We calculate a one-loop level electric dipole moment (EDM) of the tau lepton that arises from scalar/pseudoscalar Higgs mixing in a type II two Higgs doublet model. Numerical results at m_0 = 125 GeV give an EDM of 3.66 × 10^(-24) e cm for tanβ = 1 and 2.33 × 10^(-21)e cm for tanβ = 30. The predicted EDM is still far below the current best experimental limit of |d_τ| < 3.9 × 10^(-17) e cm; however, it can be much larger than the tau EDM of the Standard Model.
