Tax Regime Compare — Frequently Asked Questions
Each question is answered directly below. Expand any item for the full response.
How do I decide between the old and new tax regime for FY 2024-25?
The new regime is the default and often works well when deductions are limited, while the old regime can still win if you claim substantial HRA, Section 80C, home-loan interest, and other eligible benefits. The best choice depends on your actual taxable income after all allowed adjustments.
What is one major feature of the new regime for salaried taxpayers?
The new regime generally allows the standard deduction for salary income and offers a wider low-tax slab structure at the lower end. It simplifies planning, but it does not reward deduction-heavy structuring in the same way as the old regime.
Who often benefits from the old regime?
Taxpayers with large housing-loan interest claims, rent-based HRA benefit, 80C investments, education-loan interest, or other eligible deductions often need to compare carefully. Without those claims, the old regime may lose its edge.
Should I choose a regime only from one year's tax outcome?
No, because your answer can change if salary, rent, bonus, home-loan interest, or investment declarations change. It is worth recalculating each financial year instead of assuming last year's result still applies.
Can I switch between old and new regime every year?
Salaried individuals can choose each financial year. Business income taxpayers have restrictions after opting out of old regime.
