1. Nebraska Department of Revenue — Sales and Use Tax Permit

   Any business selling taxable goods or taxable services in Nebraska must hold a sales tax permit from the Nebraska Department of Revenue and collect tax at the combined state and local rate for the delivery location. Register online through the Department's business registration service or by filing paper Form 20; NebFile is the separate system used to file returns once you are registered, not the registration tool. Local city sales and use taxes are layered on top of the state rate and change by quarter, so use the Department's Sales Tax Rate Finder for the exact rate at each address rather than assuming a flat figure.

2. EPA Section 608 Technician Certification (refrigerants)

   Under federal law, technicians who maintain, service, repair or dispose of equipment containing regulated refrigerants — and anyone who purchases those refrigerants — must hold EPA Section 608 technician certification. This requirement applies nationwide regardless of state licensing, so it is in addition to any Nebraska or city HVAC license. There are four certification types: Type I for small appliances, Type II for high-pressure appliances, Type III for low-pressure appliances, and Universal for all three. Certification is earned by passing a closed-book proctored exam administered by an EPA-approved certifying organization, not by the EPA itself, and does not expire. If you lose your card, the certifying organization that issued it can replace it.

   Not set by the EPA — each EPA-approved certifying organization sets its own course and proctored exam price, so this is a private-market cost rather than a government fee. Compare providers before booking.·Exams are offered on demand by approved certifying organizations, and certification does not expire once earned. The EPA publishes no processing time because it does not administer the exam.

1. HVAC Licensing for Lincoln — local trade license plus EPA Section 608

   Nebraska has no statewide HVAC or mechanical contractor license and no state mechanical contractor board. In Lincoln, HVAC contractors are licensed by Building & Safety within Planning and Development Services, which administers the trade examinations and sets the insurance requirements. Contractors must carry general liability insurance of at least $500,000 each occurrence naming the City of Lincoln as an additional insured, with the master's name listed on the certificate of insurance (a standard ACORD form is accepted, emailed to [email protected]). A bond is required only for excavation, sign and street use permits, not for ordinary HVAC work. Two other requirements apply statewide: federal EPA Section 608 certification for anyone handling refrigerants, and registration with the Nebraska Department of Labor under the Contractor Registration Act, which applies to any contractor or subcontractor doing business in Nebraska.

2. City of Lincoln Occupation Taxes (no general business license)

   Lincoln has no "Revenue Division" and issues no general city business license that must be renewed annually and displayed. The City Treasurer, within the Finance Department, administers occupation taxes on a closed list of business categories only: car rental (4%), hotel/motel (4%), restaurant and bar (2%), short-term rental (4%), telecommunications (4%), and two Enhanced Employment Area districts (Gateway-Shops at Lincoln 0.5%, SouthPointe Pavilions 1%). If your business is not in one of those categories, you owe no city occupation tax and need no city license. Regulated trades and professions are licensed by the state (for example DHHS for cosmetology, massage and body art; the Nebraska State Electrical Division for electricians) or need specific city permits such as building, electrical, plumbing and mechanical permits from Building & Safety. Confirm applicability with the City Treasurer.

3. City of Lincoln Mechanical Permit (per project)

   A mechanical permit is issued by Lincoln/Lancaster County Building & Safety (Planning and Development Services) for each HVAC installation or major repair, with inspections required on completion. Permits are filed through the joint Lincoln/Lancaster County Accela Citizen Access portal at permits.lincoln.ne.gov. Fees are itemized by equipment rather than charged as a single project price, so a typical single-unit residential job costs far less than the headline range suggests. HVAC contractors must also carry general liability insurance of at least $500,000 each occurrence naming the City of Lincoln as an additional insured, with the master's name listed on the certificate.
