Step 1: Calculate Your Federal Income Tax
Federal income tax uses a progressive bracket system. The 2026 brackets for single filers: 10% ($0-$11,925), 12% ($11,926-$48,475), 22% ($48,476-$103,350), 24% ($103,351-$197,300), 32% ($197,301-$250,525), 35% ($250,526-$626,350), 37% (over $626,350).
Step 2: Add FICA Payroll Taxes (7.65%)
FICA funds Social Security (6.2% up to $184,500 wage base) and Medicare (1.45%, no cap). Total: 7.65% of gross wages.
Step 3: Calculate State Income Tax
Eight states have no income tax: Alaska, Florida, Nevada, South Dakota, Tennessee, Texas, Washington, Wyoming. Other states range from 1% (North Dakota) to 13.3% (California).
Step 4: Subtract Pre-Tax Deductions
401(k) up to $24,500, Traditional IRA up to $7,000, HSA up to $4,400 (self). These lower your taxable income.
Step 5: Apply Tax Credits
Child Tax Credit ($2,000/child), EITC (up to $7,430), American Opportunity Credit ($2,500/student), Saver's Credit ($1,000).
Step 6: Calculate Your Total Tax Bill
Total Tax = Federal Income Tax + FICA + State Income Tax - Tax Credits
