The size of the branching ratios for the {tau}{yields}{mu}{gamma} and {tau}{yields}{mu}{gamma}{gamma} decays induced by a lepton flavor violating Higgs interaction H{tau}{mu} is studied in the framework of effective field theories. The best constraint on the H{tau}{mu} vertex, derived from the know measurement on the muon anomalous magnetic moment, is used to impose the upper bounds Br({tau}{yields}{mu}{gamma})<7.5x10{sup -10} and Br({tau}{yields}{mu}{gamma}{gamma})<2.3x10{sup -12}, which are more stringent than current experimental limits on this class of transitions.
