New York State also advises property owners to review assessment rolls carefully. Assessment rolls list information for every property within a municipality, and most towns and cities publish tentative rolls on May 1.
| Assessment Item | What It Helps You Check | Why It Matters |
|---|---|---|
| SBL | Section, block and lot identifier. | Best field for matching property lookup, tax bills and land records. |
| Property address | Physical location of the property. | Helpful for lookup, but SBL should be used to confirm accuracy. |
| Assessment notices | Tentative or current value changes and assessment-related notices. | Important for grievance, exemption and value review decisions. |
| Property sketch | Building or property sketch details where available. | Useful when reviewing property characteristics and record accuracy. |
| School district and local district clues | School, fire, police and local district information. | Important for tax bill routing and local jurisdiction research. |
Property Tax Bills, School Taxes and Receiver of Taxes
In Nassau County, tax bill lookup depends heavily on the town or city where the property is located. Town receivers often collect county, town, special district and school taxes, while cities and villages may have separate tax pages for their own local taxes.
Town of Hempstead states that its Receiver of Taxes collects taxes for Nassau County, the Town of Hempstead, special districts and school districts. Town of North Hempstead says its Receiver of Taxes resources let users look up parcels, view bills and make secure online payments. Town of Oyster Bay says its Receiver handles billing for more than 100,000 parcels and acts as a collection agency for county, town, special district and school district taxes.
