Do I Need an Accountant as a UK Tradesperson?

ByTradeStack HQ

It’s one of the most common questions sole trader tradespeople ask: do I actually need an accountant, or can I just do it myself with software? The honest answer is it depends on where your business is and how complicated your finances are. This guide gives you a straight verdict on when an accountant earns their fee, when software alone is genuinely sufficient, and what to look for if you do hire one.

What Does an Accountant Actually Do for a Tradesperson?

A good accountant who works with trade businesses will typically:

  • Prepare and submit your Self Assessment tax return – or MTD final declaration from 2026 onwards
  • Make sure you’re claiming every allowable expense correctly
  • Review your quarterly MTD updates before submission
  • Advise on VAT registration timing and the best scheme for your business
  • Help you decide when and whether to incorporate as a limited company
  • Handle payroll and CIS returns if you have employees or subcontractors
  • Advise on pension contributions and year-end tax planning
  • Deal with HMRC on your behalf if there’s ever an enquiry or dispute

A good accountant doesn’t just file your return – they actively reduce your tax bill by knowing what you can claim and planning your finances intelligently throughout the year. The fee pays for itself in most cases.

When You Probably Don’t Need an Accountant

There are situations where accounting software alone is genuinely sufficient:

  • You’re just starting out with low turnover and very simple finances
  • Your only income is from self-employment with no property income or investments
  • You have no employees, no subcontractors, and no VAT registration
  • You’re comfortable using accounting software and keeping records up to date
  • Your expenses are straightforward – materials, van, tools, phone

In this situation, FreeAgent or QuickBooks can handle your bookkeeping, calculate your tax position, and submit your Self Assessment or MTD updates without professional help. The software cost is typically £10–£15 per month versus £500–£1,500 per year for an accountant. A sole trader electrician just starting out turning over £30,000 with simple expenses and no staff can manage perfectly well with software alone, at least in the early years.

When an Accountant Is Worth It

Your turnover is growing

Once you’re turning over £40,000–£50,000 or more, the tax saving from proper planning – pension contributions, timing of expenses, VAT scheme selection, incorporation advice – typically outweighs the accountant’s fee several times over. A tradesperson paying £800 per year for an accountant who saves them £2,000 in tax is getting an excellent return.

You’re approaching VAT registration

The VAT registration threshold is currently £90,000. As you approach it, the choice of VAT scheme matters – the Flat Rate Scheme can be significantly more or less advantageous than standard VAT depending on your costs. Getting this wrong costs money. An accountant advises on the right choice and handles registration and returns.

You have employees or subcontractors

PAYE payroll, CIS deductions, employer’s NI, pension auto-enrolment, monthly CIS returns – each is a compliance obligation with penalties for getting it wrong. An accountant who handles this gives you confidence it’s correct and frees up your time to be on the tools.

You’re thinking about incorporating

The decision to move from sole trader to limited company has significant tax, legal, and practical implications. An accountant models the numbers for your specific situation and tells you whether the switch makes sense. Getting this wrong – incorporating too early or setting up the salary and dividend split incorrectly – costs more than the advice.

You’ve received anything unexpected from HMRC

Letters about enquiries, compliance checks, incorrect tax codes, penalties – anything from HMRC that isn’t a routine annual reminder is worth discussing with an accountant. They deal with HMRC regularly and know how to respond. Most sole traders don’t.

Making Tax Digital now applies to you

If your turnover is over £50,000 and MTD for Income Tax applies, having an accountant review your quarterly updates before submission is a sensible safeguard – especially in the first year when the process is new. They can catch categorisation errors before they become problems. See our full guide on what Making Tax Digital means for tradespeople.

How Much Does an Accountant Cost?

  • Self Assessment return only: £200–£500 per year
  • Full bookkeeping review and Self Assessment: £500–£1,000 per year
  • Full service including payroll, CIS, VAT: £1,000–£2,500+ per year
  • Limited company accounts and corporation tax: £1,000–£2,000+ per year

Prices vary by location – accountants in London typically charge more than those in the North or Scotland. Many offer fixed monthly fees rather than annual bills, which makes budgeting easier. The accountant’s fee is itself a claimable business expense, which reduces the real cost once you factor in the tax relief.

