Brief description: A tax on a good will shift the supply curve vertically upwards by the amount of the tax. If the demand for the good is inelastic this will lead to a small fall in quantity and a large increase in price.

Detailed description: Where demand for the good being taxed is inelastic the majority of the tax will be borne by the consumer as the price will rise significantly. If demand was perfectly inelastic then the full amount of the tax would be borne by consumers.
