We all pay a lot more tax than just income tax, but most of us don't employ accountants to work out exactly how much of our income goes on tax. Consider that here in the UK most purchases include VAT. We've already paid income tax on our earnings, but 20% of a lot of or spending also goes to the tax man. Then there are duties on things like fuel and booze. Then we have things like council tax. Taxes paid on things like insurance. All those things add to the tax we pay overall. Add that up and see how much of your earnings actually goes to the public purse.
