The application is free and takes twenty minutes to key in. What decides the outcome in Mumbai is almost never the law. It is the address. This city runs on shared desks in Andheri, virtual offices in Lower Parel and businesses operating out of society flats in the suburbs, and every one of those raises the probability that an officer will come and look.
| Question | Short answer for Mumbai |
|---|---|
| Who registers you | Either the Maharashtra GST Department, whose entire Mumbai operation runs from GST Bhavan at Mazgaon, or the Central GST Mumbai Zone at Churchgate. The portal decides which. |
| State code on your GSTIN | 27. Every Mumbai GSTIN begins with 27, followed by your PAN. |
| Threshold | INR 40 lakh aggregate turnover for a goods-only supplier, INR 20 lakh for services. Maharashtra is a normal category state. |
| Government fee | Nil. GST law prescribes no fee for a registration application. |
| Aadhaar step | Mumbai applicants may be routed to a GST Suvidha Kendra for biometric Aadhaar authentication instead of OTP. Live across Maharashtra since 8 February 2025. |
| Approval time | 3 working days under Rule 9A if the system scores you low risk. Longer if flagged for physical verification. |
| The Mumbai-specific risk | Premises. Virtual offices, shared desks and society flats draw physical verification far more often here than anywhere else in the state. |
The application is free and takes twenty minutes to key in. What decides the outcome in Mumbai is almost never the law. It is the address.
This city runs on shared desks in Andheri, virtual offices in Lower Parel, registered offices at a CA's premises, and businesses operating out of society flats in the suburbs. Every one of those is legitimate. Every one of them also raises the probability that an officer will come and look, and if what he finds does not match what you filed, you start again.
We file your REG-01, map your pincode to the correct nodal division, tell you honestly whether your premises will attract a visit, and if the portal routes you to biometric verification we tell you which GST Suvidha Kendra to attend and what originals to carry. GST registration is free with any CorporateWalla package.
Maharashtra is a normal category state, so the higher thresholds apply. A goods-only supplier registers once aggregate turnover crosses INR 40 lakh in the financial year. A service provider registers at INR 20 lakh. A mixed supplier is generally judged on the INR 20 lakh services limit.
Aggregate turnover is computed across the whole PAN, not per branch and not per GSTIN, and it includes taxable supplies, exempt supplies, exports and inter-state supplies. That catches Mumbai consultancies and agencies with clients across states more often than they expect.
Voluntary registration is worth considering well below the threshold if your customers are registered businesses. In Mumbai's agency, media and B2B services market, corporate buyers routinely decline unregistered vendors because they cannot claim input tax credit on the invoice.
This surprises people, so it is worth stating plainly. The Maharashtra GST Department divides Mumbai into zones and nodal divisions named after suburbs, and almost all of them are physically housed at GST Bhavan, Mazgaon, Mumbai 400010.
Nodal Division 07 is called Andheri. Nodal Division 08 is Goregaon, 09 is Kandivali, 10 is Borivali, 11 is Ghatkopar, 12 is Sakinaka, 13 is Mulund, 14 is Chembur. Their published office address is the same Mazgaon building, spread across the old and new wings. Nariman Point is Nodal Division 02, Mazgaon itself is 04, Bandra 05, Santacruz 06.
Above the nodal divisions sit the zones: Mumbai South-East, Mumbai North-West, Mumbai South-West, Mumbai North and Mumbai North-East, each with its own audit division. Your allocation comes from the pincode of your principal place of business, which is why getting that field right on REG-01 matters more than most people realise. It determines who scrutinises your first return and who you answer if a notice arrives.
The practical consequence: do not go looking for a Kandivali GST office in Kandivali. If you are ever called in, you are going to Mazgaon.
The Central GST Mumbai Zone is headed by a Principal Chief Commissioner at GST Bhavan, 115 Maharishi Karve Marg, Churchgate, Mumbai 400020.
Its executive commissionerates are Mumbai Central, Mumbai East, Mumbai South, Mumbai West, Thane, Thane Rural, Palghar, Bhiwandi, Belapur, Navi Mumbai and Raigad. Alongside them sit Audit-I, Audit-II, Audit-III, Audit-Raigad and Audit-Thane, and the Appeals Commissionerates I, II, III, Raigad and Thane.
