The amount of a tax shifted forward depends on the price elasticity of demand for the taxed good.A forward-shifted tax is a tax imposed on producers but passed on to consumers. The amount of a tax shifted forward depends on the price elasticity of demand for the taxed good. A backward-shifted tax is a tax borne by firms and input suppliers.
