Quick Answer

What is REG-03 and how seriously should I treat it in Saidapet, Chennai?

REG-03 is the deficiency notice the jurisdictional officer issues under Rule 9 sub-rule 2 when something on the REG-01 file needs clarification or additional documentation. It must be replied to in Form REG-04 within seven working days. Missing the seven-day reply window leads to outright rejection through Form REG-05 and the application has to be re-filed from scratch. So we treat REG-03 as urgent. Internal turnaround in our office is forty-eight hours from receipt — partner reviews the memo, identifies the specific gap, the client provides the corrected document, and REG-04 is filed with point-by-point clarification. In our last 200 applications all eight that received memos cleared on the first REG-04 pass.

Why FilingPro?

Why Saidapet Clients Choose FilingPro

Expert GST Registration in Saidapet — 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 Saidapet Clients Get

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

REG-04 reply within forty-eight hours
When a REG-03 deficiency memo arrives, the seven-day reply clock is real. Our standard internal turnaround for drafting and filing REG-04 is forty-eight hours from receipt. In the last 200 odd applications, the eight that received deficiency memos all cleared on the first REG-04 pass.
Right scheme picked at registration
Composition under Section 10 versus regular is a strategic choice that constrains the year once made. We assess turnover trajectory, B2B versus B2C mix, and whether buyers need ITC pass-through, then advise. About one in five proprietorship clients with us starts on Composition.
Section 24 trigger screening at sign-up
Inter-state supply, e-commerce listing, RCM liability, casual presence and TCS collector status are checked at the very first intake call. If any apply, registration is compulsory regardless of turnover, and the 30-day Section 25(1) clock is logged in our follow-up system.
Multi-state expansion handled in parallel
When a client expands beyond Tamil Nadu, separate REG-01 filings for each State are coordinated under one engagement, with consistent constitution, signatory and PAN data. Inconsistencies between State GSTINs cause amendment headaches later, so we lock the master data on day one.
Bank validation pre-checked
NPCI validation of the bank account fails more often than people expect, usually because of a name-spelling mismatch between PAN and the bank. We pre-check the bank account in the proposed legal name before submitting REG-01, which removes one of the silent rejection causes.
REG-06 delivered with display formatting
The certificate is downloaded the day approval lands and shared on WhatsApp formatted as a Rule 18 display copy. A second copy is kept in our document vault under the client's PAN folder for audit reference, alongside the REG-01 acknowledgement and ARN history.

People Also Ask — GST Registration in Saidapet
Who is required to obtain GST registration in Tamil Nadu?
Every person whose aggregate annual turnover exceeds ₹40 lakh for goods or ₹20 lakh for services under Section 22 of the CGST Act must register. Additionally, Section 24 mandates registration irrespective of turnover for inter-state suppliers, e-commerce operators and sellers, casual taxable persons, persons liable under reverse charge, TDS/TCS deductors and Input Service Distributors.
How long does GST registration take after submitting REG-01?
With successful Aadhaar authentication, registration is deemed approved in 7 working days from REG-01 submission unless the proper officer issues a REG-03 deficiency notice. Without Aadhaar authentication, physical verification of the principal place of business under Rule 25 is mandatory and approval extends up to 30 days under Rule 9(5).
What documents are needed for GST registration in Saidapet?
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 Saidapet 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. Professional fees for REG-01 preparation, Aadhaar authentication assistance, ARN tracking and post-registration return preparation are charged separately by GST consultants.
What happens if GST registration application is rejected?
Rejection is communicated through Form REG-05 with reasons recorded. The applicant may file a fresh REG-01 addressing the rejection grounds with corrected documents. Alternatively, an appeal may be filed under Section 107 of the CGST Act before the Appellate Authority within 3 months of the rejection order, with pre-deposit conditions where applicable.
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.

What is the validity period of GST registration?

GST registration for regular taxable persons does not have a fixed validity — it continues till cancelled. Registration for casual taxable persons and non-resident taxable persons is valid for 90 days, extendable by 90 more under Section 27(2).

What happens after submitting REG-01 application?

After REG-01 submission an ARN is generated. The proper officer examines the application within 7 working days. If complete, REG-06 certificate is issued; if deficient, REG-03 notice for additional information is issued and the applicant has 7 working days to reply in REG-04.

What if my GST registration application is rejected?

