GST registration — the government fee is ₹0
There is no government charge for a normal GST registration — the entire application on the GST portal is free. Filing the application, generating the ARN, replying to any clarification from the officer and the issue of your GSTIN all cost ₹0 in government fees. Government fees only — professional fees are not included.

Key terms explained
Government fee
The GST portal charges nothing to register. Any "GST fee" you are quoted elsewhere is not a tax or fee paid to the government.
Class-3 DSC
A Digital Signature Certificate used to sign the GST application electronically. Private companies and LLPs must sign with DSC; a proprietor can usually verify with Aadhaar OTP instead.
ARN
The Application Reference Number generated after you submit the GST application. Use it to track the status until the GSTIN is issued.
Clarification (REG-03)
If the officer needs more information, a notice is issued and the reply is filed on the portal — again with no government fee.
Questions people ask
Short answers on GST Registration Cost. Tap a question to open it.
01Is there a government fee for GST registration?
No. The GST portal charges nothing for a fresh registration, so the government cost is ₹0. A company or LLP must also sign the application with a Class 3 digital signature, which is bought separately from a certifying authority.
02Why do I need a DSC for GST registration?
Companies and LLPs must sign the application with a Class 3 DSC of an authorised signatory. Proprietors and partnerships can use EVC through the Aadhaar-linked mobile number instead, which avoids the DSC cost.
03How long does GST registration take?
Usually 7 to 15 working days where Aadhaar authentication succeeds. Cases flagged for physical verification of premises, or where a query in REG-03 is raised, take longer.
04Do I need a separate registration for each state?
Yes. GST registration is state-wise, so a business with a place of business in three states takes three registrations against the same PAN, and each files its own returns.
05What ongoing cost follows registration?
Monthly or quarterly return filing, the annual return where turnover exceeds the threshold, and the accounting work behind them. Registration itself is free, but compliance is the recurring cost worth budgeting for.
