Single Touch Payroll Finalisation 2026: What Australian Employers and Accountants Need to Do Before 14 July

Why STP finalisation is the most timely Australian accounting topic in April 2026

In April 2026, one compliance issue is moving rapidly onto the radar for Australian accountants, bookkeepers and employers: Single Touch Payroll (STP) year-end finalisation for the 2025–26 financial year. While the finalisation deadline itself lands after 30 June, April is the point where firms should start reviewing payroll data, employee classifications, allowances, super and termination reporting before year-end pressure builds.

This is especially relevant for businesses that have had payroll changes during the year, hired casuals or contractors, paid directors, processed bonuses, or dealt with employee terminations. Errors left until late June often become expensive, time-consuming and highly visible once income statements flow through to employees and the ATO.

For many practices, April is the ideal month to turn STP finalisation from a rushed July clean-up exercise into a controlled compliance process. If this article is read three months from now, the timing will already feel different — because the best window for prevention is right now.

What STP finalisation means for 2025–26

Under STP, employers report salary and wages, PAYG withholding and super information to the ATO each pay cycle through STP-enabled software. At year-end, employers must make a finalisation declaration so the ATO knows the payroll data for each employee is complete and can be used for income tax return pre-fill.

For most closely held payees, there may be concessional reporting options in some circumstances, but for the majority of employers the practical focus is simple: make sure payroll is correct before finalising.

The key deadline most employers work to is:

• 14 July 2026 — standard STP finalisation due date for the 2025–26 year

That date arrives quickly once EOFY work, June BAS, trust resolutions, workpaper completion and tax planning all collide. That is why April matters.

Why accountants should start STP reviews in April, not June

April is often the last relatively manageable point before year-end bottlenecks start. By beginning STP reviews now, practices can identify payroll issues while there is still time to correct them through ordinary pay runs rather than urgent year-end journals and amended reports.

Starting in April helps with:

• reviewing employee setup codes and income types
• checking allowances are classified correctly
• confirming reportable fringe benefits are being tracked for payment summaries via STP income statements where applicable
• reconciling superannuation obligations and clearing house timing
• reviewing termination payments and unused leave treatment
• checking director and shareholder wage reporting
• identifying contractors incorrectly processed as employees, or vice versa
• cleaning up duplicate employee profiles after software migrations or payroll resets

For bookkeepers and small businesses, this early review can also reduce employee frustration. If payroll data is wrong, staff may see incorrect income statements in myGov, which can delay their tax returns and trigger awkward conversations.

The biggest STP problem areas showing up in Australian businesses

1. Incorrect employee categories and income types

One of the most common errors is staff being set up under the wrong category or income type, especially where businesses employ a mix of full-time, part-time, casual, working holiday makers or closely held payees. A setup issue early in the year can affect every pay event lodged after that point.

Action step: review payroll settings for all active and terminated employees before 31 May 2026.

2. Allowances coded as ordinary earnings

Travel allowances, tools allowances, laundry, meals and other payments are often miscoded. Under STP Phase 2 reporting, the ATO expects greater granularity in payroll data. Even where software automates much of the process, the underlying pay item mapping still needs review.

Action step: run a year-to-date payroll summary by earning category and confirm each allowance is mapped correctly.

3. Superannuation timing mismatches

STP does not itself prove super has been paid on time. But year-end payroll reviews often expose unpaid or late super issues. With the super guarantee rate for 2025–26 at 12%, even small payroll errors can compound quickly across a workforce.

Action step: reconcile payroll super accruals to clearing house reports, fund confirmations and general ledger balances.

4. Employment termination payments and leave payouts

ETPs, unused annual leave and long service leave can be mishandled, particularly where businesses process terminations manually or outside their standard payroll workflow. Errors here can affect tax withheld, employee records and finalisation accuracy.

Action step: review all 2025–26 terminations now and verify tax treatment before finalisation season.

5. Duplicate or migrated payroll records

Businesses that changed software, changed payroll providers or imported employee data during the year may have duplicate employee cards or split year-to-date balances. These issues can create incorrect totals in STP reports.

Action step: compare employee master lists, terminated profiles and YTD balances across payroll systems before EOFY processing begins.

