Old vs New Tax Regime: Which One Saves You More?
Compare tax liability under both regimes instantly
The Indian government offers two tax regimes: the old regime with multiple deductions (80C, 80D, HRA) and the new regime with lower tax rates but fewer exemptions. Our Income Tax Calculator helps you compare both side-by-side based on your income and deductions, so you can make an informed decision for FY 2025-26.

Real-World Example: Rahul the Engineer
Rahul
Rahul works as a software engineer in Bengaluru with an annual salary of ₹15,00,000. He invests ₹1,50,000 in 80C instruments, pays ₹30,000 for health insurance, and receives HRA.
Annual Income: ₹15,00,000
Section 80C: ₹1,50,000
Section 80D: ₹30,000
Standard Deduction: ₹50,000
Rahul wanted to know which tax regime would save him more. He entered his income and deductions into the calculator and compared both regimes side by side.
Under the old regime, his tax was ₹1,01,400. Under the new regime, it was ₹1,35,200.
The old regime saves Rahul ₹33,800 per year because his total deductions significantly reduce his taxable income.
Rahul chose the old regime and redirected his savings into an emergency fund. He now plans his investments each year to maximize his 80C limit.
Tax Calculation Formula
Understanding how your tax is calculated helps you plan better.
Gross Income Total annual income from all sources (e.g. ₹12,00,000). Standard Deduction Fixed deduction of ₹50,000 (old) or ₹75,000 (new) (e.g. ₹50,000). 80C Deductions Investments in PPF, ELSS, EPF, life insurance (max ₹1,50,000) (e.g. ₹1,50,000).
Taxable Income: Gross Income − Standard Deduction − Eligible Deductions = Taxable Income

| Feature | Old Regime | New Regime |
|---|---|---|
| Standard Deduction | ₹50,000 | ₹75,000 |

Choose the old regime if you have significant deductions and investments. Choose the new regime for simplicity and lower rates if you have few deductions.
Common Tax Misconceptions
Clear up confusion about how taxes work in India.
- Misconception: The new regime is always better because of lower tax rates.. Reality: While the new regime has lower tax slabs, it disallows most deductions. For taxpayers with significant investments, the old regime can still result in lower tax. You could pay more tax by blindly choosing the new regime without calculating your specific situation.
- Misconception: All my income is taxed at the slab rate I fall in.. Reality: India follows a marginal tax rate system. Only income within each slab is taxed at that rate. If you earn ₹12,00,000, only the amount above ₹10,00,000 is taxed at 30%. Understanding marginal rates prevents overestimating your tax and helps with salary negotiations.
- Misconception: I should always maximize 80C deductions even if it means poor investment returns.. Reality: Invest based on financial goals, not just tax savings. Locking money in low-return instruments for tax benefits may not be optimal. Focus on post-tax returns and liquidity needs rather than just tax minimization.
