Your post sounds like you have not filed income taxes for 7 years????? If this is the case the IRS will not deal with you, until you pay the bulk of your taxes. That will mean garnishment of your wages, and the forced sale of your house, and all your assets.
JK Harris is good at what they do, but they are not miracle workers. You should have saved the 8000.00 that you paid them, and gave that money to the IRS.
They probably tried to get the IRS to settle with you, but the IRS wants your assets, and rightly so. No Taxes for over 7 years. Dude you could be looking at jail time.
Just remember,in the future PAY YOUR TAXES, we dont want to, but the GOVERNMENT WILL FORCE YOU.
