Fast-Track Merger under Section 233, Companies Act 2013

A fast-track merger under Section 233 of the Companies Act, 2013 is a simplified route to merge or amalgamate certain companies with the approval of the Central Government, acting through the Regional Director, instead of the National Company Law Tribunal. It removes the tribunal-convened meetings and the sanction hearing that the ordinary merger route requires. For eligible companies, it can complete in roughly 60 days once the scheme is filed, and after the September 2025 amendment the pool of eligible companies is much wider than it used to be.

This article sets out who can use a fast-track merger under Section 233, the step-by-step process and forms, how the Regional Director route compares with Sections 230-232, and the cost, timeline and pitfalls to plan for.

The route exists for a practical reason. Company mergers used to sit in a queue before the tribunal for the better part of a year, even when nobody objected and the deal was a straightforward tidy-up inside a corporate group. Section 233, in force since 15 December 2016, was built to move those low-controversy mergers out of that queue.

Who does this matter to now? Small companies, startups, and, since the 2025 reforms, mid-market unlisted groups and holding-subsidiary structures that until recently had no choice but the full tribunal process. If you advise founders or run secretarial compliance, this is a route worth knowing cold.

A fast-track merger is a simplified amalgamation under Section 233 of the Companies Act, 2013, available to eligible companies such as two small companies, a holding company and its subsidiary, and startups. It is approved by the Regional Director, not the NCLT, and can complete in about 60 days.

What follows is the current law: eligibility after the 2025 expansion, the exact CAA forms, the approval thresholds, and the practical gap between the statutory timeline and how long these mergers really take.

How a fast-track merger works under Section 233

A fast-track merger under Section 233 works by replacing tribunal approval with an administrative approval by the Regional Director. The scheme is drawn up, approved by the members and creditors of each company, and then confirmed by the Regional Director acting for the Central Government. There’s no petition to the National Company Law Tribunal, no tribunal-directed meetings, and no sanction hearing.

That single change is what makes it “fast”. Under the ordinary route, a company files a petition and waits for the tribunal to direct meetings, hear objections, and finally sanction the scheme. Section 233 collapses that into a filing-and-confirmation process run through the office of the Regional Director.

The Regional Director route instead of the NCLT

The legal machinery sits in Section 233 of the Companies Act, 2013 read with Rule 25 of the Companies (Compromises, Arrangements and Amalgamations) Rules, 2016. Both came into force on the same day, 15 December 2016. The section gives the power to approve these mergers to the Central Government, and the Central Government has delegated that power to the Regional Directors who head the Ministry of Corporate Affairs regions.

So when practitioners talk about “RD approval” for a merger, this is what they mean. The Regional Director receives the scheme, checks it against the objections (if any) from the Registrar of Companies and the Official Liquidator, and either confirms it or, in limited circumstances, sends it to the tribunal. For a plain-language overview of fast-track mergers, iPleaders has a useful primer, though note it predates the 2021, 2024 and 2025 amendments that reshaped eligibility.

A common question is whether the tribunal has any role at all. In the normal case, no. The tribunal only enters the picture if the Regional Director believes the scheme is not in the public interest or the interest of creditors, and even then the Regional Director cannot simply reject it. More on that in the section on objections.

How the fast-track route grew, 2016 to 2025 [HISTORICAL]

The route started narrow and has widened steadily. In 2016 it covered only two categories: two or more small companies, and a holding company merging with its wholly-owned subsidiary. On 1 February 2021, the Ministry extended it to startups, letting two startups, or a startup and a small company, use it. In September 2022, the thresholds that define a “small company” were raised, which quietly enlarged the eligible pool again.

Then came two bigger shifts. A 2023 amendment rebuilt the approval timeline and added a firm deemed-approval backstop. A 2024 amendment opened a cross-border version for foreign parents merging into their Indian subsidiaries. And in September 2025, the biggest expansion yet brought in mid-sized unlisted companies, non-wholly-owned subsidiaries and demergers. The direction of travel is clear: each revision has pulled more restructurings out of the tribunal and into the Regional Director’s office.

Companies eligible for the fast-track route

The companies eligible for a fast-track merger under Section 233 are set out in Rule 25, and the list widened sharply in September 2025. Getting eligibility right is the first thing to check on any deal, because a company that doesn’t fit one of the prescribed classes simply cannot use the route, however straightforward its merger looks.

