Mahwah property tax due dates and grace period
Property taxes are billed quarterly in New Jersey. Mahwah lists the regular installment dates as February 1, May 1, August 1 and November 1.
Township tax-bill guidance says payment must be received by the 10th to avoid interest under the Township’s normal grace period. Do not assume a postmark protects the payment date. If timing is close, confirm the current grace period and any calendar adjustment with Tax Collection because municipal grace periods can be affected by weekends, holidays or a specific tax-bill notice.
What happens when a payment is late?
Mahwah states that unpaid taxes can accrue interest from the statutory quarterly due date. Its published guidance describes interest of up to 8% per year on the first $1,500 of delinquency and 18% per year on amounts above $1,500, with a possible year-end penalty of up to 6% on certain delinquencies exceeding $10,000.

What if your mortgage company pays the taxes?
Mahwah states that tax bills are mailed to both the mortgage company and the property owner. An owner whose lender escrows taxes may receive a bill marked “This Is Not a Bill. For Advice Only.”
If the mortgage has been paid off and the lender is no longer paying property taxes, do not ignore the advice copy. Township guidance says it can be used for making the property-tax payments after the mortgage is satisfied.
What to do when a Mahwah tax payment has a problem
Tax Collector versus Tax Assessor
The Tax Collector deals with billing, collection and tax-account payments. The Tax Assessor is responsible for real-property assessments and related assessment records. If your question concerns why the property has a particular assessed value, start with the Assessor rather than asking the Collector to change the valuation.
Property tax deductions and relief for Mahwah residents
Mahwah’s tax pages point residents to local deduction/exemption information and to the New Jersey Division of Taxation for statewide property-tax-relief programs. Eligibility varies by program, age, disability status, veteran status, income, residency and property circumstances.
