How Much Can Property Taxes Increase in Mississippi? 2026 Complete Guide
Updated July 2026
Quick Answer
Mississippi does not cap how much your home's assessed value can rise in a year. The 10% figure you may have heard is the assessment ratio: owner-occupied homes are assessed at 10% of true value. The real limit sits on the taxing side. Under Miss. Code § 27-39-321, a county or city cannot levy ad valorem taxes producing total receipts more than 10% above what it collected in any one of the three preceding fiscal years, with new construction and previously exempt property excluded. That caps the government's total take, not your individual bill, so your own taxes can rise faster than 10% after a reappraisal while your county stays entirely within the law.
Most homeowners never challenge their assessment, usually because nobody tells them they can or shows them how. That gap is the whole reason AppealDesk exists: see what your county has your home on record at, free, and if the number looks wrong we build the case for $49.
The 10% Figure Is a Ratio, Not a Cap
A lot of Mississippi homeowners, and frankly a lot of websites, repeat the claim that assessment increases on a homestead are capped at 10% per year. That is not how the state's system works. Mississippi classifies property under its constitution, and each class is assessed at a fixed share of its true value. Class I property, meaning single-family owner-occupied homes, is assessed at 10% of true value. Class II property, meaning other real property such as rentals and second homes, is assessed at 15%.
So if your home has a true value of $300,000 and it qualifies as Class I, your assessed value is $30,000. That is the number your millage rate is applied to. If the county reappraises your home next year at $360,000, your assessed value becomes $36,000, a 20% jump, and that is entirely legal. No Mississippi statute limits how much your assessed value can rise from one year to the next. The 10% ratio determines what share of your home's value is taxable. It says nothing about how fast that value can grow.
The Real Limit: Mississippi's 10% Levy Revenue Cap
The binding restraint in Mississippi law applies to taxing jurisdictions, not to individual assessments. Miss. Code § 27-39-321 says a county or municipality may not levy ad valorem taxes that would produce total receipts more than 10% above the receipts collected in any one of the immediately preceding three fiscal years. In plain terms, the local government's total property tax haul can grow by at most 10% over its recent history.
There are carve-outs that matter. Revenue from newly constructed property, newly added property, and property that was previously exempt does not count against the limit, and neither do levies to cover the cost of reappraisal itself. That is deliberate: growth from new houses being built should not force a rate cut for everyone else. But it also means the cap is looser in practice than it sounds, because in a growing county a meaningful slice of new revenue sits outside the limit entirely.
Here is the part that surprises people. Because the cap applies to the jurisdiction's total receipts, it does nothing to protect any single homeowner. Suppose a countywide reappraisal raises values unevenly, with your neighborhood jumping 30% while older areas barely move. The county can trim its millage rate so total collections stay within the 10% revenue limit, and your bill still climbs 20% or more, because your share of the total tax base grew. The cap held. Your bill did not.
What the Cap Never Checks: Your Assessed Value
Notice what is missing from all of this. Nothing in the revenue cap, the assessment ratios, or the exemption rules ever asks whether the true value the assessor put on your home is accurate. The entire system takes the assessor's number as given and works forward from it. If that number is too high, every downstream calculation, your assessed value, your millage bill, your exemption math, inherits the error, and the levy cap will not catch it.
Caps and rate limits only control how fast your bill can grow. Nothing in them checks whether the number underneath is right. Assessors in Mississippi set values with mass-appraisal models that price thousands of homes at once, and nobody reviews yours unless you challenge it.

What Is Mississippi's Property Tax Rate in 2026?
Mississippi has no single statewide property tax rate. Your effective rate is set locally by the millage rates your county, city, and school district adopt each year, applied to your assessed value. Because Class I homes are assessed at only 10% of true value, headline millage numbers overstate what you actually pay relative to your home's market value. A home taxed at 100 mills pays 100 mills on 10% of its value, which works out to roughly 1% of true value before exemptions.
