If you run a trade business in the UK, you already know the numbers game is different from other industries. You deal with the Construction Industry Scheme (CIS), fluctuating material costs, subcontractor payments, and VAT that can hit you hard if you are not careful. A general accountant who handles coffee shops and ecommerce stores might not know the specific rules that apply to you.
That is where a specialist accountant for tradespeople makes a real difference. They understand the sector, the forms, and the tax reliefs available to you. This article explains what a trade-focused accountant does, why you need one, and how to choose the right firm.
What Does an Accountant for Tradespeople Actually Do?
A standard accountant files your tax return and tells you your corporation tax bill. A specialist does much more. They work through the specific compliance and planning challenges that tradespeople face every day.
CIS Compliance and Deductions
The Construction Industry Scheme is the biggest difference between a trade business and most other small companies. If you are a subcontractor, your clients deduct 20% (or 30% if you are not registered for gross payment) from your invoices and send it directly to HMRC. That money sits in your HMRC account until you file your return or claim it back.
Your accountant should track these deductions throughout the year. They need to reconcile them against your tax and National Insurance liabilities. If you are a contractor who employs subcontractors, your accountant must file monthly CIS300 returns and issue CIS25 deduction statements to each subcontractor. Miss a deadline and you face penalties starting at £100 per month per return.
An experienced accountant for tradespeople will also advise you on whether applying for gross payment status makes sense. Gross payment means clients pay you in full without deducting CIS. To qualify, you must meet HMRC's turnover, compliance, and business tests. Your accountant can check your eligibility and help you apply using the online service or form CIS301.
VAT Planning for Tradespeople
VAT is a recurring headache for many trade businesses. The registration threshold is £90,000 in a rolling 12-month period. But many tradespeople hit that threshold quickly, especially during busy periods.
Your accountant should help you decide between the standard VAT scheme (charge 20%, reclaim input tax) and the Flat Rate Scheme (charge 20% to customers but pay a fixed percentage to HMRC based on your trade). For a limited cost trader, the flat rate is 16.5%. For most trades, the flat rate is lower than that. A plumber on the Flat Rate Scheme pays 10.5% (or 16.5% if limited cost). An electrician pays 10.5% or 14.5% depending on their specific trade category. These percentages make a big difference to your bottom line.
Your accountant should also review whether you are better off on the Cash Accounting Scheme (pay VAT when your customers pay you) or the Annual Accounting Scheme (fewer returns, fixed payments). If you regularly work with VAT-registered clients, standard VAT might be better because you can reclaim VAT on materials, tools, and van costs.
IR35 and Your Limited Company
Many tradespeople work through their own limited company, especially if they contract for larger developers or public sector clients. If you do, IR35 applies. The off-payroll working rules mean the client (if they are medium or large) decides your employment status and issues a Status Determination Statement (SDS).
If you are inside IR35, your limited company pays employer NI (13.8%) and the Apprenticeship Levy (0.5% on earnings above £3 million) on your deemed employment income. You also pay employee NI and income tax through payroll. The dividend route disappears. Your accountant should model both scenarios before you take a contract.
If you are outside IR35, your accountant should help you prepare a robust contract and working practices review. They should also keep records of your working arrangements in case HMRC opens an enquiry.
Year-End Tax Planning
A good accountant does not just prepare your year-end accounts. They plan ahead. For a trade business, that means thinking about capital allowances. If you buy a new van, you can claim 100% first-year allowances on zero-emission vans (up to £85,000 for cars, but vans have no cap if zero-emission). For a standard van, you claim the Annual Investment Allowance (AIA) at £1 million per year. That means you can deduct the full cost of a £35,000 van from your taxable profits in the year you buy it.
Your accountant should also review your structure. Are you better off as a sole trader or a limited company? The answer depends on your profit level, your personal tax position, and whether you want to take dividends or salary. For a tradesperson earning £60,000 profit, a limited company often saves thousands in tax compared to being a sole trader. But that saving comes with extra admin and filing requirements. Your accountant should run the numbers for your specific situation.
