Property taxes in Old Tappan are billed at a 2025 general rate of 2.346 per $100 of assessed value, funding the borough, Bergen County, and the local schools out of a single quarterly bill.1New Jersey Division of Taxation. 2025 General Tax Rates A home assessed at $500,000 owes roughly $11,730 for the year before any deductions or state credits are applied. Payments are due February 1, May 1, August 1, and November 1, with a 10-day grace period on each.
How the Bill Is Calculated
Every parcel in the borough carries an assessed value set by the tax assessor, who is required by law to determine the full and fair market value of your property based on what it would sell for in a private sale as of October 1 of the prior year.2Justia. New Jersey Code 54-4-23 – Assessment of Real Property That date matters. A renovation finished in November won’t show up in the regular assessment until the following cycle.
The tax rate itself is produced by dividing the combined spending needs of the municipality, county, and school district by the total assessed value of all taxable property in the borough. When the overall assessed base grows faster than budgets, the rate can fall even if your own bill rises. Old Tappan’s rate was 2.202 in 2024 and 2.346 in 2025.
Deductions You Can Claim Through the Borough
Two statutory deductions come straight off your tax bill if you qualify, and you apply for them through the Old Tappan Tax Assessor’s office.
Residents who are 65 or older, or permanently and totally disabled, can claim a $250 annual deduction. You must own and live in the home, and your annual income cannot exceed $10,000. The income calculation excludes Social Security benefits, federal Railroad Retirement payments, and pensions from government programs that substitute for Social Security.3Justia. New Jersey Code 54-4-8.41 – Deduction Against Tax Assessed Against Real Property of Resident Citizen Over 65 or Permanently and Totally Disabled That exclusion is why many retirees whose only income is Social Security still meet the threshold.
Veterans who served on active duty during a qualifying period of conflict and received an honorable discharge can claim a separate $250 annual deduction with no income limit.4Justia. New Jersey Code 54-4-8.11 – Deduction From Tax Bill of Veteran Surviving spouses of eligible veterans qualify too. You can combine the veteran deduction with the senior/disabled deduction, reducing your bill by $500 if both apply.
The veteran deduction uses Form V.S.S. together with a copy of your DD-214 discharge papers.5New Jersey Department of the Treasury. Property Tax Deduction Claim by Veteran or Surviving Spouse The senior/disabled deduction has its own application. For either, you’ll need your Block and Lot number (printed on your assessment notice), proof of residency, and income documentation such as bank interest statements and pension records.
State Relief Programs
Stay NJ
Starting in 2026, Stay NJ reimburses eligible senior homeowners for 50% of their property taxes, up to a maximum benefit of $6,500. You must be 65 or older, own and live in the home for the full prior year, and have household income below $500,000.6New Jersey Division of Taxation. Stay NJ – Property Tax Relief for Senior Citizens For an Old Tappan homeowner paying $11,000 in property taxes, that works out to a $5,500 credit. Social Security disability alone does not qualify you; the age requirement is strict.
First-quarter Stay NJ payments began going out in February 2026 for the 2024 program year.6New Jersey Division of Taxation. Stay NJ – Property Tax Relief for Senior Citizens If you qualify for both Stay NJ and ANCHOR, you receive whichever benefit is larger, not both.
ANCHOR
ANCHOR provides flat rebates to homeowners and renters regardless of age. Homeowners 65 and older with income up to $150,000 receive $1,750. Homeowners with income between $150,000 and $250,000 receive $1,250. Homeowners under 65 with income up to $150,000 receive $1,500. Tenants with income up to $150,000 receive $700. For younger homeowners and renters who don’t qualify for Stay NJ, ANCHOR is the primary state benefit.
Senior Freeze
The Senior Freeze reimburses you for property tax increases above a base-year amount, effectively locking your tax level at the year you first qualified. You must be 65 or older (or receiving Social Security disability) and meet income limits in two consecutive years: $168,268 for 2024 and $172,475 for 2025.7New Jersey Division of Taxation. Senior Freeze Eligibility Requirements Those ceilings are much higher than the $10,000 limit for the borough-level senior deduction, so many homeowners who don’t qualify for the deduction can still qualify here. With Stay NJ now active, most Senior Freeze participants are expected to receive a larger benefit through Stay NJ instead.6New Jersey Division of Taxation.

