How Can Hong Kong Companies Plan a Corporate Compliance Calendar?

The 42-day annual return window and the April Profits Tax filing cycle leave a Hong Kong company little room for drift. A Hong Kong compliance calendar pulls every statutory date into one plan you can actually manage.

In this blog, we discuss Hong Kong statutory compliance deadlines and first-year milestones for newly incorporated companies. We also explain how to build a calendar that holds.

What Belongs in a Hong Kong Corporate Compliance Calendar?

A workable calendar tracks Companies Registry and Inland Revenue Department (IRD) filings. It also covers company-law duties such as the Annual General Meeting (AGM) and annual audit.

Obligations in Hong Kong flow from two government bodies and the company's own governance rules. Grouping deadlines by source makes each obligation easier to own, and it shows immediately who must act. The table below summarises typical active private-company duties. Exemptions and company type can change those duties, and tax dates by year-end code depend on applicable extensions.

1. Companies Registry filings

The Companies Registry in Hong Kong administers incorporation records and annual filings. For a local private company, Form NAR1 is generally due within 42 days after the incorporation anniversary. Dormant companies may be exempt, depending on when dormant status takes effect. The on-time fee is HK$105 for the 2026-27 year, and late delivery attracts higher fees. Companies must also notify the Registry within 15 days after records are first kept somewhere other than the registered office address.

2. Inland Revenue Department filings

The Inland Revenue Department (IRD) issues Profits Tax returns in bulk each April, but newly incorporated companies wait until around month 18. The first return must reach the IRD within three months of its issue date. The IRD also administers the Business Registration Certificate, renewed every year or every three years, and the one-month notice of business commencement.

3. Company-law duties under the Companies Ordinance

Under the Companies Ordinance (Cap. 622), the first financial period cannot exceed 18 months. Financial statements generally require an annual audit and are laid before the AGM when one is held. Dormant companies are exempt from audit. A private company that is not a public-company subsidiary generally holds its AGM within 9 months after the accounting reference period ends. Special timing applies to a first period longer than 12 months. Dormant and single-member companies need not hold AGMs, and other companies may dispense with them under the Ordinance.

When Are the 2025/26 Profits Tax Returns Due?

The normal due date depends on the return's issue date; eligible represented companies may receive extensions based on their year-end code.

The 2025/26 year of assessment ran from 1 April 2025 to 31 March 2026; the current 2026/27 year runs from 1 April 2026 to 31 March 2027. For eligible companies under the two-tier rates, profits are taxed at 8.25% on the first HK$2 million and 16.5% above it. The IRD generally requires paper returns within one month of issue. Electronic notices generally allow two months. The year-end code determines an applicable Block Extension Scheme date, not the normal due date.

1. Block Extension Scheme dates for 2025/26

N-code paper returns are due on 4 May 2026, after the 1 May public holiday; no block extension applies. Eligible represented D-code returns are extended to 17 August 2026 on paper or 17 September 2026 if e-filed with the further one-month extension. Eligible represented M-code returns are extended to 16 November 2026 on paper or 16 December 2026 if e-filed with the further extension. Eligible M-code loss cases can obtain a further extension to 1 February 2027. The full comparison appears in the table below.

2. The e-filing further extension

Eligible entities required to e-file may receive a further one-month extension automatically if they notified the IRD before March 2026. Others may need to apply. Voluntary e-filers must apply at least seven working days before the return is otherwise due. The further dates for eligible electronic filings are 4 June 2026 for N codes, 17 September 2026 for D codes and 16 December 2026 for M-code profit cases, with no additional e-filing extension beyond the loss-case deadline.

3. Mandatory e-filing for large MNE groups

From the 2025/26 year of assessment, specified Part 4AA entities of in-scope MNE groups generally must e-file Form BIR51 or BIR52 through the Business Tax Portal or Tax Representative Portal, subject to specified exceptions. The group threshold is annual consolidated revenue of at least EUR 750 million in two of the four preceding fiscal years. Even entities previously exempt from annual filing now receive a Notice to File, while non-resident Form BIR54 returns remain on paper.

Which First-Year Milestones Must a New Company Plan?

Key first-year dates include incorporation, the first financial year end, the first AGM if required, and the first Profits Tax return.

