The Town of Bedford recognizes standard dates important to those concerned with property assessment.
March 1 (following the final date of tax): This is the deadline for filing an abatement.
April 1 (any year): This is the date of assessment - whatever the state of physical completion or condition your property is in is how your property will be assessed.
For example, if your house was 50% completed as of April 1, 2009, your home will be assessed as 50% until April 1 the following year.
April 15 (any year): This is the deadline to file for an exemption or tax credit for the coming year. This includes Veteran's Tax Credits and exemptions for the Elderly, Blind, Disabled, Deaf, and others.
