Form BIRSP5 Tax Concessions for Intellectual Property Income

Form BIRSP5 claims a reduced profits tax rate on qualifying intellectual property income. It enacts Hong Kong’s patent box regime, introduced in the Inland Revenue Ordinance (Cap. 112), and accompanies the profits tax return (BIR51 or BIR52). The form requires a detailed breakdown of the qualifying IP assets, the income derived from them, and the tax computation at the concessionary rate. The Inland Revenue Department (IRD) uses this information to assess eligibility and verify the calculation.

IP Income Tax Concession Hong Kong

Hong Kong’s patent box regime offers a concessionary tax rate of 5% on qualifying intellectual property income, a rate set by section 14E of the Inland Revenue Ordinance (Cap. 112). This is a significant reduction from the standard corporate profits tax rate of 16.5% (or 8.25% under the two-tiered regime). The concession targets income from the use of, or the right to use, qualifying intellectual property such as patents, copyrighted software, or other protected IP rights. The policy encourages research and development (R&D) and the commercialisation of IP in Hong Kong.

Form BIRSP5 Eligibility

Eligibility requires income from qualifying intellectual property assets. The IRD defines qualifying IP as patents, utility models, copyrighted software, and other legally protected rights registered in Hong Kong or a WTO member jurisdiction. The taxpayer must have undertaken qualifying R&D activities in Hong Kong that created or developed the IP. Only income directly attributable to this IP qualifies, including royalty income, licensing income, and proceeds from the sale of the IP itself. Income from marketing-related IP like trademarks or brand names is excluded.

Intellectual Property Tax Deduction HK

A tax deduction for IP expenditure operates alongside the patent box concession. Taxpayers can deduct expenditure incurred in creating or acquiring qualifying IP, subject to the normal capital allowance rules in the Inland Revenue Ordinance. This deduction reduces chargeable income before the concessionary rate is applied. For R&D expenditure, a separate deduction is available under section 16E of the Inland Revenue Ordinance (Cap. 112). This provides a 100% deduction for qualifying R&D expenditure and an additional 200% deduction for specified activities. Taxpayers can therefore reduce their taxable income through deductions and then apply the 5% rate to the remaining amount.

Hong Kong IP Tax Regime

Hong Kong’s IP tax regime uses a modified nexus approach. The concessionary rate applies only to the portion of IP income that reflects R&D activities conducted in Hong Kong. The calculation is a fraction: qualifying expenditure (R&D incurred in Hong Kong) divided by overall expenditure (total global R&D). This fraction is applied to gross IP income to determine the amount eligible for the 5% rate. The remaining income is taxed at the standard rate. Taxpayers must maintain detailed records of R&D activities and expenditure to support this calculation. The IRD may request this information during an audit.

Form BIRSP5 Filing Instructions

File Form BIRSP5 with the profits tax return for the relevant assessment year. The form is structured into several parts.

  • Part A: Taxpayer identification details, including the business registration number and assessment year.
  • Part B: Description of the qualifying IP assets, including type, registration number, and jurisdiction.
  • Part C: Calculation of gross IP income, broken down by source such as royalties, licensing fees, or IP sales.
  • Part D: Calculation of the qualifying fraction, showing Hong Kong R&D expenditure and total global R&D expenditure.
  • Part E: Application of the qualifying fraction to gross IP income to find the amount subject to the concessionary rate.
  • Part F: Tax computation showing tax payable at the concessionary rate and the standard rate on the remaining income.

Attach supporting documents. These include a schedule of R&D expenditure, copies of IP registration certificates, and the full tax computation. The IRD recommends electronic filing via the Tax Representative Portal or the Business Tax Portal. Paper filing is accepted but processing takes longer.

Key Deadlines and Penalties

Form BIRSP5 shares the same deadline as the profits tax return. For corporations, this is generally within one month of the return’s issue date, unless an extension is granted. Penalties for late filing may be imposed under section 82A of the Inland Revenue Ordinance (Cap. 112). The IRD can also levy additional tax if the concession is claimed incorrectly or without proper documentation.

Provisional Tax Considerations

The patent box concession affects provisional tax calculations. When a claim is made on Form BIRSP5, the IRD applies the reduced rate to qualifying IP income for the following year’s provisional tax estimate. Ensure the provisional tax computation reflects this to avoid overpayment. If you expect the concession to apply in future years, you may apply for a holdover of provisional tax using Form IR1121. The IRD will consider the application on its merits.

