Alabama Small Business Tax Guide
Alabama income, sales and privilege taxes, quoted from ADOR and the IRS. Educational overview, not tax advice.

Tax landscape for small businesses
Alabama figures below come from the Alabama Department of Revenue (ADOR); federal figures come from the IRS. Each one sits next to its source and a date.
ADOR's individual income tax filing page (Alabama, checked October 31, 2026) says "Alabama has a graduated individual income tax, with rates ranging from 2% to 5% depending on taxable income and filing status." For sales tax, ADOR's state tax rates page (Alabama, checked October 31, 2026) lists "General: 4%" under "Sales and Use Tax Rates".
Companies that owe the Business Privilege Tax pay a rate of "$.25 to $1.75 for each $1,000 of net worth in Alabama", according to ADOR's Business Privilege Tax page (Alabama, checked October 31, 2026). The same page says "Maximum privilege tax is $15,000 for all years after 2000, unless otherwise stated."
Worked example, with sample figures: an Alabama invoice for $1,250.00 in goods, charged ADOR's "General: 4%" state rate (Alabama, checked October 31, 2026), carries a state sales tax line of $50.00 (1,250.00 x 0.04) and a total of $1,300.00. Only the state rate is shown here, and the example assumes a taxable retail sale: not an exempt item and not a sale for resale.

Filing requirements
This list isn't a complete checklist for your business.
Alabama individual income tax return
ADOR's individual income tax filing page (Alabama, checked October 31, 2026) says the return "is due on the same date as corresponding federal income returns are required to be filed, which is April 15 for most individuals." It adds "You will automatically be granted an extension until October 15." and "An extension of time granted to file is not an extension of time for payment of the tax."
Alabama estimated tax payments
The same ADOR page (Alabama, checked October 31, 2026) says "Taxpayers must make estimated income tax payments if their estimated Alabama income tax after credits and taxes withheld is expected to exceed $500." It also says "Calendar year taxpayers can pay the estimated tax in installments, on or before April 15, June 15, September 15, and January 15."
Business Privilege Tax
ADOR's Business Privilege Tax page (Alabama, checked October 31, 2026) says "For the taxable year beginning after December 31, 2022, taxpayers who would otherwise be subject to the minimum tax due of $100 shall pay $50 in lieu thereof." It names "Sections 40-14A-21 through 40-14A-29, Code of Alabama 1975." as the authority. Ask ADOR or a tax professional which return and due date apply to your entity.
Who collects Alabama sales tax
ADOR's sales tax page (Alabama, checked November 1, 2026) says "Sales tax is a privilege tax imposed on the retail sale of tangible personal property sold in Alabama by businesses located in Alabama." and "The tax is collected by the seller from their customer and remitted directly to the state." For local tax, it tells sellers to "contact all counties and municipalities in which you do business in order to determine if you should register with them to collect their local tax."
Selling into Alabama from another state
ADOR's Simplified Sellers Use Tax page (Alabama, checked November 1, 2026) describes a program that lets eligible sellers "collect, report and remit a flat 8 percent sellers use tax on all sales made into Alabama". An eligible seller sells "from an inventory or location outside the state but does not have a physical presence in the state", and sellers "must apply and be accepted into the program prior to collecting and remitting the 8 percent tax." The page also refers to "the $250,000 sales threshold for out-of-state sellers and marketplace facilitators" and says "The state of Alabama does not issue sales tax licenses (resell certificates) to remote businesses (no business locations in Alabama)." Ask ADOR or a tax professional whether your sales into Alabama mean you have to collect.
Federal estimated tax
The IRS estimated taxes page (In the US (federal), last reviewed or updated September 25, 2026) says "Individuals, including sole proprietors, partners, and S corporation shareholders, generally have to make estimated tax payments if they expect to owe tax of $1,000 or more when their return is filed."
Deductions and write-offs
Confirm with your state how it treats each item.
- Personal exemption: ADOR's individual income tax filing page (Alabama, checked October 31, 2026) lists "$1,500" for "Single" filers and "$3,000" for "Married Filing a Joint Return". The page doesn't tie these amounts to a tax year.
- Self-employment tax: the IRS self-employment tax page (In the US (federal), last reviewed or updated October 30, 2026) says "You can deduct the employer-equivalent portion of your self-employment tax in figuring your adjusted gross income."
- Records behind each deduction: the IRS recordkeeping page (In the US (federal), last reviewed or updated May 1, 2026) says "You must keep your records as long as needed to prove the income or deductions on a tax return."
Practical tips
- Untaxed purchases: ADOR's individual income tax filing page (Alabama, checked October 31, 2026) says "When you purchase merchandise for storage, use or consumption in Alabama and the retail seller does not collect tax on the purchase, you must report and pay consumer use tax on the purchase price." Keep the receipts for those purchases.
- Pay on time even with an extension. ADOR's filing page (Alabama, checked October 31, 2026) says "An extension of time granted to file is not an extension of time for payment of the tax."
- Set the tax rate once in your invoices. Billed's invoice software page (checked October 31, 2026) says "Save your tax rates and settings once, and Billed calculates taxes automatically when you create invoices and estimates."
- Keep the receipt with the cost. Billed's expense tracking page (checked October 31, 2026) says "Attach the receipt when you record the expense, and it stays with that entry in your Billed account instead of in a drawer or an inbox."
- Recheck these figures with ADOR and the IRS before you file.
