Missouri Home-Based Business Laws: Zoning, Permits and Rules
Last verified: November 4, 2026
State law now limits what cities can demand of a home-based business (RSMo 71.990), so the first question is not "which permit do I buy" but "does my business count as no-impact." This guide covers that test, what the largest cities actually ask for, and the state registrations that apply to you wherever you live.
Our position: call your city's zoning office before you pay for anything. Fee schedules, home occupation forms and enforcement vary city by city and some cities have been revising theirs to match state law, so a figure quoted by a third-party site may already be out of date.
What State Law Says About Home Businesses
The Secretary of State says business licenses come from the local government and that its office does not issue them, and its Steps for Starting a Business tells owners to register for a business license and any other permits with their city or county, so treat a home business license as a local matter and confirm with your city or county. You can form an LLC or corporation with a home address.
The bigger rule is RSMo 71.990. In summary, as of November 3, 2026:
- Right to operate: anyone who lives in a residential dwelling may use it for a home-based business, unless a deed restriction, covenant, or an HOA or condo document says otherwise.
- No-impact businesses: a city or county may not prohibit a no-impact home-based business, and may not require you to get a permit, license, variance or other prior approval for one. Among the conditions: only lawful goods and services, no substantial increase in neighborhood traffic, activity inside the home or yard, and nothing visible from the street. Read the full statute for the complete list.
- Never required as a condition: rezoning for commercial use, a home-based business license, or fire sprinklers in a single-family or two-unit dwelling.
- Still allowed: reasonable rules narrowly tailored to public health and safety, state and federal law compliance, and tax payment. Whether a local rule fits the statute is a question for the courts.
What this means in practice: a quiet laptop business should not need a home occupation permit, but a business with customers on site, deliveries or employees can fall outside "no-impact" and back under local zoning. Cities also still require the ordinary city business license or tax registration in many cases, so the statute is a reason to ask, not a reason to skip the call. If a city insists on a permit for what looks like a no-impact business, an attorney can tell you whether the rule holds up.
Where Zoning Still Bites
Zoning is enforced by the city or county code enforcement office, usually after a neighbor complaint. The usual pressure points for a business that is not no-impact:
- Customers or clients visiting, and retail pickup
- Delivery trucks and commercial vehicle parking
- Signs, noise, odors or fumes
- Non-resident employees working on site
- Storage of hazardous materials
Businesses that tend to fit residential zoning are office-style work with no client visits: writing, design, programming, bookkeeping, remote coaching, and online sales with inventory stored at home. Food production, vehicle work, health and personal-care services, and anything that brings clients to your door are the ones cities most often limit or ban at home. Check the state licensing boards for your trade as well; a state occupational license applies at home exactly as it does anywhere else.

What the Largest Missouri Cities Ask For
These are the requirements we could confirm on official city and county pages on November 3, 2026. Fees not listed on the source were left out on purpose.
| Place | What is required | Source |
|---|---|---|
| Kansas City | Business license for every business, regardless of size. The license application requires a zoning clearance for the address. Call Planning and Development before signing a lease or applying. | KC BizCare: prepare your location |
| St. Louis (city) | Home Occupation Waiver for a business in your home (some need a Zoning Conditional Use hearing), applied for at stlcitypermits.com. Graduated business license: initial fee $25 for a home-based business versus $200 otherwise. Zoning Section: 314-622-3666. | St. Louis Business Assistance Center |
| Springfield | Home-based businesses need a business license. The application comes with a Zoning Approval and a Home Occupation Questionnaire reviewed by Building Development Services. Fee depends on activity and location. Licensing: 417-864-1617. The city's own HB 1662 presentation says the 2022 law prohibits requiring a home-based business license or other approval and that staff were revising the city code, so ask the city which process applies to you now. | Springfield Business Licensing |
| Columbia | Home occupation form with a floor plan. Up to 20% of the home and garage floor area under Sec. 29-3.3(kk), up to 40% by conditional use under Sec. 29-3.3(ll). Signs flat-mounted, one square foot, unlit; no on-site direct sales; up to 12 vehicle trips per day. No fee listed on the form. | Columbia home occupation form |
| Jefferson City | Home Occupation Permit plus Business License. Business use up to 25% of floor area or 400 square feet, whichever is less; one non-illuminated sign of one square foot; many service types excluded. Call 573-634-6410 for fees. | Jefferson City home-based businesses |
| St. Charles County (unincorporated) | Home Occupation Permit through the county portal: no more than 25% of floor area and 500 square feet; household members only; ordinary household equipment. Some retail, wholesale or manufacturing homes also need a merchant and manufacturer license. Planning and Zoning: 636-949-7335. | St. Charles County home occupation permit |
Some of these city rules were written before RSMo 71.990 and may be revised, so a permit on this list is not proof that the city can require one for your particular business. Other cities and counties follow the same pattern: look for your city's zoning code and business license office, or for unincorporated areas, the county planning office.

