You can, of course, use a personal credit card for your business expenses, especially if you are a sole trader. But this will make your accounting system more complicated. You will need to separate your business and personal expenses each month, and either make two distinct repayments of the balance – one from your personal account and one from your business account – or create a major headache for yourself at the end of the tax year.
Mixing your business and personal expenses may also leave the ATO unconvinced that your business expenses are truly only for business. It’s best to keep them completely distinct by charging them to a separate card, and if it’s a business card you should be able to claim the annual fee as a business expense.
