It's pretty much how business law already works over there. The tax system is set up in such way that it's impossible for a business to pay all taxes and still turn in a profit.

So all businesses cheat on their taxes. Majority of business deals are made with a huge cash component - if a contract is for 100K, it's written for 30K and 70K is paid in cash under the table. Until they run afoul of the government, it's considered to be ok and nobody gets in trouble.

However, the minute government wants to acquire or close that business, they accuse the business of tax fraud, hit them with huge fines, close them down, throw the founders in jail, etc.
