How to Use This Calculator
This calculator is designed to be used by anyone — no tax knowledge required. Here's how to get the most out of it:
Step 1 — Enter your income
Type in your gross income — that's the total amount you earned before anything is taken out. If you have a W-2 job, look at Box 1. If you freelance, add up all the amounts on your 1099s. If you have both, add them together.
Step 2 — Choose your filing status
Your filing status affects your tax brackets and standard deduction. Pick the one that applies to you:
- Single — unmarried, or legally separated as of December 31
- Married Filing Jointly — married and filing one return together (usually results in lower taxes)
- Married Filing Separately — married but filing individual returns
- Head of Household — unmarried with a qualifying child or dependent
Step 3 — Choose standard or itemized deductions
For most people, the standard deduction is the better choice and is automatically applied. If you have significant mortgage interest, high state taxes, or large charitable donations, click "I'll Itemize" and enter your total itemized deductions.
Not sure which to use? The standard deduction is $14,600 if you're single, $29,200 if you're married. If your itemized deductions add up to more than that, itemizing saves you money. Most people take the standard deduction — it's simpler and often larger.
Step 4 — Add retirement contributions (optional)
Switch to the Detailed tab to add pre-tax retirement contributions like a 401(k) or Traditional IRA. Every dollar you contribute reduces your taxable income dollar-for-dollar, often lowering your bracket.
Step 5 — Read your results
The results panel shows your estimated tax bill, effective tax rate, marginal (top) bracket, and take-home pay. The bracket bar at the bottom shows visually how your income is distributed across the 7 federal tax brackets.
💡 Pro tip: Try entering your 401(k) contribution in the Detailed tab. You'll often see your bracket drop, sometimes saving you hundreds of dollars just by increasing your retirement savings by a small amount.
2026 Federal Income Tax Brackets
The United States uses a progressive tax system, which means different portions of your income are taxed at different rates. You only pay the higher rate on income that falls within that bracket — not on everything you earn.
Here's an important thing most people get wrong: being in the 22% bracket does NOT mean you pay 22% on all your income. You pay 10% on the first chunk, 12% on the next chunk, and only 22% on the income that falls within that bracket.
2026 Tax Brackets — Single Filers
| Rate | Taxable Income Range | Tax on This Portion |
|---|---|---|
| 10% | $0 – $11,600 | 10% of taxable income |
| 12% | $11,601 – $47,150 | $1,160 + 12% over $11,600 |
| 22% | $47,151 – $100,525 | $5,426 + 22% over $47,150 |
| 24% | $100,526 – $191,950 | $17,169 + 24% over $100,525 |
| 32% | $191,951 – $243,725 | $39,111 + 32% over $191,950 |
| 35% | $243,726 – $609,350 | $55,679 + 35% over $243,725 |
| 37% | Over $609,350 | $183,648 + 37% over $609,350 |
2026 Tax Brackets — Married Filing Jointly
| Rate | Taxable Income Range | Tax on This Portion |
|---|---|---|
| 10% | $0 – $23,200 | 10% of taxable income |
| 12% | $23,201 – $94,300 | $2,320 + 12% over $23,200 |
| 22% | $94,301 – $201,050 | $10,852 + 22% over $94,300 |
| 24% | $201,051 – $383,900 | $34,337 + 24% over $201,050 |
| 32% | $383,901 – $487,450 | $78,221 + 32% over $383,900 |
| 35% | $487,451 – $731,200 | $111,357 + 35% over $487,450 |
| 37% | Over $731,200 | $196,670 + 37% over $731,200 |
What Is the Standard Deduction?
The standard deduction is a flat dollar amount the IRS lets you subtract from your income before calculating your taxes. It's the government's way of saying "we won't tax this portion of what you earned."
2026 Standard Deduction Amounts
| Filing Status | Standard Deduction | Age 65+ Addition |
|---|---|---|
| Single | $14,600 | +$1,950 |
| Married Filing Jointly | $29,200 | +$1,550 per spouse |
| Married Filing Separately | $14,600 | +$1,550 |
| Head of Household | $21,900 | +$1,950 |
You can choose between the standard deduction or itemized deductions — whichever is larger reduces your taxes more. Most people (about 90%) use the standard deduction because it's simple and usually larger.
When should you itemize? Consider itemizing if you have a large mortgage (the interest may be deductible), you paid significant state income or property taxes (up to $10,000 combined), you made large charitable contributions, or you had significant unreimbursed medical expenses exceeding 7.5% of your adjusted gross income.
Effective Rate vs. Marginal Rate — What's the Difference?
This is one of the most misunderstood parts of the tax code. Here's the clear explanation:
Marginal tax rate
Your marginal rate is the rate applied to the last dollar you earned — the highest bracket you reach. If you're single with $75,000 of taxable income, your marginal rate is 22%. But that doesn't mean you owe 22% of $75,000.
Effective tax rate
Your effective rate is your actual average — your total tax bill divided by your total income. On $75,000 of taxable income (single filer), your effective rate is around 13%, because most of your income was taxed at 10% and 12%.
💡 Example: If you make $80,000 and get a $5,000 raise, only that extra $5,000 gets taxed at your marginal rate. Your existing $80,000 is unaffected. A raise will always increase your take-home pay — you'll never "lose money" by earning more.
How to Legally Reduce Your Federal Income Tax
There are several legitimate strategies to reduce what you owe — all of them involve reducing your taxable income or claiming credits you're entitled to.
1. Contribute to a pre-tax retirement account
Every dollar you put into a traditional 401(k) or Traditional IRA reduces your taxable income by one dollar. If you contribute $6,000 to a 401(k) and you're in the 22% bracket, you save $1,320 in federal taxes. The 2026 contribution limit is $23,000 for 401(k)s and $7,000 for IRAs ($8,000 if 50+).
2. Use a Health Savings Account (HSA)
If you have a high-deductible health plan, HSA contributions are triple tax-advantaged: they reduce your taxable income now, grow tax-free, and can be withdrawn tax-free for qualified medical expenses. The 2026 limit is $4,150 for individuals and $8,300 for families.
3. Claim all eligible deductions
If you itemize, don't miss deductions for mortgage interest, charitable donations, medical expenses, and state taxes (up to $10,000). If you're self-employed, you can deduct business expenses, the self-employment tax deduction, and self-employed health insurance premiums.
4. Claim tax credits you qualify for
Credits reduce your tax bill dollar-for-dollar — they're even better than deductions. Common credits include the Child Tax Credit ($2,000 per qualifying child), the Earned Income Tax Credit for lower-to-moderate income workers, the Child and Dependent Care Credit, and education credits like the American Opportunity Credit (up to $2,500).
5. Time your income and deductions
If you're a freelancer or business owner, you may be able to accelerate deductible expenses into a high-income year or defer income to a lower-income year. Even for W-2 employees, bunching charitable donations into every other year can push you over the itemizing threshold.
⚠️ Important: These strategies are for informational purposes. Tax planning can get complex depending on your situation. If you have significant income, investment gains, or business income, consulting a licensed CPA can often save you far more than the cost of their services.
What This Calculator Doesn't Include
This calculator gives accurate estimates for most common situations, but it's important to know what it doesn't account for:
- State income taxes — every state has different rules. Use our State Income Tax Calculator for that.
- Alternative Minimum Tax (AMT) — affects higher earners with many deductions
- Net Investment Income Tax (NIIT) — 3.8% additional tax on investment income over certain thresholds
- Self-employment tax — use our 1099 Calculator which includes this
- Complex credits — foreign tax credit, energy credits, business credits
- Phase-outs — some deductions and credits reduce at higher income levels
For most W-2 employees with straightforward finances, this calculator provides a very accurate estimate. For complex situations, consult a CPA.
