In this proceeding we review the status of theoretical predictions for top pair production and decay at differential level. Concerning stable tops we focus on the NNLO QCD+NLO EW combination, the NNLO+NNLL$'$ calculation and the merged $t \bar t+t \bar t j$ results at NLO QCD+EW accuracy. We further present results at the decay level including off-shell effects in the semi-leptonic decay mode of the top-quark pair at NLO in QCD.
