- Records must be kept seven years from the date of each transaction, not the year end
- Section 51C binds sole proprietors too, not only incorporated companies
- Record-keeping duties continue after the business stops trading
- Scans can replace paper originals if a responsible person supervises the process
Hong Kong record keeping requirements don’t use one universal seven-year clock. Every person carrying on a trade, profession or business has a tax-record duty under section 51C of the Inland Revenue Ordinance. Hong Kong companies have a separate accounting-record duty under the Companies Ordinance.
That distinction changes when you may destroy a document. Sole proprietors and partnerships usually work from the transaction date. A company should calculate both applicable dates and retain the record until the later one has passed.
In this guide, you’ll learn:
- which law applies to your business;
- how to calculate the two retention dates; and
- when cloud records, scanned copies and secure destruction are allowed.
Which record-keeping rules apply to your Hong Kong business?
Section 51C applies to every person carrying on business, while Companies Ordinance sections 373 to 377 add a separate duty for incorporated companies. Payroll, MPF and corporate registers can carry their own rules too.
| Your situation | IRO s.51C | Companies Ordinance | Practical result |
|---|---|---|---|
| Sole proprietor or partnership | Yes | No | Keep sufficient business records under the transaction-based tax clock. |
| Trading limited company | Yes | Yes | Calculate both seven-year clocks and use the later disposal date. |
| Dormant limited company | Only if it is carrying on business or has relevant business transactions | The company-law framework still matters | Keep evidence of dormant status and any permitted transactions. |
| Business has stopped trading | Existing records remain subject to the unexpired period | The duty continues while the company exists | Cessation is not the same as dissolution. |
| Company has been dissolved | Current BIR51 instructions may end the s.51C period if sooner | Former-director duties can continue under s.758 | Do not destroy the books merely because deregistration completed. |
The Inland Revenue Ordinance section 51C test is whether the records let assessable profits be readily ascertained. It applies to sole proprietors, partnerships and companies carrying on business.
For companies, section 373 of the Companies Ordinance requires records that:
- show and explain the company’s transactions;
- disclose its financial position and financial performance with reasonable accuracy; and
- let the directors ensure the financial statements comply with the Ordinance.
The company-law responsibility sits with the directors. This is separate from the tax duty, even though many of the same invoices, bank records and ledgers satisfy both.
Statutory registers are outside this article. The Significant Controllers Register has separate keeping and inspection rules.
What business and accounting records do you have to keep?
Keep the books and source documents needed to trace each material transaction from evidence to ledger and financial statements. A bank statement alone isn’t enough if it only shows net cash without explaining the transaction.
The IRD record-keeping guidance names:
- books of account recording receipts and payments, or income and expenditure;
- vouchers, bank statements, invoices, receipts and other supporting papers;
- records of business assets and liabilities;
- day-by-day records of money received and spent;
- lists of debtors and creditors; and
- year-end inventory statements and stocktaking records.
What if your business sells goods?
Goods businesses need enough detail to verify what was purchased or sold, its value and the parties involved.
Keep records such as:
- purchase and sales invoices;
- quantities and values of goods;
- seller and buyer details where required;
- inventory statements; and
- the stocktaking records supporting the year-end inventory figure.
Cash retailers have a limited concession. A shop normally conducted in cash doesn’t have to identify every buyer for every sale. It must still keep full purchase records and day-by-day records of all money received and spent.
What if your business provides services?
Service businesses need records that show what was supplied and support the amount charged. That normally means proposals or engagement terms, invoices, time or delivery evidence, customer records, expense support and proof of payment.
The law doesn’t prescribe one bookkeeping application. It asks whether the profits and company position can be reconstructed accurately. Who performs each bookkeeping duty is a separate operational choice.
The reporting period still matters because choosing a financial year end determines the company-law clock and the accounts these records support.
How long must you keep Hong Kong business records?
The minimum is generally seven years, but the starting date depends on the law. Companies should calculate both clocks rather than applying the transaction date to everything.
| Rule | Seven-year clock starts | Who it covers |
|---|---|---|
| IRO s.51C | Completion or date of the transaction, act or operation concerned | Every person carrying on a Hong Kong trade, profession or business |
| Companies Ordinance s.377 | End of the financial year containing the last entry or recorded matter | Hong Kong companies |
The IRD guide to keeping business records uses the transaction date. Companies Ordinance section 377 instead runs for seven years after the relevant financial year ends.
Worked example: one invoice, two disposal dates
Assume a company issues an invoice on 15 March 2026 and has a 31 December financial year end:
- Tax clock: retain it until at least 15 March 2033.
- Company clock: the invoice sits in the year ending 31 December 2026, so retain it until at least 31 December 2033.
- Practical disposal date: use 31 December 2033, subject to any longer audit, tax-loss, dispute or litigation hold.
This approach is easier to administer than deleting individual documents every day. Set a disposal date by record batch, based on the latest legal date in that batch.
What happens when the business closes?
Stopping trade doesn’t stop an unexpired retention period. The IRD says the duty continues after cessation until the relevant seven years have passed.
Dissolution is different. Current BIR51 instructions state that a corporation keeps its tax records for seven years after the transactions, or until dissolution if sooner. However, Companies Ordinance section 758 requires every person who was a director immediately before dissolution to ensure the company’s books and papers are kept for at least six years after dissolution.
If you are closing down a Hong Kong company, assign custody before deregistration finishes. Record who holds the archive, where it is stored and when each category may be destroyed.
What are the penalties for poor record keeping?
