There is something else that you can all try and that is that registered nurses get an extra tax break for the payment of professional registration. £30+ I seem to remember when the registration doubled overnight.
That was two schemes, first was the tax exemption of payments as part of your profession, which can also be claimed for IET and IPEM membership. Second was the contribution to nurses registration fees which was then discontinued.
Of course there is one scheme that unless your a member of IPEM you can't claim back as its not recognised by the Inland revenue as a requirement, I wonder which one that is?
