Contractor Accountants UK
Compare UK contractor accountants from £79/month — IR35 advice, PSC company accounts and dividend planning. Get matched with a specialist firm.
Contractors working through personal service companies (PSCs) face unique tax rules including IR35, dividend planning, and expense claims. A specialist contractor accountant understands inside/outside IR35 determinations, optimal salary-dividend splits, and MTD for Income Tax. Whether you are an IT contractor, consultant, or interim manager, the right accountant protects your take-home pay and keeps HMRC compliant.
Do I need a specialist contractor accountant?
Yes if you operate a personal service company and IR35, salary-dividend mix or expenses actually move your take-home pay. No if you invoice as a simple sole trader — a general small-business package is cheaper. Umbrella-only contractors often need payroll, not a PSC accountant.
Inside IR35 and outside IR35 are different products. A firm that cannot explain who makes the status determination (you, the client, or an agency) is not a specialist. Ask whether IR35 reviews are in the monthly fee or extra.
How much does a contractor accountant cost?
Contractor packages typically run £79–£149 per month on our editorial benchmarks, including annual accounts, corporation tax, payroll and dividend advice. IR35 reviews and specialist planning are often extra. Confirm the current quote — these are not live prices.
Compare against an umbrella illustration on the same day-rate before you assume the limited company wins. Online contractor firms often undercut high-street practices because of overhead, not because they skip the CT600.

Frequently asked questions
How much does a contractor accountant cost?▼
Contractor accountancy packages typically range from £79–£149 per month, including annual accounts, corporation tax, payroll, and dividend advice. IR35 review and specialist tax planning may cost extra.
Do I need a specialist contractor accountant?▼
If you operate through a limited company as a contractor, a specialist firm understands IR35, allowable expenses, and optimal salary-dividend splits better than a general small business accountant.
What is IR35 and do I need an accountant for it?▼
IR35 rules determine whether you are treated as employed or self-employed for tax purposes when working through a limited company. An accountant helps assess status, structure contracts, and ensure compliant tax treatment.
Contractor accountant vs umbrella company — which is cheaper?▼
A limited company with a contractor accountant often yields higher take-home pay for outside-IR35 contractors. Umbrella companies suit inside-IR35 assignments with simpler admin but higher effective tax rates.
