There are quite a few factors to consider when you’re choosing the legal structure for your company, but the most important is liability. Tax issues come in second place for this decision, followed by the amount of formal paperwork you’re willing to do.

Here’s why liability is the number one thing to consider: If you set up your company as a sole proprietorship or partnership, you are personally 100% financially liable for any and all debts of the business. That means if your business loses a lawsuit, and there’s not enough money in the company bank account, your personal wealth – your house, your car, your emergency savings – is all at risk.

That is even trickier in a general partnership. Each partner is fully liable for 100% of the business debts. So if your partner takes off, dies, or declares personal bankruptcy, you are on the hook for everything. I’m not trying to scare you out of forming a partnership – though I generally do NOT recommend them – but it’s really crucial that you’re aware of the risk potential before choosing that legal structure for your company.

Of course, liability is not the only issue that comes into play when you’re deciding how to set up your company.

The chart below highlights the special features of each business entity, to make it easier for you to figure out which best fits your situation.
