Calculating the capital gains deferral
The capital gains deferral is available for the disposition of eligible small business corporation shares made in 2018. The investment can be made by an individual in any particular corporation (or related group).
The permitted deferral of the capital gain from the disposition of eligible small business corporation shares is determined by the following formula:
Capital gains deferral = B x (D ÷ E)
B = the total capital gain from the original sale
E = the proceeds of disposition
D = the lesser of E and the total cost of all replacement shares
For dispositions in 2018, report the total capital gain on lines 131 and 132 of Schedule 3 and the capital gains deferral on line 161 of Schedule 3. The capital gain you must report in the year of disposition will be determined by subtracting the capital gain deferral from the total capital gain realized from the disposition.
Deferred capital gains do not qualify for the capital gains deduction (line 254). Therefore, do not report on lines 106 and 107 of Schedule 3 any disposition of qualified small business corporation shares if you elect to defer the capital gains that resulted from the disposition of those shares. Instead, report such disposition on lines 131 and 132 of Schedule 3.
Adjusted cost base (ACB) reduction
You must use the capital gains deferral to reduce the ACB of each of the eligible replacement shares by the amount determined by the following formula:
ACB reduction = F x (G ÷ H)
F = capital gains deferral
G = the cost of replacement shares
H = the total cost of all the replacement shares
Completing your schedule 3
Report capital gains deferral on line 161 of Schedule 3.
If you elect to defer the capital gains that resulted from the disposition of qualified small business corporation shares, report such disposition on lines 131 and 132 of Schedule 3.
