Stock options under EU Inc

The single most consequential — and most contested — pillar of EU Inc is how employee stock options are taxed. Here is what "taxed on sale, not grant" actually means, and why it is at risk.

The problem EU Inc is trying to solve

Across Europe today, ESOP rules are a patchwork of 27 regimes. In many member states, employees are taxed when options are granted or exercised — before they have any cash, and sometimes on paper gains that never materialized. This makes equity less attractive than cash, and makes it hard to hire the best talent against US competitors (where equity is the standard incentive).

What "taxed on sale, not grant" means

  • Taxed on grant/exercise (the bad status quo in many countries): you owe tax the moment you receive or exercise the option, on a value you have not realized.
  • Taxed on sale (what EU Inc proposes): you owe tax only when you actually sell the shares and receive cash — aligning the tax event with real liquidity.

The second is dramatically more founder- and employee-friendly, and it is the reason the ESOP pillar is a "non-negotiable" for the EU–INC coalition.

The safe-harbour valuation

To make tax-on-sale work, you need a way to value the shares at grant (so the taxable gain on sale can be computed later). The proposal includes a safe-harbour valuation rule — a pre-agreed, simplified way to value early-stage shares without expensive, contested appraisals. The US analogue is the 409A valuation, and the practical question for founders is whether Europe builds its own workable equivalent.

Status: the standardized ESOP (pillar 4) is currently under threat in the negotiations. If it is diluted — for example, national opt-outs — the whole "one standard" promise for equity falls apart, and founders are back to 27 ESOP regimes.

What is actually at stake

If the ESOP pillar survives intact:

  • European startups can issue one ESOP format understood by hires in every member state.
  • Employees pay tax only on real liquidity, narrowing the gap with US compensation packages.
  • Founders spend less on bespoke legal work and more on hiring.

If it is diluted, equity in Europe stays fragmented — and one of EU Inc’s main advantages is lost. The diagnostic scores the ESOP situation against where the pillar stands, and the tax guide explains the broader picture.
