Did you know that a business operating in just 10 states today must maintain 10 separate GSTINs, file 10 sets of returns, and deal with 10 different state tax authorities every single month?
That compliance burden is now officially under review. On July 21, 2026, reports confirmed that the Central Board of Indirect Taxes and Customs (CBIC) is actively weighing a proposal for centralised GST registration under a single PAN for multi-state businesses. This is one of the most significant potential reforms since GST was introduced in 2017.
If you run a business with operations across multiple states, this could change how you register, file returns, and interact with tax authorities. If it works as proposed, the days of managing fragmented GSTINs may be numbered.
In this guide, we break down exactly what centralised GST registration means, why CBIC is considering it, what the current problems are, and most importantly, what you should do right now. This analysis is based on official CBIC signals, expert commentary, and nine years of tracking GST reform closely at GSTRegistration.co.
What Is Centralised GST Registration and Why Is CBIC Proposing It?
Centralised GST registration is a proposed system where a business with operations in multiple states can register under GST once, using a single PAN, and receive one unified registration valid across all states. Currently, each state requires a separate GSTIN. The CBIC is evaluating this change to reduce compliance burden and improve ease of doing business for multi-state taxpayers.
Right now, India's GST architecture is built on a state-first model. Every state where you have a taxable presence requires its own GSTIN. That means separate applications, separate audits, separate return filings, and separate communications with state GST authorities.
For a small business expanding from Rajasthan to Gujarat and Maharashtra, this means three separate registrations from day one. For a national retail chain or an MSME exporter supplying across India, this multiplies into dozens of GSTINs, each with its own compliance calendar.
This duality, where PAN functions as the core business identifier across the GST ecosystem while GSTINs remain fragmented across states, creates operational friction particularly severe for businesses with multi-state presence.
The CBIC's July 2026 proposal to form a working group to evaluate centralised registration under one PAN addresses this friction directly. It is the clearest official signal yet that this reform is being taken seriously at the policy level.
What Is the Current Problem with Multi-State GST Registration?
To understand why this proposal matters, you need to understand exactly what multi-state businesses deal with today.
Multiple GSTINs, Multiple Headaches
Under Section 22 of the CGST Act, a person carrying out taxable activities in a state must obtain GST registration in that state. This results in multiple GSTINs for the same PAN-holding entity.
Each GSTIN carries its own obligations: GSTR-1, GSTR-3B, GSTR-9 annual return, e-way bill generation, ITC reconciliation, and state-authority correspondence. The more states you operate in, the more this multiplies.
Common pain points multi-state businesses face:
-
Duplication of effort: The same business documents, PAN details, and promoter credentials are submitted again and again to different state authorities.
-
Multiple audit risks: Each state can independently scrutinize your GSTIN, meaning multiple simultaneous audits are possible.
-
ITC complexity: When goods move between your own state entities (called distinct persons under Section 25(4) of the CGST Act), GST is chargeable on inter-unit transfers, requiring a tax invoice for movement of your own goods. As CBIC clarified in September 2025, where a business entity operates from warehouses or cold storage facilities in multiple states under the same PAN, each such establishment is considered a separate taxable person.
-
Cash flow impact: ITC earned in one state cannot be directly used in another state without the movement-of-goods-with-invoice process.
-
Scaling barrier for MSMEs: For a growing MSME entering its second or third state, the compliance jump is often the single biggest deterrent to formal geographic expansion.

What Exactly Is CBIC Proposing in July 2026?
CBIC's July 2026 proposal involves forming a high-level working group to evaluate whether multi-state businesses can be allowed to register under GST once using their PAN, receiving a single unified registration authority instead of state-specific GSTINs. The group is expected to study legal feasibility, technology changes needed in the GST portal, and whether the system should be optional or mandatory for eligible taxpayers.
The core idea draws from the pre-GST era. Before 2017, large multi-state service-tax payers could register as a Large Taxpayer Unit (LTU), which gave them a centralized assessment and filing structure. GST eliminated this model in favor of state-specific registrations. The 2026 proposal could bring back a modernized version of centralized compliance.
What the working group is expected to examine:
-
Whether centralised registration can legally coexist with the state-based GST framework under the Constitution
-
What changes are needed to the GSTN technology infrastructure to support one-PAN, multi-state returns
-
Whether the system should be opt-in (for large taxpayers first) or eventually mandatory
-
How revenue-sharing between the Centre and states will be handled under a unified registration
-
What safeguards prevent misuse, particularly for ITC fraud detection across state boundaries
The government's broader direction is clear. Finance Minister Nirmala Sitharaman has publicly called on CBIC officials to make GST registration easier and reduce procedural friction for genuine taxpayers.
How Would Centralised GST Registration Actually Work for Your Business?
