The radiative corrections to the $\tau^-\to (P_1P_2)^-\nu_\tau$ ($P_{1,2}=\pi, K$) decays are calculated for the first time. The structure-dependent contributions are obtained using Resonance Chiral Theory. Our results, whose uncertainty is dominated by the model-independent corrections, enable precise tests of CKM unitarity, lepton flavor universality, and non-standard interactions.
