Are you losing money as a contractor?

Many Contractors Pay More Tax Than They Need To

Running a limited company can be highly tax-efficient — but only when structured correctly. These are the issues we help contractors solve every day.

Limited Company or Umbrella?

Unsure whether to operate through a limited company or umbrella company — each has different tax implications.

Concerned About IR35

Blanket assessments, unclear SDS determinations, and the fear of getting caught inside IR35 on your next contract.

Wrong Salary & Dividend Mix

Taking the wrong split costs thousands per year. The optimal extraction strategy changes with every Budget.

Missing Legitimate Expenses

Hardware, software licences, certifications, home office costs — most contractors leave money on the table.

VAT & Bookkeeping Headaches

Flat rate vs standard VAT, quarterly returns, MTD submissions — admin that eats into your contracting time.

Year-End Tax Surprises

No proactive planning means unexpected Corporation Tax or personal tax bills at the worst possible time.

We’ll review your current setup and identify opportunities to improve your take-home pay.

Why AccTek

An IT contractor accountant that works the way you need

Most accounting firms treat IT contractors like any other limited company client. They miss IR35 risks, don’t understand blanket assessments, and have never heard of bench-time planning. AccTek is built differently.

A Personal, Friendly Touch

A dedicated accountant who understands your work pattern, knows your financial goals and provides advice tailored to your situation — not generic templated returns.

IR35 Contract Reviews

Every new contract reviewed against HMRC’s IR35 indicators. Blanket inside determinations challenged with evidence-based arguments specific to your role and working practices.

Proactive Tax Planning

We model your salary, dividends, pension timing and expenses to maximise retention — typically 75–80% of gross billings vs 60–65% without planning.

Bench-Time Planning

Cash reserves, dividend timing, pension contributions and training investment — we build gap planning into your strategy from day one, not as a reaction when the contract ends.

Fixed Monthly Fees

From £19.99/month. No hidden charges, no hourly billing, no surprise invoices. Your fee is agreed upfront and stays fixed.

MTD Ready & Cloud-Based

Xero integration, live bank feeds, quarterly MTD submissions and a client portal for documents. Email queries answered the same working day.

Frequently asked questions

What makes AccTek different for IT contractors?
AccTek is a chartered accountancy practice that specialises in IT and tech contractor taxation. Every client works with a named chartered accountant who reviews IR35 contracts, optimises salary and dividend extraction, builds bench-time financial strategies and provides same-day support. Fixed fees from £19.99/month.
How does IR35 affect IT contractors specifically?
Since April 2021, medium and large end clients determine your IR35 status via a Status Determination Statement. If determined inside IR35, the fee-payer (usually the agency) deducts tax and NI before paying you. AccTek reviews contracts and working practices to ensure determinations are accurate and challengeable where wrong.
What should I do if I receive an inside IR35 determination?
You have the right to dispute the determination. AccTek reviews the SDS against HMRC’s CEST criteria, identifies weaknesses and helps you prepare a formal challenge. Many blanket assessments do not withstand scrutiny when properly contested with evidence of your actual working arrangements.
What tech expenses can IT contractors claim?
Laptops, monitors, peripherals, software licences, cloud hosting (AWS, Azure, GCP), domain names, professional certifications, training courses, co-working space, broadband, professional indemnity insurance and business travel between client sites. AccTek captures every allowable deduction.
Should IT contractors use the flat rate VAT scheme?
Rarely. The limited cost trader rate of 16.5% applies to most IT contractors (low material costs), making flat rate uncompetitive. Standard VAT accounting typically offers better recovery on expenses. AccTek models both schemes with your actual numbers before advising.
How should I plan financially between contracts?
Maintain 3–6 months of operating costs as a cash reserve. Time dividend extractions and pension contributions to smooth cash flow during bench periods. Invest in certifications that increase your next contract rate. AccTek builds bench-time planning into your annual tax strategy from day one.
How much can an IT contractor save with proper tax planning?
A contractor billing £500/day outside IR35, working 230 days, with optimised salary, dividend and pension structuring typically retains 75–80% of gross billings. Without planning, that drops to 60–65%. The difference is £15,000–£25,000 per year.
Does AccTek review contracts for IR35?
Yes. We review contracts and working practices against HMRC’s IR35 indicators — right of substitution, mutuality of obligation, control and financial risk. We advise on amendments that strengthen your outside IR35 position and flag risks before you sign.
What is a blanket IR35 assessment and can I challenge it?
A blanket assessment is when an end client determines all contractors as inside IR35 regardless of individual circumstances. This does not comply with the legislation, which requires individual assessment. AccTek helps you challenge blanket determinations with evidence-based arguments specific to your role and working practices.

Switching to AccTek is painless — we handle everything

Most IT contractors we work with are switching from another firm. If your current accountant doesn’t review IR35 contracts, doesn’t understand tech expenses, or only contacts you at year-end, you deserve better.

