The final quarter of the financial year is the most critical period for every Australian business. Before June 30, business owners, directors, and CFOs must assess every deduction opportunity, finalise all deductible transactions, and verify the accuracy of their financial records. Tax time isn’t simply about compliance, it is the most strategic window to reduce your assessable income and improve your after-tax cash flow position.
The Australian Taxation Office (ATO) provides a range of deductions for operational expenses, asset purchases, prepayments, superannuation, and business development costs. However, many of these deductions are strictly governed by timing rules. Missing a cut-off by a single day could mean deferring a deduction for 12 months or more.
At Blackwattle Tax, we specialise in helping middle-market businesses implement smarter Tax Compliance strategies. Our Chartered Accountants combine top-tier technical knowledge with industry insights to help you capture all allowable deductions and remain fully ATO-compliant.
This guide outlines the most powerful EOFY 2025 deduction tips structured by timing, expense type, and industry relevance. We also explain how our Virtual CFO Services, Bookkeeping reviews, and Strategic Tax Advisory help clients prepare for June 30 with precision.
Timing is everything in tax. The most common cause of missed deductions is delayed documentation or incorrect recognition of expenditure. To ensure every dollar is captured in FY 2024–25, now is the time to act.
Prepaying Expenses for Immediate Deduction
One of the most overlooked deduction strategies before EOFY is the prepayment of expenses. Eligible small businesses those with aggregated turnover under $50 million—can claim an immediate deduction for prepaid expenses that satisfy the 12-month rule.
According to the ATO, prepaid expenditure is deductible in full if:
- The service period is 12 months or less, and
- The service period ends before the end of the next financial year (i.e. before 30 June 2026 for FY 2025 claims)
Common deductible prepayments include:
- Rent or lease payments
- Business insurance premiums
- Software or platform subscriptions
- Memberships or professional association dues
- Loan interest on eligible business borrowings
At Blackwattle Tax, we routinely identify prepayment opportunities during our Strategic Tax Advisory sessions. Clients across retail, hospitality, and health sectors benefit from proactive cash-based deductions structured in the final two months of the financial year.
For example, a business with a June 1 lease renewal may prepay 12 months’ rent and deduct the full amount in FY 2024–25. Likewise, software platforms billed annually in May or June may be prepaid to optimize taxable income.
We recommend reviewing your Chart of Accounts and supplier billing schedules no later than June 10. Our Bookkeeping and Payroll Compliance team ensures these transactions are correctly classified and supported with tax invoices.
To learn whether your business qualifies for full prepayment deductions under simplified depreciation rules, consult our Tax Advisory team before committing funds.
Write-Offs for Bad Debts & Obsolete Inventory
Writing off irrecoverable debts and obsolete stock can significantly reduce your year-end taxable income if done before June 30. These deductions are valid only where supporting evidence and accounting treatment meet ATO requirements.
Bad Debts
To claim a deduction for a bad debt:
- The amount must have been previously included in assessable income
- The debt must be deemed genuinely unrecoverable
- The business must write off the debt in its accounts before June 30
We recommend a full aged receivables review in early June. Our Bookkeeping and Virtual CFO Services teams assist clients in documenting follow-up attempts, litigation outcomes, or customer insolvency confirmations that support the write-off.
Obsolete or Unsaleable Inventory
Under tax law, businesses must record trading stock at cost, market selling value, or replacement cost whichever is lowest. If stock is damaged, expired, or unsaleable, its value can be written down to reflect market value.
This applies especially to:
- Perishable goods (F&B industry)
- Fashion and season-based inventory (retail/ecommerce)
- Redundant spare parts or discontinued products (transport/manufacturing)
We support retail and logistics clients with end-of-year stock takes and valuation adjustments under our tailored industry-specific advisory model.
Important: The deduction applies only if the value is correctly reflected in closing stock figures. Our Chartered Accountants ensure tax adjustments are reflected in both general ledger entries and financial statements.
If your business carries trade receivables or physical stock, book a Blackwattle-led EOFY ledger review to identify deductible write-offs before June 30.
Deducting Business Assets Using Instant Asset Write-Off (IAWO)
Capital purchases can deliver valuable EOFY deductions, but only if timing, usage, and eligibility are aligned. The Instant Asset Write-Off (IAWO) allows eligible businesses to immediately deduct the full cost of qualifying assets.
