There are two kinds of bookkeepers in late June. One is calmly working through a checklist they started in May. The other is Barry, who has just discovered that "EOFY" is not, in fact, a type of pasta, and is now hiding in the stationery cupboard whispering that the due date is more of a vibe.
Published: June 2026
This is the checklist. If your bookkeeper has not raised most of these with you yet, forward them this article. Or forward yourself this one.
Everything else on this list depends on the file being reconciled to 30 June: every bank account, credit card, loan and payment platform. Not "the main account". All of them. A file with 300 unreconciled transactions does not have an EOFY problem, it has an every-day problem that EOFY exposes. If that sounds like your file, the war crimes list will feel familiar, and a Free Xero Roast will tell you how deep it goes.
Before finalisation, payroll needs to balance three ways: what the payroll system says was paid, what STP reported to the ATO during the year, and what actually left the bank. Allowances coded correctly, salary sacrifice handled, terminations processed properly. Then the STP finalisation declaration is due by 14 July 2026, at which point your team's income statements turn "tax ready" in myGov and the where-is-my-payment-summary messages stop. Miss it and you become the reason eleven employees cannot lodge their returns.
Quarterly super for April to June is due by 28 July 2026, and it is the last quarterly super payment under the old system. The part your bookkeeper should have flagged weeks ago: employer super contributions are generally only deductible in the year the fund receives them. Paying the June quarter in early-to-mid June, with enough buffer for clearing house processing, is the difference between deducting it this year or next. Whether that timing makes sense for your tax position is your accountant's call. Making sure the question gets asked before 30 June, rather than discovered in September, is the bookkeeper's.
From 1 July 2026, super is payable every payday and must reach employees' funds within 7 business days. The quarterly cycle is gone. Two practical jobs needed doing before now:
The penalty regime for late super also sharpens under the new system, with ATO-assessed charges and daily interest. The era of quietly paying super a few weeks late is over.
An aged receivables review before 30 June, not after. Invoices that are genuinely dead may be claimable as bad debts, but generally only if written off before year end, which is a decision for you and your accountant that cannot be made retroactively. Same energy on the creditor side: supplier statements reconciled, disputed invoices resolved or documented, so the year-end accounts payable figure means something.
If you carry inventory, a stocktake at or near 30 June, with the count actually entered into the file rather than living in a spreadsheet called "stocktake_FINAL_v3". The asset register reviewed: things scrapped, sold or lost during the year removed, so depreciation next year is calculated on assets that exist. Hospitality and ecommerce clients, this is your section, and there is more in the hospitality group guide.
Director loan account movements documented. Owner spending separated from business spending, properly, not via a suspense account the size of a small moon. Hire purchase and loan balances reconciled to lender statements. GST control accounts reconciled to the BAS actually lodged. None of this is glamorous. All of it is the difference between your accountant doing tax work and your accountant doing forensic accounting at tax-work prices.
The Q4 BAS is due 28 July, or 25 August through a registered agent's electronic lodgement program. A bookkeeper who has done items 1 through 7 can draft it in an afternoon and tell you the payment figure weeks in advance. The full deadline breakdown, including what late actually costs, is in the BAS deadline guide.
A hypothetical 18-staff Alexandria ecommerce business, $4M revenue. Their bookkeeper starts the EOFY run in mid May: reconciliations were already current (they always are), payroll balanced in the first week of June, June-quarter super scheduled for 16 June with the deduction question already sitting in the accountant's inbox, stocktake booked for the evening of 30 June, Payday Super configured in the payroll platform and tested on a dummy run. Total drama: none. Total late nights: none. That is not heroism, it is just what current books make possible.
The other version of this story involves a panicked week in late July, an accountant's bill with a "file reconstruction" line on it, and a super deduction that quietly moved to next year. Same business, same numbers, different bookkeeper. If yours is the second kind, the warning signs are catalogued in 13 signs your bookkeeper is Boring Barry, and what a proper one costs is in the 2026 pricing guide.
When is STP finalisation due for 2025-26?
14 July 2026. After finalisation, employees' income statements show as tax ready in myGov.
When does Payday Super start?
1 July 2026. Super must be paid with each pay run and reach the fund within 7 business days of payday. The final quarterly payment, for April to June 2026, is due 28 July 2026.
Do I have to pay June quarter super before 30 June?
No, the legal due date is 28 July. But contributions are generally only deductible when received by the fund, so paying before 30 June with processing buffer is how the deduction lands in this financial year. Whether to do that is a question for your accountant.
What happens to the Small Business Superannuation Clearing House?
It closed to users from 1 July 2026. Businesses that relied on it need payroll-integrated super payments or a commercial clearing house in place before their first July pay run.
What does my accountant need from the bookkeeper at year end?
A fully reconciled file, balanced payroll, reconciled GST and loan accounts, supporting documents attached, and a list of judgement calls flagged rather than buried. Clean handover is most of what separates a cheap accounting bill from an expensive one.
Can I switch bookkeepers right at EOFY?
Yes. It is busier, but a competent bookkeeper takes over files in July constantly, and starting the new financial year with a clean file beats dragging the old mess into it. The steps are in the switching guide.
Is EOFY tax planning the bookkeeper's job?
No. Tax planning is your accountant's or registered tax agent's job. The bookkeeper's job is making sure the file is so current and clean that tax planning is possible before 30 June rather than archaeologically reconstructed after it.
