I find OECD report on average labour taxation the best comparison, though limited to fewer countries:
Also keep in mind in most developed countries there are major differences between average effective tax rate paid by single earners and family with dependents.
For example a country with 20% tax and free schools could have lower "effective tax" than a country with 10% tax where you have to pay tuition.
It may be better to look at government spending in proportion to the GDP and ignore how the government actually got this money. Even when the government lends money -- that's just money your grandchildren will have to pay back through taxes (with interest).
The gov-spending/GDP ratio should be a better indicator of the 'tax' climate.
But even that, could be very misleading. If you need a lot of high educated staff, you would prefer a government that spends that money on free high quality class-free education. If you are an oil company, you might actually prefer that money being spend on a war machine.
I.e.: A source giving real percentage of taxes paid for each anual income. Why: because these here at the maximum taxes. These are pretty accurate for lower income people since they don't have many ways to avios paying taxes, but when you get to the very rich the number changes completely, they use a number of loopholes to avoid paying their taxes.
It would be interesting to know what percentage of tax payers are in each bucket for the countries that have large ranges.
I'm always surprised to see how just how much misinformation and misconceptions there are in regards to the US tax system.
It's even more pronounced with Russia and China (and nowadays Turkey, with Hungarian aspirations to join the club): Fiercely capitalistic economies* in an almost complete absence of other civil liberties.
For NK, I doubt that a comparison makes any sense, considering how far removed it is from other countries' societies. How do you account for widespread forced labor? What's the real value of any income they get if part of it is in quotas for food, and most prices are subject to change at a moments notice when PJ thinks it's a good idea or toilet paper reserves are running dry?
*as long as it doesn't come into contact with political realm, and sometimes obscured by an additional kleptocratic layer.
Since the state controlled most of the means of generating capital and manufacturing (and hence profited directly from any goods they produced), direct taxation was unnecessary direct taxes were less than 10% of the government revenue of the USSR and most other soviet/communist states.
There were high taxes levied on some imports, as well as on foreign corporations there were also often export taxes on goods that were set for export that were not directly produced by state owned enterprises.
