Introduction
How long must you keep accounting records in Singapore and in what form? This is a common question for business owners and company directors preparing for audits, GST obligations or routine compliance checks.
In this article, How Long Must You Keep Accounting Records in Singapore and in What Form? we summarise the key obligations under the Companies Act, IRAS rules and other Singapore requirements, explain acceptable formats, and provide practical steps for managing retention. This guidance is general in nature; for advice tailored to your circumstances, contact a professional adviser such as Raffles Corporate Services.
Who this applies to
This guidance applies to:
- Private and public companies incorporated in Singapore (including those formed via company incorporation Singapore processes).
- Sole proprietors and partnerships carrying on business in Singapore.
- GST-registered businesses and employers with CPF and payroll obligations.
- Directors, company secretaries and finance teams responsible for statutory records, minute books and accounting systems.
Key rules and requirements in Singapore
There are several overlapping obligations to consider. The headline points below are based on guidance from ACRA, IRAS, MOM, CPF Board and other regulators.
Companies Act and statutory records
The Companies Act requires companies to keep accounting records that sufficiently explain transactions and allow a company’s financial position to be determined. Directors and the company secretary must ensure records are maintained and available for inspection. In practice, many companies retain key accounting records for at least five years from the end of the relevant Financial Year End, though some documents may need to be kept longer where necessary for audits, disputes or specific legal requirements.
IRAS (income tax and GST)
IRAS expects businesses to keep tax-related records, including supporting documents for tax computations and GST returns. For most tax and GST purposes, businesses should retain records for five years from the relevant Year of Assessment or the date of the GST return. Where there are ongoing enquiries or investigations, IRAS may request older records.
Payroll, CPF and Employment obligations
Payroll records supporting CPF contributions, salary payments and leave should be retained to demonstrate compliance with CPF and Employment Act obligations. These records are important in the event of CPF or MOM inspections and for tax-reporting purposes.
Format: electronic or paper
Singapore regulators generally accept electronic records provided they are accurate, complete, accessible and capable of being produced in legible form. Key considerations:
- Records must be stored on secure, reliable systems with appropriate backups.
- Electronic records should remain readable for the retention period and convertible to hard copy if requested (e.g. by IRAS or ACRA).
- Consider PDPA obligations when storing personal data electronically.
Step-by-step process
Establishing a clear retention policy reduces risk and improves operational efficiency. Below is a practical, step-by-step approach.
- Identify categories of records
- Examples: accounting ledgers, invoices, receipts, bank statements, payroll records, GST returns, contracts, statutory registers and minutes.
- Determine retention periods
- Apply the minimum statutory retention periods (commonly five years for tax/GST-related materials) and extend where other laws or commercial considerations require it.
- Choose storage methods
- Decide on electronic, paper, or hybrid storage. Ensure systems are secure, backed up and accessible for retrieval and audits.
- Implement access controls
- Limit access to authorised personnel, log access where appropriate and comply with PDPA requirements for personal data.
- Document your disposal policy
- Define approved disposal methods, retention triggers and maintain a disposal log for destroyed records.
- Review regularly
- Update retention schedules when laws change or business needs evolve. During audits or disputes, retain records beyond the usual period.
Common mistakes to avoid
- Destroying records too early — do not delete records simply because the minimum period has passed if audits or disputes are possible.
- Poor backup and security of electronic records — data loss or corruption can lead to compliance failures.
- Mingling personal and company records — maintain clear separation to avoid accounting and tax issues.
- Failing to keep supporting documents for GST claims or tax deductions.
- Assuming paper originals are always required — electronic formats are acceptable if properly maintained and producible.
Practical examples
These examples illustrate typical retention choices. They are illustrative only; apply to your facts and seek advice for particular situations.
- Small private company (non-GST)
Keep accounting ledgers, bank statements, invoices and corporate minutes for at least five years after the Financial Year End. Retain minute books and statutory registers as required by the Companies Act and ACRA guidance.
- GST-registered business
Retain GST tax invoices, import/export documents and GST returns for at least five years from the end of the accounting period covered by the GST return, or longer where IRAS demands.
- Employer with CPF obligations
Keep payroll records, CPF contribution statements and related documents for at least five years to support CPF and tax filings and to respond to CPF Board queries.

Frequently Asked Questions
How long must a sole proprietor keep accounting records?
Sole proprietors should retain business records for tax and audit purposes — typically for a minimum of five years from the relevant Year of Assessment. Specific situations may require longer retention; consult IRAS guidance.
Are electronic records acceptable to ACRA and IRAS?
Yes. Both ACRA and IRAS accept electronic records provided they are accurate, complete, readily accessible and can be produced in legible form for the required retention period.
What if my company is under audit or investigation?
If an audit or investigation is ongoing or reasonably foreseeable, retain all relevant records until the matter is resolved. Do not destroy documents that may be relevant to enquiries by IRAS, ACRA, MOM or other authorities.
Can I securely dispose of old records once the retention period has passed?
Yes, but follow a documented disposal policy. For sensitive or personal data, use secure destruction methods and maintain a disposal log. Consider whether any contractual, tax or regulatory reasons require longer retention before disposal.
Key takeaways
- Keep accurate accounting records to satisfy the Companies Act and to support tax, GST and payroll compliance.
