Capital Gains Tax explained
A capital gain is the difference between what you sell a property for and your adjusted cost base, which is generally what you paid plus eligible costs and improvements. When you dispose of a property that is not your principal residence, that gain may be subject to tax. Under current Canadian rules, half of the gain (the taxable portion) is added to your income for the year and taxed at your marginal rate.
This applies to second homes, cottages, and investment or rental properties. The actual tax depends on your income and tax bracket, since only the taxable half is added to your other income. The 50% inclusion rate and related rules can change, so it is wise to confirm the current treatment before selling.
