So that's almost a quarter. Does that include social security and medicare?
Now what about property taxes (or your landlords property taxes if that's the case, which just goes onto your rent)? Sales taxes? Gas taxes? Alcohol and cigarette taxes? Any of 100 other taxes?
If you aren't brave enough to take on the tax code yourself, how much do you have to waste on accounting services so you don't wind up making a mistake that costs you even more?
Beyond that, what about all the taxes that come indirectly to you through the prices of everything you buy?
And while not technically a tax, every dollar you make is slowly eroded away by inflation.
