Mississippi Property Tax Appeal Guide
How to challenge your property tax assessment in Mississippi - deadlines, process, and a savings calculator.
What This Data Tells Us About Appeals in Mississippi
- Administrative filing in Mississippi is listed at $0, so the first barrier is evidence and timing, not a petition fee.
- This ACS extract does not store how often Mississippi assessments are reduced on appeal; comparable sales and property-record errors are the evidence the named board typically asks for.
- The typical window centers on September; confirm the current county notice date before relying on the statewide summary. Compare Utah's September window before assuming Mississippi is early or late.
Primary signal
The administrative filing is usually free
File with the County Board of Supervisors. The reported filing-fee structure is $0; later court or tribunal stages may use a different schedule.
Decision signal 2
Mississippi's process has its own procedural details
Mississippi assesses residential property at 10% of true value. The short 10-day window after roll approval makes prompt action essential.
Decision signal 3
The filing window centers on September
Within 10 days of the Board of Supervisors' approval of the assessment roll (typically August–September). Deadlines can vary by county and assessment cycle, so confirm the current date with the local assessor before relying on this guide.
Decision signal 4
This extract does not store an appeal-win rate
The ACS county medians on this site do not include how often Mississippi assessments are reduced on appeal. Recent comparable sales and documented property-record errors are the evidence boards typically ask for.
How to read this guide and disclaimer
Use the ranked signals above as a preparation order, not as a forecast. Start with the filing window and named appeal body because a strong valuation argument cannot cure a missed deadline or a filing sent to the wrong office. Then compare the assessment with recent, genuinely similar properties and document factual errors such as incorrect square footage, condition, or classification.
An estimated success rate is not part of this ACS extract. Keep copies of the assessment notice, evidence, forms, delivery confirmation, and every response from the taxing authority. If a state rule and a county instruction differ, follow the current instruction issued by the office that will hear the appeal.
This guide is for informational purposes only and is not legal or tax advice. Deadlines, filing fees, and procedures vary by county within Mississippi and can change year to year. Always verify the current rules with your local assessor's office, or a licensed attorney or tax professional, before filing. Source: Mississippi State Tax Commission.
