PRSA and AVCs
I'm afraid its not as simple as you might think ...using PRSA as an AVC vehicle is a messy way to do it ..some, including me, feel its not techncially possible even though many are promoting this idea.
You scheme must offer an AVC facility ..I woudl find out about that first, before getting in to trying to pay AVCs to a PRSA. One of the disadvantages of paying AVCs to a PRSA is that you will probably have to pay them gross and claim back the tax relief afterwards. If you pay AVCs to your employer's scheme, you'll get tax relief at source from your employer.
