APR audit for a UK Ltd owned by an Indian company — FRS 102, Companies House timing, and the December 31 mismatch

If your Indian company owns a UK Private Limited (Ltd) company, you face a unique compliance challenge: managing two different regulatory frameworks — the RBI's APR filing requirements in India and the UK's Companies House obligations — that often operate on completely different financial year timelines. This guide covers everything you need to know about APR audit for a UK subsidiary, including FRS 102, the December 31 year-end mismatch, and why a qualified UK auditor for APR filing is non-negotiable.

What Is APR Filing and Who Needs to File It?

APR stands for Annual Performance Report. It is a mandatory annual filing required by the Reserve Bank of India (RBI) under the Foreign Exchange Management Act (FEMA) for every Indian entity that has made an Overseas Direct Investment (ODI). Whether your UK subsidiary is a small startup or a growing operational entity, FEMA compliance requires you to file an APR every year — no exceptions.

APR filing India is submitted through your Authorised Dealer (AD) Bank and must include certified audited financial statements of the overseas entity. This is where most Indian companies with UK subsidiaries run into difficulty — the RBI's financial year ends on March 31, while most UK companies follow a December 31 or April 5 financial year end. This mismatch creates a timing problem that must be carefully managed to stay within overseas investment compliance requirements.

The December 31 Mismatch: Why It Creates a Problem

Most UK Ltd companies register with a financial year ending December 31. Under UK law, these companies have nine months from their financial year end to file accounts with Companies House — meaning accounts for the year ended December 31 are not due at Companies House until September 30 of the following year.

However, the RBI's APR filing deadline is July 31 each year, covering the Indian financial year ending March 31. This means that when you sit down to prepare your APR in April, May, or June, your UK subsidiary's audited accounts for the year ended December 31 may not yet be finalised — let alone filed with Companies House.

This is the December 31 mismatch, and it is one of the most common causes of delayed or defective APR filing for foreign subsidiaries with UK operations. The solution is not to skip the audit — it is to proactively commission the audit of your UK subsidiary well before the Companies House deadline so that certified accounts are available for RBI reporting requirements by July 31.

FRS 102: The Accounting Standard Your UK Subsidiary Must Follow

All UK Ltd companies preparing statutory accounts must comply with UK Generally Accepted Accounting Practice. For the vast majority of UK subsidiaries owned by Indian companies, the applicable standard is FRS 102 — the Financial Reporting Standard applicable in the UK and Republic of Ireland.

FRS 102 is a comprehensive accounting framework that governs how income, expenses, assets, liabilities, and equity are recognised and disclosed in the financial statements. It is broadly comparable to IFRS but with important differences, particularly around lease accounting, financial instruments, and revenue recognition. When a UK auditor for APR filing certifies your subsidiary's accounts, those accounts must be prepared in accordance with FRS 102 and audited under UK auditing standards (ISAs UK).

For the purposes of foreign subsidiary audit compliance and APR filing, the RBI accepts audited accounts prepared under the local accounting standards of the country of incorporation. FRS 102 accounts certified by a registered UK auditor fully satisfy this requirement — provided the audit is completed and the accounts are signed before the APR submission deadline.

Who Can Audit a UK Ltd for APR Filing Purposes?

The RBI requires that audited accounts of an overseas subsidiary be certified by a Chartered Accountant or an equivalent professional in the jurisdiction of incorporation. For a UK Ltd company, this means the accounts must be audited by a UK-registered statutory auditor — typically a member of the Institute of Chartered Accountants in England and Wales (ICAEW), the Institute of Chartered Accountants of Scotland (ICAS), or another recognised supervisory body under the Companies Act 2006.

An Indian CA cannot audit a UK company for RBI purposes. A UK auditor for APR filing is mandatory. This is not a technicality — it is a fundamental requirement of foreign investment reporting under FEMA. The overseas subsidiary audit must be performed by a professional authorised to conduct statutory audits in the UK.

It is worth noting that under UK law, small companies that meet two of the three size thresholds (turnover below £10.2 million, balance sheet below £5.1 million, fewer than 50 employees) are exempt from mandatory statutory audit. However, even if your UK subsidiary qualifies for audit exemption under UK law, you must still commission a voluntary audit to meet the RBI's APR requirements. This is a crucial distinction that many Indian entrepreneurs miss when managing annual compliance for foreign subsidiaries.

