In the inverse seesaw model (ISS), the smallness of the neutrino masses isrelated to the smallness of a lepton number violating mass term whilst theseesaw scale is naturally close to the TeV scale, which allows for largeeffects in lepton flavor and universality violating observables. With theongoing and planned measurements of the Higgs boson properties at the LHC, wefound timely to investigate the possibility of having large lepton flavorviolating Higgs decay (LFVHD) rates within the context of the ISS, consideringthe most generic case where three additional pairs of massive right-handedsinglet neutrinos are added to the Standard Model particle content. We presenta full one-loop computation of the LFVHD rates and analyze in full detail thepredictions as functions of the various relevant ISS parameters, which arerequired to be compatible with the present neutrino data and the presentexperimental bounds for the three LFV radiative decays, and also consistentwith other constraints, like perturbativity of the neutrino Yukawa couplings.At the end, we conclude on the maximum allowed LFVHD rates within the ISS,which may reach maximal values of order $10^{-5}$ for the $H \to e \bar \tau$and $H \to \mu \bar \tau$ channels, close to the expected future LHCsensitivities.
