The Core Difference: Old vs. New Regime

To make the right choice, you need to understand the fundamental philosophy behind each option.

1. The New Tax Regime (The “Default”)

This is a simplified tax structure with lower tax rates but almost no deductions.

• Pros: Lower tax slabs, no need to lock money in investment schemes, simple filing.
• Cons: You cannot claim HRA, LTA, 80C, or 80D.
• Note: The Standard Deduction of ₹50,000 IS available in the New Regime for salaried employees.

2. The Old Tax Regime (The “Investment” Route)

This uses the older, higher tax rates but allows you to reduce your taxable income using exemptions.

• Pros: Great for people with Home Loans, HRA, and heavy investments.
• Cons: Higher tax rates if you don’t have enough deductions.

The “Breakeven” Rule: When Should You Choose Old?

The most common question we get is: “How much do I need to invest to make the Old Regime better?”

Mathematically, the breakeven point usually lies around ₹3.75 Lakhs in total deductions.

• If your total deductions (HRA + 80C + 80D + Home Loan) are LESS than ₹3.75 Lakhs: The New Regime is usually better for you.
• If your total deductions are MORE than ₹3.75 Lakhs: The Old Regime will likely save you more tax.
