One Nation, One GST Registration: What the Gauba Panel's New Proposal Could Change

Quick Answer

A committee led by NITI Aayog member Rajiv Gauba has put forward a proposal in June 2026: instead of businesses needing a separate GST registration in every state, a single PAN-based registration would be valid across all of India. Right now, this is only a recommendation, not law. Nothing will be final until the Centre, the GST Council, and the states discuss it, and there's no timeline yet.

If it actually goes through, it would be the biggest structural change to GST since the 2017 rollout. But the emphasis is on “if” for now.

What the Gauba Panel Actually Said

Rajiv Gauba, a former Cabinet Secretary and now a NITI Aayog member, heads the High-Level Committee on Regulatory Reforms. The committee was tasked with identifying non-financial sector reforms that would reduce the compliance burden on businesses.

The committee has suggested replacing state-by-state GSTIN registration with one unified PAN-based registration valid across the entire country. In practice, this means a business operating in Delhi, Mumbai, and Bangalore would currently need three separate registrations. Under the new proposal, one would be enough.

In a statement to Moneycontrol, a government official put it plainly:

That quote matters because it confirms this isn't just media speculation the discussion is genuinely happening within government.

This isn't a standalone idea, either. The committee has suggested more than 17 reforms for MSMEs, covering credit access, Companies Act compliance, payment dispute resolution, and CSR donations. A separate report lays out a 38-point agenda spanning tax to FSSAI and BIS rules. GST registration is just one piece of a much larger puzzle.

Honestly, this idea isn't new at all. Industry bodies and tax professionals have been asking for it for years, and it came up in Union Budget 2026 discussions too. The logic is simple PAN is already the backbone of the GST ecosystem, linking everything from returns to e-invoicing. So why not make registration PAN-based as well. The Gauba panel has essentially turned a long-standing industry demand into a formal government proposal.

A tax policy commentary made a point that probably sums up the whole debate best: “for MSMEs expanding beyond a single state, and for digital-first or distribution-led businesses, registration complexity often becomes a hidden but significant cost of compliance unrelated to tax liability, but driven purely by process.” The actual tax rate or liability won't change because of this reform only the process gets simpler.

How the System Works Right Now

It helps to understand exactly where the friction is.

Sections 22 and 25 of the CGST Act are clear wherever a business makes a taxable supply or maintains an office or warehouse, it needs a separate GST registration in that state. The PAN stays the same, but every state gets its own GSTIN.

In day-to-day terms, this means:

• A separate return has to be filed for every state's registration
• Moving goods from one state to another counts as a “supply,” which attracts IGST
• ITC is GSTIN-specific credit earned in one state can't be used directly in another
• A business operating across 15 states could end up filing more than a hundred returns a year
• Each registration needs its own accounting and reconciliation

This hits businesses trying to expand into new states the hardest e-commerce companies, logistics firms, multi-city service providers. The compliance cost has nothing to do with tax liability; it's purely a function of process complexity. In a sense, it functions like a hidden tax on growth.

Australia and Canada Already Do This

Here's something most articles on this topic don't mention a single national GST registration isn't a new or untested concept globally. Australia and Canada are both GST-based federal countries (meaning a structure similar to India's, where both the central government and states/provinces have taxing powers), and in both, a business only needs one national registration.

In Australia, every business gets an Australian Business Number (ABN), which acts as its core identifier. GST registration is linked through this number, and the flat 10% GST rate is collected under the same registration nationwide whether the business sells in Sydney or Perth.

Canada works similarly. Every business gets a 9-digit Business Number, with a program identifier added for GST/HST. This single number links the business's GST/HST, payroll, and corporate tax accounts together. So in Canada too, one root registration covers everything, despite the provinces being distinct jurisdictions.

This means what the Gauba panel is proposing isn't some untested invention it's largely an attempt to bring India in line with countries that already have a similar federal tax structure. The key difference is that India's revenue-sharing model between states is more complex, which is exactly why the transition here would be harder than it was in Australia or Canada.

Where the Real Implementation Difficulty Lies

It sounds simple to describe, but implementing it is a different matter entirely.

The Revenue-Sharing Question

GST is a destination-based tax revenue goes to wherever consumption happens, not wherever the registration is held. A single national registration would require figuring out how revenue gets divided among states. A government official told Moneycontrol:

That quote shows this is the biggest roadblock not just technical, but political too, since every state will want to protect its own revenue share.

