Where every property tax dollar goes
Most Commack homeowners pay $21.09 per $1,000 of full market value in core property tax (county, town and school) for the 2024–2025 roll year. Because this district spans more than one town, parcels elsewhere in it pay a different combined rate; the median bill is computed per parcel using each parcel’s own rate. Village, library and special-district levies stack on top where they apply.

|---|---|---|
| School | $16.410 | 77.8% |
| Town | $2.990 | 14.2% |
| County | $1.690 | 8% |
| Core rate | $21.09 | 100% |

Frequently asked questions
What is the average property tax bill in Commack?
The median residential bill is $14,683 per year ($1,224 a month). That is the median across 11,630 single-family parcels in the district. Individual bills vary with assessed value, location within the district, and any village or special-district levies that apply.
Why are property taxes higher in Commack?
Long Island property taxes reflect three layered budgets: the school district (typically 60–75% of the bill), the town and the county. In Commack, the school rate alone is $16.41 per $1,000 of full market value, roughly typical for Long Island. Districts spend different amounts per pupil, carry different debt, and serve different home-value bases.
How do I lower my property tax bill in Commack?
Two main paths. First, exemptions: STAR (every homeowner), Enhanced STAR (65+, income limit), senior, veterans and volunteer firefighter. Second, a tax grievance: if comparable homes nearby are assessed lower, file with your town’s Board of Assessment Review (Suffolk: third Tuesday in May; Nassau: by the March deadline). Grievance firms typically take 50% of the first year’s savings on contingency.
What’s a typical home value in Commack?
The median single-family home in Commack has a market value of $708,750 on the 2024 New York State assessment roll. The 10th to 90th percentile range is $555,556 to $978,750.
Is Commack a good school district?
School quality is subjective. For objective measures, see the New York State Education Department’s official report card for graduation rates, test scores and per-pupil spending. We don’t rate schools here; we cover property tax only.

Methodology and sources
- Parcels and assessment values: NY State Office of Real Property Tax Services (ORPTS) combined parcel file, roll year 2025. data.ny.gov
- Tax rates: NY State ORPTS county, town and school combined rate file, roll year 2024. tax.ny.gov/research/property. The state publishes final rates a year after the fact.
- Median bill: for every residential parcel we compute a projected bill as full market value × combined county, town and school rate ÷ $1,000, then take the median. This handles districts that span several towns. Village, library and special-district levies are excluded because they vary parcel by parcel.
- District name and code: NY State ORPTS school-district reference file. For official enrollment, see the NYSED report card.
