> That's how it is in most countries because they're all different entities collecting.
Exactly. I pay city, state, and federal income tax in the US. My city is about 1.5 times the population of Finland, and that's only one of the three different forms of income tax I have to pay. At least that goes through the state, so it's only two departments, but that's again separate from the federal IRS. And that's just income tax, not other taxes I have to account for and pay as well.
The reason it's more complicated in countries like the US, Japan, India, etc. is because they're much, much larger, which requires more complexity to manage - both the size of the government itself and the revenue-collecting departments that need to support it.
If I only had to pay taxes to my city's revenue department and there were no state or federal tax in the US, I can guarantee that the process would be a lot smoother for me as well.
In Poland municipal, state and federal income taxes are paid as a single entry on the tax form. The government then transfers the money to the appropriate lower level of authorities.
So I wouldn't say that most countries differentiate like in the states.
As an additional data point: provincial income taxes in Canada are collected along with federal income taxes by Revenue Canada and then remitted down to the provinces. The sole exception to this being Quebec.
Definitely a peculiarity of the US system being less cohesive than some other countries - and also dealing with far more people and jurisdictions.
Also, I don't think that the size of the country (I think you mean the population, Finland has larger area than Japan), but the amount of bureaucracy given state likes and population is able to handle.
Actually the more population the harder it is keep the different taxes, it would be easier to have a single one and distribute it accordingly from the top.
Side note... when you say your city is 1.5 times the population of Finland, are you referring to the only city in the US with a larger population than Finland?
