Do you plan on selling your principal residence?

As long as it has been your principal residence for every year that you have owned the property, you will not have to pay any tax on any gain from the sale. If it was not your principal residence at any time you have owned the property, or only part of the property is considered your principal residence, you will have to pay part of the tax on the capital gain. This corresponds to the years it wasn’t your principal residence or the square feet that were not included as part of the principal residence.
