Abstract
We report on preliminary results from the calculations of the QCD equation of state
for 2+1+1 flavors using HISQ action. The calculations are performed on lattices with temporal
extents $N_{\tau}=6,~8,~10$, and $12$ and aspect ratio $N_{\sigma}/N_{\tau}=4$. We find that there is a significant
contribution to the pressure from charm quarks at temperatures $T> 300$ MeV.
