I dont know anything about state taxes. If you can hit the 3 yr mark from last assessed. Then they can be DC'ed. Its the only reason I filed BK. After 14 yrs they finally came after me for garnishment. Had a lien for yrs. Once the BK7 no assest DC was done. The lien/back taxes was so old I got released and they fell off my reports even before the new CRA reporting guidelines. I believe the IRS will file a lien first before they do the garnishment and other collection procedures if I remeber correctly.
My posts are JMHO. I DO NOT claim to be a FICO expert. Just sharing my experiences from rebuild to recovery after BK DC. My siggy is not to brag at all. Just to show fellow members what can be accomplished when you do it right and play the FICO Credit Game.
