The Construction Industry Scheme (CIS) identifies special rules for tax and National Insurance for taxpayers working in the construction industry.

The scheme is a minefield of regulations; meaning it is relatively easy to fall foul of the strict rules in place and even easier to incur penalties.

Does the Construction Industry Scheme apply to me?

Construction Industry SchemeThe scheme applies to all businesses who operate within the construction industry. That includes builders, tradesman, recruitment agencies who supply workmen, property developers and more. It is important that all contractors operate correctly as the penalties for non-compliance can be very expensive.

Businesses in this industry fall into one of two categories: Contractors or Subcontractors.

A contractor is a business or other concern that pays subcontractors for construction work, whereas subcontractors are those businesses that carry out the work for a contractor. These may be companies, partnerships or sole traders.

CIS construction investigations can be stressful and lengthy, especially for small businesses, putting extra strain on your business and personal life.

Under CIS rules and regulations, HMRC requires that contractors maintain full records of subcontractors’ details, payments to subcontractors and whether the subcontractors have been verified.

These records need to be kept for at least 3 years after the end of the tax year to which they relate. HMRC are entitled to inspect these records.

Record Inspection by HMRC

If a contractor receives a request from HMRC to inspect records it is important to seek professional advice before records are inspected under the Construction Industry Scheme.

In a CIS record inspection HMRC will not just be looking to see that the contractor has maintained proper records but they will also look at:-

  • The status of subcontractors to see whether they should be re-classified as employees
  • Whether the correct rate of tax has been deducted from payment. If not, HMRC may seek to recover any under-deduction of tax from the contractor
  • Whether the contractor is operating the CIS correctly. If not, HMRC can seek to hold the contractor liable for any under-deduction of tax.

It is very important to seek professional CIS advice in this situation.
