GST registration has no government fee. This guide breaks down the real cost of getting a GSTIN in 2026 — professional fees, DSC, rent proof, Aadhaar authentication, physical verification and the cost of getting it wrong.
The government fee for GST registration is ₹0. Taxpex professional assistance starts from ₹999; signing tools or premises-document costs, where applicable, are separate. Approval depends on a complete application and the applicable verification process, not the fee paid.
| Component | Cost | Mandatory? |
|---|---|---|
| Government / portal fee | ₹0 | — |
| Taxpex professional fee | From ₹999 | Optional but recommended |
| Class 3 DSC (companies / LLPs) | ₹1,200–₹2,000 | Yes for companies and LLPs |
| Premises documentation | Depends on the arrangement and local requirements | Applicable proof; no blanket notarisation or NOC requirement |
| Aadhaar authentication | ₹0 | Follow the applicable portal authentication/verification workflow |
| Amendment after approval | ₹0 govt, from ₹499 professional | Only if details change |
Application signing and Aadhaar authentication are separate steps. Companies and LLPs use the authorised signatory's DSC; other applicants should use a signing method supported by the portal for their entity. Do not assume Aadhaar authentication removes every signing or verification requirement. DSC prices in this table are estimates, not a government registration fee.
Operating above the threshold without a GSTIN attracts a penalty of 10% of tax due (minimum ₹10,000), and 100% of tax due where evasion is deliberate. The cost of not registering dwarfs the cost of registering.
The portal fee is zero, but incomplete evidence can cost time. If a REG-03 clarification notice is issued, read the specific questions and response deadline, submit the requested explanation through the portal and track the decision. A notice is not itself a rejection. Check these items before filing:
| Entity | Documents |
|---|---|
| Proprietor | PAN, applicant/signatory details, required photograph, applicable premises evidence and identity-verification steps |
| Partnership / LLP | Firm PAN, constitution evidence, partner/signatory details, authorisation and applicable premises evidence; DSC for LLP |
| Private limited | COI, MOA/AOA, board resolution, director KYC, DSC, address proof |
Bank-account details are optional in the initial registration application according to the GST portal bank-account FAQ. This is not an indefinite exemption: Rule 10A generally requires bank details within 30 days of grant or before furnishing GSTR-1/IFF outward-supply details, whichever is earlier, with exceptions for registrations under Rules 12 and 16. Check the current Rule 10A for your registration category.
Use the GST document advisor and CBIC Instruction 03/2025-GST, dated 17 April 2025 for the applicable combinations. The instruction does not establish a universal two-month utility-bill rule or require every agreement to be notarised.
| Stage or case | What to expect |
|---|---|
| Preparation and submission | Check documents, signing and applicable authentication steps; track the ARN when generated |
| Ordinary complete application under Rule 9 | Seven working days for approval where the application and documents are in order |
| Specified physical-verification cases under Rule 9 | 30-day track, including specified non-authentication, risk-flagged and officer-directed verification cases |
| Clarification or additional verification | Track portal notices and respond by the applicable deadline; a quoted turnaround is not a guaranteed grant |
These are conditional statutory processing provisions, not a promised three-day approval. Aadhaar-authenticated applicants can also be selected for physical verification. See CGST Rule 9 and the GST Aadhaar authentication FAQs.
Budget for applicable documents and signing tools, complete the portal's required verification steps and monitor notices. Paying a higher professional fee does not buy faster government approval.
Registration is the cheap part. Once you hold a GSTIN, returns are compulsory even for nil months. GSTR-3B late fees run at ₹50 per day (₹20 per day for nil returns), plus 18% annual interest on unpaid tax. Budget for monthly or quarterly filing from the day your GSTIN is issued.
