A flexible tool to estimate income tax liability. Users can define their own tax brackets (income ranges and corresponding rates), enter their total income, and list any deductions. The calculator then computes the taxable income and applies the user-defined marginal tax rates to each portion of the income, providing a detailed breakdown of the tax owed per bracket and the total estimated tax liability. This is useful for tax planning and understanding the impact of changes in income or deductions. All data is saved in your browser's local storage.
