The Falls Church City Council gave a thumbs up at its work session Tuesday to support federal legislation to empower the federal Internal Revenue Service to hand over any tax refunds it owes to localities, including the Falls Church Treasurer’s office, in the event a taxpayer in question owes local real estate or personal property taxes at the local level. Falls Church is burdened on average by $650,000 in delinquent unpaid taxes. The measure is strongly supported by City Treasurer Cathy Kaye.
