See, first of all, let’s clear up one doubt: It is not just the everyday tax filing that CA firms deal with; if they’re a reputable one or one of the biggest ones in the country, then sure enough, they handle all things accounting-related as well as things like billion-dollar mergers and everything in between. And thankfully, there are quite literally so many CA firms that are keeping up the good work and pulling off the stress from people’s shoulders who just need help with these things. So, for whatever reason, you wanted to know about the best ones in the country, then what if we talk about the Top 10 Biggest CA Firms in India 2025? Here we go then.
1. Deloitte India
You most likely expected this company to be first, and it really is. In fact, Deloitte India has succeeded in keeping its #1 position in 2025; thus, it is still the leading CA firm in the country. With the world’s largest accounting network, the Indian branch of Deloitte is present in 13 major cities and is a real BIG name with over 15,000 professionals. Deloitte is on fire in the CA field. They are basically doing all the heavy lifting in the most interesting projects across industries like telecom, energy, and infrastructure, ranging from auditing and tax to risk advisory and consulting.
2. PwC India
There aren’t a lot of companies that can pride themselves on a history that goes way back to the 1800s. This one does, though! PwC India, ranking at the runner-up position, is a combination of both tradition and size. As of 2025, well, with its presence spanning more than 13 cities, it serves the leading ones in the tech, FMCG, energy, and healthcare sectors. It’ll all sound like jargon or a cliche at first, but the thing is, one of the ways that PwC is able to do even in 2025 is to stay relevant through its continuous evolution, particularly with the increasing investments in sustainability consulting and the advisory support for the startup ecosystem in India.
3. EY (Ernst & Young) India
And next, well, EY, ranked third on our list, is still delivering first-class services in areas like taxation, audit, advisory, and, to a lesser extent, very rapidly developing areas such as ESG, international tax, and tech consulting. That’s pretty much so many recommendations are out there, and experts are never tired of saying that by 2025, EY will be the company that everyone turns to when they need help in M&A deals across borders, want to extend their businesses globally, or find green sources of financing.
4. KPMG India
KPMG, although it came into India only in 1993, has managed very well to be ranked fourth this year. KPMG is different from the others by its emphasis on the use of digital technologies for transformation in auditing as well as compliance, which is a thing of utmost necessity in the Indian market presently. Being a well-balanced client base of corporate giants and startups, KPMG is still increasing its value by quick adaptation and talent training through strong CA programs out there.
5. Grant Thornton Bharat LLP
Number five on our list is a name that has made massive progress in a very short period of time. How and why? Well, just to give you an idea, in less than a year, Grant Thornton Bharat has undergone exponential growth across 13 cities and now caters to more than 3,500 professionals. Their deeper focus on mid-sized and fast-growing companies, especially in M&A, ESG advisory, and financial planning, is what really worked in their favor, pretty much.
6. BDO India
Compared to some others, BDO India is not that old. But still, it is 100% true that it does have a strong impact. BDO, which is the local face of the fifth-largest global accounting network, is ranked as number six on our list. In fact, it has spread its roots well in a total of 12 cities across India. BDO is recognized as a leader in audit, tax, payroll, and transfer pricing, and it caters to clients in India as well as worldwide as of 2025. They focus a lot on the analytical side of things, and for that, they rely on advanced tech solutions, which a lot of mid-sized businesses like about this very company.
7. RSM India
RSM India may not be the most glamorous, but it is definitely one of the fastest-growing firms in the country, and it is ranked seventh on our list. RSM has been expanding gradually in the areas of tax, audit, and risk advisory with a headcount of over 3,000 professionals. When it comes to regulatory compliance, internal audits, and data-driven reporting, it is the tool that shines the brightest, and that’s the best bit about it all.
8. Lodha & Co.
Going back as far as 1941, Lodha & Co. is the oldest firm on this list by quite a margin, and it is ranked #8 on the list. They’re a BIG name down there in metropolises such as Mumbai, Delhi, Kolkata, and Chennai, and are known for delivering excellent services in audit, tax, and consulting. And very much in the same manner, until the year 2025, Lodha & Co. hasn’t given up on its transformation journey, even though it acknowledges very well that there’s quite a lot of competition out there.
9. Luthra & Luthra LLP
Founded in 1979, Luthra & Luthra is ranked ninth but is a very powerful firm nevertheless. How do we know? Oh, well, spread across Delhi, Mumbai, Hyderabad, and Bengaluru with their offices, they have achieved their prominence in the areas of corporate tax advisory, IFRS consulting, and internal audits. This one is not just a choice for clients but for those looking forward to applying for a job.
10. S.S. Kothari Mehta & Co.
At the end of the list, at number ten, there is S.S. Kothari Mehta & Co., a company that has been in the industry for over 50 years, yes, that’s five decades straight. The firm carries a solid reputation in Delhi, Mumbai, and Kolkata and is greatly recognized for its work in statutory audits, taxation, and corporate law. They’re all for those new tech solutions and that’s why the growing startups are loving them.
