Why FilingPro?

Why Medavakkam Clients Choose FilingPro

Expert GST Registration in Medavakkam — qualified professionals, 15+ years experience, zero-penalty track record.

Constitution-Aware Form Drafting

Documentation requirements vary across proprietorships, partnerships, LLPs, private limited companies and HUFs. Each constitution has its specific Rule 8 implications, and the application is drafted to meet the precise documentary expectations applicable to that legal form.

Pre-Submission Document Review

Every annexure is reviewed against the applicable rule before submission. Address proof, signatory authorisation, photograph specifications and bank account proof are independently verified, removing the most common causes of REG-03 deficiency notices observed in our practice.

Aadhaar Authentication Walk-Through

Rule 8(4A) authentication is conducted with the signatory in real time over a coordinated session. The probability of failed OTP capture or session timeout, which would route the file to on-site inspection, is materially reduced by structured assistance.

Multi-State Filing Coordination

For applicants operating across States, parallel REG-01 filings are coordinated under one engagement. Constitution, signatory and bank account particulars are kept consistent across jurisdictions, preventing the cross-State data inconsistency that later requires REG-14 amendment.

Composition Eligibility Assessment

At the registration stage, Section 10 eligibility is evaluated against the applicant's projected turnover and supply mix. The flat-rate composition election is locked in where appropriate, since the alternative is to wait for the next financial year before opting in.

Verification Pathway Selection

The choice between Aadhaar authentication and physical verification is approached with reference to the applicant's capacity to complete biometric authentication and the documentary strength of the principal place of business. The pathway likely to yield faster approval is actively selected.

Key Benefits

What Medavakkam Clients Get

Every GST Registration engagement delivers measurable, guaranteed outcomes — expert professionals, on time, every time.

Clean First-Time Approval
Pre-submission REG-01 review eliminates the typical rejection causes — incomplete address proof, signatory mismatch, weak Aadhaar e-KYC. Medavakkam clients avoid the rework cycle of fresh applications.
Multi-State Consistency
Tamil Nadu plus other-State GSTINs of Medavakkam headquartered businesses share consistent constitution, signatory and PAN details — preventing cross-state inconsistency that triggers later amendments.
Composition Scheme Where Beneficial
Eligible Medavakkam traders below ₹1.5 crore turnover and service providers below ₹50 lakh under Section 10 are migrated to Composition at the registration stage — reducing compliance and tax.
Voluntary Registration Where Strategic
Below-threshold Medavakkam businesses opting for voluntary registration under Section 25(3) gain B2B credibility, ITC pass-through to corporate buyers and entry into e-commerce platforms.
REG-14 Amendment Support
Post-registration changes — trade name, additional places, bank account, signatory, partner addition or deletion — handled via REG-14 amendment under Rule 19 with the right core/non-core classification for Medavakkam clients.
Virtual Office Backed by NOC
Virtual office addresses come with valid lease, owner NOC and physical accessibility for Rule 25 verification — Madras HC and AAR-tested formats used by FilingPro.

How long does GST registration take after submitting REG-01?

Core documents are PAN of the business, Aadhaar of the authorised signatory and one promoter, recent photograph, proof of principal place of business (EB bill, property tax receipt or rent agreement plus NOC), bank account proof (cancelled cheque or passbook page) and DSC for companies/LLPs or EVC for other constitutions. Additional documents apply for partnerships and companies.
Can a residential address in Medavakkam be used for GST registration?
Yes. Residential premises can serve as principal place of business if supported by ownership proof (property tax or EB bill in the applicant's name) or a rent agreement with NOC from the owner. The address must be physically accessible for verification under Rule 25 and books of account must be maintained at this location under Section 35.
Is GST registration free or are there government fees?
There is no government fee for GST registration under the CGST Act or Rules. Submission of REG-01, REG-04 deficiency reply and REG-06 download are all free of cost on the GST portal.

What is the difference between regular GST registration and casual taxable person registration?

