S-Corp vs LLC taxed as partnership?

Both pass-through; S-Corp may save payroll tax on distributions but has salary requirement and ownership limits.

When is a C-Corp better?

Reinvesting profits, QSBS eligibility, venture investors preferring C-Corps, or foreign owners blocked from S-Corp.

What defines reasonable salary for S-Corp?
