BEPS Pillar Two – Key Compliance Timeline and How Boardroom Can Assist

BEPS Pillar Two – Key Compliance Timeline and How Boardroom Can Assist

Illustrative Timeline for Hong Kong Constituent Entities

Hong Kong has enacted legislation to implement BEPS Pillar Two (Global Minimum Tax) with effect from financial years beginning on or after 1 January 2025. Multinational enterprise (“MNE”) groups that meet the relevant revenue thresholds are subject to new notification, filing and administrative obligations in Hong Kong.

This article:

  • provides an overview of key Pillar Two compliance milestones, including both the Top-up Tax Notification and the Top-up Tax Return;
  • highlights common first-year compliance challenges; and
  • explains how Boardroom can assist affected groups.

An illustrative timeline for a group with a 31 December 2025 financial year‑end is included for reference only. Groups with different financial year‑end dates should adjust the timeline accordingly by reference to their own year‑end.

This note is intended for general guidance only and should not be regarded as exhaustive or as a substitute for professional advice.

Overview – Why Pillar Two Matters

Pillar Two introduces a 15% global minimum effective tax rate for large MNE groups and establishes a new compliance framework, including annual notifications, returns and mandatory electronic filing requirements.

Key points to note:

  • Pillar Two compliance is determined at the group level, not by reference to the size or profitability of individual Hong Kong entities.
  • Compliance obligations (including both the Top-up Tax Notification and Top-up Tax Return) apply even where no Pillar Two top-up tax is ultimately payable.
  • Registration and administrative readiness (e.g., Business Tax Portal (“BTP”) access, Pillar Two Group Code, and service provider appointments) are critical to meeting statutory deadlines.

Early preparation is therefore strongly recommended.

General Pillar Two compliance framework

For a Hong Kong constituent entity of an in‑scope MNE group, Pillar Two compliance will typically involve:

  • Assessing Pillar Two in‑scope status at group level;
  • Registering for the BTP and applying for Pillar Two MNE Group Code / JV Code(s);
  • Filing an annual Top‑up Tax Notification within six months after the end of the relevant financial year;
  • Preparing and filing an annual Top-up Tax Return within the applicable filing deadline (15 months after year-end, or 18 months for the first transition year); and
  • Ongoing alignment with existing Hong Kong tax compliance obligations, including Profits Tax Returns (mandatory electronic filing from YA 2025/26), transfer pricing documentation, and Country-by-Country reporting.

Note: Each Hong Kong constituent entity that is designated to submit Pillar Two filings is required to register its own dedicated BTP Business Account. For designated filing entities, BTP registration is a mandatory prerequisite for submitting the Pillar Two Top‑up Tax Notification and Top‑up Tax Return, and for appointing a service provider to handle such filings. Unlike ordinary Profits Tax Returns, Pillar Two requires entity‑level BTP registration before a service provider can be properly authorised through the IRD’s Pillar Two Portal. Based on prevailing IRD administrative practice, a Hong Kong constituent entity that is relieved from filing its own Top‑up Tax Notification and Return may not be required to maintain an active BTP Business Account, unless it is subsequently designated as a filing entity or elects to register one for administrative convenience.

Illustrative timeline – group with a 31 December 2025 financial year‑end

The timeline below illustrates how Pillar Two compliance may unfold for a group with a 31 December 2025 year‑end, which represents the first cohort of groups required to file a Top‑up Tax Notification in Hong Kong. Groups with other year‑ends should use this as a reference and apply the same principles based on their own financial year‑end.

Key considerations for groups with non‑December year‑ends

Groups with financial year‑ends other than 31 December should note that:

  • The Top‑up Tax Notification must be filed within six months after the end of the relevant financial year.
  • The Top-up Tax Return must be filed within 15 months after the end of the relevant financial year (extended to 18 months for the first transition year of the group).
  • Early planning is particularly important for the first year of application, irrespective of the accounting date. BTP registration and Group Code application should commence well ahead of the notification deadline.

