TL;DR
The Madison County (Alabama) Revenue Commissioner sets assessed values on all real and personal property in the county, including Huntsville. Homes are assessed at 10% of appraised value. You get 30 days from your assessment notice to file a written appeal with the County Board of Equalization. Homestead, senior, and veteran exemptions can cut your taxable value before you ever file an appeal.
What does the Madison County tax assessor actually do?
In Alabama, the office people call the "tax assessor" is really the Revenue Commissioner, and one office does everything: appraising property, applying exemptions, and collecting the tax. Madison County's Revenue Commissioner covers all property in the county, including Huntsville, Madison, Meridianville, and Harvest. [1]
The office keeps records on roughly 200,000 parcels. Every parcel gets an appraised value. That value is multiplied by an assessment ratio set by Alabama law to produce the "assessed value," which is the number your tax rate actually hits. Homes sit at a 10% ratio, so a house the office values at $300,000 carries an assessed value of $30,000. [2] The millage rates from the city, county, and school board then apply to that $30,000.
The Revenue Commissioner's office is in the Madison County Courthouse in downtown Huntsville. Call, walk in, or search property records through the county's online portal. Pull up any parcel by address or parcel number and you can see the current appraised value, assessed value, and tax history. That is the first thing to do if you think your assessment is wrong. Do it before you do anything else.
How does Madison County calculate your property's appraised value?
Madison County uses mass appraisal, which means the office runs statistical models across groups of similar properties instead of inspecting every home individually every year. The models pull from recent sales, replacement cost estimates, and (for commercial property) income. [2]
Residential property runs on a four-year reappraisal cycle set by Alabama law. [3] The last county-wide reappraisal wrapped in 2022, and it pushed values up hard in a lot of Huntsville-area neighborhoods because the market had been running since 2019. If your home sold recently, the office will almost certainly set your value near the sale price.
Here is how the math flows from market value to your tax bill:
| Step | What happens | Example |
|---|---|---|
| Appraised (market) value | Assessor's estimate of market value | $350,000 |
| Assessment ratio (residential) | Multiply by 10% per Ala. Code § 40-8-1 | $35,000 |
| Minus exemptions | Homestead, senior, etc. | -$4,000 |
| Net assessed value | Taxable base | $31,000 |
| Millage rate (example: 52 mills in Huntsville city limits) | Multiply net assessed x mills / 1,000 | $1,612 |
Millage rates change with location. A home inside Huntsville city limits pays a combined rate (state + county + city + school) that differs from a home in Madison or in an unincorporated area. The county posts current millage rates on its website. [1] Check the rate for your exact address before you trust any estimate.
The assessment ratio for other classes matters if you own more than a house. Farms under Class III pay 10%. Commercial and industrial property (Class II) pays 20%. Utilities pay 30%. [2]
What exemptions are available in Madison County, and how much do they save?
Alabama's exemption menu is generous, and Madison County administers all of it. You apply once and the exemption stays on the property as long as you qualify, with a few exceptions noted below. [4]
Homestead Exemption (Standard). Every owner-occupied primary residence gets a $4,000 reduction in assessed value under state law. On a home assessed at $35,000, that drops the taxable base to $31,000. It is called "Homestead Class I," and you file at the Revenue Commissioner's office. You must have owned and lived in the property as your primary residence on October 1 of the tax year. [4]
Homestead Exemption (Over-65 / Disability / Blind). Homeowners who are 65 or older, totally and permanently disabled, or legally blind may qualify for a full exemption from state property taxes plus a reduction or full exemption from county and municipal taxes, depending on income. The income limit for the full county exemption is currently $12,000 in adjusted gross income per year. [4] Over 65 but above that income limit? You still get the standard $4,000 exemption plus a pass on the state portion of the tax.
Veteran Exemptions. A veteran with a 100% service-connected disability rating from the VA pays zero property tax in Alabama on their primary residence. [5] A surviving spouse can keep the exemption. Bring the VA disability letter to the Revenue Commissioner's office. This is one of the most valuable exemptions in the state, and plenty of Huntsville-area veterans have no idea they qualify.
Current Use (Agricultural) Value. Farmland can be assessed on its current use as farmland instead of its development potential. That can slash the assessed value on acreage at the edge of the metro that the market would otherwise price as house lots. You apply with the Revenue Commissioner, and the land has to be in active agricultural use. [3]
Moved into a new home or turned 65 last year and never filed? Go file now. The office generally will not apply exemptions retroactively past the current year unless you can prove a clerical error. Waiting costs you money.
When does Madison County send assessment notices, and what are the appeal deadlines?
This is where homeowners lose money by accident. Alabama's property tax calendar does not read the way you expect.
