Accountants for US and UK: Loans From Your Own Company

A loan from your own UK company is taxed twice over, under two systems that do not speak to each other. HMRC charges the company under CTA 2010 s.455 and the director on an ITEPA s.175 beneficial-loan benefit. The IRS may impute interest under section 7872, trigger a section 956 inclusion, or recharacterise the balance entirely. Both returns must be prepared together.

For a US-citizen owner-director of a UK limited company, the director's loan account is the single most misunderstood line on the balance sheet. UK practice treats it as routine housekeeping: draw against the account through the year, clear it with a dividend before the nine-month deadline, move on. That reflex is correct in the UK and dangerous in the US, because the IRS does not recognise a director's loan account as a category at all. It sees a debit balance owed by a US person to a controlled foreign corporation, and it has at least four separate provisions that can attach to it. Accountants for US and UK returns have to model both outcomes before the money moves, not after. At Jungle Tax we prepare the UK company return, the UK self assessment and the US package as one exercise, precisely because the cheapest UK answer is frequently the most expensive US one.

What actually happens when a US-citizen director borrows from their own UK company?

Strip the jargon away and there are two questions. First, is it a loan at all? Second, if it is, what does each system charge for the use of the money? The UK answers both mechanically, by statute, with thresholds and deadlines. The US answers the first question by looking at substance and the second by imputing a market rate. Where the two answers diverge, you get double taxation, phantom income, or both.

A worked example makes the shape clear. Assume a US-citizen founder resident in London owns 100% of a UK trading company with a 31 March year end. During the year she draws £180,000 against her loan account to fund a property deposit. Nothing is documented. She intends to clear it with a dividend in December.

• UK company: the balance is outstanding more than nine months and one day after 31 March, so a s.455 charge crystallises on the company.
• UK director: the balance exceeds £10,000 all year with no interest paid, so a beneficial-loan benefit arises under ITEPA 2003 s.175, reportable on form P11D with Class 1A National Insurance for the company.
• US individual: the loan is an obligation of a US person held by a CFC. Section 956 is live. Section 7872 imputes interest. And if the documentation is absent, the IRS may simply call the whole £180,000 a distribution or compensation.

Three of those four charges are invisible to a UK-only adviser and two are invisible to a US-only adviser. That is the entire problem.

The UK side: three charges, not one

Section 455: the company's charge

Where a close company makes a loan to a participator, CTA 2010 s.455 imposes a corporation tax charge on the company on the outstanding balance if it is not repaid within nine months and one day of the end of the accounting period. GOV.UK publishes the rate as 33.75% for loans made on or after 6 April 2022; the charge tracks the dividend upper rate, so confirm the rate actually in force for the period you are filing. The charge is not a permanent cost — it is refundable once the loan is repaid, released or written off — but the refund only becomes due nine months and one day after the end of the accounting period in which the repayment happens, and it is claimed separately on form L2P. Cash sits with HMRC in the meantime, often for two years or more.

Two anti-avoidance provisions catch the obvious workaround. Section 464C denies relief where £5,000 or more is repaid and a new loan of £5,000 or more is drawn within 30 days, and section 464A can apply to arrangements where repayment is made as part of a scheme to extract value. Repaying on 28 March and re-drawing on 3 April does not work and has not worked for over a decade.

ITEPA s.175: the director's benefit in kind

Separately, a loan to a director or employee that exceeds £10,000 at any point in the tax year and carries interest below HMRC's official rate produces an employment-related benefit under ITEPA 2003 s.175. The benefit is the difference between interest at the official rate and interest actually paid. GOV.UK records the official rate as 3.75% from 6 April 2025, and since the Autumn Budget 2024 policy change the rate can now be varied in-year, so the rate must be checked rather than assumed. The benefit goes on form P11D (working sheet 4), the company pays Class 1A National Insurance on it, and the director reports it through self assessment.

