Alabama's statewide rate is one of the lowest in the country, but city and county add-ons are among the highest, so the rate that actually appears on an invoice is usually more than double the state figure.
Alabama sales tax rates
Alabama charges sales tax at 4.00% statewide. Local jurisdictions add 5.46% on average and up to 8.00%, so the state rate on its own is rarely the number that belongs on an invoice.
| Statewide rate | 4.00% |
|---|---|
| Average local add-on | 5.46% |
| Highest local add-on tracked | 8.00% |
| Average combined rate | 9.46% |
| Rank by combined rate | 5th highest of 50 states |
Local rates in Alabama
Local sales tax in Alabama is set by cities, counties and in some cases special districts whose boundaries do not follow postal areas. Two customers in the same city can sit in different districts, which is why an address-based lookup beats a remembered rate.
The practical approach: look the rate up at the customer's delivery or service address using the Alabama Department of Revenue lookup, record which rate you used on the invoice, and re-check it when local taxes are renewed or introduced.
We publish the statewide rate and the state's average and maximum local add-ons here rather than a rate for every city, because city-level rates change often enough that a stale figure on this page would be worse than no figure at all.
What to put on a Alabama invoice
- The word Invoice and a unique invoice number
- Your business name, address, email and phone
- The customer's legal name and Alabama billing address
- Invoice date and a calendar due date, not just Net 30
- A line for each item or service with quantity and rate
- Any sales tax shown on its own line with the rate used
- How to pay — ACH details, check payee or a payment link
- A purchase order number where the customer issued one
- Your state tax permit number where the state expects it
- A reference to an exemption or resale certificate on exempt sales
Registering and filing in Alabama
Sellers with a physical presence in Alabama — premises, staff, stock or regular on-site work — generally register with the Alabama Department of Revenue before their first taxable sale. Remote sellers register once their sales into the state cross the state's economic nexus threshold.
Filing frequency is set by the state and usually depends on how much tax you collect: larger collectors file monthly, smaller ones quarterly or annually. The Alabama Department of Revenue sets and notifies your frequency — do not assume it stays the same as your volume grows.
We deliberately do not publish thresholds, filing deadlines or penalty amounts on this page. Those numbers change, and the only copy worth relying on is the one on the state's own site, linked below.
Exempt sales and certificates
Resale, manufacturing, non-profit and government exemptions all exist in Alabama, and each one depends on a valid certificate from the buyer, not on the buyer's word. Collect the certificate before you issue a zero-tax invoice.
Reference the certificate on the invoice rather than silently leaving tax off. A tax line of $0.00 with a note explaining why is far easier to defend in an audit than an invoice with no mention of tax at all.
Example Alabama invoice

| Description | Qty | Rate | Amount |
|---|---|---|---|
| Equipment supplied and installed | 1 | $1,600.00 | $1,600.00 |
| On-site labour | 8 | $100.00 | $800.00 |
| Subtotal | $2,400.00 | ||
| Alabama sales tax at the 9.46% average combined rate | $227.04 | ||
| Total due — Net 30 | $2,627.04 | ||
Common Alabama invoicing mistakes
Charging tax without being registered
Collecting sales tax before you are registered creates a liability with no account to remit it to, and the customer cannot reclaim it.
Assuming services are treated like goods
Taxability of services varies widely between states and within them. Confirm the treatment of your specific service with the Alabama Department of Revenue rather than copying what a supplier in another state does.
Leaving the due date implied
Write both the terms and a calendar date. In a corporate payment run, an ambiguous due date always resolves in the payer's favour.
Filing the certificate nowhere
Exemption and resale certificates are what justify a zero-tax invoice years later. Store them alongside the invoice, not in an inbox.
Sending to your day-to-day contact only
Your contact commissioned the work; a different inbox pays for it. Ask for the accounts payable address at the start.
Alabama invoicing FAQs
What is the sales tax rate in Alabama?
The statewide rate is 4.00%. Local jurisdictions add 5.46% on average and up to 8.00% where local taxes are highest, giving an average combined rate of 9.46% — the 5th highest average combined rate in the country. Figures are from the Tax Foundation's midyear 2026 table; always confirm the rate for your customer's exact address with the Alabama Department of Revenue.
Do I have to charge Alabama sales tax on my invoices?
Only if you are registered in Alabama and what you sell is taxable there. Registration is triggered by physical presence or by crossing the state's economic nexus threshold for remote sellers. Taxability of services in particular varies, so check the position for your specific work with the Alabama Department of Revenue before adding a tax line.
Does Alabama have local city or county sales taxes?
Yes. Local add-ons average 5.46% and reach 8.00% in the highest jurisdictions, so the state rate alone is rarely the rate you should show. Use the Alabama Department of Revenue address-based rate lookup for the customer's delivery address.
Is a specific invoice format required in Alabama?
There is no prescribed commercial invoice template in Alabama. What matters is that the invoice identifies both parties, describes the supply, shows the amount due, shows any sales tax separately, and can be reconciled with your returns and records.
Where do I register for Alabama sales tax?
Through the Alabama Department of Revenue, which runs registration, filing and rate lookups for Alabama. Its website is linked in the official sources section on this page.
Can I invoice a Alabama customer from another state or country?
Yes — the invoice itself is the same document. The question is whether your sales into Alabama create a registration obligation there. Remote sellers can be required to register once they exceed the state's economic nexus threshold, so track your sales by state.
