The US Has a Progressive Tax System
The US federal income tax is progressive — meaning higher earners pay a higher percentage of their income in taxes. But here's the critical nuance that confuses most people: you only pay the higher rate on the portion of income that falls within that bracket, not on your entire income.
Think of the tax brackets like buckets. You fill the lower buckets first, paying that bucket's rate, then overflow into the next bucket. Your entire income never gets taxed at your top rate.
2026 Federal Tax Brackets
Below are the 2026 federal income tax brackets for single filers. Married filing jointly brackets are roughly double these thresholds.
| Tax Rate | Single Filer Income | Married Filing Jointly |
|---|---|---|
| 10% | $0 – $11,925 | $0 – $23,850 |
| 12% | $11,926 – $48,475 | $23,851 – $96,950 |
| 22% | $48,476 – $103,350 | $96,951 – $206,700 |
| 24% | $103,351 – $197,300 | $206,701 – $394,600 |
| 32% | $197,301 – $250,525 | $394,601 – $501,050 |
| 35% | $250,526 – $626,350 | $501,051 – $751,600 |
| 37% | Over $626,350 | Over $751,600 |
These brackets apply to taxable income — not gross income
Before the brackets even apply, your gross income is reduced by adjustments (like 401k contributions), then by either the standard deduction or your itemized deductions. Only what remains is "taxable income" — the amount that actually gets run through the brackets.
A Real Example: $85,000 Salary
Let's walk through exactly how a single filer earning $85,000 is actually taxed for 2026:
Gross Income: $85,000
Less: 401(k) contribution (assume): -$6,000
Adjusted Gross Income (AGI): $79,000
Less: Standard Deduction (2026): -$15,000
Taxable Income: $64,000
Tax Calculation:
10% on first $11,925: $1,193
12% on $11,926–$48,475 ($36,549): $4,386
22% on $48,476–$64,000 ($15,524): $3,415
──────────────────────────────────────────
Total Tax: $8,994
Marginal Rate: 22% (rate on the last dollar earned)
Effective Rate: 10.6% (total tax ÷ gross income)
You paid 10.6% overall — NOT 22% on everything.

Marginal Rate vs. Effective Rate — Know the Difference
This is the most important tax concept to understand. These two rates are often confused, and that confusion leads to poor decisions.
| Term | Definition | Why It Matters |
|---|---|---|
| Marginal Rate | The tax rate on your next dollar of income | Used to evaluate whether a raise, bonus, or investment income is "worth it" |
| Effective Rate | Total tax paid ÷ gross income | Your true average tax rate — what you actually paid overall |
The "it'll push me into a higher bracket" myth
Many people fear earning more because they think a raise will push them into a higher bracket and they'll "pay more on everything." This is impossible. If your raise pushes you from the 22% to the 24% bracket, only the dollars above the bracket threshold are taxed at 24%. Every dollar below remains taxed at its original lower rate. A raise always increases your take-home pay — always.
Standard vs. Itemized Deductions
Before your income hits the brackets, you get to subtract either the standard deduction (a flat amount set by the IRS) or your itemized deductions (the sum of specific qualifying expenses). You claim whichever is larger.
| Filing Status | 2026 Standard Deduction |
|---|---|
| Single | $15,000 |
| Married Filing Jointly | $30,000 |
| Head of Household | $22,500 |
Common itemized deductions include: mortgage interest, state and local taxes (SALT, capped at $10,000), charitable contributions, and medical expenses exceeding 7.5% of AGI. The 2017 Tax Cuts and Jobs Act nearly doubled the standard deduction, meaning roughly 90% of filers now benefit from taking the standard deduction rather than itemizing.
Tax Credits vs. Tax Deductions — Which Is More Valuable?
Credits are almost always more valuable than deductions of the same dollar amount. A deduction reduces your taxable income (saving you your marginal rate × the deduction). A credit reduces your tax bill dollar-for-dollar.
$1,000 Deduction: Reduces taxable income by $1,000 Tax savings = $1,000 × 22% = $220 $1,000 Tax Credit: Reduces your tax bill directly by $1,000 Tax savings = $1,000 The credit saves you 4.5× more money.
7 Legal Ways to Reduce Your Tax Bill
Maximize pre-tax retirement contributions
Contributing to a traditional 401(k) or IRA reduces your taxable income dollar-for-dollar. At the 22% bracket, a $6,500 IRA contribution saves you $1,430 in federal tax. The 2026 401(k) limit is $23,500 ($31,000 if 50+).
Use an HSA (Health Savings Account)
HSA contributions are triple-tax advantaged: deductible going in, grow tax-free, and tax-free on qualifying medical withdrawals. The 2026 contribution limit is $4,150 (individual) / $8,300 (family).
Consider a Roth conversion in a low-income year
If you have a year of unusually low income, converting traditional IRA funds to a Roth IRA at a lower tax rate than you'll pay in retirement can save significantly over a lifetime.
Harvest tax losses in your investment portfolio
Tax-loss harvesting means selling investments at a loss to offset capital gains. You can deduct up to $3,000 in net capital losses against ordinary income per year, with excess losses carrying forward.
Claim every credit you qualify for
The Child Tax Credit ($2,000/child), Earned Income Tax Credit (up to $7,830 for families), and Child and Dependent Care Credit are among the most valuable and commonly missed credits. Check your eligibility every year.
Use flexible spending accounts (FSA)
Dependent care FSAs ($5,000/yr) and healthcare FSAs reduce your taxable wages. Unlike HSAs, FSA funds must generally be used within the plan year.
Adjust your W-4 withholding
Withholding too much gives the IRS an interest-free loan of your money. Withholding too little triggers a penalty. Use the IRS Tax Withholding Estimator (or our calculator below) to find the right withholding amount.
