Line 253 - Net capital losses of other years
Generally, if you had an allowable capital loss in a year, you have to apply it against your taxable capital gains for that year. If you still have a loss, it becomes part of the computation of your current year net capital loss. You can use a current year net capital loss to reduce your taxable capital gains in any of the three preceding years or in any future year.
