What are the IRS tax brackets? What are the new federal tax brackets for 2023? Answers here

With March Madness soon drawing to a close, millions of Americans will turn their attention from NCAA brackets to tax brackets.

Every year, the Internal Revenue Service announces new tax brackets, tiers of income that are taxed at different rates under our nation's progressive tax system. Understanding tax brackets is key to predicting how much tax you owe.

Each tier of income is taxed at a progressively higher rate. You pay the lowest tax rate on the lowest tier of income, a slightly higher rate on the next-higher tier, and so on. The higher your taxable income, the higher your tax rate, but the highest rate applies only to the highest tier of income that you reach.

Tax brackets rise with inflation. The brackets for 2023, reflected on the tax return you file in 2024, are slightly higher than the ones for 2022.

How do tax brackets work?

Let's say you earned $75,000 in taxable income in 2023, and you're single. For the first $11,000 of that income, you'll pay the lowest 2023 tax rate, 10%, on that tier of income. For the tier of income between $11,001 and $44,725, you'll pay a 12% tax rate. For all of your income above $44,726, you'll pay tax at a much steeper rate, 22%.

There are seven tax brackets in all, each with a different tax rate.

The IRS uses inflation data to adjust tax brackets for the upcoming tax year. If you got a raise to keep up with inflation in 2023, you probably owe tax at roughly the same rate as in 2022, all else being equal. If your salary rose faster than inflation, you may have crept into a higher tax bracket. If your wages didn't keep up with inflation, you could top out in a lower bracket.

Head of household tax bracket

For tax purposes, the IRS generally defines a head of a household as a parent who pays for more than half of a household's expenses. Heads of household have higher income thresholds for each tax bracket than individual filers, to account for the additional costs they cover.

The head of household tax brackets for 2023 are:

37% on the portion of income above $578,100.
35% on the portion of income between $231,251 and $578,100.
32% on the portion of income between $182,101 and $231,250.
24% on the portion of income between $95,351 and $182,100.
22% on the portion of income between $59,851 and $95,350.

How can I lower my tax bracket?

There are many ways you can lower your tax bracket. If you're married, filing a joint return with your spouse could qualify you for a lower tax bracket. Or, depending on your income and circumstances, you may lower your tax bracket by filing an individual return.

Another way to lower your tax bracket is by contributing to a 401(k). This will lower your taxable income, which can put you in a lower bracket. If your employer doesn't offer a 401(k), contributions to a traditional Individual Retirement Account could help you qualify for a tax deduction, which could also lower your bracket.

You might also consider taking the standard deduction instead of itemized deductions, a choice that could put you in a lower bracket, depending on your financial situation.
