    If you’re a CIS subcontractor, you already know the pain:

    • Deductions feel random

    • Cashflow swings month to month

    • VAT reverse charge adds confusion

    • And HMRC letters never arrive at a “good time”

    Perpetual Accountancy helps CIS subcontractors stay compliant, keep more profit, and avoid surprises — using Xero + WhatsApp to keep everything simple.

    Who this is for

    We support CIS subcontractors working as:

    • Sole traders

    • Limited companies

    • Partnerships

    • Trades across construction: groundworks, electricians, plumbers, joiners, plasterers, bricklayers, roofing, carpentry, plant operators, decorators, steel/fabrication and more.


    Common CIS problems we fix

    If any of these sound familiar, you’re in the right place:

    ✅ 20% or 30% CIS deductions and you’re not sure why
    ✅ Contractor deducted CIS on materials or even VAT
    ✅ Missing CIS deduction statements
    ✅ You’re always due a refund but it takes forever
    ✅ You’re VAT registered and reverse charge is confusing
    ✅ You don’t know what to keep aside for tax
    ✅ Your books are “a bag of receipts” (no judgement)
    ✅ HMRC penalties, late filing, or messy records

    FAQs (CIS Subcontractors)

    Why am I being deducted 30%?
    Usually because you’re not verified or registered correctly with the contractor/HMRC. We help fix the status and reduce deductions going forward.

    Is CIS taken off the whole invoice?
    Not usually. Deductions should typically apply to labour (and certain other costs), not direct materials, and VAT is handled separately. We check your invoices and contractor statements for errors.

    How do I claim CIS tax back?
    Sole traders claim CIS deductions through Self Assessment. Limited companies typically offset CIS deductions against payroll liabilities. We handle the process and keep the evidence tidy.

    Do I need to be VAT registered?
    It depends on turnover and your circumstances. If you are VAT registered, reverse charge may apply and we’ll make sure it’s treated correctly.

    Should I go limited company?
    Sometimes yes — but not always. We’ll compare your expected profit, tax position, CIS deductions, and cashflow before recommending anything.
