- Audit Rotation 2.0 is here.
- India’s audit market is bracing for its biggest shuffle in nearly a decade.
- Over 957 listed companies will go auditor shopping across FY2026–27 and FY2027–28.
- And with it, the familiar speech has returned: “This is the Desi Big 4 moment.” But is this time actually different?
First, let’s be honest about 2017
The first major audit rotation cycle (2017–18) was expected to disrupt the market.
In reality, it largely led to lateral movement within the same ecosystem.
Companies replaced one Big 4 firm with another. Decisions were often relationship-driven rather than capability-driven, and the overall structure of the audit market remained intact.
The numbers tell a story.
As of March 31, 2025, affiliates of the Big 6 (Deloitte, PwC, EY, KPMG, Grant Thornton, BDO), audited:
- 326 of 483 Nifty-500 companies
- 694 of 2,069 NSE-listed companies
The Big 4 alone accounted for roughly 29% of total audit fees among NSE-listed companies in FY24–25.
In terms of mandates:
- EY leads
- Followed by KPMG and Deloitte
- Walker Chandiok (Grant Thornton affiliate) ranks fourth
- MSKA (BDO affiliate) ranks fifth
- PwC comes in sixth
That last detail is telling.
As Vikas Kumar, CEO at T R Chadha, notes: “It went from Big 4 to Big 6… the market has started to evolve.”
But what actually changes in Rotation 2.0
This time, three structural shifts stand out.
Regulator is no longer passive
NFRA, India’s audit watchdog, has transformed itself from a dormant regulator into a genuinely aggressive one.
- It debarred or imposed fines on 103 auditors.
- Issued 23 disciplinary orders in 2024–25, critiquing the audit quality of several prominent listed companies.
According to Akshay Purandare, a Partner at Kirtane & Pandit (Member of KGS Alliance),
“The regulatory landscape has changed substantially compared to the 2017–18 cycle.
There is a shift firsthand, be it in audit methodologies, procedures, or documentation practices.
And firms across India are updating themselves aggressively to keep up.“
The signal is clear: audit accountability is now real.
Transparency is real
Another notable structural shift:
- Inspection reports are public
- Audit Quality Maturity Model (AQMM) scores are referenced,
- And firms are increasingly judged on capability, not just brand.
For large Indian CA firms that have invested heavily in quality infrastructure…This creates a tailwind that did not exist during the 2017 audit rotation cycle.
“Big 4 or nothing” mindset has shifted
When the RBI forced banks and NBFCs to rotate, many worked with Indian CA firms for the first time.
A lot of them were surprised.
As Akshay Purandare, Partner at Kirtane & Pandit, told us: “They gradually realised that appointing other equally capable firms may not be such a bad idea.”
That’s a quiet but important shift in how large companies think.
Add to that Vikas’s notes: “Prime Minister has explicitly spoken about the need for Indian CA firms to grow. That has created a lot of buzz.”
But CFOs aren’t charmed by narratives
Despite the momentum, large mandates remain hard to win…For CFOs and boards, the concerns are practical.
Can a firm handle the scale, geographies & tight timelines?
As one audit partner explains:
“Most large corporations don’t operate in a single geography.
The question isn’t just capability, it’s whether firms can sign off across jurisdictions and manage that complexity in time.
Global banks, investors, and analysts are also more comfortable with large audit networks.”
Can its technology stack match the Big 6?
The Big 4 and Big 6 continue to lead in audit platforms, data analytics, and documentation infrastructure.
Indian firms are catching up, but still some distance away.
Capable research team?
Clients want more than issue-spotting; they want guidance on complex accounting matters.
That requires deep technical benches and strong research capabilities, where many mid-sized firms are still catching up.
Even AI is entering the conversation
“It’s actually Boards asking about AI now,” Vikas notes, referring to expectations around deeper, data-driven assurance.
Boards want to know whether our firm is using AI and whether we can provide a higher level of assurance beyond the traditional ‘true and fair view’ required by law.”
Firms are increasingly using AI-adjacent tools for larger sample sizes, transaction-level analytics, and in some cases, near-100% coverage of specific datasets.
But as Akshay Purandare cautions, “AI in audit is still at a primitive stage.”

Bidding process has changed, too
Back in 2017, firms typically submitted presentations + pricing…All in one bid.
Today, it’s a two-stage process.
- First, you get evaluated on capability, sector knowledge, Technology stack, audit quality.
- Only after that do they open the commercial bids.
Getting into the room can take 12–18 months. And even then, winning the mandate isn’t guaranteed.
ICAI eased advertising…has it helped?
A managing partner at a Top 20 firm put it bluntly: “With all due respect… Advertising will only have a negative impact. It’s more likely to increase our costs than our revenues.”
One partner adds a sharper operational concern: “We’d probably have to add ₹2–3 crores in advertising, brand building, sponsorships… just because it’s allowed now.”
And that cost, in his view, does not translate into incremental audit wins.
Audit committees do not choose firms based on visibility campaigns. They choose based on capability, trust, and network strength.
One thing that’s silently killing the market
Fee undercutting.
For years, mid-sized firms accepted mandates at unsustainable rates simply to get in the door. That mindset is beginning to shift.
Firms are walking away from mandates where the fee doesn’t justify the regulatory exposure.
As Vikas puts it, without softening: “If you pay peanuts, you’ll only get monkeys.”
The irony is that the Big 4 have their own version of the same problem.
As one Big 4 partner summarised it: “If one Big firm quotes $100 and another quotes $90, the client will just move. Both are trusted names, so price becomes the decider.”
Over time, fees drop, but workload and regulatory expectations keep going up.
Rise in talent mobility
Akshay told us: “Partner hiring and movement across firms has increased significantly, indicating rising competition for sector expertise.”
This is gradually reshaping capability distribution across firms.
Most interesting story…
Consolidations and Alliances are beginning to appear, and Audit rankings may no longer be about individual firms.
For instance, KGS Alliance:
- Kirtane & Pandit (West),
- SS Kothari Mehta (North),
- Guru & Jana (South)
They’re pooling technology subscriptions, databases, and talent pipelines.
On a combined basis, SS Kothari + Kirtane & Pandit, we’re auditing close to 70+ listed entities.
PwC = 75 listed audits (FY24–25)
Thanks to Alliances, Large Indian firms are getting closer to the Big 4/6.

So, who wins Audit rotation 2.0?
Audit is still a brand market….The Big 4 and broader Big 6 are expected to retain dominance.
Estimates suggest that 10% of mandates may move outside this Big 4/6 ecosystem.
Good quality companies will upgrade to the Big 4. Firms outside that circle will move between the next 3–4 firms, the top Indian firms.
The real beneficiaries are not random firms. It is a small set of Top mid-sized firms that are aggressive, visible, and already positioned for listed company work
Audit Rotation 2.0 is not a reset. It is a gradual rebalancing.
- Top Indian firms move closer to Big 4/6 positioning
- Mid-tier firms absorb spillover mandates.
- Smaller firms face increasing pressure.
Yes, Indian audit firms today are stronger than a decade ago, better capitalised, better staffed, and more networked. But the barriers to entry at the top remain largely unchanged.
