Construction & CIS - Frequently Asked Questions
The Construction Industry Scheme (CIS) is an HMRC scheme covering payments from contractors to subcontractors for construction work. If you pay subcontractors, you must register as a contractor with HMRC. We can handle registration and every monthly filing for you. Current rates and rules are published at gov.uk.
Yes. We deal with this regularly. We will bring your returns up to date, deal with HMRC on your behalf where needed, and put a system in place so it does not happen again.
Domestic Reverse Charge changes who accounts for VAT on most construction services between VAT-registered businesses — the customer accounts for the VAT rather than the supplier. If you are VAT-registered and work in construction, it almost certainly applies to you. We make sure your invoicing and VAT returns are set up correctly.
