There is no government fee for GST registration on gst.gov.in. You pay only a professional fee if you use a consultant. With successful Aadhaar authentication, officers are expected to decide within 7 working days; without it, or where physical verification is needed, it can take up to 30 days.
Is GST registration free?
Yes. The GST portal charges nothing for registration or amendments. Any payment you make is a professional fee for preparing the application, choosing correct HSN or SAC codes, and handling officer queries. Be cautious of websites that present a professional fee as a government fee.

Budget for monthly or quarterly return filing and accounting. Late returns attract late fees per day and interest on unpaid tax. Keeping filings on time is the main recurring cost of being GST-registered.
Frequently asked questions
Can GST registration be done in one day?
Occasionally, when Aadhaar authentication succeeds and the system approves automatically, a GSTIN can be issued very quickly. However, this is not guaranteed. Plan for about a week, and longer if physical verification is triggered.
Is there a fee for GST amendments or cancellation?
No. Core and non-core amendments, and cancellation of registration, can be filed on the GST portal without any government fee. Only professional fees apply if you use a consultant.
What happens if I do not respond to a GST query?
If you do not reply to the REG-03 notice within the time allowed, the officer can reject the application in REG-05. You would then need to file a fresh application, restarting the timeline.
Is GST registration deemed approved if the officer does not act?
The law provides for deemed approval if the officer does not act within the prescribed period, but in practice most applications receive a decision or query in time. Tracking your ARN regularly is the best approach.
