What a tax rate is and how it affects what you pay

A tax rate is the percentage of your income or the value of something you own that goes to federal, state, or local government. It is not a flat number — the rate you pay depends on what you earn, where you live, what you buy, and what type of tax applies. Understanding which rate applies to you is the first step to knowing how much you actually owe.

Tax rates come in two main shapes: marginal and effective. Your marginal rate is the percentage you pay on your next dollar of income — it is the bracket you fall into. Your effective rate is the average percentage you pay on all your income combined. These are almost never the same number, and that difference matters when you are planning.

Key Takeaways

  • Tax rates are percentages that vary by income level, location, and type of tax — there is no single rate that applies to everyone.
  • Marginal tax rates tell you what percentage you pay on your next dollar; effective rates show your average across all income.
  • Federal income tax uses brackets that increase with income, while sales tax, property tax, and state income tax rates vary by location.
  • Your actual tax bill depends on deductions, credits, and what state and city you live in, not just your income.
  • Tax rates change yearly for federal brackets and can shift when you move or buy property in a different jurisdiction.

Federal income tax brackets and marginal rates

The federal government uses a bracket system where different portions of your income are taxed at different rates. If you earn $50,000, you do not pay the same rate on all $50,000. Instead, the first portion is taxed at a lower rate, the next portion at a higher rate, and so on. The rate that applies to your highest dollar of income is your marginal rate.

Federal brackets change every year to account for inflation. For 2024, the federal marginal rates range from 10 percent to 37 percent depending on your income and filing status. A single person earning $47,000 might fall into the 22 percent bracket, meaning their next dollar is taxed at 22 percent — but their effective rate (the average across all their income) is lower, usually around 12 to 14 percent. The Internal Revenue Service publishes updated brackets each January on its website.

Your filing status matters: single, married filing jointly, married filing separately, and head of household all have different bracket thresholds. A couple earning $100,000 combined may pay less total tax than a single person earning $100,000, because the joint brackets are wider.

State and local income tax rates

Not all states charge income tax. Nine states — Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming, and New Hampshire (on dividends and interest only) — have no state income tax. The remaining 41 states and Washington, D.C., do charge income tax, and the rates vary widely.

State income tax rates range from about 1 percent to over 13 percent, depending on the state and your income level. Some states use a flat rate (everyone pays the same percentage), while others use brackets similar to federal tax. California, for example, uses brackets that go up to 13.3 percent for high earners. Many cities and counties also charge local income tax on top of state tax — New York City, for instance, adds another 3 to 4 percent for residents.

If you move to a different state or city, your tax rate changes when ready. A person earning $75,000 in Texas pays no state income tax, but the same person in California pays roughly 9 percent state tax plus any local tax. This is why location matters as much as income when calculating your total tax burden.

Sales tax and consumption taxes

Sales tax is a percentage added to purchases at the point of sale. Unlike income tax, which is based on what you earn, sales tax is based on what you spend. The rate varies by state and sometimes by city or county within a state.

State sales tax rates range from zero (in states like Oregon, Montana, New Hampshire, and Delaware) to over 7 percent. Local sales tax can add another 1 to 4 percent on top of the state rate. A purchase in Tennessee might be taxed at 9.55 percent (state plus local), while the same purchase in Oregon is not taxed at all. Some items are exempt — groceries, prescription medications, and clothing are often untaxed or taxed at a lower rate, depending on the state.

Online purchases are now subject to sales tax in most states, even if the seller is out of state. The rate applied is usually the rate where the buyer lives, not where the seller is located.

Property tax rates and how they are calculated

Property tax is charged by counties and municipalities based on the assessed value of real estate you own. The rate is expressed as a percentage of that assessed value, but the way it is calculated varies by location.

Property tax rates range from less than 0.3 percent of home value in some states (like Hawaii and Louisiana) to over 2 percent in others (like New Jersey and Illinois). A home worth $300,000 in New Jersey might owe $6,000 or more per year in property tax, while the same home in Hawaii might owe $900. The assessed value is not always the market value — assessors use different methods, and some states cap how much the assessed value can increase each year.

