Top 10 CA Firms in Delhi: A 2026 Guide to Big 4, Mid-Size & Local Firms

What is a CA firm — and what do they do?

A CA firm is a partnership or LLP of Chartered Accountants licensed by the Institute of Chartered Accountants of India (ICAI) to provide statutory audit, tax, assurance, and advisory services. Indian law restricts statutory audits, tax audits under Section 44AB, and many ROC certifications to ICAI-registered CA firms — which is why every business above a certain size eventually needs one.

A typical CA firm in Delhi handles the following for its clients:

• Statutory audit under the Companies Act, 2013
• Tax audit under Section 44AB of the Income Tax Act
• Internal audit and risk advisory
• Income tax return filing and tax planning
• GST registration, returns, and audits
• ROC filings, annual compliance, and secretarial work
• Bookkeeping, payroll, and outsourced accounting
• Transaction advisory, due diligence, and valuations
• TDS return filing and withholding tax compliance

A growing share of compliance work — especially for startups and SMEs — is now delivered through tech-enabled CA & compliance firms that combine an in-house network of CAs, CSs, and lawyers with a digital client dashboard. We’ve included one such firm in the list below.

How we ranked the top CA firms in Delhi

We did not rank by marketing reach. The shortlist below is built on six public, verifiable signals:

1. ICAI Peer Review certification — the firm holds a current peer review certificate, mandatory for listed-entity audits.
2. NFRA-registered audits — the firm appears on the National Financial Reporting Authority register for public-interest audits.
3. Quality of audit clientele — number of listed companies, banks, insurers, and large unlisted entities audited.
4. Years of practice — minimum 7 years of continuous Delhi-NCR presence, with weighting for firms above 20 years.
5. Service breadth — covers audit, tax, advisory, ROC, and outsourced accounting under one roof.
6. Digital workflow & SME accessibility — for the SME and startup tier specifically, the firm offers a managed compliance experience with online tracking and predictable turnaround.

Note that the “Big 4” firms in the list — Deloitte, PwC, EY, and KPMG — operate in India through Indian network firms (Deloitte Haskins & Sells, Price Waterhouse & Co, S.R. Batliboi & Co, and B S R & Co, respectively). One firm in the list, RegisterKaro, is a tech-enabled CA & compliance platform rather than a traditional audit firm — included specifically to cover the SME/startup compliance segment, which the Big 4 and Indian large firms do not realistically serve.

Top 10 CA firms in Delhi (2026)

Here is the consolidated ranking. Each firm has a strong Delhi-NCR presence and serves a distinct client segment, from listed companies and large MNCs through to startups and SMEs.

If you don’t need a name-brand firm, most SMEs don’t, you’ll typically be better served by a strong mid-size firm in your local area or a tech-enabled compliance firm. We cover both, by neighbourhood and by category, further down. For a managed, end-to-end engagement, explore CA services in Delhi.

Big 4 CA firms in Delhi

The “Big 4”, Deloitte, PwC, EY, and KPMG, collectively audit the majority of India’s listed companies, banks, and large unlisted groups. In Delhi-NCR, they operate through ICAI-registered Indian network firms and concentrate their offices in Gurgaon, with Delhi-city support offices.

1. Deloitte Haskins & Sells LLP (Deloitte)

The Indian arm of Deloitte is consistently among the largest audit firms in Delhi by listed-entity count. Strongest in statutory audit, IFRS/Ind AS conversions, risk advisory, and forensic services. Best fit for: large unlisted groups, IPO-bound companies, banking and financial services.

2. Price Waterhouse & Co Chartered Accountants LLP (PwC)

The PwC India audit network firm. Strong assurance for listed entities, banks, insurers, and large MNCs. Best fit for: companies needing global-network reporting, US GAAP/IFRS dual filings, and large listed-entity audits.

Average ticket size: Big 4 audits in Delhi typically start at ₹15–25 lakh per year for unlisted mid-sized companies and run into several crores for listed entities. They are not realistic for SMEs — for an SME or startup, see the mid-size and tech-enabled firms below.

Top mid-size & tech-enabled CA firms in Delhi

Mid-size and tech-enabled CA firms in Delhi (search volume: 110/month for “mid-size CA firms in Delhi”) sit between the Big 4 and single-partner practices. They typically have 5–50 partners (or, in the case of platform-based firms, an in-house network of 50+ CAs/CSs/lawyers), and serve the upper SME, startup, and mid-market segment that the Big 4 won’t take.

5. Walker Chandiok & Co LLP (Grant Thornton Bharat)

The Indian member firm of Grant Thornton International is one of the deepest non-Big 4 practices in Delhi. Strong in audit, IBC (insolvency) advisory, transaction services, and risk. Headquartered in Connaught Place with offices in Gurgaon and Noida.

6. BDO India LLP

The Indian member firm of BDO Global. Strong in audit, tax, business services, and outsourcing for inbound MNCs. Major Delhi-NCR presence in Gurgaon.

Strongest in: company registration (Pvt Ltd, LLP, OPC, Section 8), GST registration and returns, ROC annual compliance, trademark and IP, ITR filing, and outsourced startup compliance. Best fit for: founders, early-stage startups, D2C brands, SMEs, and inbound MNCs that want a managed compliance operation with online tracking and predictable turnaround, without the cost or scale of a Big 4. CA services in Delhi are delivered through a combination of digital workflow and CA partner sign-off, where the law requires it.

CA firms in Delhi by area

Search demand for “CA firm in [area] Delhi” is split across at least 10 micro-locations. Here is a quick area-by-area summary of where the leading firms cluster.