Paying Your Bill
Quarterly installments are due February 1, May 1, August 1, and November 1. The borough’s 10-day grace period means a payment received by the 10th of the due month avoids any penalty. After the 10th, interest applies retroactively to the original due date.8Borough of Old Tappan. Property Taxes Due
You can mail a check to the Tax Collector at Borough Hall, use the drop box on the premises, or pay online through the borough’s payment portal. Credit and debit card payments are accepted online but carry a processor convenience fee; electronic check payments typically cost less.9Borough of Old Tappan. 1st Qtr Property Taxes Due Always put your Block and Lot number on any mailed payment so it posts to the right account. If your mortgage includes an escrow account, the lender pays the borough directly from the funds collected with your monthly mortgage payment, and you won’t receive a bill to pay yourself.
Appealing Your Assessment
If you believe your assessed value is higher than what your home would actually sell for, you can challenge it. Appeals go to the Bergen County Board of Taxation and must be filed on or before April 1, or within 45 days of the date the borough mails assessment notices, whichever is later.10Justia. New Jersey Code 54-3-21 – Appeal by Taxpayer or Taxing District If your assessed value exceeds $1,000,000, you have the option of filing directly with the New Jersey Tax Court.
You file using Form A-1, the Petition of Appeal.11New Jersey Department of the Treasury. Petition of Appeal – Form A-1 The strongest evidence is recent comparable sales: homes similar in size, age, lot, and condition that sold near your assessment date for less than your assessed value. Three to five solid comparables within a mile of your property carry more weight than a long list of loosely similar homes. A recent refinance appraisal can support your case, though the county board is not bound by a private appraiser’s opinion. If physical defects reduce your home’s value, bring repair estimates and photos.
Mid-Year Added Assessments After Improvements
Finishing a major renovation or addition after the October 1 assessment date doesn’t buy you a full tax year of grace. Under New Jersey’s Added Assessment Law, the assessor can value the completed work mid-year and issue a supplemental bill prorated for the remaining months, with the full increase then carrying into the next regular tax year. Room additions, garage conversions, new detached structures, and anything that adds livable square footage commonly trigger an added assessment. A kitchen gut-renovation with high-end finishes or a new in-ground pool can also qualify. Cosmetic work like painting or replacing carpet generally does not. Whether you pulled a permit or not, if the assessor identifies the improvement, it gets added.
If You Fall Behind
Missing the grace period triggers interest at 8% per year on the first $1,500 of the delinquency and 18% per year on anything above that, calculated from the original due date.12Justia. New Jersey Code 54-4-67 – Rate of Interest on Delinquent Taxes and Assessments If your total delinquency exceeds $10,000 by the end of the fiscal year, the borough can add a 6% year-end penalty on top of the interest.13New Jersey Division of Local Government Services. Elements of Tax Sales in New Jersey A $6,000 delinquency sitting unpaid for a year would accrue roughly $930 in interest alone.
New Jersey law requires every municipality to hold at least one tax sale per year for delinquent properties. The borough doesn’t sell your home at the sale. It sells a tax lien certificate, a claim against your property for the unpaid taxes plus interest. Investors bid by offering lower and lower interest rates, and whoever accepts the lowest rate wins the certificate.13New Jersey Division of Local Government Services. Elements of Tax Sales in New Jersey
You can redeem the certificate by paying the full delinquent amount, the interest that has accrued at the auction rate, and a redemption penalty of 2%, 4%, or 6% depending on the certificate amount. If you don’t redeem within two years, the lien holder can begin foreclosure proceedings in Superior Court, and your right to redeem continues only until the court enters judgment. In Bergen County, where property values are high, tax lien certificates are attractive to investors, so this process does move forward against homeowners who ignore it.
