Rate Breakdown

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

How Property Tax Works in Dekalb County

Every property in Dekalb County is assigned a fair market value by the County Assessor’s Office. This “assessment” is typically updated every four years, but the Assessor may also conduct interim adjustments if significant improvements or damages occur. Once the assessed value is established, the county applies its millage rates to determine the annual tax bill.

A “mill” represents one‑thousandth of a dollar. For example, a millage rate of 30 mills equals $30 in tax for every $1,000 of assessed value. Dekalb County’s overall rate combines several components:

• County General Fund: Funds county services such as law enforcement, road maintenance, and public health.
• School District: The main portion of the bill, supporting Dekalb County School System operations.
• Municipal/City Rates: If the property lies within a city, the city’s millage is added.
• Special Districts: Includes fire, water, or sanitation districts that levy additional mills.

The total millage rate fluctuates yearly based on budget needs and voter‑approved levies. To calculate your tax: multiply the assessed value (in dollars) by the total millage rate, then divide by 1,000.

Available Exemptions

Dekalb County follows Alabama state law, which provides several exemptions that can lower your taxable value.

• Homestead Exemption: Homeowners who occupy the property as their primary residence may claim an exemption up to $5,000 of assessed value. An application must be filed with the County Assessor by June 1 of the tax year.
• Senior Citizen Exemption: Residents aged 65 or older who meet income limits (generally $30,000 household income) can receive an additional $5,000 exemption.
• Disability Exemption: Persons with a qualifying physical or mental disability may also claim a $5,000 exemption, provided they file the appropriate documentation.
• Veteran Exemption: Honorably discharged veterans, and in some cases their surviving spouses, are eligible for a $5,000 exemption. Disabled veterans may qualify for a larger reduction based on disability rating.

Exemptions are applied to the assessed value before the millage rate is calculated, effectively reducing the tax bill. All exemptions require a completed application and supporting proof (e.g., birth certificates, disability statements, DD 214). Once approved, exemptions remain in effect for subsequent years unless the owner’s circumstances change.

Payment Schedule & Deadlines

Dekalb County’s property tax bill is typically issued in July. Taxpayers have two primary options for payment:

• Full Payment: Pay the entire amount by the first Friday in October to avoid interest.
• Installment Plan: Pay half of the bill by the first Friday in October and the remaining balance by the first Friday in January. The county may charge a modest administrative fee for the split‑payment option.

Late payments incur a 5% penalty after the October deadline, plus interest calculated at the state‑prescribed rate of 2% per month on the delinquent balance. Continued non‑payment can lead to a tax lien, and the county may initiate a tax sale to recover owed amounts.

Appealing Your Assessment

If you believe your property has been over‑assessed, Dekalb County offers a structured appeals process:

• File a Petition: Submit a written petition to the County Assessor’s Office within 30 days of receiving your assessment notice. Include supporting evidence such as recent sales of comparable properties, an independent appraisal, or documented errors.
• Review by the Board of Equalization: The petition is forwarded to the Board of Equalization, which holds a public hearing. You may present your case in person or through an authorized representative.
• Decision & Further Appeal: The Board issues a written decision within 45 days. If the decision is unsatisfactory, you may appeal to the Circuit Court of Dekalb County within 30 days of the Board’s ruling.

Keeping thorough records, photographs, and market data will strengthen your case. Most successful appeals result from clear, comparable sales evidence rather than subjective opinions of value.
