Hong Kong’s corporate compliance calendar remains one of Asia’s most document-intensive, with several regulatory changes taking effect in 2026. On 1 April 2026, the Inland Revenue Department (IRD) issued approximately 270,000 Profits Tax Returns, 120,000 Property Tax Returns and 340,000 Employer’s Returns, followed by another 2.77 million Individual Tax Returns on 4 May. This volume highlights the scale of Hong Kong’s annual tax and regulatory filing obligations, with many statutory filings due within one month of issuance.
Corporate compliance in Hong Kong is administered by multiple authorities, including the Companies Registry, the Inland Revenue Department (IRD) and, for designated operators, the Commissioner of Critical Infrastructure (Computer-system Security). Each operates under separate statutory deadlines and reporting requirements.
Even dormant companies remain subject to certain ongoing obligations, including filing the Annual Return (NAR1) and renewing the Business Registration Certificate. Designated critical infrastructure operators must also report qualifying cybersecurity incidents within 12 hours of becoming aware of a substantial incident, with a separate 48-hour reporting requirement applying in other prescribed circumstances under the Ordinance.
This guide outlines the Hong Kong compliance deadlines and penalties in force for 2026.
Annual Return (NAR1) in Hong Kong
A statutory document filed each year with the Hong Kong Registry, submitted using Form NAR1, provides the Registry with a confirmed view of the company’s details. Every private limited company must file an annual return each year, even if the company had no transactions during the year, made no changes to its directors, and is currently dormant. The deadline is 42 days after your incorporation anniversary.
1. Who Must File
Private companies limited by shares incorporated in Hong Kong.
Companies limited by guarantee incorporated in Hong Kong.
Non-Hong Kong companies registered under Part 16 of the Companies Ordinance are not required to file Form NAR1. Instead, they must file Form NN3.
2. Penalties for late filing
| Delay Period | Late Filing Fee |
|---|---|
| Within 42 days of the company’s return date | HK$105 |
| More than 42 days, but within 3 months | HK$870 |
| More than 3 months, but within 6 months | HK$1,740 |
| More than 6 months, but within 9 months | HK$2,610 |
| More than 9 months | HK$3,480 |
In addition to the late filing fee, the Companies Registry can also prosecute the company and any responsible officer (director or company secretary) in default. Each summary conviction can carry a further fine of up to HK$50,000 per officer, and the court can impose a daily default fine for continued non-filing.
Business Registration Certificate Renewal
A business registration certificate is a legal document issued by the Business Registration Office which registers the business for tax purposes and assigns the Unique Business Identifier. It serves as the official record confirming a business identity with the government. Every BRC shows the business name, address, business type, date of commencement, and expiry date.
Hong Kong business registration renewal takes three years, depending on the duration chosen by the business at the time of registration. When the BRC is renewed, the company must receive the business registration renewal demand notice. Businesses are required to act promptly to renew their BRC before its expiry date. Submit a payment for the mandatory renewal fee; for a one-year certificate, it is HK $2,200, and for a three-year certificate it is HK $ 5,870.
Penalty for Non-Compliance
| Non-Compliance | Penalty (Hong Kong – 2026) |
|---|---|
| Failure to renew the Business Registration Certificate and continuing to carry on business without a valid certificate | Fine of up to HK$5,000 and imprisonment for up to 1 year. |
| Business registration application made more than 12 months after the business commenced (or remained unregistered) | Payment of the current year’s Business Registration fee and levy plus any back years’ Business Registration fees and levies that are payable. |
| Failure to display the valid Business Registration Certificate at the business premises | Fine of up to HK$5,000. |
Even a company that has formally declared dormancy with the Companies Registry (Form D2A) must still renew its Business Registration Certificate every year, as dormancy exempts a company from filing NAR1 and Profits Tax Returns in some cases, but not from BR renewal.
Profits Tax Return (PTR)
On 1 April 2026, the IRD issued around 270,000 Profit Tax Returns for the year of Assessment. Large MNE groups must demonstrate that their effective tax rate in each jurisdiction meets the 15 per cent global minimum. A profit tax return is the form BIR 51 used to report assessable profit for a year of assessment. It serves as the basis for determining how much profit tax the business must pay.
All entities carrying or starting a business in Hong Kong are required to pay tax, even if the company made no profit or remained inactive. For newly incorporated companies, the IRD issues the first Profit Tax Return about 18 months after the date of incorporation. After this, you can file the PTR form along with any required supplementary forms within 1 month of the issue date. For businesses that have commenced operations, IRD issues a Profit Tax Return on the first day of April. If the company has a registered tax representative, it may qualify for extended deadlines under the IRD’s Block Extension Scheme. The IRD encourages taxpayers to file their tax returns through eTax. Individual users can use “iAM Smart” to log in and sign their tax returns.
