Recent results from the D0 Experiment at the Fermilab Tevatron collider are presented on the search for the production of neutral Higgs bosons decaying into di-tau final states. In particular, searches with integrated luminosities of up to 2.2 fb^-1 of data are described in both the Higgs decaying into tau pairs as well as those produced in association with a b-quark. Since no significant excess is observed over the predicted backgrounds in either decay mode, limits on its production cross section times branching ratio are set for Higgs masses within the range from 90 to 300 GeV. The results are subsequently interpreted in the Minimal Supersymmetric Standard Model (MSSM) and regions in the (mA,
tan(beta)) parameter space for different MSSM benchmark scenarios are excluded at the 95% C.L. Future prospects for measurements with increased integrated luminosities delivered by the Tevatron are also discussed.
