The situation
A group stock option plan, uploaded, with employees in Germany, Poland and Spain
A software company in Munich has granted options to 60 staff: 35 in Munich, 15 in its Warsaw development centre and 10 in Madrid. The first tranche vests next spring. HR wants a one-page answer per country on when employees pay tax, and payroll wants to know what it must withhold. One developer moved from Madrid to Munich last year.
The plan runs to 40 pages and the answer turns on a few clauses: whether options can be transferred, what happens on leaving, whether they settle in shares or cash, and who grants them. Then each country applies its own tax point, and the developer who moved needs the benefit split between two countries.
What the research has to settle
The rules behind the answer
- In Germany, exercise is the usual tax point
- Options that cannot be transferred or traded are generally taxed in Germany when exercised, on the difference between the value of the shares and the price paid. Grant and vesting alone do not trigger tax.
- Deferral regimes, on conditions
- Germany allows employees of qualifying smaller and younger companies to defer tax on employee shares, a regime widened from 2024. Poland defers tax under qualifying incentive programmes until the shares are sold, then taxes the gain as capital income. Both depend on conditions the plan and the company must meet.
- Spain treats the benefit as income in kind
- In Spain the benefit on exercise is generally employment income in kind. Reductions for income generated over several years and specific rules for start-ups may apply; the research confirms the conditions for this plan.
- A move splits the benefit
- When an employee works in more than one country between grant and vesting, the OECD Commentary allocates the benefit by the days worked in each country over that period. National rules and the treaty decide how each side applies it.
How it runs in azta
From the question to the document
The question, as you would type it
Attached is our client’s option plan. Options are non-transferable, vest over three years and are settled in shares of the German parent. When are employees in Germany, Poland and Spain taxed, what must each employer withhold, and how is the benefit split for an employee who moved from Madrid to Munich during vesting?

Option plan 2025: tax for employees in Munich, Warsaw and Madrid
Germany. The options cannot be transferred, so employees are not taxed at grant or vesting. The benefit is taxed on exercise as employment income, through payroll. We have checked whether the deferral regime for employee shares could apply; the conditions and our view are in section 2.
Poland. The Warsaw staff are employed by the Polish subsidiary and the options are granted by the German parent. Whether the plan qualifies as an incentive programme, with tax deferred until the shares are sold, depends on the conditions set out in section 3.
Mobile employee. For the developer who moved from Madrid to Munich, the benefit on exercise is split by the days worked in each country between grant and vesting. Spain and Germany may each tax their part; section 5 sets out how double taxation is relieved.
