Answer
You might not be able to delete an unused super fund if it is still connected to an employee or an old deposit, but here's how you can at least make it Inactive and get it out of the way.
- Go to Settings >> Super Fund Providers.
- Click Edit Provider beside a fund you wish to get rid of.
- Set the type to Non-compliant Super Fund.
- Enter a fake ABN of 10000000000, which is the number one followed by ten zeroes.
- Untick the Active? box at the bottom.
- Save the changes. The unused fund is now hidden.
To view your hidden/inactive super funds, tick the Show Inactive? box at the bottom of Settings >> Super Fund Providers.
