Single Touch Payroll Finalisation 2025–26: Why April 2026 Is the Right Time for Australian Employers to Fix Payroll Data

Why STP finalisation is suddenly a timely April 2026 accounting topic

In April 2026, many Australian accountants, bookkeepers and payroll teams are shifting their attention to a very specific issue: Single Touch Payroll (STP) year-end finalisation readiness for the 2025–26 financial year. While STP finalisation itself happens after 30 June, April is one of the most practical windows to identify payroll errors early, clean up year-to-date data, and avoid a June rush.

This is especially relevant in 2026 because payroll compliance pressure has continued to increase across superannuation, award interpretation, contractor classification, and ATO data matching. For businesses with messy records, legacy payroll setups, or multiple software systems, waiting until July to review STP data can create expensive corrections, employee confusion, and amended reporting.

If you are an Australian accountant advising employer clients, or a business owner running payroll internally, April is the month to start a structured STP health check.

What STP finalisation means in practice

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 employees can use their income statement as "tax ready" information in myGov.

For closely held payees, different timing concessions may apply, but for many employers the core issue is the same: the year-to-date figures lodged through STP need to be correct before finalisation.

That means April 2026 is a smart point to review:

• gross wages and salary sacrifice coding
• PAYG withholding totals
• superannuation guarantee treatment
• allowance categories
• director and shareholder wages
• termination payments and ETP reporting
• contractor versus employee treatment where payroll practices have changed
• employee master data such as TFNs, dates of birth and addresses

Why this matters more in 2026 than it used to

1. The ATO has more payroll visibility than ever

STP has changed payroll from a once-a-year reporting exercise into a near real-time compliance data stream. The ATO can compare payroll reporting against BAS labels, super fund reporting, prior-year trends and individual tax returns. That makes inconsistencies easier to detect.

For example, if wages reported through STP do not align with BAS W1 and W2 amounts across the year, or if superannuation appears understated relative to ordinary time earnings, employers may face questions well before income tax returns are finalised.

2. Super compliance is under heavier scrutiny

The super guarantee rate for 2025–26 is 12%, following the scheduled increase from 11.5% on 1 July 2025. If payroll systems were not updated correctly at the start of the financial year, underpayments may now be embedded in year-to-date figures.

April gives businesses time to identify and remediate issues before 30 June. Leaving it until finalisation can mean rushed recalculations, Superannuation Guarantee Charge exposure, and employee relations problems.

3. Award interpretation and payroll coding errors are compounding

Across hospitality, healthcare, construction, retail and professional services, many employers are still dealing with payroll complexity around allowances, overtime, leave loading, and salary sacrifice arrangements. A small setup error in July 2025 can become an 11-month reconciliation problem by May 2026.

That is why April is a highly relevant and timely month for a payroll data review rather than just another bookkeeping month.

The most common STP issues to review in April 2026

Mismatch between payroll and BAS

One of the most common year-end problems is that total wages and PAYG withholding reported through payroll do not reconcile to lodged BAS figures. Causes include manual journals, post-BAS payroll adjustments, software migration issues, and incorrect account mapping.

Action step: Reconcile year-to-date STP gross and withholding totals to BAS labels W1 and W2 for the first three quarters now, then maintain the reconciliation monthly through to June.

Super calculated on the wrong earnings base

With the 12% SG rate now applying for 2025–26, employers should review whether payroll has correctly applied super to ordinary time earnings and excluded amounts that are genuinely outside the SG base.

Action step: Run exception reports for employees with unusually low SG percentages relative to gross ordinary earnings.

Allowance categories incorrectly reported

STP Phase 2 reporting requires more detailed income type and allowance categorisation. Errors here can affect employee tax outcomes and create confusion at tax time.

Action step: Review travel allowances, tool allowances, car allowances and other separately identified payroll items to confirm they are mapped to the right STP category.

Closely held payees and director payroll not reviewed

Many SMEs still have directors or related parties paid irregularly, through journals, or outside standard payroll cycles. These arrangements often become a year-end cleanup exercise.

Action step: Confirm whether all director and shareholder remuneration for 2025–26 is being processed consistently and reported correctly through STP.

Terminations and ETPs handled incorrectly

Redundancies, resignations and settlements often create coding issues, especially where unused leave, tax-free components or employment termination payments are involved.

Action step: Review all terminations processed since 1 July 2025 and confirm tax treatment and STP labels are correct.

