How to Start a Plumbing Business in Nebraska: No State License, a City or Village Master Plumber License, Omaha $100 and Lincoln $250 Contractor Fee

If you are searching for a Nebraska plumbing license, start with the fact that surprises most people: Nebraska does not issue a state plumbing license. Plumbers are licensed by the city or village nearest the job site. The State Electrical Division and DHHS do not license plumbing, so your startup steps depend on where you plan to work. This guide covers the order that works in practice: confirm the local license, form the business, meet the city's requirements, pull permits for each job, and register with the state for taxes and employees.

This article is informational content, not legal or tax advice. Fees and rules change, and the city fee pages cited below are archived, so confirm every figure with the issuing city before you spend money. For complex situations, talk with a qualified Nebraska attorney and a CPA.

What You Need Before You Start

Gather these items before you file anything. Most delays happen because an applicant discovers a missing document after paying a fee.

• A business name checked against the Nebraska Secretary of State business search. The name cannot be the same as or deceptively similar to a name already on record.
• A Nebraska registered agent. The agent must be an individual who resides in Nebraska or an entity authorized to transact business in the state, and the agent's office must match the registered office.
• Your Social Security number or federal Employer Identification Number, which most state and city applications request.
• Proof of insurance and a surety bond. Omaha requires $1,000,000 in insurance and a $10,000 bond for its master plumber license.
• Exam and continuing education records. Omaha requires an exam and 8 continuing education hours at renewal.
• Filing fees: $100 for a Certificate of Organization (LLC) or Articles of Incorporation (corporation), $30 for a 120-day name reservation if you want one, and $100 to $110 for a trade name if you operate as a sole proprietor under a name other than your own.
• A newspaper publication budget for LLCs and corporations. The newspaper sets its own price, so request quotes from legal newspapers.

Step 1: Confirm Which City or Village Licenses Your Work

Nebraska law requires anyone installing or repairing sanitary plumbing to be a master plumber licensed by the city or village nearest the construction site (Neb. Rev. Stat. 18-1917). Employees who do the work must be licensed journeymen in that same city or village. Nebraska has 528 municipalities (cities and villages), so the licensing answer depends on the address of each job, not on where your office or truck is based.

Two rules make this step non-negotiable. Skipping the local license is unlawful in any city or village that has a plumbing board, and it is also unlawful inside Omaha's extraterritorial zoning area (18-1910). If you plan to work in a suburb, a small town, or the area around a city, call that municipality's building department or city clerk and ask three questions: Does it have a plumbing board? Does it issue master plumber licenses? Which office takes the application?

Write the answers down, and keep them with your business file. A license from one city does not carry over to a job in another, so a service area that crosses city lines means more than one set of fees, forms, and renewal dates.

Step 2: Know the Fees and License Tiers

State law caps city plumbing license fees at $25 per license (Neb. Rev. Stat. 18-1911). Both cities publish higher fees, so do not budget from the $25 figure. Use the schedules below as a starting point, and confirm each amount with the issuing office before you file.

City	License	Published fee	Notes
Omaha	Master plumber, initial	$100 plus $8 tech fee	Exam, $1,000,000 insurance, $10,000 bond
Omaha	Master plumber, renewal	$75 plus $6	8 continuing education hours
Lincoln	Master contractor, yearly	$250	Insurance required; confirm the minimum with Building and Safety
Lincoln	Master	$75	Renewal window March 1 to May 31
Lincoln	Journeyman	$50	For employees doing the work
Lincoln	Apprentice	$25	Works under supervision

The Omaha figures come from the Planning Department licensing page, which is archived, so check the current amounts directly with the city. The Lincoln figures come from the Building and Safety page, also archived as of 2025. Omaha also licenses lawn sprinkler, sewer layer, and water conditioning work. If your services include any of those, ask whether each one requires its own license.

Step 3: Form the Business Entity

Nebraska offers three common structures for a plumbing business. Your choice affects personal liability, taxes, and recurring filings. Treat this section as general information, and have a CPA or attorney review your choice before you file.

Limited liability company (LLC)

File a Certificate of Organization with the Nebraska Secretary of State for $100. The name must contain the words limited liability company or limited company, or an abbreviation such as LLC, L.L.C., L.C., or LC (Neb. Rev. Stat. 21-108). If you need time to decide, a name reservation lasts 120 days and costs $30.

