May 2026 Tax Time Prep: What Australian Accountants Need to Do Now for the 2025–26 Return Season

May is always a pivotal month in Australian accounting, but May 2026 is especially important because it is the last practical window for firms to get ahead of tax time work before June lodgment pressure hits. For many practices, this is when the real compliance backlog starts: missing receipts, unreconciled bank feeds, incomplete fixed asset records, Division 7A issues, and clients who still have not responded to document requests.

If you are searching for a relevant, timely topic in Australian accounting right now, this is it: how to prepare for the 2025–26 tax return season before EOFY. The firms that act in May tend to move faster in June, reduce review time, and avoid the scramble that comes with last-minute lodgments.

This article covers the most practical steps Australian accountants, bookkeepers, and small business owners should take in May 2026 to prepare for tax time, including what to review, what to chase from clients, and where the biggest compliance risks usually sit.

Why May 2026 matters so much for Australian accounting

May sits in the narrow gap between day-to-day BAS work and the end-of-financial-year rush. That makes it the ideal month to clean up the records that will feed into June tax returns, financial statements, trust distributions, and year-end planning.

For practices, May is also when workflow discipline matters most. If client data is not organised now, the work simply gets pushed into June and July, when the pressure increases and turnaround times blow out.

In practical terms, the most relevant and timely priority in May 2026 is not a new law or a one-off ruling. It is making sure the 2025–26 year-end file is ready before 30 June 2026.

The main compliance areas to review before 30 June 2026

1. Bank reconciliations and unreconciled transactions

Bank reconciliation is still the foundation of every clean tax return. If bank accounts are not current, everything else becomes slower and less reliable: GST coding, expense claims, loan balances, and cash flow analysis.

In May, accountants should identify:

• unreconciled bank transactions older than 30 days
• duplicate entries
• missing bank feeds
• uncoded suspense items
• business/personal mixed transactions

For clients with messy records or bank statements only, this is where a bank-statement-first workflow can save significant time. Tools like Fedix’s MyLedger 1-Click Bank Reconciliation are built for exactly this kind of catch-up work, turning bank statements in PDF, scan, or screenshot form into reconciled financial data in minutes.

2. BAS, GST and adjustment checks

May is a good month to run a GST health check before the final BAS periods of the year are lodged. That means reviewing whether GST has been applied correctly, whether input tax credits have been missed, and whether any private use or adjustments need to be accounted for.

Common issues include:

• GST claimed on private expenses
• business purchases coded to non-deductible accounts
• incorrect treatment of entertainment or motor vehicle expenses
• missing tax invoices for claims over $82.50 including GST
• cash and accrual mismatches

Small businesses should also ensure their BAS lodgment cycle is current and that all source documents are retained. If a client has been behind for months, the clean-up should start now, not after 30 June.

3. Superannuation and payroll records

Even though many employers focus on super and payroll only when deadlines loom, May is the right time to review whether payroll records are complete for the year. This includes super contributions, leave balances, payroll journals, and any adjustments that may affect year-end reporting.

Check for:

• employees missing TFNs or super fund details
• payroll journals not matching bank payments
• bonus or commission payments coded incorrectly
• contractors who may need review under payroll or PSI rules

For accountants, this is also a chance to identify whether payroll data will support clean STP finalisation and year-end reconciliation.

4. Fixed assets and depreciation records

Asset registers are one of the most common year-end pain points. If assets were bought throughout the year and not tracked properly, tax depreciation schedules can become time-consuming very quickly.

Review:

• purchases over $300
• business-use percentage
• asset disposal records
• trade-ins and scrap write-offs
• repairs versus capital improvements

Remember that the $20,000 instant asset write-off was available for eligible small businesses in the 2024–25 year, but eligibility and timing matter. By May 2026, clients should be checking whether any planned purchases were actually installed and ready for use within the relevant income year, rather than assuming they qualify automatically.

5. Division 7A and loan account clean-up

May is also the right time to review private company loan accounts and Division 7A exposure. This is one of the easiest areas for avoidable compliance problems to build up during the year.

