If you own a home on Staten Island, there's a decent chance you've had a conversation — at a backyard barbecue, at the school drop-off, at the diner on Forest Avenue — about property taxes. Specifically, about how they keep going up and what exactly the city is basing them on.
The frustration is legitimate. NYC's property tax system is notoriously opaque, and Staten Island homeowners often end up paying a disproportionate share relative to assessed market value.
How NYC Property Assessments Work
NYC assesses all properties annually. For one-to-three family homes (Class 1 properties — most common on Staten Island), the city assesses value at 6% of estimated market value. If your home is estimated at $600,000, the assessed value is roughly $36,000. At the 2025 Class 1 tax rate of 20.09%, that's ~$7,232/year before exemptions.
One quirk: Class 1 assessed values can only increase by 6% per year or 20% over five years. That cap protected longtime homeowners in rising neighborhoods — but newer buyers sometimes find their assessments already near market reality while longtime owners still benefit from capped values.
What Actually Triggers a Reassessment
Sale activity — when your home sells, DOF updates its estimate based on the sale price.
Comparable sales — DOF's mass appraisal model adjusts values based on recent sales of similar nearby properties. If your block has seen rising prices, your assessed value can move even if your home didn't sell.
Permit activity — adding a bedroom, finishing a basement, building a garage can cause your assessed value to rise.
Annual review cycle — the Tentative Assessment Roll publishes in January. You have until March 1 to file a challenge.

Small Claims Assessment Review (SCAR): If administrative review fails, file a SCAR petition in Staten Island Supreme Court (~$30). Accessible to homeowners without lawyers.
Tax grievance firms work on contingency — they take ~50% of any reduction secured. No reduction, no fee.
Exemptions That Can Reduce Your Bill Right Now
STAR: Available to all primary homeowners. Enhanced STAR for seniors 65+ with income under $98,700.
Veterans exemption: Available to eligible veterans and surviving spouses.
Senior Citizen Homeowner Exemption (SCHE): Age 65+, combined income under $58,399. Can reduce assessed value by 5-50%.
Disability Homeowner Exemption (DHE): Similar to SCHE for qualifying disabled homeowners.
These require an application, not a fight. Many eligible Staten Island homeowners leave money on the table by not applying.
The Bottom Line
Know when your Tentative Assessment Roll drops (January). Review it immediately. Gather comparable sales data. File before March 1 if something looks off. Apply for every exemption you qualify for — savings compound over years.
Property taxes on Staten Island run $7,000–$12,000+ annually for median-value homes. A successful challenge can knock off $500–$1,500/year.
