STP Finalisation and Payday Super Requirements for Australian Businesses
Single Touch Payroll (STP) finalisation and Payday Super are two important payroll compliance obligations for Australian employers. Understanding the requirements, key deadlines, and reporting obligations can help businesses maintain accurate payroll records and meet their obligations with the ATO.
For small businesses in Melbourne and across Australia, keeping up with changes to STP reporting, superannuation obligations, and broader payroll compliance requirements can be challenging. With the STP finalisation deadline and the introduction of Payday Super, it's important for employers to review their payroll processes and ensure they remain compliant with current ATO requirements.
STP finalisation: the 14 July cut-off
Every employer reporting through Single Touch Payroll must make an end-of-year finalisation declaration. This is what tells the ATO your employees' payroll data for the year is complete and correct, so they can lodge their tax returns.
The STP finalisation deadline is 14 July each year. If you can't finalise by then, you'll need to apply to the ATO for a deferral, you can't simply let it lapse. (Employers with closely held payees may have different due dates.)
ATO reference: End-of-year finalisation through STP. Also known as the STP finalisation deadline, this is a key payroll compliance requirement in Australia.
Getting this right matters: incorrect or late STP finalisation can hold up your employees' tax returns and flag your business with the ATO.
Payday Super: what's changing from 1 July 2026
From 1 July 2026, the way you pay super changes completely. Instead of paying the super guarantee quarterly, you now need to pay it every payday, at the same time as wages.
The key things to know:
- Super must reach your employees' funds within 7 business days of each payday (limited exceptions apply, such as for new starters).
- Super is calculated on qualifying earnings, a broader base than before, still at the 12% rate.
- The Small Business Superannuation Clearing House SHSCH) has now closed, so if you relied on it, you'll need an alternative way to pay super.
- Missing the new deadlines triggers the super guarantee charge (SGC), assessed directly by the ATO.
These Payday Super changes in Australia significantly impact cash flow and payroll processes. And this is one of the biggest payroll compliance changes for Australian small businesses in recent years.
Who should you actually go to for help?
You don't have to work this out alone. The right person depends on what you need:
- A registered BAS agent or bookkeeper, for day-to-day payroll, STP lodgement, finalising your year, and setting up compliant Payday Super processes (ideal for small businesses needing hands-on payroll compliance support in Melbourne and across Australia)
- Your payroll software provider, to make sure your system is configured for Payday Super and STP Phase 2.
- Your accountant or registered tax agent, for tax strategy and complex structuring questions.
- The ATO website, for the official rules though it won't do the lodging for you.
Keeping Payroll Compliance on Track
STP finalisation is due by 14 July, while Payday Super is now part of ongoing payroll obligations for Australian employers.
Businesses that maintain accurate payroll records, review their processes regularly, and ensure their payroll systems are configured correctly will be better positioned to meet these requirements and avoid unnecessary compliance risks.
Understanding your obligations around STP finalisation, Payday Super, super guarantee payments, and payroll compliance is becoming increasingly important as payroll reporting requirements continue to evolve. Employers should regularly review ATO guidance and their internal processes to support ongoing compliance.
