"Tax is one of the smartest investments you can make." That's Professor Chris Harrop's promise to companies, and his new tax funded impact model proves it by helping quantify how paying tax is not only good for their businesses, but for the economies they're operating in, and of course for people and society.

Plus: Why have OECD countries just bent the knee to Donald Trump and given up their
sovereign rights to tax US businesses operating within their own borders? Naomi Fowler speaks with Zorka Millin of the FACT Coalition about how US companies now have an exemption from the global minimum corporate tax. Also, Zorka discusses some progress on the Corporate Transparency Act's rollercoaster journey in the US towards setting up a beneficial ownership register - a court ruling has pushed things a little further forward, which is good news since the United States is the world's biggest financial secrecy offender. Now some of the watering down of the act needs to be reversed...

Featuring:

Zorka Millin of the Financial Accountability and Corporate Transparency Coalition, Chris Harrop, Professor of Sustainable Business at the Huddersfield University Business
School in the UK, non-executive director with the Fair Tax Foundation, a founding partner of the Human Centre, and lawyer Mary Inman of Whistleblower Partners. Hosted and produced by Naomi Fowler with Leo Schick.