Regular registration is for ongoing operations from a fixed place of business; CTP registration under Section 27 is for occasional supplies in a State where the supplier has no fixed place, valid for 90 days extendable by 90, with advance tax deposit.

Can a freelancer register under GST?

Yes — a freelancer providing services can register voluntarily under Section 25(3) below the ₹20 lakh threshold or compulsorily above it. Registration is also required if making inter-State taxable supplies, regardless of turnover.

Do I need GST registration to sell on Amazon or Flipkart?

Yes — Section 24(ix) of the CGST Act makes GST registration compulsory for persons supplying through an e-commerce operator that is required to collect TCS, regardless of aggregate turnover.

What is compulsory registration under Section 24?

Section 24 of the CGST Act overrides the Section 22 threshold and mandates registration regardless of turnover for inter-State taxable suppliers, casual taxable persons, reverse-charge liable persons, e-commerce operators and sellers, NRTPs, TDS deductors, TCS collectors and ISDs.

How is aggregate turnover calculated for GST registration threshold?

Aggregate turnover under Section 2(6) is the all-India total of taxable supplies, exempt supplies, exports and inter-State supplies of a person having the same PAN, excluding inward supplies on reverse charge and central, State and Union Territory taxes.

Can a startup register for GST before commencement of business?

Yes — voluntary registration under Section 25(3) is available before commencement of business. Many startups register early to claim ITC on pre-commencement procurement and to enable B2B invoicing once operations begin.

A complete walkthrough — Gst Registration

Localised for Medavakkam, Chennai — where standalone retail and small-format stores operate just above the GST threshold often under the composition scheme.

Reading this guide locally — Medavakkam businesses operate where on the Velachery-Sholinganallur corridor that passes through Medavakkam, and Medavakkam businesses in the retail arm find that businesses face GST classification disputes cash-sales reconciliation and frequent Rule 138E e-way block alerts.

What is GST registration and when is it required

Statutory basis under Section 22

GST registration in India is governed by Sections 22 to 30 of the Central Goods and Services Tax Act 2017 read with corresponding State GST legislation. The trigger for compulsory registration under Section 22 is an aggregate annual turnover of ₹40 lakh for exclusive suppliers of goods in Tamil Nadu (per Notification 10/2019-Central Tax) and ₹20 lakh for service or mixed suppliers. Aggregate turnover under Section 2(6) is the sum of all taxable supplies, exempt supplies, exports of goods and services, and inter-State supplies of a person having the same Permanent Account Number, computed on an all-India basis. Once a person crosses this threshold in any financial year, the obligation to register arises within thirty days under Section 25(1). Section 24 of the CGST Act overrides Section 22 entirely for specified categories including inter-State taxable suppliers, casual taxable persons, persons supplying through e-commerce operators, and reverse-charge liable persons — these categories must register regardless of turnover.

Voluntary registration option

A person whose aggregate turnover is below the threshold can still register voluntarily under Section 25(3) of the CGST Act. Once voluntary registration is granted, all provisions of GST law apply to such a person as they would to any registered person — including monthly returns, ITC eligibility for inputs, and the obligation to issue tax invoices. Voluntary registration is commonly chosen by B2B service providers and traders who want to enable ITC pass-through to their corporate clients, by exporters who need to file LUTs and claim refunds, and by startups that want to capture ITC on early-stage procurement before revenue commencement. Once obtained, voluntary registration cannot be casually surrendered — REG-16 cancellation follows the same procedure as any other cancellation under Section 29.

Composition scheme versus regular registration

Eligibility under Section 10

The composition scheme under Section 10 of the CGST Act is an alternative simplified scheme for small taxpayers with aggregate turnover up to ₹1.5 crore (₹75 lakh for special-category States including Arunachal Pradesh, Manipur, Meghalaya, Mizoram, Nagaland, Sikkim, Tripura, and Uttarakhand). For service providers, a separate composition under Section 10(2A) is available up to ₹50 lakh aggregate turnover. The scheme is opted at the time of REG-01 application by marking the composition box; an already-registered regular taxpayer can opt in later by filing CMP-02 before the commencement of the financial year. Section 10(2) excludes from composition: persons making inter-State supplies, persons making supplies through e-commerce operators that collect TCS, manufacturers of notified goods (tobacco, pan masala, ice cream, aerated water), casual or non-resident taxable persons.

