How progressive taxation works
The United States uses a progressive tax system. Instead of taxing your entire income at a single rate, the IRS slices your taxable income into layers and taxes each layer at the rate assigned to its bracket. Only the dollars that actually fall inside a bracket are taxed at that bracket's rate. Because of this, earning more money and "moving into a higher bracket" never causes you to owe more tax on the income below it — a common misconception. Your lower-bracket dollars keep their lower rates.
Here is a concrete example using 2025 single-filer brackets. Say your taxable income is $60,000 (after deductions). The first $11,925 is taxed at 10%, the next $36,550 (from $11,925 to $48,475) at 12%, and only the final $11,525 (from $48,475 to $60,000) at 22%:
12% × $36,550 = $4,386.00
22% × $11,525 = $2,535.50
───────────────────────────
Total federal tax = $8,114.00
Notice that none of the $60,000 is taxed at a flat 22%. The blended result is far lower — that blend is your effective rate.
Marginal vs. effective tax rate
These two terms get confused constantly, but they measure different things:
- Marginal tax rate is the rate on your last dollar of taxable income — the top bracket you reach. It answers "if I earn one more dollar, how much of it goes to federal tax?" For our $60,000 example that is 22%, because the final dollar lands in the 22% bracket.
- Effective tax rate is your total tax divided by your total (gross) income — the average rate you actually pay overall. For $60,000 of taxable income with $8,114 of tax against $75,000 of gross income, the effective rate is about 10.8%.
Your effective rate is almost always meaningfully lower than your marginal rate. Marginal rate matters for decisions like "should I work extra hours or contribute more to a 401(k)?", while effective rate describes your overall tax burden.

About FICA payroll taxes
FICA is separate from income tax and funds Social Security and Medicare. It is withheld from every paycheck regardless of how many allowances you claim. For 2025, Social Security takes 6.2% of your wages up to a $176,100 wage base (income above that cap is not subject to the 6.2%), while Medicare takes 1.45% of all wages with no cap. Together that is 7.65% of most workers' pay. Self-employed people pay both the employee and employer halves (SECA), but this calculator models the employee side. Importantly, pre-tax 401(k) contributions lower your income tax but not your FICA tax.
Tips to reduce your taxable income
- Max out pre-tax retirement accounts. Traditional 401(k), 403(b), and traditional IRA contributions are deducted from taxable income. The 2025 401(k) elective deferral limit is $23,500 (with a $7,500 catch-up if you're 50+). Model it with the 401(k) field above.
- Use a Health Savings Account (HSA). HSA contributions are pre-tax, grow tax-free, and are tax-free for qualified medical expenses. For 2025 you can contribute up to $4,300 (self) or $8,550 (family).
- Fund a Flexible Spending Account (FSA). A dependent-care or health FSA uses pre-tax dollars for predictable expenses, lowering adjusted gross income.
- Claim above-the-line adjustments. Educator expenses, student-loan interest, and half of self-employment tax reduce income even if you take the standard deduction.
- Harvest investment losses. Selling losing investments to offset gains (up to $3,000 of ordinary income per year) trims taxable income.
- Pick the right deduction. Compare standard vs. itemized each year — the calculator's "Custom" deduction mode lets you test an itemized total against the standard amount.
