Contracting gives you freedom, flexibility, and higher earning potential. But it also lands you with IR35 assessments, limited company admin, VAT, and complex tax planning that standard accountants rarely understand. The gap between what you earn and what you keep is determined by how well your tax affairs are structured, not just how hard you work.
At Accountactical, we are the contractor accountants London professionals trust to maximise take-home pay while keeping every filing compliant. Whether you operate through a limited company, umbrella, or are navigating IR35, our accountants for contractors in London handle the complexity so you focus on delivering value to clients.
A high-street accountant who does not understand IR35, dividend strategy, or contractor-specific expenses can cost you thousands in missed tax savings and compliance failures. The contracting world operates under rules that generalist accountants encounter rarely, and the consequences of ignorance are expensive.
IR35 misclassification leads to HMRC investigations and backdated tax bills that can stretch across multiple years. An inefficient salary versus dividend mix means paying more tax than necessary, often thousands annually, because no one modelled the optimal combination. Missed expenses, travel, equipment, training, home office costs, professional subscriptions, all add up to significant unclaimed reliefs. And without specialist guidance, you have no visibility into optimal profit extraction or pension planning that could transform your long-term financial position.
Our accounting services for contractors and contractor accounting services are built around this reality. We do not treat you like a small business with a fancy title. We treat you like a professional with specific, and complex needs that demand specialist knowledge.
The structure through which you operate determines your tax efficiency, administrative burden, and financial flexibility. Making the wrong choice costs you money every month. Making the right one requires understanding the trade-offs clearly.
Limited Company is the most tax-efficient structure for contractors earning £400 or more per day working outside IR35. You pay yourself via a combination of salary and dividends, claim legitimate business expenses, and make pension contributions tax-free up to £60,000 per annum. Corporation tax applies at 19% to 25% depending on profit levels, with dividends taxed at 8.75% for basic rate taxpayers, 33.75% for higher rate, and 39.35% for additional rate. This structure gives you control over timing and amounts, but requires more admin and carries director responsibilities.
Umbrella Company makes you an employee of the umbrella. They handle PAYE, National Insurance, and administrative burdens. This works best for short-term contracts or inside-IR35 engagements where the client has determined you are a deemed employee.
The right choice depends on contract length, daily rate, IR35 status, and your appetite for administrative involvement. As leading contractor accountants UK wide, we help you model the real take-home difference between each structure.
From IR35 advice to tax planning and limited company accounts, we help contractors stay compliant and keep more earnings.
We review your contracts and working practices for IR35 status, identifying the factors that HMRC examines. Control, substitution, and mutuality of obligation are not abstract concepts for us. We apply them to your specific engagements. We support clients with Status Determination Statements, challenging incorrect inside-IR35 determinations where appropriate.
We handle company formation with Companies House, including registered office provision and confirmation statement filing. We guide you through director responsibilities, statutory filing requirements, and Companies House compliance. Your limited company is not just a vehicle for tax efficiency. It is a legal entity with obligations that we ensure you meet without stress.
We model your optimal salary versus dividend strategy, factoring in personal allowance, National Insurance thresholds, and dividend tax bands. We prepare your personal tax return, SA100, ensuring every relief is claimed. Our accounting specialists for contractors understand that your financial life extends beyond the current contract.
We manage VAT registration when your turnover approaches the threshold, currently £85,000. We prepare MTD-compliant VAT returns and advise whether the Flat Rate Scheme or Standard Accounting suits your contract profile. For contractors with minimal VAT-able expenses, Flat Rate can simplify reporting and reduce liability.
We run monthly payroll for directors and any employees, ensuring PAYE and National Insurance compliance. We set up auto-enrolment pension schemes and manage ongoing obligations. We track and reimburse legitimate expenses, travel, subsistence, equipment, training, ensuring every claim is documented and defensible.
We prepare annual accounts and file them with Companies House. We compute corporation tax accurately, identify every allowable deduction, and submit CT600 returns on time. Late filing penalties for corporation tax start at £100 and escalate. We ensure you never face them. Our contractor accounting service in London delivers compliance without the year-end panic.
Legitimate expense claims reduce your tax liability without attracting HMRC scrutiny. We ensure every allowable cost is captured correctly.
Business travel and subsistence, including mileage between client sites, overnight accommodation, and meals when working away from home. Equipment and software, laptops, monitors, specialist tools, and subscriptions necessary for your work. Professional subscriptions to industry bodies and training courses that maintain or enhance your skills. Home office costs, a proportion of utilities, rent, and council tax based on actual business use.
We ensure every legitimate expense is claimed. No missed reliefs that cost you money. No red-flag claims that trigger HMRC enquiries. Experienced contractors accountants know that proper expense tracking is as important as tax planning. It is the foundation on which everything else builds.

Yes, contractor accounting involves IR35, dividend strategy, VAT, and project-based income that standard accountants rarely encounter. A specialist maximises your take-home pay while keeping you compliant.
IR35, or Off-Payroll Working rules, determines whether you are genuinely self-employed or a disguised employee for tax purposes. Since April 2021, private sector clients will determine your status. Inside IR35 means higher tax like employment. Outside IR35 allows continued tax efficiency through dividends.
Limited companies suit higher-earning contractors outside IR35 who want maximum tax efficiency and control. Umbrella companies suit short-term contracts or inside-IR35 roles where simplicity matters more than tax savings. We model both scenarios with your actual numbers.
Legitimate expenses include business travel, equipment, professional subscriptions, home office costs, training, accountancy fees, insurance, and pension contributions. We ensure every claim is correct and defensible.
The optimal mix combines a small salary at the National Insurance threshold with dividends for remaining profits. This minimises National Insurance while keeping income tax efficient. Pension contributions provide additional tax relief.
Costs vary based on services required. Most contractors benefit from fixed monthly fees covering company accounts, payroll, VAT, self-assessment, and IR35 support. This provides predictable costs and ensures nothing is missed.
