Frequently Asked Questions
What is the difference between old and new tax regime?
The old regime has higher tax rates but allows deductions (80C, 80D, HRA, etc.). The new regime has lower tax rates and higher rebate limits but most deductions are not available. You should compare both to choose the more beneficial one.
What are the new regime tax slabs for FY 2024-25?
New regime slabs: ₹0-3L: Nil, ₹3L-7L: 5%, ₹7L-10L: 10%, ₹10L-12L: 15%, ₹12L-15L: 20%, Above ₹15L: 30%. Section 87A rebate makes income up to ₹7L tax-free.
Which tax regime should I choose?
If your total deductions (80C + 80D + HRA + others) exceed approximately ₹3.75 lakh, the old regime may be more beneficial. For lower deductions, the new regime with its lower slab rates is usually better. Use this calculator to compare both.
