The case was initiated by an individual who applied for a tax ruling from the tax office. This individual was trading bitcoins world wide, including Poland.
Any income this individual made was not reported to the tax office. According to his statement, Polish PIT Act regulations should not cover income made by trading bitcoins. He noted that bitcoins were not even invented at the time the Polish PIT Act was enacted.
The tax authorities stated that this individual obtained income from trading property rights which are subject to the income tax scale (18% and 32% tax rates). Including expenses for the purchase of bitcoins in the deducted costs is allowed.
One of the individual's argument was that according to the Opinion of the Advocate General of the EU Court of Justice (case C-264/14), bitcoins should be considered as means of payment. However, according to Polish tax authorities, under Polish law bitcoins cannot be treated as a means of payment, only Polish zloty can be treated as such. Moreover, even if trading bitcoins were to be treated as trading a means of payment (regular currencies), such income would also be subject to the income tax and progressive tax rates.
According to the tax authorities, the 19% flat tax rate relevant for individuals running a business activity does not apply to income made from trading bitcoins. Only the 18% and 32% rates are applicable.
The taxpayer lost in both courts of first and second instance.
