The quick answer
- Pay genuine contractors in GBP (£) over Faster Payments, BACS, SWIFT.
- Misclassification risk is High — the test is IR35 / off-payroll working.
- Cheapest clean route is a usage-based payout platform (4dev.com, 3% or less); use an EOR only if the person is really an employee.
The UK’s off-payroll (IR35) rules turn on whether a contractor would be an employee “but for” their limited company. For medium and large clients, the responsibility to determine status sits with the client, and getting it wrong carries tax and NIC liability. Payment itself is trivial — Faster Payments is instant.
For genuinely outside-IR35 contractors, pay their invoices in GBP, handle VAT if they’re registered, and keep a defensible status determination on file. Inside-IR35 or employee-like relationships point to an EOR or PAYE.
How to pay a contractor in the United Kingdom, step by step
- Classify the worker correctly. the United Kingdom’s test turns on IR35 / off-payroll working. If the person is, in substance, an employee, you need an Employer of Record — paying them as a contractor won’t protect you.
- Put it in a written contractor agreement — scope, deliverables, IP assignment and clear signs of independence (own tools, own hours, multiple clients).
- Choose a payment method. Pay in GBP (£) over Faster Payments, BACS, SWIFT. For a genuine contractor, a payout platform or a rail is enough; you don’t need employment machinery.
- Pay and handle tax. 20% VAT (register above threshold). If you’re a US payer, collect a W-8 and file 1099/1042-S as required.
- Keep records that prove independence — the agreement, invoices and payment history are what protect you if the relationship is ever questioned.
