Comment Fonctionne le Calcul
Calcul d'impôt sur le revenu suit procédures IRS : D'abord, calculez revenu brut ajusté (AGI) à partir du revenu brut. Puis soustrayez déduction standard ou déductions détaillées, plus exemptions personnelles par personnes à charge. Le revenu imposable résultant est taxé en utilisant catégories progressives où chaque portion de revenu est taxée à différents taux. L'impôt étatique sur le revenu est calculé séparément en utilisant taux spécifiques de l'état. Les crédits fiscaux sont soustraits directement de la responsabilité fiscale totale. Le taux effectif d'impôt est impôt total divisé par revenu brut, tandis que le taux marginal est le taux appliqué au dernier euro gagné.

Frequently Asked Questions
What's the difference between marginal tax rate and effective tax rate?
Your marginal tax rate is the tax rate applied to your last dollar of income - the highest tax bracket you fall into. Your effective tax rate is your total tax liability divided by your total income - the average rate you pay on all your income. Most taxpayers have an effective rate lower than their marginal rate.
What is taxable income?
Taxable income is your adjusted gross income (AGI) minus deductions and exemptions. AGI includes wages, salaries, tips, and other income sources minus certain adjustments. Deductions can be the standard amount or itemized expenses like mortgage interest, state taxes paid, and charitable donations. Exemptions are amounts subtracted for each dependent and yourself.
What tax credits are available?
Common tax credits include the Child Tax Credit (up to $2,000 per qualifying child), Child and Dependent Care Credit, Education Credits (American Opportunity and Lifetime Learning), Adoption Credit, Electric Vehicle Credit, and energy efficiency credits. Credits reduce your tax liability dollar-for-dollar, unlike deductions which reduce your taxable income.
How do I choose between standard and itemized deductions?
Compare the standard deduction amount to your itemized deductions total. Use whichever gives you the greater deduction. The standard deduction is simpler but itemizing can be beneficial if you have significant mortgage interest, state taxes paid, charitable donations, or medical expenses exceeding 7.5% of AGI. Most taxpayers use the standard deduction.
Why do states have different tax rates?
Nine states have no state income tax (Texas, Florida, Nevada, Washington, Wyoming, South Dakota, Alaska, Tennessee, New Hampshire). Other states have progressive tax systems with rates typically ranging from 3% to 13.3%, depending on income level and state-specific tax structures. Some states also tax different types of income differently.
What income is subject to federal income tax?
Almost all income is subject to federal income tax including wages, salaries, tips, bonuses, self-employment income, interest, dividends, capital gains, rental income, and retirement distributions. Some income may be tax-exempt such as certain Social Security benefits, municipal bond interest, and gifts under $19,000 annually (2026 limit).
How often do tax brackets change?
Tax brackets are indexed for inflation and typically adjusted annually. Major tax law changes can also affect brackets, deductions, and credits. Tax rates and deductions are regularly updated to reflect current tax law and inflation adjustments.