Government charges for a new private company limited by shares total about HK$3,895 when filed electronically: HK$1,545 for incorporation plus HK$2,350 for the one-year Business Registration Certificate at 2026-27 rates. A hard-copy incorporation costs HK$1,720 instead. Founders should begin with a Hong Kong company name search before filing, then use our Hong Kong company incorporation services to lock in the dates that follow.

1. Choose the financial year end early

Companies may fix any date as the year end, and December or March are common choices. The first financial period cannot run beyond 18 months from incorporation. That single choice determines the N, D or M tax code and every deadline attached to it.

2. Notify, register and appoint

A company must tell the IRD within one month of commencing business and maintain its Significant Controllers Register from day one. Directors may appoint the first auditor for the first financial year, including when no AGM is held. Audited statements follow Hong Kong Financial Reporting Standards, with eligible SMEs able to apply the SME Financial Reporting Framework.

3. Diarise the first AGM and first tax return

If an AGM is required, a private company that is not a public-company subsidiary generally holds it within 9 months after the first accounting reference period ends. If that period exceeds 12 months, a different deadline applies. It is the later of 9 months after incorporation's first anniversary or 3 months after the period ends.

The first Profits Tax return is generally issued around month 18 after incorporation, and the company then has three months to file it with the supporting documents required in its circumstances. A corporation with gross income generally submits audited financial statements and a tax computation with its return, even if its gross income does not exceed HK$2 million. If it has no gross income, supporting documents generally need not accompany the return, although they must still be prepared. Dormant companies are exempt from audit and may file without those supporting documents.

How Do You Build the Calendar Step by Step?

Work backwards: fix the year end, plan from each applicable deadline, assign owners, then re-baseline the plan each year.

A calendar fails when dates float without owners. The five steps below turn the statutory list into a working plan. The December year-end example assumes an active private company with an applicable Block Extension Scheme extension.

Step 1: Fix the financial year end

Set the year end before the first accounting period closes. The choice fixes the tax code, the AGM window and the filing dates, so changing it later resets the whole calendar.

Step 2: Reverse-engineer each deadline

Start from the statutory date and plan backwards. For a company required to hold an AGM, complete any required audit before that meeting and allow time to submit audited accounts with the Profits Tax return when required. A December year-end company can plan fieldwork for the first quarter and, if eligible for the 2025/26 block extension, file by 17 August 2026 on paper or 17 September 2026 if e-filed with the further extension.

Step 3: Assign owners and layered reminders

Give every date a named owner, whether the company secretary or outsourced Corporate Professional Advisors. Set reminders at 90, 30 and 7 days so audit, board papers and filings never collide.

Step 4: Log change events immediately

Registered-office and officer changes carry their own notification windows, and a company registry search in Hong Kong shows the particulars currently on file. Add each event to the calendar the day it happens.

Step 5: Re-baseline every year

Fees and schemes move: the one-year Business Registration Certificate costs HK$2,350 from 1 April 2026, and e-filing rules keep expanding. Review our corporate compliance requirement timeline each year of assessment and refresh the plan. Your Hong Kong compliance calendar should be a living document, not a filing-season afterthought.

What Happens If a Deadline Is Missed?

Expect higher fees first, then penalties, estimated assessments and, for persistent default, court action.

According to the Companies Registry, a local private company's annual return generally must arrive within 42 days of its incorporation anniversary. Late delivery means a higher fee. Persistent default is an offence that can end in prosecution. On the tax side, the IRD may issue estimated assessments when returns are late, add penalties and charge surcharges on tax in arrears.

Beyond the fines, stale filings slow bank account reviews, loan applications and due diligence during a sale. A missed audit has its own knock-on effect: an AGM, if required, may be unable to table compliant accounts, and the Profits Tax return may be delayed where audited accounts must accompany it. One slip therefore moves three obligations at once, which is why every calendar deserves a named owner.

Conclusion

For a local private company, file Form NAR1 within 42 days of each incorporation anniversary unless exempt. Hold the AGM when required, and renew the Business Registration Certificate on time. Match the Profits Tax return to its applicable due date or extension. Do those four things and the calendar largely runs itself.