An April 2026 STP readiness checklist for accountants and bookkeepers

If you manage payroll for clients, this is a practical checklist to work through now.

Payroll data integrity

• Confirm employee legal names, TFNs, date of birth and addresses are complete
• Review duplicate employee cards or inactive records still affecting reports
• Check commencement and termination dates are accurate
• Verify payroll categories are mapped correctly for STP reporting

Reconciliation checks

• Reconcile payroll year-to-date gross wages to profit and loss wages accounts
• Reconcile STP totals to BAS W1 and W2 for each lodged period
• Review PAYG withholding clearing accounts for unexplained balances
• Check super payable balances against payroll reports and clearing house records

Superannuation checks

• Confirm the 12% SG rate has applied from 1 July 2025
• Check for employees near the maximum contribution base where relevant
• Review salary sacrifice arrangements for correct payroll treatment
• Identify any missed or late super payments before year end

Employee payment classification

• Review allowances, bonuses and commissions
• Confirm leave loading, overtime and paid leave categories are correct
• Check termination payments and ETP coding
• Review contractor arrangements that may actually be employment for payroll purposes

Example: how an April review can prevent a July payroll mess

Consider a 22-staff trade business that changed payroll officers in August 2025. The new officer updated pay rates but missed the SG increase to 12% in one earnings category. At the same time, vehicle allowances were coded as ordinary earnings rather than separately reported allowances.

If this is only discovered in July 2026, the business may need to:

• recalculate super for multiple quarters
• consider SGC implications for any shortfalls
• amend payroll records
• adjust STP year-to-date figures
• answer employee questions once income statements change

If it is found in April 2026, there is still time to quantify the issue, process corrections in an orderly way, fund any shortfall, and document the remediation before finalisation season begins.

What accountants should be telling clients right now

For many clients, STP finalisation still feels like a July task. But in practice, April is when advisers can add the most value. The message to clients should be simple: do not wait for EOFY to discover payroll errors that have been accumulating since last July.

Good client advice in April 2026 includes:

• scheduling a payroll compliance review before the end of April
• identifying software setup issues before the final quarter is processed
• checking that super calculations and payment workflows are operating correctly
• reviewing any manual payroll workarounds used during the year
• planning corrections early, especially for director wages and closely held payees

This is also a good time to coordinate payroll review with BAS preparation, because BAS-to-payroll reconciliation often exposes the same underlying data quality issues.

Where workflow and messy records become the real problem

In smaller businesses, payroll errors are often not caused by tax law misunderstandings alone. They are caused by fragmented records: emailed payslip instructions, handwritten reimbursement notes, bank transactions posted after the fact, and missing supporting documents.

That is where accounting workflow matters. If a practice is cleaning up multiple clients with incomplete records, tools that speed up transaction reconstruction and working paper preparation can reduce the time spent getting to a reliable payroll and BAS position.

For firms dealing with catch-up bookkeeping or incomplete source documents, Fedix MyLedger can help reconstruct the ledger from bank statements, PDFs and scans, which is useful when payroll clearing, wage payments or super transactions need to be traced quickly. Its ATO integration can also help practices keep client obligations and lodgement visibility in one place while working through payroll-related compliance cleanup.

Used well, that kind of workflow support does not replace payroll judgment, but it can make April reviews more practical when the records are messy.

Questions to ask before 30 April 2026

Here are five questions every employer or adviser should be asking this month:

1. Do STP year-to-date figures reconcile to lodged BAS figures for all periods so far?
2. Has the 12% super guarantee rate been applied correctly from 1 July 2025?
3. Are allowances, salary sacrifice and terminations coded correctly under current STP reporting categories?
4. Have all director, shareholder and closely held payee amounts been dealt with consistently?
5. Is there enough time to correct any payroll issues before June rather than after finalisation deadlines start?

The bottom line

If you are looking for the most relevant and timely Australian accounting topic in April 2026, STP finalisation readiness deserves to be near the top of the list. It is current, deadline-driven, and highly practical for accountants, bookkeepers and employers alike.

The businesses that treat April as a payroll review month, rather than waiting for July, will usually have a smoother year-end, fewer amendments, and less compliance risk. For firms handling messy books, catch-up payroll or fragmented records, starting now can make the difference between a controlled cleanup and a last-minute scramble.

As one Sydney CPA put it about cleanup work: "Three days of catch-up work, billed for two hours. Now we're profitable on those jobs." That same principle applies to payroll compliance. The earlier the data is repaired, the more manageable the year-end becomes.
