I recently engaged Patrick from Quantity Surveyor to prepare a depreciation schedule for my investment properties and I'm very pleased with the service. The process was smooth, communication was clear, and the report was delivered on time. The schedule was detailed and easy to understand, which will help maximise my tax deductions. I would happily recommend Patrick to other property owners.

I used TDQS to prepare a tax depreciation report for a commercial property I bought in Queensland. I was very impressed by the level of detail in the report and the fact they were able to identify $193,946 of depreciation during their on-site visit. I also loved the professionalism of TDQS and their friendly customer service. When I buy another property, I'll definitely use TDQS to prepare a tax depreciation report for that property as well.

Who We Help

Commercial property investors & their advisors

Direct commercial owners

Office, retail, industrial or hospitality, held in your name or entity.

Syndicates & SMSFs

Pooled or super-held property where unit-holders feel every after-tax dollar.

Fund managers & REITs

Active portfolios where a rebuild quietly lifts distributable income.

Family offices

Generational portfolios where small uplifts compound.

Developers who held the build

Built-to-own assets where capital works detail rarely makes the schedule.

High-net-worth investors

Sophisticated holders who’d rather not subsidise the ATO.

Hotel & hospitality owners

FF&E heavy assets where templates leave six figures on the table.

Accountants & advisors

We sit behind you. The schedule goes to you, not your client.
