Can I claim my accountant's fees as a business expense?

Yes — accountant's fees are fully deductible as a business expense. HMRC allows costs incurred wholly and exclusively in connection with your business, and professional fees paid to an accountant for preparing your business accounts, filing your Self Assessment return, and providing business tax advice all qualify. This includes: preparation of annual accounts, Self Assessment tax return preparation and submission, bookkeeping services, payroll services (if you have staff), and business tax advisory work. However, accountant fees related to personal tax matters that are entirely separate from your business (e.g. advice purely on personal investments or a second property you don't rent out) are not deductible. Claim accountant fees under 'Accountancy, legal and other professional fees' on your SA103 return.
