Alabama has a 4% state sales tax but some of the highest combined rates in the country due to city and county additions. Birmingham, Mobile, and Montgomery all reach 10%. Alabama also taxes groceries, creating one of the highest everyday tax burdens in the US.
How Alabama Sales Tax Works
Alabama levies a 4% state sales tax. Cities and counties add aggressively on top, resulting in some of the highest combined sales tax rates in the US. Alabama is also one of the few remaining states that taxes groceries, making everyday shopping more expensive for residents.
Retailers, restaurants, and service providers with taxable sales must show tax separately or include it in shelf prices per AL law. Tax holidays, if offered, temporarily change rates for qualifying items — watch Department of Revenue announcements each summer.
Alabama combined rates by city
Combined rates vary across Alabama. Reference cities on this page include: Birmingham (10%), Mobile (10%), Montgomery (10%), Huntsville (9%), Tuscaloosa (10%), Hoover (9%). ZIP codes and special districts can differ — use the official lookup linked above for address-level filing.
District taxes in Birmingham reflect State 4% + County 1% + City 4% + Special 1%. Revalidate after annexation or ballot measures that add transportation or cultural district levies.
Common exemptions in Alabama
Common exemptions include: Prescription drugs; Medical equipment; Agricultural production items. Restaurant meals, prepared food, and many services are often taxable even when groceries are exempt.
Resale and manufacturing exemptions require certificates and proper record retention. Charging tax on exempt sales creates refund liability; failing to charge on taxable sales creates assessment risk plus interest.
Online sellers and economic nexus
Out-of-state sellers that exceed $250,000 in Alabama sales in the prior calendar year in Alabama generally must register and collect tax on taxable sales delivered into the state. Marketplace facilitators often remit tax on behalf of third-party sellers.
Registration portals issue filing frequencies and due dates. Voluntary disclosure agreements may reduce penalties if you discover historical under-collection — consult AL DOR or a state tax adviser before registering retroactively.
How to use this calculator
Pick a city from the list or type the combined percentage from your AL tax lookup. Enter a pre-tax amount to add sales tax, or use reverse mode to split tax from a receipt total. Businesses should validate address-level rates in certified tax software before filing returns.

Calculating Alabama sales tax step by step
Forward: Tax = taxable price × (combined rate ÷ 100). On $250 at 9.24% average combined, tax ≈ $23.1 and total ≈ $273.1. Reverse: Pre-tax = total ÷ (1 + rate ÷ 100).
Use the exact city rate when known — averages are for benchmarking only. Multi-item carts should compute tax per taxable line; do not apply one rate to a basket containing exempt groceries and taxable snacks without splitting lines.
Finding the correct Alabama sales tax rate
Alabama starts with a 4% state-level sales tax on taxable sales. County, city, and special district taxes stack on top, so two addresses in the same ZIP can differ when district boundaries split the area. Birmingham is listed at 10% combined on this page. Never quote customers using only the state rate when local taxes apply — combined rates are what cash registers and marketplaces must use for destination-based shipments.
Official AL Department of Revenue rate finders accept street address or ZIP+4 for filing-grade accuracy. Our calculator uses reference cities for speed; export the exact percentage from the state tool before remitting on a return. Update ecommerce tax tables whenever Alabama publishes bulletin changes, typically quarterly or after legislative sessions.
What is taxable vs exempt in Alabama
Commonly taxable in Alabama: General merchandise, Electronics, Clothing, Restaurant meals. Common exemptions or reduced rates include Prescription drugs, Medical equipment, Agricultural production items. Restaurant meals, catering, and prepared food are usually taxable even when grocery ingredients are exempt. Digital products, SaaS, and streaming may be taxable depending on AL statutes — check current guidance rather than assuming one rule nationwide.
Clothing and footwear rules vary: some states exempt apparel under price caps while Alabama may tax full price. Medical devices and prosthetics often need specific documentation. For mixed invoices, calculate tax per line instead of one blended rate on the subtotal unless Alabama explicitly allows a single rate on the entire basket.
Remote sellers, marketplaces, and nexus in Alabama
Out-of-state and marketplace sellers that exceed $250,000 in Alabama sales in the prior calendar year in Alabama generally must register, collect, and remit sales tax on taxable sales delivered into the state. Facilitators like Amazon and Walmart often report and pay on behalf of third-party sellers, but the seller remains responsible for accurate product tax codes and exemption paperwork.
Destination sourcing means the buyer's ship-to address controls the rate, not your fulfillment center. A shipment to Birmingham should use about 10% when that city matches the address. Wholesale sales with valid resale certificates are exempt when documentation is on file — charge tax only to end consumers.
Shipping, delivery, and handling in Alabama
Alabama shipping tax rules depend on whether delivery is separately stated, who performs carriage, and whether handling is bundled with the item price. Some states tax shipping whenever the product is taxable; others exempt common carrier delivery when stated separately on the invoice. Use our shipping tax calculator with this state's combined rate as a starting point, then read AL DOR publications for the exact phrasing your invoices use.
Installation, freight on exempt equipment, and third-party pickup may be treated differently from standard UPS/FedEx charges. Document your policy in checkout terms. On refunds, reverse tax on shipping only if the original shipping charge was taxable — audit worksheets should show the same base as the original sale.
Filing frequency, records, and common audit issues
Registered Alabama sellers file on a schedule tied to volume — often monthly or quarterly. Returns summarize taxable gross, exempt sales, tax collected, and vendor compensation credits if applicable. Late payments accrue interest; repeated under-collection triggers assessment plus penalty.
Auditors compare address samples to applied rates, review exemption certificates for expiration, and test whether shipping was taxed consistently. Keep rate tables, contract quotes, and calculator snapshots with each major rate change.
