Frequently Asked Questions

Which is better - Old or New tax regime?

For most individuals with income up to ₹12 Lakh, the new regime is better (zero tax due to rebate). If you have significant deductions (80C, HRA, home loan interest > ₹2L), old regime may be better. Use this calculator to compare both.

What is Section 115BAA?

Section 115BAA allows domestic companies to pay tax at 22% (+ surcharge + cess) if they forgo certain deductions and exemptions. The effective tax rate becomes about 25.17%. Once opted, it cannot be withdrawn.

Should I opt for presumptive taxation?

If your actual profit margin is less than 6-8% (for business) or 50% (for profession), presumptive taxation may result in higher tax. Calculate both ways before opting. Once opted, you must continue for 5 years.
