Part 1: India Income Tax Slabs & Calculation (FY 2026-27)
In India, taxpayers choose between the New Tax Regime (default) and the Old Tax Regime (which offers various deductions under Section 80C, 80D, and HRA).
1. New Tax Regime Slabs (FY 2026-27 / AY 2027-28)
Under the updated framework, the concessional tax slabs are structured as follows:
| Taxable Income Slab (INR) | Tax Rate |
|---|---|
| Up to ₹3,00,000 | Nil (0%) |
| ₹3,00,001 to ₹7,00,000 | 5% |
| ₹7,00,001 to ₹10,00,000 | 10% |
| ₹10,00,001 to ₹12,00,000 | 15% |
| ₹12,00,001 to ₹15,00,000 | 20% |
| Above ₹15,00,000 | 30% |
(Note: Standard Deduction is applicable for salaried individuals, and tax rebates under Section 87A help eliminate tax liability up to specified threshold limits).
2. Step-by-Step Income Tax Calculation Example in India
Let us assume an individual has an annual taxable income of ₹12,00,000 under the New Tax Regime:
- Up to ₹3,00,000: ₹0
- ₹3,00,001 to ₹7,00,000 (₹4,00,000 @ 5%): ₹20,000
- ₹7,00,001 to ₹10,00,000 (₹3,00,000 @ 10%): ₹30,000
- ₹10,00,001 to ₹12,00,000 (₹2,00,000 @ 15%): ₹30,000
- Total Tax Liability: ₹20,000 + ₹30,000 + ₹30,000 = ₹80,000 (plus applicable health and education cess).

Frequently Asked Questions (People Also Ask)

Q2. How do marginal tax brackets work in the United States?
Ans: In the US progressive tax system, your entire income is not taxed at a single rate. Instead, different portions of your income are taxed at increasing marginal rates as your income crosses specific bracket thresholds.
