Repair or Improvement? Gather the Facts Before Coding It
Record the asset's condition before the work, what the supplier replaced and what the asset can do afterwards. Keep the invoice breakdown, quote and photographs together. The word “repair” on an invoice is not enough to decide tax treatment, especially where the work adds capability, replaces a substantial part or fixes a problem present when you acquired the asset.
What you’ll get from this guide: Prepare a clear before-and-after file for your adviser without guessing the expense or asset code.
- Save the condition and scope evidence before the work disappears behind a single invoice.
- Separate work that restores function from work that changes capability for review.
- Record the adviser decision against the original invoice breakdown.
A supplier's description is useful evidence, but it may combine maintenance, new equipment and installation in one line. This checklist is for an owner preparing the facts before the bookkeeper or tax agent finalises treatment.
Record the starting condition
Save the purchase date and any inspection showing the condition when you acquired the asset. Add a service report or dated photos showing the problem immediately before the work. Keep both dates visible so your adviser can distinguish the condition at purchase from the later fault.
Describe the asset in ordinary terms. Record what stopped working, whether it was still usable and what you asked the supplier to do. Avoid using the conclusion “fully deductible repair” as the description of the fault.
Fictional workshop machine: the supplier bills $3,900 for several different jobs.
| Work item | Before | After | Amount and evidence |
|---|---|---|---|
| Replace failed bearing | Machine stopped; service report identifies wear | Original operation restored | $900; report and parts invoice |
| Add digital controller | Manual adjustment only | New programmable functions | $2,400; specification and installation quote |
| Safety inspection | Inspection due | Inspection report issued | $600; separate service line |
$900 + $2,400 + $600 = $3,900. The breakdown makes review possible; it does not decide which amount is immediately deductible.
Ask for a useful invoice breakdown
Request separate descriptions and amounts for parts, labour, additions and unrelated services. Ask the supplier to explain the actual work, not to change the wording just to obtain a preferred tax outcome.
Where a quote changed during the job, keep the approved variation. If a new controller was added halfway through the repair, list it separately from the original maintenance request.
Show what changed after the work
Compare the old and new function, capacity and components. Attach specifications if the change is technical. Note whether the work replaced an entire asset or a component, and whether it addressed a pre-existing defect.
The ATO's repairs and replacement guidance explains why those distinctions affect the assessment. Use it to frame the question for your adviser rather than treating this worksheet as a tax-classification calculator.

Keep the decision with the equipment history
Record the chosen treatment, any split and the reason. Link capitalised amounts to the asset register while preserving the source invoice. If an entry is still awaiting a decision, make that status visible so it does not become final by accident.
The repair-or-replace cost comparison helps with a different decision: whether future operating costs justify keeping the equipment. A sensible business decision does not, by itself, determine the tax treatment of the work.
Key takeaways
- Save the condition and scope evidence before the work disappears behind a single invoice.
- Separate work that restores function from work that changes capability for review.
- Record the adviser decision against the original invoice breakdown.
Where to get help
Ask the supplier for scope and condition evidence, then a registered tax agent for tax treatment. Browse the tax records hub for purchase, use and disposal records.
