We present a set of preliminary and final results on tau branching fractions and invariant mass spectra, and a search for the second class current decay tau -> pi eta'(958) nu_tau. The results include new studies of a large number 3 and 5-prong tau decay modes either inclusive or classified according the hadronic resonance content (K0S, eta, omega, etc.). All results are based on the analysis of the complete BaBar data set consisting on 430 million tau lepton pairs, corresponding to an integrated luminosity of 468 fb^-1, collected with the BABAR detector at the PEP-II asymmetric energy e+ e− storage rings.
