Where is the Eastern Shore?
Virginia’s Eastern Shore is on a 70 mile long peninsula that stretches from the Maryland state line to the Chesapeake Bay Bridge-Tunnel--- which connects us to Virginia Beach.

Accomack County is divided into districts. Each district assesses a different personal property and real estate tax. Because the County is revamping the way they assess the taxes, please check directly with Accomack County for individual district information.
A few of the larger towns like Cape Charles and Onancock have town taxes but much of the shore is unincorporated.
