if by blacklisted, you mean fined and posible jail time for tax evasion, then yes you will get blacklisted, and depending on how much you are not reporting, you can be fined many times more than the origanal amount you would have hed to pay had you filed, but can be sent to jail or posibly even prison for numorous months or years!!!! so my suggestion to you, is to pay and file your taxes on time every year, if you have to pay in to the government or state every year, you can always work out a payment plan to pay in small payments to keep yourself out of trouble with the state or federal governments, even though these entities are crooks, they will always win in a court of law, after all they own the court system...
this info is for the laws in the U.S.A. only, i have no idea about the tax laws any other place in the world!!!!
hope this helps you to make the right decision, and file and pay your taxes...
