IP and royalties: how a brand owned offshore collects the profit

Intellectual property is the perfect vehicle for moving profit, and it is easy to see why. A patent has no physical location. Its legal home can be changed by a board resolution. It employs nobody, occupies no warehouse, and its value rests on uncertain future cash flows that even a determined tax authority struggles to dispute. Put the group's patents and brands into a low-tax company, have every operating company pay it royalties to use them, and the profit follows the royalty cheque out of the high-tax country. This is the engine of modern profit shifting.

The basic mechanism, step by step

1. The group's intellectual property is transferred to a holding company in a low-tax place. Done early, when the IP is not yet worth much, the transfer price can be set low (this is the hard-to-value-intangibles problem from the transfer pricing page).
2. The holding company licenses the IP to every operating company in the group and charges them royalties.
3. Those royalties are a deductible cost in the high-tax countries where they are paid, and income in the low-tax country where they land.
4. As the IP grows more valuable, the royalties rise, and the profit pools in the low-tax entity.

Every step is legal. The royalty is a real payment for a real licence. The question is only whether the rate is arm's length and whether the holding company has any genuine substance behind it.

The Double Irish, and why it is gone

The most famous version of this was the Double Irish, used through the 2000s and 2010s by a string of US technology and pharmaceutical groups. It worked by exploiting a mismatch: Ireland decided a company's tax residence by where it was managed and controlled, while the US looked at where it was incorporated. A company incorporated in Ireland but run from Bermuda could therefore be resident nowhere for tax.

Step by step, the classic structure ran like this:

• A US parent put its IP into an Irish-incorporated company that was managed from Bermuda. Under Irish rules that company was a Bermuda resident, and Bermuda has no corporate tax.
• That company sub-licensed the IP to a second Irish company, the real operating hub, which licensed it on to the worldwide operating subsidiaries.
• To stop Irish withholding tax biting on the royalties flowing back, a Dutch company was slotted in between the two Irish companies. The Netherlands' treaty network let the royalties pass through with little or no withholding tax. That slice in the middle is the "Dutch Sandwich."
• Royalties cascaded from the operating companies, through the Irish hub, through the Dutch company, into the Bermuda-resident company, and effectively came to rest untaxed.

The documented endpoint of this is stark. In 2016, one US technology group routed about USD 19.2 billion (around EUR 15.9 billion) of profit to a Bermuda shell company, recorded in Dutch regulatory filings, on an island where it employed virtually nobody.

It is closed. Ireland announced the closure in October 2014; no new entrants were allowed from 1 January 2015; and existing structures were fully phased out by 31 December 2020. A separate OECD deadline barred new entrants to non-compliant IP regimes from 30 June 2016. US tax changes in 2017 reduced the incentive further. We describe the Double Irish in the past tense throughout, because it is past.

What replaced it: patent boxes and the nexus rule

The successor is the patent box: a national regime that taxes income from qualifying IP at a reduced rate, in theory to reward genuine innovation at home. The headline rates look generous against the main corporate rate:

• UK Patent Box: 10%, against a main rate of 25%.
• Ireland Knowledge Development Box: rose to 10% with effect from 1 October 2023, against a 12.5% headline rate.
• Netherlands Innovation Box: 9%, against 25.8%.
• Luxembourg IP regime: around 5.2% effective.
• Belgium innovation income deduction: around 3.75% effective.

The old abuse was obvious: a company could buy in a patent developed elsewhere, license it into a patent box country, and claim the low rate with no real local research. The OECD's fix (the modified nexus approach, agreed 2015, mandatory for new regimes from June 2016, old regimes ended by June 2021) ties the benefit to where the research actually happened. The formula is blunt: the share of IP income that qualifies for the low rate equals the company's own qualifying research spend divided by its total research spend. Outsource all your research to a related group company and you lose most of the benefit. Do your own research and you keep it. Marketing IP such as trademarks and logos no longer qualifies at all; only patents and similar assets do.

Who it is out of reach for

This is a tool for groups whose value sits in patents, brands or software, and who can afford to build and defend an offshore holding structure. A trades firm or a local service business has no portfolio of patents to rehome, no operating companies in other countries to charge royalties to, and no reason to pay for a structure that would cost more than it could ever save. The reduced patent-box rates are, in principle, open to a small UK firm that genuinely patents something, but the cross-border royalty routing that did the real work was always a tool of scale.
