About Income Tax Calculator

The Income Tax Calculator estimates your federal income tax refund or amount owed based on your income, deductions, credits, and tax withholding. It uses the latest tax brackets and rates for 2024 and 2025 to provide accurate calculations.

How Income Tax is Calculated

The calculator follows these steps to determine your tax liability:

  1. Calculate Total Income: Sum of all income sources including wages, interest, dividends, capital gains, etc.
  2. Calculate Adjusted Gross Income (AGI): Total income minus certain adjustments like IRA contributions.
  3. Apply Deductions: Either the standard deduction or itemized deductions (whichever is higher).
  4. Calculate Taxable Income: AGI minus deductions.
  5. Calculate Federal Income Tax: Based on tax brackets for your filing status.
  6. Calculate Credits: Apply any applicable tax credits to reduce tax liability.
  7. Determine Refund or Amount Owed: Compare tax liability with tax withheld.

Understanding Your Tax Results

Tax Refund: If you've paid more in taxes through withholding than your actual tax liability, you'll receive a refund.

Tax Owed: If you haven't paid enough in taxes through withholding, you'll owe additional taxes when you file.

Adjusted Gross Income (AGI): An important figure that determines eligibility for many tax deductions and credits.

Taxable Income: The amount of income that's actually subject to tax after deductions.
