Digital Signature Certificate (DSC) in India
A Digital Signature Certificate is your legally valid electronic signature. Directors and authorised signatories need it to file with the MCA, sign company documents, and — for companies and LLPs — file GST and income tax returns.
Most statutory filings require a Class 3 DSC, typically valid for one to three years. It is a small but essential piece of infrastructure that stalls filings the moment it expires.
Key features and requirements
- Legally valid electronic signature for online filings
- Class 3 DSC is required for most MCA, GST and income tax filings
- Typically valid for 1–3 years, then renewed
- Issued on a secure USB token
- Needed by every director/authorised signatory who signs filings
