Why CIS Compliance Matters
HMRC created the Construction Industry Scheme (CIS) to regulate the process of tax deduction in the construction industry, yet to numerous contractors and subcontractors, it soon becomes a nightmare. A failure to meet a deadline, or use the incorrect rate of deduction, or misunderstanding the rules, can be financially devastating. Contractors are automatically fined a minimum of £100 per return missed and this increases as mistakes are made, and subcontractors frequently miss out on valuable cash flow as they are not reclaiming what is rightfully theirs.
Why Contractors & Subcontractors Need Specialist Accountants
- Confusing CIS registration process
- Missing monthly return deadlines
- Risk of HMRC penalties and interest
- Subcontractors overpaying and struggling to claim refunds
- Managing payroll alongside CIS deductions
- Unclear understanding of cis accounting meaning
How Lanop Saves You Time & Tax
Time is money to many people in the construction business. Contractors find themselves being tugged in all directions as they handle projects, staff, and client needs while subcontractors tend to waste their precious time tracking down refund money or wading through paperwork. Time consuming tasks such as preparing returns, monitoring deductions, and responding to HMRC queries take focus away from core business activities.

FAQ
ask us
anything
Do I need a CIS accountant as a subcontractor?
Yes, because subcontractors often overpay tax without realising it. A cis accountant ensures that all allowable expenses are included, deductions are calculated correctly, and refunds are reclaimed promptly, saving you both money and stress.
How do I add CIS to my business tax account?
You must register with HMRC and add CIS to your existing business tax account through the Government Gateway system. At Lanop, we handle this entire process on your behalf to make sure your account is set up correctly from day one.
What if I miss a CIS return deadline?
HMRC fines start at £100 for a missed return and increase the longer it remains unfiled. In addition, interest can be charged on unpaid amounts. Our team prevents this risk by filing every return accurately and on time.
Can I manage CIS myself without an accountant?
It is technically possible, but risky. Errors in CIS filing can quickly lead to penalties or delays in receiving refunds. A cis accountant will not only make sure that you are compliant, but will also allow you to maximise your cash flow as well as prevent costly errors.
How long does it take to receive a CIS refund?
The refund process usually takes 4-12 weeks, depending on the speed at which HMRC processes them. We reduce delays by ensuring your returns are accurate, filing early, and following up with HMRC regularly until payment is made.
As a subcontractor, what expenses can I claim?
You are allowed to claim the costs of tools, travel, mileage, protective clothing, insurance, and training. We ensure that all valid deductions are captured in order to minimise your taxable income and maximise your refund.