After filing, a new LLC must publish a notice in a legal newspaper for three successive weeks and file proof of publication with the Secretary of State. Every LLC must also maintain a Nebraska registered agent and office (21-113). Changing the agent or office costs $25 online or $30 on paper. Losing the agent can lead to administrative dissolution, so put the agent's contract renewal on your calendar.

Corporation

Nebraska issues no state form for corporations. You draft the Articles of Incorporation yourself, and the document must list a registered agent and registered office. The filing fee is $100, and the articles may be submitted through eDelivery. New corporations also publish notice in a legal newspaper for three successive weeks and file proof with the Secretary of State, the same as LLCs.

Sole proprietorship with a trade name

If you operate under your own legal name, you need no entity filing, but you also have no liability separation from the business. If you want to operate as something like Cornhusker Plumbing, you must register a trade name with the Secretary of State. The Application for Registration of Trade Name is a statewide filing, not a county filing. It costs $100 online through eDelivery or $110 in office or by mail. A separate newspaper publication is required, and the proof of publication carries no fee. A registration lasts 10 years and renews for $110.

Online filings go through the Corporate and Business Document eDelivery portal at https://www.nebraska.gov/apps-sos-edocs/. The Secretary of State does not publish a standard processing time, and its fee schedule lists no expedited service. Staff review each document before filing, so build extra time into your schedule.

Step 4: Earn the Master Plumber License

Once the entity and name are set, apply for the master plumber license in your first city. Confirm the exact requirements with that city, but expect these elements:

1. Meet the experience and exam requirements. Omaha requires an exam. Ask the city what experience it accepts, how often it offers the test, and whether you can take it before your entity filing is complete.
2. Submit proof of insurance and a bond. Omaha's master plumber license requires $1,000,000 in insurance and a $10,000 bond. Lincoln requires insurance from plumbing contractors, but the minimum must be confirmed with Building and Safety.
3. Pay the initial fee. In Omaha, the initial master plumber fee is $100 plus an $8 tech fee. In Lincoln, the yearly master contractor fee is $250.
4. License your journeymen. Anyone doing sanitary plumbing for your business must hold a journeyman license from that city. Lincoln lists journeyman at $50 and apprentice at $25.
5. Calendar renewals. Omaha's renewal is $75 plus $6 and requires 8 continuing education hours. Lincoln's renewal window runs March 1 to May 31 according to its archived page.

One exemption applies. Employees of a single employer who do not serve the public are exempt from licensing (Neb. Rev. Stat. 18-1919). That covers an in-house maintenance plumber for one company. It does not cover a technician sent to customers' homes or businesses. If your business serves the public, plan to license every person who does sanitary work.

Step 5: Pull a Permit for Each Qualifying Job

A city or village permit is required for sanitary plumbing in any building except a single-family dwelling or a farm or ranch structure (Neb. Rev. Stat. 18-1916). Work on a duplex, an apartment building, a commercial space, or any other non-exempt structure needs a permit. Doing the work without one carries a fine of $50 to $500 (18-1918).

Build permit fees and inspection timing into your bids. Ask the city whether the licensed master plumber, the property owner, or both must pull the permit, and whether an inspection must happen before the work is covered. The permit and inspection rules are local, so the city's building office is the final source on any specific job.

Step 6: Register With the State for Taxes and Employees

Nebraska has no general state business license and no county business license. Registrations follow your activity, and each one comes from a different office.

• Department of Revenue: Register for a Nebraska sales and use tax permit if you make retail sales, rent or lease tangible personal property, or provide taxable services. Ask the Department whether your plumbing services, and any materials you sell to customers, are taxable. The state sales tax rate is 5.5%. Register online at the Department of Revenue new business portal. If you will have employees, you also need an income tax withholding certificate.
• Department of Labor: Confirm your unemployment tax registration and whether you must register as a contractor. Ask before you make your first hire, because the requirement applies to the business, not just to a specific job.
• Secretary of State: Handle the entity filings and the recurring reports described in Step 7.
• City: Cities can levy their own sales taxes and occupation taxes. Ask the city clerk what applies to your business. Also check city and county zoning before you store vans, parts, or equipment at a home or leased yard.

Your entity choice also drives income tax. An LLC treated as a pass-through reports its income on the members' Nebraska individual returns, at 2026 rates of 2.46% to 4.55%. An LLC taxed as a corporation pays the 4.55% Nebraska corporate income tax for tax years beginning on or after January 1, 2026. Nebraska imposes no franchise tax and no occupation tax on LLCs. The Department of Revenue at revenue.nebraska.gov is the authority for how these rules apply to your facts.

