BAS Preparation for Tree Services: Complete Guide for Arborists

Business Activity Statements are a fundamental compliance requirement for Australian arborists, yet they remain a significant source of stress for many tree service operators. BAS preparation for tree services involves unique considerations around GST on mixed supplies, fuel tax credits, and cash flow management during seasonal fluctuations. This comprehensive guide walks you through everything you need to know about BAS for your arborist business.

Understanding BAS for Arborist Businesses

A Business Activity Statement is a form submitted to the Australian Taxation Office (ATO) to report and pay several tax obligations. For most tree services businesses, BAS primarily involves reporting GST collected and paid, PAYG withholding from employee wages, and PAYG instalments toward your own income tax.

Who Needs to Lodge BAS?

You must register for GST and lodge BAS if your tree services business has an annual turnover of $75,000 or more. However, you can voluntarily register even below this threshold, which is often beneficial for arborists due to significant equipment purchases.

Benefits of voluntary GST registration: – Claim GST credits on major equipment purchases – Appear more professional to commercial clients – Claim fuel tax credits (discussed below) – Build good compliance habits early

BAS Reporting Periods

The ATO offers different reporting cycles depending on your business size:

Annual Turnover	Reporting Period	Lodgement Deadline
Under $10 million	Quarterly	28 days after quarter end
$10 million or more	Monthly	21 days after month end
Any (by election)	Monthly	21 days after month end

Most tree services businesses report quarterly, which means four BAS lodgements per year.

BAS Deadlines for 2026

Missing BAS deadlines results in penalties and interest charges. Here are the key dates every arborist needs to know for 2026.

Quarterly BAS Due Dates 2026

Quarter	Period	Paper Lodgement	Electronic Lodgement
Q3 2025-26	1 Jan – 31 Mar 2026	28 April 2026	28 April 2026
Q4 2025-26	1 Apr – 30 Jun 2026	28 July 2026	28 July 2026
Q1 2026-27	1 Jul – 30 Sep 2026	28 October 2026	28 October 2026
Q2 2026-27	1 Oct – 31 Dec 2026	28 February 2027	28 February 2027

Important Notes: – If the due date falls on a weekend or public holiday, you have until the next business day – Tax agent clients typically receive extended lodgement deadlines – The December quarter deadline is extended to 28 February to accommodate the holiday period

Monthly BAS Due Dates

For arborists lodging monthly, BAS is due on the 21st day of the following month. If you use a tax agent, this may be extended to the 25th.

What’s Included in Your BAS

Understanding each component of the BAS helps ensure accurate reporting and maximises your entitled credits.

GST Section

GST Collected (1A): The total GST you’ve charged on your tree services during the reporting period. For most arborist work, this is 10% of the GST-inclusive price.

GST Paid (1B): The GST you’ve paid on business purchases – equipment, fuel, consumables, subcontractors, and other expenses.

GST Payable/Refundable: The difference between collected and paid. Most established arborists pay GST quarterly, but new businesses making major equipment purchases may receive refunds.

PAYG Withholding

If you have employees, you must report the tax withheld from their wages. This includes: – Regular employees on wages – Directors receiving a salary – Contractors who haven’t provided an ABN (unusual in arboriculture)

PAYG Instalments

These are prepayments toward your expected income tax liability. The ATO calculates instalments based on your reported income, or you can calculate your own using the GDP-adjusted notional tax method.

Fuel Tax Credits

This is a significant opportunity for arborists that many overlook. You can claim credits for fuel used in: – Chainsaws and other power tools – Wood chippers and stump grinders – Off-road vehicle use – Generators and pumps

We’ll discuss this in detail later in this guide.

Common BAS Mistakes Arborists Make

After years of working with tree services businesses, we’ve identified the most frequent BAS errors and how to avoid them.

Mistake 1: Incorrect GST Treatment of Mixed Supplies

Some arborist services have complex GST implications. For example:

Tree removal with timber retention: If you remove a tree and keep the timber for firewood sales, the GST treatment depends on the arrangement. If it’s a separate sale of goods, GST applies differently than if it’s factored into the removal quote.

Insurance work: Jobs paid directly by insurance companies still attract GST, even though the homeowner isn’t paying directly.

Council and government work: Most government contracts are GST-inclusive, but verify this for each contract.

How to avoid: Maintain clear documentation of the nature of each job and consult with your accountant on unusual arrangements.

Mistake 2: Claiming GST on Non-Deductible Items

You cannot claim GST credits on certain expenses, including: – Entertainment expenses – Penalties and fines – Private portions of mixed-use assets – Purchases from unregistered suppliers (no GST was charged)

How to avoid: Review your GST claims against the list of blocked credits and ensure proper apportionment for mixed-use items.

