In case you didn’t already know, when a new employee joins your
company, you must provide them with the ATO’s Superannuation Standard Choice form (or your own equivalent) within 28 days.
If your new employee doesn’t fill out the form, they're
automatically linked or 'stapled' to the super fund they're already
in (if they already have one). As their employer, it's important
that you check with the ATO whether your new employee has a stapled
fund and if they do, make contributions into that same fund, not
your default fund.
If they do fill out the form and choose a different super fund,
including your default fund, you should pay their contributions into
that fund instead of their stapled fund.
