The production of a Higgs boson in association with jets suffers from large higher order corrections, which are known at NNLO for a single accompanying jet and at NLO for up to three jets. These results are computed in an effective theory where the heavy quark loops, mediating the coupling between the Higgs boson and the gluons, are integrated out. As the LHC is delivering more and more precise data, it is important to understand in detail the validity range of such effective theory predictions. In this talk I will compare them to results obtained in the full theory, considering top and bottom quark mass effects, for up to three extra jets.
