MSSM Higgs searches with tau lepton final states in CMS

The present understanding of large mass MSSM Higgs sector is reviewed. The most profitable channels: A/H $\to \tau \tau$ and $H^{\pm} \to \tau \nu$ are considered; a glimpse of the trigger chain studied for events with tau lepton final states is presented. The MSSM Higgs discovery reach of the general-purpouse experiment CMS is summarised.
