If the parameter tanβ of the minimal supersymmetric model is large, then b and τ Yukawa interactions are important. These can significantly modify the masses and decays of sparticles. We describe new calculations which allow a reliable exploration of large tanβ values, and discuss implications for collider experiments. For large values of tanβ, charginos and neutralinos may dominantly decay to τ leptons or b quarks. The usual cross sections for multilepton signatures may be greatly reduced, but supersymmetry may be detectable via new signals involving τ's or b's in the final state.
