In 2019, revenue from personal income taxes made up 24 percent of total tax revenue across OECD countries. Countries tax labor income in various ways through payroll taxes, personal income taxes, and, in some cases, surtaxes.
Between 2018 and 2021, eight European countries in the OECD changed their top personal income tax rates. Of these eight countries, four cut their top personal income tax rates while the other four raised their top rates.

A surtax in Greece has been temporarily suspended. The Netherlands made a slight change to its personal income tax rates. Turkey added a new top personal income tax bracket.
As of 2021, the Czech Republic has reintroduced progressive taxation with a top rate of 23 percent on income beyond CZK 1 million (US $78,000). Previously, a 15 percent flat tax applied.
Greece reduced the top personal income tax rate from 55 to 54 percent (44 percent income tax plus 10 percent solidarity surcharge) in 2020.

In 2018, Latvia shifted its system from a flat tax on personal income to a progressive tax. Prior to this change, Latvia applied a 23 percent flat tax.

Spain has a fiscally decentralized system with personal income tax rates that are a combination of national and regional policies. Madrid has the lowest combined personal income tax rate in the country—a 21 percent local tax rate plus the current 24.5 percent national income tax rate results in a 45.5 percent combined rate. The highest rate is 54 percent in Valencia Community. In 2020, the national rate was increased from 22.5 to 24.5, thus increasing rates throughout the country.
