GST registration in India is governed by Sections 22 to 30 of the Central Goods and Services Tax Act, 2017 ('CGST Act') and Rules 8 to 26 of the Central Goods and Services Tax Rules, 2017 ('CGST Rules'). A non-risky application must be approved within 7 working days under CBIC Instruction No. 03/2025-GST (INS_03_2025); Rule 9A allows fully electronic grant in 3 working days from 1 November 2025. Bank account details fall due within 30 days of grant, and missing them suspends the GSTIN automatically.
Founder TL;DR
Registration is no longer the hard part — Instruction 03/2025-GST tells the officer exactly which documents he may ask for and gives him 7 working days. The hard part is the two automatic tripwires that follow. Furnish bank account details within 30 days of grant or your GSTR-1 is blocked and your GSTIN is suspended. And if a cancellation order ever lands, the revocation clock is 90 days from service — extendable by 180, but only if you ask in writing with a reason.
Getting in: who must register, who need not
Section 22 of the CGST Act sets the turnover-based liability; Section 24 imposes compulsory registration on eleven categories regardless of turnover, including inter-State suppliers, casual taxable persons, reverse-charge recipients, e-commerce operators and persons required to deduct tax at source under Section 51. Section 23 then lets the Government exempt classes of person by notification, and this is where the practically important carve-outs live:
- Small inter-State service suppliers. Notification No. 10/2017-Integrated Tax (
IGST_10_2017) exempts persons making inter-State taxable supplies of services with all-India aggregate turnover up to ₹20 lakh (₹10 lakh for special category States other than Jammu & Kashmir). This is the provision that keeps consultants and freelancers with cross-border clients out of the net. It does not extend to goods. - Job workers. Notification No. 07/2017-Integrated Tax (
IGST_07_2017) exempts job workers making inter-State supplies of services to a registered person — unless independently liable under Section 22(1), voluntarily registered under Section 25(3), or dealing in the jewellery and goldsmiths' wares at serial 151 of the Rule 138 Annexure. - Casual handicraft sellers. Notification No. 56/2018-Central Tax (
CGST_56_2018), which replaced Notification No. 32/2017-Central Tax, exempts casual taxable persons supplying notified handicraft goods inter-State up to the Section 22(1) threshold, subject to holding a PAN and generating e-way bills. - Small suppliers on e-commerce platforms. Notification No. 34/2023-Central Tax (
CGST_34_2023) exempts small unregistered suppliers making intra-State supplies through an electronic commerce operator, effective 1 October 2023. Conversely, Notification No. 24/2024-Central Tax (CGST_24_2024) removed metal scrap suppliers (Customs Tariff Chapters 72 to 81) from the reverse-charge-only exemption in Notification No. 5/2017-Central Tax from 10 October 2024.
Registration is applied for in FORM GST REG-01 on www.gst.gov.in, notified as the Common GST Electronic Portal by Notification No. 09/2018-Central Tax (CGST_09_2018) under Section 146 of the CGST Act. A person with multiple places of business in one State may take a separate registration for each under Rule 11 as substituted by Notification No. 03/2019-Central Tax (CGST_03_2019) — with the trap that if any one such place becomes ineligible for composition, all the others do too.
The Aadhaar layer
Rule 8(4A), inserted by Notification No. 16/2020-Central Tax (CGST_16_2020) with effect from 1 April 2020, requires Aadhaar authentication at application stage; failure routes the application to physical verification under Rule 25, and deemed approval under Rule 9(5) does not apply. Notification No. 26/2022-Central Tax (CGST_26_2022) added risk-based biometric authentication for flagged applicants, rolled out State by State, and Notification No. 35/2021-Central Tax (CGST_35_2021) extended Aadhaar authentication to already-registered persons through Rule 10B, which gates refund and revocation applications.

The biometric-authentication rollout is a State-by-State chain of amending notifications running from 27/2022 through 31/2023 and 13/2024. Veritect Legal AI resolves that chain to a single answer — which States require biometric authentication as at a given date — instead of leaving you to reconcile four notifications by hand.
What an officer may and may not ask
CBIC Instruction No. 03/2025-GST, issued on 17 April 2025, supersedes Instruction No. 03/2023-GST and is the cleanest statement of the officer's limits. Principal-place-of-business proof is satisfied by any one of the FORM GST REG-01 list — latest property tax receipt, municipal khata copy, or electricity bill — or a comparable State or local-law document such as a water bill; rented premises add the rent or lease agreement, and a registered agreement removes even the need for lessor identity proof. Constitution proof for a partnership is the partnership deed alone — no Udyam, MSME, shop establishment or trade licence.
