With the new income tax regime comes the confusion of which one to choose. The new regime is beneficial for some, and for some, the old one. Therefore, you must know everything about the old regime vs new regime.

Exemptions and Deductions in Old and New Income Tax Regimes
The meaning of “exemption” is that a taxpayer is unbound to pay tax up to a certain income level. At the same time, “Deduction” means debiting certain investments and expenses from a taxpayer’s income to calculate the taxable income.
These exemptions and deductions are not identical in new and old income tax regimes. The existing or old tax regime had 120 exemptions and deductions, most of which complicated the tax calculation. Therefore, the Ministry of Finance repealed 70, keeping 50 available.
The table below shows the comparison of exemptions available in the new tax regime and in the old tax regime for both FY 2024-25 and FY 2025-26:

How to Choose Between the New and Old Income Tax Regime?
Taxpayers often wonder how to choose between old and new tax regimes. You must calculate your payable tax in both regimes to determine which is more beneficial. Below are some scenarios of individuals with different incomes and investments. The calculations compare new and old income tax slabs for FY 2025-26 for a particular income.
Scenario 1:
Annual income = ₹12,00,000
The expense for Life Insurance premiums (per annum) = ₹50,000
Contribution towards EPF (per annum) = ₹30,000
Here’s how to calculate the net taxable income as per both regimes based on the given numbers for FY 2025-26:
Calculation of Net Taxable Income - FY 2025-26 (AY 2026-27)
Now, let us calculate the income tax for both regimes:
So, in this scenario, choosing the new regime is a wise decision for the taxpayer.
Scenario 2:
This scenario shows the new versus old tax regime slab rate if the annual income is above ₹24 lakhs.
Annual income = ₹25,00,000
Expense for Life Insurance premiums (per annum) = ₹90,000
Contribution towards EPF (per annum) = ₹40,000
Here’s how to calculate the net taxable income as per both regimes if your income is ₹25 lakhs:
Calculation of Net Taxable Income - FY 2025-26
Now, let us calculate the income tax for both regimes:
Income Tax Calculation (Old Regime vs New Regime) - FY 2025-26
In this scenario, the new regime again becomes more beneficial for the taxpayer.
Thus, here is a final breakdown of calculations to help you choose the right income tax regime for FY 2025-26:
- Choose the new tax regime if your total deductions are ₹1.5 lakhs or less.
- Choose the old tax regime if your total deductions are more than ₹3.75 lakhs.
- If your total deductions are between ₹ 1.5 lakhs and ₹3.75 lakhs, choose the tax regime depending on your income level.
Hence, you must consider all your deductions and exemptions before choosing between the old and new income tax. After all exemptions and deductions under the old regime, calculate the net taxable amount. If it is lower than the amount under the new regime, choosing the old one is wise, and vice versa.