The base classes: small companies and holding-subsidiary groups

Two categories have been eligible since day one. The first is a merger between two or more small companies. The second is a merger between a holding company and its wholly-owned subsidiary, which is the classic group clean-up where a parent absorbs a 100% owned subsidiary it no longer needs to keep separate.

These two classes still carry most of the volume in practice. A parent folding a dormant subsidiary into itself, or two small group companies combining, is exactly the kind of low-risk restructuring the route was designed for. If a subsidiary has genuinely stopped trading, it’s worth comparing this route against simply closing a company through strike-off, which can be cheaper when there are no assets or liabilities to carry across.

Startups and small companies

Since 1 February 2021, startups have their own eligibility. Two or more startup companies can merge through the fast-track route, and so can a startup together with one or more small companies. “Startup” here means a company recognised as one by the Department for Promotion of Industry and Internal Trade, not just any early-stage business that calls itself a startup.

In practice, this matters less often than founders expect. Most startup deals are share purchases or acquisitions, not statutory mergers, so Section 233 applies only to the specific case of two recognised startups (or a startup and a small company) actually amalgamating. It’s a narrower door than the “startup merger” search suggests.

The September 2025 expansion

The Companies (Compromises, Arrangements and Amalgamations) Amendment Rules, 2025, notified on 4 September 2025 and in force from 8 September 2025, widened the route dramatically. Four new situations now qualify.

First, two or more unlisted companies (other than Section 8 companies) can use the route, provided each company’s aggregate outstanding loans, debentures and deposits does not exceed ₹200 crore and there’s no subsisting default in repayment. Second, a holding company can now merge with a subsidiary that is not wholly owned, as long as the transferor is not a listed company. Third, two or more subsidiaries of the same holding company (fellow subsidiaries) can merge with each other. Fourth, the rules formally brought demergers and the division or transfer of an undertaking within the fast-track framework.

This is the change practitioners now call “Fast-Track Mergers 2.0”, and it’s the single biggest reason the route’s usage is expected to climb. The ₹200 crore borrowing test alone admits a large swathe of mid-market companies that were previously forced into the tribunal.

Who is still excluded, and what “small company” means

Not everyone gets in. Listed companies remain outside the new unlisted-company classes, and Section 8 (not-for-profit) companies are excluded from the ₹200 crore class. Where eligibility turns on being a “small company”, the definition in Section 2(85) of the Companies Act, 2013 controls, and it’s stricter than many assume.

As most recently revised with effect from 1 December 2025, a small company is a company (other than a public company) with paid-up share capital of not more than ₹10 crore and turnover of not more than ₹100 crore. Both limits must be met, not just one. And a holding company, a subsidiary, a Section 8 company, or a company governed by a special Act can never be a small company, regardless of its size. One persistent myth is worth killing here: the fast-track route is not limited to public companies. Private companies are in fact its main users.

Section 233 versus Sections 230-232

Section 233 differs from Sections 230-232 mainly in who approves the merger and how long it takes. Both are legitimate ways to merge Indian companies, and, importantly, Section 233 is optional. An eligible company can still choose the tribunal route if it prefers, a point covered below.

What actually changes between the two routes

The headline difference is the approving authority. Under the ordinary route in Sections 230 to 232 of the Companies Act, 2013, the company petitions the National Company Law Tribunal, which convenes meetings of members and creditors, hears any objections, and then sanctions the scheme. Under Section 233, the Regional Director does the approving and there are no tribunal-convened meetings at all.

That flows into every other difference: timeline, cost, and the sheer number of steps. The tribunal route is commonly cited as taking nine to twelve months; the fast-track route carries a 60-day statutory backstop once the scheme is filed. The trade-off is scope. Sections 230-232 are open to any company and can handle contested, complex, multi-class schemes, while Section 233 is open only to the eligible classes and works best for clean, uncontested deals. For the full picture of the tribunal process, our guide to the scheme of arrangement under Sections 230-232 walks through it in detail, and it helps to understand how M&A deal structures compare in India before committing to any one path.

When eligible companies should still choose the NCLT route

Here’s something that surprises people: being eligible for the fast-track route doesn’t always mean you should use it. In practice, three situations push companies back towards Sections 230-232 even when they qualify for Section 233.

The first is a real risk of dissent from shareholders or creditors, where a tribunal-sanctioned scheme carries more finality. The second is a contested or delicate valuation, where the tribunal’s scrutiny actually protects the company from later challenge. The third is a merger involving substantial immovable property, where a tribunal order can smooth the transfer and registration in a way an administrative order sometimes doesn’t. When any of these is present, the “slower” route can be the safer one.

