A Missouri LLC pays no federal entity-level tax under the default pass-through rules and reports profit on the owners' personal returns, where Missouri personal income tax reaches up to 4.7%. Single-member LLCs are disregarded entities; multi-member LLCs are partnerships. An S-corp election saves self-employment tax once net income clears $40,000-$60,000 a year. Non-resident owners of a foreign-owned single-member LLC file Form 5472 with a pro-forma 1120 each year, and most domestic Missouri LLCs are currently exempt from BOI reporting.
The IRS taxes a Missouri LLC as a pass-through by default, with no federal entity-level tax. A single-member LLC is a disregarded entity taxed on Schedule C of the owner's 1040; a multi-member LLC is a partnership. A multi-member LLC files Form 1065 and issues a Schedule K-1 to each member, who reports the share of profit on a personal return. Profit is taxed once, at the member level, whether or not it is distributed. This default treatment applies automatically the moment the LLC forms, with no election required, and it is the starting point for deciding whether an S-corp election makes sense later.
Missouri personal income tax reaches up to 4.7% on the profit that passes through to LLC members. Missouri levies no separate LLC entity-level income tax and no franchise tax on the LLC itself. Because the LLC is a pass-through, profit lands on each member's Missouri return at the individual rate. A non-resident member with Missouri-sourced income files a Missouri non-resident return for that portion. Missouri applies a graduated rate structure that tops out at 4.7% for 2026, which is lower than the top rate in many neighboring states and keeps the state tax cost predictable. Missouri also charges no franchise tax on an LLC. The state repealed its corporate franchise tax, so a Missouri LLC pays no annual entity-level charge based on capital or net worth, unlike Delaware's $300 flat franchise tax. Combined with the absence of an annual report fee, the LLC owes the state nothing simply for staying in business, and tax arises only when it earns Missouri-sourced profit.
A Missouri LLC elects S-corporation treatment by filing IRS Form 2553, which lets the owner take a reasonable salary and draw the rest as distributions that avoid 15.3% self-employment tax. The election earns its cost once net income clears $40,000-$60,000 a year. Below that threshold, the payroll-compliance burden, quarterly filings, a real salary, and a payroll provider, outweighs the self-employment tax saved. Above it, the distribution portion escapes the 15.3% charge and the savings compound each year. Missouri recognizes the federal S-corp election, so the entity keeps pass-through treatment at the state level while trimming federal self-employment tax.
A default Missouri LLC owner pays 15.3% self-employment tax on net business income: 12.4% Social Security up to the annual wage base of $168,600, plus 2.9% Medicare with no cap. This is on top of income tax. The self-employment tax funds Social Security and Medicare that an employee would split with an employer, so a sole owner carries both halves. An S-corp election reduces the exposure by moving the distribution portion of profit out of the self-employment tax base, at the cost of running payroll. For owners under the $40,000-$60,000 net-income range, the default treatment stays simpler and cheaper.
A non-resident owner owes US federal income tax only on income effectively connected to a US trade or business. A foreign-owned single-member LLC with no US-source effectively connected income files an information return but pays no US income tax on foreign-earned profit. The required filing is Form 5472 with a pro-forma Form 1120 each year for a foreign-owned disregarded entity; a multi-member LLC files Form 1065 with K-1s. An ITIN may be needed for a personal US tax filing. Missouri taxes only Missouri-sourced income, so a non-resident with no in-state activity carries no Missouri income tax. Anonymousllc.co partners with US tax preparers familiar with non-resident filings.
Form 5472 is an IRS information return required for any US disregarded entity with 25% or more foreign ownership that has reportable transactions. Most non-resident-owned single-member Missouri LLCs must file it annually. The form is filed alongside a pro-forma Form 1120 and reports transactions between the LLC and its foreign owner, such as capital contributions and distributions. It carries no income tax by itself, but the penalty for missing it starts at $25,000, so the filing is not optional for a foreign-owned LLC. Anonymousllc.co connects owners with preparers who handle the 5472 and pro-forma 1120 package each year.
A Missouri LLC that sells taxable goods or certain services in Missouri must register for a Missouri sales tax license and collect state and local sales tax. The obligation depends on the business activity, not the LLC form itself. Missouri combines a state sales tax rate with local add-ons, so the total rate varies by location. An LLC selling only to out-of-state customers, or providing non-taxable services, may have no Missouri sales tax duty at all. Economic nexus rules can also create a collection obligation in other states once sales into them cross a threshold. This is separate from the income tax that passes through to members.
Under the March 21, 2025 FinCEN interim final rule, domestic reporting companies are exempt from beneficial ownership information reporting. A Missouri-formed LLC files no BOI report today; only foreign reporting companies remain obligated. Most Missouri LLCs are domestic entities and fall inside the exemption, so there is nothing to file at present. A foreign reporting company registered to do business in Missouri stays obligated, and Anonymousllc.co files BOI for foreign reporting companies at $150 flat if the rule changes or a specific entity remains in scope. The rule continues to evolve, and the team tracks updates for clients.
Forming a Wyoming or New Mexico anonymous LLC and foreign-qualifying into Missouri does not change the federal tax treatment: the entity stays a pass-through and profit still lands on the owners' returns. The home state's tax rules apply alongside Missouri's. Wyoming and New Mexico levy no state income tax, so the only state income tax is Missouri's up to 4.7% on Missouri-sourced profit. The anonymous home state adds its own maintenance, Wyoming's $60 annual report license tax or New Mexico's none, but no extra income tax. The privacy structure shifts the ownership record off the public filing without raising the federal or Missouri income tax the business owes.
Yes. A Missouri LLC can elect C-corporation treatment by filing IRS Form 8832, which subjects profit to the 21% federal corporate rate and a second layer of tax when profit is distributed as dividends. Most small owners avoid this double taxation. The C-corp election suits an LLC raising venture capital or retaining earnings inside the company at the corporate rate, where the structure matters more than the double layer. For a business distributing most of its profit, the default pass-through or an S-corp election keeps total tax lower. Missouri follows the federal election, so a C-corp LLC also files a Missouri corporate return. The choice depends on growth and reinvestment plans, not on Missouri rules.
A default Missouri LLC reports profit on the members' personal returns, due April 15 for the prior calendar year, alongside the Missouri individual return. A multi-member LLC's Form 1065 is due March 15. Owners with meaningful profit make quarterly estimated federal and Missouri payments through the year to avoid underpayment penalties, due in April, June, September, and January. An S-corp LLC files Form 1120-S by March 15 and runs payroll on its salary portion. Because Missouri requires no annual report, these tax dates are the only recurring deadlines the LLC tracks, and a US tax preparer familiar with the entity keeps them on schedule.
