The recent observation of the purely leptonic decay B±→τ ±ντ at the B factories permits a sizable contribution from a charged Higgs boson (H±). Such a H± would also contribute to the decays Ds±→μ±νμ and Ds±→τ± ντ, which are being measured with increasing precision at CLEO-c. We show that the branching ratios of Ds±→μ±νμ and Ds±→τ±ντ could be suppressed by up to 10% from the standard model prediction, which is larger than the anticipated precision in the measurements of these decays at forthcoming BES-III.
