This Friday is when the Commissioner of Revenue’s office closes the books for personal property taxes or car taxes, and the tax on business personal property. Forms from citizens on changes and updates are due before the tax bills are mailed out as personal property or car tax bills that will be due by October 5, 2016. Vehicles can be added afterwards but the decal will not be on the back of the bill. All vehicles garaged or parked in Falls Church City must have a decal. Vehicles that do not have a current City of Falls Church decal on their windshield are subject to a $50 fine and it is strictly enforced.
