Alabama Department of Revenue: Taxes, Fees, and Compliance

The Alabama Department of Revenue (ADOR) administers the state's tax laws, licensing programs, and fee structures under the authority granted by the Alabama Legislature. This page covers the department's organizational scope, the primary tax types it administers, how compliance obligations are structured, and the boundaries that distinguish state-level revenue administration from federal and local jurisdiction. Understanding ADOR's role is essential for businesses, property owners, and individuals subject to Alabama tax law.

Definition and scope

The Alabama Department of Revenue is the executive agency responsible for collecting state taxes, administering tax laws, and enforcing compliance across Alabama's 67 counties. ADOR operates under Title 40 of the Code of Alabama 1975, which codifies the state's revenue and taxation statutes (Code of Alabama, Title 40).

ADOR's administrative scope includes:

  1. Individual Income Tax — imposed on Alabama-source income for residents and nonresidents under Code of Alabama §40-18-1 et seq.
  2. Corporate Income Tax — a flat rate of 6.5% on net income attributable to Alabama (ADOR Corporate Income Tax)
  3. Sales and Use Tax — a state base rate of 4% on retail sales of tangible personal property, with municipal and county rates applied in addition (ADOR Sales Tax)
  4. Property Tax — administered through ADOR's Property Tax Division in coordination with county assessors across all 67 counties
  5. Rental Tax — Alabama imposes a rental tax on the leasing of tangible personal property, a tax type absent from most states
  6. Utility Gross Receipts Tax — levied on utility services delivered within Alabama
  7. Tobacco, Alcohol, and Motor Fuel Taxes — administered through dedicated divisions within ADOR

The department also issues licenses required for sales tax collection, motor fuel distribution, tobacco distribution, and other regulated commercial activities.

Scope boundary: ADOR's authority applies exclusively to Alabama state-level taxes and fees. Federal income tax obligations are administered by the Internal Revenue Service and fall outside ADOR's jurisdiction. Municipal and county sales taxes, though often collected in conjunction with the state rate, are governed by local ordinance; ADOR may collect them on behalf of local governments under voluntary participation agreements, but disputes involving local-only rates are resolved outside ADOR's administrative appeals process. Activities governed by tribal compacts or federal preemption are not covered by state revenue statutes.

How it works

ADOR is organized into functional divisions: Individual and Corporate Tax, Sales and Use Tax, Property Tax, Motor Vehicle, Compliance and Appeals, and IT/Administrative Services. Each division administers its tax type from registration through audit and collection.

Filing and remittance: Alabama businesses register through the My Alabama Taxes (MAT) portal (MAT portal), ADOR's online compliance platform. Sales tax returns are due monthly for dealers with annual liability exceeding $2,400; quarterly filing applies to lower-volume filers. Individual income tax returns follow the federal calendar, with an April 15 due date and a six-month extension available.

Withholding: Employers subject to Alabama payroll withholding must register with ADOR and remit withheld income tax on a schedule tied to the aggregate withholding amount. Employers withholding more than $1,000 per month file and remit monthly; those below that threshold remit quarterly.

Audits and assessments: ADOR's Compliance Division conducts field audits, desk audits, and data-matching reviews. A formal Notice of Final Assessment triggers the appeals process under Title 40, Chapter 2A. Taxpayers may appeal to the Alabama Tax Tribunal, an independent adjudicative body established by the Alabama Tax Tribunal Act of 2014, before pursuing circuit court review.

Penalties and interest: Late payment of Alabama income tax incurs a penalty of 10% of the unpaid tax plus interest at the applicable federal underpayment rate plus 2 percentage points (Code of Alabama §40-2A-11).

Common scenarios

Retail business registration: A business making retail sales in Alabama must obtain a Sales Tax License from ADOR before commencing operations. The license fee is $15 per location. The licensee collects the 4% state sales tax plus applicable local rates and remits them through MAT.

Remote seller compliance: Following the U.S. Supreme Court's 2018 decision in South Dakota v. Wayfair, Alabama adopted economic nexus standards. Remote sellers with more than $250,000 in Alabama sales annually are required to register and collect Alabama sales tax (ADOR Remote Sellers).

Property tax assessment: County assessors value real and personal property; ADOR supervises assessment methodologies and equalization. Agricultural property is assessed at 10% of appraised value, while commercial property is assessed at 20%, and residential property at 10% (ADOR Property Tax).

Rental tax on equipment: An Alabama business leasing construction equipment within the state owes rental tax at a state rate of 4%, separate from any sales tax obligation. This scenario often catches out-of-state lessors operating temporarily in Alabama.

Decision boundaries

State vs. local tax disputes: If a dispute involves only a county or municipal add-on rate collected by ADOR under an agreement, the local government — not ADOR — is the proper respondent. The Alabama Tax Tribunal does not have jurisdiction over purely local tax disputes absent a state component.

State vs. federal jurisdiction: Alabama individual income tax does not conform fully to federal tax law. Alabama uses federal adjusted gross income as a starting point but applies state-specific modifications, including deductions for federal income taxes paid. A federal audit adjustment that changes federal taxable income may trigger an amended Alabama return obligation under Code of Alabama §40-18-33.

Resident vs. nonresident filers: A full-year Alabama resident files on all income regardless of source. A nonresident files only on Alabama-source income. A part-year resident allocates income between resident and nonresident periods. The distinction affects both the filing form used and the applicable deduction calculations.
