We assume that the new physics is a charged Higgs. We show that sizeable CP-violating effects are possible in tau -> a_1 pi nu_tau (polarization-dependent rate asymmetry) and tau -> omega pi nu_ tau (triple-product asymmetry). The Delta S=1 decay tau -> K pi pi nu_tau can proceed via several resonances. We construct two modified rate asymmetries and a triple product asymmetry for this decay and discuss the potential sensitivities of these asymmetries.3 pages, 1 figure, Flavor Physics & CP Violation Conference, Taipei, 2008; note added to correct an incorrect statement in the text; reference updatedHigh Energy Physics - Phenomenologytext
