How are bitcoin trade profits taxed in Poland? I turned some profit when trading bitcoin on Bitcurex - likely enough to exceed the tax-free income value in Poland. That likely would mean I should declare the profits in my tax return forms and pay income tax on them, but I have no clue how they are classified and taxed in Poland. Do I have to pay tax on my profits? If so, how do I calculate how much to pay? Where do I fill it in, on my PIT forms?
Although I am no polish or live in Poland, I would recommend to claim it as you would do for a investment. If the government finds out your not paying tax, the consequences are far greater than the tax you would pay.

If your not sure then just call the tax department of the Polish government.