Assessments are set as of October 1 each year. The Revenue Commissioner mails assessment notices after the reappraisal work is done, usually in the spring following the assessment date. For the 2022 reappraisal, notices went out in spring 2023.
The appeal deadline is 30 days from the date printed on your assessment notice. [6] Not 30 days from when it lands in your mailbox. Not 30 days from the tax due date. Thirty days from the date on the notice. Miss that window and your options shrink to waiting for the next reappraisal or proving a clerical error.
Alabama Code § 40-3-20 sets the 30-day window for filing a written protest with the county Board of Equalization. [6] The Board of Equalization in Madison County is a separate body from the Revenue Commissioner and holds hearings just for assessment appeals.
Tax bills are a different animal. They mail in October and are due from October 1 through December 31 with no penalty. [1] Taxes go delinquent January 1, and a 10% penalty plus monthly interest kicks in. The tax due date and the appeal deadline are two different calendars, and the appeal deadline almost always comes first.
| Event | Typical timing |
|---|---|
| Assessment date | October 1 |
| Assessment notices mailed | Spring (varies by reappraisal cycle) |
| Appeal filing deadline | 30 days from notice date |
| Board of Equalization hearing | Scheduled after filing, usually summer-fall |
| Tax bills mailed | October |
| Tax payment due (no penalty) | October 1 - December 31 |
| Taxes delinquent | January 1 |
No notice, but your value changed in the online portal? Call the Revenue Commissioner right away and get the notice date on record. The 30-day clock may still be running.
How do you appeal your Madison County property tax assessment?
The appeal runs through Alabama's Board of Equalization system. There are three levels before circuit court.
Step 1: File a written protest with the County Board of Equalization. File within 30 days of your assessment notice. [6] The protest has to be in writing, identify the property, and state why the assessed value is wrong. The Board of Equalization office for Madison County is in Huntsville. File in person or by certified mail. Keep your proof of filing.
Step 2: Build your evidence before the hearing. The Board schedules a hearing, usually 30 to 90 days after you file. At the hearing you show that the appraised value is higher than your property's true market value as of October 1. The strongest evidence is recent comparable sales ("comps") of similar homes within about a half-mile that sold below what your assessment implies. Pull them from the MLS through an agent, from Zillow's sold listings, or from Madison County deed records at the Probate Court. [1]
An independent appraisal from a licensed Alabama appraiser is the gold standard, but it runs $300 to $600 and may not pencil out on a small error. For most homeowners, three to five solid comps in a clean written summary is enough to win or negotiate a reduction.
Want a structured way to organize your comps, cover letter, and evidence packet without handing a contingency firm 30 to 40% of your savings? The TaxFightBack DIY appeal kit walks through the exact documents the Board wants to see.
Step 3: The Board's decision. The Board issues a written decision. Agree, and you are done. Disagree, and you can appeal to the Alabama Department of Revenue within 30 days of the decision, or file directly in Madison County Circuit Court. [6] Circuit court is where you would typically hire an attorney, but most residential appeals end at the Board level.
Alabama's Boards of Equalization hear tens of thousands of appeals a year statewide. The statute says the Board "shall have authority to raise or lower the assessed value" of any property. [6] The burden is on you to show the value is wrong, but a clean set of comps changes the conversation fast.
A few things that actually work in Alabama appeals:
- Bring printed copies of everything. Do not rely on email.
- Highlight the sale price, sale date, address, square footage, and lot size on each comp.
- Calculate the price per square foot for each comp and show how it lines up against your assessment.
- If the office has your square footage wrong (common with additions, garages, or plain data entry errors), say so directly. That is a factual error they have to correct.
For comparison, neighboring Shelby County's appeal follows the same Alabama statute and the same 30-day window. Shelby's fast appreciation has pushed its appeal volume high, but the same evidence approach works there.
How does Madison County compare to other Alabama counties on property tax rates?
Alabama is a low-property-tax state by national standards. The Tax Foundation ranks Alabama among the lowest effective rates in the country, roughly 0.37% of market value for owner-occupied homes. [7] That is about a third of the national median.
Inside Alabama, though, rates shift by county and municipality. Huntsville's combined millage (state + county + city + school) has run around 52 mills in recent years, which on a $350,000 home works out to roughly $1,750 a year after the standard homestead exemption. [1] Still low by Sunbelt metro standards. A similar home in Georgia's Gwinnett County (see our Gwinnett County tax assessor guide) or the Atlanta suburbs would carry a much higher effective rate.
