I work till around mid July to pay all my taxes including state , fed, and property taxes... However, it all depends what you mean by how long.. I pay about $10,000 in taxes , not including sales tax, gas taxes, tax on my electric bill to help " the poor", and likely a host of other taxes. I make about $1,000 a week, so if you look at it how long I work to pay my taxes,, then it's about 10 weeks,,, or 20% . There are hidden taxes we hardly see however.
