FAQ

DSC for personal use only — needed?

Mandatory for: filing IT returns above turnover threshold, GST, MCA, large court filings. Optional for individuals filing simple ITRs (Aadhaar OTP works).

Can DSC be transferred?

No — tied to your PAN + identity. New job / company = new DSC required.

PFX file vs USB token?

PFX (software) is portable, easier; USB token (hardware) is more secure (key never leaves token). Most professionals prefer USB token; small businesses use PFX for affordability.
