there is no actual law that you have to pay, its really a volinatry system.. Problem is they will hold you in prision for 40 years while you try to prove that.
No you wont come on, stop being melodramatic. I know of one instance where a person didnt pay taxes on 2 million and only got 2 years in the joint. They will, however; levy a lean which is worse. Then it screws your credit for 10 years from the time you pay off the lean. With that on your record no mortgage company will dare touch you.
