Introduction: Why VAT Place of Supply Decides What Your London Consultancy Bills
The VAT place of supply rules decide whether the invoice your London consultancy sends to a client in New York carries 20% UK VAT or none at all. For an American who has built a strategy, finance or technology consultancy in Britain, that single question moves tens of thousands of pounds a year. Furthermore, it shapes your VAT registration position, the costs you can recover and even the figures that flow into your US tax return.
Most guidance on the VAT place of supply is written for British businesses selling abroad. However, American owners face a second layer that those guides ignore entirely. Your company may be a UK limited company reported on Form 5471, a Delaware LLC reported on Form 8858, or a sole trade on Schedule C. Consequently, a VAT error in London rarely stays in London. It distorts the earnings figures on your US filings as well.
How VAT Place of Supply Works for a Consultancy With American Clients
In short, VAT place of supply is the legal test that fixes which country is entitled to tax a service. If the VAT place of supply is the UK, you charge UK VAT. If it is outside the UK, the service falls outside the scope of UK VAT, and the customer's own country decides what happens next. Since the United States has no federal VAT, a correctly invoiced service to a US business usually bears no consumption tax at all.
HMRC sets out the framework in VAT Notice 741A on the place of supply of services, which implements sections 7A and 8 of the Value Added Tax Act 1994. Notably, the notice was last substantially revised in September 2022, so several competitor pages still quote pre-Brexit rules that no longer apply.
Who This Guide Is For
This guide is written for high-net-worth American founders, former investment bankers and partners who now run consultancies from London. It also covers US companies that bill British clients without any UK office. In our experience working with cross-border business owners, these readers rarely lack sophistication. Instead, they lack a single source that joins the UK VAT place of supply rules to their American reporting obligations.
The General Rules: Business Customers Versus Private Clients
The starting point is whether your customer is a business or a private individual. The VAT place of supply rules treat these two groups very differently, and therefore you must classify every client before you raise the first invoice.
B2B Supplies Follow the Customer
For business-to-business services, the VAT place of supply is where the customer belongs. Accordingly, if your London consultancy advises a corporation headquartered in Chicago, the service is supplied in the United States. You issue an invoice without UK VAT, and the service is outside the scope of UK VAT. The American customer then deals with any local tax under its own rules.
This general rule covers the vast majority of consultancy, management, strategy, financial modelling and technology work. Moreover, it applies whether you deliver the work from London, over video calls or on a trip to the client's office in Manhattan. Where you physically perform the work does not matter for the general B2B rule.
B2C Supplies Follow the Supplier, Unless Schedule 4A Applies
For services to private individuals, the default position reverses. The VAT place of supply for a business-to-consumer service is where the supplier belongs, so a London consultancy would normally charge 20% VAT. However, Schedule 4A paragraph 16 of the VAT Act carves out a list of professional services. These include consultancy, the services of lawyers and accountants, engineering, data processing and the provision of information.
When you supply a paragraph 16 service to a private individual who belongs outside the UK, the VAT place of supply moves to where that individual belongs. Therefore, strategic work for a wealthy American family in Connecticut is outside the scope of UK VAT, even though the family is not a business. Since 1 January 2021, this rule applies to private customers in the EU as well as the rest of the world. Nevertheless, the carve-out is not universal. Coaching, some training and hands-on personal services can fall outside paragraph 16 and so remain subject to UK VAT.
Where a Customer "Belongs"
For VAT place of supply purposes, the belonging test in section 9 of the VAT Act looks at establishments, not passports. A business belongs where it has its business establishment, meaning its head office and central management. Alternatively, it may belong where it has a fixed establishment, which requires permanent human and technical resources. If a US corporation receives your service at its London branch, the service is supplied in the UK and you must charge VAT.
Similarly, private individuals belong where they have their usual place of residence. An American client who has lived in Kensington for five years belongs in the UK, whatever their nationality. As a result, the most common trap for American-owned consultancies is assuming that a US citizen client is automatically an overseas customer.
Proving Your US Client Is a Business
The general B2B VAT place of supply rule only works if you can prove your customer is in business. For EU customers, a VAT number usually settles the point. American customers, however, have no VAT number, so you need other evidence.
Evidence HMRC Accepts for American Customers
HMRC accepts commercial evidence that a non-UK customer is carrying on a business. In practice, that means a signed engagement letter on corporate letterhead, the client's registered company details, an Employer Identification Number, a live company website and correspondence showing genuine trading. For larger clients, a certificate from the IRS confirming business status adds weight, although it is rarely essential.
Importantly, the burden of proving the VAT place of supply sits with you, not with the client. If HMRC challenges the treatment on inspection and your file holds nothing but an email address, it can assess 20% VAT on the full fee. Therefore, build the evidence into your client onboarding process rather than reconstructing it years later.
Invoices, Wording and Record Keeping
An invoice for an outside-scope service should show no UK VAT and state why. Many consultancies add a short note that the service is outside the scope of UK VAT under the VAT place of supply rules. Furthermore, keep the customer's address, business status evidence and contract with each invoice. HMRC can normally assess four years back, six years where you were careless and twenty years for deliberate behaviour, so your records must last at least that long.
