Frequently Asked Questions
Yes. Income Tax uses FY 2025-26 New Tax Regime slabs including the ₹12 lakh rebate under Section 87A. EPF uses 8.25% interest. All GST calculators use current GST Council rates.
For income up to ₹12 lakh, New Regime is effectively tax-free (with rebate under Sec 87A). Above ₹12 lakh, it depends on your deductions — if you have significant 80C investments, HRA, and home loan interest, Old Regime may save more. Use the Income Tax Calculator to compare both for your exact income.
Take-Home = CTC minus Employee PF (12% of basic, up to ₹1,800/mo) minus Income Tax minus Professional Tax (state-wise) minus other deductions. Our calculator handles all of this, including state-wise PT and both tax regimes.
India has five GST slabs: 0% (essentials), 5% (basic necessities), 12% (processed food, computers), 18% (most services and goods), 28% (luxury items). For intra-state: CGST + SGST (split equally). For inter-state: full rate as IGST.