Note the interaction most people miss: the £10,000 threshold is a cliff edge, not an allowance. Cross it by £1 and the benefit is calculated on the whole balance.

Write-off: the deemed distribution

Writing the loan off looks tidy and is the most expensive exit. The written-off amount is treated as a distribution in the director's hands under ITTOIA 2005 s.415, taxed at dividend rates, and HMRC's long-standing position is that National Insurance is also due where the borrower is a director. The company's s.455 tax becomes reclaimable, but no corporation tax deduction is available for the write-off itself. On the US side a write-off is almost always the trigger that converts a disputed loan into an indisputable distribution or wage — retrospectively, for the year of the write-off, at the full balance.

The US side: four provisions, any of which can bite

Section 7872: imputed interest

IRC section 7872 recharacterises below-market loans. Where a corporation lends to a shareholder at below the applicable federal rate, the foregone interest is treated as transferred from the company to the shareholder — as a dividend if the shareholder is not an employee, as compensation if they are — and then deemed paid straight back to the company as interest income. The rates are the AFRs the IRS publishes monthly. A demand loan, which is what an undocumented director's loan account usually is, is re-measured every year using the blended annual rate; a term loan is tested once at inception and can produce original issue discount consequences over its life.

The de minimis exception for compensation-related and corporation-shareholder loans is $10,000 of aggregate outstanding balance — a threshold most owner-director balances clear on day one, and which does not apply where tax avoidance is a principal purpose.

Section 956: the provision that surprises everyone

This is the one that generalist pages miss entirely, and it is the reason cross-border preparation matters. A CFC that holds "United States property" causes its US shareholders to include the amount in income. Section 956(c)(1)(C) expressly includes an obligation of a United States person within that definition. A loan from your UK company to you, a US citizen, is an obligation of a US person held by a CFC. It is US property. The inclusion is measured on quarterly average balances and capped by the company's earnings and profits.

Corporate US shareholders were largely relieved from this outcome by regulations aligning section 956 with the participation exemption. Individual US shareholders were not. An individual US-citizen owner-director therefore remains fully exposed to a section 956 inclusion on their own director's loan account — a US income inclusion on money they borrowed and still owe, with no UK tax paid on it yet to generate a matching foreign tax credit. That timing mismatch is the single largest avoidable cost we see in this area.

Recharacterisation as compensation or a distribution

Before any of the above, the IRS asks whether a loan exists at all. US case law tests substance over form and the factors are well established: a written note, a fixed maturity date, a stated interest rate at or above the AFR, actual payments of interest and principal, security, the borrower's capacity to repay, the lender's enforcement behaviour, treatment in the books, and whether the pattern of advances tracks profits rather than need. Fail those and the advances become a section 301 distribution — a dividend to the extent of earnings and profits, then return of basis, then capital gain — or, where the borrower works in the business, wages.

The distinction is expensive. A distribution from a UK company may be a qualified dividend eligible for preferential rates, given the US-UK treaty. Recharacterised compensation is ordinary income, potentially outside the foreign earned income exclusion if the year is already at the cap, and it disturbs the company's own corporate tax position on both sides.

Form 5471 and Schedule M

A US person owning 10% or more of a UK limited company files Form 5471. Schedule M requires disclosure of transactions between the CFC and its US shareholder — including amounts loaned and repaid. A director's loan account is a Schedule M item by definition. Omitting it, or filing the 5471 with Schedule M blank while the UK accounts show a six-figure debit balance, is an inconsistency the IRS can and does spot. The base penalty for a late, incomplete or missing Form 5471 starts at $10,000 per form per year, and the statute of limitations for the whole return can stay open while it is outstanding.

