Hong Kong Limited Company Tax Filing

Hong Kong Limited Company Tax Filing

Does the pile of documents for year-end tax filing and audit feel overwhelming? Tax filing is a statutory responsibility for Hong Kong limited companies. Beyond completing the BIR51 return, you must engage a licensed auditor to prepare an audit report—this is a step you cannot skip.

Many business owners assume that a company without profits can ignore tax filing. In fact, it must still submit the return and apply for exemption on time or risk penalties from the Inland Revenue Department. Engaging a professional team lets you focus on growing your business without worrying about tax matters.
M&N Business Services arranges tax filing and audits for Hong Kong SMEs, providing one-stop support from organising documents to submitting reports. We also help you make use of two-tiered profits tax rates and available allowances to maximise lawful savings. Let us make tax filing easier for you.

Hong Kong Limited Company Tax Filing Process

Hong Kong limited company tax filing follows a statutory process. M&N sets out the steps clearly:
Bookkeeping: keep bank statements, invoices, receipts and other business records properly for at least 7 years.
Financial statements: prepare a balance sheet and income statement in accordance with Hong Kong Financial Reporting Standards.

Audit: appoint a Hong Kong licensed auditor to conduct the audit and issue an auditor’s report, as required by law.

Tax return submission: complete the Profits Tax Return (BIR51) and submit it with the audit report to the Inland Revenue Department.

Assessment and payment: the Inland Revenue Department issues an assessment, and the company pays its tax and provisional tax on time.

Hong Kong Limited Company Tax Filing FAQs

Even if the company has not started operating, it must submit any tax return received from the Inland Revenue Department on time, stating that business has not commenced. Many owners mistakenly believe no filing is needed and subsequently receive penalty notices.

An audit is particularly important when the company makes a loss. It is required by law, and losses recorded in the audit report can be carried forward to reduce tax in a later year. M&N helps you make use of this benefit.

A nil return is suitable only for a company with no bank account and no business records at all. If your company has paid wages, received money from clients or even paid rent, filing a nil return can create problems and make an Inland Revenue Department review more likely.

It can reduce tax, but the process involves more than filling in a form. You need sufficient evidence to demonstrate to the Inland Revenue Department that your business and profits are genuinely unrelated to Hong Kong. M&N has helped many clients apply successfully and understands the review requirements.

Keep all documents relating to company income and expenditure, including bank statements, sales and purchase contracts, payroll records, invoices and receipts. M&N provides a clear checklist and guidance on organising these records.

We do more than complete forms and submit figures: we act as your tax partner. We proactively remind you of deadlines and explain how everyday business arrangements can support lawful tax savings, helping you save time and money.
