As a contractor, your obligation is to deduct money from a sub-contractor’s payments and pass it to HM Revenue and Customs (HMRC).
Rules you must follow
Register as a Contractor
Contractors must register for the scheme prior to paying any subcontractors, you must also be registered for PAYE, these can be done at the same time.
If you are already registered for PAYE, you can call the CIS helpline, 0300 200 3210, to register you as a contractor quick and easily by giving your UTR and PAYE reference.
Employee or subcontractor?
This is a detailed area, more information can be found from HMRC or speak with Nicola to determine if you have any queries. https://www.gov.uk/employment-status/selfemployed-contractor
CIS Verification
You must ensure your subcontractors are registered for Construction Industry Scheme (CIS) with HMRC. Once verified HMRC will advise on the rate of deduction.
You will need your subcontractors
Deadline – verification must take pace prior to first payment to subcontractor
Making Deductions
The Construction Industry Scheme (CIS) deduction rates are:
You must pay these deductions to HMRC - they count as advance payments towards the subcontractor’s tax and National Insurance bill.
To make a CIS deduction from a subcontractor’s payment, start with the total (gross) amount of the subcontractor’s invoice.
Take away the amount the subcontractor has paid for:
Finally, deduct the CIS percentage rate (as given to you by HMRC) from the amount left. You’ll be left with the net amount you need to pay the subcontractor.
For instance £1,000 @ 20% deduction rate
£1,000 x 20% = £200 tax to be deducted and paid to HMRC and the Subcontractor receives £800.
File Monthly Returns
This can be done via commercial software or CIS online service; you must declare on your return that the subcontractors are not employees.
If a subcontractor has Gross Status, you must still submit on your return.
If you have made no payments, you are still required to submit a nil return.
Deadline: returns must be filed by 19th of every month following the last tax period, 6th to 5th.
For instance a return made on 19th of June will be for the period 6th May to 5th June.
The period dates are for actual payments made to subcontractors, not invoices received.
Record keeping
You must keep records for 3 years of:
If you made deductions, you must keep records of cost of materials invoice you for, excluding VAT.
You may be fined up to £3,000 if you cannot show your CIS records when asked by HMRC.
