The presented analyses were performed by the Higgs to Complex States Working Group of the ATLAS Collaboration, using pp collisions data taken by the ATLAS detector in 2010 and 2011 at the LHC. An outline of the analysis and the result of the charged Higgs in the c¯s final state, which uses kinematic fitting algorithms, was presented. Upper limits on B(t → bH+) × B(H+ → c¯s) = 0.25 to 0.14 for mH± = 90 to 130 GeV have been derived. In the second part the charged Higgs in the hadronic τ final state analysis, which utilizes different techniques to estimate all background contributions from the data, was summarized. Values of the product of branching ratios B(t → bH+)×B(H+ → τ + ν), larger than 0.03 to 0.10 have been excluded in the H ± mass range 90 to 160 GeV.
