Full coverage: Multinationals

Twitter is the latest multinational to reveal a multi-billion intellectual property onshoring in Ireland, suppressing its tax liability here in the process. The company and its rival Facebook are also bracing for the first significant data protection fines under GDPR.

The social media giant is shutting down its Cayman-resident, Irish-registered holding structure after routing over $40 billion through the low-tax scheme over the past decade. It is not yet clear what role Ireland will play in the group's new corporate arrangements.

In a new unified set of proposals, 137 countries have narrowed down the rulebook that will reallocate tax paid by global firms towards those countries where they really make profits. This would mean lower corporation tax receipts for Ireland – yet a number of key pieces are still missing in the puzzle, awaiting political agreement put on ice by Donald Trump this year.

The rising social network is injecting $200 million into an Irish subsidiary and opening new positions for "Pinployees" here as it ramps up business in Europe, following the model established by other Silicon Valley online giants.

For the past three years, many US tech multinationals have been paying their shareholders more money than they earn. The difference came from Ireland, thanks to tax incentives devised by the Trump administration. That cash is now running out.

So many legal punches have landed on Mallinckrodt that it is facing a knock-out blow at any point. While the disputes engulfing the manufacturer of several controversial drugs unfold in the US, they all link back to the group’s corporate structure and intellectual property vehicles here in Ireland.

Forget the paltry €13 billion under dispute in the state aid case between Ireland, Apple and the EU – the Silicon Valley giant continues to repatriate much bigger cash reserves accumulated here, for the benefit of its ultimate shareholders.

Another day, another multi-billion dollar liquidation of a healthy Irish subsidiary by a multinational. Western Digital has taken advantage of US tax breaks to repatriate profits accumulated over the past 15 years by the popular brand of USB drives.

The volume of assets realised through members’ voluntary liquidations has increased nearly 30-fold during the first five months of this year. Why do so many shareholders agree to shut down their company and walk with the cash?

The consequences of the Apple case continue to reverberate, with the recently renamed NortonLifeLock just one of the multinationals changing their corporate structures. After intellectual property transfers and the liquidation of corporate entities straddling Ireland and Jersey, new filings provide the missing piece of the jigsaw in the US online security giant’s Irish move: the consolidation of its global sales empire in a Dublin business park.
