How this calculation works
- 1. Taxable income โ your gross annual income minus any income exempted under the Sixth Schedule.
- 2. Slab-by-slab tax โ the tax-free threshold is applied first, then each subsequent slab is taxed at its own rate. Only the portion of income inside a slab is taxed at that slab's rate.
- 3. Investment rebate โ deducted as the lowest of the three figures set under Admin โ Tax rates โ Calculation rules.
- 4. Minimum tax โ if your computed tax falls below the minimum for your area, the minimum applies instead.
- 5. Balance โ any tax already deducted at source or paid in advance is subtracted to give what you still owe.
