Nassau County Property Tax Part 1
You received your TRIM notice—now what?
If you own property in Nassau County, your TRIM (Truth in Millage) notice is an important document to review. Here’s what to know:
📄 The 3 columns:
• Prior-year taxes
• Current taxes based on existing budgets
• Maximum with proposed taxes
The third column often ends up closest to the final tax bill. You can also attend your local taxing authorities’ budget hearings to learn more and share your opinion about proposed tax rates.
🔎 Look at the bottom: Your notice shows your Market Value, Assessed Value, Exemptions, and Taxable Value. For homesteaded properties, assessed value is protected from annual increases of more than 3%, which can create a significant difference between your market and assessed values over time.
📅 Key dates:
January 1 – Property status, ownership & residency
March 1 – Homestead exemption deadline
August – TRIM notices
November 1 – Tax bills mailed
Disagree with the market value of your property? You can appeal with the Property Appraiser. Don't wait—address concerns between receiving your TRIM notice and mid-October.
When purchasing a home, don't assume you'll pay the seller's current tax bill. A change in ownership can reset the assessed value.
For tax-specific questions, always consult the Nassau County Property Appraiser or a qualified tax professional.
