published on 22 January 2024

Running a small business in Missouri can feel overwhelming when it comes to navigating taxes.

This guide will provide clarity on the key taxes Missouri small business owners need to be aware of and how to effectively manage tax compliance.

We'll explore the basics of the Missouri tax structure, including details on income taxes, sales and use taxes, employment taxes, tax filing procedures, and resources available to support small business owners.

Introduction to Missouri's Small Business Tax Landscape

Missouri has a business-friendly tax climate with no corporate income tax and a low individual income tax rate. As a small business owner in Missouri, it's important to understand the key taxes that may apply to your business.

Understanding the Missouri Small Business Tax Rate

The Missouri small business tax rate you pay will depend on the legal structure you choose for your business.

  • Sole proprietorships and single-member LLCs are not taxed separately from their owners. Income flows through to the business owner's personal tax return. Personal income tax rates in Missouri range from 1.5% to 5.4%.
  • Partnerships and multi-member LLCs also pass income through to the owners' personal tax returns. Owners pay personal income tax rates on their share of business profits.
  • S-corporations and C-corporations pay no corporate income tax in Missouri. Owners of S-corps pay personal income tax on distributed profits.

In addition to income tax, your small business may need to collect and remit Missouri sales tax or payroll taxes. Understanding Missouri's tax rules upfront makes tax compliance easier down the road.

Missouri LLC Online Filing: A Step-by-Step Guide

Forming an LLC in Missouri can easily be done online through the Missouri Secretary of State website. Here are the key steps:

  • Choose an available business name and register it
  • Designate a registered agent
  • File articles of organization
  • Create an operating agreement
  • Obtain any necessary business licenses or permits

The filing fee for a Missouri LLC is $50, and you can expect the online filing process to take less than an hour.

The Role of the Missouri Department of Revenue in Small Business Taxation

The Missouri Department of Revenue administers tax laws in the state. Key services they provide to small businesses include:

  • Guidance on Missouri tax obligations and compliance
  • Online systems for filing and paying business taxes
  • Resources to understand Missouri tax rates, rules, forms, and deadlines
  • Audit assistance and appeals process

Checking in with the Department of Revenue early on ensures your small business understands applicable taxes and stays compliant. They want to help businesses get tax details right the first time.

Starting and operating a Missouri small business does not need to be complicated from a tax perspective. Understanding the basics around income taxes, sales taxes, employment taxes, and Missouri's helpful resources prepares you for smooth sailing.

What are the taxes for a small business in Missouri?

Missouri has a moderately competitive tax environment for small businesses. Here are some of the key taxes to be aware of:

Corporate Income Tax

Missouri has a corporate income tax rate of 4.0%. This applies to C-corporations and LLCs that elect to be taxed as corporations.

Individual Income Tax

Sole proprietors and pass-through entities like S-corporations and LLCs are taxed at the owner's individual income tax rate, which ranges from 1.5% to 5.4%.

Sales Tax

Missouri has a 4.225% state sales tax rate. Local jurisdictions can add up to 5.763% extra, for a maximum possible combined rate of 9.988%. As a business owner, you are responsible for collecting and remitting sales tax.

Property Tax

This varies widely across Missouri counties and cities. Expect to pay property tax on any real estate you own for your small business.

Employment Taxes

This includes state and federal unemployment insurance, workers comp, and withholding taxes. Rates vary based on number of employees, industry risk factor, and other variables.

Be sure to consult a qualified Missouri accountant and tax advisor to ensure full compliance and maximize savings. The Missouri Department of Revenue also provides useful resources for small business taxes.

What do LLCs need to file taxes in Missouri?

For LLCs electing to be taxed as corporations, Form MO-1120 must be filed in Missouri. A single-member LLC that is considered disregarded for federal taxation purposes must report income and expenses accrued by the LLC on the member's tax return.

