Insurance

5How much electrical contractor insurance do you need in Missouri? What is this?

The least liability insurance Missouri lets an electrician work with is $500,000. Most customers ask for more. Workers' comp is required.

Minimum liability insurance	$500,000
Type of policy	Liability insurance, from an insurance company allowed to do business in Missouri
Who this applies to	Everyone who applies for the statewide license. Local licenses set their own amounts
Who must be named on the certificate	The rule does not name one. The certificate must come from the insurance company itself, not from your agent
City rules	Springfield asks an electrical contractor for proof of a bond, insurance, or both before it issues the business license. The city page gives no amounts
Workers' comp required?	Yes, once you have one employee, because wiring buildings is construction work
Workers' comp: what to know	Most Missouri businesses need workers' comp at five employees. Construction is the exception. If you build, alter, repair or tear down buildings, one employee is enough. A sole owner or a partner is not covered by the policy unless they ask the insurer to add them.
Workers' comp: who counts as an employee	Everyone you pay counts, whether they are part time, casual, full time or a member of your family. Members of an LLC and officers of a corporation count too. A sole owner and the partners in a partnership do not count themselves. In construction the number is one, so the count rarely matters
Workers' comp: if you skip it	Knowingly going without cover is a class A misdemeanor. You also owe the state up to three times the yearly premium you skipped, or up to $50,000, whichever is more. A second offense is a class E felony

Money checks

6Does Missouri check your credit for an electrician license? What is this?

Missouri does not check your credit for this license.

Bonds

7Does an electrician need a bond in Missouri? What is this?

Missouri does not require a state bond for this license. Some cities ask for one before they issue permits.

Does the state require a bond?	No
Amount	Not listed yet

The state itself holds no bond (a promise, backed by an insurance company, that customers can be paid if you do not finish the job). The law does say a statewide license holder must post a bond with each city or county where they work, if that place asks for one. The amount is up to the city or county.

Showing your number

8Where must a Missouri electrician show the license number? What is this?

In Missouri: put your statewide license number on every written contract. The ethics rule for license holders says so, and it also says to keep the license on hand while you work.

The rule	Put your statewide license number on every written contract. The ethics rule for license holders says so, and it also says to keep the license on hand while you work
On quotes, contracts, and invoices	On every written contract. The rule does not mention quotes or invoices
On ads	No state rule found
On your vehicles	No state rule found
If you forget	Breaking the ethics rule is grounds for discipline. The office can censure you, put you on probation for up to five years, suspend the license for up to three years, or take it away. Knowingly breaking the licensing law is a class B misdemeanor

Tax

9Does an electrician charge sales tax on labor in Missouri? What is this?

In Missouri, no sales tax. The state sales tax law lists what is taxed, and work on a building is not on the list. The rest of the rules are below.

See how this compares in every state: Can you charge sales tax on labor? The rule in 25 states

What this tax is	Missouri sales tax is a tax on goods and on a short list of services. The state treats a contractor as the final buyer of anything that ends up as part of a building
Who pays tax on materials	You. You pay sales tax at the supply house on wire, conduit, panels, breakers and fixtures you install. You do not charge the customer sales tax on them. This holds when ownership passes to the customer after you install, which is the normal case
Labor	No sales tax. The state sales tax law lists what is taxed, and work on a building is not on the list
Homes versus businesses	No difference. The rule looks at whether the materials become part of the building, not at who owns the building
New buildings	The same as repairs. You pay tax on the materials when you buy them and charge none on your bill
Selling and installing as two prices	If your contract passes ownership of an item to the customer before you install it, you are selling goods. You buy it tax-free and charge the customer sales tax on it. If you also sell fixtures from a showroom, buy stock with a resale certificate and pay the tax yourself on anything you pull for a job
Tax-exempt customers	A city, school, church or charity can give you a project exemption certificate. With it you buy the materials for that job tax-free. Tools and equipment you keep are still taxed
Tax rate	4.225 percent for the state. The sales tax law sets 4 percent and the state constitution adds 0.225 percent for conservation and for parks and soils. Cities, counties and special districts charge more on top, so check the rate for the job address

Getting paid

10Getting paid: lien and notice deadlines for a Missouri electrician What is this?

If you are not paid in Missouri, a lien on the property is your backstop, but only if your notice goes out on time: if a contractor hired you, give the owner written notice at least ten days before you file the lien (to file on September 1, deliver the notice by August 22). It must say how much you are owed and who owes it.

Who has to send a notice	Everyone, but the notice differs. If the owner hired you, you give the owner a printed warning before you are paid. If a contractor hired you, you give the owner ten days' notice before you file a lien
Written notice you must give the customer	If the owner hired you, hand over the state's Notice to Owner in 10-point bold type. It warns the owner that unpaid suppliers and workers can file a lien. Give it when the contract is signed, when materials arrive, when work starts, or with your first invoice. Skip it and you have no lien rights at all
Send your notice by	If a contractor hired you, give the owner written notice at least ten days before you file the lien (to file on September 1, deliver the notice by August 22). It must say how much you are owed and who owes it
File your lien by	File your lien statement with the circuit court clerk in the county where the property is, within six months after the debt became due (money due on March 1 means you file by September 1)
Homes the owner lives in	On repairs or remodels to a home of four units or fewer that the owner lives in, a subcontractor or supplier needs the owner's signed consent to liens. The consent is printed in the main contract in 10-point bold type. If there is no such consent and the owner has paid the contractor in full, nobody under that contractor can lien. Where the consent was signed, paying the contractor is not a defense
About home construction	On new homes built for sale, the owner can record a notice of the planned sale at least 45 days before closing. If they do, you must record a Notice of Rights with the county recorder at least five days before the closing date. Miss it and your lien rights on that property are gone
File a lawsuit by	Six months after you file the lien. If you have not sued by then, the lien ends

Watch out

12What catches people out in Missouri What is this?

The things people get wrong or do not expect about Missouri, in a few sentences.

Missouri has one statewide trade license, and it is for electrical contractors. Every city and county has to accept it, and none can make you sit its own exam on top.
The statewide license is optional. If you only work where there is no local electrical license, or you already hold the local one, the law says you do not need it.
A city that refuses a statewide license has 30 days to change its mind once the state steps in. After that the state holds back the city's local sales tax money until it does.
The $500,000 insurance proof has to come from the insurance company itself. The office will not take a certificate made out by your agent.
Renewal got cheaper on June 1, 2026. It was $200 for three years and the state cut it to $100, because the office was taking in more than it costs to run.
One fee covers three years, and every license runs out on the same day, September 30. Miss it and the license goes inactive, and you cannot work on it until you pay $250 to bring it back.
