When buyers compare homes in Madison, they usually worry about two things: which side of the county line a house sits on, and whether Alabama's new assessment cap will reset after they buy. Both are real. At the typical Madison-area price, though, both are small next to a third factor that rarely comes up. The tax figure on a listing reflects the seller's tax class and any exemptions the seller earned. Those can move the bill by hundreds of dollars a year, sometimes by thousands, and they stop at closing.
The numbers below show the scale of each factor, using the most recent local price data and the state's own millage tables.
Start with the house the seller actually owned
Alabama taxes an owner-occupied single-family home on 10% of its appraised value. That is Class III. A home that isn't owner-occupied, including a rental, generally falls into Class II at 20%, as the Alabama Department of Revenue explains. Mills then apply to that assessed value. One mill is $1 per $1,000 of assessed value, not market value.
The examples use the August 2026 single-family median for Huntsville/Madison County, which was $348,955 according to the ValleyMLS Monthly Indicators report published by HAAR. That report covers a market area defined by high schools, Bob Jones and James Clemens among them, rather than Madison city by itself. The rate is 69.5 mills, the sum of the October 2025 state, county, school, and municipal rates for a Madison-city parcel on the Madison County side. Here is the same house under different owners:
| Who owned it | How it's assessed | Approximate annual tax |
|---|---|---|
| A landlord | Class II, 20% | about $4,850 |
| An owner-occupant without a homestead on file yet | 10% rate | about $2,425 |
| An owner-occupant under 65 with the regular homestead | 10% rate plus H-1 | about $2,377 |
| An owner 65 or older with income over $12,000 | 10% rate plus H-4 | about $2,176 |
| An owner 65+ under the income limit, or permanently and totally disabled | H-3 | exempt from all ad valorem taxes |
These are approximations. ADOR notes that exemptions are limits on assessed value, applied portion by portion against state, county, and school millage. They are not flat deductions from the final bill. The spread between the rows is still the point. The biggest gap has nothing to do with exemptions. It is the gap between 10% and 20% assessment, which roughly doubles the bill. If the house you're looking at was a rental, its tax history is reporting a different tax class than the one you would be in.
The regular homestead exemption is smaller than most people expect. On its homestead exemption page, the Madison County Tax Assessor describes it this way:
In addition to placing the property in a 10% tax class, the owner receives approximately a $48 per year savings.
That $48 matches the H-1 math. It is a $4,000 assessed-value exemption on the 6.5 state mills plus a $2,000 exemption on the 11 county mills. The over-65 categories go further. H-4 exempts the entire state portion. H-3 exempts the owner from all ad valorem taxes. These exemptions belong to the qualifying owner, so they end when the home sells. A longtime owner's tax line can look like a bargain for exactly that reason.
The county line is worth less than a month of streaming services
The City of Madison crosses into Limestone County. WAFF reported in February 2024 that homeowners near Hardiman Road, including residents off Wesley Clark Boulevard, live inside Madison city limits but in Limestone County.
On the Limestone side, the state, school, and municipal rates are the same as in Madison County: 6.5 state mills, 5.5 Madison school mills, and 46.5 Madison municipal mills. The county levy is 13.5 mills, against 11.0 on the Madison County side, for a total of 72.0 mills. All of the extra 2.5 mills come from the county portion. Limestone's county levy includes a 3.0-mill hospital tax, and Madison County's does not.
At the August 2026 median, that comes to about $2,512 a year on the Limestone side and about $2,425 on the Madison County side, before exemptions. The difference is roughly $87 a year. It's real money. It is also a small fraction of what a seller's tax class or senior exemption can account for. All of these figures come from the October 2025 state table. Research for this post did not find a 2026 table or a newer local millage vote, so confirm current rates with the county before you rely on them.
Where the county line matters more is the paperwork. In Madison County, a Tax Assessor appraises and assesses, and a separate Tax Collector collects. In Limestone County, one office, the Revenue Commissioner, handles assessment and collection and grants exemptions. Deeds are recorded with the Probate Judge in whichever county the parcel sits in.
