Central US Location

Missouri at geographic center of US. Kansas City and St. Louis both major logistics hubs.

Within 1-day truck drive of 70% of US population. Ideal for distribution, ecommerce fulfillment, logistics companies.

Tax Considerations

Missouri income tax: 0-4.95% graduated brackets (low rates, reasonable structure). Pass-through taxation like all LLCs.

No franchise tax. No gross receipts tax. Sales tax: 4.225% state + local (varies by county, typically 5-9% combined).

Kansas City Earnings Tax

Kansas City charges 1% earnings tax on business income earned in city limits. Applies to both residents and non-residents working in KC.

St. Louis has similar 1% earnings tax. Factor this in if operating in either city.

Operating Agreement

Not required by MO law but HIGHLY RECOMMENDED for all LLCs.

Missouri courts enforce Operating Agreement provisions. Critical for multi-member LLCs to prevent disputes.

Foreign LLC

Out-of-state LLCs doing business in Missouri must register as foreign LLC. $105 filing fee.

Annual registration still required: $0/year (free but must file).

When Foreign Registration Required

Maintaining office in MO, employing MO workers, owning MO real estate, regularly conducting business in state.

Online sales to MO customers typically don't require foreign registration (no physical presence).

Common Mistakes

Not filing free registration: Many assume $0 fee = no filing required. Must file annually even though free.

Forgetting city earnings tax: Kansas City and St. Louis both charge 1% earnings tax on top of state taxes.

Missing 60-day name reservation: Missouri's 60-day reservation shortest in Midwest. Can't extend, must refile.

When MO Makes Sense

Choose Missouri LLC if: Want cheapest LLC in Midwest ($50 + $0/year), central US location important for logistics, operating in Kansas City or St. Louis metro, value low-tax environment.

Best for: Logistics companies, distribution centers, ecommerce fulfillment, businesses serving central US, cost-conscious startups.

Consider alternatives if: Need Kansas City/St. Louis location but object to city earnings tax, require faster than 3-5 day processing regularly, operating primarily on coasts.

Logistics & Ecommerce