Here is how Madison County's approximate effective rate stacks up against a few peer markets:
| County / City | State | Approx. effective rate (owner-occupied) | Source |
|---|---|---|---|
| Madison County (Huntsville) | AL | ~0.38% | Revenue Commissioner [1] |
| Shelby County (Birmingham suburbs) | AL | ~0.37% | Tax Foundation [7] |
| Gwinnett County (Atlanta suburbs) | GA | ~0.93% | Georgia DOR [9] |
| Maricopa County (Phoenix) | AZ | ~0.54% | Maricopa Assessor [10] |
| Cook County (Chicago) | IL | ~1.73% | Cook County Assessor [11] |
The low rate is real. Do not let it talk you out of appealing an inflated value. Even at 0.38% effective, an assessment that is $50,000 too high costs you about $190 a year. Over the five years before the next reappraisal, that is $950 gone.
How do I look up my Madison County property assessment online?
Use the Madison County Revenue Commissioner's property search portal on the county's official website. [1] Search by owner name, parcel number, or property address. The portal shows:
- Current appraised (market) value
- Current assessed value
- Exemptions applied
- Tax history by year
- Property characteristics used in the assessment (square footage, year built, lot size, construction quality)
That last line is the most ignored. Pull your record and compare what the office has on file to your actual home. If they show 2,200 square feet and your home is 1,950, that alone is grounds for an appeal, no comps required. Data errors like that show up more than people think, especially on older homes or homes with unpermitted work.
You can also check deed records and recent sales through the Madison County Probate Court's online system. It is separate from the Revenue Commissioner's portal but just as searchable by address.
What if I disagree with the Board of Equalization's decision?
You have two moves after the Board rules against you.
First, appeal to the Alabama Department of Revenue within 30 days of the Board's written decision. The Department has administrative law judges who hear these cases. It is still an administrative process, no filing fees, no attorney required, but more formal than the Board hearing. [6]
Second, file a petition in Madison County Circuit Court within the same 30-day window. This is where costs climb fast: attorney fees, filing costs, and months or years of delay. For a home, it rarely makes financial sense unless the disputed tax is large.
Be honest with yourself. If the Board dropped your value by $20,000 but you think it should have come down $80,000, the Department of Revenue route may be worth it. If the Board gave you nothing and the potential savings is $300 a year, a circuit court appeal will almost certainly cost more than it saves.
One thing people miss: pay your tax bill on time even while your appeal is pending. Alabama does not pause the tax due date during an appeal. Win, and you get a refund of the overpayment. Skip the payment and still win, and you owe penalties on the unpaid balance anyway. [6]
How does the Madison County assessor handle new construction and recent sales?
New construction gets assessed when a certificate of occupancy is issued or when the improvement is complete and in use, whichever comes first. The office adds the improvement value to the land value and sends a supplemental assessment notice. The same 30-day appeal window applies.
Bought recently? Expect the assessed value to move toward your purchase price. Alabama treats arm's-length sales as strong evidence of market value, and the Revenue Commissioner reviews deed transfers to update values. That is legal and expected. The real question is whether the assessment after your sale sits above or below what comparable homes sold for, not whether it matches your price to the dollar.
One quirk catches buyers off guard. You buy in November, but the assessment date is October 1, so the new value based on your sale price may not land until the following tax year. You might see two or three years of assessments before the office processes your sale. That gap is not a gift. The office catches up.
Personal property taxes in Madison County: what businesses need to know
Madison County also assesses business personal property: equipment, machinery, furniture, and inventory owned by a business. [1] Run a business anywhere in the county and you file a personal property return with the Revenue Commissioner by October 1 each year, listing all taxable personal property you owned as of that date.
Business personal property is assessed at 20% of appraised value (Class II) for most commercial property. [2] The model typically uses cost-less-depreciation schedules set by the state. You can appeal a personal property assessment through the same Board of Equalization process as real property.
Businesses overpay here constantly. If you have equipment that is fully depreciated or out of service, make sure your return shows it. The office taxes what you report. Fail to update your records and they will not automatically know your old machinery is gone.

What are the most common mistakes Madison County homeowners make with property taxes?
Missing the 30-day appeal deadline is the biggest one. There is no grace period. The Board of Equalization has no discretion to hear a late appeal under Alabama statute. [6] Toss your notice or blow past the date on it, and you wait years for the next reappraisal.
Not filing for exemptions comes second. The homestead exemption does not apply on its own. You file once, but you have to file. The over-65 and disability exemptions require annual income certification in some cases. Veterans with 100% disability ratings are owed a full exemption they routinely never claim. [5]
Taking the assessor's property data at face value is another expensive habit. The office runs mass appraisal models built on the data in their system. Bad data, bad value. Check the square footage, bedroom count, bath count, and year built on your online record before you assume the value itself is the problem.
And paying a contingency firm 30 to 40% of your savings before trying the DIY route costs most homeowners more than it saves. The Board of Equalization process is built to work without an attorney. With a clean set of comps and a one-page written summary, you can represent yourself well at a hearing. The TaxFightBack DIY appeal kit gives you the templates and checklists to do it.
Frequently asked questions
Where is the Madison County tax assessor office located?
