IN general chapter 7 bankruptsy can discharge irs taxes under the following conditions.
You can discharge (wipe out) debts for federal income taxes in Chapter 7 bankruptcy only if all of the following conditions are true:
You can not discharge a Federal Tax Lien.
So while your personal obligation to pay the tax may be eliminated, if hte lien is already recorded, it remains on the record. So even though the IRS can not pursue you for it, it remains on the record, until it is paid.
So when and if you sell the property on which the lien is attached recorded, the tax lien is paid first.
Since you already have an attorney, I assume he is a tax attorney. Please ask him about the following form: http://www.irs.gov/pub/irs-pdf/f12153.pdf
You are entitled to a due process or equivalent hearing.
If there was already a lien you could still file for the hearing, even though it is intended to be filed for before the lien. BUT, if after the lien you would request an equivalent hearing.
If it is collectible the IRS can periodically review the condition and it can be moved, though this does not happen often, to a collectible status.
They may next file for levy.
The lien can be filed even though the debt is considered at the moment in collectible status. You or your attorney should have been provided a notice of collectible status that also should have stated that a lien may be filed;
If form 53 was not included, then the lien will not be suppressed.
However you can file the following for requesting the lien be withdrawn: http://www.irs.gov/pub/irs-pdf/f12277.pdf
I can not say if they will move to levy. That is a decision made by the person having control of your case.
