How to Pay City of Boston Real Estate Taxes Online
The safest path is Boston.gov first, payment portal second. That helps you avoid the wrong bill type, wrong quarter, wrong parcel or unofficial payment page.
Open the official Boston real estate tax guide
Start from Boston.gov’s official real estate tax payment guide. It explains online, phone, mail and City Hall options.
Open Boston.gov real estate tax guideChoose the correct bill type
Boston’s payment portal can include real estate tax, personal property tax, motor vehicle excise, boat excise and other City bills. Pick the correct category before paying.
Match bill number, ward and parcel
Keep your bill nearby. For phone payments, Boston says the bill number appears next to ward and parcel numbers, and short bill numbers may need leading zeros.
Compare ACH and card fees
ACH/e-check is listed with no service fee. Online debit or credit card payments carry a non-refundable processor fee.
Save proof immediately
Keep confirmation number, tax year, quarter, bill number, amount and payment date. If a demand notice appears later, you may need receipts or canceled check copies.
Do not wait until 11 p.m. on a due date
Boston’s official real estate tax guide says the online service is closed daily from 11 p.m. to 12 a.m. This matters if you wait until the last night of a quarterly deadline.

Boston Real Estate Tax Due Dates and Quarterly Billing Calendar
Boston operates on a fiscal year from July 1 through June 30 and uses quarterly real estate tax billing.
| Quarter | Bill issued | Due date | Practical reminder |
|---|---|---|---|
| 1st Quarter | July 1 | August 1 | Preliminary bill based on prior fiscal year tax pattern. |
| 2nd Quarter | October 1 | November 1 | Check escrow or recent-sale responsibility before paying late. |
| 3rd Quarter | January 1 / late Dec-Jan | February 1 | Actual tax bill; abatement deadlines are tied to this period. |
| 4th Quarter | April 1 | May 1 | Unsettled accounts by June 30 can move toward lien risk. |
New-owner warning
Boston explains that assessed real estate taxes stay with the property, not simply the name on the bill. If you own the property, make sure taxes are paid even if the printed bill still shows a prior owner.
Late Boston Real Estate Tax Payments: Demand Notice, Interest, Warrant and Tax Lien
A late Boston tax bill can move from a simple overdue balance into demand, warrant and lien steps. Ask for the current total before sending a late payment.
Demand notice after missed payment
If payment is not made within 30 days of the tax issue date, Boston says the Collector-Treasurer sends a demand notice. The demand charge is $5.
14% annual interest
Boston adds interest from the day after the bill was due until it is paid off, at an annual rate of 14%.
Warrant charge if demand is ignored
If demand is not answered within 14 days, Boston says a warrant notice is sent and an additional $12 warrant charge is added.
Tax lien risk by June 30
If the account is still unsettled by June 30 of the fiscal year, Boston says a tax lien may be placed on the property and recorded at the Suffolk County Registry of Deeds.
Do not ignore a late notice
If you received a demand or warrant notice but already paid, gather the front and back of canceled checks, original receipts or money order proof. Boston says payment disputes require written request and proof.
Boston Motor Vehicle and Boat Excise Tax: Why It Is Not the Same as Real Estate Tax
If you register a car in Boston or own a boat in the City, you may owe annual excise tax. Do not confuse excise with real estate tax.
Due within 30 days
Boston’s excise guide says the bill must be paid within 30 days of the date issued.
$25 per $1,000 value
Boston explains that the tax is based on $25 per thousand dollars of the vehicle’s value.
RMV consequence
Unpaid warrant-stage excise can affect license or registration renewal until settled.
Motor vehicle excise mail payments use a different Boston box than real estate tax: City of Boston, P.O. Box 55809, Boston, MA 02205. Do not mix real estate tax mail and excise tax mail without checking the official bill.

The fastest way to fix a Boston tax problem is to separate payment proof, bill-copy requests, ownership timing, value disputes and excise consequences.
Paid but got a demand notice
Make a written request and provide proof such as canceled checks, original receipts or money order documents. Use Window M-31 for research.
Need a copy of the bill
Call TRAC at 617-635-4287 or use the Assessing contact route. Have ward and parcel ready.
Tax bill shows prior owner
Boston says the name on the bill is the property owner on January 1 before the fiscal year starts. The tax still stays with the property.
Closing or escrow confusion
Do not assume a closing proration means the City has received payment. Check the account and ask the lender/title company for proof.
Mailing address is wrong
Boston says address-change help is available, and questions can be directed to 617-635-3783.
Excise blocks renewal
Confirm whether the issue is a motor vehicle excise warrant, not a real estate tax balance.
Proof-of-payment checklist
- Confirmation number or receipt.
- Bill number, ward and parcel.
- Tax year and quarter.
- Front and back of canceled check if requested.
- Original money order proof, not only the non-negotiable copy.
- List of all affected properties if one payment covered multiple parcels.
