Dutch Supreme Court dismissed tax appeal regarding incorrect income tax and social security premium assessments.

The Supreme Court of the Netherlands dismissed the cassation appeal filed by a taxpayer against the Court of Appeal's decision on income tax and social security premiums. The taxpayer argued that the assessments were incorrect, but the Court of Appeal had already rejected these claims based on the tax authorities' calculations. The Supreme Court upheld the lower court's ruling, confirming that the assessments were legally sound and the taxpayer's arguments failed to meet the required standard of proof.
