Filipiak.
Restriction of ability to deduct social insurance contributions paid in another Member State not compatible with EC Treaty
Mr.
Krzysztof Filipiak,
a Polish resident,
carried on an economic activity in the Netherlands as a partner in a Dutch partnership.
He paid obligatory social security and health insurance contributions in the Netherlands in respect of his income.
When he wanted to reduce his tax liability in Poland by the amount of Dutch insurance contributions,
the Polish tax authorities refused,
pointing out that the amount of social security contributions could have been deducted from the assessment base and the tax payable in Poland could have been reduced by health insurance contributions if the taxpayer had paid the insurance contributions in Poland.
Mr.
Filipiak appealed.
In the meantime,
however,
the Polish Constitutional Tribunal ruled that the discussed income tax regulations infringed the principles of equality and social justice embedded in the Polish Constitution.
Nonetheless,
using its competence to indicate the date on which unconstitutional regulations lose their binding force,
the Tribunal deferred the loss of validity of the rules at issue until 30 November 2008.
Uncertain as to the consequences of such a decision,
the national court hearing the appeal requested a preliminary ruling from the ECJ.
The ECJ ruled that Articles 43 and 49 EC Treaty preclude national legislation under which the right of a resident to reduce the basis of assessment by the amount of compulsory social security contributions and to reduce the amount of income tax by the amount of health insurance contributions is restricted to contributions paid pursuant to national law.
In those circumstances,
the primacy of Community law requires that Community law take precedence over conflicting national provisions,
irrespective of the judgment of the national constitutional court which has deferred the date on which those provisions,
held to be unconstitutional,
are to lose their binding force.
