What are the Two Regimes?

🏛️ Old Regime

The traditional structure where you claim deductions (80C, HRA, Medical). Tax slabs depend on age (Senior citizens get higher exemption).

🆕 New Regime

Introduced to simplify taxes. Offers lower slab rates but removes most deductions. It is now the default option.

Key Updates for AY 2026-27 (FY 2025-26)

New Slabs: Income up to ₹ 4,00,000 is exempt.
Rebate Limit (Sec 87A): Tax liability drops to zero if net taxable income is ≤ ₹ 12,00,000.
Standard Deduction: Increased to ₹ 75,000 for salaried/pensioners under the New Regime.

Side-by-Side Comparison

Feature	Old Regime	New Regime (115BAC)
Exemption Limit	₹ 2.5L - ₹ 5L (Age based)	₹ 4,00,000 (Flat)
Tax Rates	Higher rates in certain bands	Lower rates, smoother progression
Deductions	Allowed (80C, HRA, 80D)	Removed (Except Std Deduction)
87A Rebate Limit	Lower limit	Up to ₹ 12 Lakh Income
Complexity	High (Documentation needed)	Low (Simple filing)

Who Likely Benefits?

👨‍💼

Salaried with few investments

If you don't have a home loan or big 80C investments.

Likely New Regime

🏠

High Deductions (Home Loan + HRA)

If you claim substantial HRA, Home Loan Interest, and Medical Insurance.

Likely Old Regime

👴

Senior Citizens

Mixed bag. Old regime offers higher initial exemption, but New regime is simpler to file.

Check Both

Example Scenarios

Example 1: Income ₹ 10,00,000

Deductions: ₹ 1.5L (80C) + ₹ 60k (HRA) = ₹ 2.1L total.

Verdict: The New Regime usually wins here because the rebate covers income up to ₹ 12L, reducing tax to zero (or near zero), whereas Old Regime would still attract tax on the remaining balance.

Example 2: Income ₹ 25,00,000

Deductions: ₹ 4.5L (Home Loan, 80C, 80D, HRA).

Verdict: The Old Regime is likely better. The massive deductions significantly lower the taxable income base, offsetting the higher tax rates.
