The Annual Maintenance of a Hong Kong Company, Explained

At a glance: the four obligations

Deadlines and fees are as published by the Companies Registry and the Inland Revenue Department.

Where the term comes from

Mainland Chinese companies once underwent an “annual inspection”, replaced in 2014 by a simple online annual report — one authority, one filing. Founders used to that system naturally assume Hong Kong has an equivalent single “annual review”.

Hong Kong instead runs several parallel timelines: the Companies Registry handles the annual return, the IRD handles business registration and tax, and the audit is performed by a practising accountant. Agents bundle these under one label because it is easier to sell — but the bundle hides the fact that each item has its own deadline, its own fee and its own penalties.

Obligation 1: the annual return NAR1 — the 42-day window

Within 42 days of the company’s incorporation anniversary each year, an annual return NAR1 goes to the Companies Registry, setting out the company’s current statutory particulars (directors, shareholders, address, share capital). Filed on time the registration fee is HK$105; late, it escalates in steps to HK$3,480 beyond nine months, and the company and its directors may be prosecuted.

Two things to note: the deadline runs from the incorporation date, not your financial year end or tax deadline; and it is not a tax return — a private company attaches no financial statements. The full breakdown is in the NAR1 guide.

Obligation 2: business registration renewal — annually, with the IRD

The business registration certificate expires and is typically renewed each year. For 2026-27 a 1-year certificate costs HK$2,350 (HK$2,200 fee + HK$150 levy). The IRD posts a demand note to the registered address about a month before the new certificate starts; if it does not arrive, the company must notify the IRD in writing within 1 month of the old certificate expiring. The fee breakdown and the 1-year vs 3-year choice are in the business registration renewal guide.

Obligation 3: bookkeeping, audit and the tax return — the heavy one

This is the largest of the four in both effort and cost, and the biggest difference from the mainland system:

• Bookkeeping: the year’s transactions, bank statements and receipts compiled into financial statements
• Statutory audit: every Hong Kong limited company, whatever its size, must have its annual financial statements audited by a Hong Kong practising accountant — there is no small-company audit exemption like the mainland’s, as explained in the audit requirements guide
• Profits tax return: filed with the IRD together with the audit report; tax is charged on two tiers — 8.25% on the first HK$2,000,000 of profits, 16.5% above that

A new company’s first profits tax return is generally issued about 18 months after incorporation; after that, returns are issued around April each year. What to prepare the first time is covered in the first tax filing guide.

Obligation 4: registered address and company secretary — all year round

A Hong Kong company must continuously maintain a Hong Kong registered address and a qualified company secretary (the sole director of a one-person company cannot double as secretary). Both usually renew annually with a service provider — and letting them lapse undermines the other three obligations, because every government letter, from tax returns to demand notes, goes to the registered address. A dead address means no deadline ever reaches you.

The three most common misconceptions

Misconception 1: it is one filing at one department. It is two departments and at least three timelines: the annual return follows the incorporation date, business registration follows the certificate’s expiry, and tax follows your year end. Each runs its own penalty clock, and the departments do not remind each other.

Misconception 2: it works like the mainland’s annual report. The mainland’s is a free self-service online filing; Hong Kong’s defining difference is that the audit must be performed by a practising accountant — real work, real fees, and books that need to be in order well before the deadline.

Misconception 3: no business means nothing to do. No operations, no income, no bank movements — the annual return is still due, business registration still renews, and a tax return issued must still be filed. Formally exempting a company requires applying for dormant status through the Companies Registry; it is not automatic, as covered in what to do when a company stops operating.

What does a year actually cost?

The fixed government fees are modest. The real cost centre is bookkeeping and audit, which scale with transaction volume — which is why “how much does annual maintenance cost” has no single answer online. Quotes that name one flat price usually cover only the government fees and the filing, not the audit.

The timeline: two anchors, not one date

A Hong Kong company’s annual obligations hang on two different anchors:

• The incorporation anniversary: the annual return (42 days after it); a local company’s first business registration certificate also runs from the incorporation date, so renewals generally track the incorporation month
• The financial year end: sets the audit cycle and the tax filing deadline — and since the year end is yours to choose, choosing well can legitimately buy more preparation time, as explained in choosing a financial year end

For most companies the two anchors fall in different months. Track only one, and the other timeline will eventually slip.

Rather not track four timelines yourself?
