- CIS Returns & Contractor Support
Stay compliant. Avoid penalties. Focus on the build.
The Construction Industry Scheme (CIS) comes with strict rules and monthly deadlines. Whether you're a contractor or subcontractor, we handle your CIS obligations with precision — so you can focus on delivering projects, not chasing paperwork.
What We Handle
We provide a full CIS support service tailored to construction businesses. Our service includes:
- Monthly CIS return preparation and submission to HMRC
- Verification of subcontractors and correct deduction rates
- Statement generation for subcontractor payments
- Handling HMRC correspondence and inspection support
- Integration with payroll and bookkeeping systems
- Guidance on reclaiming CIS deductions for limited companies
Whether you’re managing multiple subcontractors or just starting out, we ensure your CIS setup is accurate, efficient, and fully compliant
Why Accuracy Matters
CIS errors can lead to serious consequences. HMRC enforces penalties for late or incorrect submissions, and misclassified subcontractors can trigger audits. We help you avoid:
- Fines and interest charges
- Delays in payments or tax refunds
- Compliance breaches and reputational risk
Save Time Reclaim Focus
CIS admin can be repetitive and time-consuming. Outsourcing to our team means:
- Fewer errors and missed deadlines
- Less time spent on manual paperwork
- More time for project delivery and client relationships
Save Money. Avoid Mistakes
We help you:
- Ensure correct deduction rates and avoid overpayments
- Reclaim CIS tax where applicable
- Prevent costly compliance issues and penalties
Our proactive approach keeps your construction business financially sound and HMRC-ready.
Save Money. Avoid Mistakes
Thanks to smart software and streamlined systems, outsourcing is now more cost-effective than hiring in-house. Plus, when bookkeeping and account preparation are handled together, you avoid costly errors and duplication—especially during tax return season.
Save Time. Reclaim Focus
Small businesses lose up to 25% of their working hours managing financial paperwork. That’s time better spent serving clients, building your brand, and winning new business. Outsourcing your bookkeeping to us means
- Less admin stress
- More time for strategic growth
- Peace of mind knowing it’s done right
