What business license your LLC actually needs

Your LLC is formed. You’ve got your EIN. Now what? You probably need a business license. Most businesses do, unlike the certificate of good standing but the exact requirements depend on where you operate and what you do [citation:3].

Business license research means tracking down every federal, state, and local license, permit, and tax registration your specific business needs [citation:1]. It’s tedious. It’s confusing. And you can’t skip it.

What is business license research?

We’ve all been there: trying to figure out which licenses you actually need feels like digging through thousands of jurisdictions and license types. And honestly, it kind of is. Across the U.S., you’ve got thousands of local, state, and federal authorities, and every single one has its own set of rules [citation:1].

Here's the thing: forming a LLC doesn't give you the green light to operate. It just sets up the legal entity. The license is what actually lets you do business in a specific spot. A lot of folks think LLC formation covers licensing. It doesn't [citation:11].

You might need licenses at all three government levels [citation:11]:

• Federal – for regulated industries like alcohol, firearms, or aviation
• State – professional licenses, sales tax permits, and industry-specific permits
• Local – general business licenses, zoning permits, health permits, and signage approvals

For example, a restaurant in Atlanta needs a federal EIN, a state alcohol license, a state tax ID, a city health permit, and a basic city business license [citation:11]. Same business, five different licenses, three levels of government. Fun stuff.

Why it matters

Skipping license research is a gamble. The stakes are real. Here's what can happen [citation:1]:

• Fines and penalties. The city of Independence, MO, went door-to-door collecting unpaid license fees from 9,000 businesses.
• Business closures. Some cities can shut you down until violations are cleared.
• Criminal penalties. In California, unlicensed contractors can get up to six months in jail for a first offense.
• Big fines. New York hit an insurance company with a $3 million penalty for running without a license.

Licensing authorities aren’t just being difficult. They’re enforcing rules that protect consumers and keep competition fair. A business that runs without the right licenses is cutting corners, and the government usually catches on eventually.

I've talked to founders who thought they were fine because they filed their LLC. Then they tried to open a business bank account or sign a lease, and the bank or landlord asked for their business license. Awkward conversation [citation:2].

Common licenses and permits

Here's what you might need, depending on your business:

Notice the pattern. A coffee shop in New York City needs a totally different mix of licenses than a consulting firm out in rural Wyoming [citation:3]. A generic list won't tell you what your business actually needs. So yeah, that's why you've gotta do the research.

How to research your licenses

You have a few options. None are perfect, but here's how to tackle it.

Option 1: Do it yourself. It’s the cheapest route, but it’ll eat your time. Start with your city’s business portal. Then hit up your county. Then your state’s revenue or licensing folks. And if you’re in a regulated field, throw federal agencies in too. The catch? There are over 19,000 separate licensing jurisdictions in the U.S. [citation:11]. Good luck.

Option 2: Use a license research service. Services like ZenBusiness give you a Business License Report that spells out every license, permit, and tax registration you’ll need, based on your exact address and what you’re doing [citation:3]. Wolters Kluwer’s BizFilings does the same thing for $149 a location [citation:11]. And LegalZoom rolled out an AI powered license research tool in 2026 that handles a lot of the legwork for you [citation:5].

Option 3: Pay for full filing service. Some services won't just research your licenses. They'll also fill out and submit every application for you. ZenBusiness does this through its "Business License Filing" [citation:3].

A few things to watch for:

• Government application fees are separate from the service fee. You'll pay those directly to the agencies.
• If you change your business address or name, you might need brand new licenses. Some states even require a fresh one just for moving [citation:1].
• If you operate in multiple locations, you might need licenses in each city or county.

License research services

Here's how the big names line up:

Which one should you go with? If you're a solo founder running something simple, like consulting, freelancing, or an online store, you can probably dig through the license research yourself in a few hours. But if you're opening a physical spot or working in a regulated field, shelling out for a service likely pays off. Whether LLC services are actually worth paying for fits right in here.

One more thing: license research from formation companies is usually an add-on, not part of the package. Comparing Inc Authority vs ZenBusiness shows how each handles these extras.

Costs and penalties

The cost of license research varies. Government application fees usually run from $0 to $100 per license, averaging around $25 [citation:3]. Research services, though, can cost you anywhere from $149 up to a few hundred bucks, depending on how complex things get and how much hand holding you need [citation:11].

The cost of not researching is way higher. Fines vary by jurisdiction, but we're talking hundreds to thousands of dollars per violation. Extreme cases? Businesses get shut down. How to keep your LLC compliant also covers license renewal timelines.

Licenses need renewing, too. Most cities want that done every year. States differ. If you miss a renewal, it’s like you never had the license. Some services keep track of those dates for you. Certificate of Good Standing usually demands current licenses.

If you're still planning things out, set aside money for licensing. You’ll need to cover application fees and maybe some service fees too. It’s not the most exciting cost, but it’s one of the few that can actually stop you cold if you ignore it.