A complete walkthrough — Gst Registration

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

Reading this guide locally — Saidapet businesses operate where around the Saidapet Court catchment of Saidapet, and Saidapet 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.

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.

After registration — first compliance milestones

Display of GSTIN at place of business

Section 26 of the CGST Rules read with Rule 18 requires every registered person to display the certificate of registration (REG-06) at a prominent location of every place of business — principal and all additional places. The GSTIN must also be displayed on the name-board outside each place of business. Non-display attracts a general penalty under Section 125 (₹25,000 each for CGST and SGST). Many small traders overlook this requirement; while it rarely leads to material penalty proceedings, departmental visits do flag it.

Invoice format and tax invoice rules

Once registered, the registered person must issue tax invoices for taxable supplies in the format prescribed under Rule 46 of the CGST Rules. The tax invoice must carry: invoice number (consecutive, unique for the FY), date of issue, supplier GSTIN and name, recipient GSTIN and name (for B2B), recipient address, HSN / SAC code, description of goods or services, quantity / unit (for goods), value of supply, taxable value after discount, applicable rate of GST, amount of CGST + SGST or IGST, place of supply (for inter-State), reverse-charge applicability (if any), and signature of the supplier or authorised representative. Composition taxpayers issue bills of supply (Rule 49) instead of tax invoices. Specific timelines apply for issuance — for goods, before or at the time of removal; for services, within 30 days of supply.

Setting up books of accounts under Rule 56

Rule 56 of the CGST Rules prescribes the books of accounts to be maintained by every registered person at the principal place of business and at every additional place. The records include: register of production / manufacture (for manufacturers), register of inward and outward supplies, register of stock, register of input tax credit availed, register of output tax payable and paid. Records must be retained for at least 72 months from the due date of furnishing the annual return for the year (effectively six years). Electronic record-keeping is permitted but a print-out or generation-on-demand capability is required. For jewellers, Rule 56(18) prescribes a stock register specific to high-value precious-metal supplies.

Cancellation and revocation pathway

Voluntary cancellation under Section 29(1)

Section 29(1) of the CGST Act and Rule 20 of the CGST Rules permit voluntary cancellation of GST registration in five scenarios: discontinuance of business, transfer of business including amalgamation or demerger, change in constitution of business resulting in a new PAN, taxable supply ceasing to be in the regime, or aggregate turnover falling below the threshold (other than Section 24 categories). The application is filed in Form REG-16 within 30 days of the event triggering cancellation. The proper officer examines the application and either grants cancellation in REG-19 or seeks information in REG-17. After cancellation, the final return GSTR-10 must be filed within three months of the cancellation order or the effective date of cancellation, whichever is later. GSTR-10 captures stock-in-hand and tax thereon as of the cancellation date.

Suo motu cancellation and revocation

Section 29(2) of the CGST Act empowers the proper officer to cancel registration suo motu in seven scenarios — including non-filing of returns for six consecutive months (three quarters for composition), violation of provisions of the Act or Rules, fraudulent registration, and material discrepancy in the registration data. Before suo motu cancellation, the officer issues a show-cause notice in REG-17, to which the taxpayer must reply in REG-18 within seven working days. If the reply is unsatisfactory or no reply is filed, the cancellation order issues in REG-19. The taxpayer can apply for revocation of suo motu cancellation in REG-21 within 90 days, extendable by 60 days each by the Joint Commissioner and the Commissioner (totalling 180 days maximum). All pending returns must be filed before revocation can be granted. Revocation is approved in REG-22 or rejected in REG-05 after a show-cause in REG-23.

By Industry

Industry-specific patterns in Saidapet

How the local trade mix shapes this — Saidapet businesses operate where where standalone retail and small-format stores operate just above the GST threshold often under the composition scheme, and the business activity radiating outward from Saidapet Court and nearby commercial pockets.