To find your actual 2026 rate, look at your most recent tax bill or ask your county tax assessor for the combined millage in your taxing district. Rates vary meaningfully from county to county and even between districts inside a single county, so any statewide average would tell you little about your own bill.
How Much Is Property Tax in Mississippi on a Typical Home?
The arithmetic runs in two steps, and you can do it on the back of an envelope. True value times the 10% Class I ratio gives assessed value. Assessed value times the total millage, divided by 1,000, gives the tax before exemptions. On a $300,000 owner-occupied home, assessed value is $30,000, and at a combined 100 mills the tax before exemptions is $3,000. On a $150,000 home, assessed value is $15,000 and the same millage produces $1,500.
Then subtract exemptions. The regular homestead exemption is a credit of up to $300 against the bill, reaching the maximum once assessed value hits $7,500, which corresponds to about $75,000 of true value. Because millage differs so much by district, plug your own combined rate into that formula rather than trusting a statewide figure. Your tax bill lists both your assessed value and the millage that produced the number.
How Millage Rates Work, and What a Millage Increase Costs You
A mill is one dollar of tax per $1,000 of assessed value. That makes millage increases easy to price out for yourself. If your county board approves a 2-mill increase in 2026, the owner of a $300,000 owner-occupied home pays an extra 2 mills on $30,000 of assessed value, which is $60 per year. The owner of a $150,000 home, assessed at $15,000, pays an extra $30. A $500,000 home, assessed at $50,000, absorbs $100.
When you see a local headline about a proposed 2-mill increase, take your assessed value from the tax bill, multiply by the number of new mills, divide by 1,000, and you have your personal dollar impact. It is almost always smaller than the debate makes it sound, which is precisely why the assessed value line, not the millage line, is usually the one worth arguing about.
The § 27-39-321 revenue cap constrains these decisions in aggregate. A board cannot stack millage increases that would push total receipts past 110% of any of the last three years' collections, setting aside revenue from new construction and previously exempt property. Within that envelope, millage adjustments are a normal part of local budgeting.
Does Mississippi Have Property Tax?
Yes. Mississippi levies ad valorem property tax at the local level on real property, with counties, municipalities, and school districts each setting millage. What softens the burden for homeowners is the combination of the low 10% assessment ratio on owner-occupied homes and the homestead exemption, which must be filed for with your county and is not applied automatically. Homeowners who are 65 or older, or 100% disabled, get a substantially larger break, covered further down.
Why Do My Property Taxes Go Up Every Year?
If your Mississippi tax bill climbs year after year, one or more of three things is happening. Your assessed value is rising, and since there is no cap on assessment increases, a reappraisal that tracks a rising market flows straight through to the bill. Your millage rate went up, because local boards adjust millage annually within the revenue cap and county, school, and municipal levies each move independently. Or an exemption changed: the homestead exemption is not automatic, and a missed filing or a change in occupancy status can quietly raise what you owe.
The year worth watching is the reappraisal year. In an ordinary year your value may barely move and your bill changes only with millage. In the year your county updates values, the increase can be large and uneven across neighborhoods, and that is exactly the year a mass-appraisal model is most likely to overshoot on an individual home. Reappraisal timing is set county by county, so ask your assessor when your county last updated values and when the next update is scheduled.
Will Property Taxes Go Down in 2026? What Changed
For one group of Mississippi homeowners, 2026 brings a real cut. In 2025 the Legislature passed HB 1255, raising the special homestead exemption for homeowners who are age 65 or older or 100% disabled. Effective January 1, 2026, those homeowners are fully exempt from ad valorem taxes on up to $12,500 of assessed value, up from the prior $7,500. Because of the 10% ratio, $12,500 of assessed value corresponds to roughly $125,000 of true value. A qualifying senior in a home worth $125,000 or less owes no ad valorem property tax at all, and seniors in more valuable homes see the first $12,500 of assessed value come off the taxable base.
For everyone else, no statewide 2026 change pushes bills down. Whether your own taxes fall depends on local millage decisions and on whether your assessed value drops, which generally happens only if the market falls or you successfully challenge the value.