US versus UK: the same loan, side by side

Issue	UK / HMRC	US / IRS
Charge on the company	s.455 corporation tax on the outstanding balance if unrepaid after 9 months and 1 day; refundable on repayment	No company-level charge; consequences flow to the shareholder
Charge on the individual	ITEPA s.175 beneficial-loan benefit where balance exceeds £10,000 and interest is below the official rate	s.7872 imputed interest, re-measured annually for demand loans, plus a possible s.956 inclusion
De minimis	£10,000 aggregate balance in the tax year (cliff edge)	$10,000 aggregate for corporation-shareholder loans; no relief where avoidance is a principal purpose
Reference rate	HMRC official rate (3.75% from 6 April 2025; can change in-year)	Applicable federal rate, published monthly; blended annual rate for demand loans
Reporting	CT600A, form P11D working sheet 4, Class 1A NIC, self assessment	Form 5471 Schedule M, Form 1040 Schedule B, Forms 8938 and FinCEN 114 where relevant
If it is not a genuine loan	Deemed distribution on write-off under ITTOIA s.415, plus NIC	s.301 distribution or wages, retrospectively, for the year the advances were made
Reclaim / relief	s.455 tax recoverable via form L2P, 9 months and 1 day after the period of repayment	Foreign tax credit relief only where a matching UK tax actually arises in the same year

What evidence does a genuine loan actually need?

The documentation standard is set by the harsher of the two systems, which is the US. A loan file that satisfies the IRS will satisfy HMRC; the reverse is not true. In practice, we expect to see the following in place before the money leaves the company account:

• A written loan agreement executed by the company and the director, with board minutes approving it and any Companies Act 2006 s.197 member approval where required.
• A fixed maturity date, not "on demand indefinitely". A stated repayment schedule is stronger still.
• A stated interest rate at or above both the HMRC official rate and the relevant AFR for the month of drawdown. Charging the higher of the two removes the UK benefit in kind and the US imputed interest in one move.
• Actual interest payments made and recorded, not accrued and rolled up indefinitely.
• Security where the amount is material, and evidence the director had the capacity to repay at inception.
• Consistent treatment in the statutory accounts, the CT600A, the P11D and the Form 5471 Schedule M. Inconsistency between filings is what triggers enquiry.
• A currency and exchange-rate convention agreed up front, because the US measures the debt in dollars and a falling pound can generate a section 988 foreign currency gain on repayment.

That last point deserves emphasis. A sterling loan repaid by a US person can produce a taxable US exchange gain even where the sterling amount is unchanged. It is a real cost that appears nowhere in UK accounts.

How the two returns are prepared together

Sequencing is everything. The order we work in for an owner-director client with a loan account is deliberate:

• Fix the balance date by date. Rebuild the loan account movement from the ledger, not from the closing balance. The UK needs peak balance and year-end balance; the US needs quarterly averages for section 956 and the full profile for section 7872.
• Test whether it is a loan. Apply the US substance factors first. If it fails, stop treating it as a loan on both returns and price the distribution or compensation outcome instead.
• Model the interest. Compare the HMRC official rate and the AFR for the relevant months. Charging actual interest at the higher rate is usually cheaper than absorbing a benefit in kind plus imputed interest plus the administrative burden of both.
• Model the exit before the accounting reference date. Dividend, bonus, or repayment from personal funds each produce different UK and US results. A dividend clears s.455 and creates a UK dividend charge with a US qualified dividend to match. A bonus creates UK employer NIC and US ordinary income. Repayment from personal funds costs nothing in tax but requires the cash.
• Compute the US inclusions. Section 956, imputed interest, and the year's GILTI/NCTI position interact. A loan reduces the company's cash without reducing its income inclusion, so a founder can face a US inclusion on undistributed profits and a section 956 inclusion on the loan funded by those same profits.
• Align the filings. CT600A, P11D, UK self assessment, Form 5471 with Schedule M, Form 1040, and where relevant Form 8938 and FinCEN 114. The numbers must reconcile across all six.

Our US-UK tax accountants run this as a single engagement because the decision points are shared. Splitting it between a UK accountant and a US preparer who never speak is how the s.956 inclusion goes unnoticed for four years.

How are unfiled or wrongly-reported years corrected?

