The link you provided is the web page of the interest group I mentioned. They will literally try any trick in the book to get that number up, including adding a bunch of things that aren't even taxes, a boatload of things they call "quasi-taxes" with numbers presumably pulled from their ass, and adding expenses your employer incurs only to subtract them again immediately. Anything to get that percentage number up.

But even they don't even call the resulting number "tax burden" - that'd be transparently stupid. They more generally call it a "burden ratio" (Belastungsquote).

Just to give you an idea of how ridiculous their calculations are: If my wages are 90k in Germany, they do their calculations as if I earned ~105k just so they can immediately subtract the entire 15k again and call it a burden (for expenses my employer pays on my behalf). Does this still sound like something you can easily compare one country to the next and draw useful conclusions from? Of course not. In the next country it might come from an interest group with a different goal, a government calculation, or a Fox News writer.

> You have to add in all the other taxes as well. For example VAT, gasoline, and property taxes are significant. That's generally what tax freedom day is meant to mean - when an average citizen is done paying all taxes.

What you're trying to get at - hopefully because the alternative is a nonsense number with no purpose other than being a fun fact supporting a discussion about degrees of individual autonomy in modern societies - is called discretionary income, and it's only meaningful when adjusted for cost of living and compared across similar living situations.

Aren't you talking about social contributions that your employer is forced by law to pay on your behalf? You realize that if this was not in place, those money would go directly to you since your salary is whole sum your employer is paying towards your employment? Doesn't seem you grok it fully from your words.

I am not claiming if its good or bad (dramatic global financial changes will test viability of all these systems rather well in upcoming years, I'd expect many people will be unhappy when their naive views hit reality of numbers). I am outside of such system, in mostly private social system in Switzerland (aka I save for myself, mostly) and wouldn't want it any other way.