That list is the point. A business that calls itself a Mumbai business but operates from Thane, Vashi, Belapur, Bhiwandi or Panvel is not under a Mumbai commissionerate at all. It falls to Thane, Navi Mumbai, Belapur or Raigad. If you are choosing between a Mumbai address and a Navi Mumbai one, you are also choosing a different administering office, a different audit commissionerate and a different appellate forum.
Since 8 February 2025, Maharashtra applicants sit inside the biometric Aadhaar regime. GSTN rolled the functionality out for Maharashtra and Lakshadweep on that date, and the Commissioner of State Tax, Maharashtra notified the facilitation centres by notification dated 6 February 2025 under the proviso to sub-rule (4A) of Rule 8 of the Maharashtra GST Rules, 2017.
After you submit REG-01 the portal emails one of two links. Either OTP-based Aadhaar authentication, the familiar route, or an appointment link for a designated GST Suvidha Kendra. Which one you get is decided by data analysis and risk parameters, not by turnover or entity type.
If you are routed to a GSK, your ARN is not generated until the visit is done. Every promoter, partner and the primary authorised signatory named in the application has to attend in person, carrying the appointment confirmation, the jurisdiction details from the intimation email, original Aadhaar and PAN, and originals of every document uploaded. A photograph is taken and fingerprints are scanned.
Two failures dominate. Missing the appointment window, which means starting over. And an Aadhaar demographic mismatch, where a name, date of birth or gender differs between Aadhaar and PAN and the authentication fails at the counter. Fix Aadhaar before you file, not after.
| Category | What is needed |
|---|---|
| Identity | PAN of the business or proprietor. PAN and Aadhaar of every promoter, partner or director. Aadhaar of the primary authorised signatory. Passport photographs. |
| Constitution | Certificate of incorporation with MOA and AOA for a company. LLP agreement and incorporation certificate for an LLP. Partnership deed for a firm. Nothing extra for a proprietorship. |
| Owned premises | Latest property tax receipt or the sale deed, plus an electricity bill not older than two months. |
| Rented premises | Registered leave and licence agreement, a no objection certificate from the licensor, and a utility bill in the licensor's name. Registration of the agreement is standard practice in Mumbai and an unregistered one draws a query. |
| Coworking or shared desk | Consent letter from the operator, their ownership or tenancy proof, and a utility bill. Expect physical verification. |
| Virtual office | Same documents, higher scrutiny. Read the caution below before committing to one. |
| Banking | Cancelled cheque, passbook first page, or a bank statement showing account holder name, IFSC and account number. You may file without this and add it later. |
| Authorisation | Board resolution or letter of authorisation naming the authorised signatory, with a Class 3 DSC for companies and LLPs. |
On virtual offices, an honest word. They are legal, they are widely used in Mumbai, and marketplace sellers in particular rely on them to hold registrations across states. They are also the single most common reason a Mumbai application ends in physical verification or rejection. If the officer visits an address where nobody has heard of your business and no signage exists, your documents will not save the application.
If you use one, insist on a provider who will host an actual desk, display your signage, accept your post and be present when an officer calls. If they will not do those four things, you are buying an address, not a place of business, and the department has become good at telling the difference.
On society flats, check your cooperative housing society's bye-laws before you file. Many Mumbai societies prohibit commercial use, and an officer who visits a purely residential set-up can raise a query even where your paperwork is faultless.
Notification No. 18/2025 - Central Tax also inserted Rule 14A with effect from 1 November 2025. It offers an optional simplified electronic registration where estimated monthly output tax liability does not exceed INR 2.5 lakh, with Aadhaar authentication mandatory for the applicant and the authorised signatory, and registration granted electronically within three working days.
It suits a small Mumbai trader or a single-location service business that wants to be registered quickly and will stay under that ceiling. It is a poor fit for anything growing, because coming out of it is a separate process. Withdrawal is by FORM GST REG-32, subject to having filed the minimum required returns, and the officer disposes of it in FORM GST REG-33.
