How to Use a Digital Signature for MCA Filings (ROC, DIR, etc.)
In India, every company registered under the Companies Act is required to file statutory documents electronically with the Ministry of Corporate Affairs (MCA). These filings include forms related to company incorporation, director appointments, annual returns, and more. A key component of these filings is the digital signature.
If you're wondering how to use a digital signature for MCA filings such as ROC returns, DIR forms, and other electronic submissions, this guide will walk you through everything you need to know.
What Is a Digital Signature Certificate (DSC)?
A Digital Signature Certificate (DSC) is a secure digital key issued by Certifying Authorities (CAs) to authenticate the identity of the person signing electronic documents. It is legally valid under the Indian Information Technology Act, 2000. To get a DSC from a trusted provider, you can visit eSolutions.net.in, an authorized Certifying Authority.

Legal compliance under the Companies Act
Without a valid digital signature, MCA will not accept your e-forms.
