Missouri County Merchant's and Manufacturer's License: RSMo Chapter 150

If you plan to sell goods or merchandise in Missouri, one of the first requirements you may encounter is the county merchant's license. This is a local license issued by your county collector, separate from state registration. Understanding its requirements, costs, and who actually needs one can save you time and prevent compliance problems as you launch your business.

What Is the County Merchant's License?

The county merchant's and manufacturer's license is a local business license required under Missouri Revised Statutes Chapter 150 (RSMo 150). It applies to individuals and businesses that sell goods at retail or wholesale within a Missouri county. The license is issued by the county collector in each county and authorizes you to conduct your business from a specific location.

This license is required regardless of whether you operate inside or outside city limits. If you sell tangible merchandise from a Missouri location, you will almost certainly need one. The cost is modest compared to many other business licenses, but it is mandatory in most parts of the state, and operating without one can result in penalties.

Who Must Get a Merchant's License?

Missouri law requires a merchant's license for businesses that sell goods or merchandise at retail or wholesale. This includes:

• Retail stores selling clothing, groceries, books, electronics, or other tangible goods
• Wholesalers selling merchandise to other businesses
• Manufacturers operating a sales location or warehouse in Missouri
• Online retailers with a physical location or inventory in Missouri
• Temporary or mobile sellers operating at a fixed location for part of the year

Who Is Exempt?

The law exempts certain business types from the merchant's license requirement:

• Service-only businesses (plumbing, electrical, consulting, hair salons, repair shops)
• Farmers who sell only their own agricultural products or raw materials they produce
• Businesses that sell intangible products only (software licenses, subscriptions, information services)

If you operate a mixed business model (for example, a service business that also sells products), you will need a license for the goods portion of your operation.

Fee Structure: It Varies by County

One important detail: merchant's license fees are not uniform statewide. The amount depends on the county (St. Louis County's $5 fee, for example, is fixed by state law). This means the cost depends entirely on which county you operate in.

Common fee examples:

• St. Louis County: $5
• St. Charles County: $15 to $25, depending on annual sales volume
• Boone, Jefferson, Camden, and Morgan counties: $25
• Most other counties: $25 is the common fee, though some may differ

Because fees vary, you should contact your county collector directly to confirm the exact cost for your county and location. A difference of a few dollars per year may seem small, but it is worth verifying during your startup planning.

Additional Requirements Before You Apply

Many county collectors require additional steps or documentation before you can obtain a merchant's license:

• No-tax-due statement: Some counties require a letter from the Missouri Department of Revenue showing you have no outstanding tax liabilities. This can be requested through the DOR website.
• Personal property tax compliance: Several counties require proof that you have paid personal property taxes (if applicable) before issuing a new license.
• Sales tax registration: If you sell taxable goods, you must register for a sales tax license with the Missouri Department of Revenue before operating. This is a separate process from the county license.
• Local city or municipal permits: If you are inside city limits, you will usually need a city business license in addition to the county license. Check with both your county and local city.

The typical order is: register for sales tax with the state, obtain any required no-tax-due letter or personal property tax documentation, then apply for your county merchant's license.

How to Apply

Applying for a merchant's license is straightforward. Follow these steps:

1. Contact your county collector. Look up your county collector's office online or call to ask about their current merchant's license process, fees, and any required documents.
2. Complete the application. The county collector will provide a form. It typically asks for your business name, address, type of business, and estimated annual sales.
3. Provide proof of compliance. Submit any required documentation, such as a no-tax-due letter or personal property tax receipt.
4. Pay the fee. Submit the application fee. Most counties accept payment by check or cash; some accept online payment.
5. Receive your license. You will receive a license certificate or receipt to display at your business location.

Processing times are usually quick. Many county collectors can issue a license the same day or within a few business days.

Timing and Calendar Year

The merchant's license typically runs on a calendar year basis, meaning it expires on December 31 and must be renewed by January 1 of the following year. If you apply mid-year for a new business, your first license covers the remainder of that calendar year, and you renew annually thereafter.

Some counties may allow you to apply after January 1 for a pro-rated or discounted fee if you start your business later in the year. Ask your county collector about their specific renewal and pro-ration policies.

Special Cases: Jackson and Clay Counties

Jackson County and Clay County do not publish a merchant's license program under the standard RSMo 150 framework. If your business operates in these counties, contact the county collector's office to determine what local licensing, if any, applies to your specific situation.

Renewing Your License

Renewing your merchant's license is simple. The county collector typically sends a renewal notice in late fall or early winter. You pay the renewal fee, submit any updated information, and receive a new certificate for the upcoming year. Missing the renewal deadline can result in penalties or a lapse in your license, so mark your calendar and renew promptly each year.

Sales Tax Registration vs. Merchant's License

It is important to distinguish between the county merchant's license and state sales tax registration. They are separate:

• Merchant's license: Issued by the county collector. Authorizes you to operate a business in that county. Required for sellers of goods.
• Sales tax license: Obtained from the Missouri Department of Revenue. Required if you sell taxable goods. It is what allows you to collect sales tax from customers and remit it to the state.

Both are typically required for a retail business. Do not assume that obtaining one satisfies the other. Register for sales tax with the DOR, and apply for a merchant's license with your county collector.

Finding Your County Collector

To locate your county collector's office, search online for your county name plus "collector" or visit your county's official website. Most counties now have online contact information and may accept applications by mail or email. Some have begun offering online applications, but this varies by county.

Missouri has 114 counties plus the independent City of St. Louis. This guide covers the general framework and fee examples for the largest and most widely known counties. For counties not specifically mentioned here, contact your local county collector to confirm the current fee, application process, and any required documentation.

Penalties for Operating Without a License

Operating a retail or wholesale business without a valid merchant's license can result in fines and other penalties. Violating RSMo 150 can lead to prosecution and is classified as a violation of state law. It is not worth the risk. Obtain your license before you open for business.
