How Long Does GST Registration Take in 2026?

GST registration takes 7 working days from the date of submission of the application in an ordinary case, under Rule 9(1). Two faster routes exist. Rule 9A grants registration within 3 working days where the common portal identifies the applicant on data analysis and risk parameters. Rule 14A grants registration within 3 working days where the applicant opts in. An application marked for physical verification of the place of business takes 30 days (calendar days, not working days, under the proviso to Rule 9(1)). Which period applies is decided when you file, not afterwards.

How many days it takes depends on which of the four routes below an application takes, and all four are part of the full registration procedure.

Rule 9A grants registration within 3 working days from the date of submission of the application, automatically, to applicants the common portal identifies on data analysis and risk parameters.

Rule 14A grants registration within 3 working days from the date of submission of the application to an applicant who opts in at item 4.1 of Form GST REG-01.

Rule 9(1) requires the proper officer to approve an ordinary Aadhaar-authenticated application within 7 working days from the date of submission of the application.

The proviso to Rule 9(1) allows 30 days from the date of submission of the application where the place of business is verified physically, calendar days, not working days.

How the working days are counted

"Working day" is not defined anywhere. Not in the CGST Act, not in the CGST Rules, not in the IGST Act, not in the UTGST Act, and not in the General Clauses Act, 1897. No CBIC circular, instruction, notification or GSTN advisory defines it. No court has decided the point for Rule 9. The Act comes no closer than section 2(27), which defines "common working days", being "such days in succession which are not declared as gazetted holidays by the Central Government or the concerned State or Union territory Government", and that defined term appears nowhere else in the Act. Section 2(27) is an orphan carried in from the Model GST Law and never used, so it does not govern Rule 9 of its own force. The formula excludes gazetted holidays and says nothing about Saturdays and Sundays.

Four things are settled.

1. The day you file does not count. Rule 9 runs "from the date of submission" and "from the date of the receipt". Section 9 of the General Clauses Act, 1897 excludes the first day of a period introduced by "from", so counting starts the next day. The 7 working days you get to answer a Form GST REG-03 notice run the same way.
2. The 30-day period is 30 calendar days, not 30 working days. The rule says "days". GSTN's own functionality note on the change made by Notification No. 94/2020-Central Tax distinguishes the two periods in terms: applications "deemed approved in 7 working days", and, where Aadhaar authentication fails or is declined, "deemed approved after 30 calendar days". On GSTN's own reading the thirty-day period is calendar days.
3. If the last day falls on a day the office is closed, section 10 of the General Clauses Act allows the act on the next open day. Section 10 is a saving, not a definition: it rescues the final day and does not convert a calendar-day period into a working-day one. Section 10 therefore bites the 30-day periods, not the working-day ones. If day 30 is a Sunday or a gazetted holiday, the officer's deadline, and the date deemed approval could arise, moves to the next working day.
4. Deemed approval is automatic. Under Rule 9(5), read with section 25(12) of the Act, the application "shall be deemed to have been approved" if the officer takes no action in the period. GSTN's own note says the application "will get deemed approved … if no action is taken": the portal applies the deeming itself and generates the GSTIN. You do not apply for it.

What is not settled is whether "working days" excludes Saturdays and Sundays as well as gazetted holidays, or only gazetted holidays. The Act, Rules, CBIC and GSTN materials, and the cited judicial decisions leave the question open. Count both ways and act on the earlier date. To decide when to chase the department, count generously: seven working days may stretch well past ten calendar days across a weekend and a festival, and silence on day eight is not a breach. To decide when your own reply is due, count tightly and file Form GST REG-04 well before the outer edge. To decide whether deemed approval has arisen, do not assume, and check the ARN status on the portal.

The GST portal's Holiday List, at Services > User Services, shows the Central Government's working and non-working days and each State's and Union territory's holidays. GSTN describes it as provisional and not final, and no rule gives it legal effect, so use it to plan and never to argue. The authoritative source remains the State Government's own holiday notification, and the Department of Personnel and Training's annual circular for Central jurisdiction.

