Overview
How we help with Construction & CIS
Construction carries rules no other sector has: the Construction Industry Scheme, domestic reverse charge VAT, and retention accounting. Getting them wrong is expensive and easy.
We handle CIS end to end: registering you as contractor or subcontractor, verifying subcontractors with HMRC, calculating deductions at the right rate, producing payment and deduction statements, and filing monthly CIS300 returns before the deadline. For subcontractors, we make sure deductions suffered are properly reclaimed rather than lost.
Alongside that we deal with the domestic reverse charge for construction services, retentions, applications for payment and contract-level margin reporting: the parts of construction accounting that generic bookkeeping usually mishandles.

FAQs
Construction & CIS: common questions
When are CIS returns due?
Monthly, by the nineteenth of the month following the tax month being reported. Late returns attract automatic penalties that escalate quickly.
What is the domestic reverse charge?
For most construction services between CIS-registered businesses, the customer accounts for the VAT rather than the supplier charging it. It changes both invoicing and cash flow, and catches out businesses that keep charging VAT as before.
I'm a subcontractor, how do I get my CIS deductions back?
Deductions suffered are reclaimed against your Self Assessment bill if you're a sole trader, or against PAYE and Corporation Tax if you operate through a limited company. We track what's been deducted through the year so the reclaim is accurate and isn't left until the return is due.
Do I need to verify subcontractors every time I use them?
Only the first time, or if they haven't been paid within the scheme for two tax years. We handle the HMRC verification and keep a record of the deduction rate that applies to each subcontractor.
