We discuss the role that Higgs coupling measurements can play in differentiating supersymmetric extensions of the Standard Model. Fitting current LHC data to the Higgs couplings, we find that the likelihood fit is consistent with Standard Model values, but has a shallow gradient in the direction of suppressed (enhanced) bottom (top) quark couplings. In the minimal supersymmetric Standard Model, we demonstrate that for tan beta > 1, there is tension in achieving such fermion couplings, due to the structure of the Higgs quartic couplings. In anticipation of interpreting supersymmetric models with future data, we determine the required conditions to access this region of coupling space, which current data allow and may favor with increased statistics.
