What Is Payday Super?
From 1 July 2026, employers will be required to pay superannuation guarantee contributions at the same time as wages - not quarterly. This is the biggest structural change to super in a generation, and it fundamentally changes how construction businesses manage cash flow.
Under the current system, if you pay your crew fortnightly, you have until 28 days after the end of each quarter to remit their super. That quarterly buffer disappears on 1 July. Super must be paid alongside every single pay run.
For a builder running a $3M turnover business with 12 employees, this means moving from 4 super payments per year to 26 or more. The cash flow impact is real.
Why This Hits Construction Harder Than Most Industries
Construction businesses face unique pressures that make Payday Super more challenging than it is for, say, a retail shop or an office-based business. Here are the key reasons:
- Lumpy cash flow. Builders and subcontractors often wait 30, 60 or even 90 days for progress payments. Under the current quarterly system, you could time your super payments around when money came in. That flexibility is gone.
- Variable workforces. Construction crews expand and contract project by project. More workers on site means more frequent super payments with less notice. Your payroll system needs to handle this automatically.
- Subcontractor confusion. Many building businesses use a mix of employees and subcontractors. If the ATO determines that some of your subcontractors are actually employees (sham contracting), you could face backdated super liabilities under the new tighter regime.
- The SBSCH is closing. If you currently use the Small Business Superannuation Clearing House to process super payments, it permanently shuts down on 1 July 2026 - the same day Payday Super starts. You need an alternative in place now, not in June.
The ATO's First-Year Compliance Approach
The ATO has released PCG 2026/1 setting out how it will approach compliance in the first year. The short version: if you're genuinely trying to do the right thing and resolve issues quickly, you won't be the focus of enforcement action.
However, businesses that make no effort to transition, ignore deadlines, or have a history of late super payments should expect scrutiny. The ATO has flagged that unpaid small business tax debts now exceed $50 billion, and firmer recovery action is coming across the board.
The ATO's message is clear: prepare now, and we'll work with you. Leave it until July, and you're on your own.
Your 90-Day Action Plan
Here is a practical timeline for construction businesses to follow between now and 1 July 2026:
- Now – April 2026: Audit your payroll software. Confirm it supports STP Phase 2 and can process super with each pay run. If you're using the SBSCH, identify your replacement provider.
- April 2026: Review all contractor arrangements. Ensure you have clear written agreements and that your contractors genuinely meet the ATO's independent contractor criteria.
- May 2026: Build a cash reserve. Model your weekly or fortnightly super obligations and ensure your operating account can cover them between progress payments.
- June 2026: Run a test pay cycle with super included. Process your final quarterly payment through the SBSCH and download all reports before it closes.
- 1 July 2026: Go live. Super must be paid with every pay run from this date forward.
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 11.5% SG rate (from 1 July 2026), super per fortnight is $3,680.
Under the current system, this builder accumulates roughly $23,920 in super over a quarter and pays it in one lump sum by the 28th of the following month. Under Payday Super, that $3,680 must leave the account every two weeks - whether or not a progress claim has been paid.
If your business regularly carries 30–60 days of receivables, you need a cash buffer of at least one to two pay cycles' worth of super obligations sitting in your operating account at all times. For this example, that's roughly $4,000–$8,000 in reserve.
What Happens If You Pay Late?
Late super payments trigger the Super Guarantee Charge, which includes the unpaid super amount, an interest component (currently 10% per annum) calculated from the start of the quarter, and an administration fee of $20 per employee per quarter. These charges are not tax deductible, and the ATO has indicated it will enforce them more strictly under the new regime.
Key Takeaways for Builders and Contractors
Payday Super is not optional and it is not being delayed. The legislation has passed, the ATO guidance is published, and the SBSCH is closing. Construction businesses that act now will transition smoothly. Those that wait until June will face a scramble at the worst possible time - the end of financial year.
Talk to your accountant, review your payroll system, and model your cash flow. Ninety-three days is not as long as it sounds when you're running a building site.
