By creating a business that sells resources, such as market gardening.
You created and invested legally (a bank loan) and a party of undeclared money.
After you buy yourself imaginary resources with money from the other world and voila you paid taxes and have a fixed income, it is even possible to buy what will be sold in the other world with the business money
But it is also possible to do without the bank loan, you start slowly, for example making a microgreens production
I'm talking about market gardening, but it could be a restaurant, a laundromat, car wash, sell its services or resources in a way that is difficult to assess the actual amount of sale
in short it's money laundering.
it also works in reverse, you declare less sale to pay less tax and the money you spend it to make discreet purchases (food, fuel, book)
In my country there is the term "travail au noir/black"(black work) is when you sell your services or resources without declaration and that small companies do it a lot, but also individuals, you can sublet your apartment without declaration , even an apartment you rent.
You can sell firewood without declaring it, or even worse, wood that you are not allowed to sell, because you have signed a contract which says that it is for your personal consumption.
