We study the longitudinal polarization of the tau lepton in B{yields}D{tau}{nu} decay. After discussing possible sensitivities of {tau} decay modes to the {tau} polarization, we examine the effect of charged Higgs boson on the {tau} polarization in B{yields}D{tau}{nu}. We find a relation between the decay rate and the {tau} polarization, and clarify the role of the {tau} polarization measurement in the search for the charged Higgs boson.
