Who has to register
Anyone who rents a home, or part of one, for 31 consecutive days or less. The Department of Revenue calls you an operator, and each property needs its own Certificate of Registration.
- You rent only through an agent or a platform and never touch the money.
- You rent just a week or two each summer (you may qualify for the 14-day exemption, below).
- Your house is owned by an LLC, a trust or several family members.
- You normally rent by the month, but might ever take a booking of 31 days or less.
One property, one certificate. If you own more than one rental home, each address gets its own certificate number.
The certificate matters to your agent too. When an agency like ours collects the rent and pays the occupancy tax for you (the law calls us an intermediary), we cannot do it without your certificate number on file, and the Department of Revenue can require a listing to come down if the operator is not registered.
Have these ready before you start
- Your Social Security number, or the FEIN if the home is held by an LLC, trust or corporation.
- The exact legal name of the owner of record. If an entity owns the house, register in the entity’s name, not yours.
- The full property address, including any unit number.
- An email address you actually check. The Department of Revenue sends notices there.
- A prior Massachusetts tax due or refund amount, in case you need to verify your identity.
Path A: you already have a MassTaxConnect login
Most owners who have filed Massachusetts income or business taxes online already do. Do not create a second account.
- Log in to MassTaxConnect with your existing username and password.
- Open the More… tab.
- Select Add an Account, New Location, or New License.
- Choose the Room Occupancy Consolidated account type (for activity from July 2019 on).
- Enter each property you rent. The Department of Revenue issues a separate certificate for each address.
Path B: you don’t have a login yet
- Go to MassTaxConnect and choose Sign Up.
- Pick the option that describes the owner of the property: Create My Logon if you or your entity has filed Massachusetts taxes before; Register a Business for an LLC, trust, partnership or corporation that has not; Register an Individual for a person who has not filed or paid Massachusetts tax; or Register an Estate.
- Registering as an individual? Choose Social Security number as the ID type, select Personal Income Tax, and verify with a tax due or refund amount over $0 from one of your last three Massachusetts returns. If you can’t, call the Department of Revenue’s Trustee Tax Contact Center at (617) 887-6367, option 3 then option 2.
- With your password set, go to More…, then Add an Account, New Location, or New License, add Room Occupancy Consolidated, and enter your properties.
Only one owner per property registers as the operator. That does not let anyone else off the hook: every owner stays responsible for making sure the right tax is collected and paid.
After you register: three things to do
- Send your agent the certificate number. In MassTaxConnect, open the Room Occupancy Consolidated account, choose View Operator’s Properties, then View Certificate. Use the certificate number (it starts with a C), not the ROC account number: the certificate number is what routes your tax to the right town. Our owners can upload it straight into their Owner Hub.
- Post the certificate in the house. State law requires it. The guest binder or the inside of a closet door works.
- Keep it with your rental records. Booking sites increasingly ask for the number on the listing, and your insurer or town may ask to see it.
Renting 14 days or fewer this year?
You still have to register, but you can claim the 14-day exemption and collect no tax. Two things trip owners up:
- The exemption is claimed per property, per calendar year, and must be renewed by January 15 of the year you claim it: log in, open Room Occupancy Consolidated, go to Property List, choose Manage, then Renew and submit.
- If you go past 14 nights in the year, you owe the tax that should have been collected on those first 14 days too. Tell your agent early if you are close to the line.
Selling, or taking the home off the rental market
Cease the property in MassTaxConnect so the Department of Revenue stops expecting returns: View Operator’s Properties, then Manage, then the cease option at the bottom of the page, and enter the date. Tell your agent too, so the calendar and any deposits on hand are closed out properly.
And remember the certificate is not a one-time errand. Add a certificate when you buy another rental, cease one when you sell, and update the operator name if the house moves into a trust or LLC. A five-minute check every January prevents most problems.
Quick checklist
- Registered the property on MassTaxConnect and received a certificate number

- Posted the certificate inside the property
- Confirmed $1,000,000 of liability coverage and told your insurer the home is rented (insurance guide)
- Checked your town’s registration, inspection and night-cap rules (town rules)
- Claimed or renewed the 14-day exemption by January 15, if it applies

Questions we hear
Does registering cost anything?
No. Registration with the Department of Revenue is free. (Some towns, like West Tisbury, charge for their own separate town registration.)
Is my registration public?
Yes. The state publishes registered properties in its Public Registry of Lodging Operators.
I only rent through an agency. Do I still need to register?
Yes. The agency collects and pays the tax as your intermediary, but you, the owner, are the operator, and each property needs its own certificate.
Which number do I give my agent, the ROC number or the certificate number?
The certificate number, which starts with a C. It routes the local share of the tax to the right town.
Do I need to register if my house is in an LLC or a trust?
Yes, in the entity’s name, using the entity’s FEIN.
How long does it take to get the certificate?
The online registration usually takes about twenty minutes, and you can view the certificate in MassTaxConnect once the property is added.
