AUTOMATIC ENROLMENT IS A NEW LAW THAT REQUIRES ALL EMPLOYERS (INCLUDING ALL NANNY EMPLOYERS) TO MAKE SURE THEY HAVE A PENSION IN PLACE FOR THEIR EMPLOYEE.
Most nannies will need to be automatically enrolled into a pension scheme, and both the nanny and the employer will contribute to it.
In order to understand what to do and when to do it, HMRC have put together a Duties Checker: http://www.thepensionsregulator.gov.uk/en/employers/duties-checker.aspx
Nannies aged between 22 and the State Pension Age and earn above the Tax Free Allowance (currently £10,000) will be automatically enrolled. You can work out when your nanny will reach State Pension Age by using the Government’s State Pension Age Calculator: https://www.gov.uk/state-pension-age
A nanny who does not qualify to be automatically enrolled still has the right to ask to join a workplace pension.