No decision settles the point either. In State of Kerala v. M/s. West Bengal Lottery Stockists Syndicate Pvt. Ltd., the Kerala High Court had the deemed-registration plea before it on 19 July 2019 and expressly declined to decide it, saying it was "not burdened with the task of adjudicating in this appeal whether the first respondent is entitled to have the benefit of deemed registration". The case still carries one useful point: deemed approval turns on whether the officer took action, not on whether the applicant was told of it. Bandana Mahato v. State of West Bengal, Calcutta High Court, 17 November 2021, is persuasive only, a single judge on a Panchayat statute, but it turns on the conscious use of "working days" in some sub-sections and bare "days" in another, which transposes exactly onto Rule 9(5): sub-clauses (a) and (c) say "seven working days" and sub-clause (b) says "thirty days", in the same sub-rule. Sakhkkar Mills Mazdoor Sangh v. Gwalior Sugar Co. Ltd., Supreme Court, 22 February 1985, holds that "working days" takes its colour from the working of the entity concerned, which supports reading Rule 9's working days as the working days of the office of the jurisdictional proper officer. M/s Gokul Constructions v. Assessment Unit, Telangana High Court, 30 April 2024, treats a Sunday, a second Saturday and a gazetted festival holiday alike as non-working, but in a direct-tax context, so it lends colour rather than authority. No Supreme Court decision, and no decision of any High Court in a fiscal statute, defines "working days" against "days".

The GST registration clock starts on the deemed date of submission fixed by Rule 8(4A), not on the day the Application Reference Number (ARN) is generated. Rule 8(4A) sets that date as the earlier of two events: the date Aadhaar authentication is completed, or 15 days from submission of the application in Part B of Form GST REG-01. Every downstream period runs from that date: the 7 working days in Rule 9(1), the 30 calendar days in its proviso, the deemed-approval periods in Rule 9(5), and the 3 working days in Rule 9A and Rule 14A(4). What happens on day 15 is not the same for every applicant.

No period in the CGST Rules runs from the generation of the Application Reference Number (ARN). The ARN is the tracking number for an application already made, and the phrase "date of submission of the application" in Rule 9 means the deemed date fixed by Rule 8(4A). What the ARN does buy you is visibility, at Services > Registration > Track Application Status.

Rule 8(4A) measures the 15 days from "the submission of the application in Part B of FORM GST REG-01". GSTN's own Aadhaar-authentication FAQ measures the OTP branch from "the generation of the TRN" and the biometric branch from submission of Part B. Both are reproduced above because both are official; the rule text governs where they diverge.

On the plain-OTP branch the two measurement points can differ by days: Rule 8(4A) counts from submission of Part B, GSTN's FAQ counts from generation of the TRN, and as a matter of prudence rather than of law an applicant should work from whichever of the two falls earlier. Which branch you are on, and what e-KYC or biometric verification involves, decides which clock, if any, then runs.

If you are risk-flagged into biometric verification, or you declined Aadhaar authentication, missing the 15-day window means no ARN is generated at all. The application is treated as never submitted and must be started again. The 15-day deemed-submission rule in Rule 8(4A) rescues only the plain-OTP Aadhaar applicant.

No, three different 15-day periods run during a GST registration, and only one of them fixes the deemed date of submission. Rule 8(4A)'s 15 days fixes the deemed date of submission of the application. The Temporary Reference Number (TRN) has its own 15-day validity, after which the TRN and everything saved against it are purged from the portal. The Aadhaar authentication link sent to the Promoter/Partner and the Primary Authorised Signatory is separately valid for 15 days and can be resent. Confusing the first with the second is the commonest reason a reader believes the approval clock has started when it has not.

Notification No. 18/2025-Central Tax dated 31 October 2025 created two separate 3-working-day routes, and they are not the same route. Rule 9A is automatic: the common portal grants registration within 3 working days where it identifies the applicant on data analysis and risk parameters, with no cap, nothing to opt into and nothing to withdraw from. Rule 14A is opt-in: the applicant elects it at item 4.1 of Part B of Form GST REG-01, carries a cap of ₹2,50,000 per month of output tax on supplies made to registered persons including compensation cess, must complete Aadhaar authentication under Rule 14A(2), and exits by Form GST REG-32. Both came into force on 1 November 2025.

That ₹2,50,000 is a monthly cap on output tax on supplies made to registered persons, including compensation cess, which makes it a tax figure and not a turnover figure.

