Using LEP1, SLD and LEP2 data, for tau lepton production, and data from colliders and LEP2, for W decays into tau leptons, we set model independent limits on non-standard electromagnetic and weak magnetic moments of the tau lepton. The most general effective Lagrangian giving rise to tau moments is used without further assumptions. Precise bounds (2σ) on the non-standard model contributions to tau electromagnetic (−0.007<aγ<0.005), tau Z-magnetic (−0.0024<aZ<0.0025) and tau W-magnetic (−0.003<κW<0.004) dipole moments are set from the analysis.
