UK contractor accountants start from £44/month for single-engagement Ltd-company contractors. Multi-engagement or higher-rate contractors typically pay £75-£150/month including IR35 advisory, monthly take-home modelling, dividend optimisation and director payroll. Umbrella users pay nothing for accounting (the umbrella handles it) but have higher margin loss; the matched firms can model both side-by-side.
IR35 is the UK tax legislation that determines whether a contractor working through a limited company is genuinely self-employed (outside IR35) or effectively an employee of the client (inside IR35). Inside-IR35 work is taxed roughly the same as employment, while outside-IR35 contracting can be significantly more tax-efficient. Status determination depends on the actual working relationship, not just the contract.
For inside-IR35 contracts, umbrella is often the simplest option. For outside-IR35 work, a limited company is usually more tax-efficient. The right answer depends on your contract mix and income band — a specialist accountant will model both.
