Accountant for Builders and Construction Workers

CIS, VAT and tax support for self-employed builders and small construction firms

From site work to snagging, running a building business takes serious graft—and keeping your tax sorted often ends up at the bottom of the list. But whether you’re self-employed, working under CIS, or running a small team, good accounting can save you money and hassle.

At Yorkshire Accountancy, we specialise in supporting trades. As your accountant for builders and construction professionals, we’ll help you stay compliant, keep your tax bill down, and run a financially sound construction business.

Who we help

We work with:

  • Self-employed builders and general trades
  • CIS subcontractors and contractors
  • Domestic and commercial builders
  • Limited companies and small construction firms
  • Project-based teams with employees or subbies
  • New build, renovation, and property maintenance specialists

Whether you’re laying bricks, running sites or juggling staff and suppliers—we’ll keep your accounts straight.

Self-employed construction & builder tax advice

Builders working as sole traders need to register with HMRC, track income and expenses, and file an annual return. If you’re under CIS, you’ll also be subject to tax deductions at source.

Our self-employed builder tax advice covers:

  • CIS registration (gross or net payment status)
  • Claiming all allowable expenses
  • Budgeting for tax and National Insurance
  • Preparing clean, HMRC-compliant records
  • Understanding when to incorporate
  • Claiming refunds quickly where tax has been overpaid

We’ll help you reduce tax, stay on top of deadlines, and focus on your trade.

What expenses can builders claim?

There are plenty of claimable costs in building work—but many trades leave thousands unclaimed each year.

Claimable expenses include:

  • Tools and equipment (hand tools, drills, mixers, ladders)
  • Van and transport costs (mileage or actual)
  • Fuel, maintenance, insurance and parking
  • Building materials and site supplies
  • PPE, overalls, gloves, hard hats and boots
  • Mobile phone (business portion)
  • Subcontractor and labour costs
  • Hire of skips, scaffolding, diggers or lifts
  • Trade insurance and waste carrier licences
  • Bookkeeping and accountancy support

Often-missed or lesser-known claims:

  • Cleaning workwear at home
  • Site office costs or home office admin
  • Software for estimating, quoting or job tracking
  • Trade directory subscriptions (e.g. Checkatrade)
  • Safety training and site cards (CSCS)
  • Consumables (dust sheets, tape, fixings)
  • Business use of home (if not office-based)

We’ll go through your situation line by line and help you claim safely and fairly.

CIS support for builders

If you’re working as a subcontractor under CIS, your contractor will usually deduct 20% from your payments. We’ll make sure you:

  • Register correctly for CIS
  • Track your monthly deductions
  • Submit your tax return accurately
  • Claim expenses to reduce your final bill
  • Get your refund fast
  • Avoid interest and penalties

If you’re a contractor with subcontractors, we’ll also:

  • Verify new workers
  • Submit monthly CIS returns
  • Generate subcontractor statements

Help with gross status applications if needed

Should builders go Limited?

For many builders earning £40,000+ profit, switching to a limited company can reduce tax and protect the business. We’ll help you:

  • Assess the potential tax savings
  • Decide on salary vs dividends
  • Navigate VAT and CIS rules under a company
  • Set up PAYE and pensions if needed
  • Transition smoothly from sole trader

We’ll handle the setup and take care of the ongoing admin—so you can get on with running the site.

VAT and the building/construction trade

Building work often triggers VAT issues—especially when supplying both labour and materials.

We’ll help you:

  • Register for VAT if your turnover passes £90,000
  • Apply the correct rate (standard, reduced, zero)
  • Use the Domestic Reverse Charge where required
  • Decide between flat rate and standard VAT schemes
  • Avoid penalties or double VAT charges
  • Understand VAT treatment for new builds vs renovations

We’ll also review whether voluntary registration is worth it—especially if you have high material costs.

Making Tax Digital & bookkeeping for builders

MTD now applies to all VAT-registered businesses—and will expand soon to most sole traders.

We’ll help you:

  • Set up QuickBooks or Xero (free QuickBooks licence + training included – March 2025 offer)
  • Link your invoices, receipts and bank accounts
  • Track job profitability and costs
  • Submit quarterly VAT returns under MTD rules
  • Stay organised without drowning in paperwork

Prefer spreadsheets? We’ve got a custom Google Sheets template designed for trades.
