The United States does not have one single tax rate
America's tax system uses progressive tax brackets, meaning the rate you pay depends on how much income you earn. The federal government taxes income at seven different rates, ranging from 10 percent to 37 percent. The rate you pay is not the same as everyone else's — it rises as your income rises, and it changes every year based on inflation adjustments.
Your actual tax burden also depends on your state, your filing status (single, married, head of household), and what kind of income you earn. A person making $50,000 in New York pays a different total tax than someone making $50,000 in Texas, because Texas has no state income tax and New York does. This is why "America's tax rate" is not a single number — it is a system with many moving parts.
Key Takeaways
- Federal income tax uses seven brackets ranging from 10 percent to 37 percent, and you only pay the higher rate on income that falls into that bracket, not on all your income.
- Your state income tax rate varies by state — some states have no income tax at all, while others charge up to 13 percent.
- Tax brackets adjust every year for inflation, so the income thresholds that determine which bracket you fall into change annually.
- Your filing status (single, married, head of household) determines which bracket thresholds explore to you.
- Self-employed people pay both the employee and employer portion of Social Security and Medicare taxes, totaling 15.3 percent on net earnings.
How federal income tax brackets actually work
The seven federal tax brackets for 2024 are 10 percent, 12 percent, 22 percent, 24 percent, 32 percent, 35 percent, and 37 percent. These are marginal rates, which means you do not pay 37 percent on your entire income if you fall into the top bracket. Instead, you pay 10 percent on the first portion of your income, then 12 percent on the next portion, and so on, up to 37 percent only on the income above the highest threshold.
For a single filer in 2024, the brackets work like this: you pay 10 percent on income up to $11,600, then 12 percent on income from $11,600 to $47,150, then 22 percent on income from $47,150 to $100,525, and so on. If you earn $60,000, you do not pay 22 percent on all of it — you pay 10 percent on the first $11,600, 12 percent on the next $35,550, and 22 percent only on the remaining $12,850. This structure means your effective tax rate (the actual percentage of your total income you pay in federal tax) is always lower than your marginal rate.
These bracket thresholds change every year. The Internal Revenue Service adjusts them for inflation, so the income level where each bracket begins shifts upward annually. This adjustment means that if your income stays the same but inflation rises, you might move into a higher bracket — a phenomenon called bracket creep.
State income tax rates vary widely
Nine states have no state income tax at all: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (which taxes only dividend and interest income). The remaining 41 states and Washington, D.C. charge state income tax, and the rates range from 1 percent in Colorado to 13.3 percent in California.
Some states use a flat tax rate — everyone pays the same percentage regardless of income. Colorado charges 4.4 percent, Illinois charges 4.95 percent, and Pennsylvania charges 3.07 percent. Other states use progressive brackets similar to the federal system, with rates that rise as income rises. New York's top rate is 10.9 percent, and Massachusetts charges 5 percent on most income but 12 percent on capital gains.
Your state tax rate also depends on whether you live in a state with local income taxes. Some cities and counties in states like Ohio, Pennsylvania, and Maryland charge additional local income tax on top of state tax. This means a resident of Columbus, Ohio might pay federal tax, Ohio state tax, and Columbus city tax all on the same income.
Self-employment tax is separate from income tax
If you are self-employed, you pay self-employment tax in addition to income tax. This covers Social Security and Medicare — the same programs that employers and employees split on a W-2 job. As a self-employed person, you pay both halves: 12.4 percent for Social Security (on earnings up to $168,600 in 2024) and 2.9 percent for Medicare (on all net earnings), plus an additional 0.9 percent Medicare tax if your net earnings exceed $200,000 for single filers.
This means self-employment tax totals 15.3 percent on most of your net business income, compared to the 7.65 percent that an employee pays on wages. You can deduct half of your self-employment tax when calculating your adjusted gross income, which provides some offset, but the burden is still higher than what a W-2 employee pays.
Capital gains and investment income have their own rates
Income from investments — stocks, bonds, real estate sales — is taxed differently than wages. Long-term capital gains, which are profits from assets you held for more than one year, are taxed at 0 percent, 15 percent, or 20 percent depending on your income level. These rates are lower than ordinary income tax rates, which is why investment income is often taxed more favorably than wages.
Short-term capital gains, from assets held one year or less, are taxed as ordinary income at your regular bracket rate. Dividends from stocks are also taxed as either ordinary income or long-term capital gains, depending on whether they are may have access to dividends. Interest income from bonds and savings accounts is taxed as ordinary income at your full bracket rate.
Some states tax capital gains differently than ordinary income. California taxes long-term capital gains as ordinary income, while Washington State has a capital gains tax of 7 percent on gains over $250,000. Understanding which type of income you have matters because the tax rate can differ significantly.
Payroll taxes fund Social Security and Medicare
Payroll taxes are separate from income tax. If you work as an employee, your employer withholds 6.2 percent of your wages for Social Security and 1.45 percent for Medicare, totaling 7.65 percent. Your employer also pays a matching 7.65 percent on your behalf, though you do not see this amount on your paycheck. These are not optional — they are mandatory for all W-2 employees.
The Social Security portion stops once you reach the wage cap, which is $168,600 in 2024. This means if you earn $200,000, you only pay Social Security tax on the first $168,600 of that income. Medicare tax continues on all wages above the cap, and high earners pay an additional 0.9 percent Medicare tax on wages over $200,000 (for single filers).
Your effective tax rate is lower than your marginal rate
Your effective tax rate is the total tax you pay divided by your total income. This is always lower than your marginal rate because of how brackets work. If you earn $75,000 as a single filer in 2024, your marginal rate is 22 percent (the rate on your last dollar of income), but your effective federal income tax rate is roughly 10 percent — meaning you pay about $7,500 in federal income tax, not $16,500.
Your effective rate also accounts for deductions and credits. If you take the standard deduction (which is $14,600 for single filers in 2024), you reduce your taxable income before any tax is calculated. If you have children or pay student loan interest, you may may have access to for credits or deductions that lower your tax further. These reduce your effective rate even more.
Frequently Asked Questions
What is the highest tax rate in America right now?
The highest federal income tax rate is 37 percent, which applies to single filers earning over $578,100 in 2024. However, this is a marginal rate — you only pay 37 percent on income above that threshold, not on your entire income. Your effective rate will be much lower. State income tax rates vary; California's top rate is 13.3 percent.
Do I pay taxes on all my income at my tax bracket rate?
No. You only pay your bracket rate on income that falls within that bracket. If you are in the 22 percent bracket, you pay 10 percent on the first portion of your income, 12 percent on the next portion, and 22 percent only on the portion that falls in the 22 percent bracket. This is why your effective rate is always lower than your marginal rate.
Why do tax brackets change every year?
The Internal Revenue Service adjusts tax brackets annually for inflation. This means the income thresholds that determine which bracket you fall into shift upward each year. Without this adjustment, inflation alone would push people into higher brackets even if their real income had not increased.
Do I have to pay both federal and state income tax?
It depends on your state. Nine states have no state income tax, so residents pay only federal tax. Everyone else pays both federal and state income tax. Some cities and counties also charge local income tax on top of state tax, so your total tax burden can include three layers.
Is self-employment tax the same as income tax?
No, they are separate. Self-employment tax covers Social Security and Medicare and totals 15.3 percent on net business income. Income tax is calculated on your taxable income using the federal brackets. You pay both if you are self-employed, plus any applicable state and local taxes.