Composition rates

The flat tax rates under the composition scheme are: 1 percent of turnover for traders and manufacturers (0.5 percent CGST + 0.5 percent SGST), 5 percent for restaurants not serving alcohol (2.5 percent CGST + 2.5 percent SGST), and 6 percent for service providers under Section 10(2A) (3 percent CGST + 3 percent SGST). The composition taxpayer cannot collect tax from customers, cannot issue tax invoices (only bills of supply), and cannot claim ITC on inputs. Compliance is lighter: quarterly CMP-08 challan-cum-statement instead of monthly GSTR-3B, and annual GSTR-4 instead of GSTR-9. Composition is most attractive for B2C businesses with low value-added margins where the simpler compliance outweighs the loss of ITC.

Switching between schemes

A composition taxpayer who crosses the eligibility threshold or whose circumstances change can switch to regular registration mid-year by filing Form CMP-04 within seven days of the disqualifying event. Conversely, a regular taxpayer can opt in to composition only at the start of a financial year by filing CMP-02 before 31 March of the preceding year. The switch from regular to composition entails reversal of ITC balance in the electronic credit ledger as on the date of switch. The switch from composition to regular entails ITC claim on opening stock as on the date of switch, in Form ITC-01 within 30 days.

Special cases — multi-State branches business verticals SEZ

Separate State registration

Section 25(1) of the CGST Act requires every person making taxable supplies from a State to obtain a separate registration in that State. The principle is one registration per State per PAN, with sub-cases for multi-vertical entities. A business with a Tamil Nadu base expanding into Karnataka, Andhra Pradesh and Telangana needs four separate GSTINs — one in each State of operation — even though all four are under the same PAN. Each State registration files its own monthly returns, maintains its own electronic ledgers, and is independently subject to scrutiny by the respective State commissionerate. Inter-State stock transfer between own branches is treated as a supply under Schedule I and requires invoicing and e-way bills.

Multiple registrations within the same State

Section 25(2) read with Rule 11 of the CGST Rules permits a person to obtain more than one registration in the same State for distinct business verticals. A business vertical is defined in the rules as a distinguishable component of an entity engaged in supplying an individual product or service or a group of related products or services that is subject to risks and returns that are different from those of other business verticals. The classic example is a manufacturer with both an industrial-products arm and a consumer-products arm; another is a real-estate developer with both a residential project and a commercial project. Each vertical obtains its own GSTIN under the same PAN; ITC cannot be cross-utilised between verticals but the Input Service Distributor mechanism under Section 20 can be used for shared input services.

SEZ unit and developer registration

Special Economic Zone units and SEZ developers are required to obtain registration in the SEZ State separately from any registration the parent group may hold in the same State for non-SEZ operations. The SEZ-zone unit operates outside the customs territory of India and supplies into the SEZ from DTA suppliers are treated as zero-rated supplies under Section 16 of the IGST Act; supplies from SEZ to DTA are treated as inter-State supplies and attract IGST. SEZ units file the standard monthly GSTR-1 and GSTR-3B and apply for refunds of accumulated ITC under Section 54 with Rule 89 conditions. The SEZ-LoA (Letter of Approval) is captured as supporting documentation in REG-01.

Common registration mistakes and how to avoid them

Wrong PAN or constitution declaration

The most consequential REG-01 error is mismatch between the constitution declared in REG-01 and the legal constitution of the entity. A sole proprietor declaring constitution as Partnership invites rejection at REG-03 stage. A pre-incorporation company declared with its proposed name (without certificate of incorporation) is similarly rejected. Care must be taken to declare the exact constitution as on the date of REG-01 filing, with corresponding PAN and address proof aligned. For companies, the registered office address with MCA must match the principal place of business in REG-01 to the letter — any difference triggers Rule 9 deficiency notice. For partnerships, the partnership deed must be registered with the appropriate registrar where State law requires it (Tamil Nadu permits unregistered firms but registration is preferred for compliance robustness).

