How a Clay County appeal works

1. August: the county mails your TRIM notice (Notice of Proposed Property Taxes) with the new assessed value.
2. 25 days: that's your window to petition the Value Adjustment Board — for 2026, on or around September 15, 2026 (your TRIM notice shows the exact date; it governs).
3. File form DR-486 with the Clay County Clerk's VAB office, with a modest filing fee (capped at $50 by statute). No lawyer required — homeowners file themselves.
4. The hearing is informal, typically 15 minutes; many counties hold them by phone, and you can even have your evidence considered without attending.
5. The evidence that matters: recent sales of comparable homes. That's exactly what our appeal packet contains, pre-assembled with the county forms filled in.
