Contractor Payroll Finance UK FAQ

What is contractor payroll finance?

Specialist UK working capital finance for recruitment agencies running contractor desks. Funds weekly contractor payroll outflow against monthly client invoice inflow, with payroll and compliance support that varies by provider.

How does IR35 affect contractor payroll finance?

Inside IR35: the fee-payer (often the agency) must deduct income tax and NICs from payments for the contractor's services, as if they were employed, whether the contractor works through a limited company (PSC) or an umbrella. Outside IR35: the contractor invoices through their own PSC with no deductions.

The end-client issues a Status Determination Statement (SDS) for each engagement. The finance provider doesn't carry IR35 liability (that sits with the agency or end-client) but their tech makes status determination easier.

Umbrella vs PSC vs PAYE payroll routing?

Three routes: (1) PAYE direct: contractor employed by agency, agency runs PAYE, simplest but agency carries employment liability. (2) Umbrella: contractor employed by umbrella company (NoPalaver, Parasol, Brookson), agency pays umbrella, umbrella runs PAYE. Reduces agency liability. (3) PSC: contractor's limited company invoices agency, agency pays gross, contractor handles tax. Mostly used for outside-IR35 engagements. Check which routes a provider supports before signing.

Healthcare locum agency finance?

Locum recruitment (NHS doctors, nurses, AHP) uses the same underlying contractor payroll finance, with three specifics: NHS Standard Contract terms (typically 30-day payment), framework agreement compliance (Health Trust Europe, NHS SBS), and IR35 inside-determination across most NHS engagements. Ask each provider about its experience with healthcare locum agencies.
