Has anyone used Back Tax Rescue to help them?

Yes I did. I was getting calls and collection letters from the IRS. I owed $42,000 to the IRS; based on the letters they sent me. The first thing Back Tax Rescue did for me was file the tax returns i did not file. I told them i wasn't able to file because i lost my job at the time - it was really hard. I am now just waiting to see if the IRS will agree to a payment plan. Now with finally filing it shows i only owe $4300 hundred dollars. My brother law is using them as well; after what they did for me i figured they could help him too. I would recommend them.
