FAQ

How much does a self-employed accountant cost in the UK?

If your question isn't here, email info@registerselfemployed.co.uk.

How much does a self-employed accountant cost in the UK?

UK accountants for self-employed people start from around £22/month, which typically covers your annual Self-Assessment filing, basic bookkeeping help, and a year-end tax review. Add-ons: bookkeeping if you don't want to do it (~£30-50/mo), MTD-compliant software (~£10/mo if your accountant doesn't include it), VAT returns if you're VAT-registered (~£25-40/mo). Annual one-off Self-Assessment-only services start from around £150 per year for very simple cases.

How long does HMRC take to send my UTR?

Usually 10-15 working days from when you submit the online registration. The activation code for the Self Assessment online service comes separately, also by post.

Can I file Self Assessment without an accountant?

Yes. Many sole traders under £20K-£25K turnover file their own. The HMRC online tool walks you through it. Above that, an accountant typically pays for themselves through claimed expenses.

What's the difference between sole trader and limited company?

A sole trader IS the business — your profits are your income, you have unlimited liability. A limited company is a separate legal entity that you're a director and shareholder of. Limited companies often save tax above £50K-£60K profit but add complexity.

When do I pay my first tax bill?

31 January following the tax year. So if you start in 2025/26, your first Self Assessment is due by 31 January 2027. If your bill is over £1,000, you'll also pay 50% toward next year on the same day.
