How Much Can Property Taxes Increase in Alabama? 2026 Complete Guide
Updated July 2026
Quick Answer
Alabama now caps how fast your taxable assessed value can rise. Under HB73 (Act 2024-344), effective October 1, 2024, annual increases in taxable assessed value are limited to 7% for Class III property (owner-occupied homes and agricultural land) and Class II property (commercial). The cap runs through the fiscal year beginning October 1, 2027 unless the legislature renews it, and it does not apply after most ownership changes, new construction, or classification changes.
On the rate side, Amendment 373 (the 1978 Lid Bill) requires local voter approval before millage rates can be raised, so your rate cannot climb by a simple local-government decision. Owner-occupied homes are assessed at just 10% of fair market value, which is why Alabama's bills are among the lowest in the country.
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.
Alabama's New 7% Assessment Cap
For decades, Alabama had no limit on how much your assessed value could jump in a single year. That changed in 2024. HB73, enacted as Act 2024-344, caps the annual increase in taxable assessed value at 7% for Class II and Class III real property, starting October 1, 2024. Because Alabama tax years run October to September, the cap first affected the assessments homeowners saw in 2025.
Here is what that means in practice. A Class III owner-occupied home is assessed at 10% of fair market value. If your home was worth $300,000, your assessed value was $30,000. Even if the market pushed your appraised value up 15% the next year, your taxable assessed value could only rise 7%, to $32,100, instead of the $34,500 an uncapped increase would have produced. In hot markets, that difference compounds year over year.
The cap is temporary by design. It runs through the fiscal year beginning October 1, 2027 and lapses after that unless the legislature votes to renew it. As of the 2026 legislative session, no renewal or replacement had passed, so the sunset date stands.
What the Cap Does Not Cover
The 7% cap protects continuing owners of existing property. It does not shield everything. The law carves out several situations where your assessed value can jump past 7% in a single year:
- Property that has never been assessed before
- New additions and improvements (ordinary repairs and maintenance do not count)
- A change in the property's classification, such as residential to commercial
- A change in ownership, with exceptions for certain family transfers and redemptions
- Property located in a tax increment district
The ownership-change carve-out is the one that surprises people. If you bought your Alabama home recently, your first assessment can reset to full market value with no cap protection at all. That first number is the base every future capped increase builds on, which makes checking it carefully worth your time.
There is one more thing the cap never checks: whether the assessor's valuation of your home is accurate in the first place. A 7% limit on increases to a number that is too high just locks in an inflated bill and lets it grow 7% a year.
Caps and rate limits only control how fast your bill can grow. Nothing in them checks whether the number underneath is right. Assessors in Alabama set values with mass-appraisal models that price thousands of homes at once, and nobody reviews yours unless you challenge it.

What Is Alabama's Property Tax Rate in 2026?
Alabama does not have a single statewide property tax rate. Your bill is built from millage rates levied by the state, your county, your city, and your school district, and those combined rates vary from county to county. What is uniform is the assessment ratio: Class III property, which covers owner-occupied homes and agricultural land, is assessed at 10% of fair market value, and Class II commercial property is assessed at 20%. That low 10% ratio is the main reason Alabama homeowners pay some of the lowest effective property tax rates in the nation.
The rate side of the system is constrained by the state constitution. Amendment 373, known as the Lid Bill since its passage in 1978, sets constitutional ceilings on ad valorem taxation and requires local voter approval before a millage rate can be increased. Alabama does not use an annual levy-growth formula like Illinois's PTELL, but a taxing authority cannot simply vote itself a higher rate; the voters in that jurisdiction have to approve it. To find your exact 2026 millage, check your county revenue commissioner's or tax assessor's published rate schedule.
Do Property Taxes Go Up Every Year in Alabama?
They can, and in a rising market they usually do, but not without limit. Alabama counties value property on an ongoing basis and mail written valuation notices when your value changes. When market values climb, your assessed value climbs with them, now subject to the 7% annual cap for Class II and Class III property. When market values are flat, your assessed value should be flat too; there is no automatic annual escalator built into Alabama law.
So the honest answer is: your bill goes up in years when your valuation goes up or when local voters approve a new millage, and it holds steady otherwise. The 7% cap sets the ceiling on how fast the valuation side can move for a continuing owner.
Are Property Taxes Going Up in Alabama in 2026?
For most Alabama homeowners, 2026 assessments reflect the second full cycle under the HB73 cap. If your area's market values kept rising, expect your taxable assessed value to rise as well, by up to 7% if you are a continuing owner of Class III property. Homeowners who bought recently, added square footage, or changed how the property is used can see larger jumps, because those events fall outside the cap.
No new statewide property tax cap legislation passed in the 2026 session, so the rules described here are the ones governing 2026 bills. One note of caution if you research this yourself: 2026 Alabama HB392 concerns the Public Service Commission, not property taxes, despite occasionally being confused with tax legislation online.
