Who checks the accounts? Mostly not the big four.
An auditor is the outside firm that checks a company's accounts. Each dot is one company: 5,186 in all.
The check on 8 October 2026 did not pass this chart’s own data test, so it was not redrawn. The figures below are as of 30 September 2026.
What the chart shows
About 1 in 10 of India's listed companies has its accounts checked by one of the big four audit firms (Deloitte, EY, KPMG, PwC). Of 5,186 companies, 548 name one of them as auditor in their latest results; the other 4,638 are checked by over 2,000 other firms.
The big four (companies whose latest results name them)
| EY | 179 companies (in India it signs as S.R. Batliboi & Co, S.R. Batliboi & Associates and S R B C & Co) |
|---|---|
| KPMG | 159 companies (in India it signs as B S R & Co and B S R & Associates) |
| Deloitte | 127 companies (in India it signs as Deloitte Haskins & Sells) |
| PwC | 83 companies (in India it signs as the Price Waterhouse firms) |
| Together | 548 companies (10.6%). One company names two of the four; it is counted once, under the first one named. |
Everyone else
- 4,638 companies, checked by over 2,000 other audit firms. The ones named most often: Walker Chandiok & Co (123 companies) and M S K A & Associates (84). About 1,200 of the firms check just one listed company.
Some companies, many of them banks, have two or more auditors working together. A company counts under the big four if any one of them is.
What this is: the audit firm named in each company's latest results filing. What it is not: a judgement of any firm or company. It says nothing about how good any audit is.
How it is measured
Every listed company must have its yearly accounts checked by an outside audit firm (its statutory auditor), and its results filings name that firm. This counts the firm named in each active company's latest results filing whose period ended from March 2025 to June 2026 (the 18 months before 30 September 2026); 5,186 companies name one. 4,946 of them (95%) are read from a period that ended in the last 12 months. Firm names are written many ways in the filings ("B S R & Co.
LLP", "BSR and Co", "M/s. B S R & Co., LLP"), so each name is tidied (the "M/s" prefix, punctuation, "LLP", "Chartered Accountants" and registration numbers removed) and matched on its letters. The big four work in India through Indian firms, and that is the name on the filing: EY as S.R. Batliboi & Co, S.R. Batliboi & Associates and S R B C & Co; KPMG as B S R & Co and B S R & Associates; Deloitte as Deloitte Haskins & Sells; PwC as the Price Waterhouse firms.
Similar-looking names that are not these firms (Batliboi & Purohit, R.G.N. Price & Co) are not counted as big four. Some companies have two or more auditors working together (joint auditors, common at banks and government companies): 147 companies here, 25 of them with a big-four firm among their auditors. A company counts as big four when any of its auditors is one. 1 company names two of the four; it is drawn once, under the first named.
Firms are counted by name after merging names that differ by one letter (a typo) or only by a missing "& Co": about 2,059 other firms (2,139 before merging), printed as "over 2,000". Left out: 128 active companies with a results filing in the window but no auditor name in it, 133 companies no longer active, and 18 auditor entries that were not a name ("NA", "0", a registration number). This counts whose name is on the filing. It says nothing about the quality of any audit, any audit firm or any company, and a bigger firm is not a better or worse auditor.
