S-Corp Tax Comparison Calculator
Screening comparison of sole-proprietor SE tax and modeled S-Corp owner/employer FICA with selected published NJ filing amounts shown separately. It does not calculate net savings, project a full return, price outside providers, select an entity, or provide formation services.
Compare S-Corp TaxesSE Tax Calculator
Estimate selected 2026 federal self-employment-tax components for one self-employed person, including Social Security, Medicare, and Additional Medicare coordination. It does not calculate New Jersey tax, QBI, or a complete return.
Calculate SE Tax1099-DA Basis-Gap Calculator
Compare the modeled tax difference under entered assumptions between a zero-basis scenario and the supported basis entered. This arithmetic screen does not predict a filed-return result.
Calculate the GapEstimates Are a Starting Point
These calculators give you a directional number, not a tax return. Every calculation involves assumptions about income, deductions, credits, and state-specific rules that vary by situation. Use these tools to review modeled tax amounts and differences. The S-Corp comparisons do not select an entity or provide formation or election setup.
A separately accepted written scope may include full-return tax planning or preparation; a calculator result and contact-form submission do not create an engagement.
