What is the
Industry Scheme?

The Construction Industry Scheme (CIS) collects tax at source for construction work. As a self-employed individual, you pay your taxes annually via a self-assessment. When working under CIS your payments from us may have deductions, which are credited to HMRC for your future tax liabilities. The deduction amount depends on your CIS tax verification level during the work – typically this tends to be a deduction rate of 20% or 30%, but can be 0% if you have gross payment status.  

With Giant sitting in the contract chain, correct tax deductions offer reassurance, avoiding unexpected tax bills during self-assessment.
