Each reserve is deducted in computing the gain or profit. It is then added back in the next year, and a further may be claimed if proceeds are still owing at the end of that next year, subject to the limits described below.
Capital gains reserve
The maximum amount you can claim in a year is limited to the lesser of two amounts:
- a “reasonable reserve”, which is usually the amount equal to (gain x proceeds due after the year / total proceeds); and
- a fraction amount, which varies depending on the year.
The fraction amount is: 4/5ths for the year of disposition, 3/5ths for the following year, 2/5 for the year following that, and 1/5 for the year after that. So the reserve can be claimed only for 4 years, which means that the gain may be spread out for a maximum of 5 years.
