CIS, tied to
real work.
Not a spreadsheet.

CIS only works when subcontractor status, verification and payments match reality. Unibuild links the people you cleared on site to the CIS bands in your financial records, so deductions and year-end reconciliations cause fewer headaches and the HMRC letter does not surprise you.

§ 01What good CIS looks like

Six habits that keep
contractors out of trouble
and cash flowing fairly.

The HMRC letter does not arrive because somebody disliked your tax position. It arrives because the evidence chain broke. Below is the chain, and how the platform keeps it joined up.

01

Verify before pay

UTR verified live against HMRC on first engagement. Band fetched, stored on the subbie record. Match the people you cleared on site to the people you paid.

02

Auto-band per worker

0% (gross status), 20% (standard), 30% (unverified). Refreshed monthly from HMRC. Applied automatically to every AfP and certificate.
