Frequently Asked Questions
When can I file an appeal? +
Every year, you have the opportunity to challenge your property taxes in Nassau County. The deadline to file is March 1st. Don't let previous denials discourage you – persistence can pay off! Appealing your assessment is a powerful tool to potentially lower your tax bill. Don't wait - start the process today!
How is my fee calculated? +
There are two ways to pay for our services: Option A) Fixed Cost: Pay a one-time fee of $239 upfront. This fee covers our efforts, even if the initial assessment remains unchanged. All savings are yours to keep. OR Option B) Success-Based: Pay 30% of the amount we save you on your first year's property taxes after the county finalizes your bill. Let's say we successfully reduce your property taxes by $1,000. With our performance-based fee, you'd only pay $300. No reduction = no fee.
Will filing for a reduction affect my exemptions? +
Don't worry, filing a grievance won't impact your existing exemptions!
Can my taxes increase if I file a grievance? +
No. Many homeowners hesitate to file a property tax grievance because of a common misconception: that filing a grievance could lead to an increase in their taxes. Let us assure you, this is absolutely not true! Filing a grievance is a way to challenge your property's assessed value, and the only possible outcomes are a successful reduction in your taxes, or no change at all. Your taxes will never go up simply because you exercised your right to challenge the assessment.
How long is the property tax grievance process? +
While the grievance process can take time, often exceeding a year, there's a silver lining! Any reduction in your property tax will be applied retroactively to the beginning of the tax year you filed. So, even if your case isn't settled immediately, you'll still receive a refund for the overpayment you made.
