A UK limited company with no US presence generally has no Form 1099-NEC duty. What does bite: worker classification, W-9 records, permanent establishment, VAT reverse charge and corporation tax.
A UK limited company with no US entity, branch or permanent establishment generally does not have to issue Form 1099-NEC to a contractor in the United States. The US information-return rules attach to a payer making payments in the course of a trade or business, and the IRS states plainly that "you are not required to file information return(s) if ... you are not engaged in a trade or business." What does bite a UK payer is worker classification, evidence of who was paid, and — if the work touches the UK — payroll, VAT and corporation tax.
This is the mirror image of a case we cover separately — a UK freelancer invoicing American clients and completing a W-8BEN.
The Instructions for Forms 1099-MISC and 1099-NEC require a filing "for each person in the course of your business during the year to whom you have paid at least $2,000" in nonemployee compensation. The IRS's summary page frames it the same way — "If, as part of your trade or business, you made any of the following types of payments..." — and, on the other side: "You are not required to file information return(s) if any of the following situations apply: You are not engaged in a trade or business."
So the question is not "is my contractor American?" but "am I, the payer, engaged in a trade or business for these purposes?" For US information-reporting that means a US trade or business — and a UK company selling to UK customers, managed and staffed in the UK, is not carrying one on because a supplier lives in Denver.
There is no single statutory definition; it is a facts-and-circumstances test resting on whether the company carries on regular, continuous and substantial activity in the United States, usually through people or a place. Indicators include US-based employees or dependent agents who habitually conclude contracts for you, a US office or workshop, a registered branch or subsidiary, and regular US-located selling activity. If in doubt, get this looked at before the first invoice.
Where a 1099-NEC obligation does exist, the reporting threshold for nonemployee compensation increased to $2,000 for tax years beginning after 2025, and the form must be filed "on or before January 31". Payments to a corporation — including an LLC treated as a C or S corporation — are generally exempt, with legal services a notable exception.
The cleanest trigger. If you incorporate a US subsidiary or register a US branch, and that operation engages and pays the contractor, you have a US payer paying in the course of a US trade or business: W-9 in, 1099-NEC out, an EIN to file under, and state obligations on top.
The treaty defines a permanent establishment in Article 5(1) as "a fixed place of business through which the business of an enterprise is wholly or partly carried on"; Article 5(2) lists a place of management, branch, office, factory and workshop, and Article 5(3) makes a building or installation project a PE "only if it lasts for more than twelve months". Two provisions matter most when hiring:
Article 5(6) protects genuine independent agents; Article 5(7) confirms that controlling or being controlled by a US company does not by itself create a PE. Article 7(1) then does the real work: business profits are taxable only in the residence state "unless the enterprise carries on business in the other Contracting State through a permanent establishment situated therein".
One caution: the treaty governs federal income tax, and US states are not bound by it, so a state may assert taxing rights on its own nexus standard even where no treaty PE exists. See our guide to permanent establishment risk.
Separately from 1099 reporting, the regime for payments to foreign persons can reach a UK company. The IRS defines a withholding agent as "a U.S. or foreign person that has control, receipt, custody, disposal, or payment of any item of income of a foreign person that is subject to withholding" — expressly including foreign corporations. On US-source income paid to a non-US person the default rate is 30%, reported on Forms 1042 and 1042-S.
Sourcing is decisive: "the place, where the personal services are performed, generally determines the source of the personal service income." A payment to a genuine US person for work done in the US is therefore neither 1042-S territory nor, for a UK-only payer, 1099 territory. But if your "US contractor" is a non-resident alien, run the analysis properly.
A UK company can get the paperwork right and still be exposed if the person is, in substance, an employee. The IRS tests common-law control across three categories:
The IRS is explicit that "there is no 'magic' or set number of factors that 'makes' the worker an employee or an independent contractor and no one factor stands alone", and that "the keys are to look at the entire relationship and consider the extent of the right to direct and control the worker." A contractor agreement is one fact among many; it does not decide the question. Where status is genuinely unclear, either party can file Form SS-8 for an IRS determination — which the IRS notes typically takes at least six months. States apply their own, often stricter, tests for wage and hour, unemployment insurance and workers' compensation. Our worker classification guide works through the indicators.