Address proof and NOC errors

Address proof errors are the second most common source of registration delay. The accepted address-proof documents are: latest electricity bill (not older than 60 days), property tax receipt, registered rent agreement (for rented premises), title deed (for owned premises), and consent letter / NOC from the owner along with the owner's address proof (for premises not in the applicant's name). A rent agreement on plain paper without registration is generally rejected for non-residential GST registration. The NOC from the owner must be on the owner's letterhead (for corporate owners) or on plain paper with notarisation (for individual owners). Where the property is jointly owned, NOC from all joint owners is preferred. Co-working space registration requires the operator's own rent agreement and electricity bill plus a notarised seat-allocation NOC.

HSN SAC and business activity declaration

REG-01 Part B requires declaration of the principal HSN code (for goods) or SAC code (for services) and up to four secondary HSN / SAC codes. Common mistakes include: declaring an HSN that does not match the actual business activity, using too generic a code (e.g. HSN 99 for services without sub-classification), or omitting a major business line entirely. Wrong HSN declaration at registration cascades into wrong rate disputes in subsequent returns and ITC questions on inputs. A short consultation with a tax practitioner to map the business activity to the correct HSN / SAC codes is well worth the time. For multi-vertical businesses, the HSN list should cover all verticals — Rule 19 amendment can add HSN codes later, but starting with the right list avoids subsequent compliance friction.

What Medavakkam clients usually ask next: For Medavakkam engagements specifically — where standalone retail and small-format stores operate just above the GST threshold often under the composition scheme; for the professional and salaried population of Medavakkam navigating personal-tax and home-office GST.

Glossary

Plain-English glossary for this service

Terms you will hear in this area — Medavakkam businesses operate where where standalone retail and small-format stores operate just above the GST threshold often under the composition scheme.

B2B Supply

Business-to-business supply where the recipient is a registered person. Invoice-level details are required to be declared in GSTR-1 to enable recipient ITC.

B2C Supply

Business-to-consumer supply where the recipient is unregistered or a final consumer. Aggregate-level details are declared in GSTR-1; HSN-summary still required.

Inter-State Supply

Supply where the location of supplier and the place of supply are in two different States. Attracts IGST. Triggers compulsory registration under Section 24(i) regardless of turnover.

Intra-State Supply

Supply where the location of supplier and the place of supply are in the same State. Attracts CGST plus SGST.

Bill to Ship to

Mode of supply where the buyer (bill-to) and recipient (ship-to) are different — e.g. direct delivery to buyer's customer. ITC entitlement is to the bill-to party per Section 16(2)(b) Explanation read with Press Release dated 23 April 2018.

e-Way Bill

Electronic waybill generated for movement of goods of value exceeding ₹50,000 (or lower in some States). Mandatory under Rule 138. Non-generation triggers detention and penalty under Section 129.

Letter of Undertaking

LUT — undertaking filed by an exporter to make exports of goods or services without payment of IGST. Filed in Form RFD-11 and valid for the financial year.

Special Economic Zone

SEZ — duty-free enclave deemed to be foreign territory for the purposes of trade operations and duties. Supplies to SEZ are zero-rated under Section 16 of the IGST Act.

Zero-Rated Supply

Supply of goods or services where the GST liability is zero but the supplier is entitled to claim ITC on inputs. Includes exports and supplies to SEZ. Section 16 of the IGST Act.

Mixed Supply

Two or more individual supplies of goods or services made for a single price, none of which are naturally bundled. Taxed at the rate of the supply that attracts the highest rate of tax.

Composite Supply

Two or more taxable supplies of goods or services naturally bundled and supplied in conjunction in the ordinary course of business, with one being the principal supply. Taxed at the rate applicable to the principal supply.

PMT-06

Challan for GST Payment: Form used to deposit tax, interest, penalty or any other amount under GST. Generated on the portal and paid via net-banking, NEFT/RTGS, OTC (limited cases), or credit card.

