Payday Super is a good reminder to review your SMSF investment frequency

From 1 July 2026, employers must pay superannuation guarantee (SG) contributions with every pay cycle rather than quarterly. For most Australians, Payday Super is straightforward good news – contributions land in their fund sooner and have longer to compound.

For self-managed super fund (SMSF) trustees, though, the change is not so straightforward. Not because it creates a compliance problem, but because it changes a fundamental assumption most SMSFs have been operating on for years: that contributions arrive four times a year in predictable, reasonably sized parcels.

Under Payday Super, the same annual contribution lands in the fund’s bank account as a series of smaller, more frequent deposits. A member on a $100,000 salary receiving 12% SG will still accumulate $12,000 in employer contributions over the year. But instead of $3,000 arriving quarterly, they’ll receive roughly $1,150 per month (on a monthly pay cycle), $575 if they’re paid per fortnight, or $277 if they’re paid weekly.

That’s a meaningful change for any trustee who hasn’t consciously thought about their investment frequency.

The cash drag problem

Unlike members of large industry funds, where contributions are automatically swept into an investment option on receipt, SMSF contributions land in the fund’s bank or cash account and sit there until the trustee acts. No one invests the money automatically. That’s the whole point of the SMSF structure – control rests with the trustee.