In Missouri, a state tax identification number is required to file taxes. To obtain this, LLCs can:

  • Apply online through the Missouri Department of Revenue's website
  • Submit Form MO-1120, which serves as both the business registration and state tax ID application
  • Visit a local Missouri Department of Revenue office

Some key things Missouri LLCs need to file taxes:

  • Federal Employer ID Number (EIN): Obtained from the IRS, required if having employees or multiple members
  • Missouri State Tax ID: Received after registering the business with the Missouri DOR
  • Accounting records: Income, expenses, assets, liabilities
  • Completed tax returns: Such as Form MO-1120 for LLCs taxed as corporations

Additional requirements depend on the LLC's individual situation regarding number of members, elected tax structure, etc. But generally, keeping organized tax records and obtaining the proper identification numbers are essential first steps for Missouri LLCs to file their annual tax returns correctly under state law.

How do I structure my business to avoid taxes?

If your business operates as a sole proprietorship or other business structure, it may be beneficial for your tax liability to make the switch to a Limited Liability Corporation or LLC. Many small business owners are able to omit the employer portion of their FICA taxes and decrease their tax liability.

Here are some key things to consider when structuring your Missouri business:

  • LLC vs Sole Proprietorship: An LLC provides liability protection and may allow you to avoid paying self-employment taxes. As a sole proprietor, you are personally liable and must pay the full 15.3% self-employment tax.
  • Online Filing: You can easily set up an LLC in Missouri through the Missouri Secretary of State website. The filing fee is $50 and you can complete it yourself without a lawyer.
  • Taxes: LLCs are pass-through entities, so profits/losses pass to the personal returns of members. You may save on self-employment taxes but still need to pay income tax.
  • Maintenance: Missouri requires LLCs to file an annual registration report and pay taxes quarterly. Keep your business address updated with the state.
  • Free LLC Search: Use the Missouri Business Search to check if your desired LLC name is available for registration.

Structuring as an LLC can provide tax savings for small business owners in Missouri. Be sure to maintain compliance with state requirements to keep your LLC in good standing. Consult with an accountant to determine the best tax treatment for your business.

What is the nexus threshold in Missouri?

The nexus threshold in Missouri refers to the sales volume threshold that determines if an out-of-state seller must collect and remit sales tax in the state. Specifically, out-of-state sellers with over $100,000 in annual sales to Missouri customers are required to register with the Missouri Department of Revenue, obtain a Missouri sales tax permit, and begin collecting and remitting sales tax.

This $100,000 threshold applies to all sales of tangible personal property that are shipped to Missouri customers, including sales made through online marketplaces and platforms. Once an out-of-state seller exceeds $100,000 in gross annual Missouri sales, they meet Missouri's economic nexus threshold and must begin full compliance with Missouri sales tax laws.

Some key things for out-of-state sellers to know about Missouri's nexus threshold include:

  • The $100,000 threshold includes all taxable sales of tangible goods and products shipped to Missouri customers in a calendar year, regardless of the seller's physical presence in the state.
  • Marketplace facilitators like Amazon, eBay, Etsy, etc. also must collect Missouri sales tax once sales exceed $100,000.
  • Sellers must register for a Missouri Retail Sales License and begin collecting state and local sales taxes at the combined rate applicable to the delivery address.
  • Nexus thresholds can change, so sellers should monitor updated guidance from the Missouri Department of Revenue.

In summary, out-of-state sellers with over $100,000 in annual Missouri sales must register, collect, file, and remit applicable sales taxes to comply with Missouri's economic nexus law. Careful monitoring of sales thresholds is crucial to remain compliant.

Starting Your Business in Missouri: The Essentials Checklist

Choosing Your Business Structure: LLC, Corporation, or Sole Proprietorship

When starting a business in Missouri, one of the first decisions you'll need to make is choosing your legal business structure. The most common options for small businesses are:

  • Limited Liability Company (LLC): An LLC provides personal liability protection for business owners while allowing pass-through taxation. LLCs have less paperwork and formalities than corporations.
  • Corporation: Corporations provide the highest level of personal liability protection but are subject to double taxation. Corporations require more paperwork, formal meetings, and record keeping.
  • Sole Proprietorship: As a sole proprietor you and your business are considered one entity. This offers no personal liability protection but is the easiest structure to set up.

Each structure impacts how your business income is taxed, your personal liability, paperwork requirements, and ease of setup. Consider consulting a tax professional or attorney to determine the best fit.