Step-by-step fast-track merger procedure

The fast-track merger procedure under Section 233 runs through a fixed sequence of steps and a defined set of CAA e-forms. Miss a form or a threshold and the Regional Director will send it back, which is the most common reason these “fast” mergers slow down. Here is the sequence each company follows.

Board approval and the notice inviting objections

Each company’s board first approves the draft scheme of merger. The transferee and transferor companies then send a notice inviting objections or suggestions to the Registrar of Companies and the Official Liquidator having jurisdiction, in Form CAA-9, allowing 30 days for a response. Since the September 2025 amendment, that notice must also go to any sectoral regulator (such as the RBI or SEBI) and to the stock exchanges where a company involved is regulated or listed.

This step is easy to underestimate. The Registrar and the Official Liquidator use this window to flag concerns, and their objections are what the Regional Director weighs later. A well-drafted scheme anticipates the obvious objections rather than waiting to receive them.

Declaration of solvency

Before the meetings of members and creditors, each company files a declaration of solvency with the Registrar of Companies in Form CAA-10. The declaration confirms the company can meet its liabilities, which is the reassurance creditors are entitled to when a merger reshuffles the corporate structure.

Companies relying on the new unlisted-company class carry an extra certification here. Since September 2025, they must file an auditor’s certificate in the new Form CAA-10A, confirming they meet the ₹200 crore debt limit and the no-default condition (this is separate from the solvency declaration). That adds an auditor sign-off, so building the timeline around your auditor’s availability is worth planning for.

Member and creditor approval

The scheme then needs approval from both members and creditors, and the thresholds are precise. Members must approve it in a general meeting by a majority holding at least 90% of the total number of shares. Creditors must approve it by a majority representing nine-tenths (that is, 90%) in value of the creditors or class of creditors.

Note the difference carefully, because it trips up even experienced teams. The member threshold is 90% of the total number of shares, not 90% of those who turn up and vote. The creditor threshold is measured in value, not headcount. Both approvals can be obtained at a meeting held on 21 days’ notice, or by written consent from the required majority, which is often the faster path for closely held companies. A recurring practical difficulty is reaching 90% of total shares when the shareholding is scattered; a single untraceable minority block can stall an otherwise clean merger.

Filing the scheme and the Regional Director’s order

Once approved, each company files the scheme, along with the results of the meetings and the objections received, with the Central Government (through the Regional Director) in Form CAA-11, with copies to the Registrar of Companies and the Official Liquidator. The September 2025 amendment extended the window for this filing from 7 days to 15 days after the meetings, a small but welcome bit of breathing room.

If the Regional Director is satisfied, it registers the scheme and issues a confirmation order in Form CAA-12. The Registrar then records the merger, and the transferor company is dissolved without any separate winding-up process. On the question of a valuation report: it is generally required, though for a merger of a wholly-owned subsidiary into its holding company, where no shares are issued as consideration, a valuation report is often unnecessary because there’s no share-exchange ratio to justify.

Regional Director approval, objections and the 60-day deemed approval

After the scheme is filed, the Regional Director must confirm it, object to it, or let the 60-day deemed-approval clock run out. This stage is where the “fast” in fast-track is won or lost, and the 2023 amendment tightened it considerably.

The 30, 15 and 60-day clock

The current timeline came in with the Companies (Compromises, Arrangements and Amalgamations) Amendment Rules, 2023, effective 15 June 2023. It works in three parts. The Registrar of Companies and the Official Liquidator have 30 days to send their objections or suggestions to the Regional Director. If no objections come in (or the objections aren’t sustained) and the Regional Director is satisfied the scheme is in the public and creditor interest, it must issue the confirmation order within 15 days after that 30-day period.

And here’s the backstop that gives the route its certainty. If the Regional Director neither issues a confirmation order nor files an application with the tribunal within 60 days of receiving the scheme, it is deemed to have no objection, and confirmation is taken to have been given. So a company isn’t left waiting indefinitely on an overloaded desk; silence past 60 days works in its favour.

What happens on objections or dissent

What if the Registrar or the Official Liquidator does object, or the Regional Director thinks the scheme prejudices creditors? This is the part most guides get wrong. The Regional Director cannot simply reject the scheme. If it believes the scheme is not in the public interest or the interest of creditors, it must file an application before the tribunal under Section 233(5) of the Companies Act, 2013, asking the tribunal to consider the scheme under the ordinary Section 232 route.

