All plans to suit your business
Check your subcontractor details
Quickly make sure a subcontractor is signed up to the CIS scheme. Add or import them as a Xero contact, then enter their UTR and expected deduction rate. Easy!

Automate CIS calculations
Xero works out the CIS deductions when you enter a subcontractor’s bill into the system. How? Xero uses accounting codes to apply the correct CIS deduction rate – whether that’s 20%, 30%, or 0% for subcontractors with ‘gross status’.

Generate your monthly CIS returns
A CIS return is a monthly report that contractors – not subcontractors – must send to HMRC. It lists how much you’ve paid subcontractors and the taxes you’ve deducted, and confirms they’re not your employees. Xero simplifies the process by keeping your info accurate and in one place.

How to file a CIS return online with Xero
As a contractor, you must send each CIS tax return by the 19th of the following month.
Double-check the info
CIS returns must include each subcontractor’s name, UTR, verification status, gross payments, and deductions.
Send returns from Xero
You can connect to HMRC from within your Xero software, send the return, and later check the status.
Follow HMRC rules
If you don’t pay any subcontractors for a month, you should send a nil return from Xero or tell HMRC by phone.

Deduction rates for CIS, explained simply
