FAQ

Answers, in plain English.

Do I still need to log in at incometax.gov.in?
Yes. Simplifile prepares the JSON file your return is built on — you'll upload that to the official income-tax portal and e-verify there. We don't (and won't) ask for your portal credentials.
Which assessment years are supported?
AY 2025-26 (for income earned in FY 2024-25) and AY 2026-27 (FY 2025-26). The new-regime slabs and rebate thresholds for AY 2026-27 are already in place.
What's the difference between ITR-1 and ITR-4?
ITR-1 (SAHAJ) is for resident salaried filers with up to one house property and standard other-sources income. ITR-4 (SUGAM) covers presumptive business and profession income under sections 44AD, 44ADA, and 44AE. Both cap at ₹50 lakh total income.
Is my Form 16 data uploaded anywhere?
No. Parsing happens entirely in your browser. The PDF and every value extracted from it stays on your device, full stop.
How accurate is the regime comparison?
Calculations follow CBDT rules for both regimes, including standard deduction, 87A rebate, 4% cess, and surcharge slabs. The comparison number is the actual tax payable under each regime given everything you've entered.
Does Simplifile cost anything?
Drafting and exporting a valid JSON is free. You don't need an account for that. Paid features — if and when added — will be opt-in and won't change the free flow.