The Bombay High Court settled this in Asset Auto India Pvt. Ltd. v. Union of India (Bombay High Court, 2024), where the Regional Director had rejected a scheme among a holding company and its subsidiaries outright. The court read the word “may” in the relevant sub-section as effectively mandatory: the Regional Director’s only options are to confirm the scheme or to refer it to the tribunal, not to throw it out. That ruling is the leading authority on the limits of the Regional Director’s power in a fast-track merger, and it’s worth citing in any objection response.

Public-interest and valuation scrutiny

The public-interest ground is not a formality. A scheme can be refused where the exchange ratio is unfair or the valuation doesn’t hold up, because the whole point of the scrutiny is to protect minority shareholders and creditors who had no real say. The National Company Law Appellate Tribunal took exactly this view in Wiki Kids Ltd. v. Regional Director, South East Region (NCLAT, 2017), refusing to sanction an amalgamation whose share-exchange ratio funnelled disproportionate value to common promoters on a valuation the shareholders couldn’t rely on.

That case arose under the tribunal route rather than Section 233 (the transferee there was a listed company), so it’s an analogy rather than a direct fast-track precedent. But the principle carries across. Because the Regional Director route has lighter scrutiny than the tribunal, a promoter tempted to push through an aggressive valuation is precisely the risk the public-interest referral is meant to catch.

Cross-border fast-track mergers and reverse flips

A cross-border fast-track merger lets a foreign holding company merge into its wholly-owned Indian subsidiary under Rule 25A. This “inbound” version of the route was opened by a September 2024 amendment and has become one of the more talked-about uses of Section 233.

How the inbound reverse-flip works

Under Rule 25A, a foreign company that is the holding company can merge into its Indian wholly-owned subsidiary through the fast-track process, with the Indian company as the transferee. It comes with conditions the domestic route doesn’t have. Both companies need prior approval from the Reserve Bank of India, and the merger must comply with the Foreign Exchange Management (Cross Border Merger) Regulations, 2018.

There’s also a national-security filter. The companies must declare whether the foreign transferor is from a country that shares a land border with India, and if so, whether the prior government approval required for such investments has been obtained. That declaration reflects the Press Note 3 regime and shouldn’t be treated as a box-ticking formality. For the wider approval landscape on these deals, our guide to the cross-border M&A approval timeline in India sets out how the RBI and FEMA pieces fit together.

Why founders are using it [SECOND-ORDER]

The interesting part is why this route suddenly matters. A generation of Indian startups incorporated their holding company abroad, then found that re-domiciling the parent back to India ahead of an Indian IPO used to mean a slow, expensive tribunal process. The fast-track reverse-flip makes that “flip back” cheaper and faster, without an NCLT petition.

Practitioners expect this to feed a steady stream of reverse-flip mergers as more foreign-parented Indian companies prepare to list at home. It’s a good example of how a technical rule change ripples outward: a merger provision aimed at simplifying group restructuring ends up shaping where India’s fastest-growing companies choose to domicile.

Timeline, cost and practical pitfalls

The real timeline and cost of a fast-track merger are usually longer and higher than the 60-day headline suggests. The route is genuinely faster than the tribunal, but treating “60 days” as the total project time is the fastest way to disappoint a client.

The 60-day statutory promise versus the real timeline

The 60 days is the Regional Director’s confirmation window, measured from when the scheme is filed. It doesn’t include everything that has to happen first: drafting the scheme, holding board meetings, issuing the CAA-9 notices and waiting out the 30-day objection period, obtaining the solvency declaration and the new auditor’s certificate, and convening or securing written consent from members and creditors.

Add those up and a realistic end-to-end timeline is closer to three to four months for a clean deal, and longer if the Regional Director raises queries. One well-known commentary from a professional body has noted that a poorly managed fast-track merger can end up taking about as long as the tribunal route it was meant to avoid. The lesson: the statutory clock is real, but it starts late in the process.

Cost, stamp duty and immovable property

Cost is the other area where expectations need managing, and it’s where almost every online guide goes silent. The direct government filing fees are modest, but the professional fees for drafting the scheme, running the approvals and handling the forms are the real spend, and they scale with the complexity of the group. Rather than quote a figure that varies widely by deal, the honest answer is to budget for professional fees as the main line item, not the filing fees.

Stamp duty is the sharper trap. A merger transfers the assets of the transferor to the transferee, and that transfer can attract stamp duty, which is a state subject and varies from state to state. Where the merger moves immovable property, teams sometimes find that registering the transfer under an administrative Regional Director order is less smooth than under a tribunal order, and larger mergers may also need clearance from the Competition Commission of India where the deal crosses the merger-control thresholds. None of this defeats the route; it just means the “cheaper and faster” pitch needs an asterisk.

