Company Secretary vs CA: What Is the Difference? (2026 Guide)

Last Updated: March 2026 | Reading Time: 11 minutes

One of the most common questions I hear from startup founders and business owners is: “Do I need a Company Secretary or a Chartered Accountant—or both?” The confusion is understandable. Both titles contain “chartered” or “professional” language, both are regulated professionals in India, and sometimes their work overlaps. But their qualifications, responsibilities, and expertise are fundamentally different.

This misunderstanding has cost companies dearly. I’ve seen companies hire only a CA, miss critical governance deadlines, and face director disqualification. I’ve also seen companies hire only a CS, struggle with tax planning, and overpay on their tax liability. The truth is, most growing companies benefit from both—but you need to understand what each does.

In this guide, I’ll break down exactly what separates these two professions, when you need each one, and how they should work together for optimal compliance and governance.

Head-to-Head Comparison: Company Secretary vs Chartered Accountant

Understanding Company Secretaries (CS): The Governance Backbone

What Does a Company Secretary Do?

A Company Secretary is essentially the governance officer of a company. Think of them as the guardian of corporate compliance, board processes, and regulatory adherence. Under the Companies Act, 2013, a CS is responsible for:

• Board Administration: Organizing board meetings, maintaining board minutes, ensuring proper meeting processes, and documenting board resolutions
• ROC Filings: Preparing and filing all statutory forms with the Registrar of Companies—Annual Returns (MGT-7), change forms (DIR-12, DIN-2), and other regulatory documents
• Regulatory Compliance: Ensuring the company complies with Companies Act, SEBI regulations (if listed), MCA directives, and industry-specific rules
• Shareholder Matters: Managing shareholding records, dividend distributions, share transfers, and AGM/EGM processes
• Director Management: Maintaining director databases, managing DIN (Director Identification Number) registrations, tracking director disqualifications
• Insider Trading Compliance: For listed companies, monitoring insider trading policies and code of conduct compliance
• Secretarial Audit: Conducting annual secretarial audits (Form MR-3) to report on governance compliance to shareholders
• Contract Management: Maintaining company contracts, overseeing contractual compliance, and document retention

What Qualifications Do Company Secretaries Have?

To become a Company Secretary in India, a candidate must:

1. Complete 12th standard
2. Pursue a Bachelor’s degree (any stream)
3. Complete the ICSI CS (Company Secretary) course, which includes Foundation, Intermediate, and Final levels
4. Complete a mandatory 6-month internship
5. Pass the Final examination

The entire process typically takes 4.5–5 years. Upon qualification, a CS must register with the ICSI and adhere to the ICSI Code of Conduct and Ethics.

Which Companies Are Required to Have a Company Secretary?

Under Section 203 of the Companies Act, 2013:

• Mandatory whole-time Company Secretary: All listed companies + all unlisted companies with paid-up capital ≥ ₹5 crore
• Optional: All other companies (private companies with < ₹5 crore paid-up capital can choose to appoint a CS, but it's not mandatory)

However, even if your company isn’t legally required to have a whole-time CS, you should still engage a CS for specific functions like secretarial audits, ROC filings, and board administration.

Understanding Chartered Accountants (CA): The Financial & Tax Specialists

What Does a Chartered Accountant Do?

A Chartered Accountant is primarily a financial and tax professional. Their core responsibilities include:

• Financial Accounting: Preparing, reviewing, and certifying financial statements according to Indian Accounting Standards (IndAS) or Generally Accepted Accounting Principles (GAAP)
• Statutory Audit: Conducting annual audits and issuing audit reports (Form ADT-1) attesting to the accuracy of financial statements
• Tax Planning & Compliance: Filing income tax returns, GST returns, calculating tax liability, and identifying tax-saving opportunities
• Payroll & HR Compliance: Managing salary structures, statutory deductions, PF/ESI contributions, and compliance with labor laws
• Financial Advisory: Advising on capital structure, fundraising strategies, acquisition pricing, and financial projections
• Insolvency Matters: Acting as insolvency practitioners in bankruptcy proceedings
• Internal Audit: Reviewing internal controls, financial processes, and fraud detection
• GST Compliance: Managing Goods and Services Tax filings, input credit optimization, and GST audits
• Attestation Services: Providing certifications for bank loans, foreign remittances, and regulatory bodies

What Qualifications Do Chartered Accountants Have?

To become a Chartered Accountant in India, a candidate must:

1. Complete 12th standard
2. Pursue a Bachelor’s degree (any stream)
3. Complete the ICAI CA course, which includes Foundation, Intermediate, and Final levels
4. Complete a mandatory 3-year articled assistant period (practical training)
5. Pass the Final examination

The total timeline is typically 4.5–5 years, similar to CS qualification but with emphasis on accounting and auditing standards.

