The United States uses a progressive tax system, meaning higher portions of income are taxed at higher rates. Your income is divided into brackets, and each portion is taxed at its corresponding rate.
| Rate | Single | Married Filing Jointly | Head of Household |
|---|---|---|---|
| 10% | $0 - $11,600 | $0 - $23,200 | $0 - $16,550 |
| 12% | $11,600 - $47,150 | $23,200 - $94,300 | $16,550 - $63,100 |
| 22% | $47,150 - $100,525 | $94,300 - $201,050 | $63,100 - $100,500 |
| 24% | $100,525 - $191,950 | $201,050 - $383,900 | $100,500 - $191,950 |
| 32% | $191,950 - $243,725 | $383,900 - $487,450 | $191,950 - $243,700 |
| 35% | $243,725 - $609,350 | $487,450 - $731,200 | $243,700 - $609,350 |
| 37% | $609,350+ | $731,200+ | $609,350+ |
Example:If you earn $75,000 as a single filer, you're in the 22% bracket (marginal), but your effective rate is only about 13% because lower portions are taxed at 10% and 12%.
Choose between standard deduction or itemize if you have high mortgage interest, state taxes, or charitable donations.
Contribute to 401(k) or traditional IRA to reduce taxable income. Up to $23,000 for 401(k) in 2024 ($30,500 if 50+).
Health Savings Accounts offer triple tax benefits: deductible contributions, tax-free growth, and tax-free withdrawals for medical expenses.
Credits reduce tax dollar-for-dollar. Look for Child Tax Credit, Earned Income Credit, education credits, and energy credits.
Hold investments over 1 year for lower long-term capital gains rates (0%, 15%, or 20% vs ordinary income rates).
If expecting lower income next year, defer bonuses or income. If expecting higher income, accelerate deductions.
No, this calculator only estimates federal income tax. State income tax varies by state (0-13.3%). Some states have no income tax, while others like California have high rates.
Deductions reduce your taxable income (saving you your marginal rate). Credits reduce your tax bill dollar-for-dollar (more valuable). A $1,000 credit saves $1,000 in taxes, while a $1,000 deduction saves $220 if you're in the 22% bracket.
Take the standard deduction unless your itemized deductions (mortgage interest, state taxes, charitable donations, medical expenses) exceed it. For 2024, standard deduction is $13,850 (single), $27,700 (married), $20,800 (head of household).
Maximize retirement contributions (401k, IRA), contribute to HSA, claim all eligible credits and deductions, harvest tax losses, donate to charity, and consider tax-advantaged investments like municipal bonds.
Federal tax returns are due April 15th (or next business day). You can file for an automatic 6-month extension to October 15th, but any tax owed is still due April 15th to avoid penalties and interest.
