Every year, employers must complete their Single Touch Payroll (STP) finalisation. But when exactly is the deadline, and why does it matter so much?
If you miss the deadline, your employees may not have their income statements ready in time for tax season. This could delay their tax returns and cause frustration. For business owners, late or incorrect lodgements can result in penalties and extra work to fix mistakes.
Many employers think that simply reporting each pay run is enough, but the STP finalisation step is different. It confirms to the ATO that your payroll records for the financial year are complete and correct.
What You Need to Know
The Deadline
For most employers, the STP finalisation deadline is 14 July each year.
If you have closely held payees (such as family members or directors paid through the business), you may have until 30 September.
This means you need to ensure all wages, allowances, superannuation and tax withheld are reported and accurate before those dates.
Why It Matters for Your Employees
Your employees rely on you to finalise their records so they can lodge their tax returns on time. Once you finalise, their income statement is marked as “Tax ready” in their myGov account. Without this step, they cannot complete their return properly.
Common Mistakes to Avoid
Forgetting to check that superannuation and allowances are correctly reported.
Missing the deadline and creating unnecessary stress for both you and your employees.
Thinking that the ATO will automatically “know” your records are complete. Finalisation is always required.
Best Practices for Employers
Reconcile payroll figures before the end of June.
Double check allowances, bonuses and fringe benefits have been reported correctly.
Use your payroll software to generate reconciliation reports.
Keep communication open with employees so they know when their records will be ready.
Seek help from your accountant or bookkeeper if you are unsure.
Final Thoughts
The STP finalisation deadline may seem like just another compliance task, but it plays an important role in keeping your employees happy and your business compliant. Preparing early, checking your figures and understanding the deadlines will save you time, stress and money.
