How to Get a Business License in Idaho (2026)

State registration, entity filings, and assumed business names

Idaho Secretary of State filings

If you form an LLC, corporation, or other registered entity in Idaho, you file with the Idaho Secretary of State. Idaho’s online filing portal is SOSBiz.

Idaho’s business portal says business names and entity types should be registered before you start doing business. It also says business registrations are public records, so home-based owners should understand that address information on filings may become public.

Assumed Business Name, also called DBA

Idaho uses the term Assumed Business Name. Many people call this a DBA.

A sole proprietor or partnership may need an Assumed Business Name when using a business name that is not the owner’s full legal name. Idaho says sole proprietors who use their full first and last name as part of the business name may be able to operate without registering an assumed name, but those using only a first or last name must register.

An Assumed Business Name is not the same as an LLC, corporation, tax permit, or local license. Idaho’s official page says registering only a business name does not create a legal business entity, does not provide liability protection, and is not a business license.

Name checks are not the same as trademark clearance

Before filing, search Idaho business names through SOSBiz. Also check for confusingly similar names. If the name matters to your brand, consider checking federal and Idaho trademark records. A state name filing does not guarantee that a name is safe to use in every legal or branding situation.

Idaho seller’s permits and tax accounts

Idaho does not use the phrase “seller’s permit” as a general business license. It is a sales and use tax permit handled by the Idaho State Tax Commission.

When a seller’s permit may be needed

The Idaho State Tax Commission says almost every seller in Idaho needs a seller’s permit if the seller makes more than two sales during a 12-month period, publicly makes it known that they sell taxable products or services, sells to a final consumer, meets Idaho nexus rules, or has others selling, delivering, installing, or taking orders for goods in Idaho.

If you need a regular seller’s permit, the Tax Commission says you should register your business with the State of Idaho before applying and display the permit in a visible place at your business.

Temporary seller’s permits

Idaho also has temporary seller’s permits for infrequent retail sales. The Tax Commission gives examples such as farmers markets, craft fairs, fireworks stands, Christmas tree stands, and occasional home sales. Some temporary permits are for one specific event. Others can cover Idaho events and the seller’s own sales activities up to the end of the calendar year.

You cannot use a temporary seller’s permit for every business. Idaho says sellers who sell, lease, or rent vehicles, or who rent short-term lodging, generally need a regular seller’s permit unless a short-term rental marketplace collects and sends in all taxes due for the lodging sales.

Idaho small seller exemption

Idaho’s small seller exemption took effect July 1, 2025. The Tax Commission says it may apply to an Idaho resident operating as an individual or sole proprietorship whose gross sales are $5,000 or less in both the current and previous calendar years, and who meets the other requirements.

This exemption does not apply to every sale. Idaho lists exclusions, including motor vehicles, trailers, lodging, alcohol or tobacco products, and admissions or entertainment. Small sellers also have recordkeeping and income reporting responsibilities.

Marketplace and short-term rental platform sales

Marketplace collection can change the tax permit answer, but it does not answer every licensing question. Idaho says a seller may not need a seller’s permit when selling only on third-party marketplaces that register with the Tax Commission, collect Idaho sales tax, and send it in for the seller. The seller still needs to verify that the marketplace is reporting the sales.

Short-term lodging is different. If you rent only through a short-term rental marketplace that collects and sends in all taxes due for all your sales, you may not need certain lodging tax permits. If you rent through your own website, phone, email, direct booking, or charge fees the marketplace does not collect tax on, you may need Idaho lodging-related tax permits. Local zoning and short-term rental rules may still apply.

Employer setup in Idaho

If you hire workers, check federal and Idaho employer rules before the first employee starts work.

Federal EIN

The IRS says businesses generally need an Employer Identification Number if they hire employees, operate as a partnership or corporation, pay certain federal taxes, or meet other IRS rules. Apply directly through the IRS EIN page.

