Tax Calculator FAQ
Our tax calculators use current 2025 federal tax brackets, FICA rates, and standard deductions for maximum accuracy. Results are estimates and may vary based on specific circumstances, deductions, or credits. Always consult a tax professional for complex situations.
Your marginal tax rate is the percentage you pay on your last dollar of income (highest tax bracket). Your effective tax rate is your total tax divided by total income - typically much lower than your marginal rate due to progressive tax brackets.
Aim to have enough withheld to owe less than $1,000 at tax time or pay at least 90% of current year's tax (100% if prior year AGI > $150,000). Use our withholding calculator to find the right amount for your situation.
Yes, if you expect to owe $1,000 or more in taxes, you should make quarterly estimated tax payments. This includes both income tax and self-employment tax (15.3% for Social Security and Medicare). Use our contractor tax calculator to estimate payments.
Bonuses are supplemental income and may be withheld at a flat 22% federal rate (or your marginal rate if over $1 million). However, they're taxed at your regular income tax rate when you file your return. The withholding is just an estimate.
The additional Medicare tax is 0.9% on income over $200,000 (single) or $250,000 (married filing jointly). This is paid only by the employee, not matched by the employer. It applies to wages, self-employment income, and railroad retirement compensation.
