What kind of example does that set for the small business people in the country?
The politicians are massively corrupt in Germany (Berlins mayor lost her doctor title because she cheated and then she became mayor).
I can understand it when small business operators also want to avoid taxes - as the banks regularly also do.
In Belgium since last summer you have to accept at least 1 form of digital payment now. Some places try to bypass it by only accepting some obscure creditcards.
Many European countries have made certified/financial cash registers mandatory to combat this, but I believe in Germany they are still optional.
The issue is so widespread, I remember hearing that the tax authorities fully expect some industries to only report parts of their income and have made peace with that fact. Mandatory reporting would apparently disrupt the economy too much...
Cash doesn't have any of those issues, its amazing. That's why governments hate it! (literally!)
The capacity to not pay taxes is a very important tool of civil disobedience, just like protesting in a public street.
Sure, they'll send collections after you and get the money one way or another, but it's not like a bank account is going to make any difference there. They'll force open your door and sell your stuff if you make it hard enough for them, not sure how that's better.
I'm sure the "taxation is theft" crazies will have some legal fanfiction about how the government can't just take your money if you only use cash but in practice you're only getting yourself into trouble for no good reason if you try to commit tax fraud.
It's possible that I may have dodged a few dollars of taxes when buying crap out of China when they put a fake bill in the outside to dodge import taxes, but I don't believe there's a way for a consumer to manually pay those once the package has crossed the border undetected. These days they've changed the system, though, so I don't think it would happen again.
I will pay you 1000 dollars for the right of taking every single asset you have if at any point it is proven you haven't paid all your corresponding taxes.
This is free money for you and your sense of justice. I can send a contract as soon as today.
