The effect of a group corporate structure for corporation tax purposes

Welcome to the World of Group Tax!

Hello there! Today, we are diving into one of the most practical and interesting areas of Corporation Tax: Groups. In the real world, big companies like Virgin or Disney aren't just one giant company; they are made up of many smaller companies owned by a parent. For tax purposes, the government allows these companies to help each other out.

Think of a corporate group like a family. If one family member is short on cash (a loss) and another has a surplus (a profit), they can share their resources so the family as a whole pays less tax. Don't worry if this seems a bit complex at first—we will break it down step-by-step!

1. What is a Group?

In the eyes of HMRC, not every company connection counts as a "group." There are two main types of groups you need to know for your exam. It’s all about the percentage of ownership.

A. The 75% Loss Relief Group

This group allows companies to share trading losses and other current-year losses. To form a loss group:

• The parent must own at least 75% of the subsidiary's ordinary share capital.
• To include a "grandchild" company, the parent must still have an effective interest of at least 75%.

B. The 75% Capital Gains Group

This group allows companies to move capital assets (like buildings or machinery) between each other without triggering a tax bill. The rules are slightly different here:

• The parent must own at least 75% of the subsidiary.
• However, the parent must also have an effective interest of more than 51% in any "grandchild" companies.

Quick Review: Remember the "75% rule." If you see a 51% or 60% ownership in a question, they are not part of a 75% group, and they cannot share losses this way!

2. Group Loss Relief: Sharing is Caring

When one company in a group makes a loss, it can surrender (give away) that loss to another company in the group that made a profit. This is called Group Relief.

How it Works (The "Lower Of" Rule)

This is the most important calculation rule. The amount of loss that can be moved is the lower of:

1. The Available Loss in the surrendering company (the one who lost money).
2. The Available Profit in the claimant company (the one who made money).

Example: Company A has a loss of £50,000. Company B has a profit of £30,000. The maximum relief they can claim is £30,000 (the lower amount). This wipes out Company B's profit to zero!

What Can Be Shared?

Surrendering Company: Can surrender current year trading losses, property business losses, and excess management expenses.
Claiming Company: Can use the loss against their Total Profits (before qualifying charitable donations).

Common Mistake to Avoid: You cannot carry back group relief. It is only for losses and profits occurring in the same accounting period. If one company has a 12-month period and the other has a 6-month period, you must pro-rata the figures!

3. Capital Gains Groups

In a Gains Group, the members are treated almost like a single entity for capital gains purposes. There are two big benefits:

Benefit 1: No Gain / No Loss Transfers

When Company A sells a building to Company B (both in the same gains group), it is treated as if the sale happened at a price that results in zero profit and zero loss. The tax bill is effectively "paused" until the asset is sold to someone outside the group.

Benefit 2: Reallocating Gains and Losses

If Company A sells an asset to an outsider and makes a gain, but Company B has a capital loss sitting unused, the group can make a joint election. They can pretend Company B made the gain instead, so the loss wipes it out!

Did you know? This election must be made within 2 years of the end of the accounting period in which the disposal took place.

4. Summary of Key Differences

It’s easy to mix these up, so here is a quick comparison:

• Loss Groups: Used for trading losses. Requires 75% direct/indirect ownership.
• Gains Groups: Used for capital assets. Requires 75% direct ownership and a 51% "effective" link.

Key Takeaway: Groups are all about efficiency. By moving losses to where the profits are, or moving gains to where the losses are, the group pays the minimum amount of tax legally required.

5. Final Tips for Success

1. Check the Dates: Always ensure the companies were in the group for the entire period. If a company joined halfway through the year, you can only share profits/losses for the months they were members.
2. Use the "Lower Of" Rule: Don't just move the whole loss. Always check if the claiming company actually has enough profit to cover it.
3. Capital vs. Trading: Remember that capital losses can never be used to wipe out trading profits through group relief. They stay within the capital gains system.

Don't worry if this feels like a lot to remember! Focus on the 75% rule and the "Lower Of" calculation first. Once you master those, the rest will fall into place. You're doing great!
