How the US Tax System Works

The United States uses a progressive marginal tax system. This means different portions of your income are taxed at different rates — only the income within each bracket is taxed at that bracket's rate.

Common misconception: if you're in the 22% bracket, you don't pay 22% on all your income — only on the portion that falls within the 22% range. Your lower income is still taxed at 10% and 12%.

Standard vs. Itemized Deductions

The standard deduction in 2025 is $15,000 (Single), $30,000 (Married Filing Jointly), and $22,500 (Head of Household). Only itemize if your mortgage interest, charitable contributions, state/local taxes, and medical expenses exceed the standard deduction.

  • State/local income taxes (varies by state)
  • FICA taxes (Social Security: 6.2%, Medicare: 1.45%)
  • Alternative Minimum Tax (AMT)
  • Net Investment Income Tax (3.8% on investment income for high earners)
  • Self-employment tax

FAQs

Deductions reduce your taxable income — worth the deduction × your marginal rate. A $1,000 deduction in the 22% bracket saves $220. Credits directly reduce your tax owed — a $1,000 credit saves $1,000 regardless of your bracket. Credits are almost always more valuable than deductions of the same amount.
In 2025, the Child Tax Credit is $2,000 per qualifying child under age 17. Up to $1,700 is refundable (the Additional Child Tax Credit). The credit begins phasing out at $400,000 of income for MFJ filers and $200,000 for all others.
Yes — traditional 401(k) and IRA contributions directly reduce your taxable income, saving you taxes at your marginal rate. At the 22% bracket, each $1,000 in traditional contributions saves $220 in federal taxes. This is one of the most powerful legal tax reduction tools available to most workers.
Itemize when your eligible deductions (mortgage interest, SALT up to $10k, charitable donations, unreimbursed medical expenses over 7.5% of AGI) exceed the standard deduction. Since the 2017 tax law raised standard deductions significantly, only about 10% of taxpayers now itemize.
