GST Registration

How should a multi-state business structure its GST registrations?

Multi-State & Virtual Office GST Structuring starts by mapping where supplies are made from, where stock is stored and which establishments operate in each State or Union Territory. A customer in another State does not by itself require registration there. Assess the statutory thresholds, compulsory-registration rules and exemptions for each business model before creating extra registrations. Document the reasoning so the registration footprint follows real operations rather than marketing addresses.

Can a shared or virtual office be used as the GST business address?

A shared office is not automatically disallowed, but a mailbox contract alone does not establish a genuine place of business. Confirm the right to occupy or use the premises, the landlord or provider's authority, access for verification and the business activity carried on there. Keep the applicable rent or lease agreement or consent letter, ownership evidence and supporting identity records consistent with the registration application. CBIC Instruction 03/2025-GST addresses documentary requirements, including shared and consent premises; it does not guarantee approval of every virtual-office package.

How are warehouses and additional places of business handled?

List the premises relevant to the actual supply chain. Within a State, review whether a warehouse belongs under an existing GSTIN as an additional place of business or whether the conditions for separate registration apply. Stock held and supplied from another State requires its own location-specific analysis. Align invoices, e-way bills, dispatch addresses and inventory records with the registrations; a customer billing address is not evidence of a supplier's establishment.

What changes when a business has more than one GSTIN?

Different GST registrations under the same PAN are treated as distinct persons for relevant GST purposes. Review inter-branch supplies, stock transfers, valuation, invoicing and input-tax-credit allocation instead of treating transfers as automatically tax-free internal movements. Identify common input services and assess the applicable ISD and cross-charge requirements. Keep State-wise reconciliations between the ledger, returns and inventory; more GSTINs create more compliance work, not an automatic tax saving.

What should be checked before signing a virtual-office contract?

Ask whether the provider can produce the premises documents needed for the application, allows actual access, accepts official communications and supports verification. Check that the address, unit number, owner consent and contractual user name agree. Decide who monitors notices and when address amendments will be filed after a move. Do not use fabricated rent agreements, borrowed utility bills or an address at which the business cannot demonstrate a lawful presence.

What is GST registration? GST registration thresholds depend on the State/UT, goods or services supplied and applicable notifications; section 24 compulsory-registration provisions must be read with exemptions. Registration provides a 15-digit GSTIN required for collecting tax, claiming Input Tax Credit, and filing returns. Virtual Auditor handles the complete GST registration process with ongoing compliance support — return filing, ITC optimisation, and appeal representation if needed. Quick Answer: GST Registration — GST registration online by CA firm. Regular, non-resident (foreigner), temporary, composition scheme. Expert filing with post-registration compliance. Timing depends on scrutiny and verification under Rule 9.

Types of GST Registration

Regular Registration (Section 22) Non-Resident (Section 24(v)) Temporary Registration Composition Scheme (Section 10) Input Service Distributor (ISD) Casual Taxable Person E-Commerce Operator (Section 24(ix)) TDS/TCS Registration SEZ Developer/Unit Voluntary Registration (Section 25(3))

When Is GST Registration Mandatory?

Regulatory basis: Sections 22-24, CGST Act 2017. Registration within 30 days of becoming liable. Voluntary registration available under Section 25(3) regardless of turnover.

GST registration depends on aggregate turnover, the State/UT, the type of supply and compulsory-registration provisions read with exemptions. Interstate services can qualify for Notification 10/2017–Integrated Tax. Below-threshold goods sellers through a TCS e-commerce operator can qualify under Notification 34/2023–Central Tax, subject to no interstate supplies, supply in only one State/UT, PAN and portal enrolment. Services through an operator require a separate check under Notification 65/2017–Central Tax, including its section 9(5) exclusion. A seller exemption is not an exemption for the operator.

