CIS Compliance

Operating within the Construction Industry Scheme (CIS) brings specific and often complex tax compliance requirements for both contractors and subcontractors. At MAC Accounting, we work with many clients across the construction sector and understand the practical challenges of staying compliant while managing the day-to-day demands of running a business.

We ensure you are correctly registered with HMRC and help you establish the right systems from the start — including setting up your accounting software to accurately record sales, subcontractor payments, and deductions.

Contractors must verify subcontractors’ CIS status with HMRC, apply the correct deductions, submit monthly CIS returns, and issue payment and deduction statements — failure to do so can result in penalties, interest charges, and increased scrutiny from HMRC. Subcontractors, meanwhile, need to ensure deductions are correctly accounted for and reconciled against their own tax obligations.

We also provide clear guidance on reverse charge VAT rules, which add another layer of complexity for many construction businesses.

With MAC Accounting, you can be confident your CIS and VAT obligations are handled correctly and efficiently, helping you avoid common mistakes and maintain a good standing with HMRC.
