We describe Hilbert series construction of finite-temperature EFT operator bases in the imaginary-time formalism on R^3 x S^1. The reduced spacetime symmetry distinguishes temporal and spatial structures, modifying the redundancy conditions compared to zero temperature. Applying spatial integration-by-parts and equations-of-motion constraints, this framework gives a complete non-redundant finite-temperature SMEFT operator basis up to dimension six.