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.
Hospitality
Common issue: Hotel and restaurant chains with multiple outlets sometimes register only the largest outlet, expecting smaller units to remain under threshold. Aggregate turnover is PAN-wise; partial registration creates compliance inconsistency.
How we handle it: Register all outlets under a single GSTIN as principal and additional places of business; for restaurant arms, choose between 5%-without-ITC (regular) and composition (1% / 5% / 6%) basis aggregate turnover and inter-State supply position.
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.
Engineering
Common issue: Engineering job-work units claim under SAC 9988 but mis-classify the underlying input-output GST flow. Job-work value addition is subject to specific rate notifications and ITC-04 quarterly filing is mandatory.
How we handle it: Register and set up ITC-04 filings concurrently; track inputs received from principal manufacturer separately from own-stock; reconcile quarterly ITC-04 movements with GSTR-1 outward supplies.
Textile
Common issue: Textile manufacturers face inverted-duty refund opportunities under Rule 89(5) but lose them by not registering early. Once registered, refund under Rule 89(5) can be claimed prospectively from the registration date.
How we handle it: Register early in the FY to maximise the refund window; ensure HSN classification under 50-63 is accurate; reconcile inputs (yarn, dye, packing) against outputs to compute inverted-duty refund quantum.
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 — Saidapet businesses operate where where standalone retail and small-format stores operate just above the GST threshold often under the composition scheme, and Saidapet businesses in the retail arm find that businesses face GST classification disputes cash-sales reconciliation and frequent Rule 138E e-way block alerts.

E-commerce TCSRetail

E-commerce seller registration before listing

Issue: A homemaker in Anna Nagar started a small handicrafts business and wanted to list on Amazon and Flipkart. Section 24(ix) of the CGST Act requires compulsory GST registration for anyone supplying through an e-commerce operator that collects TCS, regardless of turnover.
Approach: Filed REG-01 for a sole proprietorship under the homemaker's PAN, captured the residential address as principal place of business with NOC from the property owner (the spouse), opted for regular registration (composition is not available for e-commerce sellers under Section 10(2)(e)).
Outcome: GSTIN granted within 5 working days; Amazon and Flipkart seller accounts activated; first month sales of ₹85,000 captured in GSTR-1 with B2C consolidation; TCS collected by the e-commerce operator reconciled in GSTR-2B.
Constitution changeRetail

Family business converts proprietorship to partnership

Issue: A family-run textile retail business in T Nagar wanted to convert from sole proprietorship to a four-partner partnership for succession planning. The old GSTIN was on the proprietor's PAN; the new partnership had a separate PAN.
Approach: Filed REG-16 voluntary cancellation of old GSTIN on the basis of transfer of business; simultaneously filed fresh REG-01 for the new partnership firm; ensured stock-in-hand was transferred under Section 18(3) with corresponding ITC transfer in ITC-02.
Outcome: Old GSTIN cancelled with effective date matching the partnership-deed date; new partnership GSTIN issued in 5 working days; ITC of ₹2.4 lakh transferred via ITC-02; GSTR-10 final return filed for the old GSTIN within three months.
Voluntary exitSmall Trade

Petty trader voluntarily exits via cancellation

Issue: A petty trader in Pulianthope had a GST registration from earlier optimism about scaling up but actual annual turnover stayed below ₹20 lakh. He wanted to exit the GST net to reduce monthly compliance burden.
Approach: Examined eligibility — turnover below threshold and no compulsory-registration triggers under Section 24. Filed REG-16 voluntary cancellation; cleared all pending returns; reversed ITC on closing stock under Section 29(5).
Outcome: REG-19 cancellation order issued; effective date as requested; GSTR-10 final return filed within three months; ITC reversal of ₹38,000 deposited via DRC-03; clean exit without follow-on liability.
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.

Why these Saidapet engagements look the way they do: On the ground in Saidapet, the cluster of government offices, retail, hospitality businesses that defines Saidapet's commercial fabric; for Saidapet businesses balancing growth ambitions with tight statutory compliance.

