Dutch Holding + Spain Operating Company: Is It Still Efficient?

The Classic NL BV → Spanish SL Structure

For two decades, the Netherlands BV holding company sitting above a Spanish operating SL was one of the most popular international structures used by multinational groups and high-net-worth entrepreneurs with operations in Spain. The structure exploited a combination of Dutch participation exemption rules, favourable withholding tax treaties, and the Netherlands' extensive treaty network to extract profits from Spain in a highly tax-efficient manner.

The basic logic was straightforward: a Netherlands BV holds 100% of a Spanish SL. The Spanish SL generates operating profits, pays Spanish corporate tax (IS) at 25%, and distributes dividends upward to the NL BV. The NL BV receives those dividends largely free of Dutch corporate tax (thanks to the participation exemption) and holds or re-distributes the profits with minimal further withholding tax exposure.

Post-BEPS and post-ATAD, this structure faces significant challenges — but it has not been killed entirely. Whether it remains efficient depends entirely on whether the NL BV has genuine substance and whether the structure has a valid commercial rationale beyond tax savings.

The Dutch Participation Exemption: The Core Advantage

The Dutch deelnemingsvrijstelling (participation exemption) is one of the most generous in the world. Under Dutch corporate tax law, a Dutch BV that holds at least 5% of the nominal paid-up share capital of another company can exempt virtually all dividends and capital gains from that subsidiary from Dutch corporate tax — effectively a 95% exemption (100% exemption applies in most qualifying cases; the 5% remainder clause applies where the subsidiary is subject to very low tax).

The conditions for the Dutch participation exemption are:

• Minimum holding: At least 5% of the nominal paid-up share capital (not just voting rights or economic interest — the legal nominal capital threshold must be met).
• Not primarily passive: The subsidiary must not hold assets that are primarily low-taxed passive investments (the "oogmerk" or motive test). A Spanish SL operating a genuine business activity passes this test.
• Subject to adequate taxation: The subsidiary must be subject to a realistic tax. Spain's 25% IS rate comfortably satisfies this requirement.

When these conditions are met, dividends received by the NL BV from the Spanish SL are 100% exempt from Dutch corporate tax. This is a genuine and substantial advantage — the profits effectively flow from Spanish IS to the NL BV's balance sheet without further Dutch corporate-level taxation.

Withholding Tax on Dividends: Spain to Netherlands

Under the Spain-Netherlands Double Tax Treaty (2001), withholding tax on dividends paid from a Spanish subsidiary to a Netherlands parent is limited to:

• 5% if the Netherlands company holds at least 10% of the Spanish company's voting stock
• 15% in all other cases

Spain's domestic withholding rate on dividends paid to non-residents is 19% (EU residents may benefit from the Parent-Subsidiary Directive where applicable). The treaty's 5% rate for qualifying corporate shareholders is therefore a significant reduction from the domestic rate.

It is worth noting that the EU Parent-Subsidiary Directive (pre-Brexit) provided for zero withholding on dividends between EU parent and subsidiary companies where a 10%+ holding is maintained for at least one year. This applies to the NL BV → Spanish SL relationship as both are EU companies, potentially reducing the withholding rate to 0% on distributions from Spain to the Netherlands (subject to the anti-abuse rule).

The NL BV as a Conduit: Onward Distribution

One of the traditional attractions of the NL BV holding structure was the Netherlands' lack of withholding tax on dividends paid by the NL BV to its non-EU parent shareholders. Until 2021, Dutch domestic law imposed no withholding tax on dividends paid to shareholders in non-treaty jurisdictions — making the NL BV an attractive conduit for channelling profits to shareholders in locations such as the British Virgin Islands, Cayman Islands, or other offshore jurisdictions.

This changed in 2021 when the Netherlands introduced a Conditional WHT on dividends, interest and royalties paid to low-tax jurisdictions (those on the Dutch "low-tax list" with statutory corporate rates below 9%) or in abusive structures. The Conditional WHT rate is 25.8% (the Dutch headline CIT rate). This has significantly reduced the NL BV's utility as a conduit for non-treaty offshore shareholders.

For shareholders resident in treaty jurisdictions — including the US, UK, Germany and other major economies — the traditional treaty-based approach to extracting dividends from the NL BV continues to apply, subject to the Principal Purpose Test.

