Tools and Equipment

Every tool you purchase for your hvac technician work is deductible. Under the instant asset write-off (until 30 June 2026), items under $20,000 each can be claimed in full in the year of purchase.

  • Refrigerant recovery machines and manifold gauges
  • Vacuum pumps and leak detectors
  • Recovery cylinders and refrigerant handling tools
  • Electrical test equipment (multimeters, clamp meters)
  • Sheet metal tools and ductwork equipment
  • Pipe cutters and flaring tools
  • Nitrogen test sets and pressure gauges
  • Diagnostic tablets and software
  • Extension ladders and step ladders
  • Service vehicle fit-out and racking
  • Consumables — blades, discs, fixings and other items used up in your work
  • Tool repairs and maintenance on existing equipment
  • Toolbox, bags and storage systems

Snap every receipt immediately with Dext — it extracts the details automatically and stores them in ATO-compliant format. The ATO audits tradies and can request records for up to 5 years.

Vehicle Deductions — Updated to 88 Cents Per Kilometre

Your vehicle is typically your biggest tax deduction. The cents per km rate increased to 88 cents per km for 2025–26 (up from 85c), but the logbook method almost always produces a larger deduction for hvac technicians who drive more than 5,000 business kilometres per year.

Keep a 12-week ATO logbook, calculate your business-use percentage, then claim that percentage of all annual vehicle costs — fuel, rego, insurance, loan interest, servicing and depreciation.

The instant asset write-off threshold drops from $20,000 to $1,000 on 1 July 2026. If you need new tools or equipment, buying before 30 June gets you the full deduction this financial year instead of depreciating the cost over several years.

What can a aircon tech claim on tax in Australia?

The main deductions for hvac technicians are tools and equipment, vehicle expenses (logbook method), licences and training, PPE and safety gear, insurance premiums, phone and internet (work use %), accounting fees and super contributions. Keep receipts for everything.

Does a aircon tech need to keep a vehicle logbook?

Yes if you want the maximum vehicle deduction. The logbook method lets you claim a percentage of all vehicle costs — fuel, rego, insurance, loan interest, servicing. A 12-week logbook is valid for 5 years. The cents per km alternative (88c/km in 2025–26) is capped at 5,000km — most tradies do better with a logbook.

Can a aircon tech claim tools under $300?

Sole traders and business owners can claim tools of any value under the instant asset write-off rules (until 30 June 2026, items under $20,000 each). After 30 June 2026, items over $1,000 must be depreciated. Employees can claim tools under $300 immediately but must depreciate tools over $300.

