How to find the information

Start with the municipality where the parcel lies. New Jersey municipal collectors hold the local collection account, even when the bill includes county or school charges. The example below covers Trenton only. For another place in Mercer County, use the Office website link to the state’s County and Municipal Web Sites directory, then confirm the municipality’s official collector and public-records custodian. That directory cautions that some listed sites may not be official.

For City of Trenton property, use Division of Tax. The division expressly maintains collection records/reports and handles delinquent notices, annual tax sales and lists of properties for tax foreclosure. Ask which existing report matches the collection stage and years required.

For records beyond the published page, ask the responsible collector for an existing delinquent real-estate report, account/payment ledger or current lien-redemption calculation. Identify the municipality, block/lot/qualifier or tax-account ID, years, desired as-of date and preferred inspection/electronic-copy format. Ask whether tax, sewer, water and other municipal charges are separate. For a formal existing-records request, use that municipality’s records custodian/OPRA route; confirm any copying, extract or certification charges before ordering.

What to ask for

“I am looking for publicly available delinquent real-property tax records for Mercer County for [tax year]. Which office maintains these records? Is there an online search or downloadable list? If not, how can I request a copy, and what fees apply?”

Have the property address, parcel number, owner name, and tax year ready when searching for a particular property.

County-specific notes

Its Notice of Tax Sale Certificate Assignment is a different record from the full current delinquency ledger. Assessment/deduction questions have a separate Assessment Office contact. An ordinary linked payment gateway did not provide inspectable search controls in this review; contact the division for records outside the published navigation. Reviewed status concerns source/access guidance, not certified taxpayer liability. Tax-sale notices, recorded liens, assessed values and current collector balances have different coverage. No taxpayer rows, sale-list attachments or account results are reproduced.

An independent directory, not a government agency.

We help you locate records; we do not store taxpayer lists, determine delinquency, collect taxes, or sell tax liens. Confirm balances, payment status, deadlines, and fees with the responsible office. A tax-sale list is not a complete list of delinquent accounts.