Which Companies Must Have a Chartered Accountant?

Unlike CS requirements, there’s no legal mandate for all companies to have a CA. However, CAs are practically essential for:

• All companies required to conduct statutory audits (typically those with turnover > ₹1 crore or paid-up capital > ₹2 crore)
• Any company filing GST or income tax returns
• Companies seeking bank loans or external funding
• Listed companies and public sector undertakings

Most operating companies engage a CA for basic tax and accounting compliance, even if not legally required.

The Critical Differences: What Each Can and Cannot Do

Taxation and Financial Reporting

Only a CA can:

• File income tax returns and provide tax advisory
• Conduct statutory audits and sign audit reports
• Manage GST compliance and filings
• Provide financial statement certifications

A CS cannot do these—it’s outside their scope. Even if a CS understands how taxes affect the company, they cannot legally prepare tax returns or file them as the responsible professional.

Corporate Governance and ROC Compliance

Only a CS can:

• Conduct secretarial audits (Form MR-3)
• Sign and file director change forms (DIR-12)
• File annual returns and MOA/AOA changes
• Manage board administration and governance documentation
• File insider trading policies and related filings

A CA cannot do these—it’s outside their professional scope. Many companies have discovered this the hard way when the MCA rejected a filing because it wasn’t signed by a qualified CS.

The Gray Area: Financial Compliance in Annual Returns

Here’s where it gets tricky. The Annual Return (Form MGT-7) includes financial information. Both CSs and CAs are involved, but in different ways:

• CA prepares the financial statements (AOC-4 form) and audits them (ADT-1 form)
• CS files the Annual Return (MGT-7 form) and ensures governance compliance details are accurate

They need to coordinate because the financial data in MGT-7 must match the audited financials. But the CA doesn’t file the MGT-7—the CS does.

When You Need a Company Secretary vs a Chartered Accountant

You Definitely Need a CS If:

• Your company is listed on NSE/BSE—secretarial audit is mandatory, and SEBI LODR requirements are extensive
• Your paid-up capital is ≥ ₹5 crore—you’re legally required to have a whole-time CS
• You have complex shareholding—multiple classes of shares, investor classes, or frequent share transfers
• You’re planning fundraising or M&A—investors will demand a compliance certificate from a qualified CS
• You operate in regulated sectors—pharma, finance, insurance, and other sectors require secretarial audits
• You’ve had compliance issues—missed ROC filings or director disqualifications—hiring a CS protects you going forward
• You have multiple subsidiaries or group companies—governance complexity increases dramatically

You Definitely Need a CA If:

• Your annual turnover exceeds ₹1 crore—statutory audit becomes mandatory
• You file GST returns—you need a CA for GST compliance and filing
• You need bank loans or credit facilities—lenders require CA-audited financial statements
• You have employees—you need payroll tax compliance managed by a CA
• You’re planning acquisition or exit—due diligence requires detailed financial audits
• You want to minimize tax liability—tax planning requires CA expertise
• You handle foreign remittances—CAs manage foreign exchange compliance (Form 15CA/15CB)

You Need Both If You’re:

• A listed company with ₹5+ crore paid-up capital
• A high-growth startup raising funds (investors require both governance and financial audits)
• A mid-size company with turnover > ₹10 crore and paid-up capital > ₹2 crore
• A private company planning an IPO
• Any company with historical compliance issues

How Company Secretaries and CAs Work Together

The most effective governance structure involves CS and CA collaboration:

Example Timeline (Annual Compliance Cycle):

1. January–February: CA prepares draft financial statements, CS prepares board papers
2. March 15–31: Board meeting approves financial statements and Annual Report, CA conducts audit, CS prepares MGT-7 draft
3. April: CA files AOC-4 (financial statements) and ADT-1 (audit report), CS files MGT-7 (annual return)
4. May–June: AGM held, CS files AGM minutes, both prepare for any shareholder directives
5. July–December: Both monitor compliance, handle changes (CS files director changes), prepare for next cycle

Without this coordination:

• Numbers in financial statements won’t match MGT-7, causing filing rejections
• Audit delays cause MGT-7 filing delays (₹500+/day penalty)
• Tax planning opportunities are missed because CS and CA didn’t coordinate
• Governance issues get overlooked because finance focus is on numbers only

Common Mistakes Companies Make

Mistake #1: Hiring Only a CA, Skipping the CS

Many small companies think: “Our CA handles everything—why do we need a CS too?”

Reality: Your CA will miss ROC compliance deadlines, MGT-7 filings, director change forms, and secretarial audit requirements. The MCA doesn’t care that your financial numbers are correct—if your MGT-7 is late, you get a penalty. I’ve seen startup founders get personally liable for ₹5,00,000+ in accumulated penalties simply because they skipped the CS part of compliance.

