Records to verify income and claims for deduction include:

  • For sales: cash register tape, daily sales record book and invoices.

However, you need not forward these records unless they are requested by IRAS. The term 'accounts' refer to the trading and profit and loss accounts as well as the balance sheets.

However, you need not issue receipts if you adopt practices that can ensure the completeness and accuracy of the recording of all your sales receipts.
