1. What is boat excise?

Chapter 60B of Massachusetts General Law imposes an excise on the privilege of registering a vessel, and its equipment, to utilize the waterways of the Commonwealth of Massachusetts. The excise is levied annually by a measured value at a rate of ten dollars per thousand of valuation unless expressly exempted. Non-registered vehicles, however, may be subject to taxation as personal property. The excise is levied by the city or town where the vessel resides and the revenues become part of the local community treasury.

Any person who owns such a vessel on July 1 shall annually, on or before August 1, make a return on oath to the assessors of the city or town where such vessel is to be moored or docked, or in the case of a vessel which has no mooring or docking space, where said vessel is principally situated, setting forth the vessel's registration or documentation number, if any; an adequate description, as well as the owner's estimate of the fair cash value of the said vessel and any engine or motor used to propel, said vessel, as of the next preceding July 1, and the place of habitual mooring or docking or other principal location of said vessel. All sums received from the excise imposed under this Chapter are paid into the treasury of the city or town and fifty % of the excise is credited to the municipal waterways improvement and maintenance fund established under the provisions of Section 5G of Chapter 40.

2. How do you know I had a Boat in Dennis?

There are several sources included in the compilation of the list of vessels and/or the equipment to receive excise tax. The main source is the list provided by the Massachusetts Environmental Police of all registered vessels in the Town of Dennis. In addition, information is received from the marinas listing all vessels that are moored or docked at the marina as well as those identified by the Harbormaster (private docks, Town-owned slips/moorings, etc.). This information contains not only the registration number but the type and size of the vessel.

3. How is the excise determined?

Excise tax is assessed annually, July 1 through June 30, (example: the FY2022 tax bills will be for the period of July 1, 2021 to June 30, 2022). For the purpose of computing the excise under this chapter the value of each vessel, and its equipment, shall be deemed to be the fair cash value as determined by the assessors of each city and town, but not in excess of the following values:

Length of Vessel	Under 4 Years Old	4 to 6 Years Old	7 or More Years Old
Under 16'	1,000	700	400
16' but less than 17.5'	1,500	1,000	800
17.5' but less than 20'	3,000	2,000	1,500
20' but less than 22.5'	5,000	3,300	2,500
22.5' but less than 25'	7,500	5,000	3,800
25' but less than 27.5'	10,500	7,000	5,300
27.5' but less than 30'	14,000	9,300	7,000
30' but less than 35'	18,500	12,300	9,300
35' but less than 40'	24,000	16,000	12,000
40' but less than 50'	31,500	21,000	15,800
50' but less than 60'	41,000	27,300	20,500
60' or over	50,000	33,000	24,800

4. How is the excise tax calculated?

Once the value of the vessel is determined, an excise at the rate of $10 per thousand of valuation is assessed. Excise tax is assessed annually, July 1 through June 30, by the assessors. If the vessel is registered after July 1, the tax will be issued in the next Fiscal Year. For example, if a vessel is registered on August 30, it will be taxable as of July 1 in the following Fiscal Year. In no event shall the excise be assessed for less than $5, nor shall abatement or refund reduce an excise to less than $5.

5. Who collects the boat excise?

Local tax collectors are responsible for collecting boat excise. Generally, tax collectors and deputy tax collectors do not accept partial payment of an Excise bill. Taxpayers should be prepared to pay the full amount due. There are no special considerations for financial hardship.

6. What happens if my payment is late?

If the bill remains outstanding more than thirty (30) days after its issuance, it will continue to accrue interest and other charges and fees for which you will be responsible. For more information, contact the Treasurer/Collector's office at 508-760-6131.

If the bill remains unpaid and outstanding more than thirty (30) days after its issue date, it will continue to accrue interest and other charges and fees for which you will be responsible. Your driver's license and/or vehicle registration will also be submitted to the Massachusetts Registry of Motor Vehicles for non-renewal action. For more information please contact of the Office of the Treasurer/Collector.

7. Can I get boat excise abatement?

If boat ownership is transferred by sale or otherwise, or if during the fiscal year, the boat owner relocates it to another state and registers the boat in the other state and has surrendered/does not renew the registration in this state, the excise shall be prorated to the amount of time that the vessel was registered. The minimum boat excise assessment is $5.

Contact the Assessor's office at 508-760-6139 for an application for abatement OR print out a form using the link below. Follow the instructions on the form and send it to the Assessor's Office located at 685 Route 134, South Dennis, MA 02660, along with the required documentation.

If you no longer own your boat, please be sure that you cancel your title and registration with the Massachusetts Environmental Police. This will help prevent future tax bills as we get the majority of our registration information from them. Click the DEP Cancellation Form link below to cancel your title and registration.

Note: It is important to remember that the bill for a vessel you no longer own should not be ignored. On unpaid excise tax bills, an owner risks incurring late fees and penalties if abatement is not granted.

8. What do I need to get an abatement?

In order to abate a Boat Excise Tax bill, the following document(s) is required along with a completed Application for Abatement and your signature on the backside of the Tax bill (top section on the back of bill) or fill out a Boat Abatement Form (PDF) and DEP Cancellation Form (PDF).

Additional Documents:

• Bill of Sale or Trade-in paperwork showing the date of sale or transfer with all pertinent boat information. Please Note: If the vessel was sold, the Massachusetts Environmental Police requires notification within 15 days of the sale.
• Copy of a paid Boat Excise bill from another town where the boat is Moored/Stored. The registered "Moored/Stored" information can be found on the Environmental Police website or via telephone at 508-771-8382 Please Note: The taxpayer is responsible for paying the town that the boat is Moored/Stored in, not the first town that sends out a bill.

9. I paid my Boat Excise Tax in another Town?

You only owe Boat Excise Tax once a year and to only one location. If you have paid your Boat Excise to another town, please provide a copy of the tax bill showing it was paid so we can abate the bill here in Dennis.

Note: It is important to remember that the bill for a vehicle you no longer own should not be ignored. On unpaid excise tax bills, an owner risks incurring late fees and penalties if an abatement is not granted.
