A motor vehicle excise is due 30 days from the day it's issued. The tax collector must have received the payment, not just mailed (postmarked), on or before the due date. If you haven’t received your bill, or have questions regarding payment, please send an email to the Collector’s Office collector@actonma.gov, or call 978 929-6622.
