How to Start an S Corp in Alabama: Formation and Tax Election

An S Corporation is a tax designation, not a business entity. You form a standard corporation in Alabama first, then file a tax election with the IRS to be taxed as an S Corp. This guide walks you through both steps: the state formation process and the federal tax election that turns your corporation into an S Corp.

What Is an S Corporation?

An S Corp is not a separate legal structure you select when you file with the state. Instead, it is a tax classification chosen after you have already formed a regular C Corporation with the Alabama Secretary of State.

The key difference between a C Corp and an S Corp is how profits are taxed:

• C Corporation: The corporation pays federal income tax on profits. Shareholders then pay personal income tax on dividends received. This creates double taxation.
• S Corporation: The business itself does not pay income tax. Profits pass through to shareholders, who report their share of income on their personal tax returns. Only one layer of taxation.

An S Corp election can reduce your overall tax burden, especially if you have significant profits. However, the benefits depend on your specific situation, and you should consult a CPA or tax attorney before deciding whether an S Corp makes sense for you.

Step 1: Form a Domestic Corporation in Alabama

To become an S Corp, you must first form a standard C Corporation in Alabama. The process is straightforward:

Prepare Your Certificate of Incorporation

File a Domestic Business Corporation Certificate of Incorporation with the Alabama Secretary of State. The Secretary of State publishes the official form on its website at https://www.sos.alabama.gov/business-entities. The certificate must include:

• The corporation's legal name (must be distinguishable from existing registered names)
• The principal place of business in Alabama
• The name and street address of a registered agent in Alabama (required; cannot be a PO box)
• The county where the registered office is located
• The corporate purpose and powers
• Names and addresses of the incorporators (can be one or more people)
• Details on authorized shares and classes of stock

The registered agent must be a person or business entity with a physical street address in Alabama. Many corporations use a registered agent service, which costs between $100 to $300 per year, though you can name yourself or another person as registered agent for free.

Check Name Availability

Before filing, verify your chosen name is available by searching the Secretary of State's business name index at https://arc-sos.state.al.us/CGI/CORPNAME.MBR/INPUT. The name must contain the word "Corporation," "Incorporated," "Company," or an approved abbreviation such as "Corp." or "Inc."

File With the Alabama Secretary of State

File your Certificate of Incorporation online through the Secretary of State Online Services portal at https://www.alabamainteractive.org/sos/welcome.action or by mail to the Secretary of State's office in Montgomery. Online filing provides immediate processing; mailed filings are processed in order of receipt.

Filing fee: $200

Processing time: Online filings return a filed certificate instantly. Mailed filings are processed in order of receipt; the Secretary of State does not publish a specific turnaround window.

Once your Certificate of Incorporation is filed and accepted, your business is a legal corporation in Alabama. You can now operate as a corporation and begin the federal S election process.

Step 2: Obtain an EIN From the IRS

Your corporation must have a unique federal Employer Identification Number (EIN) before you can make an S Corp election. The EIN is a nine-digit number issued by the IRS for tax identification.

Apply for an EIN for free at the IRS website: https://www.irs.gov/ein. You can obtain an EIN online in minutes, by phone at 1-800-829-4933, by mail, or by fax. Online application is fastest.

When you apply, have your Certificate of Incorporation handy. You will need your state file number, the date of incorporation, and details about your corporation's ownership structure.

Step 3: File Form 2553 to Elect S Corporation Status

The S Corp tax election is made at the federal level by filing Form 2553 (Election by a Small Business Corporation) with the IRS. This is not an Alabama state filing; it is a federal action.

Timing and Deadlines

You can file Form 2553 in two ways:

• Timely election: File by March 15 of the tax year you want the election to take effect, or within 2 months and 15 days after you incorporated. If you miss this deadline, your S election will not take effect until the following tax year.
• Late election: If you miss the timely deadline, you can request late acceptance from the IRS, though the IRS does not always grant late elections. There may be a fee involved ($500 as of 2026, but confirm with the IRS).