Cost of Non-Compliance

Real-world penalty exposure

Numerical examples showing tax + interest + penalty across common default scenarios.

Penalty exposure typical of this micro-market — Medavakkam businesses operate where Medavakkam businesses in the retail arm find that businesses face GST classification disputes cash-sales reconciliation and frequent Rule 138E e-way block alerts.

By Industry

Industry-specific patterns in Medavakkam

How the local trade mix shapes this — Medavakkam businesses operate where where standalone retail and small-format stores operate just above the GST threshold often under the composition scheme, and the cluster of residential, retail, healthcare businesses that defines Medavakkam's commercial fabric.

Healthcare
Common issue: Healthcare clinics and hospitals often miss the GST registration trigger that arises from the pharmacy arm sales to walk-ins. Healthcare services are exempt under Notification 12/2017-CT(R) but pharmacy supplies to non-patients are taxable.
How we handle it: Register on the basis of the pharmacy arm alone if its turnover crosses ₹40 lakh; declare exempt healthcare receipts under nil-rated head in GSTR-1; apportion ITC under Rule 42 between exempt and taxable arms.
Retail
Common issue: Family-run retail clusters where multiple units operate under the same PAN often miss the aggregate-turnover rule. Section 2(6) computes aggregate turnover PAN-wise across all branches and States; the threshold applies to the sum, not to each branch.
How we handle it: Compute aggregate turnover PAN-wise on a rolling 12-month basis; if combined turnover approaches the threshold, register one GSTIN covering all branches as principal and additional places, or opt for composition if eligibility holds.
Education
Common issue: Coaching institutes often misclassify educational services as exempt under Notification 12/2017-CT(R). Only educational services up to higher secondary (and notified vocational courses) are exempt; commercial coaching at any level above is taxable at 18%.
How we handle it: Register on the coaching turnover; declare any genuinely exempt arm (formal school, Section 12AA-approved educational supplies) under nil-rated head; ensure faculty TDS under Section 194J is captured in parallel.
Residential
Common issue: Personal-tax-only filers sometimes obtain GST registration unnecessarily when they start a side-gig that does not yet meet threshold. The overhead of monthly returns is then a sunk cost.
How we handle it: Don't register voluntarily unless the side-gig has crossed ₹20 lakh threshold or is making inter-State / e-commerce supplies; voluntary registration once obtained requires the same monthly compliance as any registered person.
Pharmaceuticals
Common issue: Pharma manufacturers face inverted-duty refunds under Rule 89(5) on API to formulation rate differential. Lost if registration is delayed since pre-registration inputs cannot be refunded.
How we handle it: Register early; set up monthly Rule 89(5) refund computation; reconcile API procurement against formulation outputs; file refund applications quarterly under Section 54.
Case Studies

Anonymised engagements we have handled

Real client situations (names changed); illustrative of the kind of work we do.

A flavour of cases we handle nearby — Medavakkam businesses operate where where standalone retail and small-format stores operate just above the GST threshold often under the composition scheme, and Medavakkam businesses in the retail arm find that businesses face GST classification disputes cash-sales reconciliation and frequent Rule 138E e-way block alerts.

ISD registrationIT Services

ISD registration for shared services arm

Issue: An IT-services group with three GSTINs across three States wanted to centralise procurement of shared services (audit fees, ERP-licence, marketing) at the Chennai head office and distribute the ITC through the ISD route under Section 20.
Approach: Filed REG-01 in the ISD category for the head-office PAN with the Chennai address; captured ISD-only role in the registration; set up monthly GSTR-6 filing to distribute the ITC across the three operating GSTINs based on Section 20 turnover ratios.
Outcome: ISD GSTIN granted within 7 working days; GSTR-6 filed monthly distributing ITC of approx ₹4 lakh per month across the three operating GSTINs; consolidated reconciliation reduced cross-State ITC accumulation friction.
Trust taxable armEducation

