3.2. Receipts
3.2.1. You can use receipts issued by you to explain your sales transactions. The receipts
must be serially numbered, and a duplicate copy must be retained.
3.2.2. Since July 2003, IRAS does not require businesses to come forward to seek approval for
not issuing receipts. This is part of our efforts to simplify rules and procedures.
Businesses must however ensure complete and accurate recording of their sales
transactions even when they decide not to issue receipts. There must be a welldocumented audit trail to show that all sales transactions are correctly recorded and
declared for tax purposes. Practices such as using a cash register, accounting software,
or a sales book should be maintained to help proper recording of all sales transactions.
3.2.3. It should be noted that in all cases:
(a) You must still issue receipts to customers if requested;
(b) GST-registered businesses must continue to issue tax invoices as required by GST
legislation, as the waiver of issuance of receipts is not the same as a waiver on
issuance of tax invoices.
3.2.4. When making purchases for business purposes, you should ask for a receipt regardless
of whether you pay by cash or cheque. Receipts will help you to support or justify
payments made if disputes arise later.
3.2.5. The details that should be shown on a receipt are:
(a) Date
(b) Name of supplier or service provider
(c) Amount paid
(d) Description of goods or services being paid for.
3.2.6. A receipt from a cash register would generally be sufficient, but it may not always
describe the goods or services that have been paid for. If it doesnt contain sufficient
details, an additional notation should be recorded on the receipt.
3.3. Invoices
3.3.1. If you issue a sales invoice, the sales invoice should contain the following information:
(a) Your name/Business name, address, telephone number and business registration
number;
(b) The date of issue of the invoice;
(c) An identifying number, e.g. invoice number;
(d) Your customers name & address;
(e) The description of goods or services, quantity and price;
(f) Any cash discount offered;
(g) The total price.
3.3.2. You may design your own invoices and get them printed or buy pre-printed invoices from
stationery suppliers.
