Income Tax Calculator

Estimate your income tax, net income, and effective tax rate using your gross income, deductions, and tax rates.

Your Details

Overview

This income tax calculator helps you estimate taxable income, total tax, net income, and your effective tax rate using your annual income, pre-tax deductions, tax-free allowance, and tax rates. It is designed for simple planning when you want a quick estimate rather than a full tax return calculation.

How it works

The calculator first subtracts pre-tax deductions from your annual income to estimate adjusted income. It then subtracts any tax-free allowance to find taxable income. Your entered tax rates are applied to that taxable income to estimate income tax and any additional taxes. Total tax is then subtracted, along with pre-tax deductions, from gross income to estimate net income. The effective tax rate shows total tax as a percentage of gross income.

How to use this calculator

  1. 1Enter your annual gross income before tax.
  2. 2Add any pre-tax deductions that reduce taxable income.
  3. 3Enter your tax-free allowance or personal allowance.
  4. 4Input your estimated income tax rate and any additional tax rate.
  5. 5Review your estimated taxable income, total tax, net income, and effective tax rate.

Pre-tax deductions are amounts taken from income before tax is calculated, such as some retirement contributions or eligible benefit deductions.

What is a tax-free allowance?

A tax-free allowance is the portion of income that is not taxed, if applicable in your location or situation.
