Capital Gains Tax 08 - When you cannot use a worksheet

The worksheet is for simple calculations of gains or losses and can be used for the disposal of land or other assets. You can also use it for the disposal of shares but only if it is the disposal of the whole of your holding of a particular class of shares.

You will not be able to use the worksheet in all cases. For example:

You should also not use the worksheet if you have to pay Capital Gains Tax on gains made by a non-UK resident Trust or a non-UK resident company in which you have an interest, or on gains which arose in earlier years but became taxable in 2020 to 2021.
