Mark (51 years old) works full-time for a Canadian scientic undenivater research and development corporation (his employer) located in Kingston. Ontario. Mark has worked for this corporation out of the Kingston ofce for nine years. Mark earned a net income for tax purposes of $85,000 in 2020.

She earned a net income for tax purposes of $3.525 in 2020. All of the children are in good health and none of them have income of their own. Mark and Carice came up to you to discuss the following tax matters: 1. Mark and Carice and their three children returned to Canada in February of 2021 following ten- subsequent months sailing trip in the Gulf of Mexico and Caribbean Sea where Mark was performing scientic research for his employer. Since the family only resided in Canada for the rst four months of 2020 (121 days), Mark and Carice are wondering to know their residency status in 2020. Mark said \"Does the fact that we were only in Canada for 121 days in 2020 altect our residency status?\" 2. Mark said "in addition to our family home located in Kingston, Ontario. we, as a couple, own a cottage located in Muskoka District Municipality, Ontario, which we usually visit in the summer. We are consrdering sailing both real estate properties next year (2021) and moving to USA". The cottage cost $320,000 and has a current market value of $520,000. Their family home originally cost $300,000 and is now valued at $600000. The couple has owned the cottage for five years and the home for ten years. Carice said \"i heart that if a property qualities as a principal residence, we can use the principal residence exemption to reduce or eliminate any capital gain otherwise occurring, for income tax purposes, on the disposition of the property 80, if we sell our home and cottage, how do we know which one (home or cottage) is the principal residence?\". Mark raised his hand and said \"How we could calculate the number of years that each property would be designated as the principal residence if we were to sell both homes this year\". 3. Carice said: \"Let's suppose that i would stay in Canada this year and years alter and l have a plan to establish a sole proprietorshrp of an unincorporated business that would sell secun'ty related products to both retail customers and to building contractors". If the business requires to get works services from third parties, Carice asked \"Could you please briey explain the cons and pros of hiring independent contractors, as opposed to hiring employees to get the required senrrces". 4. Mark had a question about his 2020 income tax return: "Assume that Carice and i are required to le 2020 income tax returns, how much the maximum amount of 2020 tax credits that can be applied against my federal Tax Payable. Could you please show me the calculation?". 5. Carice told you that she had a discussion with her friends last month and they struggled with many tax issues and she want you to conrm or correct their thought with yourjustication. These are the statements they have concluded: (a) \"Canadian citizens living outside Canada have to file a Canadian tax retum".
