Why Consultants Need a Specialist Accountant, Not a Generic One

IR35 legislation, the off-payroll working rules (Chapter 10 ITEPA 2003), salary/dividend optimisation, the Flat Rate VAT Scheme and contract structure — these are the specific, high-value areas where a specialist consultant accountant delivers immediate, quantifiable savings that a generic small business accountant is unlikely to provide.

IR35 and off-payroll working is the defining tax issue for UK contractors and consultants in 2026. Chapter 8 (private sector) IR35 applies when a contractor provides services through their own limited company but would be an employee if engaged directly. If caught by IR35, the contractor’s company pays tax and NIC as if the income were salary — eliminating the tax efficiency of operating through a limited company. For medium and large end-clients, off-payroll working (Chapter 10) requires the client (not the contractor) to make the employment status determination and operate PAYE if inside IR35. We provide detailed IR35 status assessments and review contract and working practice alignment.

Limited company vs sole trader is the foundational decision for every consultant. A sole trader pays income tax and Class 4 NIC on all profits — at 40–45% above £50,270. A limited company pays 19–25% corporation tax on profits, and the director-shareholder draws a salary (below the NIC threshold) plus dividends (taxed at 8.75–33.75%, without NIC). For a consultant earning £60,000–£150,000 in fees, the limited company route typically saves £8,000–£25,000 per year in tax — after accounting for additional accountancy costs.

Flat Rate VAT Scheme is available to VAT-registered businesses with turnover below £150,000. Under the FRS, you charge VAT at 20% to clients but pay HMRC a flat rate percentage based on your industry sector — typically 14.5% for most consultancy services. The difference between 20% (charged) and 14.5% (paid) is profit — typically £1,500–£4,000 per year for a consultant billing £60,000–£100,000. We assess FRS eligibility and calculate the benefit for every VAT-registered consultant client.

The ‘travelling and subsistence’ rules for consultants operating through limited companies were significantly tightened by the 2016 Finance Act. Contractors working at a single ‘temporary workplace’ for an extended period (typically more than 2 years) cannot claim travel costs as business expenses through their company. This catches many long-term consultants who assume they can claim daily travel costs indefinitely. We review temporary workplace status and advise on allowable expense claims.

Industry Intelligence

2026 Outlook — Tax & Finance for Consultants & Freelancers

IR35 reform has been fully bedded in since April 2021 for medium and large private sector clients. HMRC’s Employment Status Manual (ESM) remains the primary reference — but HMRC’s CEST (Check Employment Status for Tax) tool is widely criticised for providing incorrect assessments in borderline cases. The leading cases — Christa Ackroyd, Kickabout Productions, PGMOL v HMRC (Supreme Court 2025) — continue to refine how mutuality of obligation and control are applied. We use a detailed questionnaire-based status assessment that goes beyond CEST and reflects current case law.

Off-payroll working (Chapter 10) for medium/large end-clients requires the client to issue a Status Determination Statement (SDS) before the engagement starts. Contractors can dispute an inside-IR35 determination via the client’s status disagreement process. HMRC’s current enforcement focus is on contractors who received outside-IR35 SDSs but whose working practices are actually inside — a growing area of investigation.

Making Tax Digital for Income Tax (MTD ITSA) will apply to self-employed individuals and landlords with income above £50,000 from April 2026. Affected sole traders will need to submit quarterly digital updates to HMRC. Sole trader consultants with income above this threshold should ensure they are using MTD-compatible software before the deadline.

The fiscal drag effect of frozen income tax thresholds (the personal allowance, basic rate band and higher rate threshold are frozen until 2028) means that consultants whose day rates increase with inflation are progressively paying more tax each year. Annual salary/dividend optimisation review — which we provide for all limited company clients — is more valuable than ever in a frozen-threshold environment.

Common Questions

Frequently Asked Questions — Consultants & Freelancers

Am I inside or outside IR35?

IR35 status depends on three key factors: (1) Control — does the client direct how, when and where you work? (2) Substitution — can you send a substitute to do the work? (3) Mutuality of obligation — are you obliged to accept and complete work, and is the client obliged to provide it? If control is high, substitution is not genuine and there is an obligation on both sides, IR35 risk is significant. We provide a written status opinion based on your specific contracts and working practices.

Should I operate as a limited company or sole trader?

For consultants earning above £35,000 in fees, a limited company typically produces a lower total tax bill — the difference being the ability to take dividends (no NIC, lower income tax rate) rather than trading profit (subject to both income tax and Class 4 NIC). The advantage narrows above £100,000 (additional rate, dividend additional rate). We model the comparison for your specific income level and circumstances.

What is the Flat Rate VAT Scheme?

Under the FRS, you charge clients VAT at 20% but pay HMRC a fixed percentage of gross turnover (including VAT) rather than the difference between input and output VAT. For most consultancy sectors, the FRS rate is 14.5% — so you charge 20% and pay 14.5%, keeping the 5.5% difference. For a consultant billing £80,000 + VAT (£96,000 gross), the FRS saving is approximately £2,640/year. The FRS is only available if turnover is below £150,000.

What business expenses can I claim through my limited company?

Fully deductible business expenses include: professional subscriptions and memberships, business software and IT equipment, mobile phone (business portion), business insurance, accountancy fees, continuing professional development, home office costs (fixed rate or actual calculation), business travel (where not caught by the temporary workplace rules) and work clothing (where wholly and exclusively for business). Personal clothing, commuting costs and client entertainment are generally not allowable.

Do I need to register for VAT?

Mandatory VAT registration applies when your taxable turnover exceeds £90,000 in any rolling 12-month period. For consultants below this threshold, voluntary VAT registration may still be beneficial — particularly if your clients are VAT-registered businesses (as they reclaim input VAT, making your gross prices neutral to them) and if you have VAT-bearing costs to reclaim. We assess the optimal VAT position for each consultant client.

Watch Out For

4 Costly Mistakes — and How to Avoid Them

❌ Not reviewing IR35 position when moving to a new contract

Most IR35 investigations are triggered by a change in contract — a renewal, a new client or a change in working arrangements. Reviewing your IR35 position only once and then ignoring it on subsequent contracts is common and dangerous. Each new contract must be assessed independently.

❌ Using the Actual Cost method for home office expenses instead of the fixed rate

HMRC’s fixed-rate home office deduction (£6/week for limited company directors using their home as an office) is simpler than the actual cost calculation and, for most consultants, nearly as tax-efficient. However, if you have a dedicated room used exclusively for business, the actual cost calculation is significantly more valuable.

❌ Not taking a salary above zero when operating through a limited company

Many contractor limited companies operate with zero salary to avoid employer NIC. However, taking a small salary (up to the NIC Secondary Threshold, currently £5,000) preserves qualifying years for State Pension and Employment Allowance eligibility. In most cases, a salary of £9,100–£12,570 is optimal — within the NIC Primary Threshold (no employee NIC) but above the Lower Earnings Limit (NIC qualifying year counted).

❌ Drawing excessive dividends in March to beat the year-end

Taking large dividends in a single month creates a personal tax spike in that tax year — potentially pushing income into the additional rate band. Spreading dividends evenly across the year, or timing them to align with personal allowance utilisation, is more efficient. We provide quarterly dividend planning for all limited company clients.
