There are 3 instances where you will pay tax on your yearly SMSF Tax return:
1. ATO Supervisory Levy – Each year when your tax return is lodged your fund is required to pay a supervisory levy to the ATO of $259. Note that new funds in their first year need to pay this amount twice when lodging their first tax return, then once a year from then on.
2. Income, Dividends & Contributions / Expenses & Fees – All the income into your fund from employer contributions, personal contributions (up to a certain amount) and dividends is taxed at 15%. The taxable amount is offset by any expenses and fees your fund paid throughout the year. (eg accounting fees, hardware wallet etc)
3. Capital Gains / Capital Losses – Any time a single asset is sold for a profit. eg you buy a coin for $1 and then you sell the coin for $10, you are taxed on the $9 profit you made.
15% tax if held for less than 12 months, 10% tax if held for more than 12 months.
If you make a loss on the sale of an asset, your loss will be offset against your gains.