  1. You sign up — takes two minutes via our Instant Quote. No obligation until you’re ready.
  2. We handle professional clearance — we contact your outgoing accountant, request your records and manage the handover. No awkward conversations needed.
  3. You’re live within two weeks — Xero set up, bank feeds connected, IR35 position reviewed. No gap in service, no missed deadlines.

We catch up any outstanding filings from your previous accountant at no extra charge.

Why IT contractors need a specialist accountant
Direct answer

IT and tech contractors face a unique combination of high day rates, IR35 scrutiny from end clients, blanket assessments by agencies, complex expense profiles and gaps between contracts. A general accountant handles the filings — a specialist IT contractor accountant maximises what you keep.

If you are a software developer, data engineer, DevOps specialist, architect, cybersecurity consultant or project manager contracting through a limited company, your tax position is fundamentally different from a permanent employee doing the same work. The right structure, the right expense claims and the right IR35 strategy can mean the difference between retaining 75–80% of your gross billings or losing 35–40% to avoidable tax.

AccTek works specifically with IT and tech contractors. We understand your market, your contracts and the commercial realities of contracting in the UK technology sector.

IR35 and off-payroll working — the IT contractor reality

Since April 2021, medium and large end clients determine your IR35 status via a Status Determination Statement (SDS). For IT contractors, this has created a divided market — some clients assess individually, others issue blanket “inside” determinations to avoid risk.

What AccTek does that most accountants do not

Contract review against CEST criteriaWe review your contract and working practices against HMRC’s actual IR35 indicators — right of substitution, mutuality of obligation, control and financial risk. Not a generic checklist, but a line-by-line assessment with recommendations.
SDS challenge supportIf you receive an inside IR35 determination you believe is wrong, AccTek prepares evidence-based challenges using your actual working arrangements — many blanket assessments do not withstand scrutiny.
Inside IR35 strategyIf a contract is genuinely inside IR35, we advise on umbrella vs inside-IR35 limited company, expense recovery, pension contributions within deemed employment rules and whether the rate still makes financial sense.
Ongoing compliance monitoringIR35 is not a one-time assessment. As your working practices evolve, so does your status. AccTek reviews each new contract and flags changes that could affect your determination.

What an IT contractor actually keeps — outside IR35

A properly structured limited company with optimised salary, dividends and pension contributions retains significantly more than an umbrella or inside-IR35 arrangement:

Line Item£500/day × 230 days
Gross billings£115,000
Less: business expenses£5,500
Less: employer pension contribution£20,000
Less: Corporation Tax (on remaining profit)£10,200
Less: director salary (NI-efficient threshold)£12,570
Less: dividend tax£5,800
Total retained (salary + dividends + pension)£88,500 (77%)

Compare this to an umbrella where the same £115,000 yields approximately £72,000–£75,000. The difference is £13,000–£16,000 per year.

Figures are illustrative for 2026/27. Your actual position depends on expenses, pension strategy and personal circumstances.

Allowable expenses for IT contractors

IT contractors have a distinct expense profile. Beyond the standard contractor expenses, tech professionals can claim:

💻 Hardware & Equipment

  • Laptops, monitors, peripherals
  • Docking stations and cables
  • Standing desks and ergonomic equipment
  • Mobile phones and tablets
  • Network equipment

📊 Software & Cloud

  • IDE licences (JetBrains, VS Code)
  • Cloud hosting (AWS, Azure, GCP)
  • SaaS subscriptions (Jira, Confluence, Slack)
  • Domain names and SSL certificates
  • VPN and security tools

🎓 Training & Certifications

  • AWS / Azure / GCP certifications
  • CISSP, CISM, CEH
  • Agile, Scrum, PRINCE2
  • Pluralsight, Udemy for Business
  • Conference tickets and meetups

💼 Business & Professional

  • Professional indemnity insurance
  • Public liability insurance
  • Co-working space or serviced office
  • Home office allowance
  • Business travel and mileage

Most IT contractors we onboard have been missing £2,000–£5,000 in annual deductions — that is £380–£950 of unnecessary Corporation Tax every year.

Between contracts — bench-time financial planning

Gaps between contracts are normal in IT contracting. The question is whether you have planned for them financially:

  • Cash reserve strategy — maintain 3–6 months of operating costs as working capital
  • Dividend timing — extracting dividends during bench time when your marginal rate may be lower can reduce total tax across the year
  • Pension contributions — employer contributions during quiet periods use company profits tax-efficiently
  • Training investment — bench time is ideal for certifications — the expense reduces Corporation Tax and increases your next rate
  • Company year-end planning — if year end falls during a bench period, your profit and tax may be lower — we help you use this strategically

We build these strategies into your annual plan from day one — not as a reaction when the gap happens.
