A withholding tax, also called a retention tax, is a government requirement for the payer of an item of income to withhold or deduct tax from the payment, and pay that tax to the government.
 In most jurisdictions, withholding tax applies to employment income.
 Many jurisdictions also require withholding tax on payments of interest or dividends.
 In most jurisdictions, there are additional withholding tax obligations if the recipient of the income is resident in a different jurisdiction, and in those circumstances withholding tax sometimes applies to royalties, rent or even the sale of real estate.
 Governments use withholding tax as a means to combat tax evasion, and sometimes impose additional withholding tax requirements if the recipient has been delinquent in filing tax returns, or in industries where tax evasion is perceived to be common.
The Windfall Tax was a tax on what were claimed to be "the excess profits of the privatised utilities" and was introduced by the Labour government of Tony Blair in 1997.
 It followed from their manifesto commitment made during the 1997 general election campaign to impose a "windfall levy" on the privatised utilities.
 The tax came after 18 years of Conservative government, which had seen the privatization of many state-owned assets, at prices which many considered too low.
 It aimed to "put right the bad deal which customers and taxpayers got from the privatisation of the utilities".
 The tax produced an estimated one off income to the government of £5 billion, which was used to fund the New Deal, a welfare-to-work program that sought to tackle long-term unemployment, as well as providing capital investment for schools and the University for Industry (Learndirect).
An indirect tax (such as sales tax, per unit tax, value added tax (VAT), or goods and services tax (GST)) is a tax collected by an intermediary (such as a retail store) from the person who bears the ultimate economic burden of the tax (such as the consumer).
 The intermediary later files a tax return and forwards the tax proceeds to government with the return.
 In this sense, the term indirect tax is contrasted with a direct tax, which is collected directly by government from the persons (legal or natural) on whom it is imposed.
 Some commentators have argued that "a direct tax is one that cannot be changed by the taxpayer to someone else, whereas an indirect tax can be."
