Accounting for Tradespeople: Plumbers, Electricians and Builders

Introduction: Building a Solid Financial Foundation

For plumbers, electricians, builders, and other skilled tradespeople across the UK, managing finances can feel like a complex job in itself. Beyond mastering your craft, understanding the intricacies of tax, expenses, and regulatory schemes like the Construction Industry Scheme (CIS) and Domestic Reverse Charge (DRC) VAT is essential for business success. This comprehensive guide will break down the key accounting considerations for tradespeople, helping you keep more of your hard-earned money and stay compliant with HMRC.

The Construction Industry Scheme (CIS): What You Need to Know

The CIS is a special scheme that applies to most construction work in the UK. If you're a contractor, you must deduct money from payments you make to subcontractors and pay it to HMRC. If you're a subcontractor, contractors will deduct money from your payments. This deducted money counts as advance payments towards your tax and National Insurance bill.

Are You a Contractor or Subcontractor?

You're a contractor if you pay subcontractors for construction work or if your business spends more than £1 million on construction in a 12-month period. You're a subcontractor if you do construction work for a contractor.

CIS Deduction Rates (2026/27)

The standard deduction rate for CIS is 20%. However, if you have 'gross payment status', contractors will pay you in full without any deductions. To get gross payment status, you must apply to HMRC and meet certain conditions, including having a good tax compliance record.

Benefits of CIS Registration

• Lower Deduction Rate: Registered subcontractors pay 20% instead of 30%.
• Gross Payment Status Eligibility: With a good tax history, you can apply to receive payments without deductions.
• Easier Tax Reconciliation: Deductions count towards your annual tax and National Insurance bill, simplifying year-end calculations.

VAT and the Domestic Reverse Charge (DRC) for Building Services

As a tradesperson, understanding VAT is crucial, especially with the introduction of the Domestic Reverse Charge (DRC) for building and construction services. The standard VAT registration threshold for 2026/27 remains at £90,000 [2]. If your VAT-taxable turnover exceeds this, you must register for VAT.

What is the Domestic Reverse Charge (DRC)?

The DRC means that the customer receiving the construction service, rather than the supplier, has to account for the VAT. This applies to most building and construction services supplied between VAT-registered businesses in the UK. It's designed to combat VAT fraud in the construction sector.

Key DRC Considerations:

• Applies to standard and reduced-rate VAT services.
• Both contractor and subcontractor must be VAT registered.
• Does not apply to services supplied to end-users or intermediaries connected to end-users.
• Must be clearly stated on your invoices.

Maximising Allowable Expenses: Reducing Your Taxable Income

One of the most effective ways for tradespeople to reduce their tax bill is by accurately tracking and claiming all allowable business expenses. HMRC allows you to deduct costs that are 'wholly and exclusively' for business purposes. Keep meticulous records of everything!

Common Allowable Expenses for Tradespeople:

• Tools and Equipment: Purchase, hire, repair, and insurance of tools and equipment.
• Materials: All raw materials used in your work (e.g., pipes, wires, timber, fittings).
• Vehicle Costs: Fuel, insurance, repairs, servicing, and vehicle excise duty for business use. You can claim actual costs or use simplified mileage rates.
• Travel Expenses: Public transport, accommodation, and subsistence costs for business trips.
• Clothing: Protective clothing, uniforms, and branded workwear (not everyday clothing).
• Training: Courses and qualifications directly related to improving your trade skills.
• Office Costs: Stationery, postage, phone, internet, and software subscriptions.
• Home Office: If you work from home, you can claim a proportion of household bills or use the simplified flat rate.
• Insurance: Public liability, professional indemnity, and tool insurance.
• Professional Fees: Accountant fees, legal advice, and trade association memberships.
• Marketing: Website costs, advertising, and business cards.

Income Tax and National Insurance: 2026/27 Overview

Understanding your Income Tax and National Insurance obligations is fundamental. For the 2026/27 tax year, the Personal Allowance remains at £12,570 [1]. This is the amount of income you can earn before paying any Income Tax.

Note: Your Personal Allowance is reduced by £1 for every £2 of income over £100,000.

National Insurance Contributions (NICs)

If you're self-employed, you'll typically pay Class 2 and Class 4 National Insurance Contributions. The rates and thresholds are subject to change, but generally, Class 2 NICs are a flat weekly rate (if profits are above a certain threshold), and Class 4 NICs are a percentage of your profits above a lower profits limit.

Choosing the Best Accounting Software for Tradespeople

The right accounting software can significantly simplify your financial management, ensuring compliance and saving you valuable time. For tradespeople, key features to look for include robust CIS handling, MTD for VAT compliance, easy expense tracking, and invoicing capabilities.
