Mastering Equipment Depreciation for Trades

23 October 2026 · 5 min read · By Heaney Accounting

What is Depreciation?

When you buy a big-ticket item like an excavator or a high-end laser level, you don't just expense the whole cost immediately. Instead, you claim the cost over the life of the item as it wears out.

Keep Your Records: Always keep your original purchase receipts, as the ATO requires proof of the date and cost to verify your depreciation claims.

Steps to Calculate Your Deduction

  1. Determine if the item is an immediate write-off or must be depreciated.
  2. Choose between the Prime Cost or Diminishing Value method.
  3. Calculate the effective life of the tool based on ATO tables.
  4. Apply the rate to the asset value each financial year.
