Boone County, Missouri Business License (Columbia Area)

Boone County businesses need a merchant license from the County Collector to operate legally. It costs $25 per year and covers retail or wholesale activity within the county, whether you're inside Columbia city limits or in unincorporated Boone County. This guide walks through what you need, when you need it, and how long it takes.

What You Actually Need (The Short Version)

If you're selling tangible goods or taxable services at retail or wholesale in Boone County, you need all three of these:

1. A Missouri sales tax permit (state requirement, no cost)
2. A Boone County merchant license (County Collector, $25/year)
3. A Columbia city business license (if you operate inside the city limits)

You do NOT need a statewide Missouri business license. Missouri has no general statewide business license requirement. The state only requires a sales tax permit if you sell taxable goods or services.

The Boone County Merchant License (Your Local License)

The Boone County Collector issues the merchant license. This is the license locals call "the business license," and it's what you hang on your wall.

Who Must Get One

You need a Boone County merchant license if you have a Missouri sales tax number and operate a retail or wholesale business inside or outside city limits. The license requirement follows your sales tax status, not your location.

A few businesses are exempt:

• Physicians, dentists, and veterinarians selling goods in the course of their practice
• Farmers selling directly from their farm location (no separate storefront or business location)

If you operate a service business with no taxable sales (consulting, accounting, photography), you may not need the merchant license. Call the Boone County Collector's office to confirm your type of business.

Cost and Calendar Year

The merchant license costs $25 per year. It runs on the calendar year (January 1 through December 31). If you start mid-year, ask the Collector whether any proration applies; the license still expires December 31.

How to Apply

Apply by mail or in person at the Boone County Collector's office; you can also call the office to have an application sent. Bring your Missouri sales tax number (you'll get this from the state first, see below). The Collector will issue your license the same day in most cases.

The Boone County Collector's office is in the Boone County Government Center, 801 E. Walnut St., Room 118, Columbia. Call (573) 886-4285 to confirm current hours.

Missouri Sales Tax Permit (State Requirement, First Step)

Before you get your Boone County merchant license, you must register with the Missouri Department of Revenue for a sales tax permit. This is a state requirement, not a county one.

Cost

There is no fee for the sales tax permit.

How to Register

Register online at the Missouri Department of Revenue website: https://dor.mo.gov/register-business/

You will need:

• Your Social Security Number or Federal Employer Identification Number (EIN)
• Your business address in Missouri
• Expected monthly sales
• Type of business

Online registration is generally faster than a paper application. Processing times vary, so register before you plan to open.

Sales Tax Rate in Boone County

Missouri's state sales tax is 4.225%. Boone County and Columbia may add local sales tax on top of this. The exact rate depends on your specific location within the county and what you sell. Check with the Boone County Collector or the City of Columbia for the total rate that applies to your business address.

Your Sales Tax Responsibility

Once you have your sales tax number, you must collect sales tax from customers and remit it to the state. The filing frequency (monthly, quarterly, or annually) depends on your sales volume. The Missouri Department of Revenue will notify you of your filing schedule.

Columbia City Business License (If You're in the City)

If your business address is within Columbia city limits, you must also get a Columbia city business license. This is separate from the Boone County merchant license.

If you're in unincorporated Boone County (outside any city), you only need the county merchant license.

How to Obtain One

Contact the City of Columbia's Finance Department or visit the city website to learn the current fee, application process, and requirements. City licenses often have their own fees and may require proof of zoning compliance or other local approvals.

Zoning and Land Use

Before you invest in a location, verify that your planned business use is allowed there. Zoning rules are different for unincorporated Boone County and the City of Columbia.

Unincorporated Boone County

Contact Boone County Resource Management (planning and zoning) to confirm your location is properly zoned for your business type. Some business types (commercial kitchens, manufacturing, storage) have strict zoning limits.

City of Columbia

Contact the City of Columbia's Community Development Department (Planning and Zoning) to confirm zoning compliance. Operating in a non-compliant zone can result in fines or an order to cease operations.

Health Permits and Food Service

If you sell food or beverages (retail or prepared), you need a food permit from the Columbia/Boone County Department of Public Health and Human Services, regardless of whether you're in the city or county.

This includes:

• Restaurants and cafes
• Bakeries and commercial kitchens
• Catering and meal prep businesses
• Food trucks and temporary food service
• Retail food establishments (some specialty foods, coffee shops)

Contact the health department early in your planning. Inspections and approval take time, and building or kitchen modifications may be required.

Timeline: What to Do First and When

Before You Sign a Lease or Buy Property

Verify zoning with the County Planning Office or City Planning and Development Services. This is free and takes one phone call.

When You're Ready to Launch (Allow 2 to 4 Weeks)

1. Register for Missouri sales tax (Day 1): Go to https://dor.mo.gov/register-business/ online. Allow time for processing before you apply for the county license.
2. Apply for Boone County merchant license (Day 2 to 5): Visit the County Collector with your sales tax number. Pay $25. License issued same day in most cases.
3. Apply for Columbia city license (if applicable, Day 2 to 10): Contact the City of Columbia. Fees and timeline vary by city requirements.
4. Apply for food license (if applicable, Day 1 to 14): Contact the Columbia/Boone County Public Health Department. Inspections may take several weeks.

You can operate legally once you have your sales tax number and Boone County merchant license. The city license should not delay you; apply for it in parallel.

Do Not Assume You're Exempt

Many new business owners think they can skip the merchant license because they're a small home-based business or they don't plan to store inventory in a physical location. This is wrong. If you have a Missouri sales tax number and you're selling at retail or wholesale, you need the $25 county merchant license.

The only exemptions are physicians, dentists, vets (for goods sold in practice), and farmers selling directly from their farm. If that isn't you, get the license.