The two laws carry different exposure.
- Under the IRO, failing to keep sufficient records without reasonable excuse can attract a maximum HK$100,000 fine.
- Under section 377, a director who fails to take all reasonable steps to secure compliance can be fined HK$300,000.
- Wilful failure under section 377 can bring the same HK$300,000 fine plus up to 12 months’ imprisonment.
Poor records also make an estimated assessment or IRD enquiry harder to challenge.
Where may a company keep its accounting records?
A company may keep accounting records at its registered office or another place chosen by the directors, including outside Hong Kong if the statutory safeguards are met. Cloud storage doesn’t transfer responsibility to the software provider.
Under Companies Ordinance section 374:
- records must be available for directors to inspect at all times without charge;
- if the records are outside Hong Kong, accounts and returns about that business must be sent to and kept in Hong Kong;
- those Hong Kong accounts and returns must show the financial position with reasonable accuracy at intervals of no more than six months; and
- they must be sufficient for directors to ensure the financial statements comply with the Ordinance.
For cloud records, keep:
- administrator access in the company’s control;
- regular exports in a durable, readable format;
- backups separate from the main platform;
- an audit trail showing changes and approvals; and
- an exit plan for changing accountants or software.
The IRD can require records within the taxpayer’s possession or control. A file held by an accountant, overseas group company or cloud provider may still be within your control if you can obtain it.
Can you digitise records and destroy the paper?
Yes, for tax purposes, compliant electronic records can replace paper source documents. That doesn’t mean every signed original can be destroyed for every legal or commercial purpose.
Section 8 of the Electronic Transactions Ordinance requires retained electronic information to:
- remain accessible for later reference;
- stay in its original format, or a format that accurately represents the original information; and
- preserve information identifying its origin, destination, and sending or receipt time.
The IRD guidance on electronic business records also recommends:
- reliable assurance that the information remains complete and unaltered;
- clear, legible reproduction;
- suitable file formats and backup procedures; and
- scanning, storage and disposal undertaken or supervised by a responsible person in the organisation.
That last point is IRD recommended practice, not the text of section 8 itself. It is still the safest operating standard because it creates accountability for scan quality, custody and destruction.
Keep the original where another rule or transaction requires it. Deeds, share certificates, negotiable instruments and filings requiring original signatures need separate review. The broader position sits with whether electronic records are valid in Hong Kong.
When should you keep records for longer than seven years?
Keep records longer where another legal period, an unresolved matter or a continuing business purpose requires them. Seven years is a minimum, not an automatic destruction command.
Common reasons for a longer hold include:
- an open IRD audit, objection, appeal or investigation;
- litigation, a threatened claim or a contractual dispute;
- carried-forward tax losses that are still being used;
- ownership, property or financing documents with continuing effect;
- an auditor’s unresolved request; or
- another regulatory retention period.
The IRD recommends retaining records supporting tax losses until seven years after those losses have been fully set off.
Personal data shouldn’t be kept forever merely because it once appeared in a business file. The Privacy Commissioner’s retention guidance recognises the section 51C requirement, but personal data should be erased once no legal requirement or continuing purpose remains.
Use a written retention schedule with:
- the record category;
- the governing rule;
- the retention start and disposal dates;
- any active legal hold;
- the storage owner; and
- the destruction method and log.
What about payroll records?
Payroll documents may sit under more than one clock. The tax and accounting copies may need seven-year retention, while the Labour Department’s wage-record rule requires the preceding 12 months of each employee’s wage and employment history, plus another six months after employment ends.
The shorter employment-law period doesn’t override a longer tax, accounting, MPF, audit or dispute requirement.
How Sleek helps with bookkeeping and record keeping
Most businesses do not have a record-keeping problem. They have a bookkeeping problem that shows up as one at year end, when the documents needed to verify the books turn out to be scattered across three inboxes and a drawer.
With Sleek you get:
- Books kept as you go, so the day-by-day record the IRD asks for exists without a year-end reconstruction
- Documents captured and filed against the transactions they support, which is what “underlying documentation” means in practice
- Accounting and tax filing services built on those same records
- Statutory audit services where your company needs one, working from records that were organised before the auditor asked
You remain responsible for the records, but you don’t have to build the system or chase every missing document alone.

FAQs on hong kong record keeping requirements
Do emails, WhatsApp orders and marketplace exports count as business records?
Yes, when they evidence a transaction or help trace it through the accounts. An order message, platform sales export or delivery confirmation may support who bought what, what was supplied and the amount charged. Save it in a durable format linked to the transaction rather than relying on indefinite access to an app or chat account.
What should I export before changing accounting software or accountants?
Export the general ledger, trial balance, transaction detail, chart of accounts, bank reconciliations, invoices, bills, attachments, fixed-asset register and audit trail. Keep the exports in readable formats together with a backup of source documents. Confirm that your company retains administrator access before the old subscription or accountant’s access ends.
Can Hong Kong business records be kept in Chinese?
Yes. Section 51C permits sufficient income and expenditure records in English or Chinese. The records still need to make assessable profits readily ascertainable. If source documents use another language, keep enough translation or explanation for the company, accountant, auditor and IRD to understand the transaction without reconstructing it from memory.
What if carried-forward tax losses are older than seven years?
Keep the supporting loss-year records longer. The IRD recommends retaining them until seven years after the losses have been fully set off against later profits. Destroying the evidence while the losses are still being claimed can leave you unable to support the amount when the IRD reviews a later Profits Tax Return.
