British Prime Minister Rishi Sunak paid 508,000 pounds in tax during the last financial year, a report by his accountants revealed on Friday.

This substantial tax payment stems from income generated from Sunak's investments, which far exceeded his official salary.

Sunak holds the distinction of being the wealthiest prime minister in British history, thanks to his prior career in financial services and the significant family fortune of his wife, whose father established the Indian IT services company Infosys.

This disclosure marks the second occasion on which Sunak has released details of his tax affairs since assuming office in 2022. According to the report, Sunak earned 139,000 pounds from his roles as a member of parliament, finance minister, and prime minister between April 2022 and March 2023. Additionally, his investments yielded a substantial 2.1 million pounds in income.

Of this investment income, 1.8 million pounds were derived from capital gains, representing an increase from 1.6 million pounds in the preceding year. Notably, approximately 70% of Sunak's total tax payment can be attributed to capital gains tax on profits realized from the sale of investments such as stocks.

While Sunak is not obligated to disclose details of his income, he voluntarily opted to do so to enhance transparency regarding his personal finances. Notes from Sunak's accountants, Evelyn Partners, clarified that all of the prime minister's investment income and capital gains were associated with a single investment fund based in the United States.

Sunak recently faced criticism for engaging in a 1,000 pound bet with broadcaster Piers Morgan concerning the government's plan to relocate asylum seekers to Rwanda before the next general election. Opposition parties condemned the wager as distasteful, asserting that Sunak's ability to casually place such a sizable bet demonstrated his disconnection from the concerns of ordinary voters.