Common mistakes and where the route is heading [FUTURE] [SECOND-ORDER]

The common mistakes cluster in a few places: misjudging eligibility after the 2025 changes, underestimating the 90%-of-total-shares hurdle, and assuming a valuation report is never needed. Each is avoidable with a proper pre-merger check. Treat eligibility and the shareholder maths as gating items before you promise a client a timeline.

Looking ahead, the fast-track route is likely to carry a growing share of India’s mergers as the 2025 expansion beds in, and practitioners are already watching how it interacts with the new Income-tax Act, 2025 on the carry-forward of losses and tax attributes. There’s a quieter structural effect too. As eligibility widens, oversight shifts from a judicial forum (the tribunal) to an administrative one (the Regional Director), and the 60-day deemed-approval default means an overburdened office’s inaction results in automatic sanction. That’s efficient, but it puts more weight than before on companies and their advisers to get minority and creditor protection right themselves.

Frequently asked questions

What is a fast-track merger under Section 233 of the Companies Act, 2013?

It’s a simplified merger or amalgamation route for certain classes of companies, approved by the Central Government through the Regional Director rather than by the National Company Law Tribunal. It skips the tribunal-convened meetings and sanction hearing of the ordinary route. Eligible companies include two small companies, a holding company and its subsidiary, and startups. Once the scheme is filed, it carries a 60-day statutory approval backstop.

Which companies are eligible for a fast-track merger after the September 2025 amendment?

The long-standing classes are two or more small companies, a holding company and its wholly-owned subsidiary, and startups (two startups, or a startup with a small company). From 8 September 2025, the route also covers two or more unlisted companies whose aggregate loans, debentures and deposits do not exceed ₹200 crore with no default, a holding company merging with a non-wholly-owned subsidiary (transferor not listed), fellow subsidiaries of the same holding company, and demergers. Listed transferors and Section 8 companies remain excluded from the new classes.

Is NCLT approval required for a fast-track merger?

No. That’s the defining feature of the route. Approval comes from the Regional Director acting for the Central Government, not the tribunal. The tribunal only becomes involved if the Regional Director believes the scheme is against the public interest or creditors’ interest, in which case it must refer the scheme to the tribunal rather than reject it.

How long does a fast-track merger actually take?

The statutory approval window is 60 days from filing the scheme with the Regional Director. But the full process, drafting, board approvals, the 30-day objection notice, solvency declaration, and member and creditor approvals, usually adds up to about three to four months for a clean deal. Queries from the Regional Director can extend it further.

What is the 60-day deemed-approval rule under Section 233?

If the Regional Director neither confirms the scheme nor files an application with the tribunal within 60 days of receiving it, the Regional Director is deemed to have no objection and confirmation is treated as given. It’s a backstop that protects companies from indefinite delay. It doesn’t mean every merger is decided on day 60; many are confirmed sooner.

Can a private limited company use the fast-track merger route?

Yes, and private companies are in fact the main users. A common myth holds that the route is only for public companies, which is wrong. What matters is whether the company falls within one of the eligible classes, such as a small company, a startup, or (since 2025) an unlisted company within the ₹200 crore borrowing limit.

Is a fast-track merger mandatory, or can eligible companies still use the NCLT route?

It’s optional. An eligible company can still choose to merge through Sections 230-232 before the tribunal if it prefers. Companies sometimes do exactly that when there’s a real risk of dissent, a contested valuation, or a large immovable-property transfer, because a tribunal-sanctioned scheme can offer more finality.

Is a valuation report required for a fast-track merger?

Usually yes, to justify the share-exchange ratio between the merging companies. The main exception is a merger of a wholly-owned subsidiary into its holding company, where no new shares are issued as consideration, so there’s no exchange ratio to value. Even then, confirm the position for the specific deal rather than assuming.

Can a foreign holding company merge into its Indian subsidiary under Section 233?

Yes, under Rule 25A, which allows a foreign holding company to merge into its wholly-owned Indian subsidiary through the fast-track route. It requires prior Reserve Bank of India approval and compliance with the Foreign Exchange Management (Cross Border Merger) Regulations, 2018, plus a declaration on whether the foreign company is from a land-bordering country. This “reverse-flip” route is increasingly used by foreign-parented Indian startups preparing to list in India.