The cap reset has had very little to reset
Alabama's Act 2024-344 limits annual increases in taxable assessed value to 7% for Class II and Class III property. The base year began October 1, 2024, and the first collections under the cap started October 1, 2025. According to the ADOR cap page, a change in ownership removes the cap. The cap stays in place when a home moves between spouses or family members for no or nominal consideration, or because the owner died. Adding onto a house or making a significant improvement also removes the cap. Ordinary maintenance does not.
The reset only costs a buyer money if a home's true value has outrun its capped value, and local prices have been close to flat. HAAR's annual reports put the Madison County median at $331,515 for 2023, $332,065 for 2024, and $332,129 for 2025. HAAR described this as "a period of price leveling following earlier growth." In August 2026, the single-family median was up 2.6% from a year earlier. The cap only kicks in when true assessed value rises more than 7% in a year, so a typical Madison-area home has had little reason to hit it. The homes most likely to show a gap are ones that rose well above the market trend. A house with a recent addition is another matter. The cap's reset rules don't hide anything there, because an addition already removes the cap.
Why your first October bill can still surprise you
Exemptions and tax class explain why the bill changes. Timing explains when you find out. ADOR says property taxes are due October 1 and become delinquent after December 31. Madison County's collector lists January 1 as the delinquent date. The 2026 bills came due eleven days ago.
The Alabama Association of REALTORS Legal Helpdesk describes how this shows up at closing:
- State and county taxes are assessed in arrears. The seller usually credits the buyer for the seller's share, because the buyer pays the full bill the following October.
- Municipalities may assess in advance. In that case, the buyer may reimburse the seller for municipal taxes the seller already paid.
- The split is based on estimated taxes, so the actual bill can come in higher.
That last point is where the seller's exemptions catch up with a buyer. If the estimate starts from a bill that carried an H-4 or H-3 exemption, or was calculated before a reassessment, the proration credit can be smaller than the bill that arrives the next October. Madison's municipal levy is 46.5 mills, 33.5 of them for education. It is the largest piece of the total. Your closing attorney or title company can tell you how the city portion is handled in your proration.
Filing your own homestead, especially if you're relocating
Madison County grants a homestead when the home is the owner's primary residence on October 1, and the deadline to apply is December 31. You will need a deed and a driver's license that shows the property address and was issued on or before October 1. If you change your license address between October 1 and December 31, the county also asks for a homeowner's insurance policy and a set-date letter from Huntsville Utilities.
The county's rules include a few details that help buyers moving from out of state:
- Out-of-state license. Until your Alabama license matches the new address, the county can grant the 10% rate if you bring the insurance declaration page covering October 1 and the Huntsville Utilities set-date letter. You add the homestead later.
- Active-duty military. An active-duty ID plus the insurance policy and set-date letter works without changing your license.
- Homestead elsewhere. If you still claim a homestead on another home, the county asks for a letter on the prior taxing official's letterhead confirming you no longer claim it there.
On the Limestone side, the Revenue Commissioner says owner-occupants claim the homestead at assessment, special exemptions have to be filed every year, and an acquired property has to be assessed by December 31. The sources don't agree on one point. Limestone's page says its regular exemption excludes school and municipal taxes. ADOR's statewide table describes the ordinary county exemption differently. If you're buying west of the county line, ask the Revenue Commissioner directly how it applies.
FAQ
Can I see what the seller was paying and adjust it myself? Yes. Start with the seller's tax class and exemption codes. If the home was a rental or carried an over-65 exemption, the next owner's bill will be built on different inputs, and the millage won't explain the difference.
Does buying a newly built home in Madison change any of this? A new home that has never been assessed sits outside the cap until it has been assessed, according to ADOR. Its first full assessment reflects its full value.
Who answers questions about a specific parcel? In Madison County, it's the Tax Assessor at 256-532-3350. In Limestone County, it's the Revenue Commissioner's office.