Mistake 3: Overlooking Fuel Tax Credits

Many arborists either don’t claim fuel tax credits or underestimate their entitlement. For a busy tree services operation, this can mean thousands of dollars left on the table annually.

How to avoid: Track all fuel usage by equipment type and calculate credits using current ATO rates.

Mistake 4: Cash vs Accrual Confusion

Most small businesses use cash accounting for GST – you report GST when money changes hands. However, some businesses use accrual accounting, reporting GST when invoices are issued or received, regardless of payment.

Common error: Mixing methods by claiming GST on purchases when you pay but reporting sales when invoiced.

How to avoid: Confirm your GST accounting method and apply it consistently to all transactions.

Mistake 5: Poor Record Keeping

Without proper records, you risk: – Missing legitimate deductions and credits – Being unable to substantiate claims during an audit – Making errors in GST calculations – Facing penalties for inadequate documentation

How to avoid: Implement a systematic approach to capturing receipts and invoices. Cloud accounting software with receipt capture apps makes this manageable.

Mistake 6: Ignoring Depreciation Schedules

While depreciation isn’t directly reported on BAS, incorrect asset registers lead to errors in: – Instant asset write-off claims – Calculating GST on asset sales – Year-end tax reporting

How to avoid: Maintain accurate equipment registers and update them when purchasing or disposing of assets.

Mistake 7: Late Lodgement

Even if you can’t pay the full amount, you should still lodge on time. Late lodgement attracts penalties starting at $313 for small businesses and increasing for larger operations.

How to avoid: Set calendar reminders two weeks before each deadline and use tax agents who provide lodgement reminders.

GST Tips Specifically for Arborists

The arboriculture industry has unique GST considerations. Here are strategies to optimise your GST position.

Claiming GST on Equipment Purchases

Major equipment purchases often result in GST credits exceeding GST collected, leading to refunds. Ensure you:

• Obtain proper tax invoices for all purchases over $82.50
• Claim GST in the period when equipment is delivered or paid (depending on your accounting method)
• For hire purchase, claim full GST upfront on the purchase price

GST-Free Sales to Understand

While most arborist services are taxable, some situations may be GST-free: – Exported services (rare in arboriculture) – Services provided as an employee of another business – Sales under the GST registration threshold (if not registered)

Managing GST on Subcontractor Payments

When engaging subcontractors: – Verify they’re registered for GST before paying – Only claim GST credits if they provide a valid tax invoice – Keep subcontractor details for your Taxable Payments Annual Report (TPAR)

Asset Sales

When selling old equipment: – GST applies to sales by GST-registered businesses – Include proceeds as income in your GST calculations – Adjust your asset register accordingly

Fuel Tax Credits: A Major Opportunity

Fuel tax credits represent one of the largest overlooked tax benefits for arborists. Here’s how to maximise this entitlement.

What Qualifies

You can claim fuel tax credits for fuel used in:

Eligible Equipment: – Chainsaws and pole saws – Wood chippers – Stump grinders – Leaf blowers and other power tools – Generators – Water pumps – Skid steer loaders – Off-road portions of vehicle use

Eligible Fuels: – Petrol – Diesel – LPG

Current Rates (2026)

Fuel tax credit rates change regularly. As of 2026, typical rates are:

Fuel Type	Use	Credit Rate (approx.)
Diesel	Heavy vehicles (road)	$0.20-0.25/litre
Diesel	Off-road equipment	$0.47-0.50/litre
Petrol	Power equipment	$0.47-0.50/litre

*Note: Rates change twice yearly. Always verify current rates on the ATO website.*

Calculating Your Entitlement

Example calculation for an arborist:

Monthly fuel usage: – Chainsaws (petrol): 150 litres – Chipper (diesel): 400 litres – Stump grinder (diesel): 200 litres – Vehicle off-road portion (diesel): 100 litres

Estimated monthly fuel tax credits: – Chainsaws: 150L x $0.48 = $72 – Chipper: 400L x $0.48 = $192 – Stump grinder: 200L x $0.48 = $96 – Off-road vehicle: 100L x $0.48 = $48

Total monthly credits: $408 Annual benefit: $4,896

Record-Keeping Requirements

To claim fuel tax credits, maintain records showing: – Fuel purchases (receipts) – Usage allocation by equipment type – Business kilometres for vehicles – Calculation methodology

BAS Preparation Process Step-by-Step
