Sole Proprietorship in Louisiana: How to Start One

A sole proprietorship is the simplest way to start a business in Louisiana. There is no formation document to file with the Louisiana Secretary of State, no annual report, and no state filing fee just to get going. You are the business, legally and financially, which makes setup fast but also means you carry unlimited personal liability for anything the business owes or gets sued over. If that tradeoff worries you, an LLC is the usual next step up in protection, but if you want to start selling a product or service under your own name this week, a sole proprietorship gets you there with the least paperwork.

This guide walks through what a Louisiana sole proprietor actually needs to do to operate legally: naming the business, registering a trade name if you need one, getting the right tax registrations, and lining up any local licenses. Every step below reflects Louisiana-specific requirements as of this writing, not generic advice.

What You'll Need Before You Start

  • A business name decision: your own legal name, or a trade name (also called a DBA, "doing business as") if you want to operate under something else
  • Access to the Secretary of State's business search at coraweb.sos.la.gov, to check that your chosen trade name isn't already taken
  • $75 if you plan to register a trade name with the Secretary of State (Form #309), or whatever fee your parish Clerk of Court charges for a local DBA filing (this varies by parish and isn't published statewide, so confirm it directly with your parish)
  • A Social Security number or federal Employer Identification Number (EIN) for tax reporting
  • Information about what you're selling, since this determines whether you need a Louisiana sales tax permit and any industry-specific license
  • Your parish and municipality, since local occupational licenses are handled at that level, not by the state

Step-by-Step: Starting a Sole Proprietorship in Louisiana

Step 1: Decide whether to operate under your own name or a trade name

If you plan to run the business under your own legal name (for example, "Jane Broussard" doing freelance photography with no separate brand name), Louisiana does not require you to register anything with the Secretary of State to form the sole proprietorship itself. You can simply start operating once you've handled the tax and license steps below.

If you want to operate under a different name, such as "Bayou Boil Catering," you need to register that name. In Louisiana this can work two ways: a trade name, trademark, or service mark registration filed with the Secretary of State, Commercial Division (Form #309, $75), or a true DBA filed with the Clerk of Court in the parish where you'll do business. The Secretary of State's office does not accept DBA filings directly; those go to the parish level. Many sole proprietors register at both the state and parish level to cover their bases, but confirm with your parish Clerk of Court what they specifically require.

Step 2: Search the name before you commit to it

Before you print business cards or build a website around a name, search it at coraweb.sos.la.gov/CommercialSearch. This search checks existing corporate, LLC, and trade names on file, including similar spellings and names that sound alike phonetically. A name that's too close to an existing registered business can get your filing rejected or expose you to a trademark dispute down the road.

Step 3: File your trade name registration, if you're using one

If you're registering with the Secretary of State, the fastest route is the geauxBIZ online portal at geauxbiz.sos.la.gov, which also generates a checklist of other licenses and permits your specific business type may need based on your industry and location. The trade name filing fee is $75. If instead (or in addition) you're filing a DBA with your parish Clerk of Court, contact that office directly for their form and fee, since this isn't standardized statewide.

Step 4: Get a federal EIN (recommended, sometimes required)

A sole proprietor with no employees can typically use a Social Security number for tax purposes and isn't required to get an EIN. That said, most banks require an EIN to open a business checking account, and using an EIN instead of your SSN on invoices and tax forms cuts down on identity theft exposure. The IRS issues EINs for free through its online application. If you plan to hire even one employee, an EIN becomes mandatory.

Step 5: Register with the Louisiana Department of Revenue for a sales tax permit, if applicable

If you'll be selling taxable goods or certain services in Louisiana, you need to register with the Louisiana Department of Revenue before you make your first sale. Registration is handled through revenue.louisiana.gov. The state sales tax rate is 5%, though most parishes and municipalities add their own local sales tax on top, so the total rate a customer pays depends on where the sale happens. As a sole proprietor, your business income also flows through to your personal return and is taxed at Louisiana's flat 3% personal income tax rate for taxable periods beginning on or after January 1, 2025.

Step 6: Check for local occupational licenses and industry permits

Louisiana does not issue one general statewide business license that covers everyone. Instead, most parishes and cities levy their own occupational license tax on businesses operating within their boundaries, and specific industries (food service, cosmetology, contracting, childcare, and others) carry their own state or local licensing requirements on top of that. Run your business type and location through the geauxBIZ checklist tool, and separately call your parish or city clerk's office to confirm their local occupational license requirements, since the state portal doesn't guarantee full local coverage.

Step 7: Set up your recordkeeping and, if needed, a registered agent

A sole proprietorship that hasn't registered a trade name with the Secretary of State generally does not need a registered agent, since that requirement applies to businesses formally registered with the Commercial Division, like LLCs and corporations. If you do register a trade name, check with the Secretary of State's office on whether an agent designation applies to your specific filing. Either way, open a separate business bank account and keep business and personal expenses apart from day one. This isn't a state filing requirement, but it's the single most common thing sole proprietors regret skipping once tax season or a dispute arrives.

Tips for a Smoother Setup

  • Check name availability before you spend money on branding. A rejected trade name filing means redoing logos, signage, and web copy.
  • Register for sales tax before your first taxable sale, not after. Retroactive registration can trigger penalties on unremitted tax.
  • Use the geauxBIZ checklist tool early, even though it won't catch every parish-level requirement, since it flags the state and federal licenses relevant to your industry.
  • Budget for both the state trade name fee and a possible separate parish DBA fee if you're using a name other than your own; treating them as one filing is a common and costly assumption.
  • Consider whether unlimited personal liability is acceptable for your business. A sole proprietorship offers no separation between your personal assets and business debts or lawsuits; an LLC (filed with Articles of Organization, Form #365, $100 filing fee) is the standard next step if that risk doesn't sit well with you.

Common Mistakes to Avoid

  • Assuming a trade name filing with the Secretary of State forms your business. It registers a name; it does not create a formal business entity or shield your personal liability the way an LLC or corporation does.
  • Skipping the parish-level DBA filing after registering a trade name with the state, or vice versa, when the parish or your bank actually requires both.
  • Operating under an unregistered name that's confusingly similar to an existing Louisiana business, which can invite a legal dispute even without a Secretary of State rejection catching it first.
  • Delaying sales tax registration until after revenue starts coming in, which can leave you owing back tax and penalties to the Department of Revenue.
  • Mixing personal and business finances from a single bank account, which makes tax time harder and weakens your recordkeeping if the IRS or the state ever asks questions.

What You Can Generally Expect

Sole proprietors who follow these steps typically find that Louisiana's process is meant to be light-touch: for many people operating under their own name with no special licensing needs, the entire setup may involve little more than a sales tax registration and a local occupational license check. Businesses that need a trade name or that operate in a regulated industry (food, health, construction, childcare) should generally expect additional time and cost for those specific filings. Processing times for state-level filings and permits can vary, so it's reasonable to confirm current timelines directly with the relevant office (Secretary of State, Department of Revenue, or your parish) rather than assume a fixed turnaround.
