How does CIS affect a self-employed builder's tax?
Under the Construction Industry Scheme (CIS), contractors deduct 20% from your payments and send it to HMRC. This is not extra tax — it is an advance payment. When you file your Self Assessment, CIS deductions are offset against your tax bill. If more was deducted than you owe, you get a refund. Self-employed builders pay income tax on net profit (after expenses) and Class 4 NI at 6% on profits between £12,571 and £50,270.
- CIS deductions (20%) are advance tax payments, not additional tax
- Offset CIS against your Self Assessment tax bill
- Tools, van costs, PPE, and materials are deductible
- CSCS card and training fees are claimable
- File by 31 January to claim any CIS refund
