Huh. Taxed on what basis? You buy it with your already income taxed money, and the company reports it as income which is then again taxed? It’s like buying a gift voucher. Or maybe foreign currency, but usually you are only taxed on the gains once you sell them, but you can’t sell in-game currency… What else would you like to tax? What would you even audit? Hey tax authority, I have 3 million gold coins, 2486 diamonds and 4 speed ups in clash of clans, do you want screenshots? Do I just send you 10% to your clan?
In-game currency is annoying and bad, but I don’t get what you want to do here.
I’m a florist. People understand what I do, they usually just don’t think it’s worth doing or paying me for my labor.
