Revenue job with IPASS cert

Hi all,
I''ve recently completed level 5 payroll manual&computerised through FETB and really enjoyed the course. I would like to move forward and considering getting an IPASS Cert in Payroll Techniques(level 6).

As much as a payroll admin in private sector looks like a great job, my goal is to get to the civil service like revenue as an EO. The question is- is there a chance they would consider an IPASS cert as an accounting related qualification? Or I should go a different path like tax technician or ATI? I also hold a level 8 degree in a different field and from another EU country, but don't think that would be enough and trying to increase my chances.

Would appreciate any insight.
