Smart EOFY tax planning can legally reduce your tax bill, protect your cash flow, and position your business for a stronger start to the new financial year.

At AEFS, a trusted Sydney accounting firm working with SMEs across the CBD, North Shore, Parramatta, Surry Hills, North Ryde, and Western Sydney, we help business owners maximise every legitimate small business tax deduction before the deadline. We have seen first-hand how a structured EOFY approach transforms a business’s financial position.

This is your complete, practical 2026 EOFY tax planning guide.

Why EOFY Tax Planning Is Critical for Sydney SMEs Right Now

The ATO has significantly intensified its compliance focus on small businesses in 2025-26. Their current priority areas for SMEs include omitted or undeclared income (particularly in construction, hospitality, and professional services), incorrect deduction claims, GST non-compliance, mixing business and personal expenses, and poor digital record-keeping.

The message is clear: the ATO is watching more closely than ever. The opportunity is equally clear — if you are compliant and proactive, there are significant, entirely legal tax savings available to you before 30 June.

1. Secure the $20,000 Instant Asset Write-Off Before It Expires

This is the single biggest tax concession available to eligible Sydney small businesses right now.

What Is the $20,000 Instant Asset Write-Off?

Eligible small businesses can immediately deduct the full business-use portion of any depreciating asset costing less than $20,000 (instead of depreciating over years). The asset must be first used or installed ready for use by 30 June 2026.

Who Is Eligible?

• Aggregated annual turnover under $10 million
• You must use the ATO’s simplified depreciation rules
• New or second-hand assets both qualify

Popular Assets We See Sydney Clients Claiming

Laptops, POS systems, office fit-outs, vehicles under $20k, tools, machinery, and security systems. There is no limit on the number of eligible assets.

Assets $20,000+ go into the small business pool (15% first year, 30% thereafter). If the pool balance falls below $20,000 at year-end, you can write off the entire remainder.

2 Boost Your Superannuation Contributions Before 30 June

Concessional super contributions are taxed at just 15% inside the fund (versus your marginal rate of up to 47%).

2025-26 Concessional Cap: $30,000 per person (includes SG at 11.5%). If your total super balance is under $500,000, you may carry forward unused caps from the past five years.

Key Timing Rules

• Personal deductible contributions: Lodge a Notice of Intent before lodging your tax return or 30 June 2026.
• Employee SG: Must be received by the fund before 30 June 2026.

Always confirm your eligibility with your accountant.

3. Review and Claim Every Eligible Small Business Tax Deduction

Sydney SMEs frequently miss or under-claim these:

• Home Office Expenses— 70 cents per hour worked from home (fixed rate method) or actual costs
• Vehicle & Travel— Logbook method or 88 cents per kilometre (up to 5,000 km)
• Prepaid Expenses(up to 12 months for businesses under $50m turnover) — software, insurance, rent, training
• Marketing, Website & Advertising
• Professional Fees(accounting, legal, bookkeeping)
• Staff Wages, Bonuses & Trainingpaid before 30 June
• Bad Debtswritten off before 30 June

4. The ATO Is Watching: Record-Keeping That Protects You

Frequently Asked Questions

Q: What does “installed ready for use” actually mean for the $20,000 write-off?
A: The ATO requires the asset to be physically in place and fully operational in your business by 30 June 2026 — not just ordered or paid for.

Q: Can I claim the $20k write-off for a work vehicle?
A: Yes, if the vehicle costs less than $20,000 and meets eligibility rules. Only the business-use portion applies.

Q: How do super contributions reduce my tax as a business owner?
A: Concessional contributions up to $30,000 are taxed at 15% inside super instead of your personal marginal rate.

Q: I missed super contributions in previous years. Can I still benefit?
A: Yes — if your total super balance is below $500,000 you may carry forward unused caps.

Q: When is the ideal time to book EOFY tax planning with an accountant?
A: Immediately. The best results come from planning in May, not waiting until July.
