HMRC has strict rules called the Construction Industry Scheme (CIS), which affect the way that contractors in the construction industry handle paying their subcontractors in the UK. Why does it matter if I’m a subcontractor or contractor? It’s crucial that you know whether you’re considered a contractor or a subcontractor under the rules, so that you pay the right amount of tax and National Insurance. Under the Construction Industry Scheme contractors make deductions from their subcontractors’ invoices, and pay these on to HMRC via a CIS return. It’s similar to the way in which employers make deductions for their employees’ tax and National Insurance. These deductions are basically an advance payment towards the subcontractor’s tax bill for the year. How much are CIS deductions? This depends on whether or not the subcontractor is registered for the Construction Industry Scheme. Contractors must verify their new subcontractor with HMRC before any work starts, so they can confirm their registration and tax status. This CIS registration status is important, because it affects how much the contractor must deduct from the subcontractor’s invoice before they pay it. If a subcontractor is registered for CIS, the contractor must deduct 20% of the invoice’s value before paying them When a subcontractor isn’t registered for CIS, the contractor must deduct 30%. Ouch!

As far as the Construction Industry Scheme (CIS) is concerned, a subcontractor is a business or organisation which agrees to carry out construction work on behalf of a contractor. Even if you hire employees or other subcontractors to help you complete the work, you can still be considered a subcontractor for CIS. You might accept the contract as a self-employed sole trader or through your own limited company, or as some other type of business structure such as a partnership. Subcontractors can also be: An agency or organisation which carries out construction work for a contractor using its own workers, or which supplies them to a contractor. This is different to an agency which ‘introduces’ someone with the intention that the contractor becomes their employer. A local authority or some other type of public organisation A gang leader (sometimes known as a ganger) who is contracted to coordinate and supervise a team Is being a subcontractor the same as being an employee? No, being a subcontractor isn’t the same as being directly employed by a contractor. Rather than working for the contractor as a regular employee, the contractor is basically your client. That said, it’s the contractor’s responsibility to assess your employment status when you agree to carry out any work for them as a subcontractor. They should use HMRC’s Confirmation of Employment Status Tool (CEST) to do this – it’s not up to them to choose! What makes a contract exempt from CIS? Not every contract will come under CIS rules. For instance if the work is being paid for by a trust or a charity. There are also some circumstances when HMRC will exempt a contract from CIS. For example If a contractor pays a subcontractor to carry out work worth less than £1,000 on property which belongs to them (not including the cost of materials). Exemptions aren’t given automatically though. Does CIS only apply in the UK? Yes, the Construction Industry Scheme only applies to work taking place in the UK. A UK firm can have a contract to carry out work overseas and CIS won’t apply. On the other hand, an overseas firm doing construction work in the UK might be subject to CIS, so always check! What do I need to do if I’m a subcontractor? If you do fit the criteria of a subcontractor working in the construction industry. Then ideally you should register for CIS as soon as possible. Registering means that contractors will make deductions at the lower rate, and this can make it easier to manage your cash flow throughout the year. You’ll also need to give information to the contractor you’re carrying out work for. So that they can verify your CIS registration status. The information you provide depends on how you operate your business: Sole trader: Your Unique Taxpayer Reference (UTR) number and National Insurance number Limited company: Company name, registration number, and company UTR number Partnership: The name of the nominated partner, and the partnership’s trading name and UTR number Do I need to submit a CIS return? It’s the contractor’s responsibility to submit a CIS return each month. So as a subcontractor you won’t need to worry about that bit. You will still need to submit tax returns for your business as usual though. The good news is that if you overpay tax through CIS during the year. You’ll be able to claim a tax rebate once you submit your return. Yet another reason to get it in as early as possible! Learn more about our online accounting services for businesses like yours.
