EOFY 2026 Reconciliation Checklist for Australian Businesses: A Bookkeeper's Complete Guide

The end of the financial year is the most demanding period in the bookkeeping calendar. For Australian businesses, getting EOFY reconciliation right is not just about ticking compliance boxes — it directly affects the accuracy of your tax return, the reliability of your financial statements, and your ability to start the new financial year on solid footing. A skilled bookkeeper is your most valuable asset during this period.

Understanding EOFY Reconciliation in Australia

End of financial year reconciliation is the process of verifying that all financial records are accurate, complete, and consistent as at 30 June. It involves matching your internal records against external statements, ensuring all transactions are correctly coded, and preparing the data your accountant or tax agent needs to lodge your tax return.

In Australia, the EOFY process has become significantly more complex in recent years. The introduction of Single Touch Payroll (STP) Phase 2, the transition to Payday Super from 1 July 2026, and the ATO's expanded data-matching capabilities mean that errors in your books are more likely to be detected — and more costly to correct.

Why EOFY Reconciliation Matters More Than Ever in 2026

The ATO's data-matching program now cross-references information from banks, share registries, payment platforms, and employers. Discrepancies between your lodged returns and third-party data can trigger audits, amended assessments, and penalties. A thorough EOFY reconciliation is your first line of defence.

The closure of the ATO's Small Business Superannuation Clearing House (SBSCH) on 1 July 2026 and the commencement of Payday Super also mean that the 2025–26 EOFY is a critical transition point for payroll and superannuation compliance.

The EOFY Reconciliation Checklist: Key Areas

A comprehensive EOFY reconciliation covers several interconnected areas. Here is what a qualified bookkeeper will work through on your behalf.

Bank and Credit Card Reconciliation

• Reconcile all bank accounts — Every bank account, credit card, and loan account must be reconciled against the final statement for June 2026. Unreconciled items must be investigated and resolved.
• Clear outstanding items — Unpresented cheques, deposits in transit, and bank errors must be identified and either cleared or carried forward with proper documentation.
• Review petty cash — Petty cash balances should be counted and reconciled against the ledger.

Accounts Receivable and Payable

• Review aged receivables — Identify overdue invoices and determine whether any debts are genuinely unrecoverable. Bad debts written off before 30 June may be deductible for the 2025–26 year.
• Reconcile accounts payable — Ensure all supplier invoices received before 30 June are entered into the system, even if payment is made in July. Accrued expenses must be recorded in the correct period.
• Check for duplicate entries — EOFY is a common time for duplicate invoices or payments to surface. A systematic review prevents overpayment and incorrect deductions.

GST and BAS Reconciliation

• Reconcile GST collected and paid — The GST balance in your accounting software should match the total GST reported across all BAS lodgements for the year. Any discrepancy must be investigated before your annual tax return is prepared.
• Review GST coding — Check for common errors such as private expenses coded as business, missing GST on cash purchases, or incorrect treatment of GST-free and input-taxed supplies.
• Confirm BAS lodgements are up to date — All quarterly or monthly BAS lodgements for 2025–26 must be lodged and any outstanding amounts paid before your accountant can finalise your tax return.

Payroll and Superannuation

• Finalise STP by 14 July 2026 — Employers must submit their STP finalisation declaration by 14 July 2026 to make employee income statements "tax-ready" in myGov. Late finalisation can delay employee tax returns and attract ATO scrutiny.
• Reconcile superannuation — The superannuation guarantee rate for 2025–26 is 12%. All contributions must be received by the employee's super fund before 30 June to be deductible in the 2025–26 year. Allow at least two weeks for clearing house processing times.
• Prepare for Payday Super — From 1 July 2026, employers must pay superannuation at the same time as wages, with contributions reaching the fund within seven business days of payday. The SBSCH closes on this date. Businesses must transition to an alternative SuperStream-compliant clearing house before 1 July.
• Review leave liabilities — Annual leave, personal leave, and long service leave balances must be reconciled and correctly reflected as liabilities on the balance sheet.

