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

Why STP finalisation is the most relevant April 2026 accounting topic

In April 2026, one of the most practical and time-sensitive issues for Australian accountants, bookkeepers and employers is Single Touch Payroll (STP) year-end finalisation readiness. While finalisations are not due until 14 July 2026 for most closely held and arm’s-length employees, April is the month when payroll errors become much harder to unwind if they are left untouched.

That is especially true this year because businesses are now operating in an environment of tighter ATO scrutiny across payroll reporting, superannuation timing, contractor classification, and data matching between STP, BAS, super funds and income tax returns. By April, most businesses have already processed nine months of wages for the 2025–26 financial year. If there are coding errors, duplicate pay events, incorrect gross-to-allowance splits, or super payroll mismatches, there is still enough time to correct them before June 30 without creating a July clean-up exercise.

For accounting firms, this is also a highly relevant workflow issue. Clients often assume STP is "done automatically" because payroll is lodged each pay run. In reality, ongoing STP reporting does not remove the need for year-end reconciliation and finalisation checks. April is the ideal point to run those reviews while there is still time to fix payroll categories, employee details and year-to-date balances.

What employers need to remember about STP finalisation for 2025–26

For most employers reporting through STP, the key year-end requirement is to make a finalisation declaration so employees can see their income statement as "Tax ready" in myGov. For many businesses, the standard deadline is 14 July 2026.

That sounds distant in April, but the underlying reconciliation work should start now. Waiting until July often leads to:

• incorrect gross wages or PAYG withholding totals
• allowances reported as salary and wages, or vice versa
• employment termination payments coded incorrectly
• superannuation payroll records not matching actual fund payments
• director or shareholder wages treated inconsistently across payroll and tax records
• duplicate employee profiles after software migrations or payroll resets
• BAS labels not aligning with STP totals for the year

These issues can trigger amended payroll events, employee confusion, and unnecessary ATO attention. For bookkeepers and accountants, they also create avoidable write-offs in July if the client only raises the problem after payroll year-end has closed.

Why April matters more than June for payroll compliance

1. There is still time to correct payroll setup issues

By April, you can identify whether payroll categories have been mapped incorrectly for most of the year. If allowances, leave loading, directors’ fees or salary sacrifice amounts have been coded incorrectly, there may still be time to correct future runs and plan year-end adjustments in a controlled way.

2. Super timing issues become visible

Quarter 3 super guarantee contributions for the period ending 31 March 2026 are generally due by 28 April 2026. That makes April the perfect month to compare payroll super accruals against what has actually been paid to funds. If there is a shortfall, late payment, or employee mismatch, you want to know before June.

3. BAS and STP discrepancies can still be investigated properly

If wages at BAS label W1 or PAYG withholding at label W2 do not broadly reconcile to payroll records and STP submissions, April gives you breathing room to investigate whether the issue relates to timing, coding, amendments, or bookkeeping errors.

4. Employee data can still be cleaned up before finalisation

Incorrect dates of birth, TFNs, addresses, start dates or duplicate employee records are easier to fix before year-end pressure hits. These errors can delay finalisation and create employee tax return issues.

The April 2026 STP health check: what accountants should review now

If you manage payroll for clients or review year-end compliance, April is the right time to run a structured STP health check. Here is a practical review framework.

1. Reconcile payroll year-to-date figures to accounting records

Compare year-to-date payroll reports as at 31 March 2026 or 5 April 2026 against the general ledger. Review:

• gross wages and salaries
• PAYG withholding
• superannuation expense and liability accounts
• allowances
• salary sacrifice
• termination payments
• director fees or shareholder remuneration

Look for unusual suspense balances, manual journals posted to wage accounts, or payroll clearing accounts that have not zeroed out correctly.

2. Check BAS labels against payroll reports

For quarterly or monthly lodgers, compare lodged BAS totals to payroll/STP totals for the same periods. Differences may be valid due to timing, but they should be explainable. Red flags include:

• W1 lower than payroll gross because allowances or bonuses were excluded
• W2 not matching payroll withholding because of manual payment errors
• superannuation expense posted without corresponding payroll entries
• contractor payments accidentally processed through wages

3. Review employee master data

Confirm that active and terminated employees have complete and accurate records, including:

• full legal name
• TFN
• date of birth
• address
• employment basis
• commencement and termination dates
• super fund details

Duplicate employee cards remain a common issue after payroll software changes or hurried onboarding.

4. Test payroll category mapping

Check whether each pay item is mapped correctly for STP Phase 2 reporting. This is particularly important for:

• bonuses and commissions
• overtime
• travel and other allowances
• paid leave categories
• salary sacrifice to super
• reportable fringe benefits where applicable
• lump sum and termination components

Even where payroll software automates reporting, setup errors can flow through the entire year.

