Two broad categories of taxes: a direct tax is levied on income or wealth and is borne by the same person who pays it, while an indirect tax is levied on goods and services and can be passed on to the final consumer.
The impact-versus-incidence test, the progressive-versus-regressive nature, and standard examples of each are core taxation facts, often in matching form.
Direct tax (burden not shifted, on income or wealth) versus indirect tax (burden shifted, on goods or services); GST and customs are indirect, income and corporation tax are direct.
Direct tax: on income or wealth, burden not shifted (income tax); indirect tax: on goods or services, burden shifted (GST).
