Frequently Asked Questions

Which is better - old or new regime?
It depends on your deductions. If total deductions (80C + 80D + HRA + others) exceed ₹3-4 lakh, old regime is usually better. Otherwise, new regime with lower rates may save more tax. Use this calculator to compare for your specific situation.
Can I switch between regimes every year?
Yes, salaried individuals can switch between old and new regime every year. However, business/professional income can switch only once. Choose the regime that gives lower tax each year based on your investments and deductions.
What are the key differences?
Old regime: Higher rates but allows deductions (80C, 80D, HRA, 24b, etc.). New regime: Lower rates but no deductions except ₹75K standard deduction. New regime has rebate up to ₹7L income (zero tax).
What is the default tax regime?
New tax regime is the default from FY 2024-25. If you want to use the old regime, you must explicitly opt for it. Salaried individuals can choose either regime each year. Business/professionals can switch only once.
How to decide which regime to choose?
Calculate tax under both regimes using this calculator. Consider all your current and planned investments. If you are heavily invested in 80C instruments and have HRA, old regime may be better. If you have minimal deductions, new regime is likely better.
