Every year, the IRS adjusts the income thresholds for each tax bracket to account for inflation — a process called an "inflation adjustment" or "bracket indexing." For 2025, the IRS increased bracket thresholds by approximately 2.8% compared to 2024, which means more of your income is taxed at lower rates than last year.
Before we get to the numbers, there is one concept that trips up almost everyone: the difference between your marginal tax rate (the rate on your last dollar of income) and your effective tax rate (the actual percentage of your total income you pay in taxes). These are almost never the same number — and confusing them leads to bad financial decisions.

2025 Tax Brackets — Married Filing Jointly
These rates apply to couples filing jointly. Note that MFJ thresholds are exactly double the Single thresholds for most brackets — this eliminates the "marriage penalty" for most middle-income couples.
| Rate | Taxable Income |
|---|---|
| 10% | $0 – $23,850 |
| 12% | $23,850 – $96,950 |
| 22% | $96,950 – $206,700 |
| 24% | $206,700 – $394,600 |
| 32% | $394,600 – $501,050 |
| 35% | $501,050 – $751,600 |
| 37% | $751,600 – No limit |
Marginal vs. Effective Tax Rate
The Most Important Tax Concept Most People Get Wrong
The U.S. uses a progressive tax system. You do NOT pay your top bracket rate on all of your income. You pay each rate only on the portion of income that falls within that bracket. Think of it like filling buckets — each bucket gets filled at its own rate before the next one starts.
Example: Single filer with $80,000 taxable income in 2025
This person is "in the 22% bracket" — but they only pay 22% on the last $31,525 of their income. Their actual tax bill is $12,514, which is just 15.6% of their $80,000 income. This is why saying "I don't want a raise because it'll put me in a higher bracket" is a myth — a raise can never reduce your take-home pay under a progressive system.
2025 Standard Deduction
The standard deduction is subtracted from your gross income before tax brackets are applied. This is why the bracket thresholds above apply to taxable income, not your total salary. About 90% of Americans take the standard deduction rather than itemizing.

5 Legal Ways to Lower Your Tax Bracket
Contribute to a Traditional 401(k) or IRA
Every dollar you contribute to a Traditional 401(k) or IRA reduces your taxable income dollar-for-dollar. The 2025 401(k) contribution limit is $23,500 ($31,000 if age 50+). A $23,500 contribution at the 22% bracket saves you $5,170 in federal taxes.
Maximize an HSA (Health Savings Account)
If you have a high-deductible health plan, an HSA is the only triple-tax-advantaged account in existence: contributions are pre-tax, growth is tax-free, and withdrawals for medical expenses are tax-free. The 2025 contribution limit is $4,300 for individuals and $8,550 for families.
Harvest Tax Losses in Your Investment Portfolio
If you have investments that are down from what you paid, selling them "realizes" a loss that can offset capital gains — or up to $3,000 of ordinary income per year. This is called tax-loss harvesting and is one of the most underused strategies for investors.
Defer Income to Next Year
If you are self-employed or have control over when you receive income (bonuses, freelance payments), you can defer income into the next tax year if you expect to be in a lower bracket. This is especially powerful in a year when you expect significant income changes.
Bunch Charitable Deductions
Instead of donating $5,000 per year for two years, donate $10,000 in one year. This may push you over the standard deduction threshold, allowing you to itemize and capture a larger deduction. A Donor-Advised Fund makes this strategy easy to execute.
