    Review your financial statements including profit and loss statements, balance sheets, and cash flow statements to help identify areas that may need your attention.

  4. Create a list of claimable business expenses
    Pay close attention to expenses you have incurred while running your business that you can include in your tax return.
  5. Prepare for lodgement
    Gather documents for your accountant and get an idea of what your tax outcome might look like.

Good to know

If you need to make payments before 30 June, it’s a good idea to make them 2–3 days early to avoid delays. You might also want to check and update your payment limits ahead of time, in NetBank or the CommBank app.

Are you ready for Payday Super?
