Hi,
We cannot advise of the tax implications of a particular transaction that has not actually occurred yet as that would be effectively giving tax advice. You can see guidance on gifts here:
CG12920 - Gifts and Capital Gains Tax: introduction
Unless it is a situation where the no gain/no loss rules apply, which does not appear to be so here, then gifts are treated as taking place at market value and any computations for capital gains on the gift are made on that basis for the disposal value. That disposal value would then be the cost in the hands of the recipient of the gift. The guidance also covers reliefs available where an asset is gifted, including Hold-Over relief. Guidance on hold-over relief can be seen here:
CG66880 - Reliefs: Gifts and Capital Gains Tax: Relief for Gifts of Business Assets
There is also the helpsheet HS295, which includes a link to the claim form, here:
HS295 Relief for gifts and similar transactions (2024)
The guidance below covers what are qualifying business assets:
CG66884 - Relief for Gifts of Business Assets: Qualifying Assets
The criteria are set out for what constitutes a business asset that qualifies for relief under S165 TCGA92 and it is up to you to decide if the asset being gifted meets this criteria according to the particular facts. If the business asset criteria are not met, then relief may be available under the agricultural property rules which may allow relief even where an agricultural property is not used for the trade. Again it would be for you to decide if your asset meets one of the relevant conditions for it to apply.
