Steps to Starting a Business in Missouri

Step 1: Choose a Business Idea

The first step in starting a business in Missouri is having a good business idea. Maybe you already have an idea picked out, or maybe you are still deciding on one. Regardless, you can check out our library of business ideas to get detailed industry information, trends, costs to start, tips, and lots more.

Step 2: Write a Business Plan

Once a solid business idea is in place, it’s time to start working on the business plan.

Many people only consider writing a business plan because the bank asks for one in order to get funding. While that’s a valid reason, more importantly, writing a business plan gets the ideas out of the entrepreneur’s head and helps create a roadmap for where they want the business to go. Just as most builders wouldn’t build a house without blueprints, an entrepreneur shouldn’t build a business without a business plan.

The thought of writing a business plan is overwhelming, so here are some resources to help in getting started.

Step 3: Select a Business Entity

The next step in starting a business in Missouri is selecting a business entity.

The business entity is sometimes referred to as a business structure or legal entity, which refers to how a business is legally organized. There are four primary business entities: sole proprietorship, partnership, corporation, and Limited Liability Company (LLC). A brief description of each is below.

Sole Proprietorship is an individual that decides to go into business. This is the easiest and least expensive of the four entities to set up as there is no state filing. The ease of startup is a big selling point; however, a major downside to the sole proprietorship is that the owner is personally responsible for all debts and actions of the company. If the business is sued, the owner’s personal assets are potentially at risk. Another potential downside is that the owner will pay self-employment tax on all business profits and may be more costly than some other entities.

General Partnerships consist of two or more people conducting a business together. Like the sole proprietorship, there is no formal state filing. Also, like the sole proprietorship, the partnership has unlimited liability. If the partnership were to be sued, the partner’s personal assets are equally at risk. The partnership itself does not pay tax from business income. Instead, profits and losses are passed through to the owner’s personal tax return. This income is subject to self-employment tax.

Corporation is a business structure that is a separate entity from the individual. While corporations are more expensive and difficult to form than sole proprietorships and partnerships, the major advantage is that the corporation provides personal asset protection for the owners, should the corporation be sued. The downside is the compliance requirements and administrative burdens of having a board of directors, annual meetings for directors and shareholders, taking minutes at the meetings, issuing stock certificates, and more.

There are multiple ways a corporation can elect to be taxed, which includes the C-corporation and S-corporation. Electing how the entity should be taxed is complicated, so be sure to talk with your CPA as there is the potential of double taxation where profits and dividends are both taxed. Also, there is no self-employment tax with a corporation, as income to the owner(s) will come from either a salary or dividends, which may be beneficial.

To form a corporation, the Articles of Incorporation need to be filed with the Secretary of State. The state filing fee for corporations is $58, provided they have $30,000 or less in authorized capital.

The Limited Liability Company (LLC) is a popular business entity choice. It provides the liability protection of a corporation with the ease of operation like a sole proprietorship. The Limited Liability Company does not have the many burdens a corporation such as holding a board of directors meeting, shareholders meeting, taking minutes, appointing a registered agent, etc. The LLC also has the greatest tax flexibility of the four entities. Income can be taxed as a pass-through entity like the sole proprietor or partnership or as a corporation.

To form a Missouri LLC, the Articles of Organization need to be filed with the Secretary of State. The state filing fee is $50 when filing online or $105 when filing by mail.

Step 4: Register a Business Name

After deciding on the business entity, the next step in starting a business in Missouri is to register the business name.

Registering a Missouri Fictitious Business Name for Sole Proprietorships & General Partnerships

A business doing business under a name other than their own (sometimes referred to as a DBA or Doing Business As) is required to file a Fictitious Name Registration with the Missouri Secretary of State.

Registering a Missouri Business Name for a Corporation or LLC

Corporations and LLCs will pick a name at the time of formation. This name has to be different from the other entities registered with the Missouri Secretary of State. Registering the entity name will not provide much protection from anyone else from using the name, other than being able to register the entity with the Secretary of State.

