Frequently Asked Questions
What is the difference between effective and marginal tax rate?
Your marginal tax rate is the rate applied to your last dollar of income — the top bracket you fall into. Your effective tax rate is the average rate you pay across all your income. For example, a $80,000 single filer has a 22% marginal rate but an effective rate of around 13%, because the first portions of income are taxed at 10% and 12%.
What are the 2025 federal tax brackets?
For single filers in 2025: 10% on income up to $11,925; 12% up to $48,475; 22% up to $103,350; 24% up to $197,300; 32% up to $250,525; 35% up to $626,350; 37% above that. Married filing jointly thresholds are approximately double.
What is the standard deduction for 2025?
The 2025 standard deduction is $15,000 for single filers and $30,000 for married filing jointly. This calculator uses gross income without deductions applied — subtract your standard deduction from your income before entering it for a more accurate estimate.
Does this calculator include state income tax?
No — this calculator estimates US federal income tax only. State income tax rates vary widely: some states like Florida and Texas have no income tax, while California's top rate reaches 13.3%. Add your state rate separately for a complete picture.
What is FICA tax and is it included?
FICA (Federal Insurance Contributions Act) taxes include Social Security (6.2% up to $176,100 in 2025) and Medicare (1.45%, plus 0.9% above $200,000). This calculator covers federal income tax only and does not include FICA. Your total payroll tax burden will be higher.
How can I reduce my federal income tax?
Common strategies include maximizing 401(k) or IRA contributions (which reduce taxable income), contributing to an HSA, claiming eligible deductions and credits, and timing income or deductions across tax years. Consult a tax professional for personalized advice.
