What Is Payday Super?
Since 1 July 2026, super is paid with wages, not quarterly. Each employee's super must reach their fund within 7 business days of payday (20 business days for a new employee's first contribution). It's the biggest change to super in a generation, and it changes how construction businesses manage cash flow.
The quarterly buffer is gone. A builder paying fortnightly now makes 26 or more super payments a year instead of four.
Why This Hits Construction Harder Than Most Industries
- Lumpy cash flow. Builders and subbies often wait 30, 60 or even 90 days for progress payments. Under the old quarterly system you could time super around when money came in. That flexibility is gone.
- Variable workforces. Crews grow and shrink project by project. More workers on site means more super, more often, with less notice. Your payroll system needs to handle it automatically.
- Subcontractor confusion. Labour-only subbies can be owed super even with an ABN. If some of yours are really employees, late super now costs more. See do I have to pay super for my subbies?
- The SBSCH has closed. The Small Business Superannuation Clearing House shut on 1 July 2026. If you relied on it, you need another way to pay super now.
The ATO's First-Year Compliance Approach
The ATO has set out its first-year approach in PCG 2026/1. The short version: if you're genuinely trying to get it right and fix problems quickly, you won't be the focus of enforcement.
Businesses that make no effort, ignore deadlines or have a history of late super should expect scrutiny. If you still haven't switched over, don't wait for a letter.
If You Haven't Switched Over Yet
- Check your payroll software pays super with every pay run and reports through STP Phase 2.
- Replace the SBSCH if you were still using it.
- Review your subbies. Labour-only subbies need super too.
- Hold a cash buffer of one to two pay cycles of super.
- If any super has gone in late since 1 July, tell the ATO before it contacts you.
Cash Flow Modelling: A Practical Example
Consider a residential builder in Perth with 8 employees on a fortnightly pay cycle. Total fortnightly wages are $32,000. At the 12% SG rate, super per fortnight is $3,840.
Under the old system, this builder built up roughly $24,960 in super over a quarter and paid it in one lump sum by the 28th of the following month. Under Payday Super, that $3,840 leaves the account every two weeks - whether or not a progress claim has been paid.
If your business regularly carries 30 to 60 days of receivables, keep at least one to two pay cycles of super in your operating account at all times. For this example, that's roughly $4,000 to $8,000 in reserve.
What Happens If You Pay Late?
If super doesn't reach the fund within 7 business days, you're liable for the super guarantee charge. For earnings from 1 July 2026 it is made up of:
- The unpaid super.
- Notional earnings: interest at the general interest charge rate, compounding daily.
- An administrative uplift that starts at 60% of the shortfall and interest. It can be cut, potentially to nil, if you own up before the ATO comes to you.
- A choice loading of 25%, capped at $1,200, if you ignored an employee's choice of fund.
The good news: these amounts are now tax deductible. The bad news: interest on a late-paid charge and late payment penalties aren't, and directors can be made personally liable through a director penalty notice.
Key Takeaways for Builders and Contractors
Payday Super is live. Treat super like wages: it leaves the account every pay run, whether or not the progress claim has landed. Price it into your rates, hold a buffer, and fix any late payments yourself before the ATO finds them.