1. Block Extension Scheme deadlines
- N Code (Accounting date: 1 April – 30 November): Extended filing deadline is 15 November.
- D Code (Accounting date: 1 December – 31 December): Extended filing deadline is 15 August of the following year.
- M Code (Accounting date: 1 January – 31 March): Extended filing deadline is 15 November of the same year. Companies reporting losses are generally granted a further extension until 31 January of the following year.
2. Penalty for Non-Compliance
| Non-Compliance | Penalty |
|---|---|
| Late filing of a Profits Tax Return | Fine of up to HK$10,000 |
| Failure to file a Profits Tax Return | Fine of up to HK$10,000 plus possible prosecution |
| Filing an incorrect Profits Tax Return without reasonable excuse | Fine of up to HK$10,000 plus three times the amount of tax undercharged |
| Wilfully submitting false information or making fraudulent tax returns | Fine of up to HK$50,000, three times the amount of tax undercharged, and possible imprisonment |
| Failure to keep proper business records | Fine of up to HK$100,000 |
Note: Section 51C of the Inland Revenue Ordinance requires businesses to keep sufficient records in English or Chinese for at least 7 years from the transaction date. This applies even to dormant or loss-making companies and is one of the most commonly overlooked penalties on this list.
Employer’s Return Compliance
Employer’s return is an annual declaration that every employer in Hong Kong must submit to the IRD. An Employer’s Return is also known as BIR56A and FormIR56B issued to employers each year. The purpose of the Employer’s Return is to facilitate the IRD’s assessment of the employee’s tax liabilities for 1 April to 31 March of each year.
If an individual owns a company in Hong Kong that already employs staff, the company is required to keep payroll records and report employees’ earnings. The IRD issues BIR56A each year on the first working day of April. Employers must complete and return it, together with an IR56B for each employee, within one month of the issue date, even if the company has no employees for that year (a “Nil” return is still required).
- Form IR56E: Submit within 3 months of a new employee commencing employment.
- Form IR56F: Submit at least one month before an employee ceases employment.
- Form IR56G: Submit at least one month before an employee leaves Hong Kong permanently or for a substantial period. Employers are also required to withhold final payments until the Inland Revenue Department completes the tax clearance process.
Failure to submit these event-based forms may attract the same penalties as failing to file the annual BIR56A/IR56B Employer’s Return.
Penalty for Non-Compliance
| Non-Compliance | Penalty |
|---|---|
| Failure to file an Employer’s Return (Form BIR56A/IR56B) without a reasonable excuse | Fine of up to HK$10,000 |
| Late submission of an Employer’s Return | Up to HK$10,000 |
| Filing an incorrect Employer’s Return without a reasonable excuse | Fine of up to HK$10,000, plus up to 3× the amount of tax undercharged |
| Deliberately filing a false Employer’s Return or committing tax fraud | Fine of up to HK$50,000, plus up to 3× the tax undercharged, and imprisonment for up to 3 years |
| Continued failure to comply after a court order | Court may order the employer to file the required return within a specified time |
Cybersecurity Ordinance Compliance Penalties (Effective 2026)
The Protection of Critical Infrastructures (Computer Systems) Ordinance is Hong Kong’s cybersecurity law that came into effect in 2026. It requires designated operators of critical infrastructure to protect their computer systems against cybersecurity risks.
The Ordinance requires designated operators to maintain a cybersecurity management framework, conduct regular cybersecurity risk assessments and audits, establish incident response and contingency plans, report specified cybersecurity incidents within the prescribed timeframes, and comply with directions issued by the Commissioner. It applies to organisations operating critical infrastructure in sectors such as banking and financial services, healthcare, information technology, telecommunications, transport, energy, and other essential services.
| Non-Compliance | Penalty (Hong Kong – 2026) |
|---|---|
| Failure to comply with a statutory direction issued by the Commissioner | Fine of up to HK$500,000, plus a daily fine of HK$50,000 for continuing non-compliance. |
| Failure to report a specified cybersecurity incident within the required timeframe | Fine of up to HK$500,000, plus a continuing daily fine where applicable. |
| Failure to implement or maintain the required cybersecurity measures | Fine of up to HK$500,000, plus additional daily penalties for continuing offences. |
| Providing false, misleading, or inaccurate information to the Commissioner | Fine of up to HK$500,000 and possible prosecution under the Ordinance. |
Penalties under the Ordinance apply at the organisational level only, and individual staff of a designated operator are not personally liable under the Ordinance itself, though company officers can still face liability under general corporate and criminal law principles for related misconduct.

Repeated non-compliance may result in higher financial penalties, prosecution, court orders, or other regulatory enforcement actions, depending on the nature and seriousness of the breach. A poor compliance history may also increase regulatory scrutiny in the future.
