How to use this calculator

Follow these 5 steps for an accurate result.

  1. 1

    Pick primary use case

    MCA filing / IT e-filing / GST portal / DGFT / all — each CA is licensed by CCA.

  2. 2

    Pick class type

    Class 2 (database-verified identity) or Class 3 (in-person / video-KYC verified identity).

  3. 3

    Flag combo (signing + encryption)

    Required for filing e-TDS / e-TCS encrypted attachments.

  4. 4

    Pick validity years

    1 / 2 / 3 years. Longer is cheaper per year.

  5. 5

    Read verdict + estimated cost

    See "Class 2 / 3 / Class 3 Combo" + estimated cost for the validity period.

Key takeaways

  • Class 3 DSC is mandatory for DGFT / ICEGATE filings — Class 2 is rejected by the DGFT portal.
  • Combo DSC has both signing + encryption keys — required for filing e-TDS / e-TCS encrypted attachments.
  • Class 3 DSC works on all portals + new filings — the safer default when you file across MCA + IT + GST + DGFT.
  • DSC validity options: 1 / 2 / 3 years. Longer validity is cheaper per year but risky if the underlying PAN changes.

Frequently asked questions

Quick answers to common questions about digital signature certificate (dsc) picker.

Which Certifying Authority should I buy from?

eMudhra + TCS + n-Code are the largest licensed CAs in India. All three are accepted on MCA / IT / GST portals. eMudhra is the largest + most widely supported. Compare prices — they vary within ₹100-200 for the same class.

How long does DSC issuance take?

Class 2: instant (after Aadhaar OTP verification). Class 3: 1-3 days (video KYC scheduling). PAN + Aadhaar + mobile OTP + video (Class 3 only) required.

What if my DSC expires during a filing window?

Expired DSC means you cannot sign the filing. Renew 7 days before expiry to avoid filing delays. Most CAs send expiry reminders 30 / 15 / 7 days before.

Is combo DSC mandatory for IT returns?

No. Combo DSC is required only for e-TDS / e-TCS statements (which use encryption). ITRs + audit reports use signing-only DSC.