For private clients relying on Schedule 4A paragraph 16, the evidence changes. You need proof of where the individual usually lives, such as a US home address, passport details and correspondence. Thus, a client who splits their time between Palm Beach and Chelsea needs careful review before you treat the work as outside the scope.
Exceptions That Override the General Rule
Several special rules override the general VAT place of supply tests. They catch American consultancies more often than any other area, because the work looks like ordinary consultancy on the surface.
Land-Related Services and London Property
Under the land exception, the VAT place of supply for services that relate directly to a specific piece of land is where the land is located. This rule applies regardless of where the supplier or customer belongs. Consequently, if you advise a US private equity fund on the development strategy for one named London office building, HMRC may treat your fee as land-related and subject to UK VAT. General market research on the London property sector, by contrast, is not tied to specific land and follows the general rule.
This distinction matters for real estate consultancies, project managers and surveyors. In particular, a US investor buying a named asset in Mayfair receives a UK-taxable service even though it belongs in Texas. Therefore, examine every property engagement against section 7 of Notice 741A before you invoice.
Events, Training and Use-and-Enjoyment
For admission to conferences, seminars and training events, the VAT place of supply is where the event takes place, even for business customers. Accordingly, if your consultancy sells tickets to a London investor summit to US delegates, you charge UK VAT on those tickets. Bespoke in-house training for a single corporate client, however, normally follows the general B2B rule.
Use-and-enjoyment provisions add a further layer. They apply to hiring out goods, telecommunications, certain electronic services and a few other categories. Where the service would be supplied in one place but is used and enjoyed somewhere else, the tax follows the place of consumption. For most general consultancy work these provisions do not apply. Nevertheless, a consultancy that hires out equipment or resells software licences should check them carefully.
Registration, Thresholds and the Reverse Charge on Imported Services
The VAT place of supply rules also drive whether you must register at all. Many American owners are surprised by how this works in both directions.
Outside-Scope Income and the £90,000 Threshold
A UK-established business must register when taxable turnover exceeds the VAT registration threshold of £90,000, which applies from 1 April 2024. Crucially, outside-scope fees from US clients do not count towards that figure. A consultancy billing £2 million a year exclusively to American corporations could, in principle, stay below the threshold.
Even so, voluntary registration is often worthwhile. Under section 26(2)(b) of the VAT Act, you can recover input VAT on costs linked to supplies made outside the UK, provided those supplies would be taxable if made in Britain. Therefore, a registered consultancy with only US clients can reclaim VAT on office rent, legal fees and technology, while charging no VAT on its sales. VAT Notice 700/1 on who should register explains the voluntary route.
Reverse Charge on American Software and Subcontractors
The rules also work in reverse. When your UK business buys services from an American supplier, the VAT place of supply is usually the UK, because you are the business customer. You then account for VAT yourself under the reverse charge in section 8 of the VAT Act. You declare output VAT on the purchase and, if fully taxable, reclaim the same amount as input VAT.
For a fully taxable consultancy, the reverse charge has no net cost. However, it still has two practical effects. First, reverse-charged services count towards your registration threshold, so a small UK consultancy spending heavily on US software and subcontractors can be pulled into registration. Second, omitting the reverse charge from your returns is an inaccuracy, even when the net effect is nil.
The US LLC With No UK Establishment
A US company or LLC with no establishment in Britain is a non-established taxable person. HMRC's VAT registration manual on non-established taxable persons confirms that no threshold applies to such businesses. If the business makes any taxable supply in the UK, it must register within 30 days.
In most cases, a US company advising UK businesses never needs to register, because the British customer accounts for VAT under the reverse charge. By contrast, a US company that supplies services to British private individuals, runs events in London or provides land-related services on UK property faces immediate registration with no threshold at all.
Input Tax Recovery, Errors and Penalties
Getting the VAT place of supply right also determines how much VAT you recover on costs and what happens when something goes wrong.
Recovering VAT on Costs Linked to US Work
As noted above, where the VAT place of supply is outside the UK, costs attributable to that consultancy remain recoverable, because the supplies would be taxable if made in the UK. However, a small number of consultancies also make exempt supplies, such as certain financial intermediation services. Where you make exempt supplies, partial exemption rules restrict your recovery. Accordingly, a consultancy that arranges financing for US clients needs a partial exemption review, not a simple 100% claim.
Correcting Mistakes and the 2025 Penalty Regime
You can correct errors on your next VAT return if the net value is below £10,000, or below 1% of your Box 6 turnover up to a £50,000 ceiling. Larger errors require a separate disclosure to HMRC. Meanwhile, the penalty regime changed from 1 April 2025. HMRC's late payment penalty guidance now charges 3% of the tax outstanding at day 15, plus a further 3% of the amount still unpaid at day 30. From day 31, a second penalty accrues at 10% a year.
