Capital gains tax is charged on the gain realised when a chargeable asset is disposed of. The taxable amount is generally the difference between the disposal proceeds and the allowable cost base, adjusted for any permitted reliefs and exemptions. The key concept is that the tax is not charged on the value of the asset itself, but on the profit made on disposal. Disposal usually includes sale, gift, exchange, or certain other events treated as disposals for tax purposes, but the exam-friendly wording is gains arising from the sale or disposal of an asset. Option A is a trap because it implies all assets are taxed and that the tax is on the asset rather than the gain. Option B is incorrect because pensions are typically subject to their own tax rules and CGT is not described as being charged at a reduced rate for pensions. Option C is incorrect in standard exam framing because death is commonly treated as a tax event for inheritance tax considerations, while CGT treatment at death is handled differently depending on regime; the safest syllabus-consistent statement is that CGT is charged on gains on disposal, not simply on transfer on death.
