The priority of these claims and liens is determined by the date and time of recording, docketing, levy, or bona fide purchase.
If a taxpayer executes an assignment for the benefit of creditors or if insolvency proceedings are instituted against a taxpayer who owes a tax, the tax lien attaches to all real and personal property of the taxpayer as of the date and time the taxpayer executes the assignment for the benefit of creditors or the date and time the insolvency proceedings are instituted. In these cases, the tax lien is subject only to a prior recorded specific lien and the reasonable costs of administering the assignment or the insolvency proceedings.
