Construction accountants handle Construction Industry Scheme deductions, monthly CIS returns, the VAT domestic reverse charge and job costing for builders and trades limited companies. Most fit the Complete or Growth package.

What is different for you.

The parts of the rules that matter most for this kind of company.

CIS on both sides

Subcontractors have tax deducted; contractors must deduct, report and issue statements.

02

Reverse charge VAT

Most construction services between VAT-registered businesses are reverse-charged.

03

Retentions and stage payments

Income earned but not yet received must be recognised correctly.

How the work differs for construction and CIS.

The parts of the job that matter most for this kind of company, and how we handle them.

01

The Construction Industry Scheme

Under CIS, contractors deduct tax from payments to subcontractors and pay it to HMRC. The deduction is 20% for registered subcontractors and 30% for unregistered ones. Subcontractors can apply for gross payment status if they meet the turnover and compliance tests.

We handle registration, verification of subcontractors and the monthly returns so your deductions are always right.

  • Registration and verification
  • 20% and 30% deduction rates
  • Gross payment status applications
02

Monthly returns and refunds

Contractors file a CIS return every month, due by the 19th, and pay what is owed. A limited company that has had deductions taken can offset them against its own PAYE and National Insurance liability, or claim a refund of any excess.

We file the returns, manage the offset and make sure any refund reaches the company.

  • Return filed by the 19th
  • Deductions offset against PAYE
  • Refunds claimed
03

VAT reverse charge for construction

For most building services provided between VAT-registered businesses, a domestic reverse charge means the customer, not the supplier, accounts for the VAT. It changes your invoices and your VAT returns, and getting it wrong means reclaiming or owing VAT you did not expect.

We apply the right treatment to each job and set your invoices up correctly.

  • Reverse charge applied per job
  • Invoice wording checked
  • VAT returns reconciled

The usual way, and ours.
