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.

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. Nebraska Contractor Registration + City of Omaha HVAC (ACAD) License

   Nebraska has no statewide HVAC or mechanical contractor license.

Omaha's journeyman and master licenses are valid up to two years, expiring December 31 of odd years; apprentice licenses expire every December 31. EPA Section 608 certification is a federal requirement for refrigerant handling, and a city mechanical permit is required for each installation or major repair.

2. City of Omaha Business Licensing (no general business license)

   Omaha does not require a general business license. The city's Finance Department administers occupation taxes only on specific categories (restaurant/bar, telephone, hotel/motel, tobacco), and there is no City Clerk business license for ordinary businesses. Most trades on this list — food truck, handyman, tattoo parlor, personal trainer, HVAC, pet sitting, real estate, cleaning, grooming, salons, electrical, plumbing, fitness, massage, home bakery, pest control, auto repair, catering, notary, photography, barber, landscaping, tutoring, yoga, wedding planning, pressure washing, daycare, insurance — instead need a category-specific approval: a Douglas County Health Department food permit, a state professional license, Nebraska Department of Labor contractor registration, or a city building/trade permit.
