Pest control is a licensed trade in every Australian state and territory. You need both a pest management technician licence (individual) and a pest management business licence (for the entity) before carrying out any work. Licensing fees, mandatory training, and chemical handling accreditation are all deductible. Tax obligations include income tax on trading profit (sole trader) or company tax at 25% (Pty Ltd base rate entity), GST registration once turnover hits $75,000, and careful record-keeping for chemical purchases and vehicle expenses. Unlike cleaners and construction trades, pest control is not separately listed as a TPAR industry, so TPAR obligations are minimal unless your work overlaps with building and construction services (such as pre-construction termite barriers).
What business structure do Pest Control use?
The common patterns for Pest Control are: Sole trader: simplest setup, ABN registration only, suits one-person operators running a van-based pest service under roughly $100k profit, Pty Ltd company: limited liability for chemical handling risk, access to 25% base rate entity tax, better suited once profits grow or you employ technicians, Family trust: occasionally used for income splitting, but does not remove personal licensing obligations (each technician must hold their own individual licence regardless of business structure). The right structure depends on revenue, liability exposure, and personal circumstances, covered below.
What licences do pest control operators need?
Every state and territory requires pest control operators to hold both an individual technician licence and a business licence. The specific names and issuing bodies differ by state:
NSW: pest management technician licence and pest management business licence (NSW EPA). QLD: pest management technician licence (QBCC). VIC: pest control licence (Department of Health). WA: pest management technician's licence and pest controller's licence (Department of Health). SA: licensed pest controller (SA Health). TAS: pest control operator licence (Department of Health). ACT and NT: territory-specific licensing through health departments.
Licence application fees, renewal fees, and the cost of mandatory training courses (Certificate III in Pest Management or equivalent) are all tax deductible as ongoing trade expenses. The initial qualifying training to enter the trade is not deductible as it is considered personal capital expenditure, but refresher courses, advanced modules (timber pest, fumigation endorsements), and CPD are deductible.
Pest control licence renewal fees, mandatory training, and CPD costs are deductible as ongoing trade expenses. Initial qualifying training is not deductible.(ITAA 1997 s 8-1 (general deduction) and s 25-5 (tax-related expenses); ATO guidance ATO deductions for licence fees and training)
When do pest controllers need to register for GST?
GST registration is mandatory once your annual turnover reaches $75,000 (gross business income, not profit). An established pest control operator servicing residential and commercial clients regularly will typically cross this threshold within the first year or two.
Voluntary registration below the threshold lets you claim GST credits on chemicals, equipment, vehicle expenses, and licensing fees. The trade-off: you charge 10% GST on every invoice and lodge BAS quarterly or monthly.
Pest control has a seasonal revenue pattern (termite season peaks in spring and summer), so operators must monitor rolling 12-month GST turnover and register within 21 days of reasonably expecting to cross $75,000. Late registration triggers penalties and backdated GST on all invoices from the date you should have registered.
GST registration is compulsory when annual turnover reaches $75,000. Voluntary registration is available below this threshold.(A New Tax System (Goods and Services Tax) Act 1999 s 23-15; ATO guidance ATO GST registration guide)
How do I claim vehicle expenses for a mobile pest control business?
The work vehicle is the single largest expense for most pest control operators. The van or ute functions as a mobile workshop: spray rigs, chemical tanks, ladders, inspection tools, and safety equipment are permanently fitted or stored in it.
Two methods: cents-per-km (88 cents per business kilometre, capped at 5,000 km, giving a maximum $4,250 deduction) or the logbook method (actual running costs multiplied by business-use percentage from a 12-week representative logbook).
For a full-time pest controller running 4-6 jobs per day with equipment permanently installed in the vehicle, logbook method will almost always give a larger deduction. Running costs include fuel, servicing, registration, insurance, tyres, interest on finance, and decline in value.
Vehicle type matters: passenger vehicles (including many vans under 1-tonne payload) are subject to the car depreciation limit of $69,674 for 2025-26. Commercial vans and utes designed to carry more than 1 tonne payload are not subject to the car limit, and decline in value is calculated on the full cost.
Vehicle expenses can be claimed via cents-per-km (88c/km, max 5,000 km) or logbook method (actual costs x business-use %). Passenger vehicles are subject to the car depreciation limit.(ITAA 1997 Division 28 (car expenses) and Division 40 (decline in value); ATO guidance ATO vehicle and travel expenses guide)
Can I claim chemicals, baits, and safety equipment?
All chemicals, baits, traps, and consumables purchased and used in providing pest control services are deductible as business expenses (cost of goods sold) in the year of purchase. This includes termiticides, general pesticides, rodent baits, insect gel baits, fumigation chemicals, and biological control agents.
Safety equipment required for chemical handling is also deductible: respirators, chemical-resistant gloves, overalls, boots, eye protection, and spill containment kits. If you are GST-registered, claim GST credits on all these purchases.
Chemical storage requirements vary by state but typically include locked, ventilated storage in accordance with AS 2507 (Storage and Handling of Pesticides). The cost of compliant storage cabinets, bunding, and ventilation systems is deductible as a business expense or depreciating asset depending on cost.
Chemicals, baits, and safety equipment used in providing pest control services are deductible as business expenses. Chemical storage infrastructure is deductible or depreciable.(ITAA 1997 s 8-1 (general deduction); ATO guidance ATO deductions for tools, equipment, and other expenses)
Contractor vs employee: the written contract is decisive
The High Court reset the contractor/employee test in 2022. Where there is a comprehensive written contract that is not a sham, classification turns principally on the rights and obligations established by that contract — not on the day-to-day conduct of the parties. Get the engagement contract right at the start; do not rely on post-contract behaviour to recharacterise the relationship later.
