Tax Representative Appointment (Hong Kong)

Under the Inland Revenue Ordinance (Cap. 112), any person authorised in writing by a taxpayer can act as their tax representative before the Inland Revenue Department. In practice, tax representatives are almost always certified public accountants (CPAs) registered with the Hong Kong Institute of Certified Public Accountants (HKICPA), tax advisers at major accounting firms such as the Big Four, or specialist tax consultancies. Solicitors who advise on tax matters may also represent taxpayers before the IRD, particularly in contentious matters involving tax objections under Section 64 of Cap. 112 or appeals to the Board of Review under Section 66. The IRD does not maintain a formal register of approved tax representatives in the same way that some other jurisdictions accredit tax agents, but it does operate a Block Extension Scheme — a tax return filing extension programme — that is available only to taxpayers represented by a CPA firm or tax adviser who has enrolled in the scheme. Enrolled representatives receive extended filing deadlines, allowing companies with accounting year-ends between April and December to file profits tax returns as late as the following April or August rather than within one month of the return being issued. A properly executed Tax Representative Appointment letter is required to initiate this arrangement and to authorise the representative to correspond with, receive documents from, and negotiate with the IRD on the taxpayer's behalf.

A tax representative appointed under the Inland Revenue Ordinance (Cap. 112) has the authority defined in the appointment letter — the Tax Representative Appointment. The authority can be general, covering all dealings with the Inland Revenue Department across all taxes and all years, or specific, limited to a particular year of assessment, a particular tax type, or a particular matter such as an objection or audit. A general tax representative appointment authorises the representative to receive all IRD correspondence and notices on the taxpayer's behalf, to file tax returns and accompanying documents, to submit computations, to correspond and negotiate with IRD assessors regarding assessments and deductions, to lodge objections under Section 64 of Cap. 112 on the taxpayer's behalf, to attend meetings and interviews with IRD investigators, and to apply for holdovers of provisional tax under Section 71(2) of Cap. 112. The appointment does not automatically authorise the representative to settle a tax dispute by accepting an adjusted assessment without the taxpayer's specific consent, nor does it allow the representative to authorise a search of the taxpayer's premises under Section 52 of Cap. 112. The Tax Representative Appointment letter should specify the scope clearly to avoid disputes about the extent of the representative's authority in dealings with both the IRD and third parties.

One of the most significant practical benefits of appointing a tax representative enrolled in the Inland Revenue Department's Block Extension Scheme is the extended filing deadline for profits tax returns under the Inland Revenue Ordinance (Cap. 112). Without a tax representative, a profits tax return (BIR51 for corporations) must be filed within one month of the date of issue — typically by the end of May for returns issued in April. With an enrolled tax representative, the filing deadline is extended based on the company's accounting year-end date: companies with year-ends between 1 April and 30 November receive an extended deadline typically in the following January; companies with December year-ends receive an extended deadline in August. These extensions apply automatically to all clients of the enrolled representative and do not require individual application. Salaries tax returns (BIR60) also benefit from extensions for taxpayers with represented filing arrangements. The Tax Representative Appointment letter must be in place before the representative can enrol the taxpayer in the Block Extension Scheme. Where a company changes its tax representative mid-year, the new representative should notify the IRD of the change by submitting a new Tax Representative Appointment letter and the old representative should confirm their withdrawal. The IRD sends all future correspondence to the representative's address once the appointment is registered on the IRD's file.

A tax representative appointed under a Tax Representative Appointment letter can lodge a formal objection to a tax assessment under Section 64 of the Inland Revenue Ordinance (Cap. 112) on the taxpayer's behalf, provided the appointment grants authority to do so. The representative signs the objection letter in their own name as agent for the taxpayer, and the IRD treats the objection as having been made by the taxpayer. Where the objection is unsuccessful and the taxpayer wishes to appeal to the Board of Review under Section 66 of Cap. 112, the representative can file the notice of appeal on behalf of the taxpayer and represent the taxpayer at the Board of Review hearing. The Board of Review is an independent statutory tribunal presided over by legally qualified chairpersons and its hearings are conducted in a judicial manner with examination of witnesses, submission of evidence, and legal argument. CPAs and tax advisers — even if not qualified barristers or solicitors — may appear before the Board of Review as representatives. For appeals to the Court of First Instance on points of law under Section 69 of Cap. 112, or to the Court of Appeal or Court of Final Appeal, the taxpayer would typically need to instruct a barrister through a solicitor. The Tax Representative Appointment letter should expressly authorise the representative to conduct litigation and appear before tribunals if those powers are required.

A Tax Representative Appointment can be revoked by the taxpayer at any time by submitting a written revocation notice to the Inland Revenue Department, identifying the taxpayer's IRD file number, the name of the current representative being removed, and the effective date of revocation. The revocation should be sent directly to the IRD rather than through the outgoing representative, to avoid any conflict of interest. Where a new representative is being appointed simultaneously, the new Tax Representative Appointment letter can be submitted at the same time, and the IRD will transfer the file to the new representative. The outgoing representative should also be notified in writing of the revocation and asked to return all the taxpayer's documents and records. From the effective date of revocation, the IRD will cease sending correspondence to the old representative and will revert to sending all notices to the taxpayer's own address unless a new representative is on file. Where the outgoing representative held the taxpayer in the Block Extension Scheme, the new representative must enrol the taxpayer under their own block extension arrangement to preserve the extended filing deadlines — otherwise the taxpayer may revert to the standard one-month deadline for the next tax return.

When appointing a new tax representative in Hong Kong, the taxpayer should provide a signed Tax Representative Appointment letter addressed to the Commissioner of Inland Revenue under the Inland Revenue Ordinance (Cap. 112), identifying the taxpayer's full name, IRD file number, the name and address of the appointed representative, the scope of authority, and the years of assessment and tax types covered. In addition, the taxpayer should supply a copy of their HKID card (for individuals) or a copy of the company's Business Registration Certificate and Certificate of Incorporation issued by the Companies Registry (for companies), to allow the representative to verify identity with the IRD. The taxpayer should also provide all previous IRD correspondence including tax return forms, notices of assessment, demand notes, and any existing objection or holdover application correspondence, so the representative can review the historical tax position. For companies, the previous three years of audited financial statements and filed profits tax returns and computations should be provided so the representative can understand the accounting policies, prior-year adjustments, and any carried-forward losses. Where the appointment covers a specific matter such as a pending objection or audit, all correspondence relating to that matter should be shared. The representative will then submit the signed Tax Representative Appointment letter to the IRD and register the appointment on the taxpayer's file.
