Post Falls Business License: General Business License Chapter, Door-to-Door Rules and Kootenai County

If you are searching for a post falls business license, start with one fact that saves time: Idaho does not have a state business license. Registering your business with the Idaho Secretary of State is a registration, not a license. Any license or permit you need in Post Falls comes from the city, from a state board that licenses a specific profession, or from the county for a specific activity such as liquor sales. Idaho counties do not issue a general business license, so your job is to work out which of these levels apply to you.

This guide covers the Post Falls General Business License chapter, the city's door-to-door rules, the state filings and what they cost, and the points where Kootenai County and state rules take over.

Disclaimer: This article is informational content, not legal or tax advice. Fees and rules change. The figures here were checked against official sources as of October 2026, but confirm each one with the agency named before you spend money or sign anything. Talk to a qualified attorney or CPA about entity choice, licensing, and tax treatment, especially if your business is complex.

What You Need Before You Start

• Your business legal name and the entity you plan to use (LLC, corporation, or a sole proprietorship)
• A physical Idaho street address for your registered agent (P.O. boxes are not accepted)
• A list of what you will sell or do, and where (a fixed location, customers' homes, online, or across the state line)
• Government-issued photo ID, which you will need in person for the city door-to-door registration
• Payment method for state and city fees (confirm accepted payment methods with each office)
• A calendar, so you can set your first annual report date the day you file

Step 1: Confirm Whether Post Falls Requires a General Business License

Post Falls City Code Title 5 includes a General Business License chapter, Chapter 5.32. The full text of that chapter and its fee could not be confirmed, so do not assume the requirement does or does not apply to you. Call Post Falls City Hall at 208-773-3511 and ask:

• Does Chapter 5.32 require a general business license for my business type and location?
• What is the current fee, and is it a one-time charge or an annual renewal?
• Where do I apply? The city routes applications through Community Development, so ask whether the form is online or must be filed in person.

Ask for the answer in writing, or ask which form and fee schedule it is based on. Idaho cities differ. Some require a general license or permit, and others license only specific activities. Post Falls is a city where you confirm rather than guess.

Step 2: Check the Door-to-Door Rules in Chapter 5.20

Post Falls regulates door-to-door sales in Chapter 5.20. The city's door-to-door registration form lists a $25 fee and requires you to present government photo ID in person. Plan for an office visit. Confirm the current form and fee with City Hall before you start knocking on doors.

Do not treat your state filing as a substitute. An LLC or an assumed business name filed with the Secretary of State is a state registration. It does not satisfy a city registration requirement.

Step 3: Form Your Entity With the Idaho Secretary of State

File through SOSBiz at sosbiz.idaho.gov/forms/business/. The core filing costs are:

• LLC: Certificate of Organization (Limited Liability Company), $100 online or $120 on paper.
• Corporation: Articles of Incorporation (General Business), $100 filing fee. Confirm the paper fee on the SOSBiz site.

Name rules. An LLC name must include "limited liability company," "limited company," "L.L.C.," "LLC," "L.C.," or "LC." "Ltd." and "Co." abbreviations are allowed. The name must be distinguishable from existing names in the SOSBiz business search. Entity-type words do not count toward distinguishability, and a name may not falsely imply government affiliation.

Name reservation. If you need time, reserve the name for 120 days for $20 at sos.idaho.gov/business-forms/.

Registered agent. Every entity must keep a registered agent in Idaho with a physical Idaho street address, available during normal business hours. The agent can be an Idaho resident, an Idaho-authorized business, or a commercial registered agent. You may act as your own agent using an Idaho address. A DBA cannot serve as a registered agent.

Processing time. Business filings are processed in about 7 to 10 days. Expedited options are a $40 surcharge for evidence of filing within 8 working hours, or a $100 surcharge for same-day service on filings submitted before 1:00 p.m. Mountain time. Check current estimates on the Processed Through Date page on SOSBiz.

