CIS Services UK for Contractors and Subcontractors. Ensure compliance with ACG.

Expert Construction Industry Scheme (CIS) services helping UK contractors and subcontractors stay compliant, avoid penalties, and maximise tax refunds.

If you work in construction in the UK, you already know that the Construction Industry Scheme (CIS) can be complicated. Whether you’re a contractor, subcontractor—or both—staying compliant with HMRC’s CIS services regulations is crucial. That’s where Audit Consulting Group steps in.

We provide expert, end-to-end CIS services designed to simplify compliance, avoid penalties, and ensure you get every penny you’re entitled to. From registrations to returns, verifications to deductions—we’ve got you covered.

CIS Accountant Services UK

Our CIS accountants provide full support for contractors and subcontractors across the UK. We manage CIS registration, subcontractor verification, monthly CIS returns, and tax reclaims to ensure full HMRC compliance.

Whether you need help with deductions, gross payment status, or CIS refunds, our team handles everything.

What Are CIS Services?

The Construction Industry Scheme (CIS) is a set of rules from HMRC that governs how payments are made between contractors and subcontractors in the construction industry. Under CIS, contractors must deduct money from payments to subcontractors and pass it to HMRC.

Our CIS services ensure:

• Proper registration and setup with HMRC
• Accurate monthly CIS returns
• Subcontractor verification
• Deduction statement generation
• Reclaim of overpaid CIS tax (especially for subcontractors)
• Advice on whether CIS applies to your work
• Peace of mind for both contractors and subcontractors

HMRC CIS Penalties

HMRC applies penalties for late CIS returns:

• £100 for 1 day late
• £200 after 2 months
• £300 or 5% of CIS deductions after 6 months
• Additional £300 or 5% after 12 months

We help contractors avoid these penalties by handling monthly CIS compliance.

Who Needs CIS Services?

You need CIS services if you are:

• A contractor who pays subcontractors for construction work
• A subcontractor providing labour or services to a contractor
• A business that does both (common in building and maintenance firms)

Whether you are an individual sole trader or a company managing large projects, CIS compliance is mandatory. We help you get it right, every month.

Gross Payment Status CIS

Subcontractors may apply for gross payment status to receive payments without CIS deductions. This improves cashflow and reduces tax reclaim delays.

We assess eligibility, prepare the application, and liaise with HMRC to secure gross payment approval.

Our CIS accountants manage both roles seamlessly.