Property tax bills are usually due annually or in two installments, and the rate can change if your local government adjusts the tax levy or if your home is reassessed. Homeowners often receive a notice of assessment and have a window to appeal if they believe the value is wrong.

Payroll taxes and self-employment tax

If you work for an employer, you pay payroll taxes — Social Security and Medicare — at a combined rate of 7.65 percent on wages up to a certain threshold. Your employer matches this amount, so the total cost to the employer is 15.3 percent, though you only see your half deducted from your paycheck.

Social Security tax is 6.2 percent on earnings up to $168,600 (for 2024; this threshold changes yearly). Medicare tax is 1.45 percent on all wages with no cap. High earners pay an additional 0.9 percent Medicare tax on income above $200,000 (single) or $250,000 (married filing jointly).

If you are self-employed, you pay both the employee and employer portions of these taxes — 15.3 percent combined — on net business income. This is called self-employment tax. You can deduct half of it when calculating your adjusted gross income, which reduces your taxable income slightly.

Capital gains tax rates and investment income

Money you make from selling investments or property is taxed differently than wages. Capital gains — the profit when you sell something for more than you paid — are taxed at preferential rates if you held the asset for more than one year (long-term capital gains).

Long-term capital gains rates are 0 percent, 15 percent, or 20 percent depending on your income level — much lower than ordinary income tax rates. Short-term capital gains (assets held one year or less) are taxed as ordinary income at your marginal rate. Dividends from stocks are also taxed at capital gains rates if they are may have access to dividends.

State income tax also applies to capital gains in most states. Some states, like California, tax capital gains at the same rate as ordinary income, while others offer no special rate. This is why the state you live in affects how much you keep from investment profits.

How deductions and credits change your effective rate

Your effective tax rate is not determined by your marginal rate alone. Deductions reduce the income that is taxed, while credits reduce the tax you owe directly. Both lower what you actually pay.

The standard deduction for 2024 is $14,600 for single filers and $29,200 for married couples filing jointly. If you earn $50,000 and take the standard deduction, only $35,400 is taxable. Itemized deductions — mortgage interest, property taxes, charitable donations — can be higher than the standard deduction for some people. Tax credits like the Earned Income Tax Credit or Child Tax Credit reduce your bill dollar-for-dollar, making them more valuable than deductions.

A person earning $60,000 with two children might owe $4,000 in federal tax before credits, but after the Child Tax Credit of $2,000 per child, they owe only zero — or even receive a refund. This is why two people with the same income can owe very different amounts.

Frequently Asked Questions

What is the difference between marginal and effective tax rate?

Your marginal rate is the percentage you pay on your next dollar of income — it is the bracket you fall into. Your effective rate is your total tax divided by your total income, which is always lower because lower brackets explore to your first dollars earned. If you earn $50,000 and owe $6,000 in federal tax, your effective rate is 12 percent, but your marginal rate might be 22 percent.

Do I pay the same tax rate everywhere in the United States?

No. Federal income tax rates are the same nationwide, but state income tax rates vary from zero to over 13 percent, and local income tax adds more in some cities. Sales tax ranges from zero to over 9 percent depending on location. Property tax varies widely by county. Your total tax burden depends heavily on where you live.

Why do tax rates change every year?

Federal tax brackets are adjusted annually for inflation so that wage increases do not automatically push you into a higher bracket. State and local rates can change when governments adjust budgets or reassess property values. You should check current rates each year, especially if your income or location changes.

How does self-employment tax differ from payroll tax?

Employees pay 7.65 percent in payroll taxes (Social Security and Medicare), and employers match it. Self-employed people pay both portions — 15.3 percent total — on net business income. You can deduct half of it, which reduces your taxable income slightly, but the full amount is still owed.

Can I reduce my tax rate by taking deductions?

Deductions reduce your taxable income, which lowers the amount subject to tax, but they do not change your tax rate itself. If you earn $60,000 and take a $10,000 deduction, you pay tax on $50,000 instead. Your marginal rate stays the same, but your effective rate drops because less income is taxed.
