Long Island's North Shore (Manhasset, Port Washington, Cold Spring Harbor, Huntington) pays a higher absolute tax bill on average — $13,799/yr vs. $10,788/yr South Shore. But the South Shore has the higher effective rate (2.05% vs. 1.83%) because its housing stock is more affordable. Same dollar of home value pays more tax on the South Shore.
| North Shore | South Shore | |
|---|---|---|
| Median annual property tax bill | $13,799/yr | $10,788/yr |
| Median single-family home value | $724,111 | $549,949 |
| Median effective property tax rate | 1.83% | 2.05% |
| Districts included (sample) | 28 | 56 |
Ask anyone on Long Island and they'll tell you the North Shore is "more expensive." That's true for absolute dollar bills — $13,799/yr vs. $10,788/yr is a real ~$3k/yr gap. But the gap comes entirely from home values. The median North Shore home is $724,111; the median South Shore home is $549,949. Multiply by similar effective rates and you get most of the dollar difference automatically.
What surprises people: the South Shore actually has the higher effective rate (2.05% vs. 1.83%). At identical home values, you pay more tax on the South Shore.
Three structural drivers:
Depends what you're optimizing for:
Some, not all. The very top tax-bill districts (Jericho, Roslyn, Garden City, Manhasset, Cold Spring Harbor) cluster on the North Shore. But Lawrence and Hewlett-Woodmere (South Shore) also rank high in absolute dollar terms. See the full top-list.
Both, technically. The East End forks into the North Fork (Southold, Mattituck, Greenport) and South Fork (Hamptons: Southampton, East Hampton, Montauk). For this comparison we grouped the East End North Fork with North Shore districts and East End South Fork with South Shore. The East End's tax patterns are different from the rest of LI — see low effective rates for the East End story.
It's informal. Generally the line runs along the Long Island Expressway (I-495) and the Northern State Parkway in Nassau, then along the LIE in Suffolk. Districts north of that line are "North Shore," south are "South Shore." The midline towns (Plainview, Syosset, Smithtown) often get classified either way; we classified them as North Shore for this analysis.
Suffolk South Shore (Babylon, Islip, Brookhaven southern sections) consistently shows more grievance wins because Suffolk's sporadic reassessments mean many South Shore Suffolk assessments are stale. Nassau is similar on both shores — the annual reassessment cycle keeps assessments closer to current market on both sides.
