Commercial Property Depreciation: Division 40 Explained

Commercial property offers a standout tax advantage many investors miss: you can claim

second-hand plant & equipment (Division 40) — something residential investors generally can’t do on properties purchased after 9 May 2017. For business owners and commercial investors, that can translate into tens of thousands of dollars in extra after-tax cash flow, especially when fit-outs and equipment are involved.

Commercial vs Residential Depreciation: The short version

Real numbers investors care about

• Older commercial assets can still pay: Even a 50-year-old site can produce ~$15–$20k in first-year plant & equipment deductions when assessed correctly.

• Case study: A near-new $4M industrial asset with mezzanine and crane delivered about $60k in year-one depreciation, with $40–$55k p.a. for many years thereafter.

• Retail & medical fit-outs: High-spec, motorised, and short-life assets (e.g., ducted A/C, lighting, kitchen equipment) turbo-charge Division 40 claims.

Tip: Depreciation isn’t just “paper.” It’s cash you keep — either by reducing tax payable or improving effective yield on your capital.

Fit-outs, scrapping & first-year write-offs (the big missed opportunity)

If you acquire a commercial property with an existing fit-out you now own, and you decide to refurbish, the remaining undepreciated value of that old fit-out can often be written off immediately when scrapped. Then you start a new schedule on the fresh fit-out. For busy operators, this can mean a six-figure deduction in year one — a game-changer for cash flow.

By asset type: why outcomes differ

Not all commercial assets are equal. A basic warehouse (tilt-panel, minimal finishes) can have modest per-sqm construction and lower depreciation relative to a high-spec retail or medical fit-out. Luxury retail can run 10–15× the build cost of a bare warehouse on a per-sqm basis — and that difference often flows directly into larger Division 40 claims.

Structures: trusts, companies & SMSFs

Common scenario: a family trust owns the building (claims building & common strata). Your operating company leases and runs the business from the premises and claims depreciation on the new fit-out. If you demolish an inherited fit-out you own, the trust may claim the scrapping deduction; the company then depreciates the replacement fit-out.

What to do next (simple 5-step flow)

1. Shortlist the asset using an evidence-led brief. If you’re new to commercial, start here: How to start investing in commercial real estate.

2. Estimate depreciation early: Before you buy, get a quantity surveyor estimate for Division 40 and capital works.

3. Model post-tax cash flow: Combine rent, outgoings, interest, and depreciation to compare “apples with apples” across options.

4. Lock in due diligence: Protect your position with tight DD clauses. Read: Commercial due diligence with case studies.

5. Order the schedule post-settlement: A commercial depreciation schedule often starts from about ~$700 and usually pays for itself quickly.
