Alabama LLC taxes come in several layers: an annual Business Privilege Tax based on the company’s net worth, Alabama income tax on each member’s share of profits, federal income tax and self-employment tax on those same profits, and — depending on what the business does — sales tax, payroll taxes, and municipal license taxes. The Business Privilege Tax is the one most new owners miss, because it applies even in a year the LLC earned nothing.
Alabama Business Privilege Tax
The Business Privilege Tax is Alabama’s annual charge for the right to operate in the state. It applies to every LLC registered or doing business in Alabama, whether or not the business turned a profit.1Alabama Legislature. Alabama Code 40-14A-22 – Levy and Amount of Tax It is separate from income tax; treat it as the cost of keeping your LLC in good standing.
How the Tax Is Calculated
The base is your LLC’s net worth apportioned to Alabama. The Alabama Department of Revenue states the formula as net worth plus additions, minus exclusions, multiplied by the apportionment factor, minus deductions, which produces taxable net worth.2Alabama Department of Revenue. Business Privilege Tax For an LLC that operates entirely within Alabama, the apportionment factor is essentially 100%, so taxable net worth will track your balance sheet equity closely.
The rate per $1,000 of taxable net worth is set by your LLC’s taxable income, not its net worth. A low-income LLC pays a lower rate even if it holds significant assets.
- Less than $1 in taxable income: $0.25 per $1,000 of net worth
- $1 to $199,999: $1.00 per $1,000
- $200,000 to $499,999: $1.25 per $1,000
- $500,000 to $2,499,999: $1.50 per $1,000
- $2,500,000 or more: $1.75 per $1,000
The total is capped at $15,000 per year for most LLCs. LLCs whose calculated tax comes to $100 or less are fully exempt and don’t need to file the return at all. That exemption took effect for tax years beginning after December 31, 2023.1Alabama Legislature. Alabama Code 40-14A-22 – Levy and Amount of Tax
Filing Deadlines
A new Alabama LLC must file an Initial Business Privilege Tax Return (Form BPT-IN) within two and a half months of the formation date. For a foreign LLC registering to do business in Alabama, the clock starts when it qualifies with the Secretary of State.3Alabama Department of Revenue. What Is an Initial Return? When Is It Due?
After year one, the annual return (Form PPT for pass-through entities) is due on the same date as the LLC’s corresponding federal income tax return.4Alabama Department of Revenue. Alabama Business Privilege Tax and Corporate Share Tax For a calendar-year LLC taxed as a partnership, that is March 15. Missing the deadline can trigger penalties and cost the LLC its good standing.
Federal Income Tax and Alabama’s Classification Follow
The IRS treats a single-member LLC as a disregarded entity, so the owner reports business income and expenses directly on their personal federal return. A multi-member LLC is treated as a partnership and files Form 1065, an informational return, with a Schedule K-1 to each member showing their share of income, deductions, and credits.5Internal Revenue Service. LLC Filing as a Corporation or Partnership The LLC itself pays no federal income tax under either default; profits pass through to the owners.6Internal Revenue Service. Partnerships
Alabama follows the federal classification. If the IRS treats your LLC as a partnership, Alabama does too. If you elect S-corporation or C-corporation treatment federally by filing Form 8832 or Form 2553, Alabama honors that election for state purposes as well. The classification drives which Alabama returns you file and how the income is taxed.
Self-Employment Tax
This one catches many first-time LLC owners. Because members aren’t W-2 employees, no Social Security or Medicare tax is withheld from a paycheck. Members instead owe self-employment tax on their share of the LLC’s net earnings, at a combined 15.3% — 12.4% Social Security and 2.9% Medicare.7Internal Revenue Service. Self-Employment Tax (Social Security and Medicare Taxes)
The Social Security portion applies only to the first $184,500 of net earnings in 2026.8Social Security Administration. Contribution and Benefit Base The Medicare portion has no cap, and an additional 0.9% Medicare tax kicks in on earnings above $200,000 for single filers or $250,000 for married filing jointly. You owe self-employment tax once net self-employment income reaches $400 for the year.
Members who elect S-corporation tax treatment can reduce self-employment exposure by paying themselves a reasonable salary (subject to payroll taxes) and taking the remaining profit as distributions (not subject to self-employment tax). The election creates additional payroll compliance, but for profitable LLCs the savings can be substantial.
Alabama Income Tax on Member Shares
Under the default pass-through structure, the LLC itself owes no Alabama income tax. Each member reports their share of the LLC’s income, losses, and deductions on Form 40. Alabama uses three brackets, topping out at 5%:9Alabama Department of Revenue. Individual Income Tax
- 2% on the first $500 of taxable income ($1,000 for married filing jointly)
- 4% on the next $2,500 ($5,000 for married filing jointly)
- 5% on everything above $3,000 ($6,000 for married filing jointly)
Because the 5% bracket starts at $3,000 for most filers, nearly all LLC income effectively lands at 5%.
