Optimal capital taxes may be positive in the steady state in Ramsey models with an incomplete set of factor taxes. I show this possibility crucially depends on how fiscal policy is constrained at date t = 0. If the government is barred from manipulating the value of initial assets, the Chamley-Judd result reappears: the optimal capital tax is always zero in the steady state.
