Free advice in a matter like this is worth exactly what you paid for it. See a tax attorney asap. Get council. They will understand what laws apply. There may be legal protection under the law that will spare you a great deal of misery. Do not delay another minute, your very freedom is at stake. Better to reach out and establish a functional rapport than wait for a knock at the door. Good luck...
“See a tax attorney asap.”
Isn’t that free advice? (and not necessarily good advice as my experience in working with many many tax attorneys over 35 years of handling IRS audits and fed tax court cases is that the attorneys are good at the big picture but do not have the time and would be wasting your money to handle the details. It would be like using a deer rifle to shoot a rabbit... most likely is overkill unless it is a very big rabbit or that is the only gun available. People waste a lot of money out of emotional fear that the problem might be bigger than it actually is. Quantify the problem first!)
This is why the IRS has brought so many actions, including criminal actions against the folks advertising to handle your tax debt if it is over $10,000. They were just ripping off people who were down and out. You may notice that the old tax help advertisers are no longer in business.
