One Nation One GST Number 2026: Single GST Registration Proposal Explained

A major GST reform proposal has emerged in 2026: one PAN, one GST registration across India.

At present, a business operating from multiple states generally needs separate GST registrations in each state. This means separate GSTINs, returns, reconciliations, notices and state-wise compliance.

The proposal discussed in the transcript would replace this structure with a single nationwide GST registration linked to PAN, potentially reducing the compliance burden for businesses operating across India.

However, this reform has not been implemented yet. Reports on 4 September 2026 indicate that states have opposed the nationwide registration proposal because of concerns over jurisdiction, enforcement powers and revenue allocation. The 57th GST Council meeting is scheduled for 12 September 2026, where broader GST registration and compliance reforms are expected to be discussed.

How GST Registration Works Today

Under the present GST framework, registration is primarily state-specific.

If a company has establishments in Delhi, Maharashtra, Karnataka and Tamil Nadu and is required to register in each state, it generally obtains separate GST registrations for those states.

Each registration is treated independently for many GST purposes.

This can mean:

• Separate GSTINs;
• Separate GST returns;
• Separate reconciliations;
• Separate notices;
• Separate audits and scrutiny proceedings; and
• Separate state-level compliance teams.

For large businesses, e-commerce companies and businesses operating warehouses across India, this can significantly increase administrative work.

What Is the One Nation One GST Number Proposal?

A high-level regulatory reforms panel led by Rajiv Gauba proposed moving towards a single nationwide GST registration.

The broad concept is:

One PAN = One GST Registration for operations across multiple states.

Instead of maintaining separate registrations for every state, one registration could potentially cover the taxpayer’s operations nationally.

The proposal is aimed primarily at improving ease of doing business and reducing repetitive GST compliance.

Current System vs Proposed Single GST Registration

Particulars	Current GST System	Proposed National Registration
GST registration	Separate state-wise GSTINs	One registration linked to PAN
Returns	Multiple state-wise filings	Potential consolidated compliance
Reconciliation	GSTIN-wise	Could become centralised
Notices	Different jurisdictions	Potential central administration
Audits	State/registration specific	Could become more coordinated
Compliance cost	Higher for multi-state businesses	Potentially lower

The exact mechanics would depend on the final legal framework if the proposal is ever approved.

Why Businesses Want a Single GST Number

For businesses operating across multiple states, the compliance savings could be substantial.

Consider a company operating in 10 states.

Today, it may need to maintain 10 separate GST registrations and manage:

• GSTR-1 filing for multiple registrations;
• GSTR-3B filing for multiple registrations;
• GST reconciliations;
• ITC matching;
• Notices from multiple jurisdictions;
• Amendments to registrations;
• Audit and litigation records; and
• State-specific correspondence.

A national registration could potentially consolidate a large part of this work.

That is why the proposal is being viewed as a significant GST simplification measure.

Why States Are Opposing the Proposal

The biggest obstacle is not technology.

It is jurisdiction and federal tax administration.

According to reports, states have opposed the proposal because a national GST registration could reduce their direct administrative control over taxpayers operating within their territory.

The major concerns include:

• Who would conduct GST audits?
• Which authority would issue notices?
• Which state would investigate a taxpayer?
• How would revenue be allocated among states?
• How would local enforcement work?
• Would administration become more centralised?

These are significant questions because GST is administered jointly by the Centre and the states through the GST Council framework.

Revenue Sharing Is a Major Challenge

One of the most difficult practical questions is how GST revenue would be attributed among states if one GST registration covered the entire country.

Under the current system, state-wise registrations make it easier to identify the operations and tax liabilities attributable to a particular state.

With one national GSTIN, the system would need another mechanism for identifying:

• Place of supply;
• State-wise turnover;
• SGST entitlement;
• Input tax credit allocation; and
• Revenue settlement between states.

Government sources cited in recent reports have identified revenue allocation as one of the unresolved issues surrounding the proposal.

Has One Nation One GST Number Been Approved?

No.

This is the most important point for businesses.

The nationwide single-registration proposal should not currently be treated as a new GST rule.

The proposal was reported earlier in 2026 as a recommendation of the Rajiv Gauba-led High-Level Committee on Regulatory Reforms.

However, a 4 September 2026 report states that states have rejected the nationwide-registration proposal in its present form, effectively stalling it.

Therefore:

Businesses must continue following the existing state-wise GST registration rules unless and until the law is formally amended and notified.

GST Council Meeting on 12 September 2026

The 57th GST Council meeting is scheduled for 12 September 2026 in New Delhi, with an officers’ meeting on 11 September.

Registration simplification is expected to be an important area of discussion.

However, businesses should distinguish between three separate reform ideas currently being discussed.

1. Nationwide Single GST Registration

This is the broader proposal for one PAN-linked GST registration across India.

As of 4 September 2026, reports indicate that it has faced significant opposition from states.

2. Centralised Administration of Multi-GSTIN Taxpayers

CBIC has also been examining whether taxpayers having multiple GST registrations under one PAN could be administered more centrally.

This does not necessarily mean eliminating separate GSTINs.

It could instead mean reducing the need for businesses to deal with several different central GST formations.

3. Simplified Registration for Small E-Commerce Sellers

A separate proposal is being developed for small suppliers selling through e-commerce operators across multiple states.

The GST Council had already approved the concept in principle in 2025, and further details are expected to be considered.

These proposals should not be confused with each other.

Potential Benefits of One GST Registration

If a national GST registration system is eventually implemented, businesses could potentially benefit through:

• Fewer GST registrations;
• Lower compliance costs;
• Reduced duplication of returns;
• Easier reconciliation;
• More centralised tax administration;
• Fewer jurisdictional disputes;
• Easier expansion into additional states; and
• Better ease of doing business.

This could be particularly useful for:

• E-commerce businesses;
• Retail chains;
• Logistics companies;
• Manufacturers;
• Service companies operating nationally;
• Startups expanding across states; and
• Large corporate groups.

Could One GST Registration Reduce Litigation?

Potentially, yes.

Today, a business operating in multiple states can receive separate notices from different jurisdictions regarding similar issues.

Different authorities may also adopt different interpretations or approaches.

A more centralised structure could potentially reduce duplication.

However, centralisation itself would require clear rules governing audits, investigations and state-level enforcement.

Therefore, lower litigation cannot be guaranteed simply by introducing one GSTIN.

What Should Businesses Do Now?

Businesses should not cancel existing state-wise GST registrations or change their compliance structure based on this proposal.

For now:

1. Continue maintaining all required state registrations.
2. Continue filing state-wise GST returns.
3. Monitor recommendations from the 57th GST Council meeting.
4. Wait for amendments, notifications and implementation rules before changing compliance systems.

GST Council recommendations themselves may also require legislative amendments or notifications before they become legally effective.

Why This Reform Still Matters

Even though the nationwide registration proposal has currently faced resistance, the fact that such a major reform is being examined shows that policymakers recognise the compliance burden created by multiple state registrations.

Other simplification measures may therefore continue even if the full One Nation One GST Number model is not adopted immediately.

For multi-state businesses, the broader direction remains important: reducing repetitive registrations, streamlining administration and making national expansion easier.
