Choosing the Right Business Entity: LLC, S Corporation, or C Corporation

Entity selection is one of the few decisions that touches nearly everything else: how profit is taxed, whether you must run payroll, what your compliance calendar looks like, and how attractive the business is to an investor or buyer.

It is also reversible more often than people assume, so the goal is a structure that fits the next few years rather than a permanent commitment.

The LLC as a starting point

An LLC is a legal structure, not a tax classification. By default a single-member LLC is taxed as a sole proprietorship and a multi-member LLC as a partnership, but the same entity can elect to be taxed as an S corporation or C corporation. That flexibility is why many owners start here.

When an S corporation election makes sense

An S election can reduce self-employment tax by splitting owner compensation between reasonable salary and distributions. The savings only materialize above a certain profit level, and they come with obligations: running payroll, filing a separate return, and documenting that the salary is defensible.

• Consistent net profit well above a reasonable owner salary
• Willingness to run formal payroll and file quarterly returns
• A single class of stock and eligible ownership

Where a C corporation fits

C corporations face entity-level tax, but they suit businesses planning to reinvest heavily, raise institutional capital, or issue multiple classes of stock. For most closely held service businesses, the double-taxation drag outweighs the benefits.

Run the numbers before you file

The right answer depends on profit level, owner count, state taxes, benefits, and exit plans. Modeling two or three scenarios side by side almost always makes the decision obvious, and it takes far less time than unwinding the wrong structure later.
