There is a requirement for all employment intermediaries and agencies to report details about their contractors on a quarterly basis.
HMRC will require the following information:
National Insurance number (if no date of birth and gender provided)
Date of birth (if not providing National Insurance number)
Gender (if not providing National Insurance number)
Passport number or ID card number (if not a UK citizen)
Reason why income tax and National Insurance has not been deducted by the employment intermediary
Name and address of the business supplying the worker to the employment business
The number of hours to which the payment relates
Your agency will ask you to confirm all of this information and they are obliged to report it to HMRC and will be penalised if the report is late.
If you are the only fee earning contractor working through your company then you do not need to take any actions, your agency will be required to provide the information to HMRC.
If you have more than one fee earning contractor then the reporting requirements will apply.
