We present a comprehensive error band on neutron matter properties at finite temperature (finite-T) including uncertainties on the nuclear interaction, the many-body method convergence, and the thermodynamical consistency of the approach. This study provides $\textit{ab initio}$ predictions for finite-T neutron matter employing chiral interactions which are selected on the basis of their performance in both finite nuclei and infinite matter at zero temperature. Since proper theoretical uncertainties at finite-T are still generally lacking, the band provided here represents a significant step forward in setting first-principles constraints on thermal aspects of the nuclear matter equation of state.
