The Dutch pension sector is entering the most significant structural reform in its history.
Under the Future Pensions Act (Wet toekomst pensioenen), the Netherlands is transitioning from a traditional defined benefit pension framework to a defined contribution system. By 1 January 2028, all Dutch pension funds must complete this conversion.
This reform fundamentally changes how pension outcomes are experienced by participants. Instead of benefits being primarily determined by collective arrangements, pension outcomes will increasingly reflect investment performance and contributions over time.
For pension funds and the asset managers who invest their capital, this raises an important question.

Dutch pension funds manage some of the largest and most globally diversified portfolios in the world. These investments generate income across many countries, particularly through dividends paid by international companies.
In most countries, when a dividend is paid to a foreign investor, the local tax authority automatically deducts tax before the payment reaches the investor.
However, pension funds are often entitled to recover part of this withholding tax under international tax agreements or domestic tax rules. The important detail is that these refunds are rarely automatic. In most cases, investors must submit formal claims to the tax authorities to recover the excess tax.
If those claims are not filed, the tax remains permanently lost.
For large global portfolios, these amounts can accumulate over time and directly affect net investment returns.
Under a pension system where investment outcomes are becoming more visible to participants, this type of return leakage becomes far more important.
The move to the new pension framework requires extensive operational change across the industry.
Funds must convert existing pension rights into the new structure, update administrative systems, redesign governance frameworks and align investment strategies with the new model. This process, often referred to in the Dutch market as the conversion of accrued rights into the new system, places significant pressure on operational and governance teams.
Asset managers are also adapting reporting frameworks, investment mandates and operational processes to support the transition.
And amidst all this change, there will now be increased scrutiny on investment returns. Foreign withholding tax directly impacts these returns and the process around recovering excess tax is onerous and administratively burdensome. It is becoming more and more common to outsource the management and oversight of this function to ensure the challenges in the process don’t adversely affect investment returns. 

Recovering withholding tax typically requires investors to submit documentation and claims to foreign tax authorities within specific deadlines.
The process may involve:
Because each country has its own procedures and deadlines, managing recovery across a global portfolio can become complex.
When recovery processes are not actively monitored, several things can happen:
In each case, the result is the same: tax that could have been recovered is permanently lost or net returns are not maximized.
Across global portfolios, several types of withholding tax recovery opportunities are frequently missed.
In some European countries, foreign pension investors historically paid withholding tax on dividends even though domestic pension investors were exempt. European legal rulings have since determined that this difference may violate EU principles requiring equal treatment between domestic and foreign investors.
As a result, foreign pension funds may be entitled to claim refunds of withholding tax previously deducted on dividends. These refunds often require investors to submit historical claims directly to the tax authority within strict time limits.
Because the rules are complex and not typically included in standard recovery plans, these refunds are often overlooked.
Certain countries provide full withholding tax exemptions for pension funds, meaning that the correct tax rate on dividends should be zero.
However, claiming this exemption typically requires submitting formal documentation confirming the investor’s pension status.
Without an active reclaim process, these exemptions may never be applied.
In several markets, particularly in parts of Asia, withholding tax recovery processes remain uniquely onerous. As a result, these markets often sit outside the primary coverage of mainstream withholding tax recovery providers and these recovery opportunities are frequently missed.
Over time, this creates a steady stream of unclaimed tax that reduces net investment performance.
Why Specialist Recovery Is Increasingly ImportantManaging withholding tax recovery across global portfolios requires detailed technical knowledge, jurisdiction-specific expertise and continuous monitoring of claim deadlines.
Specialist providers manage the full reclaim process, including identifying eligible claims, preparing documentation, submitting filings and responding to tax authority queries.
Technology also plays a key role in monitoring global portfolios and identifying reclaim opportunities across multiple jurisdictions, helping ensure that deadlines are not missed and documentation requirements are met.

A Natural Moment to Review Recovery ProcessesThe Dutch pension reform represents a once-in-a-generation shift for the sector.
As pension outcomes become more directly linked to investment performance, the industry is placing greater emphasis on the difference between gross investment returns and the net outcomes delivered to participants.
Ensuring that foreign withholding tax recovery is fully captured is an important part of protecting those net returns.
For pension funds and asset managers navigating the transition to the new pension system, this is an ideal moment to review recovery processes and ensure that no sources of return leakage remain unchecked.
