NJ Property Tax Assessment Lookup (MOD-IV)

Look up current New Jersey property tax assessments by PAMS PIN, municipality, address, tax block, tax lot, or property class using the State of New Jersey's public Parcel_MOD4 service.

The Actor is designed for real-estate research, tax-comparison workflows, parcel screening, GIS enrichment, and agent/API use. It reads the official NJGIN layer directly—no browser, account, or third-party data provider is required.

What it returns

Field group	Included data
Parcel identity	PAMS PIN, parcel GUID, municipality code, county, municipality, block, lot, qualifier
Assessment	Land value, improvement value, net assessed value, prior-year tax, property class and use
Property	Situs address, building and land descriptions, acreage, building class, year built, dwelling counts
Deed and sale	Deed book/page/date, sale price, sale code
Freshness	Parcel update date, publication date, retrieval timestamp, exact source query
Optional GIS	Parcel polygon in WGS84 longitude/latitude coordinates

Owner names and owner mailing addresses are not returned. The State of New Jersey redacts owner names in its hosted parcel and tax-list products under Daniel's Law; this Actor preserves that privacy boundary.

When to use it

Use this Actor when you need the current assessment record exposed by NJGIN for a known parcel, a small municipal block/lot search, a property-address search inside one municipality, or a bounded municipal/property-class list.

Do not use it for tax-bill payment status, liens, title verification, ownership discovery, market-value estimates, historical year-by-year records, or legal boundary surveys. Assessment values are not automatically equal to market value, and parcel geometry is a planning framework rather than survey data.

Input

Choose one parcel scope:

• pamsPin for an exact statewide lookup, such as 0714_702_11; or
• municipalityCode, such as 0714; or
• both county and municipality, such as ESSEX and NEWARK CITY.

Then optionally narrow with address, block, lot, qualifier, or propertyClass. maxResults defaults to 100 and is capped at 1,000. Set includeGeometry to true only when polygon coordinates are useful.

Exact block and lot

{
  "municipalityCode": "0714",
  "block": "702",
  "lot": "11",
  "maxResults": 1
}

Address inside a municipality

{
  "county": "ESSEX",
  "municipality": "NEWARK CITY",
  "address": "N 8TH ST",
  "maxResults": 25
}

Exact PAMS PIN with GIS geometry

{
  "pamsPin": "0714_702_11",
  "includeGeometry": true,
  "maxResults": 1
}

}

Every business record is written to the default dataset. OUTPUT in the default key-value store contains DATA, EMPTY, LIMIT_REACHED, REJECTED, or FAILED, the exact normalized query, record count, warnings, and source note. A valid no-match query returns an empty dataset with an explicit EMPTY summary; it never fabricates a property. When a run spending cap allows fewer records than maxResults, the Actor reduces work before querying and reports the applied limit.

API example

curl -X POST "https://api.apify.com/v2/acts/YOUR_USERNAME~nj-property-tax-assessment-lookup/runs?token=YOUR_TOKEN" \
  -H "Content-Type: application/json" \
  -d '{"municipalityCode":"0714","block":"702","lot":"11","maxResults":1}'

For production integrations, send the token in an authorization header rather than a URL and retrieve items from the run's default dataset.

Pricing

This Actor uses transparent pay-per-event pricing:

Event	Price
Actor start	$0.00005 per run
Property assessment record	$0.001 per delivered dataset item

A one-record lookup costs up to $0.00105 in event charges. A 100-record run costs up to $0.10005. A zero-result or rejected query has no result events; only the configured start event applies. maxResults is both a workload and billing cap. Platform pricing shown in Apify Console remains authoritative.

Reliability and limits

The Actor queries the public State of New Jersey ArcGIS service with bounded pagination, 30-second request timeouts, and three attempts for rate limits, transient server errors, and network failures. It deduplicates records by PAMS PIN and validates required identity fields before writing any dataset item.

The upstream service currently caps each response at 1,000 records; the Actor pages in batches and caps each run at 1,000 results. Searches are case-normalized. Address matching uses the text recorded in PROP_LOC, so abbreviations and punctuation must resemble the assessor record. For broad research or historical years, use the official bulk MOD-IV downloads or Rutgers historical database instead.

Data source and responsible use

Data comes from the NJGIN Parcels and MOD-IV program and its public NJ Tax List Search ArcGIS service. Municipal assessors and county tax boards remain the authorities for corrections and official determinations.

Use the data lawfully, minimize retention of sensitive parcel information, and independently verify decisions involving taxation, lending, insurance, title, valuation, or legal rights. This Actor does not bypass authentication, CAPTCHAs, paywalls, redactions, or access controls.

Support

When reporting a problem, include the run ID, input with secrets removed, expected parcel, and whether the official NJGIN Property Explorer shows it. Do not send private credentials or unredacted personal documents.
