Frequently Asked Questions
What are the 2025 federal income tax brackets?
For 2025 (filing in 2026), the IRS has 7 tax brackets: 10%, 12%, 22%, 24%, 32%, 35%, and 37%. For single filers: 10% up to $11,925; 12% on $11,926–$48,475; 22% on $48,476–$103,350; 24% on $103,351–$197,300; 32% on $197,301–$250,525; 35% on $250,526–$626,350; 37% above $626,350. Married filing jointly brackets are approximately double these thresholds. These are 2025 amounts per IRS Revenue Procedure 2024-40.
What is the difference between marginal and effective tax rate?
Your marginal tax rate is the rate on your last dollar of income — the highest bracket you fall into. Your effective tax rate is your total tax divided by total income — the average rate you actually pay. Because the US has a progressive tax system, you only pay each rate on the income within that bracket. Example: $100,000 income (single, 2025) — taxable income after $15,000 standard deduction is $85,000. Tax ≈ $15,100; effective rate ≈ 15.1%; marginal rate = 22%.
What is the 2025 standard deduction?
The 2025 standard deduction (per IRS Rev. Proc. 2024-40): Single or Married Filing Separately = $15,000; Married Filing Jointly = $30,000; Head of Household = $22,500. These are $400 higher than 2024 amounts due to inflation adjustments. The standard deduction reduces your taxable income — most taxpayers claim it rather than itemizing. You should itemize only if your deductible expenses (mortgage interest, state/local taxes, charitable donations, etc.) exceed the standard deduction.
How do I reduce my federal income taxes?
Legal tax reduction strategies include: (1) Maximize pre-tax 401k/403b contributions ($23,500 limit in 2025; $31,000 if age 50+) — directly reduces taxable income. (2) Contribute to an HSA ($4,300 single / $8,550 family in 2025) — triple tax advantage. (3) Harvest tax losses in taxable investment accounts. (4) Claim all eligible deductions and credits (Child Tax Credit $2,000/child, Education Credits, Saver's Credit). (5) Consider a traditional IRA if eligible for deduction ($7,000 limit in 2025).
What taxes are not included in this calculator?

Your total tax burden is typically 25–40% when all taxes are considered.
