We present an accurate numerical table for the relativistic corrections to the thermal Sunyaev-Zeldovich effect for clusters of galaxies. The numerical results for the relativistic corrections have been obtained by numerical integration of the collision term of the Boltzmann equation. The numerical table is provided for the ranges 0.002≤θ_e≤0.100 and 0≤X≤20, where θ_e=k_BT_e/m_ec², X=(h/2π)ω/k_BT₀, T_e is the electron temperature, ω is the angular frequency of the photon and T₀ is the temperature of the cosmic microwave background radiation. We also present an accurate analytic fitting formula that reproduces the numerical results with high precision.
