MCA V2 Portal vs. MCA V3 Portal

The MCA portal has evolved significantly. The Ministry of Corporate Affairs (MCA) officially launched the MCA V3 portal on 24 May 2021, with its complete shift from 14 July 2025.

While MCA V2 served companies for years, the new MCA V3 portal introduces enhanced security, a modern interface, and streamlined DSC workflows. Knowing the differences helps ensure smooth filings.

Key Differences:

1. Forms

MCA V2 Portal: In MCA V2, users had to download PDF forms, fill them offline, and then upload them.

MCA V3 Portal: MCA V3 has fully web-based forms that can be filled out directly in the browser.

2. Saving In-progress Forms

MCA V2 Portal: V2 didn't allow saving partially completed forms, so users had to complete everything in one go.

MCA V3 Portal: V3 now auto-saves your progress for complex forms like AOC-4 or MGT-7. An offline Excel utility is also given.

3. Data Entry

MCA V2 Portal: Previously, all information had to be entered manually for each form.

MCA V3 Portal: V3 now pre-fills many fields using existing company data, reducing manual work and errors.

4. Filing Structure

MCA V2 Portal: V2 treated each form separately.

MCA V3 Portal: V3 introduces a linked filing system, so related forms, like AOC-4 and CSR-2, are submitted together as a single process.

5. Error Checking

MCA V2 Portal: In V2, errors were detected only after uploading, often causing rejections and repeated filings.

MCA V3 Portal: V3 now validates your inputs in real time, minimizing mistakes and delays.

MCA Associate DSC V3

A Digital Signature Certificate (DSC for MCA) is essential for authenticating filings on the MCA V3 portal. But before you can submit any e-forms, your DSC must be associated with your MCA account. This process is known as DSC association.
