UK government says it'll charge a 20% tax on companies' earnings that are held offshore from April 2019, a move widely seen to be aimed at tech companies

Context & Ripple Effects
This November 2017 move was the opening shot in the UK's campaign against how tech multinationals book profits: rather than taxing revenue where users are, the government went after earnings held offshore, applying a 20% rate from April 2019. Within a year the approach had shifted — the chancellor announced a dedicated 2% digital services tax on profitable tech firms with £500M+ global revenue, and Brussels followed with a proposed 3% EU-wide tax on companies like Google, Facebook, and Amazon.
The significance of the original announcement is clearest in hindsight: it set the political template that culminated in the April 2020 rollout of the 2% levy on search engines, social media, and marketplaces — and in platforms pushing the cost back down the chain, as when Apple raised UK developer fees by 2% and Amazon lifted third-party seller fees by 2% in response.
First-order effects
- Tech companies holding earnings offshore in the UK face a direct 20% charge on those holdings from April 2019, raising their effective UK tax bill without any change to where they book sales.
- The UK Treasury gains a new revenue stream targeted at exactly the multinationals whose structures the existing rules let minimize domestic tax.
Second-order effects
- Because an offshore-earnings tax still leaves room for structuring, the government pivots within a year to taxing revenue directly via the 2% digital services tax — a design that catches companies regardless of where profit is booked.
- Platforms respond by passing the tax through to smaller counterparties: Apple raises UK developer fees and Amazon raises third-party seller fees by the same 2%, converting a tax on big tech into a cost line for app developers and marketplace sellers.
Third-order effects
- If the pattern holds, digital taxation settles into a regime where tax liability follows user location and revenue rather than booked profit — forcing every major platform to decide between absorbing levies or indexing local fees to them.
- Unilateral national taxes like the UK's invite coordination at the EU level, as the Commission's 3% proposal shows, pushing the fight over who taxes digital profits from company structures to intergovernmental negotiation.
The trend: Governments are abandoning attempts to tax tech profits where they are booked and moving to revenue-based digital services taxes, with platforms passing those levies straight through to developers and sellers.