Threshold-based registration: Aggregate turnover exceeding ₹40 lakhs (goods) or ₹20 lakhs (services) in a financial year. ₹10 lakhs for special category states (Manipur, Mizoram, Nagaland, Tripura).

Documents Required

PAN of business entity, Aadhaar of proprietor/partners/directors, photograph, proof of the principal place of business (one ownership document, or the rent agreement with one ownership document of the lessor, or a consent letter with the consenter's identity proof and ownership document — CBIC Instruction 03/2025-GST), bank statement or cancelled cheque, electricity bill of premises, and constitution documents (partnership deed, MOA/AOA for companies, LLP agreement).

Why Register Through a CA Firm vs. Self-Filing

You can file GST registration yourself on the GST portal. So why pay a CA firm?

1. Application rejection prevention: 15-20% of self-filed applications face queries or rejection due to incorrect HSN/SAC classification, incomplete address proof, or document format issues. Our CA team knows the exact requirements and formats that each state GST office expects — avoiding the rejection-refile-rejection cycle.

2. Post-registration compliance: Registration is day one of an ongoing compliance obligation. Monthly/quarterly returns (GSTR-1, GSTR-3B), annual return (GSTR-9), ITC reconciliation (GSTR-2A/2B matching), e-invoicing (if applicable), and e-way bills. Miss a deadline: ₹50-200/day penalty. We set up the compliance calendar from day one.

3. Future-proofing: Many businesses register under the wrong category or wrong state, creating complications when they expand. We advise on: regular vs. composition scheme, single vs. multi-state registration, ISD requirements, and whether voluntary registration makes sense for ITC recovery.

4. GST appeal readiness: If the department issues a demand, the same team that handled your registration — understanding your business model, transaction patterns, and compliance history — handles the appeal. No re-explaining your business to a new professional.

GST Registration for E-Commerce Sellers

E-commerce sellers face unique GST requirements under Section 24(ix):

GST registration depends on aggregate turnover, the State/UT, the type of supply and compulsory-registration provisions read with exemptions. Interstate services can qualify for Notification 10/2017–Integrated Tax. Below-threshold goods sellers through a TCS e-commerce operator can qualify under Notification 34/2023–Central Tax, subject to no interstate supplies, supply in only one State/UT, PAN and portal enrolment. Services through an operator require a separate check under Notification 65/2017–Central Tax, including its section 9(5) exclusion. A seller exemption is not an exemption for the operator.

TCS compliance: Section 52 applies to the net value of taxable supplies covered by the operator's collection obligation. Notification 15/2024–Central Tax reduced the central component to 0.25% from 10 July 2024. Check the matching State/UT or integrated-tax notification before calculating the total for a transaction; the central component alone is not the combined rate. Reconcile operator statements with the electronic cash ledger.

Multi-state complications: If you sell across states through e-commerce, you may need registration in each state where you have a physical presence (warehouse, fulfilment centre). From 1 November 2026, new rule 14B (Notification No. 05/2026-Central Tax (26 October 2026, CGST (Amendment) Rules, 2026)) lets a seller already registered in one State take a registration in another State on the same PAN without a place of business of its own there, by declaring the e-commerce operator's warehouse as the principal place of business, subject to the conditions in the rule. Even FBA (Fulfilled by Amazon) creates presence in states where Amazon warehouses hold your inventory.

We advise on: single vs. multi-state registration strategy, TCS reconciliation, input credit optimisation for e-commerce sellers, and compliance structuring to minimise multi-state burden.

Composition Scheme — Simplified Compliance

The Composition Scheme under Section 10 offers simplified compliance for small taxpayers:

Composition eligibility requires checking the applicable turnover limit, State/UT, goods or service activity and section 10 restrictions. Do not treat all supplies through an e-commerce operator as automatically excluded; goods and services have different conditions. Confirm eligibility before opting in.

Tax rates: Manufacturers: 1% of turnover. Traders: 1%. Restaurants: 5%. Service providers: 6%. These are flat rates — no input tax credit available.

