How Tax Calculations Work
Income tax calculations involve several steps: determining your adjusted gross income (AGI), applying deductions to find taxable income, calculating tax using progressive tax brackets, and then adding state and local taxes. This calculator provides a simplified estimation based on general tax principles.
The U.S. tax system is progressive, meaning higher income levels are taxed at higher rates. However, you only pay the higher rate on income above each bracket threshold, not on your entire income. This is often misunderstood but crucial for tax planning.
Tax Calculation Method
Step-by-Step Process
- Gross Income: All income from wages, investments, etc.
- Adjusted Gross Income (AGI): Gross income minus pre-tax contributions
- Deductions: Subtract standard or itemized deductions
- Taxable Income: AGI minus deductions
- Federal Tax: Apply progressive tax brackets
- State Tax: Apply state tax rate (varies by state)
- Total Tax: Federal + State + FICA taxes
