Lepton flavor violating Higgs boson decays (LFVHD) are studied in the context of the Minimal Supersymmetric Standard Model (MSSM) enlarged with three right handed neutrinos and their supersymmetric partners, and with the neutrino masses being generated by the seesaw mechanism. We compute the partial widths for these decays to one-loop order and analyze numerically the corresponding branching ratios in terms of the MSSM and seesaw parameters. We analyze in parallel the lepton flavor changing łj→ li γ decays and explore the maximum predicted rates for LFVHD, mainly for H0,A0 → τ μ decays, by requiring compatibility with neutrino and BR(łj→ li γ) data. We find LFVHD ratios of up to 10-5 in some regions of the MSSM-seesaw parameter space.
