A business owner or business partner will be automatically eligible for Incorporation relief and don’t have to claim it. To compute the payable Capital Gains Tax, deduct the gain, made by selling the business, from the market value of shares received. Let’s understand this by an example; a business owner or partner transfers the business in return of shares worth £100,000 and the profit made is £60,000. If the shares are sold later, their cost for computation of Capital gains tax will be £40,000 (£100,000 - £60,000).

In certain cases, the owner / partner might receive shares and cash when transferring the business. It is also possible to get incorporation relief on the proportion of the business exchanged – Capital gains tax is payable on cash. To make it simple to understand, assume the value of the business, when it is transferred, is £100,000. 80% is received in shares and 20% in cash. In this transaction, profit / gain equal £50,000. Hence, 80% of gain from shares i.e. £40,000 (80% * £50,000) can be postponed until the shares are sold but capital gains tax will have to be paid on 20% of cash gain i.e. (20% * £50,000) while filing the next tax return.

The following step will help with the computation of Incorporation relief

Step 1: We sum up all the consideration, i.e. any cash received and the market value of shares

Step 2: Computation of any Capital Gains on declarable assets such as goodwill and property

Step 3: Calculate the gain not liable to Capital Gains Tax:

Gains not liable to Capital gains tax = Gains (computed in Step 2) * Market value of shares / Cash + Market value of shares
The gains not chargeable are fundamentally rolled over.

Step 4: Calculating the deemed cost of new shares:
Deemed cost of new shares = cost of shares – gain not rolled over (step 3)
