Adding personal taxes to the model lowers, but does not eliminate, the benefit from corporate debt. In the United States, taxes on capital gains are lower than on ordinary income and can be deferred. The effective rate on stock income is normally less than that on bond income, and although the personal tax on debt will lower the gain from corporate debt, it is not usually enough to eliminate it$.$ Therefore, there is still a gain from leverage using Miller$$s model, as well as the MM model with corporate tax.
