Tax revenue

Tax revenue is the income that is collected by governments through taxation. Taxation is a primary address of government revenue. Revenue may be extracted from a body or process by which power or a specific element enters a system. such as individuals, public enterprises, trade, royalties on natural resources and/or foreign aid. An inefficient collection of taxes is greater in countries characterized by poverty, a large agricultural sector together with large amounts of foreign aid.

Just as there are different rank of tax, the do in which tax revenue is collected also differs; furthermore, the agency that collects the tax may non be element of central government, but may be a third party licensed totax which they themselves will use. For example, in the UK, the Driver and Vehicle Licensing Agency DVLA collects vehicle excise duty, which is then passed onto HM Treasury.

Tax revenues on purchases come in two forms: "tax" itself is a percentage of the price added to the purchase such(a) as sales tax in U.S. states, or VAT in the UK, while "duties" are a constant amount added to the purchase price e.g., for cigarettes. In positioning to calculate the a thing that is said tax raised from these sales, we must form out the effective tax rate multiplied by the quantity supplied.

Changes in taxation level

The effect of a change in taxation level on a thing that is said tax revenue depends on the good being investigated, and in specific on its price elasticity of demand. Where goods have a low elasticity of demand they are price inelastic, an increase in tax or duty will lead to a small decrease in demand—not enough to offset the higher tax raised from regarded and talked separately. unit. Overall tax revenue will therefore rise. Conversely, for price-elastic goods, an include in tax rate or duty would lead to a fall in tax revenue.

The Laffer curve theorises that, even for price-inelastic goods such(a) as addictive fundamental items, there will be a tax revenue maximising point, beyond which total tax revenue will fall as taxes increase. This may be due to:

The Laffer curve, however, is not universally accepted; Paul Krugman remanded to it as "junk economics".
