Group Relief Ireland: How Companies Use Losses Across a Group
It is common for one company in a group to make a profit while another makes a loss.
Without planning, the profitable company may pay corporation tax while the loss-making company cannot fully use its losses.
However, Irish tax rules allow groups to use losses more efficiently. This is done through group relief.
In this guide, we explain how group relief works in Ireland, when companies qualify, and how businesses can use it to improve tax efficiency.
What Is Group Relief?
Group relief allows one company to surrender losses to another company within the same group.
As a result, the receiving company can use those losses to reduce its taxable profits.
In practice, this means:
- A loss in one company can reduce tax in another
- The group can optimise its overall tax position
Therefore, group relief ensures that profits and losses are considered at a group level rather than company by company.
When Do Companies Qualify as a Group?
Not all companies can use group relief.
For corporation tax purposes, a group generally exists where:
- One company owns at least 75% of another company, or
- Both companies are 75% subsidiaries of a third company
In addition, the parent company must have:
- Entitlement to at least 75% of profits available for distribution
- Entitlement to at least 75% of assets on a winding up
These conditions ensure that the group structure reflects genuine economic ownership.
How Group Relief Works (Simple Example)
Consider the following scenario:
- Company A makes a loss of €100,000
- Company B makes a profit of €150,000
Without group relief:
- Company B pays corporation tax on €150,000
With group relief:
- Company A surrenders €100,000 loss to Company B
- Company B is taxed on €50,000 instead
As a result, the group reduces its overall tax liability.
What Losses Can Be Surrendered?
Not all losses qualify for group relief.
However, common examples include:
- Trading losses
- Certain charges on income
- Excess capital allowances
- Management expenses (in some cases)
These losses must generally arise in the same accounting period as the profits they are offset against.
Key Conditions and Restrictions
Although group relief is flexible, several conditions apply.
Same Accounting Period
Losses must generally relate to the same accounting period, or a corresponding accounting period where applicable.
Within the Charge to Irish Tax
Companies must be within the charge to Irish corporation tax.
In practice, this usually includes:
- Irish resident companies, or
- Irish branches of foreign companies
Ownership Requirements
The 75% ownership test must be met throughout the relevant period.
If ownership changes during the year, this can affect the availability of group relief.
Cross-Border Limitations
In general, losses from non-Irish companies cannot be used in Ireland.
However, limited exceptions may apply in specific circumstances.
Claims and Compliance
Group relief must be claimed within the required time limits and supported by appropriate documentation.
Why Group Relief Matters
Group relief is not just a technical rule. It has practical benefits.
For example, it can:
- Reduce overall corporation tax paid by a group
- Improve cash flow by lowering tax payments
- Allow better use of losses across multiple companies
- Prevent losses from sitting unused in one entity
As a result, it plays an important role in group tax planning.
Common Mistakes Businesses Make
In practice, many groups:
- Do not review group structures for eligibility
- Miss deadlines for making claims
- Fail to align accounting periods
- Leave losses unused in one company
- Do not coordinate tax planning across the group
However, most of these issues can be avoided with proper planning.
How This Links to Corporation Tax Losses
Group relief forms part of the wider corporation tax loss rules in Ireland.
While companies can:
- Carry losses back
- Carry losses forward
They can also use losses across group companies where conditions are met.

Final Thoughts
Group relief allows companies to use losses more efficiently across a group.
When applied correctly, it can:
- Reduce tax liabilities
- Improve cash flow

However, the rules require careful planning and correct implementation.
