At the time of foreclosure, the tax collector should send a copy of the lien certificate to the IRS at the same time it is recorded with the registry of deeds. The municipality should also send a copy of the notice of impending foreclosure to the IRS itself. The way to extinguish an IRS lien against the property is by the municipality sending the IRS a copy of a notice pursuant to 26 U.S.C.A. § 7425. Samples of the notice can be found on the IRS website (IRS publications 786 and 4235). The statutory notice will extinguish the IRS lien as long as it is sent to the IRS by certified mail at least 25 days prior to the date of automatic foreclosure. It is best to send the section 7425 notice to the IRS at the same time that the 30–45 day notice of pending foreclosure is sent. The IRS has a redemption period of 120 days following the date that the municipality takes title through the foreclosure process. Thus, it would be wise to wait the 120 days after taking possession before selling the property.
While it is not clear that the IRS would foreclose on a lien against property that is no longer owned by a taxpayer, but rather is owned by the municipality, obviously clean title to the property is preferred, and the sending of this notice is the way to achieve that.