Ask for a Form W-9 (current revision 03/2024) before the first payment. Its purpose is to let a person "provide your correct Taxpayer Identification Number (TIN) to the person who is required to file an information return with the IRS", and it certifies US person status. A UK company that will never file a 1099 should still hold it, because it:
If the form comes back indicating a non-US person, ask for the appropriate Form W-8 and take advice before paying. Backup withholding at 24% applies to a US payer where the payee has not provided a correct TIN — a further reason the W-9 is not optional once you have a US presence.
| Fact pattern | Form 1099-NEC needed? | US withholding? | UK treatment |
|---|---|---|---|
| UK Ltd, no US entity, branch or PE; contractor works in the US | Generally no — payer not in a US trade or business | No | Deductible if wholly and exclusively; reverse charge applies |
| UK Ltd whose US subsidiary engages and pays the contractor | Yes, if $2,000+ | No, for a US person with a W-9 | Intercompany charge and transfer pricing to review |
| UK Ltd paying from a US branch or treaty PE | Yes, if $2,000+ | No, for a US person | Branch profits in UK CT, relief for US tax |
| UK Ltd with US presence paying a US C or S corporation | Generally exempt (legal services an exception) | No | As above |
| Services performed in the US by a non-US person | No — 1042-S instead | 30% default unless treaty-reduced | Check withholding-agent status first |
| US contractor spends part of the year working in the UK | Unchanged | Sourcing splits by days worked | UK employment-tax and off-payroll analysis needed |
UK source. Duties performed physically in the UK can create UK employment or trading income for the individual, depending on their residence and treaty position. Bringing a contractor over for a six-week project is not a neutral act.
Off-payroll working. Where a worker supplies services through their own intermediary, a medium or large client determines employment status, while for a small client "the worker's intermediary is responsible for deciding the worker's employment status." HMRC's manuals confirm a client escapes the rules only if it is "wholly outside the UK" — not UK resident, no UK permanent establishment — which a UK limited company plainly is not. Whether the engagement produces any UK employment-tax liability turns on the worker's residence and where duties are performed. Start with our off-payroll working guide.
UK VAT. The B2B general rule in VAT Notice 741A is that "the supply is made where the customer belongs" — so services bought from a US freelancer by a UK business are supplied in the UK, and the customer accounts for the VAT under the reverse charge, crediting output tax and debiting the input tax it can recover. Crucially, the value of reverse-charge services counts towards the £90,000 VAT registration threshold: a business below it that buys heavily from overseas contractors can be pushed into compulsory registration by its purchases alone.
Contractor fees are deductible in computing trading profits if they satisfy section 54 CTA 2009 — expenditure is not deductible "unless it is incurred wholly and exclusively for the purposes of the trade". Genuine third-party fees clear that easily; mixed-purpose costs do not, and HMRC will not apportion a dual-purpose expense.
On currency, HMRC's manuals state that "the basic rule is that the taxable profits are to be calculated in sterling". Translate each USD invoice at the rate in your accounting records, apply it consistently, and let exchange differences fall out through the accounts. Keep the evidence: statement of work, invoices, payment confirmation, the W-9 and a classification note.
A UK SaaS company with no US entity engages a developer working from home in Texas for nine months at $4,000 a month — $36,000 in total.
Change one fact — he starts signing contracts with US customers in the company's name — and the PE analysis, and potentially US federal and state filings, change with it.
1. Decide status first. Run the three IRS control categories before agreeing terms. If control looks employment-like, price an employment solution instead.
2. Confirm where the work will be performed, and whether any of it happens in the UK. Put the answer in the contract.
3. Request a Form W-9 and check the entity type and TIN. If a Form W-8 comes back, take advice.
4. Issue a statement of work, not a job description: deliverables, milestones, own equipment, genuine substitution rights, no benefits.
5. Check your US footprint annually. Any US office, sales agent or subsidiary changes the reporting answer.
6. Flag the VAT reverse charge to your bookkeeper, and record the exchange rate used for each invoice.
7. Keep the file — contract, W-9, invoices, payment evidence, classification note — and review at 12 months, because long, exclusive, full-time engagements drift towards employment and PE.
For one or two genuine freelancers, a direct contract with a W-9 on file is usually proportionate. A contractor platform adds compliance checks, classification screening and payment rails for a fee, but does not transfer legal responsibility for status.
An employer of record is the right answer when the relationship is really employment: the EOR employs the individual in the US, runs payroll and benefits, and you buy their time under a services contract. It costs more per head but removes the misclassification exposure and the need to register in the state. Your own US entity earns its keep when headcount, revenue or customer expectations justify it. Our guide to employer of record versus entity setup compares them.
Most UK companies paying one or two American freelancers can run this themselves with a W-9, a sound statement of work and a reverse-charge entry. Get advice when the facts shade towards a US footprint: someone signing in your name, a US office, several full-time people in one state, or a payee who is not a US person.