Common first‑year compliance challenges

As with other new tax compliance regimes, first‑year implementation of Pillar Two often presents the following challenges:

  • Late identification of in‑scope status, particularly for groups with overseas headquarters;
  • Delays in BTP registration, service provider appointment, and Pillar Two Group Code application;
  • Unclear internal ownership between group tax teams and Hong Kong finance teams;
  • Data consistency issues across Pillar Two, transfer pricing and Country‑by‑Country reporting; and
  • Underestimating the time required for first‑year registrations and internal approvals, even where no top‑up tax is expected.

Addressing these issues early can significantly reduce compliance risk and administrative burden.

How Boardroom can assist

Boardroom provides end‑to‑end Pillar Two compliance support tailored to Hong Kong entities and multinational groups, including:

Pillar Two scope assessment

  • Assessing whether your group falls within Pillar Two scope based on consolidated revenue and group structure;
  • Identifying which Hong Kong entities are affected and their respective compliance obligations.

Registration and portal readiness

  • Assisting with BTP registration and setup for each Hong Kong constituent entity;
  • Supporting applications for Pillar Two MNE Group Codes / JV Codes;
  • Establishing appropriate filing roles, authorisations, and internal controls, including service provider appointments via BTP.

Top‑up Tax Notification and Return

  • Preparing and filing the Top‑up Tax Notification;
  • Preparing and filing of the Top‑up Tax Return;
  • Liaising with overseas group tax teams to ensure consistent global filing positions.

Ongoing compliance and alignment

  • Integrating Pillar Two requirements into your existing Hong Kong tax compliance framework;
  • Aligning Pillar Two data with Profits Tax Returns, transfer pricing documentation and Country-by-Country reporting;
  • Providing ongoing compliance support in subsequent years.

Recommended next steps

Given the tight first‑year timelines, groups that may be affected by Pillar Two should consider:

  • Confirming Pillar Two in‑scope status as early as possible;
  • Identifying a Hong Kong point‑of‑contact and potential designated filing entity; and
  • Initiating BTP registration and Pillar Two Group Code application well ahead of the notification deadline; and
  • Engaging professional support for coordinated global and local compliance.

We encourage potentially affected groups to engage early, particularly in relation to first-year registration, portal readiness, notification, and return requirements.

Profits Tax Filing – 2025/26 Key Deadlines and Compliance Points

Profits Tax Filing – 2025/26 Key Deadlines and Compliance Points

Profits Tax Filing – 2025/26 Key Deadlines and Compliance Points

The Inland Revenue Department (“IRD”) conducted the bulk issuance of 2025/26 Profits Tax Returns in early April. Businesses should now review the applicable filing deadlines and any new compliance obligations for the current year.

Profits Tax Return Obligations – Overview

Hong Kong companies (and non-Hong Kong companies carrying on business in Hong Kong) are required to comply with ongoing profits tax reporting obligations. These obligations apply to both first-time Profits Tax Returns and subsequent annual returns.

Where a tax representative has been properly appointed, Profits Tax Returns may be filed under the Block Extension Scheme, subject to the entity’s accounting date.

First Profits Tax Return

For newly incorporated Hong Kong companies, the IRD typically issues the first Profits Tax Return (“PTR”) around 18 months after incorporation. Upon receipt, the first PTR is generally required to be filed within three months.

Annual Profits Tax Returns (Including Years Where No PTR Is Issued)

After the first PTR has been filed, the IRD normally issues Profits Tax Returns annually. In practice, the IRD may temporarily suspend issuing returns for companies that have previously reported nil assessable profits or substantial tax losses. Such arrangements are administrative, non-statutory, and may be withdrawn at any time.

Even where a Profits Tax Return is not issued, businesses remain subject to Hong Kong tax compliance obligations. Preparing annual profits tax computations and maintaining supporting documentation can help mitigate future compliance risks, support tax positions, reduce administrative pressure when filings resume, and demonstrate a consistent compliance record with the IRD.

