Gains and losses on the disposal of shares and securities

Welcome to the World of Shares and Securities!

Hello! If you have ever thought about buying shares in a company like Apple or Disney, you are already thinking like an investor. In the world of UK Taxation, when an individual sells (disposes of) shares, the tax office (HMRC) wants to know if they made a profit. Because shares of the same class in the same company are identical, we can’t just say "I sold the specific piece of paper I bought on Tuesday." Instead, we use special matching rules to figure out the cost of the shares sold. Don’t worry if this seems a bit mathematical at first—we will break it down into easy steps!

1. The Identification Rules (The "Matching" Order)

When an individual sells shares, we have to match the shares sold against purchases in a very specific order. Think of this as a "queue" for which costs we use first.

The Matching Order:
1. Same Day: Match against shares bought on the same day as the sale.
2. Next 30 Days: Match against shares bought in the 30 days after the sale (this is to stop "Bed and Breakfasting," where people sell and quickly buy back just to use their tax allowance).
3. The Section 104 Pool: This is where everything else goes. It is a "pot" containing all shares bought previously.

Did you know? The "30-day rule" exists because, in the past, investors would sell shares on Monday to create a "loss" for tax purposes and buy them back on Tuesday. HMRC caught on and created this rule to stop that trick!

Summary Takeaway: Always look for purchases on the same day first, then look forward 30 days. If there are still shares left to account for, dive into the Section 104 Pool.

2. The Section 104 Pool

The Section 104 Pool is like a big soup pot. Every time you buy shares (that aren't matched by the first two rules), you throw them into the pot. You keep track of two things: the number of shares and the total cost paid for them.

How it works:
When you sell shares from the pool, you calculate the cost using this simple formula:
\( \text{Cost of shares sold} = \text{Total Pool Cost} \times \frac{\text{Number of shares sold}}{\text{Total number of shares in pool}} \)

Example: You have 1,000 shares in your pool that cost you £5,000. You sell 200 shares.
The cost of the 200 shares is: \( £5,000 \times \frac{200}{1,000} = £1,000 \).
Your remaining pool will have 800 shares and a cost of £4,000.

Quick Review Box:
• The Pool treats all shares as if they were bought at the same average price.
• You update the pool every time a new purchase is made (adding shares and cost) or a sale is made (taking them away).

3. Bonus Issues and Rights Issues

Companies often give shareholders more shares. These affect our "Pool" in different ways.

Bonus Issues (Free Shares)

A Bonus Issue is when a company gives you extra shares for free.
The Rule: Add the new shares to the Quantity column in your pool, but add £0 to the Cost column.
Analogy: It’s like a "Buy One Get One Free" offer at the supermarket. You have more items, but your total bank balance hasn't changed!

Rights Issues (Discounted Shares)

A Rights Issue is when the company offers you the "right" to buy more shares, usually at a price lower than the market value.
The Rule: Add the new shares to the Quantity column and add the actual price paid to the Cost column.
Common Mistake: Students often forget that for Capital Gains Tax purposes, the rights issue is treated as if it happened at the time the original shares were bought. In your pool calculations, just add them in at the date they occur.

Summary Takeaway: Bonus = More shares, same cost. Rights = More shares, more cost.

4. Reorganisations and Takeovers

Sometimes a company is bought by another company (a takeover). Instead of giving you cash, they might give you shares in the new company. This is called "Paper for Paper."

The Basic Rule: If you only receive shares in the new company, there is no immediate disposal for tax purposes. You don't pay tax yet! Instead, the new shares just "step into the shoes" of the old shares. They take over the old cost.

If you receive Cash and Shares:
The cash part is a disposal and might trigger a tax bill. You would split the original cost between the new shares and the cash received using their market values at the time of the takeover.

Don't worry if this seems tricky: In the TX exam, the most common scenario is a simple share-for-share exchange where you just carry the old cost forward.

5. Final Tips for Success

Common Mistakes to Avoid:
1. Mixing up the dates: Always check the 30 days after the sale before using the Pool.
2. Incidental Costs: Remember that when you buy shares, the purchase price plus any stamp duty or broker fees goes into the Pool cost. When you sell, subtract the selling fees from the proceeds.
3. Gilt-edged Securities: IMPORTANT! "Gilts" (UK Government bonds) are exempt from Capital Gains Tax for individuals. If the exam mentions a gain on "Exchequer Stock" or "Treasury Stock," the gain is usually tax-free!

Memory Aid: S.30.P
S - Same Day
30 - 30 Days After
P - Pool (Section 104)

Keep practicing the pool adjustments! Once you get the hang of the "Quantity" and "Cost" columns, you will find these questions are a great way to pick up easy marks in your exam. You’ve got this!
