Many users search “Boston Tax Collector” because that is the simple phrase people remember. The official Boston.gov pages use Tax Collection and Collector-Treasurer language. This page uses the search term “City of Boston Tax Collector” while pointing you to the official Boston.gov payment and support resources.
The most important thing is to route your problem correctly. A payment issue is different from a value issue. A copy of a tax bill is different from a prior-year collection problem. A motor vehicle excise warrant is different from a real estate tax lien. Calling the right office first saves a lot of time.
Use Tax Collection for payments
Real estate tax payments, personal property payments, delinquent taxes, municipal lien certificates, tax takings, tax title redemptions and payment research start with Tax Collection.
Use Assessing for value and exemptions
Assessed value, residential exemption, personal exemptions, tax abatement, ward/parcel lookup and most property record questions belong with Assessing.
Use the right payment category
Boston’s payment portal includes real estate tax, personal property tax, motor vehicle excise, boat excise and other categories. Pick the right category before paying.
Boston-specific micro rule
If your question is “How do I pay or prove I paid?” start with Tax Collection. If your question is “Why is my bill amount, value or exemption wrong?” start with Assessing. If your question is “Why can’t I renew my registration?” check motor vehicle excise status and RMV consequences.
How to Pay City of Boston Real Estate Taxes Online
The fastest route is the official City of Boston real estate tax payment guide and the Pay or View Bills portal.
Before paying online, make sure you are paying the correct bill type and the correct quarter. Boston uses quarterly tax billing, so you may see more than one tax bill across the fiscal year. A payment for the wrong quarter, wrong bill type or wrong property can slow down account correction.
Open the official Boston real estate tax guide
Start with the official How to pay your real estate taxes page. It explains online, phone, mail and in-person options.
Use Pay or View Bills for the correct tax type
Use the official Pay or View Bills portal. Choose real estate tax only if you are paying a property tax bill, not motor vehicle excise or a different City bill.
Confirm bill number, ward and parcel
Keep the bill nearby. Boston says phone payments require the bill number next to the ward and parcel numbers, and if the bill number is less than six digits, you add leading zeros for the phone system.
Choose ACH or card carefully
Electronic check/ACH payments are listed as no service fee. Online debit or credit card payments carry a non-refundable processor fee, so compare the total before submitting a large payment.
Save your receipt and check posting
Save the confirmation number, tax year, quarter, bill number, amount and payment date. If you later dispute a missing payment, Boston may ask for canceled checks or original receipts.
Do not wait until 11 p.m. on a due date
Boston’s real estate tax guide says the online service is closed daily from 11 p.m. to 12 a.m. This is a small detail that matters if you wait until the last night of a quarterly due date.
City of Boston Tax Payment Options: Online, Phone, Mail and City Hall
Boston real estate taxes can be paid online, by phone, by mail or in person at City Hall.
Online
Pay by checking account, credit card or debit card through the official portal. ACH/e-check is listed with no service fee for real estate taxes.
Phone
Boston lists an automated phone payment line: 855-731-9898. The system is available 24 hours a day, seven days a week.
Mail check or money order payable to the City of Boston with the bottom part of the bill to: City of Boston, Box 55808, Boston, MA 02205.
In person
For in-person payment, Boston’s guide lists City Hall Mezzanine level payment windows M-10, M-11 and M-12. Bring the bill and accepted payment method.
Payment research
For payment disputes or research, Boston lists Mezzanine Level, Window M-31. Bring proof such as receipts, canceled checks or money order documentation.

City of Boston Tax Collection Office Hours, Address and Phone Numbers
The official Tax Collection contact page lists 1 City Hall Square, Window M-30, Boston, MA 02201-2004, phone 617-635-4131, and office hours Monday-Friday, 9 a.m. to 5 p.m.

