Form BIRS7 Authorized Captive Insurer Profits Tax Computation

Purpose of Form BIRS7 for Authorized Captive Insurers

Form BIRS7 computes an authorized captive insurer's profits tax liability in Hong Kong. This supplementary form accompanies the Profits Tax Return (BIR51), breaking down the assessable profits from the captive insurance business. The Inland Revenue Department requires it because captive insurers operate under a distinct tax concession regime, not the standard profits tax computation for general insurers.

A captive insurer is a wholly-owned subsidiary established by a parent company to insure the parent's own risks. Its primary function is risk retention within the corporate group, unlike commercial insurers that underwrite third-party policies. Hong Kong provides a concessionary profits tax rate for authorized captive insurers to encourage their establishment in the jurisdiction.

Form BIRS7 Authorized Captive Insurer Profits Tax Computation

Any entity authorized as a captive insurer under the Insurance Ordinance (Cap. 41) and granted a tax concession by the Inland Revenue Department must file Form BIRS7. The form applies to captive insurers authorized by the Insurance Authority to carry on captive insurance business in or from Hong Kong. It must be filed with the annual Profits Tax Return (BIR51) for each year of assessment the concessionary tax treatment is claimed.

The Inland Revenue Department issues the BIR51 with a notice to submit the return. The captive insurer then completes Form BIRS7 and attaches it. Electronic filers submit through the Business Tax Portal; others file by paper.

Form BIRS7 Authorized Insurer Guide: Completing the Computation

The form is a tax computation starting with the captive insurer's net premium income. Key line items include:

Gross Premium Income: Total premiums receivable from the parent company and related entities for policies written during the year. This covers direct insurance and reinsurance assumed.

Less: Premiums Ceded to Reinsurers: The portion of gross premiums ceded to external reinsurers. This deduction determines net premium income.

Net Premium Income: The result after deducting premiums ceded. This figure is the basis for the tax computation.

Less: Claims Paid and Outstanding: The captive insurer deducts claims expenses incurred during the year, including claims paid and the movement in outstanding claims provisions. The form requires a breakdown of claims by type, such as property damage, liability, or other covered risks.

Less: Commission and Brokerage Expenses: Any commission paid to brokers or agents for arranging the policies, along with brokerage fees.

Less: Management Expenses: Operating expenses, including staff costs, office rent, professional fees, and other administrative overheads. The Inland Revenue Department may scrutinize these expenses to confirm they are wholly and exclusively incurred in producing assessable profits.

Underwriting Profit or Loss: The net result after deducting all claims and expenses from net premium income.

Add: Investment Income: Interest, dividends, and other investment returns earned on the insurer's portfolio. This income is reported separately because it may be subject to the standard profits tax rate, not the concessionary rate.

Less: Investment Expenses: Expenses directly attributable to earning the investment income, such as investment management fees.

Assessable Profits: The total assessable profits before applying the concessionary tax rate. The captive insurer then applies the applicable tax rate to compute its tax liability.

Inland Revenue Captive Insurer Form: Tax Concession Details

The Inland Revenue Department grants a concessionary profits tax rate to authorized captive insurers under section 14B of the Inland Revenue Ordinance (Cap. 112). This rate applies to underwriting profits from the captive insurance business. The standard corporate profits tax rate applies to investment income and other non-underwriting profits.

The captive insurer must ensure its business qualifies for the concession. The Insurance Authority must have authorized the entity, and the policies must cover risks of the parent company or its affiliates. The Inland Revenue Department may request evidence of the captive's authorization and the nature of the insured risks.

Captive Insurer Profits Tax: Filing Requirements and Deadlines

File Form BIRS7 with the BIR51 within the time specified in the Inland Revenue Department's notice. The standard deadline is one month from the notice date, though the department may grant extensions upon application.

Electronic filers must submit through the Business Tax Portal. The tax computation must be tagged in iXBRL format. Ensure the iXBRL tagging covers all relevant line items in Form BIRS7, including premium income, claims expenses, and investment income.

Retain supporting documents. These include the captive insurance policies, reinsurance agreements, claims records, and investment statements. The Inland Revenue Department may request these documents during a tax audit to verify the computation's accuracy.

Specific Line Items Unique to Captive Insurers

Form BIRS7 contains line items specific to captive insurers, absent from standard computations:

Risk Retention Adjustment: Report the amount of risk retained by the captive versus ceded to reinsurers. The Inland Revenue Department uses this to confirm the captive genuinely bears risk and is not a fronting arrangement.

Parent Company Premium Adjustment: If premiums charged to the parent company are not at arm's length, the Inland Revenue Department may adjust the premium income. The form requires disclosure of the premium pricing basis and any related party transactions.

Captive Insurance Business Only: Segregate income and expenses attributable to the captive insurance business from any other activities. If the captive also writes third-party policies, those profits must be computed separately on a standard profits tax computation.

Filing Through the Business Tax Portal

The Inland Revenue Department encourages electronic filing through the Business Tax Portal. For authorized captive insurers in multinational enterprise groups, mandatory electronic filing applies from the year of assessment 2025-26. Register for the Business Tax Portal and obtain the necessary credentials to submit the return.

Upload Form BIRS7 as a separate attachment to the BIR51. The form must be in an acceptable format, such as PDF or iXBRL. Verify the form is complete and signed before submission.

Record Keeping and Compliance

Maintain proper books and records for at least seven years after the end of the relevant year of assessment. Records must include the captive insurance policies, premium invoices, claims files, reinsurance contracts, and investment records. The Inland Revenue Department may conduct a field audit to inspect these records.

Retain a copy of Form BIRS7 and the supporting tax computation. If the Inland Revenue Department raises queries, be prepared to provide a detailed explanation for each line item.

Relationship with Other Tax Forms

Form BIRS7 is a supplementary form to the BIR51. It is not filed separately and must be attached to the profits tax return. Do not use Form BIRS7 for other purposes, such as claiming deductions for research and development expenditure (Form BIRS3) or energy efficient building installations (Form BIRS4). Those claims require separate supplementary forms.

Form BIRS7 is distinct from Form BIRS6, used by professional reinsurers. A captive insurer that also writes reinsurance for third parties may need to complete both forms, but the captive insurance business must be computed on Form BIRS7.
