Tax Brackets Cheat Sheet

Tax brackets define the rate at which your income is taxed at different levels. The US uses a progressive system — you don’t pay the highest rate on all your income, only on the portion that falls within each bracket. Understanding marginal vs. effective tax rates is essential for financial planning.

Marginal vs. Effective Tax Rate

Effective Tax Rate Total Tax Paid ÷ Total Taxable Income × 100

Your marginal rate is the tax on your last dollar earned. Your effective rate is your average rate across all income. A single filer earning $100,000 in 2025 has a 22% marginal rate but an effective rate of roughly 17%.

Net Investment Income Tax (NIIT)

High earners pay an additional 3.8% surtax on investment income (dividends, capital gains, interest, rental income) above these thresholds:

Filing StatusMAGI Threshold
Single$200,000
Married Filing Jointly$250,000
Married Filing Separately$125,000
Analyst Tip
Tax-loss harvesting lets you offset capital gains by selling losing investments. You can deduct up to $3,000 in net losses against ordinary income per year, with unused losses carrying forward indefinitely. This is one of the most effective tax strategies for investors.
Watch Out
Tax brackets change annually with inflation adjustments. The rates above are for 2025. Many provisions of the 2017 Tax Cuts and Jobs Act are scheduled to sunset after 2025, which could significantly change brackets and deductions. Always verify current rates with the IRS.

Key Takeaways

  • The US uses a progressive tax system — only income within each bracket is taxed at that rate
  • Long-term capital gains are taxed at preferential rates (0%, 15%, or 20%)
  • Your effective tax rate is always lower than your marginal rate
  • The standard deduction reduces taxable income before brackets apply
  • Tax brackets adjust annually for inflation — always check current year figures

Frequently Asked Questions

What is the difference between marginal and effective tax rate?

Your marginal tax rate is the rate on your last dollar of income — it’s your highest bracket. Your effective rate is the average rate across all your income. Everyone’s effective rate is lower than their marginal rate because of the progressive system.

How do tax brackets work with investment income?

Short-term capital gains and ordinary dividends are added to your regular income and taxed at ordinary rates. Long-term capital gains and qualified dividends have their own preferential rate schedule (0%, 15%, or 20%).

Does a higher tax bracket mean all my income is taxed at that rate?

No. This is the most common tax misconception. Only the income within each bracket is taxed at that rate. If you move from the 22% to the 24% bracket, only the dollars above the 22% threshold are taxed at 24%.

What is the 3.8% net investment income tax?

The NIIT is a surtax on investment income for high earners. It applies to the lesser of your net investment income or the amount your MAGI exceeds the threshold ($200k single, $250k married). It effectively adds 3.8% to the capital gains rate for high-income investors.

How can I reduce my taxable income?

Maximize 401(k) and Traditional IRA contributions, use HSA contributions, apply tax-loss harvesting, hold investments for over 1 year for long-term rates, and consider charitable giving strategies. Each strategy reduces taxable income at your marginal rate.
