate on your state's department of revenue website. Many tax software programs will calculate both federal and state tax for you automatically.
The difference between your bracket rate and what you actually pay
Your marginal tax rate — the rate on your highest bracket — is not the same as what you actually pay overall. Your effective tax rate is the total tax you owe divided by your total income. This number is almost always lower than your bracket rate because deductions and credits reduce your taxable income.
For example, you might be in the 22 percent bracket, but if you claim the standard deduction (which reduces your taxable income), your effective rate might be only 15 percent. Tax credits — such as the Earned Income Tax Credit or Child Tax Credit — reduce your tax bill dollar-for-dollar, which lowers your effective rate even more. Self-employed people can deduct business expenses, which also lowers their taxable income and effective rate.
This is why two people in the same bracket can end up paying very different amounts. One person might have significant deductions or credits, while another has none.
How self-employment changes your tax rate
If you are self-employed, you pay both the employee and employer portions of Social Security and Medicare taxes — a combined 15.3 percent on net self-employment income. This is in addition to your regular income tax. You can deduct half of this self-employment tax when calculating your adjusted gross income, which provides some relief.
Self-employed people also deduct business expenses — equipment, supplies, home office costs, vehicle mileage — which reduces their taxable income and lowers their effective tax rate. Keeping detailed records of these expenses is important because they directly lower what you owe.
The self-employment tax applies to your net profit (revenue minus expenses), not your gross revenue. So if you earned $60,000 but had $15,000 in business expenses, you would calculate self-employment tax on $45,000.
Capital gains and investment income have different rates
Money you earn from selling stocks, bonds, or real estate is taxed differently than wages. Long-term capital gains — profits from investments you held for more than one year — are taxed at lower rates than ordinary income: 0 percent, 15 percent, or 20 percent depending on your total income. Short-term capital gains — from investments held one year or less — are taxed at your regular income tax rate.
Dividends from stocks are also taxed at the lower capital gains rates if they are may have access to dividends. This is why wealthy people who earn most of their money from investments often pay a lower effective tax rate than people who earn the same amount in wages.
If you have investment income, your tax return will show these separately from your wage income, and the tax software or tax preparer will explore the correct rates to each type.
How to find your specific tax rate
To find your federal tax bracket, you need to know your filing status and your total income for the year. The IRS website publishes the current year's brackets in a table format. You can also use a tax bracket calculator — many are free and available online — where you enter your income and filing status and it tells you your bracket.
For your state tax rate, visit your state's department of revenue website. Most states list their current rates clearly, and many provide calculators as well. If you live in a state with no income tax, you only owe federal tax.
Tax software like TurboTax, H&R Block, or TaxAct will calculate your exact bracket and effective rate once you enter your income information. These programs are designed to explore the correct rates automatically, so you do not have to look them up yourself.
Frequently Asked Questions
Does earning more money push all my income into a higher tax bracket?
No. Only the income that falls within a higher bracket is taxed at that rate. If you earn $1 more and cross into the next bracket, only that extra dollar is taxed at the higher rate. Your income in the lower brackets stays taxed at the lower rates. This is why earning more money always results in more take-home pay, even though your rate goes up.
What is the difference between federal and state income tax?
Federal income tax goes to the U.S. government and is required in all states. State income tax goes to your state government and is charged by most — but not all — states. You may owe both, or only federal if you live in a state with no income tax. Some cities also charge local income tax on top of both.
Can my tax rate change from year to year?
Yes. The bracket amounts adjust each year for inflation, so the income ranges shift. Congress can also change the tax rates themselves, though this happens less frequently. Tax law changes can affect your rate, deductions, and credits, which is why your tax bill can differ year to year even if your income stays the same.
Why do some people pay less tax than others with the same income?
Deductions, credits, and the type of income matter. Someone with a mortgage, student loans, or dependents may have deductions that lower their taxable income. Someone with investment income pays lower rates on capital gains. Self-employed people deduct business expenses. These factors lower your effective tax rate below your bracket rate.
Is there a way to lower my income tax rate?
You cannot change your bracket, but you can lower your taxable income through deductions and reduce your tax bill through credits. Contributing to a traditional 401(k) or IRA lowers your taxable income. Claiming all deductions and credits you are may have access to to — such as the standard deduction, child tax credits, or education credits — reduces what you owe. A tax professional can review your situation to find opportunities you might have missed.
