You are the registered tax agent and approached by your client Daniel. He is currently operating a small coffee shop with his wife (50:50 ownership) in the form of partnership. He asks you for advice about how to work out the tax on the profit from their partnership business if it is expected to be $90,000 for the 2018-19 income year, and which tax documentation should be prepared and lodged to finalise their tax affairs for the 2018-19 income year provided both Daniel and his wife are your clients?
