The election form (T2075) must be filed twice, once with the terminal return and once with the deceased’s TSO. A collections officer will contact the executor about “security acceptable to the Minister”, which will be determined in accordance with the revised policies set out in Information Circular IC98-1R8 (“Tax Collections Policies”).
