This is the annual list of Corporations Subject to Taxation in Massachusetts, issued pursuant to General Laws c. 58, § 2
Annually, the Division of Local Services provides a comprehensive listing of corporations for Massachusetts’ assessors to 
be used for local tax assessment purposes. We publish this list solely on the Internet (
) to facilitate keyword and community based searches.

The list of Corporations Subject to Taxation in Massachusetts provides a listing of legal entities subject to tax or excise 
under G.L. c. 59 (local property tax), 60A (motor vehicle excise) or 63 (corporation taxes) as corporations based on their 
1) registration as corporations with the Secretary of State or 2) filing returns, certifications or other notices with the 
Department of Revenue (DOR) indicating that they are corporations or will be filing corporate returns in Massachusetts 
as of January 1. This listing can provide useful information to cities and towns about the taxable status of business 
entities located within a community. The contents of the list are drawn from data compiled and maintained by DOR.

This resource is divided into three sections, 1) corporations, 2) financial institutions, and 3) insurance companies. The 
corporations list includes business corporations that are classified as manufacturing or research & development after 
filing an application for that classification with DOR. The financial institutions and insurance companies are listed 
separately under their own section headings because they are taxed differently from business corporations. 
Corporations included in these lists that are not classified as manufacturing or research & development have been listed 
based solely on registrations, certifications, returns or other notices they filed; such inclusion does not indicate DOR’s 
approval of any applications for classification or other review and determination of their corporate status

For purposes of local property tax exemptions under G.L. c. 59, § 5, cl. Sixteenth, any unlisted unincorporated business 
entity that (A) is treated as a corporation for federal income tax purposes as of January 1 and (B) is treated under G.L. c. 
63 as a business corporation subject to tax under G.L c. 63, § 39 (including a manufacturing or research & development 
corporation) is entitled to the applicable local property tax exemption under G.L. c. 59, § 5, cl. Sixteenth (2) or (3) for a 
business for a manufacturing corporation (if classified as manufacturing), or for a research & development corporation 
(if classified as research & development and located in a community that has accepted the local option) as of that date. 
See Bulletin 2013-06B , Local Option Exemptions for Research and Development Companies and Disregarded Limited 
Liability Companies. Unincorporated entities that are potentially so treated include those with LLC (Limited Liability 
Company), LP (Limited Partnership) or LLP (Limited Liability Partnership) in their names. Note that entities that are taxed 
as financial institutions, insurance companies, or utility corporations, or otherwise under G.L. c. 63, § 2, 2B, 20-29E, 38B, 
52A, or 58 are not treated as business corporations subject to tax under G.L c. 63, § 39 and thus are not entitled to these 
particular exemptions. See G.L. c. 63, § 68C.

Municipal Finance Law’s Personal Property Frequently Asked Questions (FAQs).

Reading Each Entry

Each entry in the listing includes the name and primary location of a company, and also indicates whether the business 
has been classified as a manufacturing or research & development corporation. The “location” listing is based on the 
corporation’s own reporting to DOR, and identifies the community, state or foreign country (FC) in which the company is 
headquartered. Please note that businesses may own taxable property in one or more Massachusetts communities, but 
only the “location” of the headquarters will appear in this listing.

A corporation classified as a "manufacturing corporation” is designated by the letter "M" to the left of the corporation 
name. A corporation whose manufacturing status has been revoked during a given year is identified by the letter "R" to 
the left of the corporation name. See 830 CMR 58.2.1 explaining the application procedure for classification as a 
manufacturing corporation and Form 355Q that would be completed. A corporation classified as a "research & 
development corporation” is designated by the letter "D" to the left of the corporation name. PLEASE NOTE that this 
designation only applies if the corporation is located in a community that has accepted the local option as of January 1. 
To date, Lowell, Springfield and Worcester have notified DOR of their adoption of Chapter 59, § 5, Clause 16(3)(1) OR 
Clause 16(3)(ii).

Manufacturing, Revocation and Other Updates

The list of Corporations Subject to Taxation in Massachusetts is forwarded to assessors in or about April each year. In 
eeting this distribution objective, DOR's Filing Enforcement Bureau makes every effort to render its manufacturing 
(M), revocation (R) and research & development (D) decisions in order that all are included in the annual list. However, 
some decisions are made after publication and are retroactive to January 1 of the current year. It is DOR's policy to 
notify assessors of the subsequent decisions by letter, based on information requested and received from the applicants 
as to the locations of corporate property in the communities.

In addition, any legal entity, other than a sole proprietor, non-profit or entity that has no personal property in 
Massachusetts, that is treated as a corporation for federal income tax purposes must file the annual certification with
Department of Revenue’s MassTaxConnect ( under the Business tab at the bottom 
of the page
) to verify its status as a corporation to be included in the Corporations Book listing. Filing information for the 
Annual Certification of Entity Tax Status is located on the Businesses tab ( under 
the Online Services. Generally, if a company is not listed and it believes that it should be treated as a corporation and 
included in the Corporations Book, or if the company is listed but it believes it has been erroneously classified, an 
appeal to the Appellate Tax Board (ATB) may be filed. That appeal must be filed on or before April 30, or 30 days 
after the Corporations Book is released to local assessors, whichever is later (G.L. c. 58, § 2).

The manufacturing and revocation decisions, ATB settlements, and other revisions applicable to the current calendar 
year will be posted throughout the year until the next list is issued. Assessors should periodically check the website for 
these updates.


Boards of assessors or corporations aggrieved by classifications made by DOR under G.L. c. 59 or 63, or by action taken 
by DOR under G.L. c. 58, § 2, may, in order to preserve any rights to be correctly classified, object by applying to the ATB 
and stating the classification or action claimed. The appeal must be received by the ATB on or before April 30 of the year 
for which classification is sought, or within 30 days after the date DOR sends the corporations list to local assessors,
whichever is later.