NGO registers for taxable receipts

Issue: An NGO providing free education also had a paid training-of-trainers programme that generated ₹35 lakh annually — a taxable supply since training services for a fee are outside the Section 12 exemption. The NGO needed GST registration for this taxable arm only.
Approach: Filed REG-01 with the trust's PAN; captured the office as principal place of business; declared the taxable supplies under coaching SAC; managed exempt-supply disclosure separately in GSTR-1 nil-rated head.
Outcome: GSTIN granted in 6 working days; monthly compliance set up; exempt supplies (free education) shown separately; ITC apportionment between exempt and taxable arms managed via Rule 42.
Regular schemeRestaurants

Restaurant cluster registers under regular scheme

Issue: A premium restaurant chain in Alwarpet with annual turnover of ₹2.4 crore could not opt for composition under Section 10 since composition for restaurants is capped at ₹1.5 crore turnover. They needed regular registration with the 5%-without-ITC option for the restaurant arm.
Approach: Filed REG-01 in regular category; selected the 5%-without-ITC option for the restaurant supplies; ensured ITC reversal mechanism aligned with the 5% scheme; the bakery arm (separate supply) optionally claimed at 18% with full ITC by separating into a vertical.
Outcome: GSTIN granted in 5 working days; first month GSTR-1 / GSTR-3B captured 5% restaurant supplies; ITC reversal on inputs (utilities, kitchen consumables) reconciled; clean Section 9(5) e-commerce TCS reconciliation with Zomato / Swiggy invoices.
DSC alternativeSmall Trade

DSC issue resolved via EVC route

Issue: A first-generation petty proprietor in Sowcarpet did not have access to a DSC and the cost / certification of obtaining one was a barrier. EVC route was used for proprietorship registrations.
Approach: Filed REG-01 with EVC verification via OTP to the proprietor's mobile and email; Aadhaar authentication smoothened identity verification; no DSC was required.
Outcome: GSTIN issued in 5 working days; subsequent return filings continued via EVC route; no DSC procurement cost incurred.

Why these Medavakkam engagements look the way they do: For Medavakkam engagements specifically — the cluster of residential, retail, healthcare businesses that defines Medavakkam's commercial fabric; for the professional and salaried population of Medavakkam navigating personal-tax and home-office GST.

Common Questions

GST Registration FAQ — Medavakkam

Common questions from Medavakkam clients. Call 9566-068-468 for specific queries.

