A principle of taxation in which taxes are based on the income or resource-ownership ability of people to pay the tax. The income tax is one of the most common taxes that seeks to abide by the ability-to-pay principle. In theory, the income tax system is set up such that people with greater incomes pay more taxes. Proportional and progressive taxes follow this ability-to-pay principle, while regressive taxes, such as sales taxes and Social Security taxes, don\'t.
