The talk will first give an overview of the Large Hadron Collider (LHC) and the CMS experiment. The CMS detector records collisions from two high-energetic proton beams circulating in the LHC. An integral part of the CMS physics program are analyses with tau leptons in the final state. An overview will be presented on identification of hadronically decaying tau leptons in this dense hadronic environment at the LHC and its role in Higgs physics, ranging from H(125) boson measurements to searches for additional Higgs bosons.
