Southampton has one of the south coast's most active construction trade communities, anchored by the substantial Mayflower Park and Royal Pier Waterfront regeneration, the long-running Ocean Village marina development, the substantial WestQuay refurbishment and adjacent residential blocks, the Solent docks expansion (one of the UK's largest container ports), the steady stream of new-build residential apartment blocks across SO14 and SO15, and the wider Hampshire commercial construction economy. The Construction Industry Scheme is one of the most common reasons Southampton subcontractors overpay tax every year. Main contractors deduct 20 per cent (or 30 per cent if you are not verified) from every payment they make to you, regardless of your actual expenses or final tax position. By the end of the tax year the deductions have usually overshot your real tax liability by a significant margin, and a properly-prepared Self-Assessment unlocks a refund of typically £1,500 to £5,000 for most Southampton subcontractors.

📅 Get Your Free Backdated CIS ReviewReal Client Story
Client J is a self-employed Gas Safe plumber based in Southampton, working through CIS for several main contractors on Royal Pier Waterfront residential blocks, Ocean Village marina developments and WestQuay-adjacent fit-outs. When he came to us his expense records were essentially a folder of receipts in his van, a memory of which jobs he had done and a previous accountant who had been filing a basic Self-Assessment without actively reviewing his expense position. His CIS deductions over the year had totalled around £7,300 against gross earnings of £36,500.
We rebuilt his records for the year and captured every legitimate expense: van and fuel costs across multiple sites, Gas Safe plumber-specific tools and equipment (including a new press tool and a new pipe freezer mid-year), PPE and safety boots, his Gas Safe registration renewal, ACS reassessment fees, his CSCS card renewal and an unvented hot water systems certification, mobile and admin costs, work clothing, materials he had purchased himself for several jobs, and a reasonable home-office proportion. We also moved him onto a simple receipt-capture app for going forward.
Outcome: CIS refund of £4,700, filed within 9 days of the 6 April tax year end and received from HMRC five weeks later. Client J now has a system that captures receipts as they happen and gives him a clear running view of his refund position throughout the year.
