The dry income problem (Dry-Income-Problematik) is what happens when an employee is taxed on shares they receive before they have any cash to pay the tax. In Germany, giving an employee real shares for free or below their value creates a taxable benefit at the moment of transfer, taxed as employment income, even though no money has changed hands and the shares cannot be sold. For years this made genuine employee share ownership impractical and pushed German companies toward virtual schemes (VSOPs) instead. The §19a EStG deferral, expanded by the ZuFinG, is the fix: it postpones that tax until the employee actually has liquidity.
The phrase sounds technical, but the idea is simple and it is the single biggest reason German startups historically did not give employees real shares. If you understand the dry income problem, you understand why VSOPs became the German default and why the §19a regime was such an important change. This page explains the problem itself; the pages it links to cover the solution in detail.
What is the dry income problem?
Dry income is income you are taxed on without receiving any cash to pay the tax with. The German term, Dry-Income-Problematik, describes exactly the situation where a tax bill falls due on a benefit that is real on paper but has not turned into money.
With employee equity it arises like this: an employer gives an employee shares for free or at a price below their market value. The discount, the difference between what the shares are worth and what the employee paid, is treated as a benefit the employee received from the employment relationship. That benefit is taxable straight away. But the employee is holding illiquid shares in a private company, not cash, so they face a tax bill with nothing to pay it from. The income is "dry."
Why does receiving shares trigger a tax bill at all?
Because German tax law treats the value an employee gets from their employer as employment income (Arbeitslohn), and shares handed over below their value are a form of that income.
When an employer transfers shares worth more than the employee pays, the law sees the gap as compensation for work, no different in principle from a bonus paid in kind. Compensation is taxable when it is received, so the taxable event is the transfer of the shares, not some later sale. The valuation matters here: the higher the shares are worth at transfer relative to what the employee paid, the larger the benefit and the larger the immediate tax. For a fast-growing startup, where the shares may already carry a meaningful valuation from a funding round, that upfront bill can be substantial, all of it owed before the employee has earned a cent of actual cash from the shares.
Why did the dry income problem hold back employee ownership in Germany?
Put plainly, it made real shares a liability at the moment they were meant to feel like a reward. An employee handed equity could open a tax bill they had no way to pay, which is the opposite of the motivation the grant was supposed to create.
Faced with that, German companies overwhelmingly avoided giving employees real shares and used virtual schemes instead. A VSOP (virtual stock option program) gives the employee a contractual right to a cash payment that tracks what a shareholder would receive, without transferring any shares, so there is nothing to be taxed at grant and no dry income; tax falls due only when the cash is paid. That neatly sidesteps the problem, which is why the VSOP became the dominant German model (a shift traced in the evolution from V/ESOPs to EIPs), but it also means the employee never becomes a genuine owner and the payout is taxed as employment income rather than as a capital gain. The trade-off between virtual and real-share models is set out in VSOP vs ESOP vs EIP: which model for a German GmbH.
How is the dry income problem solved?
The fix is to break the link between receiving the shares and paying the tax, by deferring the tax to a point where the employee actually has money. That is what §19a EStG does, and after the ZuFinG it can push that point all the way to the exit.
Under §19a, the benefit from receiving the shares is still calculated, but the income tax on it is postponed rather than charged at transfer. By default it becomes due at the earliest of three triggers: a sale of the shares, the employee leaving, or a set time limit being reached. The important refinement the ZuFinG (the Future Financing Act) added is an employer-liability declaration: under §19a Abs. 4a EStG, if the employer irrevocably declares that it will assume liability for the wage tax, the leaving and time-limit triggers fall away, and the tax falls due only on an actual sale. In practice that lets the employee be taxed only when the shares finally turn into cash, which is exactly the outcome the dry income problem otherwise blocks. Together with the broadened eligibility conditions, this is the change that finally made genuine employee share ownership workable in Germany. The full mechanics, including all three triggers, the employer-liability declaration, and a social-security wrinkle that the deferral does not remove, are covered in how employee equity is taxed in Germany, and whether your company qualifies is worked through in the §19a eligibility checklist. Because the details and figures change with the rules and with each company's situation, treat this page as the explanation of the problem and confirm specifics with a tax adviser.
FAQ
What does "dry income" mean?
It means being taxed on income you have received in a non-cash form, with no money to pay the tax. In the equity context, an employee given shares below their value owes tax on that benefit at transfer, even though the shares are illiquid and cannot be sold to cover the bill.
Why are employee shares taxed before they are sold in Germany?
Because German tax law treats shares transferred below their value as employment income, which is taxable when it is received rather than when it is later sold. The transfer of the shares is the taxable event, so the bill can fall due while the employee still holds illiquid stock.
Does a VSOP have a dry income problem?
No. A VSOP transfers no shares, only a contractual right to a future cash payment, so there is nothing to tax at grant and the tax falls due only when the cash is actually paid. Avoiding dry income is a large part of why VSOPs became the German default, though the payout is taxed as employment income rather than as a capital gain.
How does §19a fix the dry income problem?
It defers the income tax on the value of the shares at grant instead of charging it at transfer. The tax becomes due at the earliest of a sale, the employee leaving, or a time limit, but if the employer irrevocably declares it will assume liability for the wage tax, the leaving and time-limit triggers fall away and the tax falls due only on an actual sale. That moves the tax to the exit, when the employee finally has cash, which is what makes real-share employee plans practical. The detail is in how employee equity is taxed in Germany.
