Denmark’s tax authority, SKAT, has reversed its interpretation of Article 30(3) of the Canada-Denmark Double Taxation Convention (DTC), recognizing that Canadian Master Trust Funds whose beneficiaries are trusts governed by deferred profit-sharing plans (DPSPs), pooled registered pension plans (PRPPs), or registered pension plans (RPPs) are entitled to the treaty’s full 0% dividend withholding tax exemption.

The decision is significant because it represents Denmark’s acceptance of a look-through approach for Canadian pension pooling structures. For Canadian pension funds that invest, or previously invested, in Danish equities through Master Trust arrangements, the financial consequences could be substantial.

The reinterpretation follows litigation initiated by Taxology and its partners on behalf of Canadian Master Trust clients, along with consultations between SKAT and the Canada Revenue Agency (CRA) under the treaty’s Mutual Agreement Procedure provisions.

The development also mirrors a similar shift involving US 81-100 Group Trusts. In March 2025, Denmark and the United States entered into a Competent Authority Arrangement confirming that qualifying US pension pooling vehicles could access treaty pension exemptions on a look-through basis. The Canadian result follows the same underlying logic, although it was achieved through competent authority consultation rather than a formal bilateral arrangement.

Canadian pension funds that held Danish equities through Master Trust structures and received denied or partially denied withholding tax reclaims should review their positions carefully. Historical claims that remain within Denmark’s limitation period may now be recoverable in full.

The Canada-Denmark Treaty Framework

Article 10 and Article 30(3)

The Canada-Denmark DTC establishes several withholding tax rates for dividends paid by Danish companies to Canadian investors.

Under Article 10, Denmark’s domestic dividend withholding tax rate of 27% is generally reduced to 15% for qualifying Canadian treaty residents.

Article 30(3) goes further by providing a complete exemption for certain Canadian pension organizations. The exemption applies where dividends are paid to a Canadian organization constituted and operated exclusively to administer or provide benefits under one or more pension, retirement, or employee benefit plans, provided several conditions are met.

The organization must be:

1. the beneficial owner of the shares;

2. hold the shares as an investment;

3. be generally exempt from tax in Canada;

4. and not own more than 5% of the capital or voting stock of the Danish company paying the dividend.

The relevant class of shares must also be regularly traded on an approved stock exchange.

The policy behind the exemption is straightforward: pension funds investing retirement savings across borders generally should not suffer source-country withholding tax on investment income. Similar pension exemptions appear in Denmark’s treaties with the United States, the United Kingdom, and the Netherlands.

Why Canadian Master Trusts Created a Problem

A Canadian Master Trust, sometimes referred to as a commingled trust or investment trust, is a pooled investment vehicle established under provincial trust law. Its purpose is to aggregate the assets of multiple pension plans so they can access investment opportunities and economies of scale more efficiently.

The difficulty arose because the Master Trust itself is not technically a registered pension plan, as it does not appear on the CRA’s registry of pension plans, does not have its own registration number, and does not independently qualify for tax exemption under section 149(1)(o) of the Canadian Income Tax Act.

Instead, the underlying participating pension plans are the tax-exempt entities. Each RPP, DPSP, or PRPP that invests through the Master Trust is individually registered, generally exempt from Canadian tax, and each participant holds units in the trust proportionally.

Economically, the structure functions entirely as a pension investment conduit. The units are held exclusively by pension entities, the investment mandate is limited to pension asset management, and all economic benefits ultimately flow to pension beneficiaries.

However, SKAT’s original position focused on the entity directly receiving the dividend. The question, in SKAT’s view, was whether the Master Trust itself qualified as an organization “generally exempt from tax in Canada.” SKAT concluded that it did not.

Because the Master Trust was not independently recognized as a registered pension plan, Denmark denied access to the 0% exemption and instead applied the ordinary treaty rate of 15%, or in some cases the full domestic 27% rate.

That interpretation created a significant mismatch: if the same pension plans had invested directly in Danish shares, the full exemption would have applied. The higher withholding tax burden resulted solely from the use of a pooled investment structure.

The Litigation and SKAT’s Reversal

Taxology challenged SKAT’s interpretation by arguing that the treaty should apply on a look-through basis.

The core argument was that where every beneficiary of the Master Trust is itself a qualifying tax-exempt pension arrangement, the “generally exempt from tax” requirement should be assessed at the level of the underlying investors rather than only at the intermediate trust level.

SKAT subsequently consulted with the CRA under Article 25 of the treaty, which governs the Mutual Agreement Procedure. Following those discussions, SKAT reversed its position and accepted that Canadian Master Trust Funds whose beneficiaries consist of qualifying pension entities satisfy the requirements of Article 30(3) and are entitled to the full 0% withholding tax exemption on Danish dividends.

Why the Look-Through Interpretation Makes Sense

One of the key treaty requirements is that the organization be constituted and operated exclusively to administer or provide benefits under pension or employee benefit plans. Canadian Master Trusts satisfy that condition directly, as their governing documents restrict them to pension-related investment activity, and they cannot accept investments from non-pension sources.

The more difficult issue involved the “generally exempt from tax” requirement.

SKAT’s revised interpretation recognizes that a Master Trust whose units are entirely held by tax-exempt pension entities should itself qualify for treaty purposes. That approach avoids an outcome that would otherwise be difficult to reconcile with the purpose of the treaty.

The beneficial ownership analysis also supports the revised position. The Master Trust is typically the legal holder of the Danish shares and the direct recipient of the dividends. However, under Canadian trust law, the beneficial interest in the trust assets belongs to the participating pension plans rather than the trustee itself.

In substance, the Master Trust functions as a fiduciary investment conduit for the underlying pension investors.

The Parallel With US 81-100 Group Trusts

The Canadian development closely resembles the earlier resolution involving US 81-100 Group Trusts.

In that context, Denmark had also taken the position that pooled pension investment vehicles were not themselves qualifying pension entities under the treaty. The issue was ultimately resolved through a March 2025 Competent Authority Arrangement confirming that 81-100 Group Trusts could qualify for treaty benefits where they operated “exclusively or almost exclusively” for eligible pension beneficiaries.

The Canada-Denmark treaty uses slightly stricter language, requiring the organization to operate “exclusively” for pension purposes. Still, Canadian Master Trusts composed entirely of RPPs, DPSPs, or PRPPs clearly satisfy that requirement. More broadly, the decision reflects a wider international trend toward applying pension treaty provisions based on economic substance rather than rigid entity classification.

Practical Implications for Canadian Pension Funds

The reinterpretation creates immediate opportunities for Canadian pension investors that previously suffered excess Danish withholding tax through Master Trust structures.

Affected investors should review historical Danish dividend withholding positions, reassess denied or partially granted refund claims, and determine whether open limitation periods remain available for recovery.

The decision may also have implications beyond Denmark. Other jurisdictions with similar pension treaty provisions may increasingly adopt a comparable look-through analysis for pooled pension investment vehicles.

For pension investors operating internationally, the case is another indication that tax authorities are becoming more willing to recognize the economic reality of pension pooling structures when applying treaty benefits.