Role of the Tax Representative

A tax representative can file Form BIRSP5 on a taxpayer’s behalf. The representative must have authority to act under section 5 of the Inland Revenue Ordinance (Cap. 112). They are responsible for completing the form accurately and providing all required documentation. The IRD will correspond directly with the tax representative about the form and any related queries.

Interaction with Other Forms

Form BIRSP5 is one of several supplementary forms filed with the profits tax return. It is distinct from Form BIRS22, which is used for a different IP income tax concession. Use the correct form for the specific concession claimed. If you are also claiming R&D expenditure deductions, file Form BIRSP2 separately. The IRD cross-references information across these forms to ensure consistency.

Record Keeping Requirements

Retain all records related to the IP assets and R&D expenditure for at least seven years after the end of the relevant assessment year. These records must include contracts, invoices, timesheets, and other documents proving the nature and extent of the R&D activities. The IRD may request these records during an audit. Inadequate record-keeping can lead to the concession being disallowed and penalties being imposed.

How to fill out Form BIRSP5: page one of the Tax concessions for intellectual property income form from the Companies Registry

Part 1: Taxpayer identification

Box 1 - Name of taxpayer: Enter the full legal name of the company or individual claiming the concession. This must match the name registered with the Inland Revenue Department (IRD).

Box 2 - Business Registration Number: Enter the 8-digit number shown on the Business Registration certificate. This is the number used on your Profits Tax Return.

Box 3 - File number (if known): If the IRD has already assigned a tax file number for the relevant year of assessment, enter it here. Otherwise leave blank.

Box 4 - Year of assessment: Write the year of assessment in the format “YYYY/YY”, for example “2024/25”. This must be the year to which the IP income relates.

Part 2: Election for tax concessions

Box 5 - Type of IP income: Tick only one box. You may tick either “Royalty income” or “Capital gains from disposal of intellectual property”. These are mutually exclusive - you cannot claim both concessions for the same IP in the same year.

Box 6 - Description of the intellectual property: Provide a clear description of the IP (e.g., patent number, trademark registration, copyright work, registered design). Include any official registration number if applicable. For unregistered IP, state the nature of the right and how it is owned.

Box 7 - Date of acquisition of the IP: Enter the date the taxpayer acquired the IP. This must be a specific day (DD/MM/YYYY). The date should match supporting documents such as the assignment deed, licence agreement, or certificate of registration.

Part 3: Calculation of concession amount

Box 8 - Gross IP income for the year: Enter the total gross income derived from the IP during the year of assessment - before any deductions. For royalty income, this is the gross royalties received. For capital gains, this is the gross disposal proceeds.

Box 9 - Direct expenses attributable to the IP: Enter the total direct expenses incurred in generating the IP income, such as legal fees for patent protection, agency commissions, or reproduction costs. Do not include general overheads.

Box 10 - Net IP income (Box 8 minus Box 9): This is automatically calculated. Double-check the arithmetic, as a wrong figure here will affect the concession claim.

Box 11 - Qualifying IP income - amount claimed as concession: Enter the amount of net IP income that qualifies for the concession. This cannot exceed the net IP income in Box 10. The IRD may request a breakdown of how this amount is determined.

Part 4: Declaration

Box 12 - Signature of taxpayer / authorised person: The form must be signed by the taxpayer (if an individual) or by a director, secretary, or other authorised person (if a company). The signatory must have authority under the company’s articles or the IRD’s guidelines.

Box 13 - Name in full: Print the full name of the signatory.

Box 14 - Date: Enter the date of signature in DD/MM/YYYY format. The date must be on or before the filing deadline for the relevant Profits Tax Return.

Box 15 - Capacity of signatory (if signing on behalf of a company): State the position held, e.g., “Director”, “Secretary”. Do not use generic terms like “Authorised person” without specifying the role.

Common mistake: Box 5 is often ticked incorrectly - remember that you cannot claim both royalty and capital gains concessions for the same IP in the same year. If you have both types of income, you must file separate forms or contact the IRD for guidance. Also, Box 7 (date of acquisition) is frequently left blank - the IRD will reject the form if it is missing.
