Introduction: What a Director's Loan Account Costs an American Owner
A director's loan account is the most ordinary thing in British owner-managed business, and one of the most dangerous positions an American can hold. Your accountant treats the overdrawn director's loan account as a routine year-end item. Meanwhile the American side of your affairs may already have produced a deemed dividend running into six figures.
The UK consequences are well documented. Britain charges the company under section 455 and taxes cheap borrowing as a benefit. It also blocks the obvious workarounds. Furthermore every British accountancy firm publishes a director's loan account guide.
What almost nobody explains is the American overlay. At TaxYork we regularly meet founders who repaid the loan on time, avoided every UK charge, and still carried an unreported US income inclusion for the year they held it. Consequently the director's loan account bill arrives years later, usually during a sale or a compliance review.
How a Director's Loan Account Arises
Rarely does anyone decide to borrow. Instead a director's loan account accumulates quietly. A personal expense on the company card, drawings ahead of a dividend, or a property deposit taken while profits form will each do it. Therefore the account becomes overdrawn without any formal decision to lend.
Britain calls you a participator and treats the company as having advanced money to its owner. Accordingly the rules engage automatically, regardless of intention.
Who Is Most Exposed
Sole owners face the sharpest version of the director's loan account problem. A wholly owned UK company is a controlled foreign corporation for American purposes. Additionally, founders drawing against future profits and consultants using a personal company both run these balances routinely.
Exposure scales with the balance and how long it stays outstanding. Notably, a director's loan account repaid within the UK deadline can still produce an American charge. Most guides miss that point entirely.
The UK Charge: Section 455 and the Nine-Month Clock
Start with the British mechanics, because the American analysis builds on them. Section 455 of the Corporation Tax Act 2010 applies whenever a close company lends to a participator. An overdrawn director's loan account is exactly that.
The 35.75% Rate Nobody Has Updated
The rate tracks the dividend upper rate, and it rose this year. HMRC's guidance at CTM61505 confirms that loans made on or after 6 April 2022 carried 33.75 per cent. The rate is 35.75 per cent from 6 April 2026.
Check any director's loan account figure you read elsewhere. HMRC's own public page on director's loans still quotes 33.75 per cent, and virtually every accountancy blog repeats it. Therefore a 2026 loan costs two percentage points more than most sources will tell you.
The Nine-Month Deadline and Form CT600A
No charge arises if the director's loan account clears within nine months and one day of the corporation tax period end. The company reports the position on form CT600A with its return.
Miss that date and the company pays. Importantly the charge falls on the company, not on you personally. That distinction matters enormously for the credit analysis later.
Reclaiming the Charge Under Section 458
The charge is refundable rather than permanent. Once you repay, release or write off the loan, section 458 allows the company to reclaim it.
Patience is required though. The refund is not due until nine months after the end of the accounting period in which repayment occurs, so the money can sit with HMRC for the better part of two years. Moreover HMRC repays the tax but not interest.
The Anti-Avoidance Rules That Catch Repayment
Britain anticipated the obvious response, which is to repay just before the deadline and re-borrow immediately afterwards. Two rules block it, and their thresholds differ.
The Thirty-Day Rule and the £5,000 Threshold
Suppose the loan exceeded £5,000 and you redraw £5,000 or more within thirty days either side of repaying. HMRC then charges section 455 on the original amount anyway. The repayment is simply ignored for these purposes.
Consequently a December repayment funded by a January redraw achieves nothing. Furthermore the rule looks at substance, not labels.
The £15,000 Arrangements Rule
A second and wider rule applies above £15,000. Under section 464C, the charge stands regardless of the thirty-day window where arrangements or an intention to redraw existed at repayment.
No bright line protects you here. Therefore document a genuine commercial reason for clearing the director's loan account, particularly where the balance recurs.
The Benefit in Kind Above £10,000
Separately, a director's loan account exceeding £10,000 at any point in the tax year creates an employment benefit unless you pay interest at the official rate. HMRC's small loans exemption sets that threshold, and the official rate of interest stands at 3.75 per cent for 2026/27 under the published beneficial loan rates.
The benefit is reportable and attracts employer Class 1A national insurance. Additionally it is genuine employment income for you, which does at least generate UK tax capable of supporting a credit.
The US Side Everyone Gets Wrong
Here the analysis diverges sharply from what most advisers assume, and the error runs in both directions.
Why Section 7872 Usually Does Not Apply
American practitioners reach instinctively for the below-market rules in section 7872, which impute interest on cheap shareholder loans. That instinct is generally wrong here.
The temporary regulations exempt loans where the lender is a foreign person and the borrower is a United States person. An exception applies where the imputed interest would be effectively connected with a US trade or business. Your British company is a foreign lender, so the exemption ordinarily applies. Accordingly imputed interest is rarely the problem.
Section 956: The Real Exposure
The genuine danger sits elsewhere. Section 956 treats a controlled foreign corporation's investment in United States property as a deemed distribution. Its US shareholders take the inclusion. Critically, an obligation of a United States person counts as United States property.
Your overdrawn director's loan account is itself an obligation of a United States person. Therefore your company has invested in US property by funding your director's loan account. You take an income inclusion measured by the loan and capped by the company's applicable earnings. This happens whether or not cash reaches America, and whether or not you repay inside the UK nine-month window.