Tracking Multiple Locations

Businesses with factories, warehouses, and branches spread across different locations would still need that data tracked separately, whether or not the registration itself is unified. Australia and Canada handle this the same way multiple “branches” or “locations” get registered under the single registration to keep reporting granular.

Managing the Transition

Existing taxpayers would need to migrate gradually; an abrupt switch would create confusion and errors. There are more than 1.4 crore registered taxpayers in the GST system right now, and a significant share of them operate across multiple states. An overnight switch could destabilise the entire system.

That's why most experts aren't pushing for a “one registration replaces everything” model outright, but rather a hybrid approach a single principal PAN-based registration, with multiple place-of-business identifiers underneath it. The idea isn't to dismantle the existing structure entirely, but to make it smarter. This approach closely resembles Canada's Business Number model, where multiple accounts sit linked under one root number.

The Constitutional and Legal Angle

It's also worth remembering that GST is itself a constitutional creature. The GST Council was created through the 101st Constitutional Amendment, which gave both the Centre and the states concurrent taxing powers. Sections 22 and 25, which mandate state-wise registration, are part of that same structure. Implementing a single national registration won't be as simple as issuing a notification it would require amendments to the CGST Act, and likely to SGST Acts as well, which each state passes individually. That process would need to go through both Parliament and State Assemblies, which takes time.

This is also why tax professionals say this reform can't happen “overnight,” no matter how strong the political will is. Even GST itself took years to get the Constitution Amendment Bill passed when it was first proposed.

When Will It Actually Roll Out

The honest answer is: nobody knows, and there's no confirmed date yet.

Here's roughly how the process will unfold:

1. The committee has made a recommendation this is a suggestion, not law
2. The Centre has started discussions with the states
3. After that, a detailed proposal will go to the GST Council
4. The GST Council, where both the Centre and all states are represented, will make the final call
5. Only once approved will a notification and timeline be announced

In a cooperative-federalism system like GST, getting consensus from the states is essential, so this could take anywhere from several months to a few years. Worth remembering GST itself was first conceived in 2000 and only rolled out in 2017, a 17-year journey. This registration reform isn't nearly as large in scope, but getting buy-in from the states will still take time.

For now, simply tracking the development is the sensible move there's no need to take any immediate action.

What This Means for Businesses

If it passes, some real benefits would follow:

• Compliance costs would drop, with documentation becoming centralised
• Starting a business in a new state wouldn't feel like a “registration penalty” anymore
• Data analytics would improve since everything would be linked through PAN, letting authorities focus more on genuine taxpayers
• MSMEs would see the most relief, since they're currently the ones most intimidated by the compliance jump that comes with multi-state expansion
• E-commerce and logistics companies, which already hold the largest number of multi-state registrations, could see their return-filing load drop dramatically

On the other side, there are genuine concerns worth discussing too:

• States worry the revenue-sharing mechanism might not work in their favour
• Tax officers would need training to adapt to the new system
• The GSTN portal's IT infrastructure would need a major upgrade to support this reform
• Businesses that have already built their accounting structures around multiple GSTINs may face duplicate work during the transition

That said, nobody needs to change their current GST registration setup right now. Until the GST Council issues an official notification, everything continues exactly as it is today. The best strategy for now is to stay in touch with your tax consultant or CA and track this development, so that when the official notification does come, you're prepared rather than scrambling.

What to Do Right Now, Step by Step

Let's make this practical. If you run a multi-state business, or you're a CA or tax consultant handling such clients, here's what makes sense to do today:

1. Build a record of your existing GSTINs. List out every state registration, its turnover, and filing status in one place. When the transition eventually happens, you'll have this data ready to go.
2. Follow GST Council announcements directly. gstcouncil.gov.in and PIB press releases remain the most reliable sources not social media rumors.
3. Start thinking about a PAN-centric accounting setup. If your ERP or accounting software is currently siloed by GSTIN, begin considering a gradual shift toward PAN-level consolidated reporting.
4. Don't panic or cancel/migrate anything prematurely. Until the notification is official, any premature action will only create confusion.
5. Discuss with your CA or tax advisor how this reform, if it happens, would specifically affect your business structure whether multi-branch, e-commerce, or service-based.

This is purely a wait-and-watch situation right now, but an informed one being prepared beats scrambling at the last minute.