City Hall visit reminder
Boston City Hall has different entrances and department windows. For a standard payment, check the real estate tax payment guide. For a dispute or missing payment, use the problem-bill guidance and bring proof. For value or exemption questions, go to Assessing instead of Tax Collection.
City of Boston Tax Payment Fees: ACH, Online Card and In-Person Card
The tax amount may be the same, but your payment method can change the total because card payments carry processor fees.
ACH / electronic check
Boston’s real estate tax guide lists electronic check/ACH payments as not subject to a service fee. This is usually the lowest-cost official payment method.
Online debit or credit card
Boston’s guide lists a non-refundable service fee of 2.75% of the total payment amount, with a $1.00 minimum, for online debit or credit card payments.
In-person card payment
Boston’s guide lists a 2.5% in-person card service fee with a $1 minimum. PIN-required debit cards cannot be used for the fee payment method described by the City.
Practical example: a card fee on a large Boston property tax bill can be significant. Before paying, compare ACH/e-check against card convenience. If you need a same-day receipt, check the final official checkout screen and City Hall payment rules.
Boston Real Estate Tax Due Dates and Quarterly Billing Calendar
Boston operates on a fiscal year from July 1 through June 30 and uses a quarterly real estate tax billing system.
Quarter 1
First-quarter preliminary bill is issued July 1 and generally due August 1, or the first business day after if the date falls on a weekend.
Quarter 2
Second-quarter preliminary bill is issued October 1 and generally due November 1, or the first business day after when applicable.
Quarter 3
Third-quarter actual tax bill is issued in late December/January and generally due February 1. Abatement deadline is tied to this period.
Quarter 4
Fourth-quarter bill is issued April 1 and generally due May 1. Unsettled accounts by fiscal year end can move toward lien risk.
Taxes stay with the property
Boston’s real estate tax guide explains that assessed taxes on real estate stay with the property, not simply the name printed on the bill. If you own the property, make sure the taxes are paid even if the bill still shows a prior owner or the mail went to an old address.
New-owner warning
If you bought a Boston condo, multifamily, parking space or commercial property, review your closing statement carefully. A tax proration at closing is not always the same as the City having already received your quarterly tax payment.
Late Boston Real Estate Tax Payments: Demand Notice, Interest, Warrant and Tax Lien
If Boston real estate taxes are not paid within 30 days of the date the City issued the tax, the Collector-Treasurer sends a demand notice, adds a demand charge, and interest accrues.
Demand notice after missed payment
Boston’s problem-bill guidance lists a $5 demand charge and 14% annual interest from the day after the bill was due until it is paid.
Warrant notice if demand is not answered
If the demand is not answered within 14 days, Boston says the Collector-Treasurer sends a warrant notice and adds an additional warrant charge.
Tax lien risk by fiscal year end
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
A late Boston real estate tax bill can move from a simple overdue balance into demand, warrant and lien steps. If you see a late notice, call Tax Collection and ask for the current total before sending payment.
Boston Motor Vehicle and Boat Excise Tax: Why It Is Not the Same as Real Estate Tax
If you register a car or own a boat in Boston, you may owe annual excise tax, and unpaid excise can affect license or registration renewal.
Excise tax is one of the easiest categories to confuse with property tax. The payment portal may include both, but the legal consequences and office routing are different. Boston’s motor vehicle and boat tax page explains that filing an abatement application does not excuse payment of the excise bill.
30-day demand rule
If payment is not made within 30 days of issuance, the Collector-Treasurer may send a demand for the excise plus a demand charge.
12% interest
Unpaid excise bills accrue interest at 12% from the day after the due date until paid.
RMV consequence
If the warrant process remains unpaid, Boston says you may not be able to renew your license or registration until the account is settled.
City of Boston Tax Collection vs Assessing: Which Office Do You Need?
Tax Collection handles payment and collection. Assessing handles value, exemptions, abatements, property records and many tax bill-copy questions.
Use Tax Collection for
- Current and delinquent tax payments
- Prior fiscal year payment questions
- Municipal lien certificates
- Tax takings and tax title redemptions
- Missing payment research and receipts
Use Assessing for
- Assessed value questions
- Residential exemption
- Personal exemptions
- Real estate tax abatement
- Ward and parcel lookup or bill copy help
Personal property tax for Boston businesses
Boston’s personal property tax page says business owners may need to file State Tax Form 2/Form of List by March 1. The Personal Property contact is listed as 617-635-1165 and personalproperty@boston.gov. This is an Assessing-side issue, not a general Tax Collection payment-window issue.
Boston Residential Exemption, Personal Exemptions and Tax Abatement Deadlines
If your Boston tax bill looks too high because of value or exemption issues, the Tax Collector is usually not the office that fixes the bill amount.
Residential exemption
Boston’s residential exemption page for FY2026 listed an April 1, 2026 filing deadline for the current fiscal year. Always verify the current fiscal year deadline on Boston.gov.
Personal exemptions
Elderly, blind, surviving spouse, minor child of deceased parent, veteran, National Guard and hardship exemptions have their own eligibility rules and deadline language.
Abatement
Real estate tax abatement is an Assessing process. Filing an application does not automatically mean you can ignore payment deadlines.
Do not postpone payment without official guidance
Boston’s exemption guidance warns that filing a personal exemption application does not mean you can postpone paying taxes. When in doubt, ask Assessing and Tax Collection how to protect your account while a request is pending.
What This Boston Tax Collector Refresh Adds Beyond a Basic Directory Page
A basic page gives one phone number. A useful Boston tax page helps the user choose the right payment method, quarter, office window and department.
Quarter-first guidance
Boston bills quarterly, so the guide explains which due dates matter and why a former-owner name does not remove the property owner’s responsibility.
Fee-aware payment help
ACH, online card and in-person card options are separated so users can avoid unnecessary card fees on large tax bills.
Office window clarity
The guide separates Window M-30 contact, M-10/11/12 payment windows, M-31 research and M-5 bill-copy help.
Excise tax warning
Motor vehicle excise can block registration renewal if unpaid. That is not the same user path as real estate tax payment.
Late-tax reality
Demand charges, warrant steps, 14% real estate interest and lien risk are explained plainly so users act before the issue worsens.
Assessing vs Collection
The page protects users from calling the payment office for value, exemption or abatement issues that belong with Assessing.

City of Boston Tax Collector FAQ: Payments, Hours, Due Dates, Excise Tax and Late Fees
These answers focus on real Boston taxpayer problems: paying online, choosing the right quarter, finding the correct City Hall window, avoiding card fees, and knowing when to call Assessing instead.
Best Way to Use the City of Boston Tax Collector Page
Use the City of Boston Tax Collection page when you need to pay real estate taxes, research missing payments, ask about prior fiscal year balances, get municipal lien certificate help, or understand late-payment collection steps. Use the official Pay or View Bills portal for online payments, and remember that Boston’s real estate taxes are billed quarterly.
The key user warning is simple: do not confuse payment with assessment. Tax Collection collects the tax, while Assessing handles value, exemptions, abatements and property record questions. If you are late, call early because demand notices, interest, warrant steps and liens can make a simple missed quarter more expensive.
Editorial note and official-source warning
This independent TaxCollectors.org guide helps Boston, Massachusetts property owners and taxpayers find official tax payment, office, deadline and service information. It is not the official City of Boston website, Tax Collection department, Assessing department, Massachusetts Department of Revenue, RMV, legal adviser, mortgage company or tax adviser.
Always verify current tax balances, bill numbers, fees, due dates, payment categories, office windows, mailing addresses, service closures, late-payment charges, exemption deadlines, abatement deadlines and lien procedures directly through official Boston.gov sources before acting.
