US Federal Tax Brackets 2025: Every Rate Explained

Updated March 22, 2026 · 7 min read

Every year the IRS adjusts the federal income tax brackets for inflation, and 2025 is no different. The rates themselves haven't changed — there are still seven of them — but the income thresholds have shifted upward slightly. That's good news: it means you can earn a little more before bumping into the next bracket.

Here's a no-nonsense guide to exactly how much federal income tax you'll owe in 2025, with tables, a worked example, and a quick explainer on the stuff most people get wrong.

2025 federal tax brackets: single filers

Tax RateTaxable Income
10%$0 – $11,925
12%$11,926 – $48,475
22%$48,476 – $103,350
24%$103,351 – $197,300
32%$197,301 – $250,525
35%$250,526 – $626,350
37%Over $626,350

2025 federal tax brackets: married filing jointly

Tax RateTaxable Income
10%$0 – $23,850
12%$23,851 – $96,950
22%$96,951 – $206,700
24%$206,701 – $394,600
32%$394,601 – $501,050
35%$501,051 – $751,600
37%Over $751,600

Notice the married-filing-jointly brackets are roughly double the single filer brackets for most rates. That's by design — it means two spouses earning similar incomes don't get penalized just for being married (at least at most income levels).

How marginal tax rates actually work

This is the single biggest thing people misunderstand about taxes. If you're in the 22% bracket, you are not paying 22% on your entire income. You're only paying 22% on the portion that falls within that bracket.

Think of it like filling up buckets. Your first bucket (10%) fills up to $11,925. Once that's full, the overflow spills into the 12% bucket, and so on. Each dollar only gets taxed at the rate of the bucket it lands in.

This is what "marginal" means — your marginal rate is the tax rate on your last dollar of income. Your actual overall rate (what you really pay as a percentage of total income) is called your effective tax rate, and it's always lower than your marginal rate.

The standard deduction: $15,000 (single) or $30,000 (married)

Before you even look at the brackets, subtract the standard deduction from your gross income. For 2025, that's:

The standard deduction is the IRS's way of saying "we won't tax you on this chunk of income." Most people take it instead of itemizing (which only makes sense if your mortgage interest, state taxes, charitable donations and other deductions add up to more than $15,000 or $30,000).

Worked example: single filer earning $75,000

Let's walk through the math step by step for someone earning $75,000 as a single filer in 2025.

Step 1: Subtract the standard deduction

$75,000 minus $15,000 = $60,000 in taxable income.

Step 2: Apply each bracket

Step 3: Add it up

$1,192.50 + $4,386.00 + $2,535.50 = $8,114 in federal income tax.

On a $75,000 salary, that works out to an effective tax rate of about 10.8% — a whole lot less than the 22% marginal bracket you're technically in. That's the power of marginal rates.

Effective tax rate vs. marginal tax rate

Let's make this crystal clear because it trips up almost everyone:

Your marginal rate matters when you're deciding whether to earn an extra dollar (like picking up overtime or a side gig). Your effective rate tells you the real overall bite the IRS is taking. Both are useful — just don't confuse them.

Don't forget about FICA taxes

Federal income tax isn't the only thing Uncle Sam takes out of your paycheck. You also owe FICA taxes, which fund Social Security and Medicare:

So for our $75,000 earner, FICA adds $4,650 (Social Security) plus $1,087.50 (Medicare) = $5,737.50 on top of the $8,114 in income tax. That's roughly $13,852 total in federal taxes, or about 18.5% of gross pay.

State income taxes are a whole separate thing

Everything above covers federal taxes only. Most states pile on their own income tax on top of that. Rates and rules vary wildly — California's top rate is 13.3%, while nine states charge no income tax at all:

If you live in one of those states, your federal tax bill is basically the whole story. Everyone else needs to factor in state taxes too.
