Why you need to pay extra attention to T5008 slips?

1. For T5008 slip, we add box 21 minus box 20 to your net capital gains on schedule 3;
2. The is based on the fact that all T5008 is prepared correctly. However, we found that many institutions do not prepare T5008 properly, some of them do not filling box 20 with actual costs, some even issue T5008 slips for a purchase transactions and put purchase price into box 21 as proceeds. This kind of practice has made T5008 slips not only useless, but also result in totally wrong capital gains.
3. So unless you know a T5008 slip is correct, don't use it. If already entered, edit or delete it using the numbers from other documents or sources you know are correct.