Paragraph 7 proscribes presumptive queries outright: residence of the applicant or authorised signatory in a different city or State, a claim that an HSN code is prohibited for sale in the State, or a view that the declared activity cannot be conducted from the premises. Notices in FORM GST REG-03 are limited to four grounds — illegible document, address mismatch, incomplete or vague address, and a cancelled or suspended GSTIN linked to the PAN. Where an applicant is nonetheless obstructed, Instruction No. 04/2025-GST (INS_04_2025), dated 2 May 2025, provides a zonal email-based grievance escalation route.
Notification No. 18/2025-Central Tax (CGST_18_2025) then added two fast tracks with effect from 1 November 2025: Rule 9A, an electronic grant within 3 working days for applicants cleared on data analysis and risk parameters, and Rule 14A, a simplified registration for applicants whose monthly output tax liability on supplies to registered persons stays under ₹2,50,000 — Aadhaar-authenticated, 3 working days, one per PAN per State, exit via new FORM GST REG-32 with the order in FORM GST REG-33.
Amendment, suspension and the bank-account tripwire
Post-registration changes go through FORM GST REG-14 under Rule 19. The obligation that most often catches new registrants is Rule 10A: as amended by Notification No. 38/2023-Central Tax (CGST_38_2023), bank account details are due within 30 days of grant or before filing FORM GSTR-1 or using the invoice furnishing facility, whichever is earlier — replacing the earlier 45-day window. Two automatic consequences follow non-compliance: Rule 59(6)(f) blocks GSTR-1, and Rule 21A(2A)(b) suspends the registration.
Rule 21A itself was inserted by Notification No. 03/2019-Central Tax: suspension is deemed on filing a cancellation application, the officer may also suspend where cancellation appears warranted, and a suspended person may make no taxable supply and need not file returns under Section 39 of the CGST Act. Sub-rule (2A) added system-triggered suspension where FORM GSTR-3B diverges materially from FORM GSTR-1 or supplier-derived inward supply data. Circular No. 145/01/2021-GST (CIR_145_2021) sets the SOP — intimation in FORM GST REG-31, reply in FORM GST REG-18 within 30 days, then either FORM GST REG-20 (dropped, GSTIN Active) or FORM GST REG-19 (cancelled suo motu). A Rule 10A breach alone is revoked automatically on compliance.
Getting out: cancellation, final return, revocation
Voluntary cancellation is applied for in FORM GST REG-16 under Section 29 read with Rule 20, within 30 days of the triggering event — discontinuance, transfer on amalgamation or sale, change of constitution altering the PAN, ceasing to be liable, or death of a sole proprietor. Circular No. 69/43/2018-GST (CIR_69_2018) directs officers to accept within 30 days, with only two grounds for reverting to the applicant (an incomplete REG-16, or a transferee not yet registered in a merger case), each curable in seven working days. The effective date is the date the applicant asks for, and cannot precede the application.
Two points routinely misunderstood: reversal under Section 29(5) is not a precondition for applying — it is discharged in the final return; and the final return in FORM GSTR-10 is due within three months of the effective cancellation date or the order date, whichever is later, under Section 45 of the CGST Act, with late fee of ₹200 per day under Section 47. Notification No. 58/2018-Central Tax (CGST_58_2018) is the historical extension for registrations cancelled on or before 30 September 2018; registration for tax deduction at source under Section 51 has its own procedure, refined by Notification No. 33/2019-Central Tax (CGST_33_2019).
Revocation of a suo motu cancellation runs on Section 30 and Rule 23. The operative window since 1 October 2023 is 90 days from service of the cancellation order, extendable by up to a further 180 days by the Commissioner or an officer not below Additional or Joint Commissioner rank, on sufficient cause recorded in writing — both changes made by Notification No. 38/2023-Central Tax. Circular No. 148/04/2021-GST (CIR_148_2021) sets out the escalation SOP under the earlier 30-day-plus-two-extensions regime, and remains useful for what a "sufficient cause" application must contain. The 2023 amnesty in Notification No. 03/2023-Central Tax (CGST_03_2023) is closed; its conditions nonetheless state the enduring principle — clear all returns, tax, interest, penalty and late fee up to the effective date first, then apply.
