We calculate the (Formula presented) SUSY-QCD corrections to the widths of top and bottom squark decays into Higgs bosons within the minimal supersymmetric standard model. We give the complete analytical formulas, paying particular attention to the on-shell renormalization of the soft SUSY-breaking parameters. We also perform a detailed numerical analysis of both top and bottom squark decays into all Higgs bosons (Formula presented) (Formula presented) (Formula presented) and (Formula presented) We find that the SUSY-QCD corrections are significant, mostly negative, and of the order of a few ten percent.