Compliance: Composition taxpayers furnish quarterly CMP-08 statements and annual GSTR-4. Composition status is not by itself an exemption from e-way bill requirements; check the movement, value and applicable Rule 138 exemptions separately.

Trade-off: Simpler compliance but no ITC means higher effective tax cost. Suitable for businesses with low input costs (services, retail) where ITC benefit is minimal. Not suitable for businesses with high input costs (manufacturing with raw material purchases) where ITC loss outweighs compliance savings.

We advise on: composition vs. regular registration economics, threshold monitoring (mandatory conversion to regular if turnover crosses ₹1.5 crore), and transition filing requirements.

GST Registration for Non-Residents and Foreigners

Non-resident taxable persons and foreigners can register under GST (Section 24(v)) with specific requirements:

Application: Filed at least 5 days before commencing business in India. Registration valid for the period specified (minimum 1 day, maximum 90 days, extendable).

Advance tax deposit: Equal to the estimated tax liability for the registration period. Deposited at the time of application.

Authorised signatory: Must appoint an authorised person in India as a signatory for GST filings.

GSTIN format: Same 15-digit structure. First 2 digits: state code of the state where the non-resident intends to supply.

Practical application: Foreign companies exhibiting at Indian trade shows, executing projects in India, or providing services from a temporary establishment. Also applicable to foreign e-commerce operators serving Indian customers.

Virtual Auditor handles GST registration for foreign companies and non-resident individuals, including authorised representative arrangement and advance tax deposit computation.

State-Wise GST Registration Nuances

While GST is a national tax, the registration process has state-specific nuances that cause confusion and rejection:

Tamil Nadu: officers verify the principal place of business closely, but a residential or shared premises is permitted with the prescribed proof — an ownership document, or the rent or lease agreement or a consent letter together with the owner's identity and ownership proof; CBIC Instruction No. 03/2025-GST (17 April 2025) bars demands for documents beyond the prescribed list and Circular No. 257/03/2026-GST (26 October 2026) fixes the REG-01 document list. Aadhaar authentication may face OTP delays in certain districts.

Karnataka: Bangalore-specific: many co-working space addresses face additional scrutiny. The officer may schedule a physical verification visit. We advise on address documentation that satisfies Karnataka GST officers.

Maharashtra: Mumbai registrations face high volume — processing times may be longer (7-10 days vs. 3-5 in other states). Additional documentation for Shops and Establishments Act number may be requested.

Multi-state registration: Businesses operating in multiple states need separate GSTIN per state. Each registration requires a state-specific address proof and authorised signatory. We handle multi-state registrations as a package, ensuring consistent classification (HSN/SAC codes) across all states to avoid reconciliation issues in GST returns.

Virtual Auditor has office presence in Tamil Nadu (Chennai), Karnataka (Bangalore), and Maharashtra (Mumbai), giving us firsthand knowledge of state-specific GST registration requirements and officer expectations in these three major commercial states.

What has changed in the law — reviewed November 2026

• Income-tax Act, 2025: assented to on 21 August 2025 and in force from 1 April 2026, it replaces the Income-tax Act, 1961 for tax year 2026-27 onward, and the Income-tax Rules, 2026 (notified 20 March 2026) replace the 1962 Rules. Section and rule numbers on this page are those of the 1961 Act and 1962 Rules, which continue to govern assessments, appeals and pending proceedings for assessment years up to 2026-27; for tax year 2026-27 onward the corresponding provisions of the 2025 Act apply, and our engagement letters quote both.
• GST demands for tax periods from FY 2024-25 onward are raised under section 74A of the CGST Act, 2017 (inserted by the Finance (No. 2) Act, 2024, in force from 1 November 2024) with one time limit — notice within 42 months of the annual-return due date and order within 12 months of the notice — and a 60-day window for reduced penalty; sections 73 and 74 continue to apply to tax periods up to FY 2023-24.