This matters because misclassification exposes the engager to PAYG withholding shortfalls, super guarantee charge (with the contractor-deemed-employee extension under SGAA 1992 s 12(3)), and payroll tax. It also affects whether the worker can deduct business expenses and whether PSI rules engage.
Contractor vs employee classification is determined principally by the rights and obligations in the written contract, not by post-contract conduct.(CFMMEU v Personnel Contracting Pty Ltd [2022] HCA 1; ZG Operations Australia Pty Ltd v Jamsek [2022] HCA 2 (companion case); ATO guidance TR 2023/4 (employee vs independent contractor))
Home running costs: PCG 2023/1 fixed-rate vs actual cost
Most workers in this trade do some admin from home — quoting, invoicing, scheduling, BAS prep. From 1 July 2024 the ATO fixed-rate method is 70c per hour worked from home and covers electricity, gas, internet, mobile, stationery and computer consumables. You cannot also claim those bills separately under the fixed rate. You can still separately depreciate office furniture and equipment used at home.
FY 2024-25 and FY 2025-26 rate: 70c/hr. FY 2022-23 and FY 2023-24 rate: 67c/hr. The fixed rate requires a contemporaneous record of actual hours worked from home — a timesheet, calendar or app log. Estimates and four-week samples are no longer accepted for the fixed rate method (they remain valid for the actual cost method).
The fixed-rate method for home office running costs is 70c per hour from 1 July 2024 and requires a record of actual hours worked from home.(PCG 2023/1 (as amended); ITAA 1997 s 8-1; ATO guidance TR 93/30; TR 2024/3)

Vehicle and travel costs
The work vehicle is the backbone of a pest control business, functioning as a mobile workshop with spray rigs, chemical tanks, and inspection tools permanently installed. Most full-time pest controllers should use the logbook method: keep a 12-week representative logbook, then apply the business-use percentage to all running costs for the year. For a pest controller running 4-6 jobs per day, business use is typically 80-90%. The logbook is valid for five years unless circumstances change. Cents-per-km (88c/km, max 5,000 km) caps at $4,250, which never covers actual costs for a vehicle carrying thousands of dollars in fitted equipment. Spray rig fit-outs and chemical tank installations are separate depreciating assets claimed independently from the vehicle itself.
Capital allowances and equipment
The instant asset write-off threshold for small business entities (turnover under $10 million) is $20,000 per asset for 2025-26. A $6,000 spray rig, a $3,500 thermal imaging camera for termite inspections, or a $12,000 vehicle-mounted chemical tank system can each be written off in full in the year of purchase. For assets above $20,000 (a $45,000 fully fitted pest control van, for example), the simplified depreciation pool applies: 15% in the first year, 30% in subsequent years. If the van is a passenger vehicle, the car depreciation limit of $69,674 caps the depreciable amount. Chemical storage cabinets and bunding under $300 are immediately deductible.
Common ATO audit triggers for Pest Control
High vehicle claims without a logbook to substantiate business-use percentage
Cash jobs not declared (ATO cross-references bank deposits and lifestyle indicators against industry benchmarks)
Large chemical purchases with no corresponding income to justify the volume
Licence and training costs claimed as business deductions when they relate to initial qualifying training (not deductible)
Private use of the work vehicle not apportioned (weekend personal use of a fitted van)
Repeated business losses claimed against other income without meeting non-commercial loss tests (Division 35)
Frequently asked questions
Is pest control covered by TPAR?+
Pest control is not separately listed as a TPAR industry. You generally do not need to lodge a Taxable Payments Annual Report for paying pest control subcontractors. The exception: if your pest control work is performed as part of a broader building and construction contract (for example, pre-construction termite barriers as part of a new build), it may fall under the building and construction TPAR category. If primarily servicing residential and commercial clients directly, TPAR does not apply.
Can I claim my pest management licence fees?+
Yes. Annual state pest management technician licence renewals, business licence fees, fumigation endorsements, and chemical handling accreditation renewals are all fully deductible as ongoing trade expenses. Advanced training courses (timber pest inspection, fumigation) are also deductible. Your initial Certificate III in Pest Management or equivalent qualifying training to enter the trade is not deductible, as it is considered personal capital expenditure.
How do I handle the seasonal nature of pest control income?+
Pest control revenue peaks during spring and summer (termite swarming season, increased insect activity) and drops in cooler months. PAYG instalments set from your last return may overshoot winter-quarter income. You can vary instalments downward with a reasonable estimate of year-end income. Set aside 25-30% of every payment during peak months into a separate tax/GST account to cover lean-quarter obligations. Keep job-by-job records so BAS figures are easy to reconcile during seasonal swings.
What are the rules for storing chemicals at my premises?+
Chemical storage must comply with AS 2507 (Storage and Handling of Pesticides) and your state's specific regulations. Typically this means a locked, ventilated storage area (cabinet or shed), bunding to contain spills, safety data sheets accessible for all chemicals on site, and separation from food, living areas, and incompatible substances. The cost of compliant storage infrastructure (cabinets, bunding, ventilation) is tax deductible as a business expense or depreciating asset. Non-compliance can result in licence suspension or cancellation.
