I still don't understand why the employer needs to know - they grant tax relief on occupational contributions made through payroll. The employee makes his/her own AVC contributions through a PRSA and claim tax/PRSI relief manually. Revenue will do the aggregation and grant tax/PRSI relief up to the relevant age related limits. The employer only needs to know about this if the AVC contributions are also being made via payroll with tax/PRSI relief granted at source. Otherwise I don't see that they need to know and some employees might prefer to keep such matters private from them for one reason or another. Am I wrong?
