I like this advice. Moral of the story: have a good accountant or tax lawyer.First of all, do you know for sure that you owe them or is it something there just saying? Because my late husband and I used to get tax bills that actually said that we owed them $17,000 and it was just escalating. And we knew that it was impossible but we didn't know how to get out of it. The IRS put a Levy on our bank account and we were freaking out.
So we just so happen to find an accountant that went to the same church as we did and told him the situation and he asked us to sign a paper to give him full control. He made one phone call in front of us and the Levy was off instantly. Then he asked my husband if he could show a few receipts from prior years and yes he had them and I know you will not believe the outcome... the IRS ended up having to write us 4 checks, we owed them nothing! You do need a good accountant.
Let me know if you want his name and number.