What to Look For in an Accountant

  • Experience with self-employed tradespeople – they should understand CIS, van expenses, tool claims, and the practical realities of a trade business without you needing to explain it all
  • Familiarity with your accounting software – if you’re using Xero or FreeAgent, your accountant should know it well. Working on the same platform means they can access your records directly
  • A fixed monthly fee – predictable costs are easier to manage than surprise bills
  • Responsiveness – they should answer questions within a day or two, not weeks later
  • Qualified status – look for ACCA, ACA, or CIMA qualified accountants or firms regulated by a professional body

Word of mouth from other tradespeople in your area is often the best way to find a good one. Ask a fellow tradesperson who they use and whether they’d recommend them.

Software and Accountant: Better Together

It’s not an either/or choice. Most tradespeople who use an accountant also use accounting software – the software handles day-to-day bookkeeping and the accountant reviews, advises, and submits. The software keeps your records accurate and current throughout the year. The accountant uses those records to minimise your tax bill, handle compliance, and give you advice software can’t. Under Making Tax Digital, this combination becomes the standard approach for any sole trader with meaningful turnover.

The Bottom Line

If you’re just starting out with simple finances and you’re comfortable with software, you can manage without an accountant. Once your turnover grows, once you’ve got employees or subcontractors, once VAT registration is on the horizon – the accountant’s fee pays for itself easily and the peace of mind is worth it on its own. The tradespeople who tend to regret not having an accountant are the ones who hit a complicated situation without professional support. Getting advice before you need it urgently is always cheaper than getting it after.

Frequently Asked Questions

Do I need an accountant as a sole trader tradesperson?

Not necessarily in the early years if your finances are simple. A sole trader with straightforward income, no staff or subcontractors, no VAT registration, and turnover under £30,000–£40,000 can manage with accounting software alone. But once your turnover grows, once VAT registration approaches, once you have employees or CIS obligations, or once you’re considering incorporating – an accountant’s fee quickly pays for itself through tax savings, compliance confidence, and advice you wouldn’t get from software.

How much does an accountant cost for a tradesperson?

For a sole trader tradesperson with straightforward finances: Self Assessment return only typically costs £200–£500 per year; full bookkeeping review plus Self Assessment costs £500–£1,000 per year; full service including payroll, CIS, and VAT runs £1,000–£2,500+ per year. Prices vary by region – London accountants typically charge more. Note that the accountant’s fee is itself a claimable business expense, reducing the real cost once tax relief is factored in.

At what turnover should a tradesperson get an accountant?

There’s no hard rule, but most trade business accountants suggest it becomes clearly worthwhile once you’re consistently turning over £40,000–£50,000 or more. At that level, the tax savings from proper planning – pension contributions, timing of expenses, VAT scheme selection – typically outweigh the accountant’s fee several times over. Below that threshold, good accounting software may be sufficient if your finances are straightforward.

Can I do my own tax return as a self-employed tradesperson?

Yes, you can file your own Self Assessment tax return or MTD quarterly updates if your finances are straightforward. HMRC’s online systems accept self-filed returns and MTD-compatible accounting software like FreeAgent, QuickBooks, or Xero can submit quarterly updates directly to HMRC without an accountant. The main risk of self-filing is missing allowable expenses you could have claimed or making errors that trigger penalties – which is why many tradespeople prefer an accountant to review at least annually even if they do the bookkeeping themselves.

What’s the difference between an accountant and accounting software?

Accounting software (like Xero, QuickBooks, or FreeAgent) handles your day-to-day record-keeping, categorises transactions, calculates your tax position, and submits returns to HMRC. An accountant provides professional advice, reviews your records for errors and missed expenses, advises on tax planning decisions software can’t make, and handles complex situations like VAT registration, CIS, payroll, and HMRC enquiries. The best setup is typically both together – software for ongoing bookkeeping, accountant for annual review and strategic advice.

What should I look for in an accountant as a tradesperson?

Look for: specific experience with self-employed tradespeople (they should understand CIS, van expenses, and tool claims without explanation); familiarity with your accounting software so they can access records directly; a fixed monthly fee for predictable costs; responsiveness within a day or two; and ACCA, ACA, or CIMA qualified status. Word of mouth from other tradespeople in your area is usually the best way to find a good one – ask who they use and whether they’d recommend them.
