Residential Tax Grievance

We set the record for tax reductions

$73,000 in Nassau County
$17,000 in Suffolk County

Property tax grievance is a formal complaint, filed on your behalf, against your town’s assessed value on your property based upon comparable sales. If we can prove your home is worth less than that value, we will accept your grievance and aggressively seek to reduce your property taxes to the lowest amount, legally allowed.

Commercial Tax Grievance

We can help you save tens to hundreds of thousands in property tax refunds.

Commercial Tax Grievance (real estate tax certiorari) is the legal process that challenges the real estate tax assessment of your commercial property to reduce its assessment, resulting in lower real estate taxes. We’ll represent you throughout the entire, stringent process and aggressively seek to reduce your property taxes to the lowest amount, legally allowed.
