2. Choose a Business Structure

After creating your business plan you’ll want to determine the legal structure for your business. Consider your comfort with personal liability risk, desired tax status, and source of capital. There are four common types of business structures to evaluate:

Limited Liability Company (LLC)

An LLC or limited liability company is a business structure that provides limited liability and pass-through taxation benefits. Think of it like incorporating a business without the extra formalities.

An LLC can help protect business owners from legal liability for company debts and other liabilities, just like a corporation. Because an LLC is treated as separate from its owners, individual owners don’t typically bear legal responsibility for business debts.

Pass-through taxation means that LLC income isn’t taxed separately but instead passed through to the owner(s). If the LLC has more than one owner, a tax return for the company must still be filed. The income or loss is shown on this return and passed through to the members. Members must report the income or loss on their personal tax returns and pay any necessary taxes.

In short, LLCs bring the benefits of both corporations and partnerships, along with easy maintenance and flexibility innownership arrangements.


A C corp (corporation) is a separate legal entity that can earn profits, be taxed, and held legally liable. However, forming a C corp is more expensive and requires extensive record-keeping, operational processes, and reporting. Nevertheless, it provides robust protection from personal liability. C corps pay income tax on profits, not owners. In some cases, corporate profits may be subject to double taxation, both at the company level and on shareholder dividends. C corps have an independent life from shareholders. Even if a shareholder leaves or sells their shares, the business can continue with few interruptions. Raising capital is easier for C corps as they can sell stock, attracting top talent. It’s a good option for medium- to higher-risk businesses that need money, plan to go public, or aim to be sold eventually. Overall, C corps offer many benefits but require careful consideration for success.

Sole Proprietorship

A sole proprietorship is a business structure where the owner operates and manages the company independently. In a sole proprietorship, the owner is personally responsible for all aspects of the business, such as profits, losses, investments, and liabilities. The advantage of this type of structure is that it’s easy to set up and manage since everything goes through the owner. It also enables the owner to keep all the profits and ultimately control their business decisions.

However, there are some downsides to this structure as well. For example, sole proprietors are personally liable for any debts or obligations incurred by their business. This means that if a lawsuit is filed against them, they can be held responsible for any losses. Sole proprietorships tend to have difficulty raising money since banks hesitate to lend to them. Finally, tax regulations may be more complicated since all profits and losses are reported on the owner’s personal income tax return.

A general partnership is a type of business where two or more people come together to make money. Unlike other types of businesses, like corporations, you don’t need to register a general partnership with the state. It’s a simple and easy way to start a business. When you’re in a general partnership, each person has unlimited liability for the business. If the company can’t pay its debts, you must pay them with your money. You also share the profits and losses of the business with the other partners.
