Income Tax Slabs FY 2025‑26: The Basics
The income tax slab system ensures that individuals with higher incomes pay a proportionately higher percentage of tax, while those with lower incomes pay less or none at all. For FY 2025-26 (AY 2026-27), the Union Budget 2025 introduced significant revisions to slab rates under the new tax regime (Section 115BAC).
Good news: Income up to Rs. 12 lakh is now effectively tax-free due to a massive rebate benefit![4][7][10].
What is a ‘slab’ in income tax?
- It’s a range of income with a specific tax rate.
- Your total taxable income determines which slabs/rates apply to you.
- The system is progressive: higher slabs mean higher tax rates, only on the portion in that range.

Real Indian Examples: Tax Calculation for Salaried, Entrepreneur, and Senior Citizen
Example 1: Salaried Employee (Aarav, Mumbai)
- Total annual salary: ₹10,00,000
- No investment deductions under new regime
- Tax as per slabs:
- First ₹4,00,000: Nil
- Next ₹4,00,000 (₹4,00,001–₹8,00,000): 5% = ₹20,000
- Remaining ₹2,00,000 (₹8,00,001–₹10,00,000): 10% = ₹20,000
- Total tax before rebate: ₹40,000
- Taxable income < ₹12L, so sec 87A rebate covers entire tax. Final tax liability: ZERO
Example 2: Startup Founder (Pooja, Bengaluru)
- Total business income: ₹17,50,000
- Tax calculation:
- First ₹4,00,000: Nil
- Next ₹4,00,000: 5% = ₹20,000
- Next ₹4,00,000: 10% = ₹40,000
- Next ₹4,00,000: 15% = ₹60,000
- Remaining ₹1,50,000: 20% = ₹30,000
- Subtotal = ₹1,50,000
- Section 87A rebate not available (>₹12L). Add 4% cess = ₹6,000
- Total tax: ₹1,56,000
Example 3: Senior Citizen (Mrs. Verma, Lucknow)
- Total pension + interest: ₹6,50,000
- First ₹4,00,000: Nil
- Next ₹2,50,000: 5% = ₹12,500
- Section 87A rebate: ₹12,500
- Final tax: ZERO
Note: For retirees, disability, or super senior status may grant further exemptions.
Section 87A Rebate: Why Rs. 12 Lakh Is the New Magic Number