Mississippi: No assessment cap. Nothing limits how fast your assessed value can climb, so the bars above are what protection looks like elsewhere.
The 10% figure often quoted for Mississippi is an assessment ratio, not a cap.
A cap limits how fast the number grows. It does not check whether the number was right to begin with.
What you can do about it
How and When to Challenge Your Assessment in Mississippi
Mississippi's objection process runs through your county Board of Supervisors, which sits as a board of equalization to hear objections to the assessment roll at its meeting on the first Monday of August (Miss. Code § 27-35-89 and § 27-35-131). The land roll, the list of every property's assessed value, is made available for public inspection in July. That July window is when you should be checking your number.
The mechanics vary by county, so confirm the details locally. Counties commonly require written objections filed by around August 1, and some ask homeowners to request a review by mid-July so the assessor's office can inspect the property before the board meets. Madison County, for example, has used a written-objection deadline near August 1. If the board rules against you, Mississippi law allows a further appeal to circuit court, but verify that filing deadline with your county or an attorney, because it is short and we have not confirmed a statewide figure.
The practical takeaway is that the window is narrow and front-loaded. By the time your tax bill arrives in the winter, the year's assessment is locked in. The time to compare your assessed value against real sales of comparable homes is July, with your objection on file before the board convenes in August.
A real AppealDesk order, Knox County, Tennessee
In May 2026, a homeowner in Knox County, Tennessee ran the check. The county had their home on record at $795,300, while recorded sales of comparable homes supported about $553,918: an over-assessment of $241,382, worth roughly $938 per year if corrected. Their packet laid out the comparable sales, the forms, and the filing steps. Nobody at the county was ever going to run that check for them.
Growth limits only help if the number they grow from is fair. If your assessment jumped after a purchase, new construction, or a revaluation, that new number is the one nobody has reviewed. Checking it is free and takes about a minute.

Frequently Asked Questions
How much can my Mississippi property taxes increase this year?
There is no fixed limit on your individual bill. Your assessed value can rise as far as the assessor's reappraisal says it should, and millage can move within the county's revenue cap. The only hard ceiling in the law applies to the jurisdiction's total collections: under Miss. Code § 27-39-321 a county or city cannot collect more than 110% of its receipts from any one of the prior three fiscal years, excluding new construction and previously exempt property. Your personal bill can outrun that figure in a reappraisal year.
Is there a 10% cap on assessment increases for a Mississippi homestead?
No. This is a common misreading. The 10% figure is the assessment ratio for Class I owner-occupied homes, meaning 10% of your home's true value becomes the taxable assessed value. It is not a limit on how much that value can increase from year to year. Mississippi has no annual assessment-increase cap on homes.
What exemptions do Mississippi homeowners get?
The regular homestead exemption is a credit of up to $300 against your tax bill, reaching the full amount at $7,500 of assessed value, roughly $75,000 of true value. Homeowners who are 65 or older or 100% disabled are fully exempt from ad valorem taxes on up to $12,500 of assessed value, roughly $125,000 of true value, effective January 1, 2026 under HB 1255. You must file for homestead exemption with your county; it is not applied automatically.
When is the deadline to challenge my property assessment in Mississippi?
Objections are heard by the Board of Supervisors sitting as a board of equalization on the first Monday of August, and the assessment roll is open for inspection in July. Many counties require written objections by around August 1, and some want review requests by mid-July. Because the exact filing requirements vary, call your county tax assessor's office in early July to confirm your county's procedure.
Can my bill go up more than 10% even though the county has a 10% cap?
Yes. The 10% limit in § 27-39-321 applies to the taxing jurisdiction's total revenue, not to any individual parcel. After a reappraisal, homes whose values rose faster than the county average pick up a larger share of the total levy, so those bills can jump well past 10% while the county's overall collections stay inside the cap. If that describes your situation, the assessment itself, not the millage, is usually the number to challenge.
