The team at Duo Tax made things so easy for our interstate property, liaising with our agents directly. We didn’t even have to lift a finger. And to top things off, the result achieved in their depreciation schedule, came out better than expected!

The team were highly efficient and comprehensive from the first point of contact, explaining their processes in detail and then delivering in what was outlined. We will definitely be using their services again in the future and would recommend them to others.
