How to use this calculator
Enter your total annual income and the deductions or allowances you can claim, then press Calculate. The calculator deducts them from your income first, then applies the tax slabs to the remaining amount.
Formula
The tax is worked out in steps: only the part of your taxable income inside each band is taxed at that band’s rate. Above $80,000, only the part above $80,000 pays 30% — the first $80,000 pays less.
| Taxable income | Rate |
|---|---|
| First $10,000 | 0% |
| $10,001 – $40,000 | 10% |
| $40,001 – $80,000 | 20% |
| Above $80,000 | 30% |
Frequently asked questions
What is taxable income?
Taxable income is your total income minus the deductions and allowances you can claim. Only this amount is used to work out your tax — not your full income.
What is the difference between a tax slab and the effective rate?
A slab is the rate that applies to one band of income. The effective rate is the average rate you pay overall (total tax ÷ total income), which is usually lower than your top slab.
Can I rely on this result for my tax return?
No. Rates and rules differ by country and change over time. This calculator is a learning tool only — check your local tax authority or a qualified tax adviser for your real tax bill.
