Frequently Asked Questions
When does an S-Corp usually make sense?
Generally when net income reaches a level where payroll tax savings outweigh added costs and compliance. This calculator helps estimate that break-even point.
Does it include State Taxes?
Yes — estimates can vary significantly by state, which is why entity decisions should never be made in a vacuum.
Is a S-Corp always Better Than a LLC?
No. In some cases, staying an LLC results in lower overall tax or simpler compliance.
Is this a final tax calculation?
No. This is an estimate for planning purposes. Final outcomes depend on your full tax picture.
