How to Search Sullivan County Beacon Property Assessment Data
Beacon is the county’s newer tax parcel information portal. Sullivan County says it helps users locate public data about properties, including location, acreage, structures, purchase dates, taxes, maps, aerial photos and more. It replaces the longtime Image Mate Online program while remaining linked from the same property assessment data page.
Municipality
Choose the correct town/village first so names and streets do not return wrong parcels.
Name search
Use last name only first, then add first name or business words if needed.
Street search
Use a simple street number and street name; avoid punctuation and extra labels.
Aerial + tax map
Use map/aerial context after you confirm the correct parcel record.

- Write down municipality, owner name, street address, parcel ID or prior tax-map clue.
- Open the Sullivan County Property Assessment Data page.
- Continue to the Beacon property data link.
- Search by municipality, owner’s name or street address.
- Open the matching property result and confirm location, acreage and owner/address details.
- Copy parcel ID, municipality, tax-map reference, assessed value, purchase date and structure clues.

Micro step-by-step: If Beacon search fails
- Remove street suffixes like Road, Rd, Avenue, Ave, Lane, Ln or Drive.

- Try municipality + street name instead of full address.

Tax Map Gallery

|---|---|---|
| No Beacon result | Wrong municipality, street spelling, owner format or rural/vacant property issue. | Search municipality first; try owner last name only or simple street name. |
| Deed not found online | Record before April 1970, wrong party name or no book/page/instrument clue. | Call the Land Department and use party names plus document type/date range. |
| Wrong tax office | Treasurer handles delinquent County/Town taxes, not every current school/village tax bill. | Confirm the tax year and collecting office before paying. |
| Tax map prints badly | Large map file or wrong print settings. | Use “fit to printable area,” “current view,” and “current page.” |
| Credit card fee surprise | Treasurer card payments include a bank convenience fee. | Expect 2.75% fee or ask about check/money order options. |
