Why this sector
What makes finance work different here
A construction business may have many projects running at once, each with different suppliers, labour costs and payment stages. Small errors can quickly affect cash flow.
Subcontractor payments also follow specific tax rules. That's why many construction job adverts ask for CIS experience by name, as well as Sage skills.

Sector basics
Useful things to know
A short introduction, not legal or tax advice. Rules can change, so check the sources below.
01
CIS deductions
Contractors usually deduct 20% from payments to registered subcontractors and 30% from unregistered subcontractors. Those with gross payment status have no advance deduction.
02
Who the scheme covers
Contractors must register. Subcontractors don't have to, but those who don't face the higher deduction. Employees don't register.
03
VAT reverse charge
Since 1 March 2021, the domestic reverse charge has applied to many building and construction services between VAT-registered and CIS-registered businesses.
How we help
Get ready for these roles
You'll build the ledger, reconciliation, VAT, payroll and software skills these roles need. We can also introduce sector basics such as CIS, so you understand the terms employers use. Detailed job costing and contract rules are usually learned in the role.
Later on: With more experience, people can move into assistant accountant, quantity surveying support or commercial finance roles. Those roles usually need further experience or qualifications.
Develop practical skills in bookkeeping, VAT, financial transactions and record management, giving you the knowledge and confidence to support day-to-day accounting and finance operations.
Develop advanced payroll skills in processing, compliance, tax, National Insurance and payroll software to confidently manage accurate payroll operations.
CIS is the Construction Industry Scheme. Contractors deduct money from subcontractors' payments and pass it to HMRC as advance tax and National Insurance.