5. Compare super accrued to super paid

Do not assume the payroll file tells the full story. Compare the super liability in payroll and the general ledger to actual payments made to the clearing house or fund. This review is especially important in April because the 28 April 2026 due date is close enough to act on.

Common STP issues showing up in small business clients right now

In practice, these are some of the most common issues firms are finding in April payroll reviews:

• Owner wages processed inconsistently — especially in family companies where directors take mixed payments through payroll, drawings and loan accounts
• Allowances not separated correctly — causing inaccurate STP categories and employee income statements
• Terminated staff still appearing as active — often with duplicate year-to-date figures after reactivation
• Super liabilities overstated — because payroll journals were posted but payments were delayed or rejected
• Bookkeeping clean-up journals breaking payroll reconciliation — particularly where non-payroll users post directly to wage or PAYG accounts
• Contractors incorrectly treated as employees or vice versa — creating reporting and withholding confusion

These are not just technical payroll issues. They affect BAS accuracy, income statement finalisation, super compliance, and year-end tax reporting.

A practical April action plan for accountants and bookkeepers

If you want to avoid a July bottleneck, here is a practical workflow to implement in April 2026.

Step 1: Segment clients by payroll risk

Not every client needs the same level of review. Prioritise clients who:

• have changed payroll software during 2025–26
• have high staff turnover
• pay irregular bonuses or director remuneration
• have had bookkeeping catch-up work during the year
• have a history of BAS or super lodgement issues
• operate in industries with award complexity, such as hospitality, construction or healthcare

Step 2: Run a March quarter payroll reconciliation

Use the quarter ending 31 March 2026 as your review point. Reconcile payroll reports to:

• bank payments
• general ledger wage and PAYG accounts
• BAS labels W1 and W2
• super clearing house or fund confirmations

Step 3: Fix data integrity issues before the final quarter closes

Correct employee records, pay item mappings, inactive duplicates and coding issues now. If historic adjustments are needed, document the approach clearly so the June and July payroll process remains controlled.

Step 4: Communicate with clients early

Many clients do not understand the difference between pay-run lodgement and year-end finalisation. Send a short April advisory explaining:

• what STP finalisation is
• why payroll needs a review before 30 June
• what records the client needs to provide
• what deadlines your firm will work to

Step 5: Build finalisation into your EOFY workflow now

Do not leave payroll finalisation as a separate July task. Tie it into your EOFY checklist alongside trust resolutions, super cut-off planning, debtor reviews and year-end reconciliations.

What small business owners should do in April 2026

If you are a business owner managing payroll internally, April is the month to ask your bookkeeper or accountant these five questions:

• Do our STP year-to-date figures match our bookkeeping records?
• Have all super payments been made on time and allocated correctly?
• Are our employee details complete and accurate?
• Are allowances, leave and bonuses being reported correctly?
• Will we be ready to finalise STP by 14 July 2026 without amendments?

If the answer to any of these is uncertain, it is worth addressing now rather than after year-end. Payroll errors are usually cheaper to fix before June than after employees start lodging their tax returns.

Where automation can help without replacing review

For firms dealing with messy books, payroll reviews often get delayed because the underlying transaction data is incomplete or behind. That is where workflow and clean-up tools can help. For example, if a client’s bank data, bookkeeping or BAS history needs to be brought up to date before you can trust payroll reconciliations, tools like Fedix MyLedger can help accelerate the clean-up process by turning bank statements into usable ledger data and supporting faster compliance recovery.

Fedix’s ATO integration can also help firms keep track of client obligations and reduce the admin burden around lodgement visibility while the team focuses on higher-value review work. That matters in April, when payroll, BAS, super and EOFY planning often collide in the same few weeks.

As one Sydney CPA, Sam Malla, put it: “Three days of catch-up work, billed for two hours. Now we’re profitable on those jobs.” For firms inheriting incomplete records, profitability often depends on getting the data in shape early enough to do meaningful compliance reviews before deadlines hit.

Final thoughts: April is the control point for July STP finalisation

In April 2026, the most timely payroll issue is not the finalisation declaration itself. It is whether employers and advisers are doing the reconciliation and data-cleaning work early enough to make finalisation straightforward in July.

For Australian accountants and bookkeepers, this is a practical opportunity to add value: identify payroll reporting gaps, align STP to BAS and super records, and prevent a last-minute year-end scramble. For small business owners, it is a chance to make sure payroll is genuinely compliant rather than simply lodged.

The firms that act in April usually have a smoother June and a far less stressful July. If your client list includes payroll complexity, software migrations, catch-up bookkeeping or owner-managed businesses, now is the time to start the STP health check.
