In this article we consider the possibility of observing nonstandard Higgsbosons in the H -> Z A -> Z tau+ tau- channel. We present three benchmarkscenarios in the NMSSM where H -> ZA is the dominant decay mode for one of thenonstandard Higgs bosons while the lightest CP-even Higgs is Standard Modellike. Using the latest CMS multilepton analysis based on 7 TeV LHC data, we putlimits on the signal cross-section, which constrain leptophilic scenarios.Projecting to future LHC analyses with improvements in background modeling, weshow that with O(30) fb^{-1} of data, such a multilepton analysis is very closeto constraining our NMSSM benchmarks. As we illustrate with a toy model, forlight A masses, the large boost of the A makes it inefficient to select twohadronic taus, since isolation and the transverse momenta are in tension. Thisefficiency could be improved by including boosted di-tau jets as an object infuture multilepton analyses. We also discuss different methods to confirm thisscenario by reconstruction of the m_H and m_A masses. In particular we considerthe transverse mass distribution, collinear mass distribution and an analyticalsolution using trial masses.
