Get an email when your property tax picture changes

Free. Sign up with your address and we’ll email you when Nassau publishes a new tentative assessment for your parcel, Suffolk’s Grievance Day approaches, New York changes the STAR or senior exemption limits, or your school district holds a budget vote that affects your bill.

How this works. Nassau publishes tentative assessments each January, and we alert you within a few days of a meaningful change to your parcel. Suffolk towns publish around January to March. For STAR and senior threshold changes, we alert as soon as New York publishes them on tax.ny.gov. We don’t monitor in real time off season, and we send at most one email a month unless something time-sensitive changes.

The fine print

What we watch, and what we don’t

Signal, not spam. Most homeowners hear from us at most once a quarter unless something changes for their parcel.

What we monitor

  • New York State assessment rolls: we re-index every year and detect parcel-level changes.
  • Nassau’s tentative roll: usually published in early January.
  • tax.ny.gov annual values: Basic and Enhanced STAR income limits, senior thresholds and the tax cap, checked monthly by an automated freshness check.
  • Grievance deadlines: Nassau’s ARC deadline (usually late March) and Suffolk’s Grievance Day (third Tuesday in May).

What we don’t

  • County clerk filings in real time: deeds, mortgages and liens. Use Nassau’s Land Records Viewer or the Suffolk Clerk.
  • School board meetings: we summarize annual budget votes, not meeting minutes.
  • Mid-cycle special-district changes (fire, library, water, sewer): these arrive in our annual rate re-index.

Privacy

We collect only your email and the parcel you watch (or your county, if you don’t pick an address). We don’t sell or share it, and every email has a one-click unsubscribe. Read the privacy policy.