Who Must Sign Form 2553

Form 2553 must be signed by each shareholder who owns stock at the time the election is effective. If you are a single-shareholder S Corp, you sign. If there are multiple shareholders, all must sign the form.

File the Form

File Form 2553 with the IRS using the mailing address on the form, or check https://www.irs.gov for current e-file options. The IRS will confirm receipt of your election, usually within a few weeks.

Once the IRS accepts your S Corp election, you are now an S Corporation for federal tax purposes. Your corporation will no longer be subject to federal corporate income tax. Instead, profits pass through to shareholders.

Alabama Taxes for S Corporations

An S Corp election affects federal taxes, not state taxes. Alabama does not recognize S Corps as a separate entity type. Your corporation remains a corporation under Alabama law and is subject to the following state taxes:

Alabama Business Privilege Tax

Every corporation in Alabama must pay the Business Privilege Tax, administered by the Alabama Department of Revenue. This is a tax on net worth, not profits. The rate runs from $0.25 to $1.75 for each $1,000 of net worth, graduated by your federal taxable income apportioned to Alabama. The maximum tax for most entities is $15,000 per year.

Important exemption: For tax years beginning after December 31, 2023, if your calculated tax is $100 or less, you are fully exempt from the Business Privilege Tax and do not file a return (Act 2022-252).

The Business Privilege Tax return (Form PPT) is due two and a half months after the beginning of your tax year, which is March 15 for calendar-year filers.

County Business License

Every corporation in Alabama must obtain a business privilege license from the probate judge or license commissioner in the county where your business operates. This is separate from state filing and costs vary by county and business type. Most licenses renew annually.

Sales Tax

If your S Corp sells taxable goods or services, register for an Alabama sales tax permit through My Alabama Taxes at https://myalabamataxes.alabama.gov. Registration is free and your account number arrives within 3 to 5 days. Alabama's state sales tax rate is 4%. Counties and municipalities may add local rates on top of this.

Costs and Timeline for Starting an S Corp in Alabama

Step	Cost	Timeline
Certificate of Incorporation (Alabama Secretary of State)	$200	Instant to online, or days by mail
EIN application (IRS)	Free	Same day if online
Form 2553 (S Corp election)	Free	A few weeks for IRS confirmation
County business license (varies by county)	$50 to $500 (typical range)	1 to 2 weeks
Registered agent service (optional)	$100 to $300 per year	N/A

Total startup cost to form an S Corp in Alabama: $250 to $700, depending on whether you hire a registered agent service and your county's business license fees.

When Should You Choose an S Corp?

An S Corp may make sense if:

• Your business generates significant annual profits (generally $50,000 or more).
• You want to reduce self-employment taxes by splitting income between wages and distributions.
• You plan to retain earnings in the business rather than distributing all profits.
• You want to pass losses through to your personal tax return.

An S Corp is typically not necessary if:

• Your business has low or minimal profit.
• You plan to distribute all profits to yourself as a sole owner.
• The complexity and ongoing compliance requirements outweigh the tax savings.

An S Corp also has ongoing compliance requirements, including regular payroll processing (you must pay yourself a reasonable W-2 wage if the business has profits), annual information returns to shareholders, and quarterly estimated tax payments. These add administrative burden that a simpler entity may not require.

Next Steps After Formation

Once your S Corp is formed and your federal tax election is accepted, you should:

• Open a business bank account in your corporation's name and EIN.
• Establish corporate bylaws and keep corporate records (meeting minutes, stock ledgers, etc.).
• Set up a payroll system and process your own W-2 wages if the business has profits.
• File your first annual information return (Form 1120-S) with the IRS by the tax deadline, typically March 15 for calendar-year corporations.
• File state Business Privilege Tax returns and any required local filings.
• Maintain compliance with Alabama corporate law, including the registered agent requirement and any registered office address changes.
