Property taxes in Nassau County, Florida — and how to appeal yours

Like every Florida county, Nassau County assesses your home at its just (market) value each January 1, mails a TRIM notice in August, and gives you a short window — generally 25 days — to challenge the assessment before the Nassau County Value Adjustment Board. Here's what that means where you live, with hearings administered from Fernandina Beach.
