The CIS & Handing Over Responsibilities

The construction industry in the UK which is worth over £362 billion. This means the sector is to achieve an annual average growth rate (AAGR) rise of 1% per year until 2027. In 2019, it was said to have contributed to 6% of all UK economic output. To put it lightly, the construction industry is a mega sector which UK trade and the economy heavily relies on.

Due to the amount of alleged tax evasion and fraudulent behaviour in the industry, the Construction Industry Scheme (CIS) was introduced. The CIS is a HMRC scheme where contractors deduct money from a subcontractor’s payments and pass it to HMRC. The deductions count as advance payments towards the subcontractor’s tax and National Insurance. Contractors must register for the scheme. Subcontractors do not have to register, but deductions are taken from their payments at a higher rate (30% as opposed to 20%) if they’re not registered.

Because of the amount of detail and time it takes to process CIS correctly, there are many benefits to outsourcing CIS responsibilities. We go through the positives of doing this, and why undergoing CIS responsibilities in-house can lead to many negative consequences…

What Are CIS Responsibilities?

There are overwhelming benefits to handing over CIS responsibilities to a professional firm such as an accountant like ourselves. For clarity, it’s important going over exactly what CIS covers. CIS is deemed to include most construction work such as:

  • a permanent or temporary building or structure
  • civil engineering work like roads and bridges
  • preparing the site – for example, laying foundations and providing access works
  • demolition and dismantling
  • building work
  • alterations, repairs and decorating
  • installing systems for heating, lighting, power, water and ventilation
  • cleaning the inside of buildings after construction work

When registering for the Construction Industry Scheme (CIS), you’re still responsible for paying the correct tax and National Insurance for your business, even if deductions have been made by contractors throughout the year. Contractors will give you a monthly statement of what they’ve paid you and deductions they’ve made to help with your accounting.

If you’re a sole trader or partner, you should submit your Self-Assessment return at the end of the tax year. HMRC will then calculate your tax and National Insurance amount, subtracting any deductions made by contractors. If you are set up as a Limited Company and have gross payment status, you will need to declare all your income in your Corporation Tax return as usual. If you pay CIS deductions, you must claim these back through your company’s monthly payroll scheme. Do not try to claim back through your Corporation Tax return as there’s a chance you could get a penalty from HMRC for incorrect filing.

It all sounds rather complicated, doesn’t it?

What Are The Benefits To Outsourcing CIS Responsibilities?

As you can see by all the work needing to be recorded and verified correctly, there’s a fair amount of admin and filing which goes with the CIS. Because of this, often construction businesses who do this in-house encounter many problems. Penalties for late monthly returns start off at the £100 mark. Likewise, an incorrect status for subcontractor on monthly return can result in a penalty of up to £3,000.
