A flexible tax calculator without hard-coded regional rules
This calculator is designed for planning when you already know the tax rate or effective rate you want to test. It does not pretend to reproduce a specific government return, filing status, deduction schedule or tax year.
Use it to compare gross income, taxable income, estimated tax and take-home income under different assumptions. For an official filing or payroll decision, use the current rules and forms that apply to your jurisdiction.

- Enter annual gross income.
- Subtract deductions or exemptions that reduce the taxable amount.
- Enter the tax rate you want to model.
- Add credits and any separate tax amount.
