Interesting, how does that work? Can a bank create money to pay its own taxes? That sounds too convenient...
A bank creates money when it borrows you money that isn’t fully backed by saving account(s). See https://en.m.wikipedia.org/wiki/Fractional-reserve_banking, which, a.o. says:
”Because banks hold reserves in amounts that are less than the amounts of their deposit liabilities, and because the deposit liabilities are considered money in their own right, fractional-reserve banking permits the money supply to grow beyond the amount of the underlying base money originally created by the central bank.”
The amount by which a bank can do that is regulated, and, in the end, under control of the central bank. The central bank won’t be involved in every minor fluctuation of the amount of money in circulation, though.
That was true in the days of the gold standard (https://en.wikipedia.org/wiki/Gold_standard), but nowadays, i don’t think it is true anymore.
You can’t bring your 20$ bill to the government and get goods in return whenever you want to make such an exchange.
Also, a lot of money gets created by banks, not the government (in the USA, all the money, I think. Isn’t the Fed independent?)
