The CIS is a set of special rules for tax and National Insurance (NI) for those working in the construction industry. Businesses in the construction industry are known as 'contractors' and 'subcontractors'.
The scheme applies mainly to contractors and sub-contractors involved in construction however, certain businesses that are not in the business of construction but have a significant amount of annual spend may also count as contractors.
The rules for CIS changed substantially in 2007 resulting in the abolition of CIS certificates and registration cards.
Who does CIS apply to?
Types of work and business structures covered by CIS
The CIS can apply to all types of businesses that work in the construction industry in the UK.
• self-employed individuals working as sole traders
• limited liability partnerships (LLPs)
As well as traditional construction businesses like builders, the scheme can also apply to businesses like:
• labour agencies and staff bureaux
• gangmasters - or gang leaders
• property developers
Definition of construction work
CIS covers construction operations carried out in the UK. The rules of the scheme define the types of work that are classed construction operations. But as a general rule, the scheme includes almost any work that's done to a:
• permanent building
• temporary structure
• civil engineering work or installation
• Some examples of the types of construction work that are covered by the scheme include jobs like:
• site preparation
• general construction - bricklaying, roofing, plastering and so on
• alterations and extensions
• repairs and refurbishment
• dismantling work
The scheme defines 'construction' as a term with a broad meaning that includes:
• building things
• making things
• putting things together
• assembling things
HMRC for example define assembling prefabricated units and site facilities off-site as construction work.
Who is a contractor?
A contractor is a business, or other concern, that pays subcontractors for construction work including:
Businesses that carry out construction operations.
• Any property developers or speculative builders, erecting and altering buildings to make a profit.
• Gang leaders organising labour for construction work.
Deemed contractors are those concerns that carry out construction work on their own premises or investment properties and whose average annual expenditure in the period of 3 years, ending with their last accounting period, exceeds £1 million.
Ordinary householders having work done on their own properties or building a new house are not considered contractors
Who is a subcontractor?
A subcontractor is a business that carries out construction work for a contractor. It can include an agency if a worker carries out construction operations under the terms of the contract they have with the agency. This is not the case if the agency merely introduces the worker to the contractor.
Subcontractors also need to register with HMRC and should keep HMRC informed of any changes in their business (including changes to the structure, address, business name, partners etc).
The new CIS introduced statutory monthly reporting. Contractors have to make a monthly return to HMRC:
• confirming that the employment status of subcontractors has been considered
• confirming that the verification process has been correctly dealt with
• detailing payments made to all subcontractors and
• detailing any deductions of tax made from those payments.
The monthly return can be sent either manually or electronically and relates to each tax month (i.e. running from the 6th of one month to the 5th of the next). The deadline for submission is 14 days after the end of the tax month. Even if no subcontractors have been paid during a month, contractors still have to make a nil return. All contractors are obliged to file monthly even if they are entitled to pay their PAYE quarterly.
The penalties for late submission of CIS contractor monthly returns changed from October 2011 with the introduction of new legislation.
The current penalty regime is as follows:
Initial failure to meet due date
If a return is not received by HMRC by its due date of the 19th of the month, a penalty of £100 will be charged.
Return still outstanding two months after due date
If the return has still not been received by HMRC two months after its due date, a further penalty of £200 will be charged.
Return still outstanding six months after due date
If the return is still outstanding six months after its due date, a 'tax-geared' penalty becomes due. This penalty is the greater of 5% of any deductions shown on the outstanding return or £300.
Return still outstanding twelve months after due date
If the return is still outstanding twelve months after its due date, a second 'tax geared' penalty will becomes due based on the reason why HMRC determines the return is late.
