I had the reverse understanding, that employer contributions count in the calculation of the maximum contribution. I cannot find any clear confirmation on revenue or citizen information web sites however at the minute, it's very obscure for the normal layman. The official documentation keeps referring to "my" contribution, which I conservatively assumed includes what the employer is giving as well to me on my pension pot, albeit indirectly.
ie: if I pay 5%, and my employer pays 6%, and I am between 30-39 yo (max contribution is 20%), I can only add 9% in AVC (to reach 20%), not 15%.
Could we have some additional confirmation here from Brendan?
