GST Registration Cost: Is It Actually Free?
The key question: if GST registration is free on the government portal, why does every CA firm quote a fee for it?
Because “free” only covers the government’s own charge — it says nothing about the time and expertise that goes into getting your application right the first time. This guide separates the two so you know exactly what you’re paying for when you see a quote.
1. Think of it like filing your own taxes versus hiring an accountant
The income tax portal doesn’t charge you to file your own return — it’s free. But most people still pay an accountant, not for portal access, but for the judgment that keeps them from making an expensive mistake. GST registration works the same way.
What's actually free vs what you're paying for
2. What a typical professional fee actually covers
Where the fee goes
Typical professional fees for a straightforward GST registration range from ₹500 to ₹2,500 for a simple proprietorship, and somewhat more for companies or LLPs where the constitution documents and digital signature requirements add complexity.
Surprise most people miss: the “cost” of a bad DIY filing usually isn’t the ₹0 saved on professional fees — it’s the 2-3 weeks of delay from an officer query on a mismatched address or wrong HSN code, which can be far more expensive in lost business time than the fee would have been.
3. A worked example: DIY versus assisted
A small trader files GST registration himself to save the professional fee, entering his shop address slightly differently from what’s on his electricity bill.

Two extra weeks pass before GSTIN is finally issued
Meanwhile, a B2B client waiting for his GST invoice moves the order to a competitor who was already registered. The ₹1,500 he saved on professional fees ends up costing far more in lost business — not a guaranteed outcome every time, but a real risk that the fee is meant to reduce.
4. Costs that sometimes get bundled or missed
- Digital signature — required for companies and LLPs, typically ₹1,000–₹1,500 per authorized signatory, separate from the GST filing fee itself.
- Amendment filings — if your business constitution or address changes later, an amendment filing usually carries its own smaller professional fee.
- Composition Scheme evaluation — some CAs include a quick assessment of whether you should file under the Composition Scheme as part of the registration engagement; others bill it separately.
Easy rules to remember
Safe: treating the professional fee as paying for accuracy and speed, not portal access — the portal itself is free regardless of who uses it.
Risky: filing DIY specifically to save a modest fee, without factoring in the cost of a delay if something is entered incorrectly.
Safer still: asking upfront exactly what’s included in a quoted GST registration fee — document review, HSN classification, and query handling should all be part of it, not billed as extras later.
