How to Appeal Your Property Tax in Mississippi: Step-by-Step Guide
Mississippi property tax appeals go through the county board of supervisors — a process that’s more accessible and less bureaucratic than in many states, but one that requires preparation and documentation to succeed. Property taxes in Mississippi are already low (0.81% effective rate statewide), but an inflated assessment can still cost homeowners hundreds of extra dollars per year. Since Mississippi reassesses property on a rolling cycle — every four years in most counties — catching an error or challenging an unreasonable valuation when the new assessment arrives can lock in savings for the next four years.
The key to a successful appeal is evidence: comparable sales data, a professional appraisal, or documentation showing that the assessor’s records contain factual errors about your property. Mississippi’s appeal process favors homeowners who show up prepared. Use our property tax calculator to estimate what your taxes should be and whether your assessment appears inflated.
How Mississippi Property Tax Assessment Works
Understanding the assessment system is essential before filing an appeal:
| Component | How It Works |
|---|---|
| True Value | Assessor’s estimate of fair market value |
| Assessment Ratio (homestead) | 10% of true value for owner-occupied homes |
| Assessment Ratio (non-homestead) | 15% of true value for non-owner-occupied |
| Assessed Value | True value × assessment ratio |
| Millage Rate | Set by county, city, school district (varies by location) |
| Tax Bill | Assessed value × millage rate ÷ 1,000 |
| Homestead Exemption | First $7,500 of assessed value exempt from ad valorem taxes |
Example: A home with a true value of $200,000 has an assessed value of $20,000 (10% assessment ratio). If the combined millage rate is 120 mills, the tax before homestead exemption would be $2,400. After subtracting the $7,500 homestead exemption, the taxable assessed value drops to $12,500, and the tax bill becomes $1,500.
The most common grounds for appeal are:
- The “true value” is higher than actual market value
- The property record contains errors (wrong square footage, lot size, number of bathrooms, etc.)
- Comparable properties are assessed at lower values per square foot
- The property has condition issues not reflected in the assessment (foundation damage, deferred maintenance, etc.)
Step 1: Review Your Assessment Notice
Mississippi counties mail assessment notices annually, typically in the spring. The notice shows your property’s true value, assessment ratio, assessed value, and the resulting tax estimate. Review every detail:
- Square footage: Is it accurate? Overstatement is the most common factual error.
- Lot size: Verify against your deed or survey.
- Number of bedrooms/bathrooms: Errors add phantom value.
- Year built: Older homes should have more depreciation.
- Construction type: Brick versus frame affects assessment.
- Special features: Does the record show a pool, garage, or addition that doesn’t exist (or was removed)?
Visit your county assessor’s office or website to view the full property card. Many Mississippi counties now offer online property record access where you can see the assessor’s data for your property and compare it to neighbors.
Step 2: Gather Evidence
Strong appeals are built on evidence, not opinions. Assemble one or more of these:
Comparable Sales
Find 3 to 5 recent sales (within 12 months) of similar homes within 1 mile of your property. The sales should be comparable in size, age, condition, and location. If these comps sold for less than your assessed true value, you have a strong argument. Pull sales data from your county’s tax records, Zillow, Realtor.com, or ask a real estate agent for MLS data.
Professional Appraisal
A licensed appraisal ($350 to $500) provides an independent market value opinion from a certified professional. Appraisals carry significant weight with the board of supervisors because they follow established methodology. If the appraisal comes in lower than the assessment, the difference speaks for itself.
Property Condition Documentation
If your home has condition issues — foundation cracks, roof damage, outdated systems, flood damage history — document them with photos and repair estimates. The assessor may not be aware of these conditions, which reduce market value below the assessment.
Error Documentation
If the property record contains factual errors (wrong square footage, incorrect feature list), bring documentation proving the correct information: a survey, floor plans, building permits, or a letter from a contractor.
Step 3: File the Appeal
Mississippi’s appeal process has two levels:
Level 1: County Board of Supervisors
The board of supervisors sits as the Board of Tax Appeals during a specified period each year — typically in August or September. You must file a written appeal with the county clerk before the deadline, which varies by county but is generally 15 to 30 days after the assessment rolls are posted.
The appeal should include:
- Your name, property address, and parcel number
- A clear statement of what you’re contesting (the true value, a factual error, or both)
- Your evidence (comps, appraisal, photos, or error documentation)
- The value you believe is correct and your basis for that conclusion
You’ll be scheduled for a hearing before the board, typically lasting 10 to 20 minutes. Present your evidence clearly and concisely. The board members are elected officials, not appraisers, so explain your case in plain language. Many counties schedule all appeals during a single week, so arrive prepared and on time.
Level 2: Mississippi Tax Commission
If the board of supervisors denies your appeal, you can escalate to the Mississippi State Tax Commission within 10 days of the board’s decision. The STC provides an independent review and can adjust your assessment. This process takes longer (60 to 90 days) but provides a more formal evaluation. Few homeowners reach this level — most successful appeals are resolved at the board of supervisors stage.
Step 4: Timeline and Deadlines
| Event | Typical Timing |
|---|---|
| Assessment notices mailed | April–June (varies by county) |
| Appeal filing deadline | 15–30 days after notices |
| Board of Supervisors hearings | August–September |
| Board decision issued | Within 30 days of hearing |
| State Tax Commission appeal deadline | 10 days after board decision |
| STC review period | 60–90 days |
| Revised tax bill (if successful) | October–November |
Missing the filing deadline forfeits your appeal right for that assessment cycle. Since reassessment occurs every four years, a missed deadline means living with an inflated assessment for up to four years. Mark the deadline on your calendar as soon as you receive your assessment notice.
