Firstly, an AMRF is a post retirement product. So you cannot add to it.
Yes you could establish a new PRSA and contribute up to 40% of salary into such. Even better if your new employer would contribute something (up to overall limit of 40%).
At present you cannot access the AMRF, but:
- when you get the State Pension ( assuming full State Pension) at age 67, the AMRF can possibly convert to an ARF (assuming your guaranteed pension income now exceeds €12,700 pa).
- there is a review under way st present around “pension rules” and changes are possible in the ARF/AMRF regime. But hard to predict what or when.
However even if you were able to access the AMRF funds, there would likely be a tax hit. So not such a good idea ( in my opinion) to give up your pension for a son’s deposit (unless of course you have very good pension provision).
