We study the exclusive decay B-s --> tau(+)tau(-) in the general two Higgs doublet model. We analyse the dependencies of the branching ratio on the model parameters, including the leading order QCD corrections. We found that there is an enhancement in the branching ratio, especially for r(tb) = (xi) over bar (U)(N,tt)/(xi) over bar (D)(N,bb) > 1 case. Further, the neutral Higgs effects are detectable for large values of the parameter (xi) over bar (D)(N,tautau).
