CP violation in H^± decays into the three possible decay modes into ordinary particles, 1) H^± → tb, 2) H^± → ντand 3) H^± → W^± h0 is considered. Analytic expressions and numerical results for the CP violating decay rate asymmetries in the MSSM are obtained. Increasing tanβthe asymmetries for the fermionic decays, H^± → tb and H^± → ντ, decrease and it increases for H^± → W^± h0. The asymmetry of H^± → tb is most sensitive to the phase of At and can go up to 20%, the asymmetries of 2) and 3) depend mainly on the phases of Aτand M1. The asymmetry of 2) is smaller than 0.5% and of 3) can reach up to 2%.
