Alabama property tax is calculated by multiplying your property’s assessed value by the local millage rate, where the assessed value is a fixed percentage (10%, 15%, 20%, or 30%) of fair market value depending on how the property is classified. The state sets the classification rules and assessment ratios; your county, city, and school district set the millage. That combination produces some of the lowest effective property tax bills in the country, but only if you claim the exemptions you qualify for and pay on time.
How Your Tax Bill Is Calculated
The formula is short: assessed value multiplied by the millage rate equals your tax. A mill is one-tenth of a cent, so one mill on $1,000 of assessed value produces $1 of tax.
Take a home with a fair market value of $200,000. Residential property is assessed at 10%, so the assessed value is $20,000. If the combined county, municipal, and school millage where the home sits totals 50 mills, the annual bill is $1,000 before any exemptions. Millage rates vary significantly county to county, and the Alabama Department of Revenue publishes them each year.1Alabama Department of Revenue. Property Tax Assessment
The Four Property Classes and Assessment Ratios
Every taxable property in Alabama falls into one of four classes, written into the state constitution and codified effective October 1, 1978. Each class carries a fixed assessment ratio:
- Class I, utility property owned by utilities and used in their business: 30% of market value.
- Class II, all other property (commercial real estate, business personal property, anything that doesn’t fit the other three): 20%.
- Class III, agricultural, forest, residential, and historic property: 10%. Historic property qualifies regardless of how it is used.
- Class IV, personal-use passenger cars and pickup trucks owned by an individual and not used for hire or compensation: 15%.
Classification is not a choice. Your county assessor applies the class based on the property’s actual use, and the ratios are statutory.2Alabama Legislature. Alabama Code Title 40 Chapter 8 – 40-8-1 Classification of Property
Homestead Exemption for Alabama Homeowners
If you own and occupy your home as a primary residence, you qualify for a homestead exemption. What you get depends on your age, disability status, and income.
Under Age 65
Your homestead is exempt from all state property taxes on the first $4,000 of assessed value. You also get a county exemption on the first $2,000 of assessed value, though it does not cover countywide school district taxes. Your county’s governing body may raise the county exemption up to $4,000 by local resolution. The exemption is capped at 160 acres regardless of the dollar figures.3Alabama Legislature. Alabama Code Title 40 Chapter 9 – 40-9-19 Homesteads
Age 65 and Older, Permanently and Totally Disabled, or Legally Blind
You receive a complete exemption from all state property taxes on your homestead, with no cap on assessed value.3Alabama Legislature. Alabama Code Title 40 Chapter 9 – 40-9-19 Homesteads
If your annual adjusted gross income is also less than $12,000, your homestead is exempt from county property taxes, including school district taxes, on the first $5,000 of assessed value and up to 160 acres. The figure comes from your most recent Alabama income tax return. If you aren’t required to file, a signed affidavit showing income under $12,000 is enough.3Alabama Legislature. Alabama Code Title 40 Chapter 9 – 40-9-19 Homesteads
Separate Exemption Under Section 40-9-21
A separate statute exempts the principal residence and up to 160 acres of anyone who is permanently and totally disabled, or who is 65 or older with combined federal taxable income of $12,000 or less on the most recent U.S. return (yours and your spouse’s). This exemption applies to all ad valorem taxes on that property.4Alabama Legislature. Alabama Code Title 40 Chapter 9 – 40-9-21 Principal Residences and 160 Acres
Proving permanent and total disability requires written certification from two licensed Alabama physicians, at least one of whom is actively treating the condition. Veterans receiving a service-connected disability pension are automatically issued a disability certificate by the Alabama Department of Revenue and do not need separate physician documentation. The property must be a single-family home you own and occupy as your principal residence during the tax year; second homes, rentals, and vacant land don’t qualify.4Alabama Legislature. Alabama Code Title 40 Chapter 9 – 40-9-21 Principal Residences and 160 Acres
Current Use Valuation for Farm and Timber Land
Class III agricultural and forest property can qualify for a further reduction through Alabama’s current use program. Under current use, the assessor values your land at what it is worth as farmland or timberland rather than what a developer would pay. Near a growing city or a highway corridor, the gap between market value and current use value can be large.
To qualify, the land must be actively used for raising crops, feeding or breeding livestock, or growing timber. Apply through your county assessing official between October 1 and January 1. Once approved, the current use classification continues as long as the qualifying use continues. Convert the land to another use, and the property reverts to fair market value assessment. You may owe rollback taxes covering the difference for prior years.5Alabama Department of Revenue. Current Use
Payment Deadlines and Delinquency
Property taxes become due on October 1 each year and delinquent after December 31. Once January 1 arrives, interest starts accruing at 12% per year and a fast enforcement timeline begins:6Alabama Department of Revenue. When Are My Property Taxes Due?
- January 1: taxes delinquent, 12% annual interest begins.
- February: delinquent accounts turned over to probate court.
- March: probate court convenes on unpaid taxes.
- April: properties advertised for tax sale.
- May: tax sale.
A homeowner who misses the December 31 deadline can see the property advertised for sale about four months later. If you cannot pay in full, contact your county tax collector before the property is turned over to probate rather than after.6Alabama Department of Revenue. When Are My Property Taxes Due?
Redemption After a Tax Sale
A tax sale does not immediately cost you the property. Alabama law gives the original owner, heirs, mortgage holders, and anyone else with a legal interest a three-year period to redeem.7Alabama Legislature. Alabama Code Title 40 Chapter 10 – 40-10-120 When and by Whom Redemption May Be Made
Redemption means repaying the full amount of delinquent taxes, penalties, fees, and costs the purchaser paid, plus interest. For tax sales occurring after January 1, 2020, the redemption interest rate is 8% per year. The delinquent taxes themselves accrue 12% annual interest from the date of delinquency until the sale.8Cornell Law Institute. Alabama Admin Code 810-4-6-.02 Reduction of Interest Rate on Redemptions of Tax Lien Sales
If no one redeems within three years, the purchaser can file a foreclosure and quiet title action to take permanent ownership. Minors and legally incapacitated persons get an additional year after the removal of their disability to redeem.7Alabama Legislature. Alabama Code Title 40 Chapter 10 – 40-10-120 When and by Whom Redemption May Be Made
Appealing Your Assessment
If you think your assessed value is too high, you can challenge it. File a written protest with the county Board of Equalization within 30 days of receiving notice that your valuation has changed. A county appraiser reviews the property. If you are still unsatisfied, the Board holds a formal hearing where you present evidence.
The evidence that carries weight in Alabama assessment appeals is usually recent sale prices of comparable nearby properties, a professional appraisal showing a lower value, or documentation of property condition issues that reduce market value. After the Board issues its decision, you have 30 days to appeal to circuit court. To preserve that right, pay your taxes by December 31 or file a bond in circuit court for double the amount of taxes due.
Federal Deduction for Property Taxes You Pay
Alabama property taxes on your home are deductible on your federal return if you itemize, as part of the state and local tax (SALT) deduction. For 2026, the SALT cap is $40,400 for most filers and $20,200 for married filing separately, covering the combined total of state income taxes, local taxes, and property taxes.9Internal Revenue Service. Potential Tax Benefits for Homeowners
Because Alabama property tax bills are low relative to most states, most homeowners will not hit the SALT cap on property taxes alone; the cap tends to matter once state income taxes are added in. Uniformed service members and ministers who receive a nontaxable housing allowance can still deduct their full property taxes without reducing the deduction by the allowance amount.9Internal Revenue Service.
