Short answer: You can run a simple sole trader business without an accountant, but the decision changes when your records grow, deadlines get closer, expenses are unclear or MTD becomes relevant. A good first conversation should focus on what you need help with, not just the price of a tax return.

What to prepare before the first call

  • Sales invoices, platform income, bank statements and cash income records.
  • Receipts for tools, software, mileage, home working, insurance and professional costs.
  • Previous Self Assessment returns or HMRC notices if you have them.
  • A list of worries: expenses, MTD, VAT, deadlines, software or business structure.

Where an accountant may add value

  • Setting up bookkeeping categories so you are not guessing at year end.
  • Reviewing expense treatment before you submit a return.
  • Estimating tax so you can plan cash flow.
  • Helping you decide whether software is worth the cost.

When DIY may still be reasonable

  • Very low transaction volume.
  • Clear records and no VAT, payroll, property income or company questions.
  • You are confident using official guidance and checking deadlines.
  • You understand that you remain responsible for the return you submit.

What to send before an accountant quotes

Send a short summary of your business type, turnover band, deadlines, software, current record quality and the decision you are trying to make. This helps the accountant quote for the real work rather than a vague label.

FAQs

Is an accountant compulsory for sole traders

No, but support may be worthwhile if the cost is outweighed by saved time, confidence or reduced risk of errors.

Can a bookkeeper be enough

Sometimes. A bookkeeper may organise records while an accountant handles tax return and advice questions.

What should I ask about fees

Ask whether bookkeeping cleanup, software setup, MTD support and deadline work are included or extra.