Step-by-Step: Checking Your Own Address
Step 1: Check Private Restrictions
Read your lease, deed restrictions and any HOA or condo documents first. The statute lets those override your right to operate.
Step 2: Ask the City or County Zoning Office
Ask whether your business is treated as no-impact and whether any permit, zoning clearance or questionnaire is still needed. Get the answer in writing or note the name and date of the call.
Step 3: Get the Local Business License if Required
Many cities license every business, home-based or not. Ask what the fee is and when it renews. Some cities also require a Statement of No Tax Due before issuing or renewing the license.
Step 4: Register for State Taxes
See the next section. This is separate from anything the city does.
Step 5: Keep Records of Your Compliance
Keep the approval, permit or written answer on file with the conditions listed on it, such as signage or employee limits.
State Tax Registration and Obligations
The Missouri Department of Revenue business registration page lets you register online for sales tax, withholding, unemployment tax and corporate income tax. DOR lists no registration fee on that page and says confirmations take 2 to 3 business days. Questions on the form: 573-751-5860 or [email protected].
Sales Tax License
If you sell tangible goods or taxable services, a business must obtain a sales tax license from DOR. The state rate is 4.225%, and cities, counties and districts can add local taxes, so use the DOR rate lookup for your address. Selling without a license carries a penalty of $500 for the first day and $100 for each later day, up to $10,000. For the full walk-through see our guide to Missouri sales tax registration.
Income Tax
A sole proprietorship or partnership reports business income on the owner's individual return. An LLC taxed as a corporation, or a corporation, pays Missouri corporate income tax at 4% of Missouri taxable income (RSMo 143.071). S-corporation treatment is a federal election. Individual rates change from year to year, so take the current rate from the DOR individual income tax page. More in Missouri income tax for business owners.
If You Hire Employees
- Withholding: register with DOR to withhold tax from wages (Section 143.191, RSMo). You also need a federal EIN, which the IRS issues free of charge.
- Unemployment insurance: register with the Division of Employment Security. New employers pay the "All Others" rate of 2.376% for 2024 through 2027 on a 2026 wage base of $9,000.
- Workers' compensation: required with five or more employees, or one or more in construction.
Choosing a Legal Structure at Home
Structure does not change zoning, but it changes liability and paperwork. Fees below are from the Secretary of State fee schedule.
| Option | Cost | Notes |
|---|---|---|
| Sole proprietorship | No state filing | No liability protection; register a fictitious name if you use a trade name. |
| Fictitious name (DBA), Form Corp. 56 | $7 | Filed with the Secretary of State; see Missouri fictitious name registration. |
| LLC (Form LLC 1) | $50 online, $105 paper | No annual report for LLCs, per the Secretary of State FAQ. Compare services in LLC formation services in Missouri or read how to start an LLC in Missouri. |
| Corporation (Form Corp. 41) | $58 for authorized capital of $30,000 or less | Annual registration report: $20 online, $45 paper. |
A registered agent with a Missouri address is required for LLCs and corporations. If you do not want your home address on the public record, a commercial registered agent can use theirs; that is a privacy choice, not a legal requirement. The Secretary of State explains the rules on its general services and filings page.
Insurance and Home Occupancy
Standard homeowner's and renter's policies commonly exclude or limit business activity. We have no state rule to cite here, so the practical step is a call to your carrier: ask in writing whether business property, client visits and liability are covered, and if not, whether an endorsement or a business owner's policy fills the gap. An insurance agent or licensed adviser can price that for your situation.
Compliance Checklist
- Check lease, deed and HOA restrictions
- Ask the city or county zoning office whether your business is no-impact and what approvals it still wants
- Get the local business license if your city requires it
- Register with DOR for sales tax if you sell taxable goods or services
- Register for withholding, unemployment and workers' compensation if you hire
- File a fictitious name if you use a trade name
- Choose and file your legal structure
- Tell your insurance carrier about the business
Common Mistakes
Assuming a state rule overrides a city rule or the reverse: RSMo 71.990 protects no-impact businesses, but it does not cover a business with regular client traffic or employees on site.
Paying a "home occupation permit" fee before asking: in several cities the paperwork is a zoning clearance or questionnaire tied to the business license, and some cities do not charge separately.
Skipping sales tax registration because you work from home: the location of your desk does not change the DOR requirement or the penalty above.
