ProPublica has reported extensively about taxes, the IRS Free File program and the IRS. Specifically, the ways in which the for-profit tax preparation industry — companies like Intuit (TurboTax), H&R Block and Tax Slayer — has lobbied for the Free File program, then systematically undermined it with evasive search tactics and confusing design. These companies also work to fill search engine results with tax “guides” that sometimes route users to paid products.

What is a tax bracket?

The federal government taxes people based on how much they make each year. Seven tax brackets — based on income ranges — determine how much you pay:

Federal Tax Brackets by Adjusted Income

The rate that a single, nonmarried filer will pay for federal income tax.

Tax rate Single (not married)
10% $0 to $9,875
12% $9,876 to $40,125
22% $40,126 to $85,525
24% $85,526 to $163,300
32% $163,301 to $207,350
35% $207,351 to $518,400
37% $518,401 and above

What are the filing categories for income tax brackets?

In addition to those brackets, there are four main categories, also known as “statuses,” that affect how you are taxed:

  • Single filers: unmarried.
  • Married, filing jointly: couples filing together.
  • Married, filing separately.
  • Head of household: unmarried, live with a qualifying child.

Together, the categories and brackets look like this:

Federal Tax Brackets by Adjusted Income

Income tax brackets for each category of tax filers.

Tax rate Single Married, filing jointly* Married, filing separately Head of household
10% $0 to $9,875 $0 to $19,750 $0 to $9,875 $0 to $14,100
12% $9,876 to $40,125 $19,751 to $80,250 $9,876 to $40,125 $14,101 to $53,700
22% $40,126 to $85,525 $80,251 to $171,050 $40,126 to $85,525 $53,701 to $85,500
24% $85,526 to $163,300 $171,051 to $326,600 $85,526 to $163,300 $85,501 to $163,300
32% $163,301 to $207,350 $326,601 to $414,700 $163,301 to $207,350 $163,301 to $207,350
35% $207,351 to $518,400 $414,701 to $622,050 $207,351 to $311,025 $207,351 to $518,400
37% $518,401 and above $622,051 and above $311,026 and above $518,401 and above
*Qualifying widows or widowers are their own category, with the same income brackets as those who are married and filing jointly.

So, how do tax brackets work?

If you look at the table above, you might assume that you are simply taxed at one flat rate for all of your income. But it’s more complicated than that.

The U.S. has what’s called a progressive tax system. What that really means is that the amount you get taxed progresses with the amount of money you make — even within the tax brackets outlined above.

Example: Let’s say you’re a single filer, and you bring in a taxable income of $20,000. You would fall into the 12% tax bracket, but you wouldn’t simply be taxed 12%. Instead, you would get taxed at the lowest rate for the first $9,875 you make and at higher rates for the money you make above that.

In other words, you would be taxed in two different tax brackets: $0 to $9,875 and $9,876 to $40,125. For the first $9,875 you make, you are only taxed 10%. The remaining $10,125 you make is taxed at the next tax bracket level of 12%. So you would owe $988 for the first bracket and $1,215 for the second bracket.

What are the differences between state and federal tax brackets?

The above chart shows federal income tax brackets. Many states also have their own, separate tax brackets. Each state has its own rules, but they generally tax income at lower rates than the federal government. Most states have a progressive tax structure similar to the federal one. There are some exceptions though.

Seven states do not tax income at all:

  • Alaska
  • Florida
  • Nevada
  • Texas
  • South Dakota
  • Washington
  • Wyoming

Tennessee and New Hampshire don’t tax income from wages but do tax some income from investments.

Nine states tax income at one flat rate, no matter how much you make:

  • Colorado
  • Illinois
  • Indiana
  • Kentucky
  • Massachusetts
  • Michigan
  • North Carolina
  • Pennsylvania
  • Utah

What tax bracket am I in?

To determine your tax bracket, you need to know your taxable income in 2020. This involves figuring out two things: your income and your tax deductions.

  • Income: Essentially all income is taxable income. This includes your salary, wages, tips, any payment for freelance work, sales from real estate, unemployment benefits over $10,200 and more. (It also includes capital gains, which can be taxed at different rates depending on whether they are short or long term, and on what your income is).

Once you’ve determined your total income, you can generally subtract any deductions to arrive at your taxable income. See the chart above to find out where it places you.

What is the standard deduction?

The most-used tax deduction is the standard deduction, which is a no-questions-asked amount that you can subtract from your income, lowering the amount of income on which you have to pay taxes. Before claiming the standard deduction, make sure you understand the rules — for example, you can’t deduct home mortgage interest if you are also claiming the standard deduction. (For your 2020 taxes, you can deduct up to $300 in charitable donations in addition to taking the standard deduction, thanks to the CARES Act.)

Example: Let’s take a single person whose only income is from their salary of $32,000. If they only take the standard $12,400 deduction, they will have a taxable income of roughly $20,000. That means they’ll fall into the 12% bracket.

Do I have to pay taxes on unemployment benefits I received?

Unemployment insurance counts as income and is taxable. But thanks to President Joe Biden’s March 2021 stimulus law, the first $10,200 of unemployment income you received in 2020 does not get taxed for earners who made less than $150,000.

You can see if you need to pay taxes on your unemployment benefits using a tool on the IRS website.

What is an IRS tax audit?

An IRS audit is a review of a person’s tax filing by an IRS employee to make sure everything was done correctly. Sometimes, you’ll be chosen randomly, but usually something or someone will make your return stand out, and that causes leads to it being flagged for an audit.

This is important: If you’re being audited, you will find out via mail — never over the phone.

You might also hear from the IRS via a tax notice, which is usually less serious and could be for any number of reasons, like verifying your identity or the identity of your dependents or correcting a mathematical error.

How far back can the IRS audit?

The IRS can include the past three filing years in a tax audit. However, the agency can look further back if it identifies a major error. Typically it does not look back further than six years.

Who gets audited?

Taxpayers with household income between $50,000 and $100,000 are audited the least.

As ProPublica has reported, the IRS has seen its budget slashed year over year (though it got a bump in funding in the March 2021 stimulus bill), and its ability to audit the wealthy and corporations has also suffered. These days, the top-earning 1% of taxpayers are audited at about the same rate as those who claim the earned income tax credit (EITC), a group that has an average household income of $20,000 a year.

A 2019 analysis found that a rural county in the Mississippi Delta was audited at a higher rate than any other county in America, despite the fact that more than a third of its mostly African American population is below the poverty line. Also, the five counties with the highest audit rates are all rural, predominantly African American counties in the Deep South.

“Those struggling to make ends meet are being unfairly audited while the fortunate few dodge taxes without consequence,” Sen. Ron Wyden, D-Ore., the ranking member on the Senate Finance Committee, told ProPublica in 2018.

Did Trump’s tax plan make new U.S. tax brackets?

The short answer is no.

But Trump’s tax plan did change the percentage at which you are taxed within the tax brackets. In most cases, it lowered the amount people would be taxed in each bracket, except for the lowest bracket, which stayed the same at 10%. The changes are set to expire in 2025, at which point Congress will have to take up the tax law again or much of it will go back to what it was before 2018.

The tax brackets change every year a tiny bit to keep pace with inflation and increasing costs of living.
