What the City of Quincy MA Tax Collector Handles
Quincy uses a Treasurer-Collector structure. The Collector side handles payment and billing tasks. The Assessor side handles value, tax-rate, exemption and abatement tasks.
Use the Treasurer-Collector when your question is about paying, proving payment, duplicate bills, paid/unpaid real estate tax information, Municipal Lien Certificates, current balances, Collector inquiries or city bill routing.
Use the Assessor when your question is about assessed value, property classification, tax rates, exemptions, real estate abatement, personal property forms, motor vehicle excise abatement or boat excise abatement.
| User question | Start with | Why this avoids delays |
|---|---|---|
| How do I pay my bill? | Treasurer-Collector / UniPay | Payment posting and payment proof belong with the Collector side. |
| Why did my assessed value change? | Assessor | The Collector cannot lower a certified value at the payment counter. |
| I sold my vehicle. Can I reduce excise? | Assessor | Excise abatement is an Assessor route, even though payment is through Collector/UniPay. |
| I need proof for closing. | Collector resources | Paid/unpaid real estate tax information or an MLC may be needed by title or closing parties. |

Do not start from a random search ad or old bookmark. Start with Quincy’s official payment center, then confirm the bill type inside the City of Quincy UniPay page.
Open the official payment route
Start with the City of Quincy Online Payment Center or the City of Quincy UniPay page. Confirm the page says City of Quincy before entering payment details.
Open official payment centerChoose the exact transaction type
UniPay lists City of Quincy categories such as Real Estate, Personal Property, Boat Excise and Water. A payment in one category does not clear a different bill type.
Open City of Quincy UniPayUse the correct bill year and bill number
For recent real estate bills, UniPay says July 1, 2025 is the first day of Fiscal Year 2026 and instructs users to enter bill year 2026 when trying to pay a recent bill.

City of Quincy Property Tax Due Dates: August, November, February and May
Quincy real estate taxes are billed quarterly. The first two bills are preliminary, and the third and fourth bills reflect the actual valuation, tax rate and final annual calculation.
| Quarter | Due date | What the bill usually means |
|---|---|---|
| 1st quarter | August 1 | Preliminary tax bill based on the prior year’s tax pattern. |
| 2nd quarter | November 1 | Second preliminary payment before the actual bill is finalized. |
| 3rd quarter | February 1 | Actual bill period showing new value, tax rate and adjusted annual calculation. |
| 4th quarter | May 1 | Final quarterly payment for the fiscal year. |
Why the January/third-quarter bill matters
The third-quarter bill often explains why a bill changed. It reflects the full and fair cash assessed value, the fiscal-year tax rate and the annual tax calculation after preliminary payments and exemptions.
Do not wait for a paper bill if you know taxes may be due
If a bill is lost, mailed to a prior owner, delayed, or missing from your records, use the official duplicate bill route or contact the Collector. Missing a paper bill does not prove the account is clear.

Quincy FY2026 Residential and Commercial Tax Rates
Tax rate information helps explain how a bill is calculated, but it does not replace the official bill balance shown by the Collector or UniPay.
| Fiscal year | Residential tax rate | Commercial tax rate |
|---|---|---|
| 2026 | $11.78 per $1,000 of assessed value | $23.53 per $1,000 of assessed value |
| 2025 | $11.53 per $1,000 of assessed value | $23.01 per $1,000 of assessed value |
| 2024 | $11.27 per $1,000 of assessed value | $22.45 per $1,000 of assessed value |
Rate is not the whole bill
Your final bill depends on assessed value, classification, exemptions, preliminary payments, abatements and any unpaid prior balance. If the amount due is the issue, use the Collector. If the assessed value or exemption is the issue, use the Assessor.
Official source: Quincy Assessor — Tax Rates.Quincy Motor Vehicle and Boat Excise Tax: Payment vs Abatement
Motor vehicle and boat excise are common Quincy pain points because payment and abatement are not the same task.
Pay current excise
Use the official payment path for the bill type. Save proof because unpaid excise can affect later records and renewals.
Open UniPayAsk for abatement
If you sold, traded, junked, moved out of state, cancelled registration or believe the excise is wrong, use the Assessor abatement route.
Open Assessor excise pageIf no bill arrived
Quincy’s Assessor guidance says vehicle owners who do not receive an excise bill should contact the Collector at 617-376-1085.
Motor vehicle excise late-payment caution
Quincy Assessor guidance says motor vehicle excise interest can accrue at 12% annually from the day after the due date if the bill is not paid within 30 days of issuance. Additional fees can also apply, and unpaid bills can eventually affect RMV renewal ability.
Boat excise warning
Boat excise penalties can include interest, collection costs and penalties. Quincy’s Assessor page explains that boat excise bills are generally sent no earlier than April 1 and no later than May 1 for FY2026, and boat owners have 60 days from issue date to pay.
Documents to gather for abatement
- Bill of sale, trade-in, junk or theft/total-loss proof.

- Out-of-state registration if you moved.
- Insurance cancellation or supporting paperwork if relevant.

- How do I pay my Quincy bill?
- Did my online payment post?
- Can I get a duplicate bill?
- Is real estate tax paid or unpaid?
- How do I request an MLC?
- Which UniPay bill type should I choose?
Assessor questions

Quincy Tax Payment Troubleshooting: Missing Bill, Wrong Year, Escrow, Late Excise or Posting Delay
This is the section that prevents real user problems. Use it before paying twice, calling the wrong office or waiting past a deadline.
What if the bill is not found?
Check bill type first. Then try bill year, bill number, taxpayer name and property address. For recent real estate bills, pay attention to the FY2026 bill-year note.
What if escrow should pay?
Check the official account status. If unpaid, ask the mortgage company for payment date, amount, check/ACH proof and tax bill details.
What if payment does not post?
Do not immediately pay twice. Save the confirmation and contact the Collector with the bill year, bill number, amount and payment method.
What if the bill increased?
If the increase is from value or rate, use the Assessor. If the question is amount due or posting, use the Collector.
What if excise is late?
Late motor vehicle excise can create interest, fees and later RMV renewal problems. Verify the balance and act quickly.
