  Ta$_4$Pd$_3$Te$_{16}$ is a recently discovered superconductor that has been
suggested to be an unconventional superconductor near magnetism. We report
electronic structure calculations showing that in spite of the layered crystal
structure the material is an anisotropic three dimensional metal. The Fermi
surface contains prominent one and two dimensional features, including nested
1D sheets, a 2D cylindrical section and a 3D sheet. The electronic states that
make up the Fermi surface are mostly derived from Te $p$ states, with small Ta
$d$ and Pd $d$ contributions. This places the compound far from magnetic
instabilities. The results are discussed in terms of multiband
superconductivity.
