- GST-registered businesses in Singapore must keep proper business and accounting records for at least 5 years to support GST declarations.
- Records should cover income, purchases/business expenses, imports/exports, rental agreements, payment evidence, and any transactions affecting output tax or input tax.
- Businesses should also keep supporting documents for special cases, such as private use of business assets, asset disposal, customs warehouse removals, and checks for missing trader fraud.
- Helpful summary records include bank statements, stock lists, general ledgers, financial statements, and sales/purchase listings.
- Electronic records are allowed without special approval if record-keeping requirements are met; failure to keep records may lead to disallowed GST claims or penalties.
