Hoge Raad dismissed tax appeal regarding incorrect income tax and social security premium assessment by lower courts.

The Supreme Court dismissed the cassation appeal filed by the taxpayer against the Court of Appeal's decision on income tax and social security premiums. The taxpayer argued that the lower courts incorrectly assessed their taxable income and calculated the premiums based on erroneous figures. The court found no grounds for cassation as the lower courts had correctly applied the relevant tax laws and facts were established without error.
