Relief programs
What the local record says
Senior citizen tax relief
2026 local relief for elderly/disabled owners: age 65+ or permanently disabled, gross income no more than $55,000, and capital assets no more than $125,000 excluding the dwelling and five acres; annual filing/recertification January 1–March 1.
Valuation cap or growth limit
Virginia requires 100% fair-market-value assessment; no general annual valuation cap verified. The 2026 county tax rate varies by district; a 2027 general reassessment is announced separately.
Appealing an assessment
Build the objection around evidence and the notice date.
01
Calendar the window
Use the valuation notice and the county’s published protest guidance to determine the last day to file. Do not assume the payment deadline controls the appeal.
02
Assemble support
Gather comparable sales, photographs, repair records, appraisal evidence, property characteristics, and any documentation that explains why the assessed value is incorrect.
03
File and preserve proof
Submit through the official channel, save the confirmation, and attend the board or review hearing if one is scheduled. An appraiser or attorney can help evaluate evidence when the value or stakes are substantial.
The verified protest guidance for this county is: If the language is not a specific calendar date, contact the office promptly for the current notice and board-review schedule.