Inventory and Fixed Assets

• Conduct a stocktake — A physical inventory count as at 30 June is required for businesses that hold trading stock. Obsolete or damaged stock should be written down to net realisable value before year-end.
• Review the fixed asset register — Confirm that all assets purchased during the year are recorded, depreciation has been calculated correctly, and any disposed assets have been removed from the register.
• Instant asset write-off — The $20,000 instant asset write-off threshold applies to eligible assets first used or installed ready for use by 30 June 2026. Assets must be correctly coded and the write-off claimed in the 2025–26 year.

Common Mistakes to Avoid

Even experienced business owners make EOFY reconciliation errors that create problems down the track. Here are the most common pitfalls.

• Missing the STP finalisation deadline — Failing to finalise STP by 14 July 2026 means employee income statements remain "not tax-ready," preventing employees from lodging their tax returns and potentially triggering ATO follow-up.
• Superannuation paid after 30 June — Contributions that are not received by the fund before 30 June are not deductible in the 2025–26 year. Many businesses underestimate clearing house processing times and miss the effective deadline.
• Incorrect period allocation — Expenses incurred before 30 June but paid in July must still be accrued in the 2025–26 accounts. Failing to accrue these expenses understates your deductions.
• Unreconciled loan accounts — Director loan accounts and intercompany loans must be reconciled and reviewed for Division 7A compliance before year-end. Unresolved balances can create unexpected tax liabilities.
• Ignoring the SBSCH closure — Businesses that have not transitioned away from the SBSCH before 1 July 2026 will be unable to make superannuation payments through that channel from that date, risking non-compliance with Payday Super obligations.

Australian Regulatory Context

EOFY reconciliation obligations in Australia are governed by a combination of tax law, superannuation legislation, and ATO administrative requirements.

ATO Record-Keeping Requirements: Under the Income Tax Assessment Act 1997, businesses must retain financial records for five years. The ATO's digital record-keeping guidance encourages the use of cloud-based accounting software that maintains an audit trail of all transactions.

Single Touch Payroll: STP Phase 2 requires employers to report detailed payroll information to the ATO each pay run. The EOFY finalisation process confirms that all payroll data reported during the year is accurate and complete.

Superannuation Guarantee: The Superannuation Guarantee (Administration) Act 1992 requires employers to pay the superannuation guarantee on time and in full. From 1 July 2026, the Payday Super regime imposes a seven-business-day payment window, with the Superannuation Guarantee Charge (SGC) applying to late or underpaid contributions.

BAS Agent Registration: Bookkeepers who prepare and lodge BAS on behalf of clients must be registered as BAS agents with the Tax Practitioners Board (TPB). The TPB's Code of Professional Conduct requires BAS agents to act with integrity, maintain competence, and keep client information confidential.

GST Legislation: The A New Tax System (Goods and Services Tax) Act 1999 governs GST obligations. Businesses with a GST turnover of $75,000 or more must be registered for GST and lodge BAS on time.

Questions to Ask Your Bookkeeper: A Practical Checklist

If you are engaging a bookkeeper to manage your EOFY reconciliation, these questions will help you assess their capability and ensure nothing is missed.

• Are you a registered BAS agent? Only registered BAS agents can legally prepare and lodge BAS on your behalf.
• What is your process for reconciling bank accounts and GST? A systematic, documented approach is essential for accuracy.
• How will you handle the STP finalisation? What is your timeline, and how will you communicate with employees about their income statements?
• Have you reviewed our superannuation payments to ensure they will be received by the fund before 30 June? What clearing house do you use, and what are the processing times?
• Are we set up for Payday Super from 1 July 2026? Have we transitioned away from the SBSCH?
• What software do you use, and how does it integrate with our accounting system? Compatibility between payroll, accounting, and clearing house software is critical for EOFY efficiency.
• What records will you provide to our accountant or tax agent? A well-prepared EOFY reconciliation package significantly reduces the time and cost of tax return preparation.
