The Biden administration has given a boost to a years-long effort toward global agreement on digital tax rules as negotiators work to strike a deal in the coming months.

Since she took office, Janet Yellen’s Treasury Department has started to reshape the conversation on both elements of the Organization for Economic Cooperation and Development’s two-part plan for a global tax overhaul. Treasury’s proposal to simplify the OECD’s “Pillar One”—which would move more tax revenue to countries where companies have users or consumers, instead of their headquarters—has helped move the talks past a stalemate. And a Biden administration proposal to hike the U.S.’s own global minimum rate to 21% has shaken up negotiations at the OECD over the minimum corporate tax rate, known as “Pillar Two.”

On this week's episode of our podcast, Talking Tax, we hear from Marcus Heyland, managing director of tax at KPMG in Washington. Until March, Marcus was a tax policy adviser at the OECD, where he worked on the Pillar One and Two plans.

Bloomberg Tax's Isabel Gottlieb talks to Heyland about the impact of the new U.S. administration on the global talks, and what issues negotiators are still grappling with as they try to reach an agreement this year.
