Hong Kong Tax Computation Submission
Mandatory Submission: Hong Kong Profits Tax Computations 🇭🇰💰
Tax computations must be submitted together with the Profits Tax Returns (PTR) to the Hong Kong Inland Revenue Department (IRD) for most corporations and partnership businesses that have gross income.
The tax computation is a critical document that explains how the assessable profits (or losses) are calculated, starting from the company's accounting profit/loss and making the required adjustments under the Inland Revenue Ordinance.
Navigating Hong Kong Profits Tax compliance requires meticulous preparation, and a key mandatory step is the submission of Tax Computations alongside your annual Profits Tax Return (PTR). This document acts as the bridge, translating your company's accounting results into figures that comply with Hong Kong's tax laws.
Why Tax Computations are Mandatory
The requirement for tax computations stems from the need to reconcile a company’s financial statements, which are prepared according to standard accounting principles, with the specific rules of the Inland Revenue Ordinance (IRO).
Reconciliation: The tax computation shows the precise adjustments made to the accounting Net Profit or Loss to arrive at the Assessable Profits (the amount subject to Profits Tax).
Compliance: It serves as the primary evidence to the IRD that the company has adhered to all tax-deductibility rules, depreciation allowances, and non-taxable income exclusions.
Key Supporting Documents Required
For most corporations and partnership businesses, the PTR must be accompanied by the following Supporting Documents:
Audited Financial Statements: This typically includes the Balance Sheet (Statement of Financial Position), Profit and Loss Account (Statement of Comprehensive Income), and the Auditor's Report, signed by a Certified Public Accountant (CPA) in Hong Kong.
Tax Computation: A detailed schedule showing the adjustments from accounting profit/loss to assessable profits/losses.
Supplementary Forms (if applicable): Forms relating to specific tax incentives, transfer pricing, or preferential tax regimes.
What the Tax Computation Must Detail
The document is essentially a step-by-step breakdown. It typically includes schedules for:
Non-Deductible Expenses: Adding back expenses charged in the accounts that are not allowed for tax purposes (e.g., capital expenditure, certain donations, private expenses).
Non-Taxable Income: Deducting income included in the accounts that is exempt from Profits Tax (e.g., offshore profits, capital gains, dividends).
Tax Allowances: Calculating and deducting depreciation allowances (formerly called "wear and tear allowances") for plant, machinery, and industrial or commercial buildings, which are calculated based on tax law, not accounting depreciation.
Submission Methods and Formatting
The IRD encourages electronic filing, and the format for submitting the tax computation depends on the filing method chosen.
Filing Method | Profits Tax Return (PTR) | Tax Computation Format |
Electronic Filing (e-Filing) | Submitted via the IRD's e-Tax Services | iXBRL (Inline eXtensible Business Reporting Language) format is mandatory for most large and medium-sized corporations. |
Paper Filing | Print and submit the paper form | Can be submitted in paper form (typically attached to the printed PTR). |
Electronic Submission with iXBRL
The IRD has progressively rolled out mandatory iXBRL filing for financial statements and tax computations. This structured data format allows for automated processing. Taxpayers must ensure their data files conform to the IRD Taxonomy Package.
Profits Tax Filing Deadlines
The standard deadline for filing the Profits Tax Return is one month from the date of issue. However, most businesses engage a tax representative and benefit from the Block Extension Scheme, which grants extended due dates based on the company’s financial year-end date.
Failure to submit the Profits Tax Return, along with the required tax computation and financial statements, by the due date may result in a penalty, estimated assessment, or even prosecution.

1. Expert Preparation of Tax Computations
The tax computation is the core of your submission. Bestar's tax experts ensure this document is flawlessly prepared, converting your accounting results into assessable profits according to the Inland Revenue Ordinance (IRO).
Statutory Adjustments: We meticulously identify and adjust for the difference between accounting principles (HKFRS/SME-FRS) and tax law.

Maximizing Allowances: We ensure the accurate calculation and full claim of all eligible depreciation allowances (formerly 'wear and tear allowances') for plant, machinery, and industrial/commercial buildings, which are often different from accounting depreciation.
Offshore Claim Support: For businesses operating under Hong Kong's territorial tax system, we prepare the necessary supporting schedules and documentation to substantiate claims for offshore profits tax exemption, a critical and often high-risk area of compliance.
2. Compliance with IRD's Digital Filing Mandate (iXBRL)
The IRD is moving towards mandatory electronic filing, requiring many businesses to submit financial statements and tax computations in the highly technical iXBRL (inline eXtensible Business Reporting Language) format.
iXBRL Conversion Service: Bestar converts your financial statements and tax computations into the precise iXBRL data files required by the IRD's e-Tax system. This eliminates the technical burden on your in-house team and prevents submission errors from incorrect tagging.

Beyond mere compliance, Bestar works to optimize your tax position under Hong Kong's low-tax regime.
