RSUs in Spain. There is no RSU as such in Spain: there is a delivery of shares that the law treats as payment in kind, with valuation and timing rules that depend on how your plan is drafted. It is the kind of question where one clause changes the final figure.
Of all the instruments that sit under the umbrella of equity pay, the ESPP (Employee Stock Purchase Plan) is the only one that arrives with a real chance of fitting the exemption in article 42.3.f) of the Spanish Income Tax Act. Not because it has a regime of its own, which it does not, but through a happy coincidence: US ESPPs are usually offered to the whole workforce, and that is precisely what the Spanish rule requires and what discretionary plans for senior staff fail to do.
That said, the fit is not automatic. There are four conditions, one of them lasts three years, and it is the one that breaks most cases. This guide goes through them one by one, with what to check in each and with what happens if the third year is not reached.
How an ESPP works, in two paragraphs
The plan opens subscription periods. During each period the company deducts from your payslip a percentage of salary that you choose, within a cap. At the end of the period (the purchase date) the money accumulated buys shares at a discount to the market price. Many plans add a lookback clause: the purchase price is calculated on the lower of the share price on the first day of the period and the share price on the purchase day.
The economic advantage for the employee is twofold: the agreed discount and, where there is a lookback, the difference between the two prices. And that is where the income lies: the advantage obtained, meaning the difference between the market value of the shares on the purchase date and what was actually paid for them.
The exemption: exactly what article 42.3.f) says
The rule exempts the delivery to serving employees, free of charge or for less than normal market price, of shares or participations in the company itself or in other companies of the group, to the extent that the total delivered to each employee does not exceed €12,000 a year, provided the offer is made on the same terms to all the employees of the company, group or sub-groups of companies.
The detail is in article 43 of the Income Tax Regulations (the IRPF regulations), the implementing regulation that sits under the Act, and that is where the full conditions appear. There are four, and all of them have to be met:
| Condition | What has to be checked |
|---|---|
| Serving employee | An employment relationship in force. Anyone invoicing as an autónomo, a self-employed person, falls outside the exemption |
| Offer on the same terms | To all the employees of the company, and it must contribute to their participation in it. In groups, the condition is measured in the company the employee works for |
| Maximum holding of 5 % | Each employee, together with their spouse or relatives up to the second degree, may not hold a direct or indirect stake of more than 5 % in the company they work for or in any other company of the group |
| Three-year holding | The shares must be held for at least three years |
The Regulations themselves make clear that requiring employees to have a minimum length of service before joining does not breach the condition of an offer on the same terms, provided that length of service is the same for everyone. Nor is it breached by limiting the plan to those who pay Spanish income tax. It is a useful clarification, because almost every ESPP has a waiting period for new staff.
The condition that breaks most cases
The three-year holding period is incompatible with the way most people use an ESPP: buy at a discount and sell straight away to lock in the gain. Anyone who does that cannot apply the exemption, and if they applied it, they have to undo it.
The Regulations say how: failing to meet the holding period obliges you to file a supplementary return (a corrective self-assessment that tops up the original return), with the corresponding late-payment interest, within the period running from the date of the breach to the end of the ordinary filing period for the tax year in which it happens. It is not a penalty, but it is not painless either, and it needs to be in your calendar.
The practical consequence is that the decision to sell is not only a financial one. Selling in month thirty-five and selling in month thirty-seven can differ by quite a lot of money. It is one of the few things in this area over which the client has complete control, and that is why it is worth having the date written down.
How the €12,000 is counted
The limit is annual and per employee, and it is measured across everything delivered. In other words: it is not €12,000 per plan, but €12,000 per year adding up every delivery of shares that fits the rule. If you have an ESPP with two purchases a year and you also receive shares by another route, they have to be added together.
And it is a cap, not a threshold: whatever exceeds €12,000 does not disqualify the rest; it is taxed as employment income in kind. It is worth understanding properly because it is the most common calculation error we see, in both directions.
The calculation, step by step
An example with round figures, purely to show the mechanism. Suppose a six-month period, payroll deductions totalling €5,000, a share price of €40 on the first day and €50 on the purchase day, a 15 % discount and a lookback clause.
- Purchase price: the lower of the two prices, €40, less 15 %: €34 per share.
- Shares acquired: €5,000 divided by €34, which gives 147 shares; the remainder is usually refunded or carried forward, depending on the plan.
- Market value on the purchase date: 147 times €50, which is €7,350.
- Employment income in kind: €7,350 less the €4,998 paid, which is €2,352.
- If the four conditions are met, that amount falls within the €12,000 a year and is not taxed, on condition that the shares are held for three years.
And the figure almost nobody writes down: the acquisition cost of those shares for the purpose of the future gain. When the delivery is exempt, the cost is what was actually paid, €4,998. On sale, the gain is calculated from there, not from the market value on the purchase day. The exemption does not disappear, but part of it reappears as a larger gain on the day of sale, this time in the savings base, the separate band of Spanish income tax where gains are taxed. That is a favourable difference in rate, and explaining it avoids the feeling that something has gone wrong.
Withholding, payment on account and what does not appear on the payslip
A delivery of shares is income in kind, and income in kind carries a payment on account (ingreso a cuenta), not withholding. If the non-exempt part is paid by the Spanish subsidiary, it will normally appear on the payslip with its payment on account and, unless it is passed on to you, that amount is added to the value of the income under article 43.2 of the Spanish Income Tax Act.
The problem arises when the plan is run directly by the foreign parent through a US broker and there is no payer in Spain with the obligation. Then nothing is deducted along the way, the amount arrives in full, and you put the tax in your return yourself. Setting money aside from the purchase date stops being advice and becomes the only reasonable course.
The €50,000 version for start-ups
Since Act 28/2022 the exemption is €50,000 a year for the delivery of shares or participations granted to employees of a start-up (empresa emergente) as defined in that Act, and in that case the offer does not have to be made on the same terms to everyone, although it does have to be made within the company's general remuneration policy and contribute to employees' participation in it. The same Act added its own valuation rule in article 43.1.1.º g) and a deferral of the timing in article 14.2.m), which can reach up to ten years from delivery if there is no stock market listing and no sale of the shares before then.
It is a noticeably better regime, but it applies only if the company qualifies as a start-up under that Act. Checking that before invoking it is part of the job, and in most of the plans from US parent companies that we review, the answer is that it does not.

Before the next purchase window
What should be settled before the next period opens: whether your relationship is employment or a commercial contract; whether the plan is offered to the whole workforce of your company; how large a stake you and your close family hold in the group; how much has been delivered to you this year; and on exactly what date the three-year period for each earlier purchase ends. With those five answers the decision makes itself.
