This isn't really as big a deal as it's been made out to be, IMO.
This is Pillar 2 of the OECDs tax reform for corporations.
Pillar 1 is much more interesting, and would require corporations to actually book profits where they are made (so not putting everything through Ireland for example). This will have a much bigger impact imo than this 15% ruling, because right now there are a bunch of tricks you can use to get round any tax rate.
For example, even though Ireland's headline tax rate is currently 12.5%, the effective rate after all the tricks for many US tech cos was <1% to the Irish state.