Why Not Just Use a General Accountant?
A general accountant can handle your books. They can file your self assessment return and your corporation tax return. But they will likely miss the industry-specific savings and compliance points that a specialist accountant for tradespeople knows by instinct.
For example, a general accountant might not know that you can claim CIS deductions suffered against your tax liability even if you are a sole trader. They might not know that the Flat Rate Scheme percentage for a "construction" business is different from a "plumbing" business. They might not know that HMRC expects you to keep a record of your CIS deductions using form CIS36 (annual statement) or that you need to report them on your SA103 (self-employment pages) specifically at box 18.
These details matter. Get them wrong and you overpay tax or face penalties. Get them right and you keep more of your hard-earned money.
What to Look for in an Accountant for Tradespeople
Not all accountants who claim to work with tradespeople are the same. Here are the specific things to check before you appoint one.
ICAEW or ACCA Qualification
Look for a firm that is ICAEW or ACCA qualified. These are the two main chartered accountancy bodies in the UK. They require ongoing professional development and adherence to strict ethical standards. Holloway Davies are ICAEW qualified, which means our team meets those standards. It is a mark of quality and accountability.
Experience with CIS and VAT
Ask the accountant how many trade clients they have. Ask them to explain the CIS deduction process from start to finish. Ask them how they handle a subcontractor who is not registered for gross payment. If they stumble or give vague answers, move on.
Software and Technology
Most tradespeople use bookkeeping software like Xero, QuickBooks, or FreeAgent. Your accountant should be comfortable with these platforms. They should also use tools like Dext or Hubdoc to automate receipt capture. If you are still doing manual bookkeeping, your accountant should be able to recommend a system that works for you.
Proactive Advice, Not Just Compliance
A good accountant does not just wait for your year-end. They contact you during the year to discuss tax planning, VAT changes, and business growth. They send reminders for VAT returns, CIS returns, and payroll deadlines. They flag issues before they become problems.
How Much Does an Accountant for Tradespeople Cost?
Fees vary depending on the complexity of your business and the services you need. A sole trader with simple CIS deductions and one VAT return per quarter might pay £100 to £150 per month. A limited company with multiple subcontractors, payroll, and quarterly VAT returns might pay £200 to £400 per month. Some firms charge a fixed monthly fee, others charge per return.
Always ask for a clear breakdown of what is included. Does the fee cover your year-end accounts, corporation tax return, self assessment, VAT returns, CIS returns, and payroll? Or are those charged separately? Does it include unlimited advice or is that an extra cost? Get it in writing before you sign up.
When Should You Switch Accountants?
If your current accountant does not understand CIS, does not advise on VAT schemes, or only contacts you once a year, it is time to switch. You should also switch if you have grown from a sole trader to a limited company and your accountant has not suggested a structure review.
Switching accountants is straightforward. Your new accountant will write to your old one to request your records. They will handle the professional clearance process. You do not need to do much beyond signing an authority letter. Most switches happen within a few weeks.
Case Study: A Plumber in Manchester
Let us use a real example. A plumber in Manchester, trading as a limited company, turns over £120,000 per year. He works for a mix of domestic clients and a large developer. He has one van, one employee, and two regular subcontractors.
His old general accountant charged £180 per month. That covered his year-end accounts and corporation tax return. Everything else was extra: £50 per VAT return, £30 per CIS return, £40 per payroll run. He was paying over £3,000 per year in total.
He switched to a specialist accountant for tradespeople who charged £250 per month for everything: year-end, VAT, CIS, payroll, and unlimited advice. The new accountant reviewed his VAT scheme and found he was on standard VAT when the Flat Rate Scheme would save him £2,400 per year. They also advised him to claim AIA on a new van he bought, saving another £7,000 in corporation tax. The total saving was over £9,000 in the first year.
The lesson is simple. A specialist accountant pays for themselves many times over.
