If your vehicle was previously registered in Merrimack, you will be mailed a renewal reminder notice at the end of the month prior to your renewal month. You are able to renew in person, by mail or use the E-Reg program to renew your registration online.

The Town of Merrimack has partnered with EB2GOV® to offer payment of vehicle registration renewals over the Internet. Renewing online is generally quicker and easier than renewing in person or by mail; however, your renewed registration is not valid until you receive the actual printed registration which will be mailed to you by the Town of Merrimack. The Town of Merrimack cannot be held responsible for delays due to factors beyond our control nor for any costs you may incur as a result.

EB2GOV®, the vehicle registration renewal service provider, charges a $1.50 convenience fee for each vehicle processed, plus a transaction fee of $.35 for payment processing, in addition to the state and local charges due for renewal. E-Reg does not accept credit cards.
