Legal Requirements for Launching a Small Business

Launching a small business is an exciting venture filled with opportunities and challenges. But before you start ordering your inventory, you must meet several legal requirements. These prerequisites ensure your business operates within the guidelines set by the government, minimize the risk of legal complications, and contribute towards establishing your business’s credibility.

Each state in the U.S. has different rules and regulations for starting a small business, hence requiring a thorough understanding to avoid potential roadblocks. One popular business structure is the Limited Liability Company or LLC.

In particular, setting up an Arizona LLC commands certain requirements that contribute to defining its legitimacy and operating compliance. Below are four key legal requirements that every small business entrepreneur should consider before launching their venture:

1. Choose a Business Structure

Your first legal requirement is to determine the structure of your business. Sole proprietorship, partnership, Limited Liability Company (LLC), or corporation are the most common forms of business structures. Each structure has its legal implications regarding taxes, liability, cost of formation, and bandwidth for complexity in management and decision-making.

A sole proprietorship is the simplest form, where the owner and the business are legally the same. In contrast, a corporation is a more complex structure and involves more extensive legal paperwork. An LLC offers a middle ground, providing some protection from personal liability but with less formality than a corporation. A well-informed decision will save you from unnecessary hardships in the future.

2. Register Your Business Name

The next critical legal requirement is registering your business name. Your chosen business name is not just a label; it’s a powerful branding tool that carries your business’s identity. As a result, protecting it by registering is crucial.

You need to ensure that your business name is unique and not already taken by another business entity. Check with your state business office to see if your chosen name is available and hasn’t been taken by another company. If available, you need to register it to protect your business brand and prevent other businesses from using the same name. If you have plans on expanding nationally, consider trademarking your business name.

3. Obtain Federal and State Tax IDs

All businesses with employees are mandated to apply for a federal tax identification number or Employer Identification Number (EIN) from the Internal Revenue Service (IRS). The EIN is particularly essential as it’s required for federal tax purposes and hiring employees.

Applying for an EIN is straightforward since you can do it quickly online at the IRS website. Besides the EIN, most states require businesses to get a state tax ID number as well. State tax ID numbers are used for tracking state taxes, and the requirement and process for getting one vary by state.

4. Apply for Necessary Permits and Licenses

Obtaining the necessary permits and licenses is the other crucial legal requirement. Without these documents, your business might not operate legally and risks both closure and fines. These licenses and permits often vary depending on the state, business type, and its location. This might include health department permits, zoning and land use permits, sales tax licenses, or general business licenses.

An overview of your business’s industry and the regulations surrounding it is critical to identify the necessary permits. Since failing to maintain required permits and licenses comes with hefty penalties, it’s essential to stay on top of these requirements. Aside from these initial legal considerations, remain vigilant about staying in compliance with all the laws and regulations that apply to your business throughout its operations.


Starting a small business involves more than just identifying a great idea and opening your doors. Preparation, careful planning, and ensuring legal compliance create a strong foundation and a pathway for your business’s success. It’s always recommended to seek advice from legal professionals to navigate the regulatory framework effortlessly. Understanding these requirements and incorporating them into your planning can ensure you confidently kickstart your journey as a small business owner.
