I'm starting a new job quite soon. My new employer has made it clear that, in addition to my salary, there'll be a contribution (calculated as 15% of gross salary) towards a pension plan but that the arrangements will be left to me. I'm currently saving a deposit for a new house and it would be useful if, for the next 12 months, I could take the 15% as an additional payment on top of my salary and defer setting up a pension fund until this time next year. Does anyone know if this is possible or even advisable? I presume there are BIK and tax implications. If the additional 15% is going to be taxed down to nothing then I might decide to simply set up the pension fund now and apply the contribution to it entirely.