CA firms in Connaught Place (CP), New Delhi

Connaught Place hosts some of Delhi’s oldest CA firms — the area is the traditional financial-professional belt of the city. Walker Chandiok & Co (Grant Thornton) and Lodha & Co. are among the well-known firms with primary offices in CP. CP is best for clients in financial services, banking, and listed-entity work who need walk-in access to legal and banking counterparties.

CA firms in Nehru Place, New Delhi

Nehru Place is the second-largest commercial cluster in South Delhi and a hub for SME-focused CA firms.

CA firms in Netaji Subhash Place (NSP)

NSP, in North-West Delhi, has emerged as a leading commercial CA hub over the last decade. Mid-size firms like S.S. Kothari Mehta & Co. and T R Chadha & Co LLP have major offices here. NSP is strong for clients in real estate, manufacturing, and SMEs based in West and North-West Delhi.

CA firms in Laxmi Nagar, East Delhi

Laxmi Nagar is the densest cluster of small and individual CA practices in East Delhi, partly because it’s also a major coaching hub for CA students. Most firms here are 1–5 partner practices serving local SMEs, traders, and salaried professionals — ideal for ITR filing, GST compliance, basic audit, and ROC work at a lower cost.

CA firms in South Delhi

South Delhi (Saket, Greater Kailash, Defence Colony, Vasant Kunj) hosts mid-to-large boutique firms catering to HNIs, startups, family offices, and consulting professionals. Sahni Natarajan & Bahl (SNB) is a notable South Delhi-headquartered firm.

CA firms in East Delhi

West Delhi (Janakpuri, Rajouri Garden, Tilak Nagar, Punjabi Bagh) has a healthy concentration of mid-size firms serving manufacturing and trading clients. Many West Delhi firms also serve overflow work for Gurgaon and Dwarka clients.

Best CA firms in Delhi for articleship

Direct answer: For CA articleship in Delhi in 2026, the strongest exposure comes from the Big 4 (Deloitte, PwC, EY, KPMG) and the next tier of Indian large/mid-size firms (Grant Thornton, BDO, Lodha, S.S. Kothari Mehta, Walker Chandiok, and T R Chadha). Big 4 stipends are the highest; mid-size firms offer broader, hands-on exposure.

Big 4 articleship in Delhi: what to expect

• Stipend (indicative, 2026): ₹15,000–₹35,000/month across the three articleship years.
• Work mix: Largely audit-heavy — listed-entity statutory audits, IFC testing, group reporting. Some opportunity to rotate into tax or risk advisory.
• Best for: Students targeting Big 4 placements, banking/finance careers, or US-GAAP/IFRS-heavy roles.

Mid-size firm articleship in Delhi: what to expect

• Stipend (indicative, 2026): ₹3,000–₹15,000/month — but rises sharply with seniority.
• Work mix: Much more diverse — statutory audit, tax audit, GST, ROC, MIS, due diligence, valuations, and direct client interaction from year one.
• Best for: Students who want balanced exposure across audit + tax + ROC, plan to start their own practice, or want to clear CA Final with manageable hours.

How to apply for CA articleship in Delhi

1. Clear CA Foundation and Intermediate (Group 1 minimum).
2. Register on the ICAI’s articleship portal and on each firm’s careers page.
3. Prepare a CV that emphasises CA Inter ranks, Excel/Tally skills, and any audit/accounts internships.
4. Apply 2–3 months before your registration deadline — Big 4 close their windows early.

Services that CA firms in Delhi typically offer

Almost every CA firm in Delhi — from Big 4 to single-partner practices to tech-enabled platforms — offers a similar core menu. The difference is depth, ticket size, and specialisation.

Average CA firm fees in Delhi (2026)

CA firm fees in Delhi vary widely by firm size, work complexity, and the type of engagement. Below are realistic 2026 benchmarks based on ICAI’s recommended scale and market practice — actual quotes will differ.

Reality check: The Big 4 are not realistic for SMEs. A growing Delhi-based business with ₹5–50 crore turnover is best served by a mid-size firm or a tech-enabled compliance firm, both of which deliver the same statutory output at 5–10% of Big 4 cost.

How to choose the right CA firm in Delhi

Walk your shortlist through these six checks before signing an engagement letter:

1. Match firm size to your business size. Don’t engage a Big 4 for a ₹2-crore-turnover business — and don’t engage a single-partner CA for a listed-entity audit.
2. Check ICAI peer review status. Mandatory for any firm signing a listed-entity audit.
3. Ask for an industry reference. A firm that’s audited 50 e-commerce companies is a different animal from one that’s audited 50 manufacturing companies.
4. Clarify partner attention. Ask which partner will sign your audit and how often you’ll meet — at most firms, partner contact-time is the single biggest quality differentiator.
5. Demand a fixed-fee or capped-fee engagement letter. Open-ended hourly arrangements blow up budgets.
6. Test responsiveness. Ask three questions over email before signing. Firms that reply in 24 hours during the sales cycle behave the same way after they’re hired.

CA firms in Delhi NCR (Gurgaon & Noida)

“Delhi NCR” extends the catchment to Gurgaon, Noida, Greater Noida, Faridabad, and Ghaziabad. The Big 4 actually concentrate their largest Indian offices in Gurgaon, not Delhi proper. Walker Chandiok & Co, BDO India, RSM India, and Nexdigm have major Gurgaon and Noida presences. Tech-enabled compliance firms like RegisterKaro serve all of Delhi-NCR digitally with on-ground partner sign-off where the law requires it. For an MNC or PE-backed company headquartered in Cyber City or Noida Sector 62, a Gurgaon/Noida-based Big 4 or Indian large firm is almost always the right answer; for a startup or SME, a tech-enabled firm or Nehru Place/NSP mid-size firm is usually the better fit.
