Property taxes in Marengo County, Alabama

2025 reference using published Alabama millage: combined 33.5 mills (as tabulated) applied to a $350,000 residential benchmark treated as 10% taxable assessed value ($35,000), consistent with Alabama’s Class III assessment ratio for owner-occupied property—before homestead or other exemptions.
Marengo County’s ad valorem property taxes are administered locally (county revenue officials or tax collectors) using millage adopted for state, county, municipal, and school funds. This page’s millage total is reconciled to the Alabama Department of Revenue’s October 2025 county millage compilation—not a substitute for your annual notice. Incorporated areas may add municipal mills on top of the countywide stack in the state table; parcels in unincorporated areas typically follow the county and school district lines shown for your location. U.S. Census Bureau estimated 2024 county population: about 18,512.

How this compares nationally
Marengo County’s modeled effective rate here is 0.34% of this page’s benchmark. That modeled effective rate is below the broad national band many surveys use for orientation (often roughly 1–1.3% of home value, varying by source and methodology)—local bills still depend on your parcel.
Orientation band (~1–1.3%): many U.S. surveys summarize owner-occupied property taxes in that range as a share of value—definitions differ. See Tax Foundation — Property taxes as a percentage of owner-occupied housing value (state / local, illustrative national context).

Assessment & taxable value
Alabama property tax applies to taxable **assessed** value; for many residential parcels, assessed value is a defined fraction of market (Class III owner-occupied property is commonly assessed at 10% of fair market value under the constitutional assessment article—confirm your classification on the notice). Markets, caps, and exemptions mean taxable value often differs from purchase price.
Exemptions & credits
- HomesteadEstimator
Homestead exemption (Alabama)
Alabama provides a homestead exemption from the state portion of property tax, and counties may adopt additional homestead amounts under Title 40. Claim with your county tax official; deadlines are typically in the calendar year prior to the tax year.
- SeniorReference
Older taxpayers & disability exemptions
Additional exemptions may apply for taxpayers age 65 and older or with qualifying disabilities when statutory income and residency tests are met—amounts vary by locality and election.
- Veteran / militaryReference
Veterans & surviving spouses
Alabama law includes property tax relief for qualifying disabled veterans and certain surviving spouses; eligibility is documented with the county revenue commissioner or assessing official.
Homestead and other exemptions are filed with your county tax assessing or revenue office. Dollar savings depend on which county optional exemptions have been adopted—use official forms and your tax notice for parcel-specific results.

How are property taxes calculated in Marengo County?
Rate Gazetteer models here start from published millage where available (about 33.50 total mills in 2025). Ad valorem tax is generally taxable assessed value × (mills ÷ 1000), plus any non–ad valorem lines on your notice. 2025 reference using published Alabama millage: combined 33.5 mills (as tabulated) applied to a $350,000 residential benchmark treated as 10% taxable assessed value ($35,000), consistent with Alabama’s Class III assessment ratio for owner-occupied property—before homestead or other exemptions.
When are property taxes due in Alabama?
Alabama property tax due dates are set by the collecting official; many counties use an October–September tax year with bills due before the next January—check your notice.
How can I lower my property tax bill in Marengo County?
Start with your assessment notice: file for exemptions you qualify for, and use the appeal / protest process if you believe taxable value or classification is wrong. Rules and deadlines are set at the state and county level.
What is the homestead exemption in Marengo County, Alabama?
Homestead and other exemptions are filed with your county tax assessing or revenue office. Dollar savings depend on which county optional exemptions have been adopted—use official forms and your tax notice for parcel-specific results.
Why does school millage in Marengo County sometimes use an average?
Some Alabama counties list multiple school zones under “TOTAL SCHOOL.” Where there isn’t one countywide total, this page uses the mean of published zone totals as an illustration—your bill uses the zone assigned to your parcel.

Total mills combine TOTAL STATE, TOTAL COUNTY (and, where multiple TOTAL COUNTY lines are published for the county, their average as tabulated on this page), plus the school millage used in the state table. For counties where “TOTAL SCHOOL” lists multiple zone totals with no single countywide line (notably Mobile and St. Clair), school mills are taken as the **mean** of the published zone totals—an illustration only; your notice applies the millage for your school district/zone. Timber yield ($/acre) and other non–ad valorem items on the PDF footers are not included in millage. Modeled annual tax = (350,000 market × 0.1 assessment ratio) × (mills ÷ 1000); exemptions and classification change taxable value.
