the final income tax and benefit return.
 
  If the partner or proprietor died after the end of the business fiscal period, his legal representative can choose to fill in an
optional income tax and benefit return. This means the representative will fill in two sets of returns and two T1139 forms for
the 2023 year:
  A final income tax and benefit return and Form T1139 to report the business income for the regular fiscal period as well as
all other income
  An optional income tax and benefit return and Form T1139 to report the business income from the short fiscal period that is
immediately after the end of the regular fiscal period to the death of the partner or proprietor.
  Final income tax and benefit return for the regular fiscal period and this form
  In this case, the final income tax and benefit return includes the business income from the regular fiscal period and all other
income. The legal representative fills in the financial statements and this form. Fill in the form for the regular fiscal period
