What is CIS?
The Construction Industry Scheme is a method of deducting tax from subcontractors in the building sector. Contractors deduct a percentage of the money owed on their payments to subcontractors and pass it over directly to HMRC. The amounts are effectively taxed at source as the sub-contractor does not get the money. The deducted CIS tax counts as advance payments towards the tax and National Insurance contributions that will be calculated upon completion of the subcontractor’s self-assessment tax return.
What do I need to complete a return?
Monthly CIS returns need to be submitted by the contractor to HMRC to disclose the amount of CIS which has been deducted and is therefore due to be paid over to HMRC.
The contractor needs from the subcontractor an invoice which states the money they are owed.
The invoice should split out the materials and labour with CIS only being deductible on the labour element of the invoice. CIS is deducted at 20% providing the subcontractor has a UTR (unique tax reference) number which should be displayed on the invoice. If there is no UTR number then CIS will be deducted at 30%.
How do I do it?
CIS periods run from the 6th of the month to the 5th of the month following – for example, 6th March – 5th April. The CIS return then needs to be submitted and the liability paid over within two weeks of the period end – 19th April for example in order to avoid facing late filing charges. The return can be manually entered under the contractor’s logon on the HMRC website or it can be submitted via numerous accounting software programmes. The CIS is payable to HMRC upon payment of the invoice and not the date the invoice is issued, so it should only be included on the CIS return at this point. Once the return has been submitted to HMRC, statements should be sent out to all subcontractors for their own records.
