2026 Federal Tax Brackets
The U.S. uses a progressive tax system with seven brackets. Your marginal tax rate is the rate on your last dollar of income — not your entire income. A single filer earning $50,000 pays 10% on the first $11,600, 12% on $11,601-$47,150, and 22% on $47,151-$50,000 — an effective rate of about 13.5%. Our Take-Home Pay Calculator computes your exact effective rate.
Married filing jointly doubles most bracket thresholds. Our Salary Calculator shows your take-home pay after all federal and state deductions.
Standard vs Itemized: The $30,000 Question
The 2026 standard deduction is $15,000 (single) or $30,000 (married). About 88% of taxpayers use the standard deduction. You should itemize only if your deductible expenses exceed these amounts.
Common itemizable expenses: mortgage interest, state/local taxes (capped at $10,000), charitable donations, and medical expenses exceeding 7.5% of AGI. Our Standard vs Itemized Calculator tells you which saves more in 30 seconds.
Retirement Account Tax Strategies
Retirement contributions are the single most powerful tax reduction tool available:
401(k): Every dollar contributed reduces taxable income. Contributing $23,500 at a 22% bracket saves $5,170 in federal taxes alone. Our 401(k) Calculator models the tax benefit.
Traditional IRA: Up to $7,000 deductible ($8,000 if 50+), income limits apply if covered by a workplace plan.
HSA: If you have an HDHP, contribute $4,300 (individual) or $8,550 (family) for a triple tax benefit. Our HSA Guide explains why it is the most tax-efficient account type.
Capital Gains: Timing Is Everything
Long-term capital gains (assets held 1+ year) are taxed at 0%, 15%, or 20% depending on income — significantly lower than ordinary income rates. Short-term gains (under 1 year) are taxed as ordinary income at rates up to 37%.
Strategy: hold investments at least one year before selling. In low-income years (career transition, early retirement), harvest gains at the 0% rate. Our Capital Gains Calculator shows your tax liability.
Tax Credits vs Deductions
Credits are more valuable than deductions: a $1,000 credit reduces your tax by $1,000 directly, while a $1,000 deduction reduces your tax by $220-$370 (your marginal rate × $1,000). Key 2026 credits: Child Tax Credit ($2,000/child), Earned Income Credit (up to $7,830 for 3+ children), American Opportunity Credit ($2,500 for college), Saver's Credit (up to $2,000 for retirement contributions).
Self-Employment and Side Hustle Taxes
If you earn $400+ from self-employment, you owe self-employment tax (15.3%) in addition to income tax. But you can deduct: home office, mileage (67¢/mile in 2026), equipment, software, phone costs, and health insurance premiums. Our Self-Employment Tax Calculator computes your liability, and our Gig Worker Deductions Guide lists everything you can write off.
