An audit is more than a yearly formality. For a growing business, the auditor’s report is what banks, investors, tax authorities and future buyers rely on when they decide whether to trust the numbers. Yet many founders are unsure of a basic question: who is allowed to appoint the auditor, by when, and what paperwork follows?
The answer depends on the legal form of the business. A partnership firm, a limited liability partnership (LLP) and a private limited company are each governed by different laws, and each has its own rules on audit. This guide walks through all three in plain terms, so that business owners can stay compliant and avoid penalties that often arise from simple timing mistakes.
Why the Appointment Process Matters
The way an auditor is appointed affects whether the audit itself is valid. An auditor appointed by the wrong body, outside the permitted time, or without the required consent can expose the business to fines, rejected filings and questions from regulators. A correct appointment, on the other hand, gives the audit legal standing and protects both the business and its owners.
There is also a practical side. Appointing the auditor early gives enough time to plan the audit, clean up the books and resolve open issues before deadlines come close. Businesses that leave the appointment to the last few weeks of the year usually end up rushing both the audit and their filings.
Appointment of Auditor in a Private Limited Company
For private companies, auditor appointment is governed by the Companies Act, 2013, and the process is more structured than for firms or LLPs.
The first auditor. Every new company must appoint its first auditor within 30 days of incorporation, and this decision is taken by the Board of Directors. If the Board fails to do so, the responsibility shifts to the shareholders, who must appoint the auditor within 90 days at a general meeting. The first auditor holds office until the end of the company’s first Annual General Meeting (AGM).
Subsequent auditors. At the first AGM, the shareholders appoint an auditor for a term of five years, running until the end of the sixth AGM. Since 2018, there is no longer a need for shareholders to confirm this appointment every year, which has simplified compliance considerably.
Consent and eligibility. Before any appointment, the company must obtain the auditor’s written consent along with a certificate confirming that the auditor is eligible and that the appointment falls within the legal limits. Only a practising Chartered Accountant or a firm of Chartered Accountants can be appointed.
Filing with the Registrar. After the appointment at the AGM, the company must inform the Registrar of Companies by filing Form ADT-1 within 15 days of the meeting. This is a frequent point of failure, and late filing attracts additional fees.
Rotation of auditors. Mandatory rotation, which limits how long the same auditor can continue, applies only to larger private companies that cross prescribed capital or borrowing limits. Most small and mid-sized private companies are not covered, although it is worth checking each year as the business grows.
Vacancies, resignation and removal. If the auditor’s position falls vacant mid-term, the Board can fill it within 30 days. Where the vacancy is caused by resignation, the new appointment must also be approved by shareholders within three months. A resigning auditor files Form ADT-3 within 30 days of resigning. Removing an auditor before the term ends is a serious step: it needs a special resolution of shareholders and prior approval of the Central Government.
Appointment of Auditor in an LLP
LLPs are governed by the Limited Liability Partnership Act, 2008 and the LLP Rules, 2009. Audit is mandatory for most LLPs, with an exemption only for very small LLPs whose turnover and partner contribution both remain within the prescribed limits. Even where an exemption applies, many LLPs choose a voluntary audit because banks and investors ask for one.
Who appoints. The responsibility lies with the designated partners. If the designated partners have the power to appoint but fail to do so, the partners themselves may make the appointment.
Timelines. The first auditor should be appointed early in the life of the LLP, well before the first financial year closes. For every later year, the auditor must be appointed at least 30 days before the financial year ends, which means by 1 March for a 31 March year-end.
Eligibility. Only a Chartered Accountant in practice can be appointed as auditor of an LLP. As with companies, it is good practice to obtain the auditor’s written consent before finalising the appointment.
Fees, resignation and removal. The auditor’s fee may be fixed by the designated partners or as set out in the LLP agreement. If the LLP agreement is silent on removal, removing the auditor requires the consent of all partners. An auditor who does not wish to continue must give written notice at the registered office at least 14 days before the time allowed for appointing a new auditor runs out.
There is no separate form required merely to record the appointment of an LLP auditor. However, the audited accounts flow into the LLP’s annual filings, so a delayed appointment quickly turns into delayed filings and daily late fees.
Appointment of Auditor in a Partnership Firm
A traditional partnership firm, registered under the Partnership Act, 1932, has no general legal requirement to get its accounts audited. In practice, however, many firms need an auditor for one of three reasons.
Tax audit. The most common trigger is the tax audit under income-tax law. The Income-tax Act, 2025 has replaced the Income-tax Act, 1961 with effect from 1 April 2026, and the tax audit provision now sits in Section 63, which largely continues the earlier Section 44AB. A firm whose turnover or gross receipts cross the prescribed limits, or which reports profits below the presumptive rate in certain situations, must get its accounts audited. Under the new law, the audit report is furnished in Form 26, which replaces the earlier Forms 3CA and 3CB.
The partnership deed. Many deeds require an annual audit to protect the interests of all partners, especially where some partners are not involved in day-to-day operations.
Lenders and stakeholders. Banks, investors and large customers often ask for audited accounts, even where the law does not.
How the appointment works. Since there is no prescribed statutory process, the partners appoint the auditor by a resolution or written decision, followed by a formal engagement letter that sets out the scope, fees and timelines. There is no filing with any registrar. The main discipline is timing: the auditor should be engaged well before the tax audit due date so that the books can be finalised and reviewed without pressure.
Practical Points for Every Business
Regardless of legal form, a few habits make the process smoother. Confirm the auditor’s eligibility and independence before appointment, including that they have no business or family relationship that could compromise their judgement. Put the scope, fees and timelines in a clear engagement letter. When changing auditors, allow the new auditor to contact the previous one, which is a professional requirement for Chartered Accountants and helps the new auditor understand any open issues. Finally, keep a simple compliance calendar so that appointment dates, filing deadlines and audit timelines are tracked well in advance.
Frequently Asked Questions
Who appoints the first auditor of a private limited company?
The Board of Directors appoints the first auditor within 30 days of incorporation. If the Board fails, the shareholders must do so within 90 days at a general meeting.
How long can an auditor of a private company hold office?
An auditor appointed at the AGM holds office for five years, until the end of the sixth AGM. They can be re-appointed after that, subject to rotation rules where applicable.
Is Form ADT-1 required for the first auditor?
Practice varies, and many companies file it as a matter of caution. For auditors appointed at the AGM, filing ADT-1 within 15 days is clearly required.
Is audit mandatory for every LLP?
No. Very small LLPs whose turnover and partner contribution both stay within prescribed limits are exempt. All other LLPs must get their accounts audited.
What is the deadline for appointing an LLP auditor?
For years after the first year, the auditor must be appointed at least 30 days before the financial year ends.
Does a partnership firm need an auditor?
Not under partnership law itself. An audit becomes necessary when the firm crosses the tax audit limits, when the partnership deed requires it, or when lenders or investors ask for audited accounts.
Can the same Chartered Accountant do both the statutory audit and tax audit?
Yes. For companies and LLPs, the statutory auditor commonly also carries out the tax audit, which saves time and avoids duplication.
Can an auditor be removed before the end of the term?
Yes, but with safeguards. In a private company, it requires a special resolution and Central Government approval. In an LLP, it follows the LLP agreement, or the consent of all partners if the agreement is silent.
What happens if the auditor resigns mid-year?
In a company, the Board fills the vacancy within 30 days and shareholders approve it within three months; the outgoing auditor files ADT-3. In an LLP, the designated partners appoint a replacement promptly to avoid gaps in compliance.