Nonresident Members
When an LLC has members who live outside Alabama, the LLC must file a composite return and pay 5% on each nonresident member’s share of Alabama-sourced income. The requirement comes from Alabama Code § 40-18-24.2. A nonresident member can still file a personal Alabama return to claim deductions or credits, and may receive a refund if actual liability comes in below the composite payment.10Alabama Department of Revenue. Electing Pass-Through Entities
Pass-Through Entity Tax Election
Alabama lets LLCs taxed as partnerships or S-corporations elect to pay income tax at the entity level instead of passing it through. The rate is 5% of Alabama-source income, and each member receives a refundable credit on their personal return for their share of what the LLC paid.10Alabama Department of Revenue. Electing Pass-Through Entities
The reason to volunteer for entity-level tax is the federal $10,000 cap on state and local tax (SALT) deductions. When a member pays Alabama income tax personally, the deduction is capped at $10,000. When the LLC pays at the entity level, the tax is a business expense outside the SALT cap. For members in higher brackets the math often favors electing in. Electing LLCs must make quarterly estimated payments to avoid penalties and interest.
Estimated Tax Payments
LLC income isn’t subject to withholding, so members generally need to make quarterly estimated payments to both the IRS and the Alabama Department of Revenue. Waiting for the annual return can result in underpayment penalties from both.
Federal estimated payments for the 2026 tax year are due April 15, June 15, September 15, and January 15, 2027.11Taxpayer Advocate Service. Making Estimated Payments Alabama’s schedule tracks its own filing deadlines on a similar quarterly rhythm. The safe approach is to estimate annual liability, divide by four, and pay each quarter.
Sales and Use Tax
Any Alabama LLC selling tangible goods or certain taxable services must get a sales tax license from the Alabama Department of Revenue before its first taxable sale. Once licensed, the LLC collects tax from customers and remits it to the state and local jurisdictions.
State and Local Rates
Alabama’s general state sales tax rate is 4% on most retail sales of tangible personal property.12Alabama Legislature. Alabama Code 40-23-2 – Levy of Tax Some categories carry lower rates: automotive vehicles at 2%, manufacturing machinery at 1.5%, and groceries at 2% as of September 1, 2025.13Alabama Department of Revenue. Tax Rates
Counties and municipalities add their own sales taxes on top of the state rate. Local rates vary widely, and combined state-plus-local rates exceed 10% in some areas. The LLC charges the correct combined rate based on delivery destination and remits the local portion to the appropriate jurisdiction. That patchwork makes compliance labor-intensive for businesses selling across multiple locations.
Economic Nexus for Remote Sellers
An LLC selling into Alabama from another state without physical presence crosses Alabama’s economic nexus threshold at $250,000 in annual sales. Once across that line, you must register, collect, and remit Alabama sales tax as if you had a storefront in the state. Track your Alabama-destined sales through the year so you don’t discover the obligation months late.
Payroll Taxes for LLCs With Employees
Hiring employees creates two state-level payroll obligations on top of the federal payroll taxes.
State Income Tax Withholding
The LLC must withhold Alabama income tax from every employee’s wages and remit it to the Alabama Department of Revenue. Alabama uses the same three-bracket structure as its individual income tax. For an employee claiming “single with zero exemptions,” the rates are 2% on the first $500 of taxable wages, 4% on the next $2,500, and 5% above $3,000.14Alabama Administrative Code. Alabama Administrative Code 810-3-71-.02 – Computing Tax Withheld Brackets differ for employees who claim married or head-of-family status.
State Unemployment Insurance
Every LLC with employees registers with the Alabama Department of Labor for State Unemployment Insurance. The tax applies to the first $8,000 paid to each employee during the calendar year.15Alabama Department of Revenue. Unemployment Compensation Tax New employers are typically assigned a standard rate (commonly 2.7%) until they build enough payroll history to receive an experience-based rate, which can rise or fall depending on how many former employees have filed unemployment claims.
Municipal Business Licenses
Alabama municipalities have broad authority to require business licenses and levy license taxes on any trade or occupation conducted within their borders.16Alabama Legislature. Alabama Code 11-51-90 – Powers of Municipalities The amount varies enormously: some cities charge a flat annual fee, others calculate the license tax as a percentage of gross receipts. If your LLC operates in more than one municipality, you may need a separate license in each.
These licenses are easy to overlook because they come from the city, not the state. Contact the business licensing office in every municipality where your LLC has a physical location or conducts business to confirm what you owe.
Beneficial Ownership Reporting
One item to cross off the list: the federal Corporate Transparency Act originally required most LLCs to file a Beneficial Ownership Information (BOI) report with FinCEN, but an interim final rule published in March 2025 exempted all entities created in the United States. Only companies formed under foreign law and registered to do business in a U.S. state still have to file.17FinCEN.gov.
