Difference Between Old vs. New Tax Regime (2025): Which One Should You Choose? — A Complete Guide
Income tax is one of the most important parts of financial planning for every Indian taxpayer. After the introduction of the New Tax Regime under Section 115BAC, taxpayers often get confused about which regime is better for them — Old Tax Regime or New Tax Regime.
Both regimes offer different benefits, tax slabs, and deductions. Selecting the right one can help you save thousands of rupees every year.
This detailed 3000-word guide explains every important difference between the two regimes so that you can make the best financial decision.
What Is the Old Tax Regime?
The Old Tax Regime is the traditional income tax system in India that allows taxpayers to claim more than 70 deductions and exemptions, such as:
-
Standard Deduction
-
HRA (House Rent Allowance)
-
LTA (Leave Travel Allowance)
-
Section 80C (LIC, PF, ELSS, PPF, etc.)
-
Section 80D (Health Insurance)
-
Section 24(b) (Home Loan Interest)
-
Section 80E (Education Loan Interest)
-
Section 80G (Donations)
Tax slabs are slightly higher, but due to heavy deductions, taxpayers with smart tax planning often pay lower taxes.
This regime is ideal for salaried employees who claim multiple exemptions and invest regularly.
What Is the New Tax Regime?
The New Tax Regime, introduced in Budget 2020, offers lower tax rates but removes most deductions and exemptions.
Initially optional, the New Regime was made default from FY 2023–24, which means if you do not choose the old regime, the new one will automatically apply.
The government’s aim:
➡️ Simplify tax structure
➡️ Reduce paperwork
➡️ Encourage transparent taxation
The new regime is beneficial for individuals who do not invest much and want lower tax rates without documentation.

Real-Life Tax Comparison Examples
Example 1: Income ₹10 lakh
New Regime Calculation
-
After standard deduction: ₹9,50,000 taxable
-
Tax approx.: ₹54,600
Old Regime Calculation
Assume claiming:
-
80C: ₹1,50,000
-
80D: ₹25,000
-
Standard deduction: ₹50,000
Taxable income = ₹10,00,000 − ₹2,25,000 = ₹7,75,000
Tax approx.: ₹40,500
➡️ Old Regime saves more tax for someone who invests.
Example 2: Income ₹12 lakh
If NO deductions claimed → New Regime wins
If claiming 80C + HRA + 80D → Old Regime wins
Example 3: Income ₹7 lakh (Rebate Section 87A)
New Regime
Tax = 0 for income up to ₹7 lakh.
Old Regime
Tax = 0 only if deductions reduce income below ₹5 lakh.
➡️ For non-investors, New Regime > Old Regime