Rule 9A and Rule 14A both grant registration within 3 working days from the date of submission of the application. The full attribute-by-attribute comparison, covering the trigger, the applications covered, the cap, Aadhaar authentication, the second-registration bar and the exit route, is set out at the ₹2.5 lakh cap.

A query in Form GST REG-03 extends the timeline in three legs, not two. The proper officer must issue the notice within 7 working days from the date of submission of the application, or not later than 30 calendar days where the physical-verification proviso applies. The applicant then has 7 working days from receipt of the notice to reply in Form GST REG-04. The officer must act on that reply within a further 7 working days. If the officer does not act within any of those periods, registration is deemed granted under Rule 9(5) and no application for it is needed.

Leg 1, the notice. The proper officer issues Form GST REG-03 within 7 working days from the date of submission of the application under Rule 9(2), or not later than 30 calendar days from that date under the proviso to Rule 9(2), where clause (a), (aa) or (b) of that proviso applies.Leg 2, the reply. The applicant furnishes the clarification, information or documents in Form GST REG-04 within 7 working days from the date of receipt of the notice, under Rule 9(2).Leg 3, the decision. The proper officer approves the grant of registration within 7 working days from the date of receipt of the clarification in Form GST REG-04, under Rule 9(3).

The reply window is seven working days from receipt, and missing it turns a query into a rejection. Where the officer is not satisfied with the clarification, the application is rejected by order in Form GST REG-05 under Rule 9(4). No rule prescribes a single outer figure for the whole sequence.

Every person liable to register must apply within 30 days from the date on which the liability to register arises, under section 25(1) of the CGST Act, 2017. That 30-day deadline is a filing obligation and is not the processing period in Rule 9. A casual taxable person and a non-resident taxable person must apply at least 5 days before commencing business, under the first proviso to section 25(1). Filing within the 30 days also fixes the effective date: registration then takes effect from the date the liability arose, and a late application takes effect only from the date registration is granted.

What that shift in the effective date costs you in input tax credit is a separate question, and no figure for it is stated here. Section 25(1), CGST Act 2017, and the rules that run from it are set out in full at what the Act and the Rules actually say.

Four things push a GST registration past 7 working days, and three of them are fixed by the rules rather than by the officer. Incomplete Aadhaar authentication moves the deemed date of submission to day 15 and routes the application to the 30-calendar-day physical-verification track. A flag on data analysis and risk parameters routes the application to biometric verification at a Facilitation Centre before the application is even complete. A notice in Form GST REG-03 adds the applicant's 7 working days to reply and the officer's further 7 working days to decide. A defective place-of-business proof is what most often triggers the second and third of these.

CBIC Instruction No. 03/2025-GST dated 17 April 2025 sets the processing discipline officers are meant to work to.

• Officers may seek only the documents listed in Form GST REG-01, and not the lessor's PAN or Aadhaar or extraneous photographs.
• Queries may be raised only with the approval of the Deputy or Assistant Commissioner, and discretionary physical verification needs an officer not below Assistant Commissioner (para 8(iii)(c)).
• Non-risky applications are to be approved within 7 working days.
• Flagged applications are to be approved within 30 calendar days after physical verification, with the report in Form GST REG-30 carrying GPS-tagged site photographs.

Rule 25(2) runs its five working days backwards from the deadline, not from the visit. The verification report in Form GST REG-30 is uploaded "at least five working days prior to the completion of the time period specified in the said proviso", which is five working days before the 30-calendar-day deadline in the proviso to Rule 9(1). Rule 25(1) is the forward-running rule: where verification is made after registration is granted, the report goes up within fifteen working days following the date of that verification.

Notification No. 38/2023-Central Tax dated 4 August 2023 removed the requirement that verification be carried out in the applicant's presence.

The risk parameters that route an application to biometric or physical verification are not published by CBIC or GSTN, so no page, agent or CA can promise a route in advance.

Where a period passes with no action, CBIC Instruction No. 04/2025-GST dated 2 May 2025 requires each CGST Zone to publicise a grievance email address for applicants whose ARN falls under Central jurisdiction, and the applicant submits the ARN, the jurisdiction and a description of the issue. Delhi Zone publishes grievance.cgstdelhi@gov.in under its Trade Notice No. 01/2025. An applicant under State jurisdiction has no equivalent registration grievance cell in Delhi and is routed instead to the GST Facilitation Centre and to CPGRAMS.
