New Tax Regime Slabs FY 2026-27

The new tax regime is the default for FY 2026-27. It has lower slab rates but allows fewer deductions -- only the Rs. 75,000 standard deduction applies automatically.

Up to Rs. 4 Lakh0%Nil
Rs. 4L to Rs. 8L5%Up to Rs. 20,000

Section 87A rebate eliminates tax entirely for taxable incomes up to Rs. 12 Lakh. After adding the Rs. 75,000 standard deduction, this means zero tax up to a gross income of Rs. 12.75 Lakh.

Old Tax Regime Slabs FY 2026-27

The old regime allows deductions under 80C, 80D, HRA, home loan interest, and NPS. It is better when your total deductions are large enough to reduce taxable income significantly.

Frequently Asked Questions

Under the new regime, Rs. 10L gross minus Rs. 75,000 standard deduction gives Rs. 9.25L taxable. The tax on Rs. 9.25L works out to Rs. 42,500 -- but since taxable income is below Rs. 12L, the 87A rebate eliminates it entirely. Zero tax.
Yes. Rs. 75,000 standard deduction brings Rs. 12.75L gross down to exactly Rs. 12L taxable income. Section 87A rebate then eliminates 100% of the tax liability. You pay zero income tax.
Cess is charged on the income tax amount -- not on your income. If your income tax is Rs. 50,000, cess adds Rs. 2,000 (4%), making total tax Rs. 52,000. If 87A rebate makes your tax zero, cess is also zero.
Salaried employees can switch regime every financial year. You declare your choice to your employer at the start of the year for TDS purposes, but can revise when filing your ITR. Business owners face more restrictions on switching.
The new regime allows very few deductions: the Rs. 75,000 standard deduction, employer NPS contribution (80CCD(2)), and a few others. It does not allow 80C, 80D, HRA exemption, home loan interest, or most common investments.
