If you’re operating through a limited company, you need an accountant who understands PSCs: salary and dividend splits, allowable expenses, VAT, and annual filings with Companies House and HMRC. That’s what the accountants above specialise in.
If you’re inside IR35 or on shorter engagements, an umbrella company may be simpler. Several of the firms listed here (such as Dolan Accountancy) offer both limited company and umbrella services, so you can switch between structures without changing provider.
One change worth knowing if you go umbrella: for payments made on or after 6 April 2026, the agency closest to the client (or the client itself where there is no UK agency) is jointly and severally liable for PAYE the umbrella fails to account for. The umbrella still runs the payroll and your take-home is unaffected, but everyone in the chain now has a reason to care whether it is compliant.

Contractor accountant fees on ContractorUK typically range from £60 to £150 per month in 2026. Prices start around £60-80/month for promotional rates, mid-range services cost £105-120/month, and comprehensive packages with IR35 support and legal helplines cost £120-150/month. Many packages include bookkeeping software (FreeAgent, Xero, or QuickBooks), annual accounts, self-assessment tax returns, and VAT filing as standard.
When choosing a contractor accountant, prioritise these key factors:
Yes, having an IR35 specialist accountant is highly recommended for all UK contractors. A specialist contractor accountant will review your contracts for IR35 risk, advise on working practices to maintain outside-IR35 status, prepare status determination statements, handle off-payroll assessments, and represent you in HMRC enquiries.
For 2026/27 the off-payroll rules themselves are unchanged: medium and large private-sector clients, and all public bodies, decide your status. A private-sector client only counts as small (leaving the decision with your own company) if it does not exceed two of the three thresholds of £10.2m turnover, £5.1m balance sheet total and 50 employees. If you disagree with a status determination statement you have 45 days to challenge it.
Yes, you can switch contractor accountants at any time during your financial year. Many accountants listed on Contractor UK will handle the transition for you, including requesting records from your previous accountant and notifying HMRC of the change. Some accountants offer free catch-up work to bring your books up to date. The tidiest moment to move is just after your company's year-end (its accounting reference date, which is not usually 5 April) or at the start of the tax year on 6 April, but switching mid-year is straightforward with professional support.
While not legally required, having a specialist contractor accountant for your limited company is highly recommended. They ensure compliance with Companies House and HMRC filing requirements, maximise your tax efficiency through optimal salary/dividend planning, handle complex IR35 assessments and contract reviews, save you significant time on bookkeeping and administration, and provide expert advice on allowable expenses, VAT registration, and tax planning strategies. Most contractors save £2,000-5,000 per year through proper tax planning alone.
Contractor accountants specialise in the unique needs of UK contractors and freelancers, offering specific expertise that regular accountants often lack:
Regular accountants may not understand these contractor-specific nuances, potentially costing you thousands in missed tax savings or IR35 compliance issues.
Standard contractor accounting packages typically include:
Premium packages may also include legal helplines, tax investigation insurance, crypto accounting, property/rental income support, and multi-director services.
FreeAgent is the most popular choice for UK contractors as it's specifically designed for freelancers and small limited companies. It includes features like automatic mileage tracking, expense categorisation, and tax estimates. Xero is more powerful and scalable if you plan to grow into a larger business with employees. QuickBooks is user-friendly but less contractor-focused. Many ContractorUK recommended accountants work with FreeAgent, which is ideal for most contractors. Your accountant will advise on the best software option for your specific situation.
All Contractor UK recommended accountants serve contractors across London and the UK. With modern cloud accounting software and video calls, location is no longer a barrier to receiving expert service. London-based contractors benefit from accountants who understand the capital's higher day rates, agency contracts, and financial services sector requirements. Whether you're contracting in the City, Canary Wharf, or working remotely, the accountants listed above provide the same specialist IR35 and tax planning support to London contractors as they do nationwide.
Yes, freelancers operating through a limited company face the same tax, IR35, and compliance obligations as contractors. A specialist freelancer accountant understands the nuances of variable income, project-based work, and the unique challenges of self-employment. They can advise on whether a limited company or sole trader structure is more tax-efficient for your situation, help you claim all allowable expenses, and keep you the right side of Making Tax Digital.
Check which MTD applies to you: MTD for Income Tax became mandatory on 6 April 2026 for sole traders and landlords whose 2024/25 qualifying income was over £50,000, with over £30,000 following in April 2027 and over £20,000 in April 2028. It does not apply to a limited company, but MTD for VAT does if the company is VAT registered. The accountants listed on this page work with freelancers across IT, creative, consulting and engineering sectors.