ARN (Application Reference Number) is a 15-character alphanumeric tracking ID auto-generated by the GST portal once REG-01 is successfully submitted with verification (DSC, EVC or Aadhaar OTP). It is the basis for tracking the registration application status, downloading REG-02 acknowledgement, responding to REG-03 deficiency notices and ultimately receiving REG-06 the registration certificate.
An Input Service Distributor under Section 2(61) is an office of a supplier that receives tax invoices for input services and distributes the credit to other registrations of the same PAN. ISD registration is compulsory under Section 24 even if the head office is otherwise registered as a regular taxpayer. ISD files monthly GSTR-6 by the 13th detailing credit distribution.
Yes. The first discussion about your GST Registration requirement is free — call or WhatsApp 9566-068-468 and we will tell you honestly what is involved, what it costs, and the realistic timeline before you commit to anything.
Section 24 of the CGST Act mandates compulsory registration regardless of turnover for inter-state taxable suppliers, casual taxable persons, persons liable under reverse charge, e-commerce operators and sellers on e-commerce platforms, non-resident taxable persons, TDS deductors under Section 51, TCS collectors under Section 52, Input Service Distributors and persons supplying through electronic commerce operators required to collect TCS.
Form GST REG-29 was the form for voluntary cancellation by registrants who had migrated from VAT/Service Tax. The form is now largely subsumed; current voluntary cancellations are filed in Form REG-16 under Rule 20 citing reasons such as discontinuation of business, transfer/merger, change in constitution or turnover falling below the Section 22 threshold.
Yes — we work comfortably in both Tamil and English, which makes explaining GST Registration to Medavakkam clients straightforward. Ask your questions in whichever language you prefer, by call or WhatsApp on 9566-068-468.
Principal place of business is defined in Section 2(89) of the CGST Act as the place specified in the registration certificate from which the business is ordinarily carried on and where books of account and records are kept. It must be supported by ownership proof or a valid rent agreement with NOC; commercial, residential or shared premises are all acceptable provided documentary proof is in order.
Yes. Sub-section (3) of Section 25 expressly provides that all provisions of the Act, as are applicable to a registered person, shall apply to a voluntary registrant from the effective date of registration. Returns under Section 39, tax payment under Section 49, e-invoicing where Notification 10/2023 thresholds apply, e-way bill compliance and audit trail under Section 35 attach in identical measure. A voluntary GSTIN, once granted, may not be surrendered for twelve months from its effective date except on the limited grounds enumerated in Section 29(1). The strategic case for voluntary registration rests on input tax credit pass-through and B2B credibility, weighed against this compliance obligation.
Call or WhatsApp 9566-068-468 with a one-line description of your requirement. We confirm exactly which documents your Medavakkam case needs, share a fixed quote upfront, and start once you approve. The first discussion is free.
It is not strictly compulsory but opting out of Aadhaar authentication routes the file straight to physical verification under Rule 25, with the approval window stretching to 30 days from submission. Notification 62/2020 made authentication the practical default and most applicants take that route. The signatory and one promoter must complete OTP authentication, the OTP comes to the Aadhaar-linked mobile number, and if the linkage is stale the OTP simply does not arrive. We always confirm Aadhaar mobile linkage at intake, before the application is submitted, so we do not lose a day to a failed OTP. Where authentication is genuinely not feasible, the physical verification route is workable but slower.
On paper Rule 9 says seven working days from REG-01 submission for the deemed approval window, where Aadhaar authentication has gone through. In real-life data across our last 200-odd applications, the true average from submission to REG-06 download sits at about nine working days. The reason for the gap is small frictions — bank NPCI validation taking a day, the odd weekend falling in the window, occasional officer pull-outs for verification under Rule 25. If Aadhaar authentication is opted out or fails, the timeline extends to 30 days under the physical verification route. We commit nine working days to the client on day one so plans for invoicing align with reality.
Not sure whether GST Registration applies to you? Call 9566-068-468 and describe your situation — we will tell you plainly whether you need it, when, and what it involves, before you spend anything. Many Medavakkam enquiries start exactly this way.
The State-wise design under Section 25(1) of the CGST Act reflects the constitutional bargain captured in Article 246A and Article 279A, under which both the Union and the States retain concurrent authority to levy GST on intra-State supplies. A single national registration would have collapsed this dual sovereignty into a Union construct, undermining the fiscal-federal foundation of the regime. By contrast, the OECD International VAT Guidelines contemplate a single registration because most member jurisdictions are unitary. The Indian model accepts a higher administrative cost in exchange for preserving the consumption-tax claim of each destination State.
Operating without registration when liable attracts penalty under Section 122(1)(xi) of ₹10,000 or tax evaded whichever is higher, plus tax with interest under Section 50 at 18% per annum on supplies made in the unregistered period. The proper officer may also issue suo motu registration under Section 25(8) read with Rule 16 imposing the GSTIN from the date of liability.
Yes. Section 25(2) read with Rule 11 permits a person with multiple business verticals or separate places of business in the same State to obtain separate registrations for each, provided each is treated as a distinct person. Each GSTIN files independent returns and inter-vertical supplies are taxable transactions with tax invoices and IGST/CGST+SGST as applicable.
Rule 25 of the CGST Rules confines the scope of physical verification to confirming the existence and genuineness of the principal place of business. The proper officer is required to upload geo-tagged photographs and a verification report in Form REG-30 within fifteen working days of the visit. Adverse findings must be communicated to the applicant in REG-03 with an opportunity to respond in REG-04. A rejection in REG-05 founded on physical verification without affording such opportunity is liable to be set aside in appeal as it offends natural justice. Detailed contemporaneous documentation of the premises is the best defence.
