The proposal would introduce a 40% excessive profits tax (EPT) on corporations with over $100 million in turnover. The proposal would allow for a reasonable rate of return (defined as 5% plus the long-term bond rate) on shareholder equity, allows for companies to carry forward credits for years that saw substantial revenue drops, and avoids financial cliffs that discourage smaller enterprises from expanding.

The proposal would start on 1 July 2025.