GST Registration FAQ — Saidapet

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

REG-03 is the deficiency notice the jurisdictional officer issues under Rule 9 sub-rule 2 when something on the REG-01 file needs clarification or additional documentation. It must be replied to in Form REG-04 within seven working days. Missing the seven-day reply window leads to outright rejection through Form REG-05 and the application has to be re-filed from scratch. So we treat REG-03 as urgent. Internal turnaround in our office is forty-eight hours from receipt — partner reviews the memo, identifies the specific gap, the client provides the corrected document, and REG-04 is filed with point-by-point clarification. In our last 200 applications all eight that received memos cleared on the first REG-04 pass.
Form GST REG-01 is the application for registration prescribed under Rule 8 of the CGST Rules. It has Part A (PAN, mobile, email validation generating TRN) and Part B with sections covering business details, promoters/partners, authorised signatory, principal place of business, additional places, goods and services with HSN/SAC, bank account, state-specific information and verification. Aadhaar authentication or physical verification follows submission.
Yes — we handle GST Registration for individuals and businesses across Saidapet (PIN 600015) and nearby Guindy. The work is done end-to-end by our own team, with documents collected online over WhatsApp or email and in-person meetings available at our Maduravoyal and Nerkundram offices. Call 9566-068-468 to begin.
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.
Yes. Multiple additional places of business within the same State or Union Territory are added under one GSTIN by listing them in REG-01 Part B Section 17 with separate address proof for each. Branches in other States require a separate GSTIN as registration is State-specific under Section 22(1). Each additional place must have independent address proof submitted.
Turnaround depends on the service and how quickly you share documents. Once we have a complete set, GST Registration for Saidapet clients moves without avoidable delay, and we keep you posted at each stage. We give a realistic timeline upfront rather than an optimistic one.
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.
The original Section 22 threshold of twenty lakh rupees applied uniformly. Notification 10/2019-Central Tax raised the limit to forty lakh rupees only for exclusive suppliers of goods, leaving services at the earlier floor. The policy rationale, recorded in the 32nd GST Council recommendation, was that small traders had borne a disproportionately high compliance burden inherited from the State VAT regimes, where similar threshold relief had existed. Service suppliers, by contrast, faced a harmonised national service tax framework before GST and did not require equivalent transitional relief. The bifurcation thus addresses asymmetric historical compliance experience rather than economic difference.
Yes. Beyond GST Registration, we cover GST, income tax, TDS, company and LLP registrations, digital signatures, audits and finance documentation — so Saidapet clients keep all their compliance under one roof. Ask us about anything on 9566-068-468.
If Aadhaar authentication fails or is not opted, the application is routed for physical verification under Rule 9 read with Rule 25. The proper officer or authorised representative visits the declared principal place of business, takes geo-tagged photographs, verifies documents and uploads a verification report in REG-30 within 15 working days. Approval timeline extends to 30 days from REG-01 submission.
No. The list of documents required for registration is governed by Rule 8 read with the schedule to Form REG-01. A demand for extraneous documents not contemplated by the rules in a REG-03 deficiency notice exceeds jurisdiction and may be resisted in the REG-04 reply with appropriate citation. Where the officer persists and rejects on that ground, the REG-05 order becomes vulnerable in appeal under Section 107 or in writ before the Madras High Court. The applicant should nevertheless place a reasoned representation on record before invoking the appellate remedy, to demonstrate that the procedural courtesy was extended.
Very likely yes — Saidapet has a government commercial and transport profile where residential and allied activity creates exactly the compliance needs GST Registration addresses. We see these requirements here often and handle them efficiently. If it does not apply to you, we will say so.
Form GST REG-05 is the order of rejection of registration application issued by the proper officer when REG-04 reply is unsatisfactory or not filed, when documents are forged, or when verification reveals the applicant does not exist at the declared premises. The applicant may file a fresh REG-01 addressing the rejection grounds; appeal under Section 107 is also available within 3 months.
There is no government fee for GST registration under the CGST Act or Rules. Submission of REG-01 on the portal is free of cost. Professional fees for documentation, REG-01 preparation, Aadhaar authentication assistance, REG-04 deficiency reply and REG-06 download are charged separately by GST consultants.
Form GST REG-02 is the system-generated acknowledgement issued immediately after REG-01 submission, confirming receipt of the application and bearing the ARN. It is downloadable from the portal and serves as proof of application pending issue of the GSTIN. Possession of REG-02 alone does not authorise the applicant to charge GST or claim ITC.
From the effective date on REG-06, output GST must be charged on every taxable supply, tax invoices in the prescribed format under Rule 46 must be issued, the GSTIN must be prominently displayed at every premises covered by Rule 18, and the signboard and letterhead updated. Returns kick in from the same month — GSTR-1 by the eleventh of the next month for outward supplies, GSTR-3B by the twentieth with payment of net tax after ITC, and GSTR-9 annual return by the thirty-first of December of the following year. If aggregate turnover crosses the e-invoicing notification threshold, IRP enrolment also becomes mandatory. We handle the first month of returns on Professional and Premium plans.
