We develop an exact nonperturbative framework to compute steady-state properties of quantum impurities subject to a finite bias. We show that the steady-state physics of these systems is captured by nonequilibrium scattering eigenstates which satisfy an appropriate Lippman-Schwinger equation. Introducing a generalization of the equilibrium Bethe Ansatz - the Scattering Bethe Ansatz - we explicitly construct the scattering eigenstates for the Interacting Resonance Level and Kondo Models and derive exact, nonperturbative results for their steady-state properties. In particular we compute nonequilibrium currents and entropy production.