Filing Deadlines for 2025/26

For the current year of assessment, the following statutory and extended filing deadlines apply to both first-time and subsequent Profits Tax Returns where a tax representative has been appointed:

  • Accounting date between 1 April 2025 and 30 November 2025
    → No block extension applies
    → Returns are generally due one month from the issue date (or three months for the first PTR)
  • Accounting date between 1 December 2025 and 31 December 2025
    → Extended filing deadline: 17 August 2026
  • Accounting date between 1 January 2026 and 31 March 2026
    → Extended filing deadline: 16 November 2026

Businesses should identify their applicable deadlines early to allow sufficient time for audit completion and internal review.

Mandatory Electronic Filing for Pillar Two In-Scope Groups

With effect from the Year of Assessment 2025/26, Hong Kong constituent entities of multinational enterprise (“MNE”) groups within the scope of BEPS Pillar Two are required to electronically file their Profits Tax Returns via the IRD’s Business Tax Portal (“BTP”).

This requirement applies regardless of whether:

  • Hong Kong profits tax is payable; or
  • Pillar Two top-up tax arises

Affected entities should ensure that appropriate BTP registration, user access, and digital authorisation arrangements are in place. Entities subject to mandatory electronic filing may also be eligible for an additional one-month filing extension, subject to proper notification to the IRD.

Penalties and Enforcement

Failure to comply with Profits Tax Return obligations — including late filing, incorrect filings, or failure to notify chargeability — may result in penalties of up to HK$10,000 plus up to three times the amount of tax underpaid.

Companies are also required to maintain proper accounting records for at least seven years. Failure to do so may attract significant penalties.

How We Can Help

Profits tax compliance involves more than meeting filing deadlines. It requires coordination across finance, audit, and tax functions, as well as awareness of evolving administrative requirements such as mandatory electronic filing.

Our team supports clients with profits tax compliance, audit coordination, and Pillar Two obligations, helping businesses manage risk and meet their Hong Kong filing requirements efficiently. Get in touch with us to stay ahead of your 2025/26 obligations.

Understanding Offshore Tax Claims in Hong Kong

Understanding Offshore Tax Claims in Hong Kong

Understanding Offshore Tax Claims in Hong Kong

Hong Kong adopts a territorial basis of taxation, whereby Profits Tax is generally chargeable only where a person carries on a trade, profession, or business in Hong Kong and derives profits from that business.

Where this threshold is met, the next consideration is whether the relevant profits are sourced in or outside Hong Kong. Profits derived from activities carried out outside Hong Kong may be eligible for an offshore claim, depending on the specific facts and circumstances.

In practice, offshore claims can arise in a wide range of cross-border business arrangements. Understanding how such claims are reviewed by the Inland Revenue Department (“IRD”), as well as the associated documentation and administrative requirements, is an important aspect of effective tax management in Hong Kong.

What Is an Offshore Tax Claim?

An offshore claim is made through the Profits Tax Return, where a business that is considered to be operating in Hong Kong takes the position that some or all of its profits are sourced outside Hong Kong and therefore fall outside the scope of Hong Kong Profits Tax.

In assessing such claims, the IRD focuses on where the actual profit-generating activities are carried out, taking into account the taxpayer’s business model, operational structure, and the manner in which profits are derived.

As a result, offshore claims are highly fact-specific and depend on how a business operates in practice.

When Offshore Tax Considerations Commonly Arise

Offshore claims may be relevant where a business:

  • Deals primarily with overseas customers
  • Negotiates or concludes contracts outside Hong Kong
  • Conducts manufacturing, logistics, or service activities offshore
  • Relies on overseas personnel or group entities to perform key business functions

Even where a business is carried on in Hong Kong, these factors may raise questions as to whether the resulting profits are sourced outside Hong Kong.

How Offshore Claims Are Assessed

Once an offshore claim is made, it is common for the IRD to issue enquiry letters requesting information and documentation to substantiate the claim.

