In the US, depending on where you live you could have tax rates of all sorts of kind.
In MN, where I live, taxes can vary from county to county and town to town. In Minneapolis alone sales tax is 10%, but in Brooklyn Center (just west of Minneapolis) the sales tax is 7.53%, yet both cities reside in the same county (Hennepin).
Then you have gas tax. The US Government (Federal) takes $0.183 per gallon and depending on state, it can be anywhere from $0.0895 per gallon (Alaska) to $0.519952 per gallon (Washington)....this is just normal unleaded gas. Diesel generally has a different tax rate.
For me, in MN, between State and Federal income tax it'll come out to roughly 12.5% of my yearly earnings.
Then it also depends on State and city, for what your sales tax is on items. It can also vary by State as to what exactly is taxed, in MN for example, clothing does not have taxes on it, but Wisconsin (just about 45 minutes east of where I live in MN) does tax clothing. Sales tax on items varies a lot, city to city; In Minneapolis, the sales tax is 10%. However, one of the neighboring cities (Brooklyn Park, for example) that's connected to Minneapolis has a sales tax of 7.53%.
Don't forget property taxes - these can vary county to county or even city to city. Hennepin county (where Minneapolis is located) the average property tax on a household is around 1.25% of the home's value.
In all, I'd venture to guess that most US residents pay upwards 30-35% of their yearly earnings back to the Government bodies as taxes in some shape or form.
For me, personally, between Income tax and property tax - that comes out to around 20% of my yearly income that just goes straight back out to the Government.
All that aside, taxes suck. They suck because it's never enough for the hungry governments, always wanting to tax more, more, more! Even after they double/triple/quadruple dip on taxing of things, it's still never enough.