This is the question most business owners and CAs will immediately ask. While the final design depends on the working group's recommendations, the proposed model would likely work as follows.
Step 1: Single Application Under PAN
Instead of filing GST REG-01 separately in each state, you would submit one centralized application. Your existing PAN already functions as your base identity across the GST system, linking your returns, e-invoices, e-way bills, and payments. A PAN-led architecture enables holistic data analytics, linking registration details with return filings, e-invoicing, e-way bills, and banking data, allowing authorities to focus on risk-based detection rather than procedural scrutiny.
Step 2: One Registration Certificate, Multiple State Codes
Under this model, your GSTIN may retain the existing 15-digit structure but be issued centrally, with the system tracking your presence across states internally rather than requiring separate registrations per state.
Step 3: Centralized Return Filing
Instead of filing GSTR-1, GSTR-3B separately for each state, you would file consolidated returns that the system automatically allocates to the relevant states for revenue-sharing purposes.
Step 4: Single Authority for Assessment
Rather than dealing with 10 different state commissioners, you would interact with one designated Central GST authority, similar to how the LTU system worked under the pre-GST service tax regime.
For businesses currently managing multi-state turnover, understanding where you stand on the GST turnover limit for registration thresholds in each state is still essential in the interim. Our guide on GST turnover limits and registration thresholds 2026 covers this in detail.
Who Benefits Most from This Proposed Reform?
Not every business would benefit equally. Understanding which category you fall into helps you assess whether this reform is worth tracking closely.
Businesses That Would Benefit Most
E-commerce sellers and marketplace operators: Businesses selling across India on Amazon, Flipkart, or Meesho are already required to register in every state where they have warehouses or fulfil orders. Our detailed guide on GST registration for e-commerce businesses explains the current obligations, which are among the most complex for multi-state operations.
MSMEs expanding geographically: The moment an MSME opens a second warehouse in a neighbouring state, it must register there. For a business doing ₹1-2 crore in that state, the compliance cost of a new GSTIN often exceeds the tax itself. One of the biggest deterrents to formal expansion is the compliance jump triggered by entering new states.
Importers using third-party warehouses: Following CBIC's September 2025 circular, importers storing goods in other states' warehouses must register in those states even if they have no direct employees or offices there. Centralised registration would eliminate this friction.
Startups scaling nationally: A D2C startup that starts in one city and scales to pan-India distribution faces a growing GSTIN portfolio that is administratively burdensome and expensive to maintain.
IT and service companies: Technology companies providing services from one state to clients across India, while having offices in multiple cities, manage complex ITC allocation and filing obligations across states.
Who Should Watch and Wait
Small businesses operating in a single state: If your business is registered in one state and operates locally, this reform has no direct impact on you. Your current single-state GSTIN works perfectly well, and centralised registration is unlikely to be relevant for you.
Composition scheme taxpayers: Composition dealers file simpler quarterly returns and are unlikely to be included in the first phase of centralised registration even if it passes.
What Are the Challenges and Concerns with Centralised GST Registration?
Every significant GST reform faces legitimate concerns, and this one is no exception. Understanding the challenges helps you follow the working group's progress with the right context.
Constitutional and Revenue-Sharing Complexity
GST is a dual-indirect tax. Both the Centre and the states share revenue, with state GST (SGST) forming a significant part of every state's finances. If a business files one consolidated return, the system must accurately apportion revenue to each state based on where consumption or supply occurred. Getting this attribution right technically and legally is the biggest challenge the working group faces.
Technology Readiness of GSTN
The GST Network (GSTN) handles hundreds of millions of returns, e-invoices, and e-way bills annually. A shift to centralized registration would require significant architectural changes to how GSTINs are issued, how returns are mapped, and how state-level analytics are generated. GSTN's track record shows that large-scale changes take 12-18 months to implement even after policy approval.
Risk of Misuse
Multi-state ITC fraud is already a significant enforcement concern. A centralized registration model must ensure that the data analytics advantage outweighs any new vectors for large-scale ITC manipulation. The CBIC's experience with e-invoicing and IMS suggests the technology foundation exists, but the risk models need careful design.
Resistance from States
Several states have historically been protective of their GST jurisdiction and audit powers. A move to centralized assessment could face political resistance, particularly from larger states that generate significant SGST revenue and have invested in state-level GST administration infrastructure.

Trust and Authority: Expert Perspective on This Reform
The demand for centralised GST registration has come consistently from India's business community over the past nine years. Industry bodies including CII, FICCI, and the MSME associations have repeatedly raised the multi-GSTIN compliance burden in their pre-budget and GST Council memoranda.
The 2026 CBIC initiative represents the first time this demand has moved from industry wishlist to an active government working group with a defined mandate and timeline.