Our default advice to a scaling Mumbai business is the ordinary route under Rule 9A. Same three working days if your risk score is clean, without a ceiling to manage later.
| Route | Realistic timeline |
|---|---|
| Rule 9A, low risk, OTP Aadhaar authentication | 3 working days from submission |
| Rule 14A simplified scheme, Aadhaar authenticated | 3 working days from submission |
| Routed to a GST Suvidha Kendra for biometric verification | 3 working days after the visit, plus however long the appointment slot takes |
| Query raised in REG-03 | Add 7 to 15 working days from the date you file REG-04 |
| Physical verification of premises ordered | Add 15 to 30 days, and expect an officer at the address |
In Mumbai the binding constraint is usually the premises documentation, not the department. A clean registered leave and licence agreement with a matching utility bill is the difference between three days and three weeks.
| Component | Amount | Paid to |
|---|---|---|
| Government fee for the registration application | Nil | Not applicable, GST law charges nothing for REG-01 |
| CorporateWalla professional fee | Free with any CorporateWalla package | CorporateWalla |
| Class 3 DSC, where the entity is a company or LLP | From INR 499 | Certifying authority, through us |
| Biometric visit at a GST Suvidha Kendra, if you are routed there | No government charge, your own travel and time | Not applicable |
Every professional fee above excludes GST. Government charges, where any arise, are paid by you at actuals and none of it sits inside our fee.

Same city: GST Return Filing in Mumbai. Sibling city page: GST Registration in Pune. Maharashtra registrations that usually follow a GSTIN: PTEC and PTRC registration, and a Gumasta licence where you hold a physical establishment in Mumbai, Navi Mumbai or Thane. If your group holds registrations in more than one state, ISD registration became mandatory on 1 April 2025.
No. GST law prescribes no fee for filing FORM GST REG-01, in Mumbai or anywhere else in India. Anything you pay is a professional fee for preparing and filing the application. With CorporateWalla, GST registration is free with any package.
Either the Maharashtra GST Department or the Central GST Mumbai Zone, decided by the system and printed on your REG-06 certificate. On the state side, Mumbai's nodal divisions are named after suburbs but almost all of them operate physically from GST Bhavan, Mazgaon, Mumbai 400010. On the central side, the Principal Chief Commissioner sits at GST Bhavan, 115 Maharishi Karve Marg, Churchgate, Mumbai 400020.
No. The nodal divisions carry suburb names, but Nodal Division 09 (Kandivali), 07 (Andheri), 08 (Goregaon), 10 (Borivali), 11 (Ghatkopar), 12 (Sakinaka), 13 (Mulund) and 14 (Chembur) all publish the same address at GST Bhavan, Mazgaon. If you are called in, that is where you go.
Not on the central side. The CGST Mumbai Zone covers eleven commissionerates including Thane, Thane Rural, Navi Mumbai, Belapur, Bhiwandi, Palghar and Raigad, and each is a distinct administering office with its own audit and appellate commissionerates. So a Vashi or Thane address puts you under a different commissionerate from a Lower Parel one, with a different appellate forum if a dispute ever arises.
Legally yes, and many marketplace sellers do exactly this. Practically it is the highest-risk address type in the city. You will need a consent letter, the operator's ownership or tenancy proof and a utility bill, and you should expect physical verification. If an officer visits and finds no desk, no signage and nobody who knows your business, the documents will not save the application. Use a provider who will host a real desk, display your signage, accept post and be present for an officer visit.
Possibly. Since 8 February 2025, Maharashtra applicants may be routed to biometric Aadhaar authentication at a designated GST Suvidha Kendra instead of OTP. The portal decides this on data analysis and risk parameters after you submit REG-01. If you are routed there, every promoter and the authorised signatory must attend in person with original Aadhaar, PAN and the originals of everything uploaded. Your ARN is not generated until that is done.
INR 40 lakh of aggregate turnover for a business supplying goods only, and INR 20 lakh for a service provider, because Maharashtra is a normal category state. Aggregate turnover is computed across your entire PAN and includes exempt supplies, exports and inter-state supplies.
Three working days from submission if the portal scores your application low risk, under Rule 9A which took effect on 1 November 2025. If you are routed to a GST Suvidha Kendra the clock effectively starts after the biometric visit. If a query or physical verification is raised, add two to four weeks.
Yes, from your first sale. Suppliers selling through an e-commerce operator get no threshold relief. You will also need to add any marketplace fulfilment centre address to your registration as an additional place of business by a REG-14 amendment before that centre will accept your stock.
Only if your estimated monthly output tax liability will stay under INR 2.5 lakh. It gives the same three working day approval, but leaving it later means filing FORM GST REG-32 and waiting for disposal in FORM GST REG-33. A business that expects to grow past that ceiling is better off on the ordinary route.
