Understanding UK Tax Obligations for Construction Industry Scheme Businesses:


Navigating the tax landscape for your construction business or being a sub contractor can be challenging. Here’s a quick guide to some essential terms and concepts:

What Happens If You Work in the Construction Industry?


If you work in the construction industry then HMRC has created additional rules that you need to be aware of called the Construction Industry Scheme (CIS).  This scheme has been designed to try and reduce the frequency of construction workers who are either: not submitting tax returns, or failing to make self-assessment payments when they are due.

The scheme works by requiring the end client, referred to as the “Contractor”, to deduct tax at source (i.e. similar to an employer) equivalent to:

  • 20% of Invoiced (Labour) Value – Where the worker, referred to as the “Sub-Contractor” HAS registered with HMRC under the scheme.
  • 30% of Invoiced (Labour) Value – Where the worker, referred to as the “Sub-Contractor” HAS NOT registered with HMRC under the scheme.
  • Sub-contractors can also apply to HMRC directly to be paid GROSS under the scheme, so that all tax will be assessed at the year end, but certain criteria must be met to qualify.

Given the huge difference in tax rates it is clearly essential that workers who are “Sub-Contractors” register with HMRC in advance of starting work which is covered by the scheme, or as soon as possible afterwards, ideally before raising an invoice!

Additionally, if your business also employs other sub-contractors then you must also register under the scheme as a “Contractor” as well.

One of the most important areas you must consider before you can start out as a charity or social enterprise is the structure that will best suit your objectives both now and in the future, and how this structure will impact key areas such as:

  • Personal Liability – Where the risk of personal liability is a significant consideration for management then an incorporated legal structure is generally preferred.
  • Governance & Management Structure – Each of the different types of venture outlined below have different governance and management structures.
  • Funding – Where the primary source of funding will be grants from funding bodies then a charity structure is generally preferred. Likewise, where the primary source of funding will be from external investors then a share ownership structure is generally preferred.  In other circumstances a structure limited by guarantee is often preferred.

But ultimately all of these areas should be considered together before making any final decisions.  And the most essential aspect is to consider this at the outset, as changing structure in the future can often be complex and expensive.

Scope of the Scheme


The Construction Industry Scheme (CIS) covers most construction work, including: site preparation, building, decorating, and refurbishment.

For larger organisations such as: housing associations, government bodies, etc, there are also “deemed contractor” rules to include organisations which, are not specifically in the construction industry but, have spent more than £3 million on construction in the last 12 months.

However, there are a number of specific exclusions from the scheme, including:

  • Work paid for by a charity or trust
  • Work paid for by a governing body or head teacher of a maintained school on behalf of the local education authority
  • Work on the subcontractor’s own property and worth less than £1,000 excluding materials
  • Architecture and surveying
  • Scaffolding hire (with no labour)
  • Carpet fitting
  • Delivering materials
  • Work on construction sites that is clearly not construction (e.g. running a canteen)

Responsibilities of a CIS Contractor


As a “contractor” you have a number of initial and ongoing responsibilities, including:

  • Registering for the scheme online before you take on any subcontractors. Once you have registered HMRC will supply you with the following key employer information:
    • Unique Taxpayer Reference (UTR)
    • HMRC Payment Office Reference
    • HMRC Employer Reference
  • Making an accurate determination as to whether each worker is an employee or a sub-contractor. This is important because HMRC may later fine you if they decide you have made the wrong determination.
  • Verifying each sub-contractor online before making any payments to them, to determine whether they are registered under the scheme, and determine what rate of deductions to apply. In order to do this the sub-contractor will need to supply their own:
    • Unique Taxpayer Reference (UTR)
    • National Insurance Number
    • Where applicable their company or partnership name, registration number, and UTR.

  • Making CIS deductions at the appropriate rate (as advised by HMRC) before making payments to sub-contractors. The deductions should only be charged on the “labour” element of invoices.  And sub-contractors must be provided with a payment and deduction statement, and direct payment of the net amount, within 14 days of the end of the month.
  • Filing monthly CIS returns with HMRC, or notifying them that no return is due, within 19 days of the end of the month. Penalties for late filing can be quite severe.
  • Paying these CIS deductions to HMRC within 22 days of the end of the month.
  • Keeping accurate CIS records for all sub-contractors for at least 3 years.
  • Letting HMRC know about any changes to your business, including:
    • Change of address (personal or business)
    • Change your business structure
    • Death
    • If you stop trading or using subcontractors

As a specialist CIS Accountant, QAccounting offer CIS Contractor Services which fully comply with HMRC’s monthly and annual filing requirements!

Sub-Contractor CIS Reclaims


It is essential to understand that if you are a sub-contractor that, because HMRC have collected taxes “at source” before you have deducted expenses, in most cases you will have paid too much tax!  To correct this, you have the option to make a “CIS Reclaim” when you submit your next tax return, by recording the correct profit values for the year and the taxes already paid to HMRC at source.  HMRC will then repay this overpaid tax to the sub-contractors once they have processed the claim, which can take many months.

Unlike most other accountants who charge clients a percentage of the tax reclaimed for providing a CIS Reclaim service, QAccouting only charge a small flat rate fee making us market leaders in this space!
