Long Island School District Tax Pressure Index

Long Island property taxes are among the highest in the United States. The largest single line item on most Suffolk tax bills is the school tax — typically 60 to 65 percent of the total. Suffolk newspapers publish annual rankings of school-district tax rates; we add the dimension nobody else publishes: which districts have the highest underlying non-payment.

Districts that combine high tax rates with elevated arrears are under compounding pressure: less of the levied tax is actually collected on time, while the budgetary need to maintain services continues. The index below ranks districts on the size of their unpaid school-tax burden and the parcel count behind it.

The pressure index

Sortable by district, town, parcel count, or unpaid school taxes. Default sort is unpaid school taxes, descending.

How to read these numbers

One caveat to keep in mind when interpreting the table: a district's absolute arrears total is heavily correlated with its size. Larger districts like Brentwood, Sachem, and Longwood will show larger totals partly because they have more parcels. Comparing arrears relative to district enrollment or parcel count produces a different ranking; the sortable parcel-count column gives readers the scale check they need.

Why this matters

For homeowners and homebuyers, the index is a leading indicator of which districts may face budget pressure in coming years — pressure that ultimately surfaces in tax-rate increases, override votes, and cuts to programs. For investors, the patterns map onto motivated-seller availability: districts with high school-tax burdens and rising arrears produce more distressed inventory.

For journalists covering Long Island education, this is the missing public dataset — official sources publish the levied amounts but not the collection shortfall. We publish both alongside our broader Suffolk Tax Arrears Report for context.

Coverage and scope

Suffolk has more than seventy school districts; this report covers the major districts by enrollment. ZIPs that span multiple districts are attributed to the primary district for that area. Districts outside current coverage are excluded rather than estimated. Updated annually. See our glossary for definitions of "relevy," "tax certiorari," and other terms used in school-tax reporting. For underlying town-level totals see the Suffolk Tax Arrears Report.
