Work-From-Home Deduction: 70¢ Fixed Rate Method

If you’re working from home — even part-time — you may be eligible to use the ATO’s fixed rate method, now set at 70 cents per hour for the 2024–25 income year.

What’s Covered:

  • Electricity and gas (lighting, heating/cooling)
  • Phone and internet costs (home and mobile)
  • Computer consumables and stationery

You can’t claim these items separately if you use the fixed rate.

What You Still Can Claim Separately:

  • Decline in value (depreciation) of work equipment (e.g. desk, monitor, laptop)
  • Repairs and maintenance of those assets
  • Cleaning costs (if you use a dedicated home office)

Record Keeping Requirements:

  • Keep a record of all actual hours worked from home (no estimates allowed)
  • One bill or receipt for each category of running expense is required

Superannuation Guarantee: New Rate

From 1 July 2025, the Super Guarantee (SG) rate increases to 12%.

  • Applies to employees’ ordinary time earnings
  • Businesses should update payroll systems accordingly

Small Business Reminders

  • Instant Asset Write-Off: The $20,000 threshold remains for eligible small businesses (turnover < $10M) for 2024-25 Financial Year
  • GST Registration: Still required if turnover exceeds $75,000 in any 12-month period
  • PAYG Instalments: Consider varying instalments if income has changed.

Other Key Considerations

  • Division 293 Tax: Still applies to those earning over $250,000 — reducing super tax concessions
  • Private Health Insurance Rebate: Remains income-tested. If you earn above the threshold, you may not be eligible for a rebate.
  • Audit Insurance: With increased ATO activity, audit insurance is worth considering for added peace of mind

✔️ Use a registered tax agent like Healthbiz Accounting to:

  • Access extended lodgement deadlines
  • Maximise deductions (legitimately)
  • Ensure full ATO compliance

✔️ Don’t leave it until June — the earlier you plan, the more options you have!
