Common questions
What is capital gains tax?
Tax on the profit (gain) when you sell an asset for more than you paid. Most regions apply different rates to short-term vs long-term holdings, and to different asset classes (property vs securities).
Are losses deductible?
Generally yes — capital losses can offset capital gains. Some regions allow carrying unused losses forward; rules vary. Enter a negative gain to model a loss; the calculator will show zero tax due.
What about the principal residence exemption?
Many regions exempt or partially exempt gains on a primary home (e.g., UK PPR, US Section 121 up to $250k single / $500k joint). The calculator does not apply this automatically — exclude home sales unless you've used up your exemption.
How is the cost base calculated?
Original purchase price plus eligible costs (legal fees, stamp duty, renovations for property; commissions for securities). Some regions allow indexation of the cost base for inflation; we use the simple model.
