Hong Kong Profits Tax Filing Guide
Hong Kong Profits Tax Filing Guide
Under Section 51 of the Hong Kong Inland Revenue Ordinance (IRO), corporations and active businesses must submit their Profits Tax Return (BIR51/BIR52) accompanied by supporting financial statements and a tax computation.
Preparing the required financial statements and tax computation is a critical step in fulfilling your tax compliance obligations with the Hong Kong Inland Revenue Department (IRD).
📌 Checklist: Required Attachments for Hong Kong Profits Tax Filing
When filing your Profits Tax Return with the IRD, prepare and submit three primary deliverables:
[ Signed Profits Tax Return ] + [ Financial Statements ] + [ Tax Computation ]
(BIR51 / BIR52) (Audited / Unaudited) & Supporting Schedules
1. The Signed Profits Tax Return (BIR Form)
Form BIR51: For corporations (limited companies).
Form BIR52: For partnerships and non-corporate entities.
Form BIR54: For non-resident individuals or businesses.
2. Financial Statements (Audited Accounts)
For incorporated limited companies, financial statements must be audited by an independent Certified Public Accountant (CPA) licensed in Hong Kong. Your financial statement submission pack must include:
Auditor’s Report: Signed by your Hong Kong CPA.
Statement of Financial Position (Balance Sheet).
Statement of Comprehensive Income (Profit & Loss Account).
Notes to the Financial Statements: Disclosing accounting policies, related-party transactions, and capital structure.
Audit Exemption Exceptions: Small sole proprietorships/partnerships, dormant companies (under Cap. 622), and certain Hong Kong branches of foreign companies with specific disclosures are exempt from attaching audited accounts.
3. Profits Tax Computation & Schedules
Accounting net profit is rarely identical to taxable assessable profit. The tax computation acts as the mathematical bridge connecting your audited financial statements to your taxable profit.
Your tax computation package must include:
Taxable Profit / Adjusted Loss Calculation: Reconciling Net Profit before tax to Assessable Profits.
Depreciation Allowances Schedule: Calculating commercial depreciation add-backs versus tax-deductible capital allowances (Industrial/Commercial Building Allowances, Annual Allowances).
Non-Deductible Expense Schedule: Listing items added back to taxable income (e.g., private expenses, capital expenditures, fine penalties).
Non-Taxable Income Schedule: Deducting capital gains, offshore income claims, and tax-exempt dividends.
Tax Loss Carried Forward Schedule: Tracking tax losses from previous years used to offset current-year profit.
🧮 How Book Profit Becomes Taxable Assessable Profit
Step | Adjustment Type | Purpose |
1. Net Accounting Profit | Base Figure | Taken directly from audited Profit & Loss statement. |
2. Add-Backs | + Add Non-Deductible Items | Reverts accounting depreciation, non-business costs, and capital losses. |
3. Deductions | - Subtract Offshore/Capital Gains | Excludes offshore income, capital profits, and tax-exempt dividends. |
4. Capital Allowances | - Subtract IRD Statutory Allowances | Replaces accounting depreciation with IRD statutory capital allowances. |
5. Loss Offsets | - Subtract Prior Losses | Applies unabsorbed tax losses carried forward from previous years. |
= Net Assessable Profit | Final Tax Base | Basis for two-tiered tax rate calculation (8.25% / 16.5%). |
⚙️ Modern Tax Filing Formats: iXBRL and XML Rules
Hong Kong IRD accepts both paper and e-filing submissions, with digital filing required for specific corporate entities:
Financial Statements & Tax Computations: Must be submitted in iXBRL (inline eXtensible Business Reporting Language) or PDF format depending on the entity tier.
Supplementary Forms (S1–S18): Must be submitted electronically in XML format via the IRD eTAX portal.
Under Section 51 of the Hong Kong Inland Revenue Ordinance (IRO), active corporations and businesses must submit their Profits Tax Return (BIR51/BIR52) accompanied by supporting audited financial statements and a tax computation.
Fulfilling your tax compliance obligations with the Inland Revenue Department (IRD) requires rigorous preparation to align statutory accounting standards with Hong Kong tax laws. Bestar Hong Kong provides end-to-end professional support to manage every aspect of this compliance workflow.
📌 Compliance Checklist: Required Filing Deliverables
When the IRD issues your company's Profits Tax Return, submit three main components:
[ Signed Profits Tax Return ] + [ Audited Financial Statements ] + [ Tax Computation ]
(BIR51 / BIR52) (Per HKFRS / SME-FRS) & Tax Schedules
1. The Signed Profits Tax Return (BIR Form)
Form BIR51: Issued to incorporated limited companies.
Form BIR52: Issued to partnerships and non-corporate entities.
Form BIR54: Issued to non-resident entities earning Hong Kong-sourced income.
2. Audited Financial Statements
Hong Kong limited companies are legally required to undergo an annual statutory audit conducted by an independent Hong Kong Certified Public Accountant (CPA). Your financial submission package includes:
Auditor’s Report: Signed by a licensed Hong Kong CPA.
Statement of Financial Position (Balance Sheet).
Statement of Comprehensive Income (Profit & Loss Account).
Notes to the Financial Statements: Disclosing HKFRS accounting policies and capital structures.
Audit Exceptions: Dormant companies under the Companies Ordinance (Cap. 622) and specific foreign branch operations may be exempt from submitting audited accounts. Small businesses (gross revenue under HK$2 million) are exempt from physically attaching audited accounts to the paper return, but must still have them audited and signed prior to submission.
3. Profits Tax Computation & Schedules
The tax computation bridges accounting profits with statutory assessable profits. Your computation package requires:
Reconciliation Schedule: Adjusting net accounting profit to assessable profit/adjusted loss.
Capital Allowances Schedule: Disallowing accounting depreciation and claiming commercial/industrial building allowances or annual allowances.
Add-Back & Deduction Schedules: Disallowing non-deductible private/capital expenditures and excluding non-taxable offshore income or capital gains.
Tax Loss Schedule: Tracking prior years' unabsorbed tax losses carried forward.
🧮 How Accounting Profit Becomes Taxable Assessable Profit
Step | Adjustment Type | Description |
1. Accounting Net Profit | Base Figure | Extracted directly from audited Profit & Loss statement. |
2. Add-Backs | + Add Non-Deductibles | Restores accounting depreciation, capital losses, and private expenses. |
3. Deductions | - Subtract Offshore/Exempt Income | Deducts offshore profits, tax-exempt dividends, and capital gains. |
4. Capital Allowances | - Subtract IRD Allowances | Replaces depreciation with statutory tax allowances. |
5. Prior Loss Offsets | - Subtract Carried Losses | Applies unabsorbed tax losses brought forward from previous years. |
