We examine the rare decays $B\to X_s\tau^+\tau^-$ and $B_s\to\tau^+\tau^- \gamma$ in the framework of technicolor with scalars. The contributions from both the neutral and charged scalars predicted in this model are evaluated. We find that the branching ratios could be enhanced over the standard model predictions by a couple of orders of magnitude in some part of parameter space. The forward-backward asymmetry and the distributions of differential branching ratios are also found to differ significantly from the standard model results. Such large new physics effects might be observable in the new generation of B experiments.
