Low energy observables involving the Standard Model fermions which arechirality-violating, such as anomalous electromagnetic moments, necessarilyinvolve an insertion of the Higgs in order to maintain $SU(2) \times U(1)$gauge invariance. As the result, the properties of the Higgs boson measured atthe LHC impact our understanding of the associated low-energy quantities. Weillustrate this feature with a discussion of the electromagnetic moments of the$\tau$-lepton, as probed by the rare decay $H \rightarrow \tau^+ \tau^-\gamma$. We assess the feasibility of measuring this decay at the LHC, and showthat the current bounds from lower energy measurements imply that $13~\rm{TeV}$running is very likely to improve our understanding of new physics contributingto the anomalous magnetic moment of the tau.
