If you’re a UK contractor and you deal with subcontractors, chances are the Construction Industry Scheme (CIS) makes you want to chuck your laptop out the window. Between verifying subcontractors, filing CIS returns, and keeping HMRC off your back, it’s a job in itself. And let’s be honest, no one gets into construction to do paperwork. That’s where CIS accounting software comes in. Specifically, Xero, a tool that’s actually built to make all this stuff easier.
What is CIS (and Why Should You Care)
Quick refresher: under CIS, if you’re a contractor, you have to deduct tax from subcontractors’ pay before it even hits their account, then hand it over to HMRC. Lovely, right?
Your CIS responsibilities include:
Checking your subbies are legit (with HMRC)
Deducting CIS at the rate HMRC sets; normally 20%, 30% if they’re not registered, or 0% if they have gross payment status
Sending them a proper CIS deduction statement
Filing a CIS return to HMRC every month
Making sure HMRC actually gets the money
Miss a step? You could get fined, or worse, end up doing extra admin.
Why CIS Accounting Software is a No-Brainer
Doing CIS manually is like laying bricks with a teaspoon. It works… but why would you?
