Rate Breakdown

Property taxes in Marengo County are calculated by multiplying the assessed value (minus exemptions) by the total local millage rate.

How Property Tax Works in Marengo County

Marengo County property tax is calculated by first determining the market value of a parcel of real or personal property. The County Assessor’s Office conducts a biennial assessment, using recent sales, appraisals and a standardized valuation formula to arrive at an “assessed value,” which is typically 40 percent of the market value for residential property. Once the assessed value is set, the tax bill is generated by applying the applicable millage rate. A mill represents one‑tenth of one percent (0.001); for example, a millage rate of 25 mills means $25 of tax per $1,000 of assessed value. The total tax due is the product of the assessed value and the combined county, city, school‑district, and any special‑district millage rates that affect the parcel.

Available Exemptions

Alabama offers several exemptions that can reduce the taxable portion of a property’s assessed value. In Marengo County, eligible owners should file the appropriate exemption forms with the Assessor’s Office each year.

• Homestead Exemption – Reduces the assessed value of a primary residence by up to $3,000 for homeowners who occupy the property as their principal dwelling.
• Senior Citizen Exemption – Residents age 65 or older may receive a $5,000 reduction in assessed value, provided they meet income eligibility limits.
• Disability Exemption – Qualified individuals with a permanent physical or mental impairment can claim up to $5,000 off the assessed value of their home.
• Veteran Exemption – Disabled veterans (or surviving spouses of a veteran who died as a result of service‑connected injuries) are eligible for a $5,000 exemption, with additional benefits for those classified as totally disabled.

All exemptions must be applied for by the annual deadline (typically March 31) and are subject to verification of eligibility each year.

Payment Schedule & Deadlines

Marengo County property taxes are payable in two installments. The first installment is due on the first business day of December, and the second installment is due on the first business day of March. Payments can be made online through the county’s tax portal, by mailed check, or in person at the County Treasurer’s Office.

• Early‑payment discount – Some municipalities offer a modest discount (usually 1 % of the installment) for payments made before the due date.
• Late payment penalties – If an installment is not received by the due date, a 10 % penalty is assessed, along with interest accruing at the state‑prescribed rate.
• Delinquency surcharge – After 60 days past due, a surcharge of $25 is added to the outstanding balance, and the county may initiate a tax lien or foreclosure process.

Taxpayers who experience financial hardship can request a payment plan from the Treasurer’s Office, but approval is discretionary and must be obtained before the original due date.

Appealing Your Assessment

If you believe your property has been over‑assessed, Marengo County provides a formal appeals process. The first step is to file a written protest with the County Assessor’s Office within 30 days of receiving the assessment notice. Include any supporting documentation—recent comparable sales, independent appraisals, or evidence of property condition—that contradicts the assessor’s valuation.

• Informal conference – An assessor may review the protest and schedule a meeting to discuss discrepancies.
• Formal hearing – If the dispute is not resolved informally, the case proceeds to the County Board of Revenue, where you may present testimony and evidence.
• Further appeal – Decisions of the Board of Revenue can be appealed to the Alabama Board of Tax Review within 45 days, and ultimately to the state courts.

Throughout the appeals process, continue to pay any tax due to avoid penalties; an appeal does not suspend the obligation to pay the assessed amount.
