Tuan Duong
Tuan Duong is the Founder of Duo Tax Quantity Surveyors and the driving force behind Duo Tax’s growth into a national property services organisation. Tuan’s inspiration to help everyday Australians get ahead comes from his own experience as a property investor. After working hard to save for his first investment property, he was advised by his accountant to obtain a tax depreciation schedule from a quantity surveyor. Although Tuan had a strong background in Building Economics, he had limited knowledge at the time of how depreciation applied within Australian taxation. When he saw the tax savings the schedule helped identify, he realised how valuable this support could be for property investors. Recognising that many first-time investors were unaware of the deductions they may be missing, Tuan set out to combine his construction knowledge with a passion for helping others. He established Duo Tax Quantity Surveyors to help investors better understand and access the benefits of tax depreciation. Today, Tuan leads a national team that has helped more than 100,000 Australians make smarter property decisions. Duo Tax now offers a broader range of services across tax depreciation, property valuation, construction reporting and insurance support. Tuan is an Affiliate of the Australian Institute of Quantity Surveyors and a Registered Tax Agent with the Tax Practitioners Board. He is supported by a team that includes CPV Registered Property Valuers and Licensed Property Insurance Representatives.
