Old vs New Tax Regime: The Ultimate Guide for FY 2025-26

Understanding the Twin Tax Systems

Since the introduction of the New Tax Regime, salaried taxpayers face a dilemma every year: should I stick to the Old Regime with all its deductions, or switch to the New Regime for lower rates but fewer exemptions?

The New Tax Regime (Default)

The government has made the New Tax Regime the default option. It offers:

• Lower tax slabs.
• A massive ₹12 Lakh tax-free threshold (via Section 87A rebate).
• A ₹75,000 standard deduction for salaried individuals.

However, you must forego HRA, LTA, 80C (PPF, ELSS, LIC), 80D (Health Insurance), and Section 24B (Home Loan Interest).

The Old Tax Regime

The Old Regime maintains higher slab rates but allows you to reduce your taxable income drastically. If you are paying a hefty home loan EMI and rent (HRA), your taxable income can be brought down significantly.

The Break-Even Point

Generally, if your salary is below ₹12.75 Lakhs, the New Regime is a no-brainer (Zero tax). If your salary is higher, say ₹15 Lakhs or ₹20 Lakhs, you need to calculate your total deductions.

If your total deductions (80C + 80D + HRA + Home Loan) exceed ₹3.75 to ₹4 Lakhs, the Old Regime usually results in lower tax. Try our Old vs New Tax Regime Calculator to run your exact numbers.