For FY 2024–25:
Eligibility: Businesses with annual turnover under $10 million
Threshold: Up to $20,000 per asset, provided the asset is:
First used or installed ready for use by 30 June 2025
Acquired for taxable business purposes
From 1 July 2025, the threshold will drop sharply to just $1,000 per item, significantly limiting the upfront deduction benefit.
Example: A medical practice that purchases diagnostic equipment in May 2025 can claim the full deduction in FY 2024–25 if the asset is installed and operational before EOFY.
Our Virtual CFO and Tax Advisory teams help businesses plan capital acquisitions with tax timing in mind. We verify eligibility, review supplier invoices, and ensure the asset meets “ready for use” tests under ATO guidelines.
Employee-Related Deductions & EOFY Actions
Employee-related expenses offer substantial deduction opportunities provided actions are completed before June 30 and recorded in the correct financial year.
Superannuation Guarantee Contributions
To be deductible in FY 2024–25, SG contributions must:
- Be received by the super fund by June 30
- Be cleared through your clearing house (often takes 3–5 days)
Late super payments are not deductible until the following year. Our Bookkeeping team sets up SuperStream-compliant workflows to ensure compliance and deductibility.
Staff Bonuses and Incentive Payments
Bonuses and commissions are deductible if:
- The business is definitively committed to the expense (board resolution)
- The payment obligation exists by June 30, even if paid in July
Blackwattle prepares the necessary board minutes and accrual entries for performance-based remuneration to be deductible in FY 2024–25.
Training, FBT, and Other Staff Benefits
Work-related training, upskilling programs, or external certifications paid before EOFY are deductible. FBT-related items (vehicles, parking, meals) must be substantiated if deducted, and reported through your year-end STP or employee payment summaries.
We support businesses with Fringe Benefits Tax reconciliation and deduction substantiation under our Tax Compliance Services. For larger employers, we integrate payroll reporting and FBT analytics through our Virtual CFO Services.
Proper planning of bonuses, super, and benefits before EOFY not only reduces tax it also strengthens workforce engagement and retention.
Deductions for Business Growth & Development
EOFY isn’t just for operational costs, it’s also the time to claim deductions for strategic development and international expansion.
Export Market Development Grant (EMDG)
Businesses investing in international marketing, website translation, SEO, or overseas travel may deduct these costs and claim matched funding under the EMDG program.
Eligible expenses include:
- International advertising and digital promotion
- Consultant and translator fees
- Overseas market research or travel
Blackwattle’s EMDG Advisory Services ensure your activities are deductible and grant-aligned. We structure expenses to comply with both tax and Austrade rules.
Business Restructuring and Advisory Fees
Legal, accounting, and consulting fees related to:
- Business structure changes
- Capital raising or investment planning
- Regulatory compliance or risk management
…are deductible in the year incurred, provided the service is for business use.
We guide clients through strategic restructuring under our Tax Advisory and CFO Services, ensuring all deductible advisory costs are correctly documented.
Software and Technology Upgrades
Cloud-based tools, cybersecurity upgrades, and workflow automation platforms can be either expensed (if under IAWO) or depreciated. Either way, acquiring these before June 30 delivers long-term performance and short-term tax benefits.
Common EOFY Deduction Mistakes & How to Avoid Them
ATO audits frequently target small and mid-market businesses for errors in deduction claims. The most common risks include:
- Overstated business-use percentage: Deducting 100% of mobile phone or vehicle costs without logbooks or usage data
- Misclassification: Treating capital improvements as repairs or vice versa
- Non-substantiated advisory or contractor payments: Missing contracts, invoices, or payment proofs
Blackwattle Tax prevents these risks by delivering deduction strategies backed by:
- Internal audit trails
- Valid GST-compliant tax invoices
- Director resolutions and advisory engagement letters
We also review ledger entries through our Bookkeeping and CFO Services to ensure treatment aligns with ATO guidance.
If you’ve claimed large one-off deductions this year such as advisory fees, asset purchases, or international expansion expenses our Chartered Accountants can run a final EOFY deduction health check.
