Loans to Participators: The ‘Upstream Loans’ Dilemma
The ‘loans to participators’ regime was designed to prevent company directors and shareholders from extracting funds in the form of loans rather than salary or dividends, which would otherwise be subject to income tax and National Insurance. Under CTA 2010, s 455, loans made by close companies (typically owner-managed businesses) to their participators (shareholders or their associates) trigger a temporary corporation tax charge of 33.75% if the loan remains outstanding nine months after the end of the accounting period.
This tax is refundable once the loan is repaid, but the repayment is delayed by at least nine months after the period in which repayment occurs.
However, section 455 legislation can create unintended tax burdens, particularly in the case of management buyouts (MBOs) and corporate reorganisations, where the company’s own funds are used to finance the acquisition of shares.
How Does the Loans to Participators Rule Work?
The loans to participators rule applies when:
- A close company makes a loan to a participator (usually a shareholder or their associate).
- The loan is not repaid within nine months of the company’s year-end.
- A temporary 33.75% corporation tax charge applies until the loan is repaid or formally written off.
A related provision, CTA 2010, s 459, extends the regime to indirect loans, meaning that a company may still be taxed even if it does not lend directly to a participator but does so through a connected arrangement.
This provision causes particular problems for management buyouts and corporate reorganisations.
The ‘Upstream Loans’ Issue in a Management Buyout (MBO)
In a typical management buyout, senior managers acquire a company from its existing owners. Since they rarely have the personal funds to purchase the shares outright, they usually set up a new company (BidCo) to acquire the existing company (TargetCo).
How an MBO is Structured
- Managers create BidCo, which is used to acquire TargetCo.
- BidCo borrows money or secures funding to buy out the existing shareholders.
- TargetCo’s cash is often used to help repay BidCo’s acquisition debt.
- This cash movement from TargetCo to BidCo is referred to as an “upstream loan.”
While a dividend from TargetCo to BidCo would normally be tax-free under CTA 2009, s 931A, a loan from TargetCo to BidCo triggers CTA 2010, s 459, if the funds are then used to repay the original shareholders.
Why Upstream Loans Create a Tax Risk
The problem arises when TargetCo loans money to BidCo, which then pays off the old shareholders. Since those shareholders were participators in TargetCo, but are now loan creditors in BidCo. The transaction falls under CTA 2010, s 459, which applies to indirect loans.
This means:
- A 33.75% corporation tax charge can apply to TargetCo if HMRC determines that its funds have been used to indirectly benefit its former participators.
- The tax remains payable until BidCo repays the loan to TargetCo.
Example: How an Upstream Loan Triggers a Tax Charge
- Two managers (M1 and M2) create BidCo to buy TargetCo.
- BidCo buys the shares from the three existing shareholders (S1, S2, and S3).
- BidCo borrows cash from TargetCo to pay for the purchase.
- Since S1, S2, and S3 were participators in TargetCo and are now creditors in BidCo, HMRC considers this an indirect loan under section 459.
- TargetCo is now liable for a 33.75% corporation tax charge on the loan unless it is repaid within nine months.
HMRC’s View on Indirect Loans
HMRC has taken a strict stance on upstream loans. In the Company Taxation Manual (CTM61550), HMRC states:
“This is exactly the type of arrangement which should be chargeable… the company’s own money is being used to buy out the existing shareholders.”
This suggests that HMRC sees upstream loans as a form of disguised distribution rather than a legitimate financing mechanism for MBOs.
The Chartered Institute of Taxation (CIOT) has raised concerns and sought clarification from HMRC, but as of now, no formal guidance has been issued on when section 459 should apply in these cases.
Mitigating the Tax Risk on Upstream Loans
To avoid or reduce the risk of a section 455 or section 459 tax charge, companies considering an MBO or corporate restructuring should consider the following strategies:
1. Seek HMRC Clearance Before the Transaction
Companies can request informal clearance from HMRC as part of a pre-transaction clearance procedure. This provides certainty on whether section 459 will apply.
2. Use Distributable Reserves to Fund Dividends Instead of Loans
If TargetCo has sufficient distributable reserves, it can pay a dividend to BidCo instead of making a loan. A dividend received by BidCo would typically be tax-free, avoiding the section 459 charge.
3. Repay the Loan Quickly to Avoid the Nine-Month Rule
If an upstream loan is necessary, structuring the deal so that BidCo repays the loan within nine months can prevent the tax charge from arising.
4. Structure the MBO with External Debt Instead of Internal Loans
If BidCo finances the acquisition with third-party bank loans rather than using TargetCo’s cash. The risk of an indirect loan charge is eliminated.
Conclusion
The loans to participators regime, designed to prevent tax avoidance through shareholder loans, is creating unintended complications for legitimate company transactions, particularly management buyouts and corporate reorganisations.
HMRC has indicated that section 459 will apply to upstream loans, making it essential for companies to plan carefully.
Key Takeaways for Businesses and Advisers:
- Ensure transactions do not involve indirect loans from subsidiaries to holding companies.
- Where possible, use dividends rather than loans to move funds.
- Seek clearance from HMRC to clarify tax treatment before completing a transaction.
- If a loan is unavoidable, ensure it is repaid within nine months.
- Consider alternative financing options, such as external borrowing.
For businesses considering an MBO or restructuring, professional tax advice is essential to avoid unexpected tax liabilities under the loans to participators rules.
