Overview
What are DSC & DIN Services?
A Digital Signature Certificate (DSC) and Director Identification Number (DIN) are mandatory prerequisites for incorporating a company and filing compliance forms in India. A DIN is a unique number issued by the Ministry of Corporate Affairs to individuals who want to become company directors, and it remains valid for life. A Class 3 DSC is required for securely and digitally signing all documents and forms submitted on the MCA portal. Calcutta Corporate facilitates quick and hassle-free issuance of both DSCs and DINs, ensuring you are fully equipped for all your corporate and tax compliance needs.
Why do it
Key Benefits
Lifetime Validity of DIN
Your DIN is permanently tied to you as an individual, not the company, meaning it remains the same for your entire life even if you change companies.
Secure Online Transactions
A DSC ensures that all electronically transmitted documents are highly secure, authentic, and protected from tampering or unauthorized access.
Multi-Platform Utility
Beyond MCA filings, a Class 3 DSC can also be utilized for Income Tax returns, GST filings, and e-tenders.
Paperless Process
Digital signatures eliminate the need for physical paperwork, significantly speeding up document authorization and regulatory filings.
Rapid Issuance
With the modernized digital KYC process, DSCs and DINs can be obtained rapidly, minimizing delays in your business setup.
