If you're a self-employed subcontractor in construction, contractors deduct 20% from your labour before you're paid and send it to HMRC. Here's the thing that scheme guarantees: 20% off the top ignores your personal allowance, your van, your tools and every other cost — so you've almost certainly overpaid, and there's a refund waiting once you file.
We do CIS subcontractor returns all day. We track your deduction statements through the year, claim your vehicle, tools, PPE and everything else, file early so your refund lands fast, and make sure you're registered so contractors take 20% rather than 30%. Four-figure refunds are the norm, not the exception.
