Sole trader accountant — FAQs
What does a sole trader accountant do?
A sole trader accountant prepares and files your annual self-assessment tax return, advises on allowable business expenses, registers and manages your VAT returns if applicable, and advises on whether and when incorporating to a limited company makes sense. For growing sole traders, they also handle bookkeeping and year-round tax planning.
Do sole traders need an accountant?
Not legally — HMRC's online service allows self-filing. But most sole traders with income above £30,000–£40,000, VAT registration, or any complexity (vehicles, home office, equipment, employees) benefit from specialist help. The risk of under-claiming expenses or missing a VAT registration deadline typically costs more than the accountant.
How much does a sole trader accountant cost?
At RR Accountants, sole trader accountancy starts from £100 per month for straightforward businesses. A self-assessment-only service (no ongoing monthly engagement) starts from £200 as a one-off. Exact fees confirmed in writing after your discovery call.
When should a sole trader incorporate to a limited company?
There is no single rule, but common triggers include: profit consistently above £30,000–£40,000 (where corporation tax rates can be more efficient than income tax); planning to take on employees; wanting to separate personal and business liability; or needing to retain profits in the business. The decision should be modelled, not made generically. We assess the sole trader vs limited company question at every ACR for growing clients.
What expenses can a sole trader claim?
Common allowable expenses for sole traders include: office costs, travel and vehicles (business proportion), professional subscriptions, phone and internet (business proportion), marketing, professional fees (accountancy), training directly related to the business, and equipment. Each category has specific rules on what qualifies. We review every sole trader client's expense position at onboarding.