Missouri LLC Search: Finding the Perfect Business Name

Before registering your Missouri LLC, you'll want to conduct a business entity search to ensure your chosen name isn't already taken. You can perform a free Missouri LLC name search directly through the Missouri Secretary of State.

Your LLC name must end in "LLC", "L.L.C." or "limited liability company". It cannot contain words restricted by state law. If your desired name is taken, consider alternatives or additions such as your location or business type.

Missouri LLC Registration: Your First Official Step

To register a Missouri LLC, you'll need to file Articles of Organization with the Secretary of State, including:

  • Your LLC name
  • Registered agent's name and Missouri address
  • Principal place of business
  • Duration of LLC

You'll also need to pay a $50 filing fee. The process can be completed online through the Secretary's website or by mail.

Registering a Missouri Sole Proprietorship: Simplicity and Ease

Registering a sole proprietorship in Missouri is straightforward. As a sole proprietor, you can operate your business under your own personal name without any formal registration. However, you may choose to register a fictitious name by filing a simple DBA form with your county clerk's office.

The ease of setup comes with tradeoffs like unlimited personal liability and no options for pass-through taxation. But for simple businesses, sole proprietorships provide simplicity and low startup costs. Consider consulting a tax professional to determine if this model suits your needs.

This section will cover the specific steps involved in understanding and managing the tax obligations for Missouri small businesses, including income, sales, and employment taxes.

Calculating Income Taxes for Missouri Small Businesses

All businesses in Missouri need to pay both federal and state income taxes based on their net income. Here are some key things Missouri small business owners should know:

  • Sole proprietors report business income on their personal tax returns using Schedule C. Your business income gets taxed at your personal income tax rate.
  • Partnerships and multi-member LLCs file informational returns showing each partner's share of income. The individual partners then report this on their personal returns.
  • C corporations and S corporations file separate business tax returns. C corps pay taxes on corporate income, while S corps pass income to shareholders who report it personally.

Use Missouri's online tax calculator to estimate your small business's state income tax liability based on expected net income each year. Tax rates range from 1.5% to 5.4%.

Sales and Use Taxes for Small Businesses in Missouri

If you sell taxable goods or services in Missouri, you must collect and remit sales tax unless you qualify for an exemption. The state sales tax rate is 4.225%, plus local taxes can bring it up to over 10% in some areas.

Some key sales tax rules for Missouri small business owners:

  • You must collect sales tax if you have a physical presence or "nexus" in Missouri, which can include employees, property, inventory, etc located in the state.
  • Delivery charges, shipping & handling fees, and installation labor may also be taxable.
  • Use tax applies if you purchase taxable goods or services without paying sales tax at the time of purchase. You report and pay use tax directly to the state.

Register to collect/remit sales tax through the Missouri Department of Revenue.

Employment Taxes and Withholding Requirements

If you have employees, you are responsible for payroll taxes like:

  • Social Security and Medicare: Withhold 6.2% of wages for Social Security and 1.45% for Medicare. You also pay matching employer contributions.
  • Federal unemployment tax (FUTA): You pay 6% on the first $7,000 of each employee's annual wages. Rates can vary year to year.
  • State unemployment insurance: Tax rates range from 0.00% to 9.75% on the first $15,000 of each employee's wages.

In addition, you must withhold Missouri state income tax from employee wages if they are Missouri residents. Refer to the Missouri Employer Tax Guide for further details on requirements.

Stay compliant on payroll taxes by registering for an EIN, filing forms W-2 and W-3, depositing payroll taxes on time, and accurately reporting withholdings. Consider using payroll software or working with an accountant to simplify the process. Failing to handle employment taxes properly can lead to penalties.

Reporting and Payment Procedures for Missouri Small Business Taxes

Filing Income Tax Returns for Your Small Business

As a Missouri small business owner, you are required to file annual income tax returns reporting your business's profits and losses. Here are the key details on fulfilling this obligation:

  • Use Form MO-1040 to report your federal Schedule C business income on your personal tax return. This is common for sole proprietors.