## Vehicle & Travel Deductions for HVAC Technicians Your van or ute is one of your biggest tax deduction opportunities. The ATO recognises that HVAC techs travel constantly between jobs — from residential air conditioning installations in suburban Melbourne to commercial refrigeration work across Sydney's CBD. **Claiming vehicle expenses has two methods:** **Method 1: Cents-Per-Kilometre (Simpler)** For the 2025–26 tax year, the ATO rate is **88 cents per kilometre**. This is the easiest approach if your annual work-related driving stays under 5,000 km or you don't have detailed records. Calculate: Total work-related km × 0.88 = your deduction. Example: You drive 12,000 km annually for jobs. Claim: 12,000 × $0.88 = **$10,560 deduction**. You'll need a logbook for four weeks to establish your work-travel percentage, then apply that ratio across the full year. Many HVAC techs underestimate this — don't forget the drive from your home office to the first job of the day or between multiple call-outs. **Method 2: Actual Expenses (Potentially Higher)** Track every cost: fuel, servicing, insurance, registration, tyres, repairs, and depreciation. This method suits techs with high-mileage schedules or expensive vehicles. If your van's running costs exceed 88c/km, this method wins. A typical tradie van consuming fuel at higher rates in regional areas often justifies actual expenses. Keep all receipts in a folder — use Tradify or similar software to photograph and log them automatically. **Critical point:** You can only claim the work-related percentage. If you drive 20,000 km yearly and 60% is work-related, claim 12,000 km at 88c. Don't claim travel to your permanent place of work (even if it's a depot you own). Do claim travel between multiple job sites on the same day. ## Tools, Equipment & The $20,000 Instant Asset Write-Off HVAC technicians invest heavily in specialised tools: digital manifolds, nitrogen cylinders, thermal imaging cameras, evacuation pumps, and diagnostic equipment. Until 30 June 2026, Australia's **$20,000 instant asset write-off** (extended from the standard $1,000 threshold) is still active, and you need to maximise this window. **What qualifies:** - Diagnostic and testing equipment under $20,000 - Gauges, valves, and hoses - Power tools (impact wrenches, cordless drills, angle grinders) - Vehicle equipment mounted in your van - Safety gear (but not everyday clothing) - Laptops and tablets used for job management (e.g., with Xero or Tradify) **What doesn't qualify:** - Land, buildings, or structural improvements - Intangible assets (software licenses over 12 months) - Motor vehicles (they're depreciated differently) - Stock or raw materials **The strategy:** If you're planning to buy a digital manifold ($3,500), evacuation unit ($8,000), and new diagnostic software setup ($2,500), bundle these purchases before 30 June 2026 and claim the total ($14,000) instantly. Post 30 June 2026, you'll return to $1,000 threshold, meaning larger purchases depreciate over multiple years. Keep invoices showing purchase date and cost. The ATO matches large purchases against suppliers' records, so accuracy matters. **Depreciation After $20k Write-Off:** Equipment exceeding $20,000 is depreciated over its effective life. A specialised air conditioning refrigeration unit lasting 10 years depreciates at 10% annually. Track these on a depreciation schedule — Xero handles this automatically. ### Common HVAC Deductions Comparison | **Expense Type** | **Deductible?** | **Documentation** | **Common Amount (Annual)** | |---|---|---|---| | Van fuel & servicing | Yes (work %) | Logbook + receipts | $2,000–$4,500 | | Tools & equipment under $20k | Yes (100%) | Invoice & receipt | $1,500–$5,000 | | Business uniforms (branded shirts) | Yes | Purchase receipts | $300–$800 | | Training & qualifications | Yes | Course fees & materials | $500–$2,000 | | Phone (business use %) | Partial | Mobile contract | $200–$600 | | Home office (dedicated space) | Yes | Area calculation | $1,500–$3,000 | | Vehicle insurance | Yes (work %) | Policy & premium | $1,200–$2,000 | | Professional memberships | Yes | Membership fees | $100–$500 | | Work boots & safety gear | No (general clothing) | — | — | | Meals during work travel | No (general living) | — | — |

**TIP:** Many HVAC techs miss the "work-related phone" deduction. If 50% of your calls are job-related, claim 50% of your annual phone bill. Similarly, if you use your internet to invoice clients through software like Tradify, claim a percentage of your NBN bill. Keep a usage diary for one month to establish your percentage.

## Superannuation & Small Business Tax Offset HVAC technicians operating as sole traders or partnerships should review their superannuation contribution strategy. The ATO allows you to claim personal super contributions as a deduction (up to $27,500 per year, with a $30,000 cap including employer contributions in 2025–26). If you earn $50,000 annually and contribute $10,000 to super, you reduce your taxable income to $40,000. At a 37% tax rate (plus Medicare Levy), this saves you approximately $3,900 in tax — money that goes into retirement savings instead of the ATO. Additionally, you're eligible for the **Small Business Tax Offset** if your aggregated turnover is under $50 million. This provides a tax reduction of up to $1,035 (2025–26). Ensure your accountant claims this. If you employ apprentices, the **Apprentice Payroll Tax Exemption** applies in most states, and you're eligible for the **Apprentice Wage Deduction** at the federal level. ## Frequently Asked Questions

Can I claim the cost of Freon/refrigerant as a deduction?

Yes. Refrigerant is a consumable cost directly used in your service delivery. It's fully deductible as a materials or direct cost, not depreciated. Keep invoices from your supplier. However, if you purchase refrigerant that remains in your van as stock at year's end, you must account for closing stock value and reduce your deduction accordingly. Most HVAC techs claim this correctly — it's one of the bigger annual deductions alongside fuel.

Do I need insurance to claim tax deductions as an HVAC tech?

The ATO doesn't require it, but you absolutely should have it. Public liability and tools insurance are business essentials, and the premiums are fully deductible. BizCover specialises in tradie insurance and can cover your tools, vehicle, and liability from around $50–$100 monthly. Claim the full premium against your tax.

What if I work both residential and commercial HVAC — how do I split deductions?

Allocate expenses proportionally to income. If 60% of your revenue is residential and 40% is commercial, apply that split to shared costs like vehicle running, phone, and office expenses. Keep records showing the breakdown (invoices, job quotes, or annual revenue reports). Use separate cost codes in Xero or Tradify to track this automatically throughout the year.
