You must complete this form if you sustained a loss in 2019 and wish to carry it back to one or more of the three previous years. However, you must first apply any loss sustained before 2019 (starting with the loss from the earliest year) to the carry-back years.
You may also use this form to calculate the balance that may be carried forward for a non-capital loss, a net loss with respect to farming or fishing, or a restricted farm loss.
The carry-back of a loss to another year does not reduce any late-filing penalty applicable to the income tax return for the year to which the loss is carried back. However, a refund that results from carrying back a loss to another year may be applied to the payment of any debt you owe to the government under a fiscal law or another law prescribed by the Regulation respecting fiscal administration.
Important: Submit a duly completed and signed copy of this form (either by mail or in person at one of our offices), separately from your income tax return, on or before the filing deadline for the 2019 income tax return.
