How US federal income tax works
The US uses a progressive tax system — higher income is taxed at higher rates, but only the portion that falls within each bracket. If you're in the 22% bracket, you don't pay 22% on all your income; you pay 10% on the first slice, 12% on the next, and 22% only on the income above the 12% threshold.
Before tax is calculated, your income is reduced by a deduction. The 2026 standard deduction for single filers is $16,100. Additional deductions and credits may apply but are not included in this estimate. If you have large itemized deductions (mortgage interest, state taxes, charitable donations), you can use those instead if they exceed the standard deduction.
The result is your taxable income. Apply the brackets to this amount to get your marginal tax. Divide total tax by gross income to get your effective rate — always lower than your marginal rate.
Ways to reduce your tax bill
401(k) / IRA contributions
Pre-tax contributions reduce your taxable income dollar-for-dollar. $20,000 in a traditional 401(k) at 22% saves $4,400 in tax.
Health Savings Account (HSA)
Triple tax advantage: contributions reduce income, growth is tax-free, withdrawals for medical expenses are tax-free.
Itemize deductions
Mortgage interest, state and local taxes (up to $10,000), and charitable donations can exceed the standard deduction for many homeowners.
Tax credits
Credits reduce tax directly (not just income). Child tax credit, earned income credit, and education credits can significantly lower your bill.
