Corporation Tax
(Including Groups, Consortiums, and Loan Relationship Issues)
Helping Companies Manage Corporation Tax with Greater Clarity
Corporation tax remains one of the most important areas of planning for UK companies. From group relief to consortium structures and loan relationship rules, getting it right requires careful planning and technical understanding. At My Tax Consultants, we support businesses with clear, tailored advice—backed by experience in UK tax law and practical business structuring.
Whether your business stands alone or is part of a wider corporate structure, we can help manage exposure and ensure compliance across group or intercompany arrangements.

Group and Consortium Tax Considerations
Group relief allows certain UK companies under common control to pass losses between them. This can be a useful tool for managing tax liabilities across a corporate group. We assess eligibility and timing, and help structure your operations to make the most of reliefs available.
Consortium arrangements, where several companies own a single trading company, bring a different set of rules. Our team works with clients to address ownership percentages, control conditions, and access to reliefs or exemptions.
Key concerns we often advise on include:
- Group structure reviews for tax efficiency
- Qualifying ownership thresholds for group or consortium relief
- Double tax risks on cross-charges or internal transactions
Handling of de-grouping charges

Loan Relationship Tax Issues
Loan relationship rules deal with the taxation of company finance transactions—including interest, debt write-offs, connected party loans, and more. Misunderstanding these rules can lead to serious tax risks, especially in relation to connected company loans or changes in loan terms.
At My Tax Consultants, we assist in reviewing existing and proposed finance arrangements to:
- Identify where connected party rules apply
- Avoid mismatches in recognition of income or expenses
- Support correct accounting treatment for loan releases or impairments
- Plan interest deductions within the restrictions of the corporate interest restriction rules (CIR)
Our support helps reduce errors and supports compliance when dealing with HMRC queries on loan relationships.

Corporation Tax Planning That Supports Business Objectives
Our approach to corporation tax planning always starts with understanding your commercial goals. This includes reviewing your structure, intercompany transactions, and financial arrangements to offer clear solutions—not just compliance.
We assist clients across a wide range of sectors, from small groups of trading companies to investment holdings and consortium-backed ventures. Where needed, we collaborate with accountants and in-house teams to produce accurate computations, disclosures, and planning advice.

Compliance and Reporting Obligations
Effective corporation tax planning does not stop at identifying reliefs or managing tax risk — it also involves preparing accurate and timely documentation. HMRC places particular scrutiny on the treatment of group tax relief, loan relationships, and transactions between connected companies. A minor reporting error can lead to enquiries, delays, or penalties.
We assist businesses with the preparation and review of:
- Corporation Tax returns (CT600), including group and consortium disclosures
- Loan relationship computations and supporting schedules
- Group tax relief claims and elections
- CT61 returns for withholding tax on intra-group interest
- Interest restriction calculations under corporate interest rules
Correctly applying group tax relief allows companies to offset profits and losses across eligible members, reducing the overall corporation tax burden. We work with clients to ensure claims are structured appropriately, elections are submitted within deadlines, and all supporting evidence is in place should HMRC raise queries.
