For example, California has a progressive tax system with rates from 1% to 13.3%, while Texas has no state income tax.
Payroll Taxes
Payroll taxes include Social Security and Medicare contributions. The rates are:
- Social Security: 6.2% (employee) + 6.2% (employer)
- Medicare: 1.45% (employee) + 1.45% (employer)
Payroll Tax Calculation
Total payroll tax = (Gross Income × 14.1%) × 2 (for employee and employer)
Tax Deductions
Deductions reduce your taxable income. Common deductions include:
- Standard deduction
- Itemized deductions (mortgage interest, charitable contributions, etc.)
- Retirement contributions (401k, IRA)
- Student loan interest
The calculator applies these deductions to your taxable income before calculating federal and state taxes.
Tax Credits
Tax credits directly reduce your tax liability dollar-for-dollar. Common credits include:

- Earned Income Tax Credit (EITC)
- American Opportunity Credit (for education)

Credits can significantly lower your tax bill beyond what deductions provide.
