A non-resident founder's first UK hire is almost always a contractor — a designer, a developer, an accountant, a fractional operator — engaged through their own limited company or as a sole trader, paid against an invoice. This is the right first move. It gives the founder access to UK talent, keeps overheads variable, and avoids the compliance weight of payroll and employment law before the business is ready for it.
It also carries structural risk if done casually. HMRC enforces a hard distinction between genuine self-employment and disguised employment, and it enforces it retrospectively. A poorly-documented contractor engagement that HMRC later reclassifies as employment can trigger PAYE, employer's NIC, employee's NIC, penalties and interest going back years. The paperwork below is not administrative overhead — it is the difference between a variable-cost contractor and an accidental permanent employee.
Why non-resident founders start with contractors
A UK employee brings four obligations that a UK contractor does not. First, monthly PAYE payroll — registration with HMRC as an employer, real-time information filings, payslips, P60s, P45s. Second, employer's National Insurance contributions at 15% on earnings above £5,000 (2026 rate), before any employee cost. Third, statutory pension auto-enrolment with a minimum 3% employer contribution. Fourth, employment law — holiday pay, statutory sick pay, notice periods, unfair-dismissal protection after two years.
For a founder based in Riyadh, Dubai, Delhi or Lagos, running a UK payroll from overseas is possible but requires either a UK accountant, a payroll bureau, or an EOR (employer of record). None of these are wrong; they are just heavier than a contractor arrangement while the business is finding its shape. Most founders we work with engage contractors for the first two to five UK relationships, then convert to employment where a permanent, integrated role emerges.
The employment status test — what actually decides
UK employment status is determined by six factors distilled from over half a century of case law and codified into HMRC's Employment Status Manual. No single factor is decisive; a tribunal or HMRC officer weighs the whole picture. The table below is the working guide we use before every material engagement.
| Factor | Looks like employment | Looks like a contractor |
|---|---|---|
| Control | Client dictates when, where and how the work is done. Set hours, on-site presence, direct supervision. | Contractor decides how the work is performed, with agreed deliverables and deadlines but no line-manager oversight. |
| Substitution | The individual must personally do the work. No right to send someone else. | Genuine right to send a qualified substitute. Even better if it has been exercised at least once. |
| Mutuality of obligation | Client must offer work; individual must accept it. Ongoing expectation of both sides. | Engagement is for a defined piece of work or a fixed term. No obligation to offer more; no obligation to accept. |
| Financial risk | Paid regardless of outcome. No investment in tools, insurance or premises. | Bears real risk — fixing defective work at own cost, PI insurance, own equipment, own premises. |
| Integration | Uses company email, has a job title, appears on the org chart, attends internal meetings, receives benefits. | Sits outside the org chart. External email, no benefits, no equity, no internal announcements. |
| Part and parcel | Is 'part and parcel' of the organisation — a fixed feature of how it operates. | Provides a discrete service alongside other clients, without becoming part of the client organisation. |
HMRC's CEST tool codifies these factors but is not binding on HMRC. Use it as evidence, not as a guarantee.
IR35 and off-payroll rules in plain English
IR35 is anti-avoidance legislation targeting individuals who would be employees but for the interposition of a personal service company (PSC) — typically a one-person limited company. The rules ask: strip out the PSC, and would this look like employment? If yes, the engagement is 'inside IR35' and employment taxes apply.
Two regimes coexist. Chapter 8 ITEPA (the original IR35) puts the determination and tax liability on the contractor's own PSC. Chapter 10 ITEPA (the off-payroll rules) shifts that responsibility to the client if the client is a medium or large private company. The Companies Act size tests define 'small': turnover ≤ £10.2m, balance sheet ≤ £5.1m, employees ≤ 50 — with two of three needed to qualify as small for two consecutive years.
Almost every UK Limited Company owned by a non-resident founder in its first three years falls squarely within 'small'. That means Chapter 10 does not apply. The contractor's own PSC handles the IR35 determination. The client's obligations reduce to running the engagement as a genuine business-to-business contract — which is exactly what the status factors above codify.
Growing past 'small' triggers Chapter 10 obligations from the tax year after the second consecutive year of exceeding the tests. Model this in your growth plan — first-time Status Determination Statement workflows require lead time, not a rushed retrofit.
Eight contract clauses every contractor engagement needs
Name the parties precisely — your UK Limited Company and the contractor's limited company or personal name. Define the services by deliverable, not by role. 'Design and deliver three landing pages by 30 September 2026' is a contract for services. 'Perform marketing duties as directed' looks like employment.
Fixed term with a defined end date, or project-based with completion criteria. Include a notice period (7–30 days) and immediate termination for material breach. Rolling one-month contracts with no defined project are a red flag for HMRC.
Day rate or fixed price, plus VAT if the contractor is VAT-registered. State payment terms clearly — 14 or 30 days from invoice is standard. Include what triggers payment: completion of deliverables, milestone acceptance, or elapsed time.
Explicit right for the contractor to send a suitably qualified substitute at their own cost. Not a token clause — HMRC and the tribunals look for evidence the right is genuine and unfettered. Requiring your prior approval, or restricting substitutes to the contractor's own employees, weakens the clause.
State that neither party is obliged to offer or accept further work beyond this contract. Avoid language suggesting an ongoing relationship or a right to further engagements.
Confirm the contractor operates their own business, provides services to other clients, uses their own tools and equipment, and holds appropriate professional indemnity insurance. This is not a marketing clause — it evidences status.
For work delivered under the contract, assign all intellectual property to your UK company on payment. Without this clause, IP legally rests with the contractor even after full payment. Include moral rights waivers where relevant.
