In my country, the tax for selling games is -23%
It doesn’t matter what the law in your country is. All that it matters is the trading agreement between the US and your country.
I don’t understand how can it be -35%, and cannot find any information showing how this approximation revenue is calculated.
Are you sure you are reading the numbers correctly? I was under the impression that the maximum tax would be 30%, but I could be wrong.
I’m an individual, not living in the U.S, and have nothing in common with this country.
This is not relevant. You are using a platform that is based in the US, so you have to deal with their laws/treaties with your country.
If you’d rather pay the taxes your country has decided, you can sell them from your own site, which has its own advantages/disadvantages.
Hope that helps