Original insight from GSTRegistration.co: The most significant thing about this proposal is not what it would simplify, but what it signals. CBIC is moving from "one nation, one tax" toward "one nation, one taxpayer identity." That is a meaningful shift in the regulatory philosophy of GST, and it matters for how compliance architecture will evolve over the next five years.
The reform trajectory since GST 2.0 was introduced in September 2025, with rate rationalization, GSTR-3B liability locking, and IMS, all point in one direction: more technology-led compliance with less manual state-level intervention. Centralised registration fits perfectly into that direction.
At GSTRegistration.co, we have been tracking GST compliance requirements for businesses of all sizes since the rollout of GST in 2017. We have helped thousands of businesses navigate multi-state registration complexities. Our view: if this reform passes in the form currently proposed, it will be the most business-friendly structural change to GST since the composition scheme was expanded.
What Should Multi-State Businesses Do Right Now?
The working group has been tasked with reporting its findings, which means a final policy decision is still months away. Here is what makes sense to do in the interim.
If you are already registered in multiple states: No action required immediately. Continue filing under your existing GSTINs. Monitor CBIC circulars for any official notification on the centralised registration pilot or rollout timeline.
If you are planning to expand to a new state soon: Proceed with the standard state-level GST registration process, as there is no indication that a transition will happen within the next six months. Our complete GST registration guide for 2026 and the list of documents required for GST registration will help you through the current process.
If you are an MSME considering geographic expansion: Use this reform signal as a planning indicator. If you are delaying expansion specifically because of multi-state compliance cost, the direction of travel is favorable. But plan for 12-24 months before centralised registration becomes available even in pilot form.
If you have recently received a GST notice related to multi-state operations or distinct-person transactions: The proposed reform does not change current law. Get your notice handled under the existing framework. See our GST SCN reply guide for detailed assistance.
Conclusion: 3 Key Takeaways
1. Centralised GST registration is officially on the government's agenda for the first time. CBIC's July 2026 working group announcement is not speculation. It is a formal policy examination of one of the most requested GST reforms since 2017.
2. The reform would matter most for multi-state businesses, e-commerce operators, and MSMEs scaling nationally. If you operate across more than two states, track this development closely. The compliance, cash flow, and administrative benefits could be material.
3. No action is required today, but positioning is important. Current multi-state GST registration requirements remain in full force. Use the time before this reform lands to ensure your existing GSTINs are clean, compliant, and properly linked. A smooth transition to any centralised system will be much easier from a position of compliance strength.
Q1: What is centralised GST registration under one PAN?
Centralised GST registration under one PAN is a proposed system that would allow businesses operating in multiple states to register under GST once, using their existing PAN, instead of obtaining separate GSTINs for each state. CBIC is evaluating this in 2026 through a dedicated working group.
Q2: Is centralised GST registration available now?
No. As of July 2026, centralised GST registration is a proposal under evaluation by CBIC. The current law still requires separate GSTIN registration in each state where a business has taxable operations. No date for implementation has been announced.
Q3: Who needs to register for GST in multiple states?
Any business with taxable supplies, a warehouse, a place of business, or employees in more than one state must register for GST in each of those states separately under the current rules, regardless of whether the annual turnover in that state exceeds the threshold.
Q4: What are the benefits of a single PAN GST registration for multi-state businesses?
The key benefits would include reduced compliance burden (one return instead of many), lower cost of maintaining multiple GSTINs, simplified document management, single-authority audit risk, and easier ITC management across states.
Q5: Will this reform affect the GST composition scheme?
Composition scheme taxpayers, who file simplified quarterly returns and have turnover below the composition limit, are unlikely to be included in the first phase of centralised registration. The proposal appears primarily directed at regular taxpayers with significant multi-state turnover.
Q6: What is a GSTIN and how is it different from a PAN?
A GSTIN is a 15-digit Goods and Services Tax Identification Number assigned to a business when it registers for GST in a state. It includes the state code, the business's PAN, and an entity code. PAN (Permanent Account Number) is a single 10-digit identifier issued by the Income Tax department that stays the same regardless of how many states a business operates in. Under centralised registration, PAN would become the primary identifier for GST as well. You can learn more in our guide on what is a GST number.
Q7: How does this compare to the pre-GST Large Taxpayer Unit system?
Before GST, the service tax regime allowed large taxpayers to register as a Large Taxpayer Unit, which gave them centralised filing and assessment. GST replaced this with state-specific registrations in 2017. The current proposal to consider centralised registration represents a partial return to the LTU concept, updated for the digital GST infrastructure.
Q8: Where can I apply for GST registration for multiple states right now?
Currently, you must apply separately in each state through the official GST portal at gst.gov.in. Our free online GST registration guide covers the step-by-step process for each state application.
Is your business operating across multiple states? Managing multiple GSTINs, filing separate returns, and handling state-by-state compliance is expensive and time-consuming.
