As the end of the financial year approaches, now is the time for Australian business owners to put proactive accounting and tax planning strategies into action. This article covers essential EOFY tactics for 2025 — from super contributions and asset write-offs to stocktake and structure reviews. With the right approach, business owners can minimise their tax bill, improve cash flow, and start the new financial year on the front foot. 

Why EOFY Accounting and Tax Planning Matters in 2025?

The last quarter of the financial year is when smart business owners get proactive. It’s the time to step back and ask: How did we perform this year? What can we do now to reduce tax, improve our structure, and set the stage for a better 2026? 

Following the 2025–26 Federal Budget, many are wondering: “Is there anything in this for my business?” The truth is, with the right guidance, there often is. 

EOFY is the ideal time to combine strategic accounting and tax planning to: 

  • Project your tax liability 
  • Implement deductions while there’s still time 
  • Review business systems and software 
  • Revisit your business structure 
  • Manage your profit and cash position effectively

“Most of the time, our clients don’t realise the full benefits of what our accounting and tax planning achieves for them. It’s not just about reducing their tax bill for the current year — it’s the compound impact over many years that truly makes a difference. Through strategic savings, smart investment decisions, and future planning, we help set them up for long-term success. It’s incredibly rewarding to see clients genuinely happy with their tax outcomes.”  — Ross Girgenti, Director at Cosca 

Key EOFY Accounting and Tax Planning Strategies for Business Owners 

1. Can your business claim the $20,000 Instant Asset Write-Off? 

If your turnover is under $10 million, you can immediately deduct the cost of assets under $20,000 — as long as they’re installed and ready for use by 30 June 2025. 

This is a great EOFY move for those upgrading tools, vehicles or tech — particularly if your accounting software or systems are due for an upgrade. 

2. Are you maximising superannuation contributions? 

Making concessional super contributions is a proven strategy to reduce taxable income. These include: 

  • Employer SG contributions (11.5% to 30th June and then 12% from 1 July 2025) 
  • Salary sacrifice arrangements 
  • Personal deductible contributions 

EOFY is the time to check your contribution cap and consider catch-up contributions using unused caps from previous years. 

3. Have you reviewed your stocktake? 

If your business holds inventory, a detailed stocktake before 30 June can unlock deductions for: 

  • Obsolete or slow-moving stock 
  • Write-downs due to damage or misvaluation 

This isn’t just about tax — it’s good accounting hygiene and supports better decision-making into FY26. 

4. Are there bad debts you can write off? 

Writing off unrecoverable debts before EOFY provides a legitimate deduction — but they must be documented and written off by 30 June. If you haven’t reviewed your receivables recently, now is the time. 

5. Is your business structure still right for you? 

The right structure can make or break your tax and accounting position. EOFY is an ideal time to assess: 

  • Exposure to Division 7A if operating via a company 
  • Suitability of trust, partnership or sole trader structures 
  • Succession and asset protection considerations 

6. Are you across changes to tax and accounting laws? 

EOFY 2025 comes with changes you should be planning for: 

  • Stage 3 personal income tax cuts 
  • Superannuation guarantee changes 
  • Energy-efficiency incentive for small businesses 

A good accountant won’t just help you comply — they’ll help you capitalise. 

EOFY Planning Checklist for Business Owners 

  • Forecast tax position and assess profitability 
  • Review super contributions for all key stakeholders 
  • Complete EOFY stocktake and write off unsellable inventory 
  • Review and write off bad debts 
  • Evaluate business structure and Division 7A risks 
  • Consider prepayments of deductible expenses 
  • Review accounting systems — are you due for an upgrade? 

Frequently Asked Questions 

When is the EOFY deadline for tax and accounting actions? 

All deductions and adjustments must be completed by 30 June 2025 to apply to this financial year. 

Is the $20,000 asset write-off still available? 

Yes, for eligible businesses under $10 million turnover — but the asset must be installed and ready by 30 June. 

What’s the benefit of super contributions before EOFY? 

They reduce taxable income and build retirement wealth. They’re a smart EOFY move for directors and employees alike. 

What is Division 7A and why does it matter? 

It relates to loans made from private companies to shareholders or associates. Improperly structured, they can lead to unexpected tax bills.
