Once you are enrolled, you will receive a letter confirming that you are an active member of the Mastertrust. You will then have a period of one month from the date on the letter to either opt out online or complete and return an opt-out form. This is known as the opt out period.
As long as you have opted out by the end of the opt out period, you will be treated as having never been an active member of the Mastertrust and your contributions, if any, will be refunded via payroll, with appropriate deductions of PAYE and National Insurance.
If you do not opt out within the opt out period, then any contributions made to the Mastertrust will remain invested until you choose to take them at retirement or transfer them to another pension scheme.
