Property tax in Alabama is among the lowest in the country, with an effective rate averaging roughly 0.38% of market value. The reason is built into the state constitution: Alabama taxes only a fraction of what your property is actually worth, and owner-occupied homes are taxed on just 10% of their value. Homestead exemptions can reduce the bill further, and for many seniors and disabled homeowners, eliminate it entirely.
How Your Bill Is Calculated
Three numbers produce your tax bill: the fair market value the county assessor puts on your property, the assessment rate tied to your property’s class, and the total millage rate for your location.
Amendment 373 sorts every taxable property into one of four classes, each with its own assessment rate:1Justia. Alabama Constitution – Amendment 373
- Class I (30%): utility property used in business operations.
- Class II (20%): the catch-all for property that doesn’t fit another class, including commercial buildings, industrial equipment, and vacant investment land.
- Class III (10%): agricultural land, forest land, single-family owner-occupied homes, and historic buildings.
- Class IV (15%): private passenger cars and personal-use pickup trucks.
Most homeowners land in Class III, and the 10% assessment rate is the single biggest reason bills stay low. A home appraised at $200,000 has an assessed value of $20,000 before millage is applied.
A mill equals $1 of tax per $1,000 of assessed value. If your combined millage rate is 50 mills, the math on that $20,000 assessed value is $20,000 × 0.050 = $1,000 for the year.2Alabama Department of Revenue. Property (Ad Valorem) Tax
Your combined millage is a stack. Alabama imposes 6.5 mills statewide, and your county commission, school district, and any municipality each add their own. Rural counties often sit in the 25 to 30 mill range; urban areas and well-funded school districts can push past 60 or 70. Your county tax assessor or revenue commissioner can give you the exact figure for your address.
Homestead Exemptions
If you own and live in a single-family home in Alabama on October 1 of the tax year, and the property doesn’t exceed 160 acres, you can apply for a homestead exemption that reduces your assessed value before taxes are calculated. Alabama uses a tiered system based on age, income, and disability.3Alabama Department of Revenue. Homestead Exemptions
Standard Exemption (H-1)
Any homeowner under 65 who is not disabled qualifies for H-1: $4,000 off the assessed value for state taxes and $2,000 off for county taxes. On a home with a $20,000 assessed value, that leaves $16,000 taxable by the state and $18,000 by the county.
Senior and Disability Exemptions (H-2, H-3, H-4)
The savings jump once you turn 65 or qualify as permanently and totally disabled:
- H-2: For homeowners 65 or older with adjusted gross income under $12,000, or anyone retired due to permanent and total disability regardless of age. Eliminates the state portion and provides a $5,000 county exemption.
- H-3: For homeowners 65 or older whose combined net taxable income on the federal return is $12,000 or less, or anyone permanently and totally disabled regardless of income. Eliminates all property taxes, including state, county, and municipal levies.
- H-4: For homeowners 65 or older with income above $12,000 on their Alabama return. Eliminates the state portion and provides the standard $2,000 county exemption.
The H-3 exemption has no income cap for disabled homeowners. A permanently and totally disabled owner earning well above $12,000 still pays zero property taxes.
Legally blind homeowners also receive exemptions from state property taxes regardless of age or income.4Alabama Administrative Code. Alabama Administrative Code 810-4-1-.23 – Homestead and Principal Residence Exemptions From Property Tax
How to Apply
Apply at your county tax assessor’s office. Bring your deed or other proof of ownership, a current utility bill showing the address, and your most recent tax return. For a disability exemption, Alabama requires a physician’s certification on Form PT-PA-1 signed by two licensed Alabama physicians, at least one of whom is actively treating your disability. For age-based exemptions, a driver’s license is sufficient proof.4Alabama Administrative Code. Alabama Administrative Code 810-4-1-.23 – Homestead and Principal Residence Exemptions From Property Tax
Once approved, the exemption stays in place as long as you own and occupy the property. If you move, sell, or your income changes in a way that affects eligibility, notify the assessor’s office. Failing to do so can cost you the exemption and leave you owing back taxes.
When Property Taxes Are Due
Alabama collects property taxes in arrears. The bill you receive in the fall covers the tax year that already ended, and your assessment reflects the property’s status and value as of October 1 of the prior year.5Alabama Department of Revenue. When Are My Property Taxes Due?
- October 1: bills become due.
- December 31: last day to pay without penalty. Payments postmarked by this date are on time.
- January 1: unpaid taxes become delinquent, and interest and late fees begin to accrue.
- February: delinquent accounts are turned over to the probate court.
- May: tax sale is held.
That timeline moves fast. A homeowner who misses December 31 is about five months from a tax sale, and the state does not send multiple rounds of reminders before starting the process.
What Happens if You Don’t Pay
After delinquency on January 1, the county adds interest and fees, and the property eventually goes to a tax lien auction. The purchaser at that auction receives a tax lien certificate. The certificate does not transfer ownership; it gives the holder the right to collect what you owe, plus interest.6Alabama Legislature. Code of Alabama 40-10-187
You have three years from the date of the tax sale to redeem the property by paying all delinquent taxes, fees, and penalties at 12% interest per year.7Alabama Department of Revenue. Do I Have the Option to Redeem My Tax Delinquent Property? That rate compounds quickly. A $1,000 delinquent bill grows to $1,360 in principal and interest alone after three years, before additional fees.
If the certificate has been held for more than three years without redemption, the purchaser can obtain a tax deed. Even then, the deed doesn’t automatically convey clear title, so the purchaser typically has to file a quiet title action. From the original owner’s perspective, once the three-year window closes, recovering the property becomes extremely difficult and expensive.8Alabama Department of Revenue.

Appealing Your Valuation
If the county appraised your property too high, you can challenge the valuation by filing a written protest with your county Board of Equalization. You have 30 days from the date you receive written notice of the assessed value to file.9Alabama Department of Revenue. What Can I Do if I Do Not Agree With the Value on My Property?
Bring evidence that supports a lower number: recent comparable sales in your neighborhood, an independent appraisal, photographs of condition issues the assessor may have missed, or documentation of value-reducing factors like flood zone designation or structural problems. Comparable sales showing the county’s number exceeds what similar nearby homes actually sold for is the strongest evidence.
If the Board rules against you, you can appeal to the circuit court.
How to Pay
Your county tax collector or revenue commissioner handles payments. Most counties offer online portals; credit card payments usually carry a convenience fee of about 2% to 2.5%, and e-check payments are typically cheaper or free. You can also pay by mail using the envelope included with your notice, or in person at the county courthouse or a satellite office. Get a receipt either way. That receipt is your proof the lien has been cleared for the year.
If you have a mortgage, your lender likely collects taxes through an escrow account and pays the bill in October. Even so, it is worth checking your county’s records once a year to confirm the payment posted. Lender mistakes happen, and the tax lien attaches to the property regardless of who was supposed to pay it.