BEPS Action 6 and the Principal Purpose Test

BEPS Action 6 introduced the Principal Purpose Test (PPT) — a general anti-abuse rule now incorporated into virtually all modern tax treaties and into the OECD Multilateral Convention (MLI). Under the PPT, treaty benefits (including reduced withholding rates) can be denied if it is reasonable to conclude that obtaining that benefit was one of the principal purposes of the arrangement.

For Netherlands holding structures, the PPT creates genuine risk where:

• The NL BV has no employees, no physical office, and no genuine decision-making activity in the Netherlands
• The structure was established primarily to access the Spain-Netherlands treaty's 5% WHT rate
• The NL BV's directors are the same individuals who manage the Spanish SL (i.e., no independent Dutch management)
• The NL BV serves no commercial function beyond holding the Spanish SL share

If the AEAT or the Dutch tax authority concludes that the PPT applies, treaty benefits can be denied and the domestic withholding rate (19% for Spain) would apply to dividends flowing from the Spanish SL — potentially also retroactively for open tax years.

Substance Requirements: What the NL BV Needs

To withstand PPT scrutiny and to satisfy the Netherlands' own domestic substance rules (Art. 8c VPB — the "schakel" or conduit provisions), the NL BV needs genuine economic substance in the Netherlands. The Dutch tax authority has published substance requirements that indicate what they consider adequate:

• At least 50% of the directors must be Dutch residents or based in the Netherlands
• The NL BV must have qualified personnel to perform its functions
• The board meetings must be held in the Netherlands
• The NL BV must incur adequate salary costs in the Netherlands (a minimum annual cost of €100,000 is often referenced as a proxy, though this is not a statutory threshold)
• The NL BV must have its own bank account in the Netherlands
• The NL BV must have its own premises in the Netherlands

For smaller holding structures (where the Spanish SL earns, say, €500,000–€2 million per year), meeting these substance requirements adds real cost — effectively negating some of the tax savings. This is why the NL BV structure is primarily efficient for larger operations where the transaction costs and substance costs are proportionate to the tax savings achieved.

Spanish CFC Rules: When Spain Attributes NL BV Profits Back

Spain's Controlled Foreign Corporation (CFC) rules (Art. 100 LIS — Ley del Impuesto sobre Sociedades) may require a Spanish resident company (or individual) to include in their Spanish tax base the undistributed passive income of a foreign-controlled entity. The rules apply where:

• The Spanish taxpayer holds, directly or indirectly, more than 50% of the share capital, voting rights, or economic rights of the foreign entity
• The foreign entity's income is primarily passive (dividends, interest, royalties, capital gains from portfolio investments)
• The foreign entity pays less than 75% of the Spanish IS equivalent tax on that income

If a Spanish-resident individual directly controls the NL BV (rather than a Spanish company), the individual CFC rules (Art. 91 LIRPF) may attribute the NL BV's undistributed passive income to the Spanish individual's IRPF return. This can create a significant problem for entrepreneurs who use the NL BV to accumulate investment income without immediate distribution.

The Netherlands' 25.8% corporate tax rate means that Dutch corporate income tax generally satisfies the 75% test — but where the NL BV receives income that is exempt under the participation exemption (and therefore effectively bears very low Dutch tax), the CFC charge in Spain may apply.

DAC6 Reporting Obligations

DAC6 (EU Directive 2018/822) requires tax intermediaries (lawyers, accountants, tax advisers) and, in some cases, taxpayers themselves to report certain cross-border tax arrangements to their national tax authorities. The Spanish implementation (Orden HAC/342/2021) requires reporting where an arrangement:

• Uses the Spain-Netherlands DTT to reduce withholding tax (Hallmark C1)
• Involves circular fund flows with no substantive economic activity (Hallmark E)
• Involves a structure designed to convert income from one type to another to access lower rates (Hallmark B)

Many NL BV holding structures will trigger at least one DAC6 hallmark. DAC6 reporting does not invalidate the structure — it is an information-sharing mechanism, not an anti-avoidance rule — but it puts the structure on the AEAT's radar and increases the probability of a review or inspection.
