CIS Tax Is Complicated โ€” Your Accountant Shouldn't Be

Whether you're a sole trader subbie or running a team of 50, getting CIS wrong costs you money and can land you in serious trouble with HMRC.

CIS Deductions Eating Your Cash Flow

Having 20% or 30% deducted from every payment hurts. If you qualify for gross payment status, you could keep 100% of your earnings and manage tax on your own terms.

Late CIS Returns Mean Penalties

Miss your monthly CIS return deadline and HMRC charges ยฃ100 per month, per return. That adds up fast โ€” and triggers further scrutiny of your business.

Subcontractor Verification Headaches

Every subcontractor must be verified with HMRC before you pay them. Get it wrong and you're liable for the tax that should have been deducted.

Employment Status Uncertainty

IR35, deemed employment, worker status โ€” HMRC is cracking down on construction businesses that misclassify workers. The penalties for getting this wrong are severe.

Domestic Reverse Charge Confusion

The VAT reverse charge for construction services catches out contractors every day. Apply it wrong and you face VAT assessments, penalties, and cash flow chaos.

No Time for Paperwork

You're on site from 6am. The last thing you want is to spend evenings sorting receipts and chasing invoices. But HMRC expects proper records.

Frequently Asked Questions

CIS is a tax deduction scheme where contractors deduct money from subcontractor payments and pass it to HMRC. The standard deduction rate is 20% for registered subcontractors, 30% for unregistered subcontractors, and 0% for those with gross payment status. These deductions count as advance payments of your tax bill.

You need to meet three tests: a turnover test (ยฃ30,000+ net for sole traders over 12 months), a compliance test (all tax returns filed and payments up to date), and a business test (you must operate through a UK bank account). We assess your eligibility, prepare the application, and handle all HMRC communication.

It depends on your earnings and deduction rate. A subcontractor earning ยฃ50,000 with 20% deductions would have ยฃ10,000 deducted โ€” if your actual tax liability is lower, the difference is refunded. We've claimed over ยฃ2.1 million in CIS refunds for our clients. We calculate your exact position for free.

HMRC charges ยฃ100 for each month (or part month) that a return is late, up to 12 months. After 12 months, additional penalties based on the amount of CIS deducted can apply. For a contractor with 10 subcontractors, one late return can quickly cost over ยฃ1,000. We never miss deadlines.

It depends on your turnover, profit level, and personal circumstances. Generally, once your profits exceed ยฃ40,000โ€“ยฃ50,000, a limited company structure becomes more tax-efficient. We run the numbers for your specific situation and advise you on the best structure, including the CIS implications of incorporation.

Yes. Our unique business growth programme connects new clients with our existing customer base of 500+ construction businesses. Electricians meet plumbers, plumbers meet builders, builders meet developers. We actively facilitate introductions that lead to real work.

You must keep records of all payments to subcontractors, verification details, CIS deduction statements, invoices, bank statements, and any written contracts. Records must be kept for at least 3 years after the end of the tax year they relate to. We set up simple systems so record-keeping takes minutes, not hours.
