Current data for rare tau decays provide substantial upper limits on the LFV Yukawa couplings in the large $\tanβ$ region where $\tanβ$ is the ratio of vacuum expectation values of the two Higgs doublets. We show that measuring the LFV Higgs boson decays $h \to τ^\pm μ^\mp$ at future colliders can be useful to further constrain the LFV couplings especially in the relatively small $\tanβ$ region.3 pages, 1 figure.