NDA covering all commercial and personal data. UK GDPR data-processing terms if the contractor will handle personal data on your behalf. A data-processing addendum is separate from the main contract and mandatory under UK GDPR Article 28.
Invoicing, payment terms and currency
UK contractors expect to invoice against completed work or agreed milestones. A compliant UK invoice must show: the contractor's legal name and address, their company number if incorporated, your company's legal name and address, invoice number and date, a description of services, the amount due, and — if VAT-registered — their VAT number, the VAT rate and the VAT amount separately.
Pay in GBP into a UK bank account or Wise Business GBP balance. Cross-border payments to a UK contractor from a non-UK account often incur multiple correspondent-bank fees and unfavourable FX, and can prompt the contractor's own bank to run enhanced due diligence, delaying receipt by days. Wise Business accounts provide GBP details indistinguishable from a UK current account — indispensable for a non-resident founder in the first year.
Standard payment terms are 14 or 30 days from invoice date. Longer terms are a competitive disadvantage in a UK market where good contractors have their pick of clients. Late payment attracts statutory interest under the Late Payment of Commercial Debts (Interest) Act 1998 — currently base rate + 8% — and is a fast route to contractor churn.
The paperwork stack before the first invoice
- Written Services Agreement signed by both parties before work begins
- Companies House check of the contractor's PSC — active status, filings current, no strike-off proposed
- Contractor's professional indemnity insurance certificate on file
- UK GDPR data-processing addendum if the contractor will handle personal data
- CEST tool result printed and saved with the engagement file
- Purchase order or scope-of-work document confirming the deliverables and price
- Onboarding email confirming payment terms, invoice format and bank details
- Anti-Money Laundering ID check for engagements above materiality thresholds
Six mistakes we fix every month
Labels do not determine status — the reality does. An individual working set hours, using your equipment, taking direction from your team and paid monthly regardless of output is an employee, whatever the contract calls them. HMRC can reclassify retrospectively and charge PAYE, NIC and penalties for up to 20 years.
'A handshake and an invoice' is not enough. Without a written agreement you have no IP assignment, no confidentiality, no substitution right — and no evidence of business-to-business intent if HMRC asks. Non-resident founders operating internationally are particularly exposed because there is no local team to sort it out later.
Never mix company and personal payments. Every contractor payment must come from the UK company's bank account or approved EMI. Payments from a founder's personal account are director's-loan-account transactions that create tax exposure and diligence noise.
If your UK Limited Company grows past the 'small' size thresholds — over £10.2m turnover, over £5.1m balance sheet, over 50 employees on two of three tests — off-payroll obligations shift to you. You must issue a Status Determination Statement to the contractor and their fee-payer, and account for tax if the engagement is inside IR35.
HMRC's Check Employment Status for Tax (CEST) tool is imperfect but provides evidence. Run it before any material engagement, save the result, and keep contemporaneous notes of the commercial reasons for the engagement. Reconstructed narratives never survive scrutiny.
Non-resident founders often assume 'contractor' means the same everywhere. A UK-resident contractor is subject to UK employment and tax law; a contractor resident abroad performing services from abroad is not. Get the contractor's residence in writing at the start of the engagement — it changes everything.

Do I need employers' liability insurance to engage a contractor?+
No. Employers' liability insurance is mandatory only if you have employees under a contract of service. Genuine contractors are not employees. You should still hold public liability insurance appropriate to your activities, and require the contractor to carry their own professional indemnity insurance.
Can a UK contractor invoice my UK company from outside the UK?+
Yes — physical location of the invoice is irrelevant. What matters is where the contractor is tax-resident and where the services are performed. A UK-resident contractor working temporarily abroad is still a UK-taxable individual; a non-UK-resident contractor performing services outside the UK is outside UK employment tax entirely (though other jurisdictions may apply).
What is a Status Determination Statement (SDS)?+
Under Chapter 10 ITEPA (the off-payroll rules), a medium or large client engaging a contractor through a personal service company must issue a written statement confirming whether the engagement is inside or outside IR35, with reasons. It must be given to the contractor and the fee-payer, with a review process if disagreed. Small clients — under the Companies Act size tests — are exempt.
How much can I pay a UK contractor before it becomes complicated?+
There is no threshold — the same rules apply from the first pound to the last. What changes with scale is scrutiny: large single engagements or repeated payments at high day-rates attract more HMRC attention. Genuine business-to-business contracts at any value are fine; poorly-documented arrangements at any value are risky.
Do I need to register as an employer with HMRC to hire a contractor?+
No. PAYE registration is required only when you have employees or directors receiving salaries above the Lower Earnings Limit. Contractor engagements against invoice do not trigger PAYE registration. Register only when you are ready to run genuine payroll.
Can I pay a UK contractor from Wise Business or Revolut?+
Yes — both are widely accepted by UK contractors. Wise Business provides GBP account details with a UK sort code and account number, indistinguishable to the recipient from a high-street bank. Ensure the payment reference includes the contractor's invoice number for their bookkeeping.
Does a contractor need to be VAT-registered?+
No — VAT registration depends on the contractor's own turnover crossing the £90,000 threshold, not on any single client. If the contractor is registered, they charge you VAT which you can reclaim (subject to your own VAT position). If they are not registered, no VAT is charged. Check the invoice reflects their actual status.
What if my contractor is my spouse or a family member?+
HMRC scrutinises related-party engagements carefully. The commercial reality must stand up — genuine services delivered at market rates with normal contract terms. Payments that look like disguised remuneration or income-shifting will be challenged under the settlements legislation. Keep the paperwork identical to any third-party engagement.
