Professional Fees: Accountants, Solicitors, and Insurance

The Accounted Tax Team·17 March 2026·4 min read

Professional Fees Are Generally Allowable

When you hire professional advisers to help run your business — whether that's an accountant preparing your tax return, a solicitor reviewing a contract, or a consultant advising on strategy — the fees are usually allowable business expenses.

However, there are some important exceptions. Not all professional fees are deductible, and the purpose of the advice determines whether you can claim it.

Accountancy and Bookkeeping Fees

What's Allowable

  • Fees for preparing your business accounts
  • Tax return preparation (the business portion of your Self Assessment)
  • Bookkeeping services
  • Payroll processing
  • VAT return preparation
  • Tax advice related to your business
  • Management accounts
  • Year-end accounts preparation

What's Not Allowable

  • The personal element of your Self Assessment fee (if your accountant charges separately for personal tax matters unrelated to your business)
  • Tax planning for personal investments
  • Fees for non-business matters handled by your accountant

In practice, most accountancy fees for sole traders are entirely business-related and fully deductible. If there's a personal element, your accountant should separate the charges on their invoice.

Using Accounted for your bookkeeping? The subscription is fully tax-deductible as an accountancy and bookkeeping expense.

Legal Fees

What's Allowable

  • Contract review and drafting
  • Debt recovery costs
  • Employment law advice
  • Lease negotiation for business premises
  • Intellectual property protection (trademark registration, copyright)
  • Defending against claims related to your business
  • Regulatory compliance advice
  • Terms and conditions drafting

What's Not Allowable

  • Legal fees for buying a business property (this is capital expenditure)
  • Legal fees for forming a company (these are pre-trading expenses, treated differently)
  • Fines and penalties, even if a solicitor handles the matter
  • Legal fees for personal matters
  • Legal costs of acquiring a capital asset

The distinction between revenue and capital legal fees matters. If a solicitor helps you defend a breach-of-contract claim from a customer, that's a revenue expense. If a solicitor handles the purchase of your business premises, that's capital expenditure.

Insurance Premiums

Business insurance premiums are generally fully allowable:

  • Professional indemnity insurance — essential if you provide advice or services
  • Public liability insurance — covers claims from the public
  • Employer's liability insurance — compulsory if you employ anyone
  • Business premises insurance — buildings and contents
  • Business equipment insurance — tools, technology, stock
  • Product liability insurance — if you sell physical goods
  • Cyber insurance — increasingly important for all businesses
  • Business interruption insurance — covers lost income
  • Key person insurance — where the business pays the premium and is the beneficiary
  • Motor trade insurance — if you're in the motor industry

Insurance That's Not Allowable

  • Personal life insurance — even if you'd struggle to run your business without it
  • Private health insurance for yourself — this is a personal expense (though providing it to employees is allowable)
  • Home insurance — unless you claim the business proportion under actual costs for working from home

Consultant and Adviser Fees

If you hire consultants to help with business matters, their fees are allowable:

  • Business strategy consultants
  • Marketing consultants
  • IT consultants
  • HR advisers
  • Health and safety consultants
  • Financial advisers (for business matters, not personal financial planning)

The key test is whether the consultancy relates to your current trade. Advice on running your existing business is allowable. Advice on starting a completely different business is not.

Professional Body Subscriptions

Annual subscriptions to professional bodies are allowable if membership is relevant to your trade:

  • ICAEW, ACCA, CIMA (for accountants)
  • Law Society (for solicitors)
  • RICS (for surveyors)
  • RIBA (for architects)
  • Trade associations relevant to your industry
  • Chambers of Commerce

The subscription must be to a body recognised by HMRC as relevant to your profession. Most established professional bodies qualify.

Regulatory and Licensing Fees

Fees paid to comply with regulations are allowable:

  • FCA registration fees (for financial services)
  • ICO data protection fee
  • Trade-specific licences
  • Health and safety certifications
  • Environmental compliance fees
  • Trading Standards registrations

Record-Keeping

For professional fees, keep:

  • Invoices from all professional advisers
  • Insurance policy documents and premium statements
  • Subscription renewal notices
  • Receipts for regulatory fees

Most professional fees come with clear invoices, making record-keeping straightforward. With Accounted, forward invoices to Penny and she'll categorise them correctly.

Common Mistakes

Not claiming accountancy fees. Every sole trader who uses an accountant can claim the fee. Don't forget it.

Claiming personal legal fees. A dispute with your neighbour is not a business expense, even if you're self-employed.

Mixing up capital and revenue legal costs. Legal fees for buying property or a business are capital, not revenue.

Forgetting insurance renewals. If your insurance auto-renews by direct debit, make sure it's being recorded as an expense.
