CIS Contractor service | Online Account Filing

As a CIS Contractor,
what are my compliance obligations?

  • First of all you need to register online with HMRC as a CIS Contractor.
  • Deduct the appropriate CIS from your sub-contractor payments.
  • Submit your CIS Monthly returns on time.
  • Pay the money you deducted from your sub-contractors to HMRC on a Monthly basis.

This has nothing to do with your tax liability, you’re just deducting money on HMRC’s behalf, to fulfil the legal duty.

Contractor Accountant - CIS

When and how much should
I deduct from my
sub-contractors?

CIS should be deducted at the time of the payment itself. There are 2 different rates of deducting the CIS, one is regular 20% (for registered sub-contractors) and the other is set at a higher rate, being 30% (for non-registered sub-contractors).

For example, if you are to pay £2,000 to David, you should deduct and withhold £400 (if he is registered) or £600 (if he is not registered); then pay him the remainder.

CIS Sub-contractor Register

How do I know whether the
sub-contractor is registered or not?

HMRC has provided an online service to check whether the person (or the Company) you are working with is registered or not.

You must ask for their name, HMRC UTR, trading name (if any); and their address. All this information is required to enable you to verify them online.

CIS returns and Pay HMRC

How frequently do I need to
file CIS returns and pay HMRC?

You need to file Monthly CIS300 returns to HMRC, telling them how much you deducted and from whom. The return period always runs from the 6 th of each Month to the 5 th of next Month, and for submitting to HMRC, you are given until the 19 th of the Month in which the period ends. You must pay the (withheld) CIS to HMRC by the 22 nd (19 th in case you pay by post).

For example, for the Month of July, the CIS300 period is from the 6 th July to the 5 th August. The return should then be filed by the 19 th August, with the online payment following three days later on (or by) the 22 nd August.
