I'll take a stab at it, though there are many who are much more knowledgeable about how money works. This is some math.
With four billion dollar bills in circulation, and with each dollar exchanging hands once per day, the .08 sales tax over 640 days would amount to $204,800,000,000.00 (two hundred and four billion, eight hundred million).
There are many taxes. Just about everything you do involves a tax. Gasoline, phone service, water and sewage, power bill, gas bill, car tag, driver license, property tax, excise taxes, tobacco tax if you smoke, liquor tax if you drink, on and on, etc... ad valorem taxes.
Add all those up and probably at least 95% of the dollar is taxed. So let's say with four billion dollars in circulation taxed at .95 with each dollar exchanging hands once per day, the tax over 640 days (lifespan of a one dollar bill) would be:
640 x .95 = $608
$608 x $1B = $608B
$608B x 4 = $2,432B or (two thousand four hundred thirty two billion dollars or
($2,432,000,000,000.00 or $2.432T)
And that's just for the four billion dollar bills in circulation over 640 days. Two trillion four hundred thirty two billion dollars. Add to that the total amount of paper currency in circulation taxed at .95% and it is mind boggling, though larger denomination bills are handled less and don't suffer as much wear and tear in circulation, making their life spans longer. These would be the taxes from bank notes in circulation.
