What is a Sole Proprietorship?
A sole proprietorship is a business that is owned and operated by a single individual. Unlike limited liability companies (LLCs) and corporations, the owners of sole proprietorships do not have to register to operate in the state in which they do business. You can start a sole proprietorship by completing business-related tasks, as long as you are the single owner of that business.
Although sole proprietorships don't have complex start-up regulations or requirements, you may need to follow certain laws in your area to make sure your business is legal and legitimate. Examples of requirements include:
- Obtaining a business license
- Registering the business
- Following all permit laws
It's also important to understand the business debt and income tax obligations. Sole proprietors are held personally responsible for business debts and tax requirements. When you want to start a business, forming a sole proprietorship is the least expensive and simplest way to do so. However, a sole proprietorship doesn't offer any limited liability protection, which means your personal assets could be at risk if someone takes legal action against the business or the company accrues debt. Additionally, sole proprietorships offer limited options for tax planning.
Starting the sole proprietorship is easy. The first time you complete a business-related task, you have officially started a business. You don't need to file any forms or documents unless the business name is different from your name.
Business Formation Documents for Sole Proprietorships
While setting up a sole proprietorship doesn’t require as many official forms as other business structures, certain business formation documents are still essential to ensure the business operates legally. These documents help verify that the business is registered and follows local regulations.For sole proprietorships, typical business formation documents may include:
- DBA (Doing Business As) registration, if the business name is different from the owner's legal name.
- Local business licenses, which can vary depending on the type of business and location.
- Zoning permits, if the business involves physical locations like retail stores or offices.
For sole proprietors, the paperwork is usually minimal, but it's still crucial to complete these documents to stay compliant with local, state, and federal regulations. Not doing so can lead to fines or issues when dealing with customers, vendors, or financial institutions.Even though a sole proprietorship does not require Articles of Incorporation or Operating Agreements like an LLC or corporation, it is important to keep all necessary business formation documents organized and updated.
Sole Proprietorship vs Single Member LLC
When comparing a sole proprietorship vs single member LLC, the decision largely hinges on liability protection, taxes, cost, and administrative requirements. Below is a breakdown to guide your choice:
Liability Protection:
- Sole Proprietorship: The owner and business are legally the same entity. This means you're personally liable for any business debts or lawsuits.
- Single Member LLC: Offers limited liability protection, legally separating the business from the owner's personal assets.
Taxation:
- Sole Proprietorship: Income is reported on the owner’s personal tax return (Form 1040, Schedule C). No separate business tax filing.
- Single Member LLC: Typically taxed the same way as a sole proprietorship by default, but can elect to be taxed as an S Corp or C Corp for potential tax savings.
Startup and Compliance Requirements:
- Sole Proprietorship: Minimal setup. Usually requires a business license and possibly a DBA ("doing business as").
- Single Member LLC: Must file Articles of Organization with the state, pay a filing fee, and often maintain annual reports or pay franchise taxes.
Credibility and Growth Potential:
- LLCs may offer more credibility with lenders, vendors, and customers. They also provide more flexible ownership options if the business expands.
Cost Comparison:
- Sole Proprietorship: Often free or low-cost to start.
- Single Member LLC: Typically involves initial state filing fees ($50–$500 depending on the state) and ongoing costs such as annual fees or franchise taxes.
When to Choose Each:
- Choose a sole proprietorship if you're starting small, want to keep costs low, and aren’t concerned about personal liability.
- Choose a single member LLC if you want legal protection, plan to scale, or want to customize your tax treatment.
Key Business Formation Documents for Single Member LLCs
Unlike sole proprietorships, single member LLCs require more formal documentation to establish the business as a separate legal entity. Some of the necessary business formation documents for single member LLCs include:
- Articles of Organization: This document officially forms the LLC and includes key details such as the LLC’s name, address, and purpose. It must be filed with the state’s business registration office.
- Operating Agreement: While not always required by law, this document is highly recommended. It outlines the management structure, responsibilities, and ownership of the LLC, even if there is only one member.
- Employer Identification Number (EIN): This federal tax number is necessary for opening a business bank account and handling employee taxes.
- Business Licenses and Permits: Like a sole proprietorship, a single member LLC may need local or industry-specific licenses and permits to legally operate in its jurisdiction.
These documents create the legal framework for the LLC and help separate the owner’s personal assets from the business. The Articles of Organization and Operating Agreement are critical to establishing the LLC’s structure and compliance with state laws.
Fictitious Name Affidavit
If you choose a different name for your business, you will likely need to fill an affidavit for a fictitious owner. This affidavit provides information to the public and the local government agencies, including who owns and operates the business as well as the assumed name under which the business is operating. After filing your affidavit for a fictitious name, make sure to retain a copy of the form. You may need it to open a bank account under the business name or to take care of other business tasks.
You should file the affidavit with the county clerk's office in each county where your business will operate. When the business operates in multiple states, the process of operating under a fictitious name can become more complex because rules and forms vary between states. If this applies to your business, talk to an attorney who can help you complete and file all required paperwork.
As you're deciding what to name your business, it can be tough to choose between a fictitious name and your own name. If you are well-known or respected in your field, use your own name since it can be a great tool for marketing. One of the risks that comes with using your own name is the potential repercussions of the business encounters legal or financial trouble or fails. Any future business endeavors may be associated with the troubles you had in the past since your name was on the failed company.
Business License
In some jurisdictions, a business license is a requirement to operate a sole proprietorship. If this requirement applies in your area, you may not conduct any business until you obtain the proper license. You can learn more about the requirements and regulations in your locality by speaking to the county clerk. This individual can provide the forms you need and answer any questions about forming a sole proprietorship.
Whether you plan to provide a service or sell a product with your sole proprietorship, it's important to make sure all activities are handled in a professional way. Some of the most important tasks for business owners include devoting enough time and setting up and registering the business properly. By going through the correct processes, you can:
- Minimize taxes and fees
- Achieve greater success
- Avoid major issues
How to Start a Sole Proprietorship
You don't have to take any legal or formal steps to start a business that will operate as a sole proprietorship. There are no local, state, or federal requirements that apply to starting a sole proprietorship. However, some municipalities and cities do require business owners to obtain any necessary licenses or register the company.
