There exist about 3.7\ensuremathσ positive and 2.4\ensuremathσ negative deviations in the muon and electron anomalous magnetic moments (g\ensuremath-2). Also, some ratios for lepton universality in \ensuremathτ decays have almost 2\ensuremathσ deviations from the Standard Model. In this paper, we propose a lepton-specific inert two-Higgs-doublet model. After imposing all the relevant theoretical and experimental constraints, we show that these lepton anomalies can be explained simultaneously in many parameter spaces with mH>200 GeV and mA(m_H^\ifmmode±\else\textpm\fi)>500 GeV for appropriate Yukawa couplings between leptons and inert Higgs. The key point is that these Yukawa couplings for \ensuremathμ and \ensuremathτ/e have opposite sign.
