In light of the Higgs discovery and the nonobservation of sparticles at theLHC, we revisit the SUSY induced top quark flavor changing decay into the Higgsboson. We perform a scan over the relevant SUSY parameter space by consideringthe constraints from the Higgs mass measurement, the LHC search for SUSY, thevacuum stability, the precision electro-weak observables as well as $B \to X_s\gamma$. We have the following observations: (1) In the MSSM, the branchingratio of $ t \to c h$ can only reach $3.0\times10^{-6}$, which is about oneorder smaller than previous results obtained before the advent of the LHC.Among the considered constraints, the Higgs mass and the LHC search forsparticles are found to play an important role in limiting the prediction. (2)In the singlet extension of the MSSM, since the squark sector is lessconstrained by the Higgs mass, the branching ratio of $t \to c h$ can reach theorder of $10^{-5}$ in the allowed parameter space. (3) The chiral-conservingmixings $\delta_{LL}$ and $\delta_{RR}$ may have remanent effects on $t \to ch$ in heavy SUSY limit. In the MSSM with squarks and gluino above 3 TeV andmeanwhile the CP-odd Higgs boson mass around 1 TeV, the branching ratio of$t\to c h$ can still reach the order of $10^{-8}$ under the constraints.
