  Tau leptons play an important role in the physics program at the LHC. They
are used in searches for new phenomena like the Higgs boson or Supersymmetry
and in electroweak measurements. Identifying hadronically decaying tau leptons
with good performance is an essential part of these analyses. We present the
current status of the tau reconstruction and identification at the LHC with the
ATLAS detector. The tau identification efficiencies and their systematic
uncertainties are measured using W to tau nu and Z to tau tau events, and
compared with the predictions from Monte Carlo simulations.
