Why DSC for Income Tax
Why DSC Is Required on the Income Tax Portal
The Income Tax portal (incometax.gov.in) requires DSC for mandatory company ITR filing, Tax Audit reports, and Form 15CA/CB for foreign remittances. Under the Income Tax Act, companies and LLPs must mandatorily e-file ITR with DSC.
⚠️ Mandatory by law: Section 140 of the Income Tax Act mandates that ITR filed by companies must be signed using DSC. A return filed without DSC for a company is treated as invalid.

FAQ
DSC for Income Tax — Frequently Asked Questions
Yes. Section 140 of the Income Tax Act 1961 mandates that company ITR (ITR-6) and LLP ITR (ITR-5) must be filed with DSC. Filing without DSC makes the return invalid. Individual taxpayers have the option to use OTP/EVC or DSC.
No. The DSC used must belong to the authorised signatory of the company (Director/Partner). CAs use their own DSC for Tax Audit reports (Form 3CB/3CD) and Form 15CB. Each DSC is tied to a specific PAN.
After getting your DSC, plug the USB token, install drivers, and go to incometax.gov.in → My Profile → Register DSC. Select your PAN from the certificate and authenticate. We walk you through this at our BBD Bagh office.
This usually means the PAN on your DSC certificate doesn't match the PAN registered on the portal, or the DSC has expired. Walk-in at our office — we diagnose and fix in 15 minutes.
2-year validity is recommended — it covers two ITR filing seasons (March-July) and costs ₹840+GST. For CA firms filing for multiple clients, 3-year validity (₹1,260+GST) offers the best value.
