If you are a sole trader in the UK, you need an accountant who can prepare your accounts, file your Self Assessment tax return, and keep you compliant with HMRC throughout the year. The question is how much that should cost.
According to industry data, sole traders in the UK typically pay between £300 and £1,200 per year for professional accounting services. But not every provider charges the same, and some offer significantly better value than others.
We compared five options available in 2026 and ranked them by annual cost. All prices listed here are taken directly from each provider's public website.
Sole Trader Accountancy Services: Price Comparison
All prices sourced from each provider's public website as of June 2026. VAT applies where stated. Actual costs may vary based on complexity and turnover.
1. Taxez: From £199/Year
Taxez is a UK online accountancy firm run by Chartered Accountants, currently serving over 2,000 clients with a 5-star rating. The sole trader Business Package starts at £199 per year and includes everything a sole trader needs to stay compliant.
Here is how the pricing scales with turnover:
Tax return preparation and HMRC submission
A dedicated Chartered Accountant assigned to your account
Unlimited advice and support throughout the year, at no extra cost
Tax efficiency guidance to actively reduce your bill
All tax allowances reviewed and claimed
Deadline reminders for filing and payment dates
Secure document sharing portal
No surprise fees
At £199 per year for smaller sole traders, this is the lowest annual price of any professional accountancy service on this list. And unlike some providers, the price includes year-round access to your accountant, not just a one-off filing.
Taxez also offers a separate Personal Self Assessment service from £59 for individuals who are not running a business but need to file a return (for example, someone with a salary plus investment income).
2. Crunch: From £25.50+VAT/Month (£306+VAT/Year)
Crunch is an established online accountancy platform that combines accounting software with professional accountancy support. Their Sole Trader Pro plan is priced at £25.50+VAT per month, which works out to approximately £306+VAT per year.
Crunch has been operating since 2009 and holds a 4.6 out of 5 rating on Trustpilot. Their platform includes their own accounting software alongside accountant support.

4. Sleek: From £60/Month (£720/Year)
Sleek is a global accounting platform that offers UK sole trader accounting from £60 per month, which comes to £720 per year. Their pricing includes a dedicated accountant, bookkeeping, tax filing, and compliance support.

5. Traditional High-Street Accountants: £300 to £1,200/Year
For sole traders using a local, high-street accountant, annual costs typically range from £300 to £1,200 per year depending on the complexity of the business and the level of service. This figure comes from industry-wide pricing data published in 2026.
The main advantage of a local firm is face-to-face meetings. The trade-off is higher pricing, driven by the overhead costs of maintaining a physical office, which are passed on to the client.
What to Look For When Choosing a Sole Trader Accountant
Not every accountancy service covers the same ground. Before you decide, here is what a sole trader should expect as standard:
Accounts preparation. HMRC expects sole traders to keep accurate records. Your service should handle this, not leave it to you.
Self Assessment filing. Your tax return needs to be prepared, checked, and submitted to HMRC by the 31 January deadline.
Expense guidance. Claiming the right allowable expenses is where a good accountant saves you more than their fee.
Year-round access. Tax questions do not only come up in January. Being able to reach your accountant throughout the year matters.
MTD readiness. From April 2026, sole traders earning over £50,000 must comply with Making Tax Digital.
Taxez includes all of the above at £199 per year. That is accounts, tax return, a dedicated Chartered Accountant, unlimited year-round advice, and no hidden fees. When every other comparable service on this list starts at £300 or more per year for a similar scope, the value speaks for itself.
Common Questions
Is £199 per year really all-inclusive for sole traders?
Yes. The Taxez Business Package includes accounts preparation, tax return filing, a dedicated Chartered Accountant, unlimited advice, deadline reminders, and a secure document portal. There are no hourly charges. Full pricing is on the Taxez website.
What if I am not a sole trader but still need to file?
If you are employed but receive dividends, interest, or rental income, Taxez offers a Personal Self Assessment from £59. This is a separate service from the sole trader Business Package.
Should I just go with the cheapest option?
That depends on what is included. A lower headline price that does not cover accounts preparation or year-round advice may end up costing more in missed deductions or last-minute fees. Always compare what is included, not just the number.
