Princeton Property Tax Due Dates and Grace Period
Princeton property-tax and sewer bills use four standard quarterly due dates. A standard 10-day grace period applies, although the Municipality can publish a different grace period for a particular quarter.
| Quarter | Due date | Standard grace period | What to check |
|---|---|---|---|
| 1st quarter | February 1 | 10 days | Confirm any municipal holiday or special notice. |
| 2nd quarter | May 1 | 10 days | Verify the account before paying. |
| 3rd quarter | August 1 | 10 days unless extended | Third-quarter billing can be affected by final tax-rate timing. |
| 4th quarter | November 1 | 10 days | Review any current notice before the grace period ends. |
If the 10th falls on a municipal holiday or weekend, Princeton states that the grace period extends to the next business day.

Princeton Tax Assessor contact
The Tax Assessor’s office is also at 400 Witherspoon Street. The published phone number is 609-924-1084.
Assessment appeal timing
Princeton states that a regular assessment appeal to the Mercer County Board of Taxation generally must be filed by April 1 of the tax year or within 45 days after assessment notices are mailed, whichever is later. Added or omitted assessments use a different appeal schedule, so check the municipal appeal page before filing.
Princeton and New Jersey Property Tax Relief
Property-tax relief is not handled through one program. Princeton administers certain municipal deductions and exemptions, while major benefit programs such as ANCHOR, Senior Freeze and Stay NJ are administered through the New Jersey Division of Taxation.
Princeton describes an annual $250 real-property-tax deduction for qualifying senior citizens, permanently and totally disabled residents, and certain surviving spouses who meet the applicable eligibility requirements.
New Jersey’s combined property-tax-relief system includes ANCHOR, Senior Freeze and Stay NJ. Eligibility and filing requirements vary by program and household circumstances.
For the Princeton senior/disabled deduction, the Municipality says continuing recipients must satisfy the income requirement and file the continuation form with the municipal Tax Collector by March 1.
What to Do When a Princeton Tax Payment or Bill Looks Wrong
Keep your confirmation or check information and contact Tax Collection. Payments made close to a deadline should be verified before assuming the account is clear.
Princeton requires separate online transactions for tax and sewer. Check both account sections and confirm which transaction was submitted.
Contact the Tax Assessor rather than the payment office. Paying a bill and challenging an assessment are separate processes.
Check the municipal account and contact your mortgage servicer if the expected escrow payment is missing. Do not assume an escrow arrangement guarantees the municipal account has been credited.
Princeton specifically advises taxpayers enrolled in automatic payment to unenroll when selling the property so future withdrawals are not made after ownership changes.
Call the Tax Collector because interest can continue to accrue. An amount copied from an older bill may no longer be sufficient.
