Guillaume Pousaz, the billionaire founder of online payments firm Checkout.com, has joined a surge in ultra-wealthy individuals shifting their residence away from the UK amid tax hikes on the nation’s wealthy.

Pousaz, 43, now lists Monaco as his usual residence after previously relocating to the UK from the United Arab Emirates, according to UK registry filings released Tuesday. The Swiss native has a net worth of about $5.6 billion through his London-based technology company, according to the Bloomberg Billionaires Index.
