Westfield NJ Property Taxes: Due Dates, Payments and Your Tax Bill
Westfield, NJ property taxes are due quarterly on February 1, May 1, August 1 and November 1. The fourth-quarter 2026 bill was due November 1, with a grace period through Tuesday, November 10. After that deadline, interest is charged back to November 1.
If you need to make a payment, start with the Town’s official property tax and sewer payment portal. If you are trying to understand a change in your bill, compare the annual figures and the installment calculations. Multiplying one quarterly payment by four can give you the wrong answer.
Information checked November 2, 2026 against the Westfield Tax Collector’s page and fourth-quarter payment notice. Use your current bill or contact the Collector for the amount due on your property.
When are Westfield property taxes due?
| Installment | Due date | Usual grace-period end |
|---|---|---|
| First quarter | February 1 | February 10 |
| Second quarter | May 1 | May 10 |
| Third quarter | August 1 | August 10 |
| Fourth quarter | November 1 | November 10 |
The grace period includes the first day of the month. If the 10th is a weekend or holiday, it extends to the next business day under the Collector’s published rules. For the current fourth-quarter bill, the stated 2026 deadline is November 10.
What happens if I pay after the grace period?
Interest is retroactive to the original due date. The Collector lists annual delinquency rates of 8% on the first $1,500 and 18% on the amount above $1,500. Ask the office for the balance through your intended payment date, rather than sending only the installment printed on an older bill.
How do I pay Westfield property taxes?
The Town’s fourth-quarter notice lists these options:
- Online: use the official Westfield payment portal. Check the property and installment before submitting, and review any fee shown for the selected method.
- In person: visit the Tax Collector at 425 East Broad Street. The current notice lists Monday–Friday, 8:30 a.m.–4:30 p.m. Office credit-card payments carry a 3% processing fee.
- By mail: address payment to Office of the Tax Collector, Town of Westfield, 425 East Broad Street, Westfield, NJ 07090. Make checks payable to Town of Westfield.
- Drop box: use the box inside the Police Station’s first set of doors or the rear Municipal Building parking-lot box beside the USPS mailbox.
After-hours drop-box payments receive next-business-day credit. Do not leave cash in a drop box; cash is accepted at the office during business hours. These timing rules matter most when you are close to the grace-period deadline.
Keep your payment confirmation until it appears on your account. If your mortgage company pays from escrow, check with the servicer before making a separate payment so you do not pay the same installment twice.
Does Westfield offer automatic property tax payments?
Yes. Westfield offers AutoPay through its online payment account system. The Town says automatic payments process on the first day of the applicable collection month. Its AutoPay enrollment instructions explain account registration, adding a billing account, choosing a payment method and enabling AutoPay.
After enrolling, confirm that the intended property is attached and that AutoPay is active. If a bill is already due, check how that installment will be handled before assuming a newly created account will pay it automatically.
How is my Westfield property tax bill calculated?
Your assessed property value and the applicable tax rate determine the basic annual calculation. The New Jersey Division of Taxation explains that municipal, county and school budgets contribute to the tax requirement. The Town collects the bill, but the full amount is not all municipal revenue.
When a rate is quoted per $100 of assessed value, the calculation is:
Assessed value ÷ 100 × tax rate = basic annual property tax.
Use the assessment and rate applicable to the same tax year. A current real-estate listing price is not a substitute for the assessment on the tax record. For a deeper explanation of the Town’s portion and capital spending, see my 2026 Westfield municipal and capital budget update.
Why can multiplying one quarterly bill by four be misleading?
Quarterly bills can reflect estimates and adjustments, so the installments need not be equal. In its 2026 third-quarter explanation, the Tax Collector said the August bill used an estimated rate, with a reconciled fourth-quarter bill to follow after certification. The published 2.371 per $100 was an estimate, not a final rate to use for every current calculation.
Here is a simplified illustration of that installment math. These are invented round numbers, not Westfield’s actual rate or a particular homeowner’s bill:
| Step | Amount |
|---|---|
| Estimated annual tax | $20,000 |
| First two installments already billed | $4,700 + $4,700 = $9,400 |
| Remaining estimated tax | $20,000 − $9,400 = $10,600 |
| Half the remainder for the third installment | $5,300 |
| Misleading shortcut: $5,300 × 4 | $21,200, which exceeds the $20,000 estimate |
The final reconciliation can change the remaining amount again. To compare years, use the full annual totals for the same property and check for assessment changes or other adjustments. That is a more useful comparison than treating one larger installment as the percentage increase for the entire year.
Should I call the Tax Collector or the Tax Assessor?
Start with the office responsible for the part of the bill you are questioning:
- Tax Collector: payments, balances, bill copies and collection questions. Call 908-789-4051 or email taxcollector@westfieldnj.gov.
- Tax Assessor: assessed value, property characteristics, ownership records and deduction applications. Call 908-789-4055. The Assessor’s page links to property maps and valuation information.
Have the property address, block and lot, tax year and the specific line you are asking about available. That makes it easier for staff to address the question without having to reconstruct which bill you mean.
What if I just bought a home or did not receive a bill?
Contact the Collector for a copy. New owners should request their bill after taking ownership; not receiving it does not remove the payment obligation. Confirm the mailing address and coordinate with your mortgage servicer if it handles escrow payments.
Where can I find New Jersey property tax relief programs?
The state’s property tax relief hub provides current information on ANCHOR, Senior Freeze and Stay NJ, including applications, eligibility and benefit status. Use the instructions for the relevant benefit year: an application filed in one calendar year may concern a prior tax year.
The Westfield Assessor’s office also provides information about deductions for eligible veterans, surviving spouses, seniors and people with disabilities. Ask which program fits your circumstances before assuming that eligibility for one program means eligibility for another.