The IRD typically expects:

  • Clear explanations of the business model and operational arrangements
  • Evidence of where key profit-generating activities are performed
  • Contemporaneous documentation supporting the offshore position

Each claim is assessed on its own merits, based on the relevant facts and supporting evidence. Insufficient or inconsistent documentation may significantly reduce the likelihood of a successful claim.

Why Early Awareness and Preparation Matter

Offshore claims are not fixed and may be reviewed by the IRD at a later stage, even in years where a Profits Tax Return is not issued. Reviews may arise through reissued returns, routine enquiries, or broader tax reviews.

As IRD assessments focus on actual business operations, responding to enquiries can become time-consuming and disruptive if claims have not been properly considered in advance.

Early preparation allows businesses to:

  • Assess the relevance of offshore claims to their operations
  • Understand the IRD’s review focus
  • Prepare appropriate supporting documentation
  • Reduce uncertainty and potential disruption during enquiries

A proactive approach enables offshore claims to be managed in a structured and supportable manner, rather than on a reactive basis.

How We Can Help

Offshore claims require close alignment between a business’s operational reality and Hong Kong’s territorial tax principles. Our tax team works with businesses to assess when offshore claims may arise, understand how such claims are evaluated by the IRD, and manage the process in a practical, well-supported manner.

Individual Tax Filing – 2025/26 Key Compliance Points and Reminders

Individual Tax Filing – 2025/26 Key Compliance Points and Reminders

Individual Tax Filing – 2025/26 Key Compliance Points and Reminders

The bulk issue of the 2025/26 Individual Tax Returns took place on 4 May 2026. Individuals should be aware of their filing obligations and take steps to prepare early to ensure timely and accurate submission now that returns are issued.

Individual Tax Return Obligations – Overview

Under Hong Kong’s salaries tax regime, individuals are required to report their income and file Individual Tax Returns once issued by the Inland Revenue Department (IRD). This includes individuals who derive:

  • Employment income
  • Rental income
  • Sole proprietorship business income

Filing obligations arise regardless of whether any tax is ultimately payable. Individuals are responsible for ensuring that the information reported in their tax returns is complete and accurate, and for retaining sufficient records to support the amounts reported.

Filing Deadlines for 2025/26

Filing deadlines depend on whether an individual is represented by a tax representative and whether the case involves sole proprietorship business income.

Based on the IRD’s announced timetable:

  • For represented cases not involving sole proprietorship business accounts, a block extension for submission of Individual Tax Returns will be granted to 4 July 2026
  • For cases involving sole proprietorship business accounts (irrespective of accounting date), the extended filing deadline will be 5 October 2026

For unrepresented cases, Individual Tax Returns are generally required to be filed within one month from the date of issue.

An automatic one-month extension is generally available for taxpayers who file their returns electronically.

Individuals should confirm early whether they are filing on a represented or unrepresented basis to ensure the correct deadline is observed.

Common Areas Requiring Attention

Individual tax filings may involve additional complexity where taxpayers have:

  • Employment income with cross-border or multi-jurisdictional elements
  • Bonuses, commissions, equity-based compensation, or termination payments
  • Rental income from Hong Kong property
  • Sole proprietorship or other business income
  • Changes in employment, role, or residency status during the year
  • Claims for deductions or personal allowances

Changes in personal or employment circumstances may affect both reporting obligations and tax exposure.

Importance of Early Preparation

Preparing early allows taxpayers to:

  • Identify potential reporting issues or changes in tax position
  • Gather and verify income details and supporting documentation in advance
  • Reduce the risk of late filing, errors, or follow-up enquiries from the IRD

Early review is particularly important where business income or overseas elements are involved.

Penalties and Compliance

Failure to file an Individual Tax Return on time, or the submission of incorrect or incomplete information, may result in penalties of up to HK$10,000, plus up to three times the amount of tax undercharged.

Maintaining proper records and ensuring accurate reporting remain key to managing individual tax compliance risk.

How We Can Help

Individual tax compliance may involve complexities beyond routine return filing, particularly where business income, cross-border employment arrangements, or variable compensation structures are involved.