Step 7: Calendar the Recurring Filings

Missed filings are the most common way a licensed business falls out of good standing. Put each date on your calendar as soon as you form the entity.

Filing	Who files	Due	Fee
Biennial report	LLCs	Odd-numbered years, January 1 to April 1; delinquent after June 16	$25 online or $30 on paper
Biennial report and occupation tax	Corporations	March 1 of even-numbered years; delinquent after April 15	$26 minimum
Trade name renewal	Sole proprietors using a trade name	Before the 10-year registration ends	$110
Master plumber renewal	Each city license	Per the issuing city's schedule	Omaha $75 plus $6; Lincoln renewal March 1 to May 31

The $26 corporate figure is the statutory minimum occupation tax, charged when paid-up capital stock does not exceed $10,000. The tax rises with paid-up capital stock under Neb. Rev. Stat. 21-303. The LLC biennial report is the only recurring Secretary of State charge for an LLC, but missing it is serious. An LLC that is delinquent after June 16 of an odd-numbered year faces administrative dissolution.

Common Mistakes to Avoid

• Assuming a state plumbing license exists. Nebraska has none, so a state card will not satisfy a city inspector or a city license office.
• Budgeting from the $25 state cap. The cap is in state law, but both cities publish higher fees, and those are the amounts you will pay.
• Working in a new city without checking its license. Each municipality licenses plumbing at the local level, so a service area that crosses city lines needs research for each city.
• Letting unlicensed helpers do sanitary work for the public. Employees must be licensed journeymen unless the single-employer exemption applies.
• Skipping the permit on a non-exempt building. Single-family dwellings and farm or ranch structures are the only listed exceptions, so confirm before you assume a job is exempt.
• Treating the filing as the finish line. New LLCs and corporations must still publish notice for three successive weeks and file proof with the Secretary of State.
• Losing the registered agent. Changing or losing the agent can lead to administrative dissolution, and a change costs $25 online or $30 on paper.
• Operating under a business name without a trade name registration. A sole proprietor who uses a name other than their own needs to register it.

Tips for a Smoother Start

• Call the city before you buy insurance. Insurance and bond requirements differ by city, and you should have the exact minimum in writing before you shop for a policy.
• Ask for written fee schedules. Archived web pages can be out of date, so request the current schedule from each city office and keep a copy in your file.
• Use free start-up help. The Nebraska Business Development Center at the University of Nebraska at Omaha offers start-up and growth resources at the Nebraska Business Development Center site.
• Check federal small business resources. The SBA has a Nebraska district page at sba.gov/district/nebraska that can help you find local counseling and financing information.
• Keep a single compliance calendar. Combine the state filings, city renewals, insurance expiration dates, and trade name deadlines in one place.

What Results to Expect

Following these steps may get your plumbing business to a legal, insured, and permitted starting point. Timing depends on the city's exam schedule, the Secretary of State's review of your filings, your insurer's underwriting, and how quickly the newspaper publishes your notice. Many new plumbers find the paperwork takes longer than they planned, so it is reasonable to allow several weeks before your first sanitary job.

A properly licensed, insured, and permitted business may find it easier to earn commercial bids and satisfy inspectors. No filing guarantees work, customers, or income, and results vary with your market, your skills, and your local competition.

Quick Answers

Do I need a Nebraska state plumbing license?

No. Nebraska does not issue one. You need a master plumber license from the city or village nearest each job, and your journeymen need journeyman licenses from that same city or village.

How do I become a plumber in Nebraska?

Work toward a master plumber license in your city, pass the local exam if the city requires one, insure and bond the business, pull permits for non-exempt work, and hire licensed journeymen for sanitary jobs.

What does a plumbing license cost in Omaha and Lincoln?

Omaha lists $100 plus an $8 tech fee for an initial master plumber license. Lincoln lists $250 for a yearly master contractor license. Confirm both figures with the issuing city before you file.

Do I need a plumbing license ne if I work only in a small town?

Possibly. Licensing follows the city or village nearest the job, and the municipality decides whether it has a plumbing board. Call the town office to confirm before you bid the work.

Final Notes

Nebraska plumbing licensing is local, layered, and detail-driven, so the safest approach is to verify each step with the city, the Secretary of State, and the Department of Revenue before you commit money.
