Tax Slabs for AY 2026-27 You Should Know
The tax slabs for AY 2026-27 are taken from the latest tax rules applicable to income earned in FY 2025-26. Here’s how they generally look under the new tax regime:
New Tax Regime (Section 115BAC) – AY 2026-27
| Taxable Income | Tax Rate |
|---|---|
| Up to ₹4,00,000 | 0% |
| ₹4,00,001 – ₹8,00,000 | 5% |
| ₹8,00,001 – ₹12,00,000 | 10% |
| ₹12,00,001 – ₹16,00,000 | 15% |
| ₹16,00,001 – ₹20,00,000 | 20% |
| ₹20,00,001 – ₹24,00,000 | 25% |
| Above ₹24,00,000 | 30% |
These slabs apply regardless of age under the new regime. The old tax regime uses different slabs and allows more deductions, especially useful for those with higher investments or exemptions.
Standard Deduction & Section 87A Rebate – Important Calculator Inputs
Two key benefits factored in by the Income Tax Calculator for AY 2026-27 are:
Standard Deduction
Salaried individuals and pensioners enjoy a standard deduction (usually ₹75,000) from their gross salary before tax is calculated. This directly reduces taxable income.
Section 87A Rebate
Under the new regime, taxpayers with taxable income up to ₹12,00,000 can claim a rebate that can reduce tax to zero in many cases, especially after standard deduction adjustments.
These features are automatically calculated when you use the online tax calculator.