Step-by-Step: Managing APR Audit Compliance for a UK Subsidiary

Here is the practical process for ensuring your UK Ltd meets both RBI and UK regulatory obligations on time:

• Appoint a registered UK statutory auditor early — ideally within the first quarter after your UK subsidiary's financial year end (January to March for a December 31 year-end company).

• Ensure your UK company's books are properly maintained throughout the year under FRS 102, so the auditor has accurate records to work from.

• Request that the audit be completed and signed by May or June at the latest, well ahead of both the July 31 APR deadline and the September 30 Companies House filing deadline.

• Obtain the signed audited financial statements from the UK auditor — these form the primary supporting document for your APR filing India submission.

• Prepare and submit the APR through your AD Bank, attaching the UK-audited accounts as the mandatory enclosure.

• File the same audited accounts with Companies House by the September 30 deadline to complete your UK regulatory obligations.

• Retain all audit reports, APR acknowledgements, and bank correspondence for five years for FEMA compliance records.

ODI Compliance: What the RBI Actually Checks in the APR

Beyond the audit requirement, the APR itself is a substantive compliance document. The RBI uses the APR to monitor the performance of Indian companies' overseas investments. The form requires disclosure of the UK subsidiary's financial performance, details of any further investments made during the year, remittances received from the subsidiary, and confirmation that the subsidiary is operating within the scope of the original ODI approval.

ODI compliance failures — including late filing, incorrect disclosures, or missing audited accounts — are treated seriously under FEMA. Penalties can be levied on both the Indian company and its directors. In cases of persistent non-compliance, the RBI can also restrict the company from making further overseas investments, which can severely hamper international growth plans.

Subsidiary compliance reporting is therefore not a back-office task — it is a strategic obligation that needs dedicated attention from finance and legal teams every year.

Common Mistakes Indian Companies Make with UK Subsidiary APR Filing

• Waiting too long to appoint a UK auditor: Starting the audit process in June leaves no room to meet the July 31 APR deadline if issues arise.

• Assuming audit exemption means no audit needed: UK small company audit exemption does not override the RBI's audit requirement for overseas investment compliance.

• Confusing the Companies House deadline with the RBI deadline: The September 30 Companies House deadline is months after the July 31 APR deadline — do not use the former as your planning target.

• Using unaudited management accounts for the APR: The RBI requires certified audited accounts, not management accounts or internally prepared statements.

• Not coordinating between the UK auditor and the Indian CA: The two advisors must work together to ensure the audited financials are formatted correctly for RBI submission while also complying with UK filing requirements.

Choosing the Right UK Auditor for APR Filing

Not every UK accounting firm has experience with the specific needs of Indian-owned subsidiaries. When selecting a UK auditor for APR filing, look for firms that understand the RBI's documentation requirements, have worked with Indian parent companies before, and can deliver signed accounts within the tighter timeline required by the July 31 APR deadline rather than the more relaxed Companies House schedule.

Equally important is ensuring your Indian CA or compliance advisor is involved in the process. The UK auditor handles the foreign subsidiary audit compliance on the UK side; your Indian advisor coordinates the APR submission and ensures the supporting documents meet the AD Bank's requirements. International business compliance works best when both sides of the relationship are professionally managed and well coordinated.

Conclusion: Get Ahead of the Mismatch, Stay Ahead of the Regulators

The December 31 mismatch between UK company year-ends and India's March 31 financial year is a known, manageable challenge — but only if you plan for it. APR filing for foreign subsidiaries with UK operations requires early action: appointing a qualified UK auditor well before the year-end, ensuring FRS 102-compliant accounts are audit-ready, and getting signed financials in hand months before the July 31 deadline.

The cost of getting this wrong — FEMA penalties, RBI scrutiny, restrictions on future ODI — is far greater than the cost of doing it right. Investing in the right UK auditor for APR filing, coordinating with your Indian CA, and treating overseas subsidiary audit as a priority each year is the foundation of sound international business compliance for any Indian company with a UK presence.
