Navigating the Nitty-Gritty of Trade Tax Deductions

18 October 2026 · 6 min read · By Heaney Accounting

For tradies, tax time shouldn't be a guessing game. Many builders and sparkies leave money on the table simply because they aren't sure what qualifies as a legitimate business expense. This guide helps you identify exactly what you can claim.

Commonly Missed Deductions

  • Protective clothing and specialised gear
  • Union fees and industry association memberships
  • Mobile phone plans for business calls
  • Small tool replacements under $300

Understanding Asset Depreciation

Large equipment like excavators or heavy-duty generators are not fully deductible in one year. Instead, you claim the decline in value over the life of the asset. Keeping a detailed asset register is essential for this process.

Pro Tip: Always keep a photo or digital scan of your receipts. Thermal paper receipts fade quickly, and the ATO will not accept a blank piece of paper if your records are audited.

  1. Create a dedicated folder for all business invoices
  2. Use a cloud accounting app to snap photos of receipts on the go
  3. Separate business bank statements from personal spending
