I have had this issue three years in a row. I am self-employed and I have three sources of self-employed income. One is a business partnership, one is work as a regulated health professional (GST exempt) and one is consultancy work. One of the businesses I provide consultancy work for issues T4A slips providing a total of how much work I was paid for in the year. However, when I import it, or even enter it manually, it adds the income to the first business on my self-employed list, which is the partnership business. This is incorrect. I have searched high and low for a manual way to change this and assign it to my consultancy business, and I cannot find a way. The last two years I just deleted the T4A and entered the income as income under self-employment, without the T4A. However, I always worry this will get flagged by the CRA, since the T4A exists in their system based on the company who issued it. Any help would be much appreciated.
