Rishi Sunak paid UK tax of £508,308 on earnings of just over £2.2m last year, according to his latest tax summary.
The document, published by Downing Street, showed the prime minister paid £163,364 in tax on a total income of £432,884.
He also paid £359,240 in tax on around £1.8m in capital gains from a US-based investment fund.
This is the second time he has published details of his earnings since entering No 10 in October 2022.
The first publication, in March last year, covered the previous three financial years, including before he became prime minister.
It follows a commitment he made during his unsuccessful Tory leadership campaign in summer 2022.
Mr Sunak, who worked in finance before entering politics, is thought to be one of the richest MPs in Parliament.
His personal wealth has increasingly been used as an attack line by opposition parties, a trend that could increase during an election year.
In such a swipe last month, Labour leader Sir Keir Starmer said recent mortgage rises "might not sound much" to the prime minister, but that "most people don't have that sort of money".
Mr Sunak hit back by accusing the Labour leader of resorting to "the politics of envy".
Mr Sunak's latest tax summary shows both his earnings and total tax paid have increased from last year, when he paid £432,493 in UK tax on total earnings of around £1.9m.