Why Did My Property Taxes Go Up in 2026?
If your Alabama bill rose this year, it almost always traces to one of three causes. First, and most common: your assessed value went up because the county's valuation of your home went up, moving your taxable value as much as 7% higher than last year. Second, something reset your cap protection, such as a purchase, new construction, or a classification change, letting the assessment jump straight to current market value. Third, voters in your jurisdiction approved a millage increase, raising the rate applied to everyone's assessed value.
Only the first two are about your individual property, and both depend entirely on the assessor's opinion of what your home is worth. That opinion comes from a mass-appraisal model, not an individual review, and it can be wrong. If it is wrong, the appeal process exists precisely to fix it.
How Often Do Property Taxes Change in Alabama?
Valuation is an annual process in Alabama. When your county changes your property's value, it must send you a written valuation notice, and that notice starts a clock: you have 30 days from the date of the notice to appeal to your County Board of Equalization. Miss the window and you are generally locked into that value until the next notice.
Exact calendar deadlines vary by county because notices go out at different times. Mobile County's 2026 deadline, for example, fell on May 19, 2026. If you disagree with the Board of Equalization's decision, you can take the case to circuit court, but that appeal must be filed within 30 days of the Board's final decision. Your county revenue commissioner's office can confirm the dates that apply to you.
Are Property Taxes High in Alabama? How It Compares
No. Alabama consistently ranks at or near the bottom of the country for property tax burden, thanks to the 10% assessment ratio on owner-occupied homes and constitutional limits on millage. And with HB73, Alabama joined the group of states that also cap annual assessment growth, a protection it lacked before October 2024.
| State | Assessment Cap | Rate/Levy Limits |
|---|---|---|
| Alabama | 7% (Class II/III, through FY2027) | Voter approval required for millage increases (Amendment 373) |
| California | 2% | Varies |
| Florida | 3% homestead | Complex |
| Texas | 10% homestead | 3.5% + elections |
The comparison worth noticing is not the cap percentage but the base it applies to. Alabama's 7% cap is looser than California's 2%, but a $300,000 Alabama home carries a taxable assessed value of just $30,000 before millage is applied. Low base, constrained rates, and now a growth cap together keep Alabama bills small. What none of those layers do is verify that your individual valuation is fair.

HB73 (Act 2024-344) caps taxable assessed value growth at 7% for owner-occupied and commercial property.
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 to Challenge Your Alabama Assessment
When your valuation notice arrives, read the value, not just the bill estimate. You have 30 days from the notice date to file an appeal with your County Board of Equalization. The appeal is about the fair market value the county assigned to your property, so the strongest evidence is comparable sales: recent sales of similar homes in your area that support a lower value. If the Board rules against you and you still believe the value is wrong, you have 30 more days from its final decision to appeal to circuit court.
Because the 7% cap compounds from whatever base value you accept, a successful appeal does not just lower this year's bill. It lowers the starting point every future capped increase is calculated from.
A real AppealDesk order, Charlotte County, Florida
In June 2026, a homeowner in Charlotte County, Florida ran the check. The county had their home on record at $900,241, while recorded sales of comparable homes supported about $637,467: an over-assessment of $262,774, worth roughly $4,034 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 Alabama property taxes increase this year?
If you are a continuing owner of Class III property (an owner-occupied home or agricultural land) or Class II commercial property, your taxable assessed value can rise at most 7% over last year under Act 2024-344. Your actual bill can move differently if local voters approved a millage change, and the cap does not apply if you recently bought the property, made improvements, or changed its classification.
Does the 7% cap mean my tax bill can only go up 7%?
Not exactly. The cap limits growth in taxable assessed value, which is the biggest driver of your bill, but the bill itself also depends on millage rates. Rates can rise if voters in your jurisdiction approve an increase under Amendment 373. And if your property falls into one of the cap's exclusions, your assessed value can jump well past 7% in a single year.
How long does Alabama's assessment cap last?
The cap runs through the fiscal year beginning October 1, 2027. After that it lapses unless the legislature renews it. Nothing passed in the 2026 session changed that timeline, so homeowners should watch the 2027 session for a renewal or replacement.
How often is my property reassessed in Alabama?
Counties value property on an ongoing annual basis and send a written valuation notice when your value changes. That notice is the trigger that matters: it opens your 30-day window to appeal to the County Board of Equalization. Notice timing varies by county, so confirm your local schedule with your county revenue commissioner.
What is the best way to control my property tax increases?
Verify the valuation on every notice you receive, appeal within 30 days when the value looks high, and make sure you are claiming the homestead exemption and any other programs you qualify for. The cap handles the growth rate automatically; the accuracy of the underlying value is on you to check.
