Cardiff has one of Wales's most active construction trade communities, anchored by the substantial Central Quay regeneration around Cardiff Central station, the long-running Cardiff Bay residential and commercial pipeline, the substantial Capital Quarter commercial cluster, the Cardiff Parkway and Coal Exchange conservation trade, the steady stream of student accommodation blocks and city-centre residential apartments across CF10 and CF11, and the wider South Wales commercial construction economy. The Construction Industry Scheme is one of the most common reasons Cardiff 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. Note that Welsh-resident subcontractors are subject to Welsh Rates of Income Tax (WRIT), currently set at rates matching the rest of the UK by the Senedd, but CIS deductions and refund mechanics work the same way regardless. 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 £5,500 for most Cardiff subcontractors.

📅 Get Your Free Backdated CIS ReviewReal Client Story
Client R is a self-employed plasterer based in Cardiff, working through CIS for several main contractors on Central Quay residential blocks, Cardiff Bay waterfront developments and Capital Quarter commercial 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 £7,400 against gross earnings of £37,000.
We rebuilt his records for the year and captured every legitimate expense: van and fuel costs across multiple sites, plasterer-specific tools and equipment (including a new mixer drill and several new hawks and trowels mid-year), PPE and safety boots, his CSCS card renewal, scaffold tower training and a working-at-height refresher, 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 £4,800, filed within 9 days of the 6 April tax year end and received from HMRC five weeks later. Client R now has a system that captures receipts as they happen and gives him a clear running view of his refund position throughout the year.
