**Summary: **
In this paper, we calculate the Fourier coefficients of the
paramodular twist of a Siegel modular form of paramodular level
N by a nontrivial quadratic Dirichlet character mod p for p
a prime not dividing N. As an application, these formulas can be
used to verify the nonvanishing of the twist for particular
examples. We also deduce that the twists of Maass forms are
identically zero.