Idaho Business Registration for employer accounts

The Idaho State Tax Commission says Idaho Business Registration is used for certain tax permits. If you have employees, you may also receive an income tax withholding account and employer-related accounts from the Idaho Department of Labor and Idaho Industrial Commission.

The Idaho Department of Labor uses its Employer Portal for unemployment insurance tax account management. Employers can also use Idaho Department of Labor tools for unemployment tax reporting and new hire reporting.

Workers’ compensation

The Idaho Industrial Commission says employers with one or more full-time, part-time, seasonal, or occasional employees must maintain a workers’ compensation policy unless specifically exempt. It also says coverage must be in place before the first employee is hired.

New hire reporting

Idaho employers must report new employees to the Idaho Department of Labor within 20 days of the date of hire. This also applies to rehired employees if their previous employment ended at least 60 days before their first day back.

Industry-specific licenses and permits

Some Idaho businesses need special state, local, or federal approvals because of what they do. Use Idaho’s Business Wizard and the agency directory below as a starting point.

Home-based businesses in Idaho

Idaho’s state registration rules can still apply to home-based businesses. Idaho’s business portal says all businesses, including home-based ones, need to register their name and entity type before doing business unless the sole proprietor full-name exception applies.

Local rules are often the bigger issue. Your city or county may require a home occupation permit, zoning clearance, limits on employees or customer visits, parking rules, sign limits, fire review, or a separate permit for food, childcare, short-term rental, salon, repair, or storage activities.

Before opening from home, contact the city clerk or planning office if you are inside city limits. If you are outside city limits, contact the county clerk, recorder, or planning and zoning office.

City and county business licenses in Idaho

Idaho’s business portal says business licenses are issued by local city clerk offices, and many cities do not require them. It also says city clerks may issue permits for home-based businesses, conditional use permits, occupancy permits, and some local occupational licenses.

If your city is not incorporated or does not have a city clerk, Idaho’s city clerk directory says to contact the county clerk or recorder’s office.

What local offices may check

• Whether your business activity needs a local business license or permit.
• Whether your address is zoned for that use.
• Whether a home occupation permit is needed.
• Whether a certificate of occupancy, building permit, fire review, or sign approval is needed.
• Whether food, vending, alcohol, massage, security, taxi, tree trimming, soliciting, or special event rules apply.
• Whether county rules apply if you operate outside city limits.

Step-by-step Idaho business license checklist

1. Write down your exact business activity. Include whether you sell goods, provide services, prepare food, work on real property, rent lodging, sell alcohol, operate from home, travel to customers, or use online marketplaces.
2. Choose your legal structure. Decide whether you are a sole proprietor, partnership, LLC, corporation, nonprofit, or another structure. Get legal or tax advice if ownership, liability, or tax treatment is unclear.
3. Check your Idaho name filing. Use SOSBiz to search names. File the entity record or Assumed Business Name if required.
4. Apply for an EIN if needed. Use the IRS directly. Do not pay a private site unless you choose to use a paid service knowingly.
5. Check Idaho Business Registration. Use IBR if you need a seller’s permit, withholding account, unemployment insurance account, lodging-related tax permits, or related tax accounts.
6. Check the Idaho seller’s permit rules. If you sell taxable goods or services, review whether you need a regular seller’s permit, temporary seller’s permit, marketplace-only treatment, or the small seller exemption.
7. Check employer rules before hiring. Review income tax withholding, unemployment insurance, workers’ compensation, and new hire reporting.
8. Check state industry licenses. Use the Idaho Business Wizard and the relevant agency, such as DOPL, Health and Welfare, Agriculture, Environmental Quality, Transportation, State Police, Finance, or Insurance.
9. Check your exact location. Ask the city or county about business licenses, home occupation permits, zoning, occupancy, building, fire, sign, and local special permits.
10. Save proof and renewal dates. Keep copies of filings, permits, portal logins, account numbers, agency emails, approval letters, and renewal reminders.
