Arborist Students and New Climbers: How the Minimum Tax Threshold Affects Your First Year of Work
Published on August 4, 2026
The minimum tax threshold affects how much income tax an arborist student or new climber may pay during their first financial year of work. An Australian resident for tax purposes for the full financial year can generally claim the full $18,200 tax-free threshold. Part-year residents may receive a reduced threshold, while non-residents cannot claim it. Starting an arboriculture career can involve changing hours, casual shifts, allowances and income from other work. Understanding the tax-free threshold, income tax rates and tax deductions can help you protect your take-home pay and avoid an unexpected amount of tax payable when you lodge your tax return.
Understanding the Minimum Tax Threshold for New Arborists
The minimum tax threshold is commonly called the tax-free threshold. For most resident taxpayers, taxable income from $0 to $18,200 is generally free from income tax, while income from $18,201 to $45,000 is taxed at the applicable resident tax rate on the amount over $18,200. Your taxable income is not always the same as your salary. For tax purposes, the Australian Taxation Office (ATO) generally calculates taxable income by subtracting allowable tax deductions from assessable income, which may include salary, allowances, interest, dividends, capital gains and other income.

Your First Employment Forms Affect Your Take-Home Pay
When you begin work, your employer will usually ask you to complete a Tax File Number (TFN) declaration. You can use this form to claim the tax-free threshold if you are eligible, allowing your employer to calculate how much tax to withhold from your pay. When you claim the tax-free threshold, your employer will generally withhold tax once your pay exceeds $363 a week, $726 a fortnight or $1,573 a month. Your employer uses the applicable ATO tax tables, while your final tax payable is worked out when you lodge your tax return.
Multiple Jobs Can Change the Tax You Pay
Arborist students sometimes keep a second job while completing training or building climbing experience. When you receive income from more than one employer at the same time, you generally claim the tax-free threshold from only one employer, usually the employer paying the highest salary or wage. You may claim it from each employer if you are certain your total income for the financial year will be $18,200 or less. Income from every job is combined when your tax return is assessed. Two people with the same income will generally have the same income tax outcome, even when one person earns it from one employer and the other earns it from several employers.
Income Tax Rates Apply to Your Combined Taxable Income
Australian resident tax rates operate through tax brackets, so only the taxable income within each bracket is taxed at that rate. For 2026–27, the rates are nil from $0 to $18,200, 15% from $18,201 to $45,000, 30% from $45,001 to $135,000, 37% from $135,001 to $190,000 and 45% for each $1 over $190,000. These rates do not include the Medicare levy. Most resident taxpayers are generally subject to the Medicare levy, although a reduction or exemption may apply. The Medicare levy surcharge is separate and may apply when your income for surcharge purposes exceeds the applicable threshold and you, your spouse or your dependants do not have an appropriate level of private patient hospital cover.
Work Costs May Reduce Your Taxable Income
Tax deductions can reduce taxable income when an expense directly relates to earning your employment income. You must pay the cost yourself, keep suitable records and receive no reimbursement from your employer. Applicable expenses may include protective equipment, safety glasses, eligible protective footwear, sunscreen used for outdoor work and tools used in your employee duties. Depending on the item, you may claim its cost or decline in value, but you must exclude private use. Ordinary clothing, private travel, home office running expenses claimed using the fixed rate method and costs paid or reimbursed by your employer are generally not deductible.

Your residency, other income, eligible deductions and Medicare obligations can all affect the final amount payable. Check your first payslip, keep evidence of work costs and review your position when your income changes.
