LLC, S-Corp, or Sole Proprietor? Choosing the Right Business Structure

By Matthew Slomowicz·June 12, 2026·5 min read

Choosing a business structure is one of the first real decisions a new owner makes, and it shapes taxes, liability, and even how bookkeeping gets set up — worth getting right from the start rather than changing later.

Sole proprietorship: simplest, least protected

A sole proprietorship requires no formal registration and is the default if you do nothing else — but it offers no separation between personal and business liability, meaning personal assets are exposed if the business is sued or can't pay a debt.

LLC: liability protection with flexibility

An LLC separates personal and business liability while keeping tax filing relatively simple — by default, profits pass through to the owner's personal tax return, avoiding the double taxation of a traditional corporation.

S-corp election: a tax strategy, not a separate entity

An S-corp isn't a business structure on its own — it's a tax election an LLC or corporation can make once profits are consistent enough to justify running payroll for the owner, potentially reducing self-employment tax. It adds bookkeeping complexity, so it's usually not the right first move for a brand-new business.

The right structure depends on liability exposure, expected profit, and growth plans — it's worth a conversation with both an attorney and an accountant before filing anything.
