	In this work, we use the results from Higgs searches in the γγ and ττ decay channels at LHC and indirect bounds as BR(B→Xsγ) to constrain the parameter space of a generic MSSM Higgs sector. In particular, we include the latest CMS results that look for additional Higgs states with masses up to 1 TeV. We show that the ττ channel is the best and most accurate weapon in the hunt for new Higgs states beyond the Standard Model. We obtain that present experimental results rule out additional neutral Higgs bosons in a generic MSSM below 300 GeV for any value of tanβ and, for instance, values of tanβ above 30 are only possible for Higgs masses above 600 GeV. ATLAS stored data has the potential to render this bound obsolete in the near future.
