2026 Federal Income Tax Brackets: Complete Reference

The US income tax is progressive: income is taxed in layers, each at its own rate. For 2026, single filers pay 10% on taxable income up to $12,400, 12% up to $50,400, 22% up to $105,700, 24% up to $201,775, 32% up to $256,225, 35% up to $640,600 and 37% above that. Married couples filing jointly get roughly double the width of each bracket, and heads of household fall between the two. Only the income inside each layer is taxed at that layer's rate, so a raise never pushes lower dollars into a higher bracket. The income tax calculator applies these brackets to your exact filing status, deductions and income.

Effective Tax Rate vs Marginal Tax Rate: The Key Difference

Your marginal rate is the rate on your last dollar of income, set by your highest bracket. Your effective rate is total tax divided by total income, and it is always lower. A single filer with $60,400 taxable income sits in the 22% bracket but pays about 11% of their total income in federal tax. The distinction drives decisions: use the marginal rate to estimate the tax on a raise or side income, and the effective rate to describe your overall burden. The tax bracket calculator reports both automatically.

Standard vs Itemized Deductions for 2026

You deduct whichever is larger: the standard amount or your itemized deductions, which include mortgage interest, state and local taxes generally capped at $40,400 in 2026, subject to separate-return and high-income limits, charitable gifts and medical expenses above 7.5% of income. Since the standard deduction was roughly doubled, most filers no longer benefit from itemizing.

Legal Ways to Reduce Your Tax Bill in 2026

The most powerful levers are pre-tax contributions: a 401(k) up to $24,500 and an HSA up to $4,400 both reduce taxable income today. A traditional IRA adds another $7,500 for eligible filers. Credits beat deductions dollar-for-dollar, so claim every credit you qualify for, including the Child Tax Credit and education credits. Tax loss harvesting can offset up to $3,000 of ordinary income per year. Timing matters too: shifting deductible expenses into the year where they push you below a bracket threshold can save real money.

FICA Taxes: Social Security and Medicare in 2026

FICA is the payroll tax that funds Social Security and Medicare. Employees pay 6.2% for Social Security on wages up to a 2026 wage base of about $184,500, plus 1.45% for Medicare with no cap. High earners pay an additional 0.9% Medicare surtax on income above $200,000 single or $250,000 married filing jointly. Self-employed workers pay both halves, 15.3% total, but can deduct the employer half. Unlike income tax, FICA is flat, which is why lower earners feel payroll taxes more heavily relative to income.
