What State License Do I Need to Start My Business?

By Bill Stilwell · Last reviewed October 17, 2026

The short answer

Many states require a license for certain trades and professions, such as contractors, electricians, plumbers, cosmetologists, real estate agents, and insurance agents. Rules depend on your state and your activity. The U.S. Small Business Administration (SBA) says states regulate more activities than the federal government, and suggests starting with your state’s website to find what applies. Check for a business license, the individual licenses your people need, and any registration with an industry agency.

What this means

A state license says you met the state’s standards to do certain work. It can come in a few forms.

Business or firm license. Some states license the company itself, such as a contracting company or a salon shop.

Professional and occupational licenses (9.6.1). The people doing the work often need their own license. Depending on the trade, that can include the owner, supervisors, and each worker. Some trades use a “qualifier,” a licensed person who takes responsibility for the company’s work. If that person leaves, the company may lose its license.

Industry agency registration (9.2.7). Some industries register with a state agency instead of, or on top of, a license. Examples can include contractors, home health, debt collection, and security businesses.

Other state licenses. The outline also lists sales, construction, and health licenses. A seller’s permit for collecting sales tax is covered in 10.2.2 Sales Tax. Construction rules are covered in 9.6.3 Construction Requirements. Health licenses are covered in 9.4.8 Health Requirements.

Licenses often require some mix of training, an exam, experience, insurance, a bond, and a fee. Rules and fees differ a lot from state to state.

Made-up example: Harbor Line Electric is a new two-person shop. The owner holds a master electrician license. Her helper needs his own apprentice registration. The company also needs a contractor license, which in her state requires proof of insurance and a bond. She lists all three in her requirement matrix with numbers and renewal dates.

Why it matters

Penalties. Working without a required license can bring fines and, in some states, criminal charges.
Getting paid. In some states, unlicensed contractors may not be able to enforce their contracts or collect payment.
Insurance. Insurers may deny claims for unlicensed work.
Advertising. Some boards limit how unlicensed businesses can advertise. Others require license numbers in ads (see 9.5.7 License Display Rules).
Customer trust. Many customers look up a license before they hire.

Who this applies to

Every business should check. You almost certainly need a state license if you work in construction or the skilled trades, health care, personal care, real estate, insurance, financial services, childcare, or security. Pure online businesses and many consultants may need none, but check before you assume.

How to do it

List your activities. Be specific. “Remodeling” and “electrical work” can need different licenses.
Search your state’s website. Start with your Secretary of State and your state’s professional or occupational licensing agency. Many states have a business license lookup tool or a one-stop portal.
Find the board for your trade. Read who must be licensed: the company, the owner, supervisors, or every worker.
List the requirements. Note training, exams, experience, insurance, bonds, and fees.
Apply and don’t start work until it’s issued, unless the board says in writing that you can.
Check each worker. Confirm licenses for anyone you hire, and look them up on the board’s site.
Record everything in your requirement matrix: license type, number, holder, issue date, renewal date, and continuing education due (see 9.3 Requirement Matrix and 9.5.6 License and Permit Renewals).
Show it where required and where it helps. Add your license number to your website and your credentials (see 14.1.10 Credentials and 9.5.7 License Display Rules).
Working in more than one state? Each state has its own license. Some have reciprocity agreements, but don’t assume.

What proof to keep

Each license and registration certificate
Exam results, training certificates, and continuing education records
Proof of the insurance or bond the license requires
A screenshot of each license on the state lookup site
Copies of employee licenses with their expiration dates

Common mistakes

Getting the owner licensed but not the company, or the other way around.
Losing the qualifier. If the licensed person leaves, the company license may lapse.
Hiring workers without checking their licenses.
Working outside the license class. A license for one kind of work may not cover another.
Crossing a state line for “just one job” without a license there.
Letting continuing education slide until renewal is due.

When to get help from a pro

Your state licensing board can answer most questions for free. An attorney is worth it for multi-state work, a qualifier arrangement, or a denied application. Questions to ask:

Who in my company needs a license: the business, me, or each worker?
Does my license cover every service I plan to offer?
What happens to the company license if our license holder leaves?

Bill’s note

[Bill: add a short opinion. For example, why you ask contractor clients for their license number before building their site, or a time a missing license caused trouble with a listing or a customer.]

If you’d rather have this done for you, SiteSmarty can add your license and credentials to your website and Google Business Profile.

Questions people ask

How do I find out what licenses my state requires? Start with your Secretary of State and your state’s licensing agency. Many states have a lookup tool or a one-stop business portal.

Does every worker need a license or just the owner? It depends on the trade and state. In many trades, the people doing the work need their own license.

What is a qualifying agent? A licensed person who takes responsibility for a company’s work so the company can hold a license. If they leave, the company may need a new one.

Can I work while my license is pending? Usually not. Wait until it’s issued unless the board tells you otherwise in writing.

Should I show my license number on my website? It’s good practice, and some states require it in ads. Check your board’s rules.

Audit check

Question: Does the business, and each person who needs one, hold a current state license for every regulated activity it performs?
Pass looks like: Every required business, individual, and agency license on file. Numbers and renewal dates in the matrix. Licenses match the work being done.
Fail looks like: Unlicensed work. Expired licenses. Workers never checked. License class doesn’t cover the services offered.
Evidence to collect: License certificates, state lookup screenshots, employee license copies, and the requirement matrix.
