I know a number of AITI qualified solicitors who don't do any "pure" (ie non-legal) tax consultancy work.
A kink in the law in relation to professional/client privilege means that taxpayers who are at risk of criminal prosecution in relation to alleged tax evasion will need to consult a solicitor for confidential advice in relation to their defence, but this only applies in a tiny minority of cases and certainly not to the OP's situation.
Resorting to an AITI qualified solicitor for any relatively routine Revenue interaction would be serious (and imho expensive) overkill.