Practices should check:

• drawings accounts with no formal loan agreement
• minimum yearly repayments
• unpaid trust distributions
• director-related expenses paid by the company
• loan balances that may need reclassification before 30 June

If there are historical transactions to work through, AI working papers can reduce the manual load. Fedix includes AI Working Papers that can help generate Division 7A loan calculations and interest support faster, which is useful when you are cleaning up multiple entities at once.

A practical May 2026 checklist for accountants and bookkeepers

If you want a simple workflow for May, use this checklist.

Client data and source documents

• Request missing bank statements for the full 2025–26 year to date
• Chase outstanding receipts, invoices, and loan documents
• Confirm payroll reports are complete through May
• Ask clients to flag any private expenses paid from business accounts

Reconciliation and coding

• Reconcile all bank and loan accounts up to the latest available statement
• Clear suspense and uncoded items
• Review GST coding on high-value transactions
• Check for duplicated supplier bills and duplicate receipt claims

Year-end risk review

• Review director loan accounts and trust distributions
• Identify assets purchased or sold during the year
• Check payroll journals against super payments
• Look for missing tax invoices and non-deductible expenses

Workflow and lodgment readiness

• Prioritise clients with overdue records or messy books
• Set internal deadlines for June cleanup work
• Prepare a list of open questions for each client
• Segment jobs by complexity so simple returns do not get delayed by problem files

What small business owners should do in May 2026

Small business owners often think tax time starts in July, but the best outcomes come from preparation in May. If you run a small business, this is the month to get your records in order before your accountant starts asking for them.

Here is what to do now:

• download all bank statements for the year to date
• collect receipts for equipment, motor vehicle, travel, and home office claims
• check that employee super has been paid and recorded correctly
• separate personal and business spending where possible
• confirm any loans from the company or to the company
• review unpaid invoices and outstanding bills

Doing this in May reduces the chance of missed deductions, late adjustments, and rushed decisions in June.

Common mistakes that create tax time delays

Australian practices see the same issues every year, and May is the best time to catch them early.

• Waiting for June – the biggest mistake is assuming there will be time later.
• Incomplete bank data – a missing month of statements can hold up an entire file.
• Poor receipt capture – if documents are not linked to transactions, review time increases sharply.
• Unreviewed private use – mixed-use expenses often create GST and deduction problems.
• Ignoring historical clean-up – old unreconciled balances usually get worse, not better.

For firms dealing with shoebox clients or catch-up bookkeeping, bulk document handling can make a major difference. Fedix’s SmartDoc feature allows bulk receipt upload with AI auto-matching to transactions, which can help reduce the manual effort involved in year-end clean-up.

How to prioritise clients in May 2026

Not every client needs the same level of attention. A sensible prioritisation model for May is:

1. High-risk, high-value clients – entities with trust structures, company loans, payroll, or complex GST.
2. Catch-up clients – clients with incomplete books, missing statements, or multiple years behind.
3. Standard compliance clients – clean files that mainly need final review and lodgment.
4. Low-complexity clients – simple sole traders or micro businesses with few transactions.

This approach helps practices protect capacity and avoid having simple work delayed by messy files.

How Fedix can help with May 2026 year-end prep

For firms that are already deep in cleanup mode, the biggest gains usually come from faster reconciliation and better document matching. That is where Fedix can be useful.

MyLedger is designed for accountants who inherit messy books, not businesses doing their own bookkeeping. It can turn bank statements into reconciled financial statements quickly, support historical cleanup, and generate working papers that reduce the manual load around Division 7A, BAS checks, and year-end prep.

As Grace Chan, CPA, Sydney, put it: “Cut BAS prep time from 2 days to 1 hour.” That kind of time saving matters most in May, when every hour saved now becomes capacity in June.

Final thoughts

The most relevant and timely topic in Australian accounting for May 2026 is simple: getting 2025–26 year-end records ready before the EOFY rush. This is the month to clean up bank reconciliations, review GST and BAS issues, check payroll and super records, and identify Division 7A or asset problems before they become June bottlenecks.

For accountants and bookkeepers, the firms that win at tax time are the ones that start now. For small business owners, the best move is to get your records into shape before your accountant has to chase them.