Step 4: File an Assumed Business Name (DBA) if You Use One

If you operate under a name other than your registered legal name, file a Certificate of Assumed Business Name with the Idaho Secretary of State. It is filed statewide, not with Kootenai County. The fee is $25 online or $45 on paper, which includes a $20 manual data entry surcharge. An assumed business name stays active until you cancel it, and it does not renew. File at sos.idaho.gov/business-forms/.

Step 5: Check Licensing for Regulated Activities

Idaho splits licensing across several agencies, so work through each category that fits your business:

• Food businesses: Panhandle Health District oversees food businesses in this area. Ask about plan review and permits before you buy equipment or sign a lease. Confirm fees with the district.
• Liquor: Selling liquor requires a state license, a county license, and a city license. Kootenai County alcohol licensing covers the county level. Start early, because each level has its own application.
• Contractors: Idaho has no statewide general contractor license. Contractors register with the Idaho Contractors Board at DOPL.
• Other professions: Many professions have their own state board. The Business Wizard at business.idaho.gov generates a checklist of the agencies and permits a specific activity needs.

Step 6: Register for Idaho Taxes

Register with the Idaho State Tax Commission at tax.idaho.gov. If you sell taxable goods, get a sales tax permit through the Idaho Business Registration page. The state sales tax rate is 6%. Idaho has no local sales tax outside voter-approved resort cities, so most Post Falls sales carry the state rate only. Confirm the rules with the commission before you start collecting.

Income tax. Idaho's individual income tax is a flat 5.3% for 2025, so confirm the current year's rate. A default LLC is a pass-through entity, and members report Idaho income on their personal returns. An LLC that files as a partnership or S corporation owes the $10 permanent building fund tax. An LLC taxed as a C corporation pays the 5.3% business income tax plus the $10 permanent building fund tax. Idaho has no franchise tax and no LLC-specific annual state tax. A CPA can tell you which setup fits your situation.

Step 7: Know the Short-Term Rental Rule

Since July 1, 2026, under HB 583, no city or county in Idaho may require a license, fee, permit, or registration for a short-term rental. State and local lodging taxes still apply. If you rent a property short term, confirm your lodging tax obligations with the Idaho State Tax Commission and with Post Falls City Hall.

Step 8: Calendar Your Annual Report

LLCs and corporations must file an annual report every year, starting one year after formation. The report is due before the end of the month in which your formation document became effective. The fee is listed as no fee under Idaho Code 30-21-214. Set the first due date the day you file, and file through SOSBiz.

Spokane Commuter Spillover

Post Falls sits within commuting distance of Spokane, Washington, so many local businesses serve customers or hire workers who cross the state line. Idaho filings do not cover Washington. Before you take on work across the line, check with Washington state agencies about their registration and tax obligations, and confirm with Post Falls whether any Idaho city requirement applies to work you perform in Spokane.

What to Expect After You Finish

If you complete these steps, you can typically expect a filed entity in about 7 to 10 days (less with expedited service), a written answer from Post Falls about Chapter 5.32, a door-to-door registration if your work requires one, a sales tax permit if you sell taxable goods, and a calendared annual report. Timelines and fees vary, so treat these as typical outcomes, not guarantees. Keep copies of every filing, receipt, and approval.

Common Mistakes to Avoid

• Assuming your state filing is a city license. It is not.
• Taking an assumed business name to Kootenai County. DBAs are filed with the Secretary of State.
• Using a P.O. box as your registered agent address, or naming your DBA as the registered agent.
• Choosing a name without searching SOSBiz first.
• Knocking on doors before the $25 door-to-door registration is complete.
• Assuming a state liquor approval covers the county and city levels.
• Forgetting the annual report because the fee is zero.
• Paying for expedited service when your deadline does not require it.

Practical Tips

• Call Post Falls City Hall before you sign a lease or buy equipment.
• Write down the name of each person you speak with and the date of the call.
• Ask for fee and form confirmations in writing.
• Run the Business Wizard at business.idaho.gov to build your agency checklist.

A one-person service business with no alcohol, food, or contracting work may need only a few of these steps. Anything involving employees, liquor, food, contracting, or sales across state lines is worth a review with a qualified attorney and CPA before you file.
