LLC vs S-Corp: Which Is Right for Your Business?

Business entity structure affects taxes, liability protection, and compliance obligations. The two most popular options for small business owners are Limited Liability Companies (LLCs) and S-Corporations (S-Corps). Both provide liability protection, but they differ in terms of taxes, compliance requirements, and administrative burden.

An LLC is a flexible business structure that offers personal liability protection while allowing you to choose how you're taxed. By default, a single-member LLC is taxed as a sole proprietorship, and a multi-member LLC is taxed as a partnership. However, you can elect to have your LLC taxed as an S-Corp by filing Form 2553 (Election by a Small Business Corporation) with the IRS. An S-Corp is a tax election available to corporations and some LLCs that eliminates the 15.3% self-employment tax on distributions (salary is subject to FICA payroll taxes, while distributions avoid both FICA and self-employment tax). With an S-Corp election, you split income between a reasonable salary (subject to FICA payroll taxes and income tax) and distributions (subject to income tax but not self-employment tax), which reduces your combined self-employment tax and income tax liability.

The differences between LLC and S-Corp structures include: (1) Taxation: LLCs offer flexibility, while S-Corps require splitting income between salary and distributions; (2) Self-Employment Tax: S-Corps can save 15.3% in self-employment taxes on distributions, applicable to businesses with net income above the reasonable salary threshold; (3) Complexity: S-Corps require more paperwork, including separate tax returns, payroll processing, and corporate formalities; (4) Cost: LLCs cost less to form and maintain, while S-Corps involve additional accounting and payroll costs. An LLC involves lower formation and maintenance costs than an S-Corp election (no separate payroll, no corporate tax return filing). For profitable services businesses (consultants, contractors, lawyers, doctors), an S-Corp election eliminates the 15.3% self-employment tax on the distribution portion, offset by additional payroll and compliance costs.
