PookaMustard: Any kind of info about the taxes themselves?
Well let's see what they have in the breakdown...
We have the "sales revenues" of 20,114,000 PLN of which 11,000 PLN are actual products and 20,103,000 PLN is "goods and materials". Not sure what those "products" are, but it's a small portion of GoG's sales.
Then we have the "Cost of products, goods and materials sold". "Cost of products and services sold" comes to 179,000 PLN, so whatever these physical products are, they lose money on them. Maybe T-Shirts or something? Still a small amount. But for all we know its a "loss" for promotional value. "Value of goods and materials sold" comes to 13,308,000 PLN. This is slightly less than 70% so appears to represent the money going back to the developers.
That leaves 6,627,000 PLN "Gross profit from sales". There are 276,000 PLN in "Other operating revenues" but 5,056,000 PLN in "Selling costs"; 1,412,000 PLN in "General and administrative costs"; and 39,000 PLN in "Other operating expenses"
This leaves just a 396,000 PLN Operating profit. They gained 14,000 PLN in "Financial revenues" probably interest income and spent 5,000 PLN in "Financial expenses"
This leaves 405,000 PLN of which they had to pay 143,000 PLN "Income tax" leaving 262,000 PLN or about $67,500 of leftover profit. That makes the "income Tax" roughly 35.3%. Incidentally, the income tax for CD Projekt Red was only about 20.5% but they were likely able to reduce that for losses due to the game development.
