What Is Capital Gains Tax & Who Pays It?

You pay capital gains tax when you sell things like stocks, bonds, or real estate and make a profit. Most people in the US, Canada, and France pay capital gains tax when they sell a house or other property. The amount of tax you owe depends on how you owned the property, how much money you made that year, and which country you live in. A capital gain is when you sell something for more than you paid for it. The difference between what you sold it for and what you paid for it is your profit. This profit is taxable.

If you owned the property for a time, you would pay more tax than if you owned it for a short time. Canada and France have rules, which are explained below. A capital gains tax is a levy imposed on the profit earned from the sale of an asset, such as stocks, real estate, or bonds.