The Madison County Revenue Commissioner's office is in the Madison County Courthouse in Huntsville, Alabama. The office handles property appraisals, exemptions, and tax collection for the entire county. You can also access property records online through the county's official website without visiting in person. Hours and contact information are posted on the Revenue Commissioner's website.
How do I appeal my Madison County property tax assessment?
File a written protest with the Madison County Board of Equalization within 30 days of the date on your assessment notice. The protest must identify your property and explain why the assessed value is wrong. Gather comparable recent sales showing lower values for similar homes, then attend your scheduled hearing. Alabama Code § 40-3-20 governs the process. There are no filing fees for residential appeals.
What is the homestead exemption in Madison County, Alabama?
Every owner-occupied primary residence qualifies for a $4,000 reduction in assessed value under Alabama's standard homestead exemption. Homeowners who are 65 or older, totally disabled, or legally blind may qualify for additional exemptions including full exemption from state property taxes, depending on income. You file once with the Revenue Commissioner's office. The application deadline is December 31 of the tax year.
What is the property tax rate in Madison County, Alabama?
Millage rates vary by location within the county. Properties in Huntsville city limits pay a combined rate of roughly 52 mills (state + county + city + school). On a $350,000 home with the standard homestead exemption, that works out to approximately $1,750 per year. The effective rate of around 0.38% is well below the national median. Check the Revenue Commissioner's website for the exact rate at your specific address.
When are Madison County property taxes due?
Tax bills are mailed in October and are due between October 1 and December 31 without penalty. Taxes become delinquent on January 1, at which point a 10% penalty plus monthly interest applies. Do not confuse this with the appeal deadline, which is 30 days from your assessment notice and typically falls much earlier in the year, before the tax bill is even mailed.
How do I look up my Madison County property assessment?
Go to the Madison County Revenue Commissioner's official website and use the property search tool. You can search by owner name, address, or parcel number. The portal shows the current appraised value, assessed value, exemptions on file, and the property characteristics (square footage, year built, etc.) that the assessor used to set your value. Checking those characteristics for errors is often the fastest way to find an appealable mistake.
Do disabled veterans get a property tax exemption in Madison County?
Yes. Alabama law exempts the primary residence of a veteran with a 100% service-connected disability rating from the VA from all Alabama property taxes. A surviving spouse can continue the exemption. You apply at the Revenue Commissioner's office and must present the VA disability determination letter. This is one of the most valuable property tax exemptions in the state and is frequently unclaimed.
How often does Madison County reassess property values?
Alabama law requires county-wide reappraisals on a four-year cycle. Madison County's most recent full reappraisal was completed in 2022. Between cycles, the assessor can update values for new construction, sales, or documented changes to the property, but most residential values hold steady until the next county-wide cycle. The next full reappraisal is expected around 2026.
What is the assessment ratio for residential property in Madison County?
Residential property in Alabama is assessed at 10% of appraised market value under Alabama Code § 40-8-1. A home the assessor values at $400,000 carries an assessed value of $40,000, and the millage rate applies to that $40,000 figure. Agricultural property is also 10%. Commercial and industrial property is 20%. Utilities are assessed at 30% of appraised value.
Can I appeal my Madison County assessment without a lawyer?
Absolutely. The Board of Equalization process is designed for property owners to represent themselves. You file a written protest, gather comparable sales or evidence of a property data error, and present your case at a scheduled hearing. Most successful residential appeals at the Board level involve no attorney at all. A lawyer makes more sense if you proceed to circuit court, which is rarely necessary for residential properties.
How does the Madison County assessor handle commercial property?
Commercial and industrial property is assessed at 20% of appraised market value, double the residential ratio. Commercial values are typically set using income or cost approaches. Businesses also file annual personal property returns for equipment, furniture, and machinery. The same 30-day Board of Equalization appeal window applies to commercial property. Commercial owners often benefit most from professional appraisals when appealing.
What happens if I miss the Madison County property tax appeal deadline?
Under Alabama Code § 40-3-20, the 30-day filing window is firm. The Board of Equalization does not have authority to hear late appeals. If you miss it, you generally wait until the next county-wide reappraisal unless you can demonstrate a clerical error in the assessment records. Pay your current tax bill on time regardless; unpaid taxes accrue a 10% penalty plus interest starting January 1.
How does Madison County's property tax process compare to Shelby County, Alabama?
Both counties follow the same Alabama statutes: 10% assessment ratio for residential property, 30-day appeal window, and Board of Equalization hearings. Shelby County, in the Birmingham suburbs, has seen similarly rapid appreciation and high appeal volumes. The Revenue Commissioner structure, exemption programs, and evidence standards are essentially identical. The main differences are local millage rates and how aggressively the office pursues comparable sales in their appraisal models.
