How US Federal Income Tax Works in 2026
The United States uses a progressive tax system — meaning you do not pay a flat rate on all your income. Instead, your income is divided into portions called tax brackets, and each portion is taxed at a different rate. Higher portions of income are taxed at higher rates, but crucially, only the income in that bracket is taxed at that rate.
2026 Federal Income Tax Brackets
The IRS updates tax brackets each year for inflation. Below are the official 2026 federal tax brackets for each filing status.

2026 Standard Deductions
Before calculating your tax, the IRS lets you reduce your taxable income by the standard deduction. For 2026 these are:
- Single: $15,000
- Married Filing Jointly: $30,000
- Head of Household: $22,500
- Married Filing Separately: $15,000
FICA Taxes: Social Security and Medicare
In addition to federal income tax, most employees pay FICA taxes which fund Social Security and Medicare. For 2026:
- Social Security: 6.2% on wages up to $176,100 (the wage base limit)
- Medicare: 1.45% on all wages, no income limit
- Additional Medicare tax: 0.9% on wages above $200,000 (single) or $250,000 (married filing jointly)
Your employer matches your Social Security and Medicare contributions — so the full FICA cost to your employer is 15.3%. As an employee, you pay 7.65%. If you are self-employed, you pay both sides (15.3%), but you can deduct half as a business expense.
State Income Tax Overview
On top of federal tax, most states charge their own income tax. State tax rates vary widely — from 0% in states like Texas, Florida, and Nevada to over 13% in California for the highest earners.
How to Reduce Your Tax Bill Legally
There are several legitimate ways to reduce the amount of income tax you owe in 2026:
- Contribute to a 401(k) or 403(b): Contributions reduce your taxable income dollar-for-dollar, up to $23,500 in 2026 ($31,000 if you are 50 or older).
- Contribute to a Traditional IRA: Up to $7,000 per year ($8,000 if 50+) may be deductible depending on your income and whether you have a workplace retirement plan.
- Use an HSA: If you have a high-deductible health plan, HSA contributions are tax-deductible up to $4,300 (individual) or $8,550 (family) in 2026.
- Claim all eligible deductions: Business expenses, student loan interest, and educator expenses can reduce your taxable income.
- Tax credits over deductions: Credits like the Child Tax Credit ($2,000 per child) reduce your tax owed dollar-for-dollar, which is more valuable than deductions.
