Duo Tax

What Duo Tax does

Duo Tax (legally Duo Tax Quantity Surveyors) is an Australian professional services firm that prepares tax depreciation schedules, property valuations and construction cost estimations for property investors. Founded in 2015 and headquartered in Homebush, NSW, the firm operates from 22+ office locations across Australian states and territories, employing 59 staff with reported 50+ years of combined quantity surveying experience. The core service is the production of ATO-compliant depreciation schedules that allow investors to claim building and plant write-offs over the effective life of an investment property, alongside insurance replacement valuations and construction estimation work.

The firm's product surface extends beyond one-off reports into a free multi-calculator suite and the branded Duo Tax Improvement Report™, with adjacent valuation services offered through the DuoInsurance sub-brand. Underlying the operation is a 14M+ Australian property database accumulated since inception and a 50,000+ report completion track record, which the firm positions as the basis for faster turnaround and more accurate cost apportionment versus greenfield QS practices.

Duo Tax generates revenue on a per-engagement basis: tax depreciation schedules are priced per property, with valuations and construction estimates priced per scope. Distribution is hybrid, combining direct-to-investor marketing (130,000+ subscribers, YouTube content channel) with a structured partner referral network across accountants, lenders, buyer's agents, property managers and financial planners, plus multi-language site versions targeting Vietnamese, Chinese and Korean-Australian property investors. The firm has scaled organically without disclosed external funding.