Practitioner implications
Diarise 30 days from grant, not from first invoice. The Rule 10A clock runs from the date of grant, and the consequence of missing it is suspension, not a query.
Treat a REG-31 as a 30-day litigation window. The reply in FORM GST REG-18 is the entire record the officer decides on. Where suspension is return-driven, file the returns and reply; filing alone does not close the proceeding.
Quote Instruction 03/2025 back at an over-reaching REG-03. The paragraph 6 document list and the paragraph 7 prohibition on presumptive queries are directly citable, and Instruction 04/2025 gives a named escalation channel before writ becomes necessary.
Calendar the revocation deadline the day the order is served. 90 days plus a possible 180 is generous only if the extension is requested in writing with a substantive cause. Silence for 91 days converts a procedural problem into a fresh-registration problem — the old GSTIN then shows as a cancelled registration linked to the PAN, itself a valid REG-03 ground.
Frequently Asked Questions
Q: How long does GST registration take in India?
A: For a non-risky application, 7 working days from submission — Instruction No. 03/2025-GST fixes that timeline. Where the applicant has not opted for Aadhaar authentication, is flagged as risky, or the officer considers verification essential, registration follows physical verification under Rule 25 of the CGST Rules within 30 days. Rule 9A, effective 1 November 2025, additionally allows the common portal to grant registration electronically within 3 working days for applicants cleared on data analysis and risk parameters.
Q: What documents can a GST officer legitimately demand for principal place of business proof?
A: Only what FORM GST REG-01 lists. Instruction No. 03/2025-GST restricts the officer to any one of the latest property tax receipt, municipal khata copy, or electricity bill of the owner (or a comparable State or local-law document such as a water bill), plus a rent or lease agreement for rented premises. Lessor PAN, lessor Aadhaar and photographs inside or outside the premises may not be demanded. Off-list documents require Deputy or Assistant Commissioner approval.
Q: When must I furnish bank account details after getting registered?
A: Within 30 days of the grant of registration, or before furnishing outward supply details in FORM GSTR-1 or through the invoice furnishing facility, whichever is earlier — Notification No. 38/2023-Central Tax replaced the earlier 45-day window with this test. Non-compliance blocks GSTR-1 under Rule 59(6)(f) and triggers suspension under Rule 21A(2A)(b) of the CGST Rules.
Q: My GSTIN shows "Suspended" — what happened and what is the clock?
A: Suspension under sub-rule (2A) of Rule 21A of the CGST Rules is triggered either by anomalies between FORM GSTR-3B and FORM GSTR-1 or supplier-derived inward supply data, or by failure to furnish bank account details under Rule 10A. Circular No. 145/01/2021-GST prescribes intimation in FORM GST REG-31 and a 30-day window to reply in FORM GST REG-18. The officer then drops proceedings in FORM GST REG-20 or cancels in FORM GST REG-19. Suspension arising from Rule 10A alone is revoked automatically on compliance.
Q: How long do I have to apply for revocation of a cancelled GST registration?
A: 90 days from service of the cancellation order, under Rule 23(1) of the CGST Rules as amended by Notification No. 38/2023-Central Tax with effect from 1 October 2023. The Commissioner, or an officer not below Additional or Joint Commissioner rank, may extend by up to a further 180 days on sufficient cause shown in writing. The earlier regime was 30 days extendable to 90 under Section 30 of the CGST Act, which is the context of Circular No. 148/04/2021-GST.
Q: Does cancelling my GST registration wipe out my pending liabilities?
A: No. Circular No. 69/43/2018-GST is explicit that cancellation does not affect any outstanding GST liability, determined before or after cancellation. Section 29(5) of the CGST Act requires reversal on stock of inputs, semi-finished goods, finished goods and capital goods held the day before the effective date — the higher of credit in stock or output tax on those goods — discharged in the final return FORM GSTR-10, due within three months of the effective cancellation date or the order date, whichever is later.
Q: What is the new simplified registration route under Rule 14A?
A: Rule 14A of the CGST Rules, inserted by Notification No. 18/2025-Central Tax with effect from 1 November 2025, lets an applicant whose total monthly output tax liability on supplies to registered persons does not exceed ₹2,50,000 opt for simplified electronic registration, granted within 3 working days on successful Aadhaar authentication. Applicants who have not opted for Aadhaar authentication are excluded, and only one such registration per PAN per State or Union Territory is permitted. Exit is by FORM GST REG-32, with the withdrawal order in FORM GST REG-33.
