Example: Which Tax Regime Saves More Tax?
To evaluate whether the old vs new tax regime AY 2026–27 is more beneficial, a comparative computation based on actual income and eligible deductions is essential.
📊 Case Study
Mr. Raj (age 35) has a total income of ₹12,00,000. Under the old tax regime, he claims deductions including standard deduction of ₹50,000, Section 80C of ₹1,50,000, Section 80D of ₹25,000, and HRA exemption of ₹1,00,000, aggregating to ₹3,25,000. After reducing standard deduction and other deductions of ₹2,75,000, his taxable income amounts to ₹8,75,000. The tax liability is computed as ₹12,500 on income between ₹2.5 lakh and ₹5 lakh, and ₹75,000 on income between ₹5 lakh and ₹8.75 lakh, resulting in a total tax of ₹87,500.
Under the new tax regime, only the standard deduction of ₹75,000 is allowable. Accordingly, the taxable income is ₹11,25,000. The tax is calculated at ₹20,000 on income between ₹4 lakh and ₹8 lakh, and ₹32,500 on income between ₹8 lakh and ₹11.25 lakh, resulting in a total tax liability of ₹52,500.
📌 Comparative Result
The tax payable under the old regime is ₹87,500, whereas under the new regime it is ₹52,500, leading to a net tax saving of ₹35,000 under the new tax regime.
👉 Key Interpretation
The above computation indicates that, despite deductions of ₹3,25,000 under the old regime, the new tax regime results in a lower tax liability due to concessional slab rates and higher standard deduction. However, in cases where the aggregate deductions are significantly higher, the old regime may continue to be more beneficial.
