We present the general formalism for studying CP-violating phenomena in the production,mixing and decay of a coupled system of CP-violating neutral Higgs bosons at high-energy colliders. Considering the Minimal Supersymmetric Standard Model (MSSM) Higgs sector in which CP violation is radiatively induced by phases of the soft supersymmetry-breaking parameters, we apply our formalism to neutral Higgs production via bb, gg and W+ W- collisions and their subsequent decays into tau+ tau- pairs at the LHC. We discuss CP asymmetries in the longitudinal polarizations of tau+ tau- pairs based on a scenario in which all neutral Higgs bosons are nearly degenerate and the CP-violating signatures are resonantly enhanced.
