We present a detailed study of the decays of the Higgs bosons H{sup +}, H{sup 0}, and A{sup 0} within the Minimal Supersymmetric Standard Model including SUSY-QCD corrections. We find that the supersymmetric modes t-tildeb d-bar t-tildet d-bar, and for large tan {beta}b-tildeb d-bar can dominate the H{sup +} (H{sup 0}, A{sup 0}) decays in a wide range of the model parameters due to the large Yukawa couplings and mixings of t-tilde and b-tilde. Compared to the conventional modes H{sup +}{yields}{tau}{sup +}{nu}{sub {tau}}, tb-bar, and H{sup 0}, A{sup 0}{yields}tt-bar,bb-bar, the supersymmetric modes can have an important impact on the Higgs boson searches at future colliders.