Legally Protect Your Business Name

A trademark can legally stop others from using names, slogans, or logos. The U.S. Patent & Trademark Office (USPTO) manages the registration of trademarks.

Before settling on a name, you will want to first check and make sure the name you want to use isn’t already registered to another business.

You can also register to keep others from using the name of your business, product, or service.

Step 5: Get an EIN

The Employer Identification Number or EIN (sometimes referred to as the Federal Employer Identification Number or FEIN) is a nine-digit tax identification number issued by the Internal Revenue Service (IRS). This number identifies a business operating in the U.S and is used for paying payroll taxes, filing tax returns, and more. Much like what a social security number is to a person, the EIN is similar to a social security number for a business. While most businesses will need to get an EIN, some do not.

Partnerships, corporations, and most LLCs OR sole proprietorships with employees MUST register for an EIN.

Sole proprietorships or a single-member LLC with no employees is NOT required to get an EIN. In these instances, the owner’s social security number is used to identify the business.

Filing the EIN can be done online through the IRS website, which only a few minutes, and the number is available immediately. Alternatively, an EIN can be registered by mail or fax by submitting IRS Form SS-4.

Step 6: Open a Business Bank Account

Keeping your business and personal finances in separate bank and credit card accounts makes it easier to track business expenses. Every bank is different, but in general, they will request:

Sole proprietorship & partnership – Trade Name Certificate, EIN or SSN and owner(s) drivers license
Corporation – Articles of Incorporation, bylaws, Certificate of Good Standing, EIN, and owner(s) drivers license
LLC – Articles of Organization, Operating Agreement, Certificate of Good Standing, EIN and owner(s) drivers license

Step 7: Apply for Business Licenses & Permits

There are several federal, state, and local rules and regulations Missouri businesses need to register for and comply with. Some common registrations include:

Business Licenses – The state of Missouri doesn’t have a general business license; however, many cities require a business license to operate.

Business Tax Registration – Businesses collecting sales tax through the selling of products and certain services and will collect sales tax, or are withholding taxes from employees, will need to register with the Missouri Department of Revenue.

Professional Licensing – Some services such as electrical contractors, accountants, interior designers, and tattoo artists require licensing in Missouri. While this isn’t a license on the business, licensing is required in order to operate.

Step 8: Find Financing

Obtaining the funds to start a small business is a challenging process for many.

Not only are there unfamiliar terms like collateral, equity, assets, liabilities, and others, but there are several sources of funding with different rules, processes, and costs.

From conventional bank loans, Small Business Administration (SBA) loan guarantees, investors, grants, and many others, it can be difficult to wade through what is available and best for your business.

Step 9: Hire Employees

Hiring employees is a complex and often overwhelming process for a new business owner as there are multiple agencies to register with and labor laws to understand.

Employers are responsible for reporting new hires, verifying employees are eligible to work in the U.S., income tax withholding, unemployment insurance, unemployment taxes, and payroll withholding taxes, including Social Security and Medicare.

Step 10: Obtain Business Insurance

Business insurance is never at the top of anyone’s list of things they want to do when starting their business; however, business insurance may be critical to protecting your business.

Most types of business insurance coverage is optional, except for workers’ compensation insurance in most states. Some states will also require professional liability insurance for businesses offering certain services and commercial auto insurance.

Even if insurance isn’t required, and there is a fire, theft, or personal injury lawsuit, the small business owner may have to pay out-of-pocket damages and legal fees. Home-based businesses and side-businesses may want to consider business insurance, too, as personal home and vehicle policies may not cover in the event of a business loss.

Step 11: Set up an Accounting System

Setting up an accounting system for your business is one of the most important things you can do for your company to ensure long-term success.

There is just one problem – you’re not a numbers person.

Just thinking about financial statements, debits and credits, and accounting software makes your head hurt.

Staying on top of finances not only keeps the business out of trouble with the IRS, but financial statements can be used to track and monitor trends in the business and maximize profits.

Fortunately, understanding the numbers doesn’t mean getting a finance degree. Tracking a business’s financials can be done with pen and paper (not really recommended), spreadsheets, accounting software, or hiring a bookkeeper.
