Can I charge a credit card surcharge on invoices?

In Australia you may pass on reasonable card surcharges if disclosed before payment. Show the surcharge as a separate line item, not hidden in the service fee.

Australian tax invoice requirements

A valid Australian tax invoice must show the words “Tax Invoice”, your business name and ABN, the date of issue, a description of the goods or services, the GST amount (or a statement that the total includes GST), and the total price. For sales over $1,000 you must also include the buyer’s identity or ABN.

Register for GST once your turnover reaches $75,000 per year — see ATO: Registering for GST.