Mistake #2: Hiring Only a CS, Skipping the CA

Some companies with < ₹1 crore turnover think: "We're too small for an audit, so we just need a CS."

Reality: Without a CA, you’re not managing tax liability optimally, missing GST compliance opportunities, and risk income tax scrutiny. If you ever need to raise funding, acquire a company, or take a loan, the absence of audited financials becomes a blocker. Additionally, you’re at higher risk of tax notices.

Mistake #3: Not Verifying Qualifications

Some companies hire professionals who claim to be “CS” or “CA” without verifying their registration.

Reality: Always check ICSI member directory (for CS) or ICAI member list (for CA). Engaging an unqualified person for regulated work makes your company liable for penalties. The MCA rejects filings if they’re not signed by a properly registered CS.

Cost Comparison: CS vs CA vs Both

Annual Professional Fees (Bangalore, 2026):

• Outsourced CS Services Only: ₹20,000–₹60,000/year (for ROC filings and board admin)
• Outsourced CA Services Only: ₹25,000–₹1,50,000/year (for audit and tax)
• Both CS + CA: ₹50,000–₹2,00,000/year (depending on company complexity)
• Whole-time CS (In-house): ₹8–₹25 lakhs/year (salary + benefits), required for ₹5+ crore paid-up capital
• Whole-time CA (In-house): ₹10–₹30 lakhs/year (salary + benefits), typical for mid-size companies

Value Perspective: The cost of both professionals combined is significantly less than the cost of non-compliance penalties. A single serious ROC filing miss can cost ₹2+ lakhs in penalties alone. Over a 3-year period, having qualified professionals costs less than one major compliance failure.

FAQ: Company Secretary vs Chartered Accountant

Q1: Can a Company Secretary prepare my income tax return?

A: No. Only a Chartered Accountant can legally prepare and file income tax returns. A CS can understand tax implications of corporate decisions, but cannot act as the responsible professional for tax filing. Using an unqualified CS for tax work exposes you to income tax penalties and e-filing rejection.

Q2: Can a Chartered Accountant file my ROC forms like DIR-12 or MGT-7?

A: No. Only a qualified Company Secretary can sign and file these forms. If your CA has company-law expertise, they can prepare the documents, but a CS must review and file them with the ROC. I’ve seen the MCA reject filings signed by CAs for director appointments, causing MGT-7 filing delays.

Q3: Do I need both a CS and CA if I’m a small private company with ₹50 lakh turnover?

A: Legally, you don’t need either one. However, you need at minimum a qualified accountant handling bookkeeping and tax compliance (CA work). For ROC filings, you can either engage a CS part-time or use a compliance service. Most small companies use a CA for accounting/tax and outsource ROC compliance to a CS service provider.

Q4: What if I hire a CS but they don’t understand finance—can they still file forms?

A: Yes, a qualified CS can file governance-related forms even if they’re not a financial expert. However, a good CS should at minimum understand financial statements enough to identify red flags in MGT-7 filings. Many small firms outsource secretarial work to junior CSs under senior CS supervision, which is efficient and cost-effective.

Q5: Can a single person be both a CS and CA?

A: No. The ICSI and ICAI are separate institutes with separate qualification pathways. You cannot be a dual member. However, there are accounting professionals who hold both qualifications (they did both courses separately), but these are rare and typically work as dual practitioners for large companies.

Q6: What happens if my company files ROC forms without a qualified CS signing them?

A: The MCA will reject the filing, or if it’s accepted without proper authorization, it could be invalidated later. This invalidation can have serious consequences—board decisions may be deemed improper, shareholding changes may be questioned, and you may face penalties. Always ensure a registered CS signs governance-related filings.

Final Thoughts: Building Your Governance Team

As a Company Secretary, I’m biased toward governance and compliance. But honestly, you need both professionals. Here’s the framework I recommend:

If you’re a startup (Seed to Series A):
Outsource to a CA for accounting/tax + engage a CS through a service firm for ROC compliance. Total cost: ₹40,000–₹80,000/year for services.

If you’re growing (₹1–₹10 crore turnover):
Hire a full-time accountant (non-CA), engage a CA for audit and tax planning, and hire a CS part-time or through a service for governance. Cost: ₹60,000–₹1,50,000/year external + 1 internal staff.

If you’re scaling (₹10+ crore or seeking funding):
Hire a full-time CFO or accounting manager, a full-time CA, and a full-time CS (or 2 CSs if multi-subsidiary). This is non-negotiable for investor confidence.

The CS and CA should communicate monthly—no surprises at year-end. This prevents filing misses, optimizes tax planning, and ensures governance aligns with financial strategy.