April 2026 STP checklist for accountants and bookkeepers

If you manage payroll compliance for clients, this is a practical checklist to start using now.

Client triage list

• Identify all clients with wages, directors' fees or closely held payees
• Flag clients with high staff turnover in 2025–26
• Flag clients that changed payroll software or bookkeepers during the year
• Flag clients with regular allowances, bonuses or commissions
• Flag clients with termination payments, backpay or leave cash-outs

Data review checklist

• Reconcile gross wages in payroll to the general ledger year-to-date
• Reconcile PAYG withholding to IAS/BAS lodged figures
• Review super accruals against fund payments and clearing house records
• Check employee TFNs, addresses and dates of birth are complete
• Review income types and country codes where relevant
• Review allowances, deductions and salary sacrifice coding
• Confirm director wages and shareholder employee payments are correctly reported
• Review terminated employees and final pay processing

Communication checklist

• Send clients an April payroll review request list
• Ask about bonuses, commissions or one-off payments planned before 30 June
• Confirm whether any staff have ceased, gone on leave, or changed employment status
• Remind clients that finalisation is not just a software click — it depends on clean data

A practical example: how a small payroll issue becomes a July problem

Consider a construction business with 14 employees. During the year, it paid site allowances, a tool allowance and several termination payments. The business also moved from one bookkeeping provider to another in November 2025.

In June, the accountant discovers:

• two employees were duplicated in payroll after migration
• tool allowances were coded as ordinary time earnings
• one termination was processed as ordinary wages instead of using the correct tax treatment
• super for one quarter was accrued but not reconciled to actual fund payments

At that point, the firm is already dealing with EOFY accounts, trust work and June BAS preparation. What could have been a tidy April review becomes a July rework project involving amended pay events, employee queries and delayed finalisation.

This is exactly why STP finalisation is such a timely topic in April 2026: the work that prevents year-end stress needs to start before year-end.

How small businesses can prepare now

Small business owners do not need to become payroll experts, but they do need to make sure their records are complete and their adviser has what they need. In April 2026, employers should:

• review employee lists and remove duplicate or inactive records
• check that all pay runs up to March 2026 have been lodged through STP
• confirm super payments are up to date and evidence is retained
• identify any unusual payments expected before 30 June, such as bonuses or director payments
• tell their accountant or bookkeeper about staff exits, redundancies or leave payouts
• avoid making manual payroll adjustments outside the software unless advised

If records are messy, now is the time to clean them up. Waiting until late June usually means more errors, higher accounting fees and more disruption.

Where payroll data and bookkeeping records often disconnect

One recurring issue in Australian businesses is that payroll looks correct inside the payroll file, but the bookkeeping does not match. PAYG withholding accounts do not reconcile to BAS, wage expense accounts contain miscoded journals, or bank transactions have been posted inconsistently.

For accountants doing catch-up work or compliance recovery, fixing STP finalisation often requires tracing the underlying ledger entries, not just reviewing payroll reports.

This is where workflow matters. Tools like Fedix MyLedger can help practices dealing with messy client records by turning bank statements into usable financial data quickly and surfacing transactions that need review. For firms inheriting incomplete books, that can make it easier to reconcile payroll-related cash movements before year-end. Fedix's ATO integration can also help centralise client compliance visibility when practices are juggling BAS, lodgement tracking and payroll-related deadlines at the same time.

As one Sydney CPA put it: "We used to turn away clients without Xero. Now those are some of our best clients" — Holly Wei, Partner, Sydney.

Final thoughts

If you are looking for the most relevant and timely Australian accounting topic in April 2026, STP year-end finalisation is right near the top. It is specific, seasonal, compliance-driven and highly practical. Most importantly, the businesses and firms that act now will have a much easier July than those that wait for EOFY panic to set in.

For accountants and bookkeepers, this is the month to move from reactive payroll cleanup to proactive review. For small business owners, it is the month to make sure your payroll records are complete before the year-end rush.

And if some of your clients have incomplete books, missing bank data or messy historical records, tools like Fedix can help reduce the manual cleanup work that often sits behind payroll and BAS reconciliations. Learn more at fedix.ai.
