Last month, we published briefings considering the 'retaliatory' tax measures (referred to as 'section 899') that were included in the One Big Beautiful Bill Act during the early stages of its passage through US Congress. The measures, targeting certain overseas taxpayers with interests in the US, were removed before the Bill was finalised, alongside the G7 and the US reaching a shared understanding regarding the exemption of US parented groups from aspects of the Pillar Two global minimum tax rules.

The Act itself was signed by President Trump on 4 July 2025. Our US tax team has analysed its tax measures, and a link to their article can be found here.

A further article considering the restriction of tax credits by the Act in connection with Chinese investment in US-based energy storage can be found here.
