Share identification rules (UK individuals)
For an individual’s UK capital gains calculation, shares of the same class in the same company are generally matched first with same-day acquisitions, then with qualifying acquisitions in the following 30 days, then with the Section 104 pool. The 30-day rule has a UK-residence condition and other detailed rules can apply. Pool costs are aggregated and allocated to matched shares under the applicable law. Company share-identification rules differ; check the assessment period and facts.
Worked example
An eligible UK-resident individual sells 100 shares, acquires 20 of the same class on the sale day and 30 within the following 30 days, and has sufficient shares in the Section 104 pool. The disposal matches 20, then 30, then 50 shares respectively, subject to all applicable conditions.
Common mistake
Using the Section 104 pool before same-day and qualifying 30-day acquisitions, or applying the individual order automatically to a company.
