The weight of evidence for an extraordinary claim must be proportioned to its strangeness.      – Pierre-Simon Laplace

A strange and extraordinary claim is currently doing the rounds in the halls of power and academia. The claim is part and parcel of the emerging school of Modern Monetary Theory (MMT) and is packed in the short meme “Taxes Don’t Fund Spending”.  You read it well. It basically covers the idea that states with their own sovereign money system spend money created out of nothing (and can not go bankrupt) and when people pay their taxes, money gets destroyed.
What we should be looking for as proof for this MMT hypothesis and extraordinary claim is something similar to the overwhelming evidence developed for the other big, strange claim by Post-Keynesians, MMT-ers and Sovereign Monetary Reformers, that “Deposits Don’t Create Loans” or the credit creation theory of money and banking (Werner, 2014). Again, you read it well. The idea is that, when banks originate a loan, they create out of nothing the money by crediting the borrower’s account and destroy money when the principal is paid back. 
Both are similar, strange, counter-intuitive claims which do not accord with folk economics, i.e. the average, popular understanding of money and banking based on the idea that a bank or a state just cannot loan out or spend money it doesn’t have. And it is not only ordinary folk who believe this, but also a majority of politicians and economists.
But the “Deposits Don’t Create Loans” claim has the advantage that it has been proven and / or admitted and / or adhered to now by a vast amount of specialists and financial institutions. 
Below is a list of sources backing that claim. There are economists, social scientists, commercial and central banks, a rating agency and government commissioned research reports all backing the claim. As far as I can tell, the most important ones are Moore (1988), Wray (1990), Graziani (2003), McLeay (2014), ECB (2015) with Werner (2014) providing a dramatic, detailed, empirical proof following the steps in a specific bank when it originated a loan. Quite a weight of evidence, to say the least.
What I miss is a similar amount and strength of proof from diverse corners (national treasuries, budget administrators, tax experts, government economists, etc.) to back up the claim that “Taxes Don’t Fund Spending”. Most writers making the claim refer back to Stephanie Kelton’s 2000 paper, “Do Taxes and Bonds Finance Government Spending?”, in which she presents it as the product of an “intuitive analysis of Treasury operations” (613)*. For me, an ‘intuitive analysis’ is only a first step to evidence and not unlike the formation of a hypothesis, which still has to be tested.
I found only one bank-based economist who, while critiquing MMT, seems to admit that states do, in extraordinary circumstances like war, first spend without concern if the money is already available from taxation or bonds (Every, 2019)**.

Thanks, Govert and AFJM for positing for consideration and discussion one of MMT’s more outrageous monetary-economic postulations – being the one that “TAXES DO NOT FUND SPENDING”. To begin, important that this is NOT anything to do with Post-Keynesian Economics, the bonafide safe harbor for most MMTrs. This is pure Moslerian Economics, and if you think about the history of P-K Economic leadership, the exact opposite of their Philosophy…. to wit, Government MUST spend more in times of downturns, and do so by EITHER deficit spending, OR by “printing the money” . EVERY noteworthy P-K Economist occupied that monetary-economic Fiscal… Read more »
