Maintaining proper accounting records is a legal requirement in Singapore, not just a good business practice.
Under Singapore regulations, companies are required to maintain accurate and complete accounting records to clearly reflect their financial position and to comply with the requirements of the Accounting and Corporate Regulatory Authority (ACRA) and the Inland Revenue Authority of Singapore (IRAS).
This guide outlines the types of accounting records businesses are required to maintain, the retention periods for these records, and how professional accounting services such as PLCO support compliance and proper organisation.
What Are Accounting Records in Singapore?
Accounting records refer to documents and information that accurately reflect a company’s financial transactions and position.
In Singapore, accounting records must be sufficiently detailed to:
- Capture all income and expenses
- Reflect assets and liabilities
- Support the preparation of financial statements
- Facilitate audits or tax reviews when required
These requirements apply to all types of businesses, including private limited companies, sole proprietorships, and partnerships.
Accounting Records Businesses Must Keep in Singapore
1. Sales and Income Records
Businesses are required to retain documents that demonstrate how revenue is generated, including:
- Sales invoices
- Receipts issued to customers
- Support the preparation of financial statements
- Credit notes and debit notes
These records are essential for verifying declared revenue during tax filing and reviews by the Inland Revenue Authority of Singapore (IRAS).
2. Purchase and Expense Records
Businesses must maintain expense-related documents that clearly reflect the business costs, including:
- Supplier invoices
- Receipts for operational expenses
- Payment vouchers
- Employee reimbursement claims
Proper expense records are essential for accurate tax computation and for substantiating deductible expenses with the Inland Revenue Authority of Singapore (IRAS).
3. Bank Statements and Cash Records
Businesses are required to maintain:
- Bank statements for all business accounts
- Cash books and petty cash records
- Records of electronic payments and transfers
- Bank reconciliation statements
These documents enable proper reconciliation between bank balances and accounting records.
4. Asset and Liability Records
Companies are required to maintain records that reflect their financial position, including:
- Fixed asset registers
- Depreciation schedules
- Loan agreements
- Records of outstanding payables and receivables
These records help ensure that the company’s financial position is accurately presented in its accounts.
5. Payroll and Employment Records
If a business employs staff, it must retain:
- Employment contracts
- Payslips
- CPF contribution records
- Bonus and allowance documentation
These records are essential for ensuring payroll accuracy and compliance with statutory requirements.
6. GST Records (If Applicable)
GST-registered businesses must maintain:
- Tax invoices issued and received
- GST summary reports
- Import and export documentation
- Records supporting zero-rated or exempt supplies
Incomplete or inaccurate GST records may result in penalties or additional assessments by the Inland Revenue Authority of Singapore (IRAS).
How Long Must Accounting Records Be Kept in Singapore?
- Accounting records must be retained for a minimum of 5 years
- The 5-year retention period begins from the end of the relevant financial year
- For businesses that have ceased operations, records must still be kept for 5 years from the date of cessation.
Failure to retain accounting records for the required period may result in fines or enforcement action by the Accounting and Corporate Regulatory Authority (ACRA) and the Inland Revenue Authority of Singapore (IRAS).
Format of Accounting Records – Digital vs Physical
In Singapore, accounting records can be maintained in:
- Physical form
- Electronic or digital format
Regardless of the format, records must be:
- Readable
- Easily accessible
- Properly backed up
- Available upon request by authorities (ACRA / IRAS)
Many businesses engage professional accounting services to maintain secure and organised digital records that meet regulatory standards.
Common Accounting Record-Keeping Mistakes
Some frequent issues faced by businesses in Singapore include:
- Missing source documents
- Mixing personal and business transactions

These mistakes increase compliance risk and may trigger closer scrutiny by IRAS.
