We present an update on the calculation of flavor diagonal nucleon axial, scalar and tensor charges on eight 2+1+1-flavor MILC HISQ ensembles using Wilson-clover fermions. We discuss the excited state contributions (ESC) in the connected and disconnected diagrams, nonperturbative calculation of the renormalization constants and flavor mixing in the RI-sMOM scheme. These data are extrapolated to the physical point using a simultaneous chiral-continuum-finite-volume fit.