Late returns earn penalty points instead. A quarterly filer who reaches four points pays a £200 penalty for each further late return. Furthermore, all VAT-registered businesses must keep digital records and file through compatible software under Making Tax Digital for VAT. The general framework sits in the VAT guide in Notice 700.
How VAT Interacts With Your US Tax Return
This is where American owners need a cross-border view. The UK guidance stops at the VAT return. Your IRS reporting, however, depends on getting the VAT place of supply treatment right first.
Why UK VAT Earns No Foreign Tax Credit
UK VAT is a consumption tax, not an income tax. Consequently, it never qualifies for the foreign tax credit, which IRS Publication 514 limits to foreign income, war profits and excess profits taxes. Irrecoverable VAT on business costs is simply part of the expense, deductible under section 162 as an ordinary business cost.
Equally, whatever the VAT place of supply, output VAT you collect is not your income, because you hold it for HMRC. Recoverable input VAT is not an expense either. We regularly see prior-year US returns that report VAT-inclusive receipts as gross income, which overstates profit by up to 20%. For a sole trader on Schedule C of Form 1040, that error can inflate both income tax and self-employment tax. Our US tax returns for expats service rebuilds these figures from the VAT records.
Form 5471, Form 8858 and the Bank Accounts Behind Them
If you own a UK limited company, you usually file Form 5471 each year. Whatever the VAT place of supply of each fee, the company's income statement on that form must reflect VAT-exclusive revenue and VAT-exclusive costs. A UK company taxed at the 25% main rate of corporation tax can often use the high-tax exclusion, which applies when the effective foreign rate exceeds 18.9%. Therefore, getting the net figures right can mean the difference between no US inclusion and an unexpected one.
A single-member LLC operating in London instead triggers Form 8858, with its income flowing onto your personal return. In both cases, the business bank accounts that receive the fees count towards your FBAR if you own more than 50% of the company. FinCEN's FBAR filing guidance applies to those accounts, and our FBAR and FATCA reporting service covers missed years. For a general overview of how the tax operates, Investopedia's guide to value-added tax is a useful primer.
Case Study: A London Strategy Consultancy With £1.4 Million of Fees
The following illustrative case study draws on the patterns we see most often. Names and details are anonymised.
What Went Wrong
Daniel is an American former investment banker who founded Harbour Strategy Ltd in London in 2022. In the year to March 2026, the company billed £1,400,000. Of that, £900,000 came from US corporations, £350,000 from UK companies and £150,000 from wealthy private clients living in New York and California. The company also paid £48,000 a year for US research platforms and subcontracted analysts.
The previous bookkeeper applied the VAT place of supply rules correctly to the US corporations. However, the bookkeeper charged 20% VAT on the £150,000 of private-client work, adding £30,000 of VAT that was never due. The bookkeeper also ignored the reverse charge on the £48,000 of US services, which should have produced £9,600 of output VAT and £9,600 of matching input VAT. Meanwhile, Daniel had never filed Form 5471, although he had filed Form 1040 each year.
The Repair and the Numbers
We confirmed that, under the VAT place of supply rules, the private-client work was consultancy within Schedule 4A paragraph 16, and that each client usually lived in the United States. The £30,000 overcharge exceeded the correction limit, which was £14,000 based on 1% of Box 6 turnover. Therefore, the company made a separate error disclosure, refunded the clients and recovered the VAT from HMRC. The reverse-charge omission had no net cost, so we corrected it with no penalty exposure beyond a careless-error review.
On the US side, we rebuilt three years of company accounts on a VAT-exclusive basis. This removed £30,000 of phantom revenue from the 2025 figures. With UK corporation tax at 25%, the company qualified for the high-tax exclusion, so Daniel's net US inclusion was nil. We filed three late Forms 5471 with reasonable-cause statements under the delinquent international information return procedures. As a result, Daniel faced no $10,000-per-form penalty and paid no additional US tax. We also filed missed FBARs for the company's two sterling accounts.
How TaxYork Can Help
TaxYork prepares the US and UK compliance that American-owned consultancies need. We review your client base against the VAT place of supply rules, document business-status evidence, and correct past VAT returns where needed. Furthermore, we prepare your Form 1040, Form 5471 or Form 8858, and FBAR filings on figures that match your VAT records exactly.
Our team also handles double tax questions through our tax treaty optimisation service. In addition, we bring missed US returns and missed reporting up to date without drama. Because we prepare both sides, nothing is lost between your London accountant and your US filings.
Conclusion
The VAT place of supply rules are the hidden engine behind every invoice your London consultancy issues. Business clients in the US normally receive invoices without UK VAT. Private clients abroad often do too, provided the work falls within Schedule 4A paragraph 16. However, property, events and branch-level clients can reverse the result. In addition, the reverse charge, registration rules for US companies and the 2025 penalty regime all hinge on the same analysis.
Ultimately, the US side of the VAT place of supply analysis matters just as much. VAT never earns a foreign tax credit, VAT-inclusive figures distort Form 5471 and Schedule C, and company bank accounts feed your FBAR. Therefore, treat VAT and your US filings as a single compliance exercise rather than two separate problems.
