Frequently Asked Questions
What are the 2026 federal income tax brackets?
The IRS 2026 tax brackets (adjusted for inflation per Rev. Proc. 2025-28) for single filers are: 10% up to $11,925 · 12% $11,926–$48,475 · 22% $48,476–$103,350 · 24% $103,351–$197,300 · 32% $197,301–$250,525 · 35% $250,526–$626,350 · 37% above $626,350. Brackets differ for married filing jointly and head of household.
What is the standard deduction for 2026?
The 2026 standard deduction is $15,000 for single filers and married filing separately, $30,000 for married filing jointly, and $22,500 for head of household. These are increased from 2025 due to inflation adjustments.
What is the difference between marginal and effective tax rate?
Your marginal tax rate is the rate applied to your last dollar of income — your highest bracket. Your effective tax rate is your total federal tax divided by your gross income. Because the US uses a progressive system, only the portion of income in each bracket is taxed at that rate, so your effective rate is always lower than your marginal rate.
Is this calculator accurate for my actual tax return?
This calculator provides an estimate based on standard IRS brackets and a simplified model. It does not account for credits (Child Tax Credit, Earned Income Credit, etc.), the Alternative Minimum Tax (AMT), self-employment tax, investment income, or specific deductions. For your actual return, consult a CPA or enrolled agent.
How is state income tax calculated here?
State tax is estimated using a simplified flat rate approximation for each state. Actual state taxes use graduated brackets, various deductions, and credits specific to each state. This estimate is for comparison purposes only.
