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.

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).
Monthly Returns
The new CIS introduced statutory monthly reporting. Contractors have to make a monthly return to HMRC:
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.
Penalties
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:
