You can generally claim an immediate deduction for operating expenses.

Operating expenses are the expenses you incur in the everyday running of your business. 

General business operating expenses include purchases of trading stock, advertising and sponsorship, legal expenses, bank fees and charges, insurance premiums, stationery, and mobile phone and tablet accessories like protective covers and earphones.

Other expenses (similar to those claimed by employees) includes subscriptions, fees to trade, business or professional associations, expenses relating to education and technical or professional qualifications, and gifts and donations to organisations that have a deductible gift recipient status.

Tax-related operating expenses include registered tax agent and accountant fees.

You can generally claim a tax deduction for most operating expenses in the same income year you incur them. You generally incur the expense when you have a legal obligation to pay for the goods or services. An invoice is usually evidence that an expense has been incurred, but you may have another type of record of the expense.

You can only claim the business portion of these expenses if they are for both business and private use.