Most enquiries reach us after the fact: a founder discovers that a loan account running for five years was never reported to the IRS, or that Form 5471 was filed without Schedule M, or that no US return was filed at all. These are fixable, and the route depends on the facts.

Where US returns were never filed

Non-wilful failure is usually corrected through the IRS Streamlined Filing Compliance Procedures. A taxpayer resident outside the US who meets the non-residency test uses the Streamlined Foreign Offshore Procedure: three years of amended or delinquent returns, six years of FBARs, and a signed non-wilfulness certification, with no miscellaneous offshore penalty. A US-resident taxpayer uses the Domestic procedure and pays a 5% penalty on the highest aggregate year-end value of the relevant foreign assets. Our IRS streamlined filing team handles the loan-account reconstruction as part of that package, because the loan balance itself frequently drives the asset values used in the penalty base.

Where returns were filed but the loan was misreported

Amended returns on Form 1040-X with corrected Forms 5471 attached, plus a reasonable-cause statement. Where the only failure is a late or incomplete international information return and there is no unreported income, the delinquent international information return path may apply, with reasonable cause set out in a statement attached to the filing. Detail matters enormously here: a generic "we were unaware" statement is routinely rejected, whereas a chronology showing UK advice received, UK tax paid and the specific point at which the US position was misunderstood is far more persuasive.

On the UK side

Where the s.455 charge was missed, the CT600A is amended within the normal amendment window, or overpayment relief or a discovery correction is used outside it. Where a P11D was never filed, the benefit is reported late with interest and penalties assessed on the Class 1A. Where HMRC's attention is already engaged, the Worldwide Disclosure Facility or a contractual disclosure may be the appropriate route — that is a judgement call made on the facts, not a default.

Critically, the two corrections must be sequenced so the foreign tax credit works. UK tax paid in a corrective filing for an old year credits against US tax for the year to which it relates, not the year it is paid, and the US credit carryback and carryforward periods are finite. Correcting the UK side first, then the US side, with matched years, preserves relief. Doing it in the wrong order, or in different years, wastes it.

Common mistakes we see in this exact fact pattern

• Clearing the loan with a December dividend that lands in a different US tax year from the UK tax year, stranding the foreign tax credit.
• Charging interest at the HMRC official rate only, which removes the UK benefit in kind but leaves the loan below the AFR and still within section 7872.
• Treating the £10,000 UK threshold as covering the US position. It does not; the tests are independent.
• Assuming that because the s.455 tax is refundable, there is no cost. The cash is out of the business for up to two years and there is no US credit for it.
• Filing Form 5471 without Schedule M while the statutory accounts disclose a related-party balance.
• Repaying and re-drawing around the year end, which fails s.464C in the UK and looks like a sham in the US.
• Ignoring the section 988 exchange result on repayment of a sterling loan.
• Writing the loan off to "clean up" the balance sheet, which is the most expensive outcome in both systems simultaneously.

Is a loan ever the right answer?

Yes — but only as a deliberate, documented, interest-bearing arrangement with a defined exit, not as an accumulating overdraft. For a founder with a genuine short-term funding need and the cash to repay inside the accounting period, a properly papered loan at the higher of the official rate and the AFR is clean on both sides: no s.455, no benefit in kind, no imputed interest, and a section 956 exposure limited to the quarterly averages actually outstanding. For a founder using the account as an informal drawings mechanism, it is not a loan and should not be presented as one on either return. That honest assessment, made early, is worth more than any structuring.

Speak to us before the accounting reference date

If you are a US citizen with a debit balance on your director's loan account — whether it is current, historic, or already written off — the position is almost always improvable, and materially so if we see it before the nine-month deadline rather than after. If earlier years were misreported or never filed, the corrective routes are well trodden and the penalty exposure is usually far lower than clients fear. Please contact our cross-border team for a confidential consultation. We will tell you plainly what the loan has cost, what it will cost, and what the cleanest exit looks like on both returns.
