A search for additional neutral Higgs bosons in the $\tau\tau$ final state is presented. The search is performed in the context of the minimal supersymmetric extension of the standard model (MSSM), using data from proton-proton collision collected with the CMS detector in 2016 at a center-of-mass energy of 13 TeV. The collected data corresponds to an integrated luminosity of 35.9fb$^{-1}$. No significant deviation above the expected background is observed. Model-independent limits at 95% confidence level are set on the product of the branching fraction for the decay into $\tau$ leptons and the cross section of the production mode.