Why Individuals Fare Worse Than Companies
Corporate American shareholders largely escaped this after 2017. Regulations aligned section 956 with the participation exemption for dividends received. Individuals got no such relief.
Consequently an individual owner takes the full inclusion at ordinary rates reaching 37 per cent. The asymmetry falls precisely on the founder-owner profile that dominates British small companies, and a director's loan account is how it usually arises.
Bona Fide Loan or Constructive Dividend
Even setting section 956 aside, a second American risk applies. If the arrangement is not a real loan, the IRS can simply treat the money as a distribution.
What Makes a Loan Real
Substance governs. Look for a written agreement, a stated interest rate and a fixed repayment date. Actual repayments, security where appropriate and a realistic ability to repay all reinforce the position.
Where those features are missing, the director's loan account looks like earnings extraction wearing a loan label. Consequently the IRS characterises it as a dividend, and no repayment later undoes that.
Documentation That Survives Scrutiny
Board minutes recording the decision carry real weight, as does charging interest at a commercial rate rather than at nil. Furthermore consistency matters. A director's loan account that swings overdrawn yearly and clears only at the deadline invites the argument that nobody intended a loan.
Why the Section 455 Charge Earns You No Credit
This is the asymmetry that makes the position genuinely expensive rather than merely complicated.
The Company Pays and You Cannot Credit It
Section 455 is corporation tax. Your company pays it, so it is not your foreign tax. An individual may credit only tax imposed on that individual. Therefore the £143,000 your company hands HMRC does nothing to reduce your American charge on the same director's loan account.
Only the benefit-in-kind charge produces personal UK tax, and that is calculated on notional interest rather than on the loan itself. Consequently the amounts never match.
Refundable Taxes Fail the Test Anyway
A creditable tax must be a genuine, non-refundable liability. Section 455 is designed to return to the company once the loan clears. That refundability independently undermines any argument for crediting it.
Understanding where your credits actually sit becomes essential in this situation, which is why we set out how Americans in Britain stop wasting UK tax paid separately.
Case Study: A £400,000 Balance
An American founder owns her London consultancy outright, making it a controlled foreign corporation. During the year to 31 March 2027 her director's loan account reached £400,000. It funded a property purchase while she left profits in the company.
The UK Position
She did not clear the balance by 1 January 2028. Her company therefore paid section 455 at 35.75 per cent, which came to £143,000, recoverable only years later.
The benefit in kind added more. At the official rate of 3.75 per cent the notional interest came to £15,000, taxed on her at 45 per cent. Employer Class 1A national insurance fell on the company on top.
The US Consequence
Her previous adviser reported nothing to the IRS, reasoning that a director's loan account is not income. Section 956 says otherwise. The company held ample earnings, so the inclusion equalled the loan, roughly $528,000 at the rates then prevailing.
At 37 per cent that produced about $195,000 of American tax. Furthermore no meaningful credit was available. The £143,000 was her company's tax, and her only personal UK tax was the £6,750 on notional interest.
The Fix
We cleared the director's loan account before the following year end using a properly documented dividend. That carried real UK tax on her personally and therefore supported a credit. Additionally we charged interest at a commercial rate on the remaining drawings to protect bona fide loan status.
Timing did the heavy lifting. Had she taken the dividend route from the outset, the same cash would have reached her carrying a creditable UK charge rather than an uncreditable American one.
Reporting and Fixing Earlier Years
The loan is not merely a computational matter. It drives disclosure, and omissions here carry their own penalties.
Which Forms Capture the Loan
An American owning a UK company generally files Form 5471. The director's loan account appears in the intercompany balances and drives the section 956 computation. Where the structure involves a disregarded entity, Form 8858 applies instead. We cover its Schedule M treatment of these balances in our guide to the return almost everyone misses.
Whether your company is disregarded or treated as a corporation changes the answer completely. Our note on when a UK limited company is disregarded explains the election and its consequences.
Correcting Past Years
Unreported section 956 inclusions are fixable. Where the failure was non-wilful, the IRS Streamlined Filing Compliance Procedures remain the standard route. Our IRS Streamlined Filing service handles the full package. Alternatively an amended return may suffice where the rest of the filing was sound.
Related payroll and reporting duties often surface at the same time, as our guide for US citizens serving as UK company directors sets out.
How TaxYork Can Help
We prepare US and UK returns for wealthy Americans running British companies. Director's loan account work sits at the centre of that. Specifically, we compute the section 956 exposure before your year end rather than after it. Furthermore we test bona fide loan status and document it properly. We then model whether a dividend, salary or repayment produces the better combined outcome.
Where the UK and US charges genuinely conflict, we escalate. Our cross-border planning service and US tax return preparation work together throughout. Occasionally a genuine treaty conflict warrants a competent authority request.
Conclusion
A director's loan account is not a neutral bookkeeping entry once an American owns the company. Three points carry most of the value. The UK charge rose to 35.75 per cent on 6 April 2026, and almost every published source still says 33.75. Section 956 turns the director's loan account into a deemed dividend for you personally, even where the UK rules are satisfied in full. Above all, the section 455 charge is your company's tax, so it cannot shelter your American liability.
Timing and documentation remain the levers. Professional bodies including the Chartered Institute of Taxation and ICAEW publish helpful UK background, though neither addresses the American overlay. Ultimately a director's loan account rewards owners who plan the extraction before the money moves, and punishes those who reconcile the account afterwards.
