CIS take-home on £175/day in 2025-26
On £175/day, your annual gross is £42,000 (assuming 240 working days). Each week your contractor deducts 20% CIS, which amounts to £175/week, leaving you with £700/week in your account.
But the 20% CIS is only an advance tax payment. Your actual annual tax liability is £5,886 income tax plus £1,945 in self-employed NI (Class 2 and 4), totalling £7,831. Over the year HMRC receives £8,400 from your CIS deductions, so at year-end you should receive a refund of approximately £569.
Your true annual take-home, after settling all taxes, is £34,169 (£2,847/month, £657/week), giving an effective tax rate of 18.65%. Remember this assumes no business expenses; in reality, tools, vehicle costs, and PPE can significantly reduce your income tax bill.

Do I need to file a Self Assessment tax return as a CIS subcontractor?
All CIS subcontractors must file a Self Assessment tax return each year by 31 January. This is how HMRC reconciles the 20% CIS deductions made by your contractor against your actual tax liability. On £175/day (£42,000/year gross), you would report your income, claim allowable business expenses (tools, vehicle, PPE, insurance), and either receive a refund or pay any shortfall. Failure to file results in automatic penalties starting at £100.
What business expenses can a £175/day CIS worker claim?
CIS subcontractors can deduct allowable business expenses from their taxable income before Self Assessment, reducing their income tax bill. Common deductible expenses include: tools and equipment (or capital allowances for larger items), vehicle costs (fuel, insurance, servicing, or the flat-rate mileage alternative of 45p/mile for the first 10,000 miles), PPE and safety equipment, public liability insurance, professional subscriptions, and a proportion of phone costs. On £42,000/year, every £1,000 of legitimate expenses reduces income tax by £200 at basic rate, increasing your true annual net beyond £34,169.
