Consultants face a unique set of tax challenges that generic accountants often miss. Here are the most common issues we help consulting professionals resolve:
IR35 remains the single biggest tax challenge for consultants in 2026. The off-payroll working rules apply to medium and large private sector clients, who are responsible for determining your IR35 status.
We help you understand your IR35 status, provide evidence to support your position, and ensure your Self Assessment accurately reflects your employment status — whether you're inside or outside IR35. Many consultants working in London and the South East have been affected by these rules.
Many consultants miss out on significant tax deductions because they don't know what they can claim. Common allowable expenses for consultants include:
Consultants typically operate through a limited company for tax efficiency, allowing you to take income as a combination of salary and dividends. However, the IR35 landscape and consulting model significantly influence which structure is best for your specific situation.
We help you determine the most tax-efficient structure for your consulting practice, manage your limited company compliance (including Corporation Tax, VAT, and payroll), and ensure you're not paying more tax than necessary.
Professional indemnity insurance is essential for consultants — and it's also tax-deductible. Many consultants in management, IT, and financial consulting carry significant PI cover, which can be a substantial expense.
We ensure you claim full tax relief on your professional indemnity insurance premiums, along with other insurance policies such as public liability and business interruption cover.
Many consultants work remotely, either from home or from co-working spaces like WeWork in London, Manchester, or Bristol. You can claim home office expenses for the proportion of your home used exclusively for business purposes.
We help you calculate and claim home office costs, including electricity, heating, internet, and a proportion of your rent or mortgage interest. The simplified flat rate is £6 per week, but we can help you claim more by calculating actual costs if they're higher.
Many consultants work for international clients or spend time working abroad. This creates complex cross-border tax issues, including double taxation, Statutory Residence Test, and withholding tax on foreign income.
We help consultants with international income, ensuring you're not paying tax twice on the same income and that you're compliant with both UK and foreign tax authorities. This is particularly relevant for consultants in London, which has a high concentration of international clients.
If your taxable turnover exceeds £90,000 (2026/27 threshold), you must register for VAT. Many consultants operate above this threshold, particularly those with long-term contracts or multiple clients.
We advise on VAT registration, VAT returns, and whether the Flat Rate Scheme is beneficial for your consulting business. We also help with reverse charge VAT on cross-border services.
Consultants have multiple tax deadlines to manage: Self Assessment, Corporation Tax, PAYE, and VAT. Missing any of these deadlines can result in automatic penalties that can be costly and time-consuming to resolve.
We help you stay on top of all your tax deadlines, ensuring you never miss a filing date. Our deadline checker can help you keep track of key dates, and we handle all submissions on your behalf.
We start by understanding your specific situation — whether you're operating through a limited company, your IR35 status, and what your consulting model looks like. This helps us tailor our service to your needs.
We'll guide you on exactly what documents you need for your tax return — including invoices, expense receipts, client contracts, and professional subscription records.
We'll identify every allowable expense unique to consulting — from professional subscriptions and indemnity insurance to travel, accommodation, and business development costs.
We'll review your contracts and working practices to assess your IR35 status, ensuring you're correctly classified and your Self Assessment reflects the right tax treatment.
Our ACCA-qualified accountants prepare your Self Assessment return, Corporation Tax return (if applicable), and VAT returns, double-checking all calculations before submission to HMRC.
Tax doesn't end with the return. We provide year-round support for tax planning, penalty avoidance, and strategic advice to help you build wealth efficiently.
Rachel is a Management Consultant based in London, specialising in organisational change and digital transformation. She operates through her own limited company (PSC) and works with clients across the UK and Europe. Her income breakdown for 2025-26 was:
Rachel approached us because she was concerned about her IR35 position — her largest client had recently reviewed all consultant roles and she was worried about being reclassified as inside IR35. She was also unsure about international tax implications for her European clients and whether she was claiming all allowable expenses through her limited company.
She had been using a generic accounting service that couldn't provide specialist IR35 advice or handle her cross-border tax issues. She was also concerned about her director's remuneration strategy and whether she was paying too much tax.
“I had no idea I could claim so many expenses through my limited company. The team at Right Tax Returns gave me confidence in my IR35 position and saved me thousands in tax through proper expense claims and remuneration planning. The international tax advice was invaluable for my European clients.”
— Rachel, Management Consultant
💰 Total tax saved through our advice: £4,200
Note: Corporation Tax rates have changed significantly, making tax planning more important than ever for consultants in London, Manchester, and across the UK.
Key change: HMRC's CEST tool remains the primary status determination tool, but its reliability has been questioned. We recommend professional IR35 reviews for all consultants, particularly those in London and the South East.
Important: Consultants operating through limited companies pay NI on salary but not on dividends, making the salary/dividend mix crucial for tax efficiency.
Tip: Consultants typically have multiple deadlines. Our deadline checker can help you stay on track.
Do I need to file a Self Assessment as a consultant in the UK?
Yes, if you operate through a limited company, work as a sole trader, or have income from consulting outside PAYE, you must file a Self Assessment. Even if you're a deemed employee under IR35, you may still need to report income depending on your circumstances.
What expenses can consultants claim on their tax return?
Consultants can claim professional subscriptions, travel and accommodation, home office costs, CPD courses, specialist equipment, professional indemnity insurance, and business development expenses. Many consultants miss out on claiming these essential deductions.
What is the difference between inside and outside IR35 for consultants?
If you are deemed outside IR35, you are considered truly self-employed and can operate through your limited company with full tax efficiency. If you are inside IR35, you are treated as an employee for tax purposes, and your limited company must deduct PAYE and National Insurance before paying you.
Can consultants claim travel expenses to client sites?
Yes, you can claim travel expenses for journeys to client sites, including train tickets, flights, hotels, and mileage. However, you cannot claim commuting from home to your regular place of work. If you work across multiple client sites, these expenses can add up significantly.
What is the deadline for consultants to file Self Assessment?
The online Self Assessment deadline is 31 January 2027 for the 2025-26 tax year. If you're filing a paper return, the deadline is 31 October 2026. We strongly recommend filing online by 31 January to avoid late filing penalties.
Should I operate through a limited company or as a sole trader as a consultant?
Consultants typically benefit from operating through a limited company for tax efficiency, allowing you to take income as a combination of salary and dividends. However, IR35 status and your consulting model significantly influence which structure is best for your specific situation. Consultants in London, Manchester, and Birmingham commonly operate through limited companies.
Can consultants claim home office expenses?
Yes, you can claim home office expenses if you work from home as a consultant. This includes a proportion of your electricity, heating, internet, and rent/mortgage interest. The simplified flat rate is £6 per week, but you may claim more by calculating actual costs.
What professional subscriptions can consultants claim?
Consultants can claim membership fees for professional bodies such as the Institute of Consulting, Management Consultancies Association, ACCA, and other industry-specific bodies that are relevant to their consulting practice.
