What it means

A tax is progressive when the average share paid rises as the income being compared rises. For example, Income Tax can be progressive when tax-free income and higher rates mean higher earners pay a larger percentage of their total income. Paying more pounds in tax does not by itself make a tax progressive: the percentage of income must also rise. A tax can work differently for different groups, so check which tax and incomes a claim refers to.

Example

In a made-up tax system, someone earning £20,000 pays £1,000 tax (5% of income), while someone earning £40,000 pays £6,000 (15%). This example is progressive because the higher earner pays a larger share, not just a larger amount.

Why it matters

It helps make discussions about who carries the cost of a tax more precise.
