Find out if your group will need to send a Corporate Interest Restriction return.
Groups deducting more than £2 million a year
Your interest deductions may be restricted if your worldwide group is:
- subject to UK Corporation Tax
- expecting to deduct more than £2 million a year in net tax-interest and other financing costs
Your worldwide group will be able to appoint a reporting company and send a Corporate Interest Restriction return.
A worldwide group consists of the ultimate parent company and any consolidated subsidiaries.
You can find more information about worldwide groups in CFM95310.
Your group’s net tax-interest amount is its tax-interest expense minus tax-interest income.
You can find more information about how to work out your group’s net tax-interest amount in CFM95600.
Groups deducting £2 million or less
You don’t need to take any further action. However, you must keep any documents that show that your group won’t deduct more than £2 million in net tax-interest and other financing costs.
If your group’s interest deductions aren’t restricted in the current year, you can still appoint a reporting company and send an abbreviated return.
Your group can then carry forward unused interest allowance from that year to use in the future. You can only carry forward unused interest allowance from years that your group sent a return.

Corporate Interest Restriction elections can either be made:
- within a full or abbreviated interest restriction return
- outside of an interest restriction return
