  Freelance Rate Floor

  S-Corp vs Sole Prop Breakeven

  At what revenue the S-corp election pays off, counting payroll service, the extra return and state fees — and it says so when it does not pay off.

  Rate Benchmark

  What freelancers in your discipline actually charge. Collecting responses now; published by segment once there are enough.

Built in the order that answers the most common question first. The engine behind all of them is already written and tested — see the methodology.
