No, Denmark. 33,4% is my total income tax plus social contribution/total income. I pay 47% on the last earned 'dollar'. I believe the highest rate this year is 56% on the last earned 'dollar'.
In total the Danish government collects 44,9% of GDP in revenue, so that is the effective total Danish tax rate, but allow me to be a bit snarky, Denmark had a budget surplus of 3,3% last year, USA had a deficit of about 6%, Danish debt is 30% of GDP, US debt is 125%, The US numbers might be a bit different if their government collected more revenue.
Sorry, I get a bit passionate about this, but many outsiders only hear the part of the story that we pay an awful lot in taxes, if they had some knowledge of Danish society they would know that we get a lot of benefits for our taxes. Sure we moan about taxes as much as other places, but at the end of the day 90% of us know that we get more benefits from our taxes than we would have it we had to pay individually. (No political party that promised massive tax cuts have achieved more than 15% the vote for parliament in my life time)
