Combined with experimental data on $B_s$ mass difference $\\Delta m_s$, the $h \\to \\mu \\tau$, and the $h \\to \\tau^+\\tau^-$ decay branching ratios from the LHC, we find that the Higgs FCNC couplings are severely constrained. The allowed regions for $B_s \\to \\mu \\tau$, $\\tau\\tau$ and $h \\to sb$ decays are obtained. Current data allow large CP violation in the $h \\to \\tau^+ \\tau^-$ decay.