Common Grounds for Successful Appeals
| Ground | Success Rate | Evidence Needed |
|---|---|---|
| Factual error (sq ft, features) | Very high | Survey, floor plans, photos |
| Comparable sales below assessment | High | 3–5 recent comparable sales |
| Professional appraisal below assessment | High | Licensed appraisal report |
| Property condition issues | Moderate | Photos, repair estimates |
| Neighborhood decline | Moderate | Area sales data, vacancy rates |
| “It’s just too high” (no evidence) | Very low | N/A (avoid this approach) |

Frequently Asked Questions
How often are Mississippi properties reassessed?
Mississippi law requires counties to reassess all property at least once every four years. The specific reassessment year varies by county — check with your county assessor’s office for the schedule. Between reassessment years, values generally remain stable unless you make improvements (additions, renovations) that trigger an interim adjustment. Use our renovation ROI calculator for detailed numbers. This four-year cycle means a successful appeal can save you money for four consecutive years until the next reassessment.
What is the homestead exemption and how do I get it?
Mississippi’s homestead exemption removes the first $7,500 of assessed value from all ad valorem taxes on owner-occupied primary residences. At a typical millage rate of 120 mills, this saves approximately $900 per year. To claim it, visit your county assessor’s office within the first year of ownership with proof of ownership and primary residence (driver’s license showing the property address). You only need to apply once — the exemption remains in effect as long as you own and occupy the home. Learn more in our home buying guide.
Do I need a lawyer to appeal my property tax?
No. Mississippi’s board of supervisors appeal process is designed for homeowners to handle themselves. The hearing is informal, and you present your own evidence directly to the board. Attorneys are allowed but rarely necessary for residential appeals. A well-organized packet of comparable sales, photos, and a clear written summary is more effective than legal representation in most cases. If you escalate to the State Tax Commission, the process is more formal but still manageable without an attorney for straightforward residential cases.
What happens if my appeal is denied?
If the board of supervisors denies your appeal, you have 10 days to file a further appeal with the Mississippi State Tax Commission. The STC provides an independent review and can reduce your assessment even if the local board refused. If the STC also denies the appeal, you can take the case to circuit court — but this is rarely worth the legal costs for residential properties. Most homeowners who present solid evidence succeed at the board of supervisors level. If you’re denied, ask the board for specific reasons and address those deficiencies in any future appeal.
Can I appeal if my property value went up but my taxes didn’t change much?
Yes, you can appeal the assessed value regardless of the tax bill amount. However, consider whether the appeal is worth your time. If the assessment increased by $10,000 in true value, your tax increase (at 10% assessment ratio and 120 mills) would be about $120 per year. The cost of a professional appraisal ($350 to $500) would take 3 to 4 years to recoup. Focus your energy on larger discrepancies — if your home is assessed $30,000 or more above market value, the annual savings justify the effort. Use our property tax calculator to quantify the potential savings.
County-Specific Appeal Tips
Hinds County (Jackson)
Hinds County has the highest millage rates in the state (158 mills), making over-assessment particularly costly. Jackson’s uneven real estate market — where neighboring blocks can vary by 50% in value — creates frequent assessment inaccuracies. Properties in areas affected by the 2022 water crisis or in neighborhoods with declining values may be assessed above current market conditions. Bring recent comparable sales data from the specific neighborhood, not metro-wide averages, to your hearing. The Hinds County assessor’s office provides online access to property records, making comparable research easier. Use our home value estimator for a starting point on current values.
Harrison County (Gulf Coast)
Gulf Coast assessments can be complicated by the wide variation in values between coastal and inland properties. A home worth $250,000 south of I-10 may have an inland neighbor assessed at $180,000 just a mile north. Insurance costs also depress effective market values on the coast — a home that costs $5,000 per year in combined insurance is worth less than an identical home inland with $2,000 in insurance costs. This economic reality should be factored into your appeal if your coastal property is assessed comparably to lower-cost-to-own inland properties.
DeSoto County (Southaven)
DeSoto County’s rapid appreciation (4.5% to 5% annually) means assessments during the four-year cycle may actually lag behind market values. Appeals in DeSoto County are less common because assessments tend to be accurate or even below market. However, specific properties with condition issues, drainage problems, or unfavorable lot locations may still warrant appeals. Compare your assessment to recent comparable sales using our mortgage calculator to understand how the assessment affects your monthly payment, and check our closing cost calculator for a full picture of ownership costs.
Professional Help with Appeals
While most Mississippi property tax appeals don’t require professional help, two types of professionals can assist with complex cases:
- Licensed appraisers: A professional appraisal ($350 to $500) provides an independent, credentialed opinion of market value that carries significant weight with the board of supervisors. For properties valued over $200,000 or with unique characteristics, the appraisal cost is usually justified by potential savings.
- Property tax consultants: Some firms specialize in Mississippi property tax appeals, working on a contingency basis (they take 25% to 40% of the first year’s savings). This makes sense for commercial properties or high-value residential properties where potential savings are large enough to justify the fee.
For most residential properties under $300,000, a well-prepared homeowner can handle the appeal effectively without professional assistance. The board of supervisors hearing is informal, and presenting 3 to 5 comparable sales with a clear written summary typically produces results.
