We present a calculation of soft-gluon corrections in FCNC top-quark production via anomalous t-q-g couplings. The soft anomalous dimension matrix is explicitly calculated at one-loop accuracy. This calculation allows threshold resummation at next-to-leadinglogarithm accuracy. We also derive expressions for the soft-gluon corrections at NLO and at NNLO.
