For millions of Britons, retirement is supposed to bring financial certainty. After decades of working and saving, many expect their money to provide a stable income without unexpected demands from the taxman. But a growing number of pensioners are now finding themselves paying Income Tax.

The number of pensioners paying Income Tax increased from 6.7 million in 2021/22 to 8.8 million in 2025/26, according to analysis of HM Revenue and Customs figures by former pensions minister Steve Webb. That represents an increase of about 2.1 million people in four years.
