We have studied the neutral Higgs boson (NHB) contributions to the pure penguin process B --> phiK(S) in MSSM with middle and large tanbeta (say, > 8). We show that the alpha(s) order hadronic matrix elements of NHB induced operators can make sizable effects on both the branch ratio and time-dependent CP asymmetry S-phiK. Under all the relevant experimental constraints, the Higgs mediated contributions to S-phiK alone can provide a significant deviation from SM and, in particular, lead to a negative S-phiK which is reported by BaBar and Belle.
