Real Estate Value FY 2026

Following state statutes and Department of Revenue (DOR) regulations, the Board of Assessors completed the FY2026 interim year adjustments of all real and personal property in Medfield.  Using the mass appraisal method, the goal is to arrive at values that are 100% of the market value. Valuations are based on sales, using the last full calendar year before the beginning of the applicable fiscal year. Calendar 2024 sales were used in the Fiscal 2026 value analysis. Market trends may indicate that different property types may change in value more or less than other property types. On average, single-family homes increased in value by 4.7%, and condominiums increased by approximately 8.8%. Apartments increased by 5.9%. The commercial/industrial classes increased by 1%. Individual parcel valuations may vary from the average class increase due to typical differences, data updates and corrections, new construction, and the effect of market trends for specific characteristics. 

Excise Tax Information

Motor Vehicle/Trailer/Boat

All Massachusetts residents who own and register a motor vehicle must annually pay a motor vehicle excise tax. The excise is levied by the city or town where the vehicle is principally garaged, and the revenues become part of the local community treasury.

Excise bills are prepared by the Registry of Motor Vehicles according to the information on the motor vehicle registration. They are sent to city or town assessors who commit them to the local tax collectors for distribution and collection of payment.

Per M.G.L. 60A§1, the vehicle valuation is a percentage of the original Manufacturer's Suggested Retail Price (MSRP). The percentage used is determined by the model year of the vehicle (also known as the designated year of manufacture). Please see the table below for more information. Once a vehicle reaches the 5th year, that vehicle will remain at 10% of the original MSRP for the life of the vehicle. For excise tax purposes, the price paid and the vehicle condition are not considered. If the owner believes the valuation is incorrect, they can contact the Registry of Motor Vehicles at 1-857-368-8000.

Excise Assessed For:% of MSRP
The year before the model year (e.g., 2020 model purchased in 2019)50%
Model year (2020)90%
2nd year (2021)60%
3rd year (2022)40%
4th year (2023)25%
5th and following years (2024 and after)10%

Abatements can be filed if the vehicle was sold/traded/scrapped/totaled or donated during the year in which it is being taxed, or if the owner moved and registered the vehicle in another state. When an abatement is granted, excise bills are prorated by the month.

To process an abatement on your motor vehicle excise tax bill, you must provide documentation to verify the disposition of both the Plate (e.g., was it transferred or turned in?) and the Vehicle (e.g., was it sold, a total loss, etc.?). 

Please be advised that you are not entitled to an abatement by just canceling your registration.

Required documentation to verify the disposition of the Plate (Please submit one):

  • Plate Cancellation Receipt (with VIN#)
  • Registration from your new vehicle showing plate transfer
  • Affidavit of Lost or Stolen Plate (C-19 form)

Required documentation to verify the disposition of the Vehicle (Please submit one):

  • Bill of Sale (with VIN# and signed by both the seller & buyer)
  • Copy of the title (both sides and signed by both the seller & buyer)
  • Purchase Agreement citing vehicle as a trade-in (with VIN#)
  • Insurance Settlement Letter showing you conveyed title to the Insurance Co (with VIN#)
  • Copy of Donation Letter (with VIN#)
  • Repossession Letter (with VIN# and repossession date)
  • Junk Yard Receipt (with VIN#)

Other documentation that may be required, depending on individual circumstances:

  • Registration Form from a new state or country
  • Letter from Commanding Officer (non-domiciliary serviceperson)
  • DV plate registration or a letter from the RMV stating eligibility for the DV plate
  • Insurance coverage selection sheet showing the principal place of garaging

Note:  No excise may be reduced to less than $5.00.  No abatement for less than $5.00 will be granted, and no refund of less than $5.00 will be made.

Incomplete applications will be returned.  When applying for an adjustment, it is the applicant’s responsibility to contact us for a new amount.  A new bill will not be issued.

Sale of a Property

Ownership of a property is based on January 1st of the year before the current Fiscal Year. 

Therefore, Fiscal Year 2026 ownership is based on the ownership as of January 1, 2025. We strive to add the subsequent owners to the bill for mailing purposes. If you receive a bill for a property that you no longer own, please forward the bill to the new owner or return the bill to the Assessor's Office.

The proration of taxes between the buyer and the seller of a property does not involve the municipality.

Assessors' Maps Disclaimer

Assessors' Maps Are NOT Property Line Maps

"Assessors have historically warned visitors to their offices that the tax maps are not property line plans. They are an inventory of all the land ownerships within their municipality, and they approximate the geometric size and shape of individual parcels. Compiled from recorded individual subdivisions and plans of land, the maps are a composite index of a municipality's land records. No certification of the accuracy of assessors' parcel lines is ever conveyed." - John A Hammer, III, Massachusetts Association of Land Surveyors & Civil Engineers

"...the purpose of the maps is only to sufficiently describe the property in question to provide effective notice of which property is being taxed" -Attorney General Robert H. Quinn, January 31, 1972

Solar Legislation

SOLAR Laws have changed and will go into effect on June 24, 2021. Please read the following and refer to the laws noted: New Solar Legislation* sets in place new criteria for a system to be considered tax-exempt:

Produces 125% or less of the energy needed (includes contiguous or other property owned with that community), or is a 25kw or less system. If a system does not meet either of these criteria, the applicant can do a PILOT. An authority to connect notification certificate should be submitted as documentation to prove tax-exempt eligibility unless otherwise noted on the building permit documents. If a system does not meet the exempt criteria or does not execute a PILOT, it would be taxable.

*Chapter 8 of the Acts of 2021 (sections 61, 62, 63, 97, 98) signed March 26, 2021 – goes into effect 90 Days from signing or June 24, 2021

Income & Expense Forms: Commercial Property Owners

Income & Expense forms for FY 2027 were mailed on 2/6/2026 to all Commercial & Industrial property owners. The forms are due by 4/9/2026. The form can be found above in the documents list. All apartment, mixed-use, commercial, and industrial property owners are requested to fill out the information to help determine market values for the community. Those who do not complete the forms are subject to a fine. Even if the property is fully owner-occupied, the Board requests that the expenses section of the form be completed and "owner-occupied" be clearly written on the form.

Tax Rate Information

The tax rate is the town’s budget divided by the total town’s taxable valuation. The town’s budget is a product of Town meeting appropriations required for services, capital expenditures, equipment, etc. These appropriations are adjusted by revenue received by the town and other expenditures. The Tax Rate for the Fiscal Year 2026 is $13.52.

TAX RATE HISTORY

Responsibilities

The Board of Assessors is the local agency responsible for assessing and administering all local taxes provided for by the General Laws of the Commonwealth. The mission of the Board of Assessors is to ‘‘truly and impartially, according to its best skill and judgment, assess and apportion all such property taxes and neither overvalue nor undervalue any property subject to taxation’’ - Massachusetts General Laws Chapter 41, Section 29.

Supervision

The Board is supervised in its administration of local taxation by the Department of Revenue’s Division of Local Services, as provided by Chapter 58 of the General Laws. Among other duties, the Division of Local Services reviews the Board’s assessment procedures every five years to certify that the property is being assessed at its full cash value. Every five years, the Department of Revenue audits the Board of Assessors’ records and procedures for certification. The Department of Revenue’s last certification of the Board of Assessors’ records and procedures was done for the Fiscal Year 2025.
