2026 federal income tax brackets

Remember: brackets are marginal — if you're single with $60,000 of taxable income, only the dollars above $50,400 are taxed at 22%. Nobody pays their "bracket" on all their income.

Your marginal rate drives every decisionRoth vs traditional, harvesting gains, bunching deductions — all hinge on your marginal rate (the tax on your next dollar), not your effective rate. Find yours in the table above using taxable income (after the standard/itemized deduction).

Standard deduction vs itemizing

With the 2026 standard deduction at $16,100 single / $32,200 joint, most households don't itemize. Itemize only if the total of these exceeds your standard deduction:

  • State & local taxes (SALT): capped at $40,000 for 2026–2029 under the One Big Beautiful Bill Act ($20,000 if married filing separately). Big relief for high-tax states vs the old $10,000 cap.
  • Mortgage interest: on up to $750,000 of acquisition debt ($375,000 MFS).
  • Charitable donations: cash and non-cash gifts to qualified charities.
  • Medical expenses: only the amount above 7.5% of AGI.

Bunching: if you're near the threshold, stack two years of charitable gifts (via a donor-advised fund) into one year to itemize, then take the standard deduction the next. Alternating years beats itemizing "a little" every year.

Capital gains & dividends

Holding periodRateNotes
Short-term (≤ 1 year)Your ordinary income rateDay-trading profits are taxed like wages — expensive
Long-term (> 1 year)0%, 15%, or 20%Most investors pay 15%; 0% up to ~$48k single / ~$96k joint taxable income; 20% at high incomes
Qualified dividendsSame as long-term ratesMost US-stock dividends qualify

Tax-loss harvesting: in a taxable brokerage, sell losers to offset winners (up to $3,000 of ordinary income per year, rest carries forward). Mind the wash-sale rule — don't rebuy the same security within 30 days. Net investment income tax: an extra 3.8% on investment income above $200k single / $250k joint.

Roth vs traditional: the tax view

  • Traditional 401(k)/IRA: deduction now at your current marginal rate. Best when that rate is high (24%+) and you expect lower income in retirement.
  • Roth: no deduction now; tax-free forever. Best at 10–12% brackets or when you're young with decades of compounding ahead.
  • The tiebreaker most people miss: required minimum distributions. Big traditional balances force taxable withdrawals at 73/75. Roth money has no RMDs and gives you control over your retirement tax bracket. See Retirement.

Credits & deductions worth knowing

  • Child Tax Credit: up to $2,200 per qualifying child under 17 (2026, per OBBBA) — a credit reduces tax dollar-for-dollar, worth far more than a deduction.
  • Saver's Credit: 10–50% credit on retirement contributions for low-to-moderate earners — free money for saving.
  • American Opportunity / Lifetime Learning credits: up to $2,500/yr for college costs (see Kids & College).
  • HSA contributions: deductible "above the line" — they lower AGI even if you don't itemize.
  • Student loan interest: up to $2,500 deductible, phases out at higher incomes.
  • New 65+ bonus deduction: OBBBA added a temporary extra deduction for filers 65 and older (2025–2028) on top of the standard deduction.
  • Electric vehicle / clean energy credits: rules changed significantly under OBBBA — verify current eligibility at IRS.gov before assuming a credit exists.

Self-employed? Read this twice

  • You pay both halves of FICA: 15.3% self-employment tax (12.4% Social Security to $184,500 + 2.9% Medicare) on top of income tax. Budget ~25–35% of profit for taxes.
  • Quarterly estimated taxes are due Jan/Apr/Jun/Sep. Miss them and penalties accrue — set up IRS Direct Pay and automate.
  • Your best deductions: retirement contributions (Solo 401(k) up to $72,000), HSA, health insurance premiums, home-office, and the 20% QBI deduction on qualified business income. Full playbook in Business Owners.

Year-end strategies that work

  1. Fill your bracket: in a low-income year (job change, sabbatical, early retirement), do Roth conversions up to the top of your current bracket — pay 12% now instead of 24%+ later.
  2. Harvest gains at 0%: in the 0% capital-gains zone, sell and rebuy appreciated stock to step up your cost basis tax-free.
  3. Donate appreciated stock instead of cash: deduct the fair market value, never pay the capital-gains tax.
  4. Max pre-tax accounts before Dec 31 (401(k)); you have until April 15 for IRAs and HSAs.
  5. Check withholding with the IRS Tax Withholding Estimator — a big refund means you gave the IRS an interest-free loan.

FAQs

Should I do Roth or traditional 401(k)?

If you're in the 22% bracket or below and under 40, Roth is usually the better bet — decades of tax-free growth. In the 32%+ brackets, traditional usually wins. In between, split the difference. Try the Roth vs traditional calculator.

How do I pay less tax legally?

The big three: max pre-tax retirement accounts, use an HSA if eligible, and harvest investment losses. Beyond that: bunch charitable gifts, time income into low years, and locate assets tax-efficiently (bonds in pre-tax, stocks in Roth). Avoid anyone selling "secret" tax shelters — if it sounds too good, it's fraud.

Do I need to file quarterly taxes?

If you'll owe $1,000+ beyond withholding (typical for freelancers, landlords, business owners), yes — four times a year. The safe harbor: pay 100% of last year's tax (110% if high income) through withholding + estimates and you'll avoid penalties even if you underpay.

What records should I keep?

Keep returns and supporting docs 3 years minimum (7 if you underreported significantly). Keep property/investment purchase records until 3 years after you sell. A simple cloud folder per tax year beats a shoebox.
