LLC vs S-Corp: Side-by-Side Comparison

The single biggest tax decision most small business owners make is whether to stay a default LLC or elect S-Corp status. The difference comes down to self-employment tax: a sole proprietor or single-member LLC pays 15.3% SE tax on every dollar of profit, while an S-Corp owner pays payroll tax only on a reasonable salary — distributions above that escape it. Here is how they compare on the factors that actually matter.

The Bottom Line

Rule of thumb: below roughly $40,000–$50,000 of annual profit, the payroll and filing costs of an S-Corp usually outweigh the savings. Above that, savings grow with profit — often $5,000–$15,000 per year in the $80K–$200K range.
