Supreme Court ruling Box 3

art 40

As the Dutch Supreme court made a
ruling on Box 3 on the 6th of June 2024, today’s article will
present the changes and their consequences on savings and investments taxes.

In the Netherlands, the savings and
investments are taxed on box 3 of the yearly income tax declaration. In 2017, the
Dutch Supreme Court ruled box 3 as it was no longer tenable because it violated
the fundamental rights of taxpayers.

On June 6, 2024, the Supreme Court
of the Netherlands (Hoge Raad) issued several rulings regarding the current
method for calculating income from assets (box 3). The court determined that
the existing calculations violate the European Convention on Human Rights
(ECHR). According to the ruling, only the actual return on assets should be
taxed if it is lower than the notional return. The Supreme Court previously
ruled in 2021 that the old calculation method for box 3 income breached the European
Convention on Human Rights (ECHR). In response, new calculation methods, the
Herstelwet and Overbrugginswetgeving, were developed. However, the Supreme
Court has now found that these new methods also violate property rights and the
ban on discrimination.

Background and Legal Battles

The Supreme Court’s decision arises
from five cases related to the taxation of savings and investments under the
Recovery Act (Herstelwet) Box 3, following the 2021 Christmas ruling. In that
ruling, the court determined that the wealth tax imposed since 2017 violated
European law, necessitating compensation for taxpayers who had overpaid. Under
the Recovery Act, Box 3 taxes were recalculated for those who had timely
objected to their assessments between 2017 and 2020. If the presumed return was
lower than originally assessed, taxpayers received compensation. However,
investors contested this recalculation, arguing that it should be based on
actual returns rather than presumed ones.

Assumed and Actual Returns

The Recovery Act taxed savings and
investments based on presumed returns, differentiating between bank deposits
and investments in securities and real estate. The assumed return for savings
was minimal, reflecting the low interest rates in recent years. In contrast,
the assumed return for other investments was based on a multi-year average,
ranging from 5.37% in 2017 to 6.17% in 2023.

This method often resulted in
significant discrepancies between the presumed and actual returns. For
instance, in 2022, the AEX index fell by 13.65%, but the Dutch Tax Office
presumed a positive return of 5.53% for Box 3 assessments. Conversely, in 2021,
when the AEX surged by 27.75%, the presumed return was only 5.59%.

Financial Impact

The ruling targets the investors who
experienced low returns, particularly during the poor market performance of
2022. However, for the acting State Secretary for Finance, Marnix van Rij
(CDA), the verdict presents a challenge. Van Rij previously estimated that this
decision would cost the government over €4 billion in one-off expenses and
several billion euros annually until a new tax system based on actual returns
is implemented.

Future Implications

The recalculation method used for
the recovery process was also applied to the assessments for 2021 and 2023.
Anticipating widespread objections, the Dutch Tax Office had postponed these
assessments for other investments pending the Supreme Court’s decision.

This ruling marks a significant
shift in the Dutch tax landscape, aiming to align tax obligations more closely
with actual financial outcomes for investors.
