The point that trips people up most is that both can shield owners from personal liability, but they are not the same kind of business. An LLC, or limited liability company, is usually simpler to run and more flexible in how profits, management, and taxes are handled. A corporation is more formal, with shareholders, directors, and officers, and it follows stricter rules for meetings, records, and decision-making. Corporations can be taxed as separate entities, while many LLCs use pass-through taxation, though tax treatment can vary.

That difference matters in daily business and in lawsuits. If a worker, customer, or contractor is injured, the business structure can affect who the proper defendant is, what insurance applies, and whether an owner can be sued personally. In most cases, either structure protects the owner's personal assets unless there is fraud, serious misconduct, or grounds to pierce the corporate veil.

For an injury claim, the label on the company name is only the starting point. An LLC or corporation may own the property, employ the negligent worker, or hold the policy that pays a settlement or damages award. In South Dakota, fault rules still control the claim itself: the state uses a modified comparative fault system with a 51% bar and a slight/gross contribution standard, which can reduce or block recovery depending on each side's share of blame.
