Calculation summary
Planning estimate only. Calculations retain decimals; displayed money is rounded.
Understand your estimate
What these numbers mean
Use this result as a planning checkpoint, then verify the inputs and official rules that apply to you.
What these numbers mean
The result moves from gross business inflows to net earnings, estimated SE tax, and an after-SE-tax planning amount.
How they were calculated
Returns and expenses reduce gross receipts, other business income is added, and positive net profit feeds the configured self-employment-tax calculation.
Common mistakes
Do not mix gross and net 1099 amounts, omit returns or fees, count personal expenses, or ignore W-2 wages affecting the wage base.
Important assumptions
Negative profit does not create negative SE tax in this tool; filing status and W-2 wages are used only where labeled.
Why an actual return may differ
Multiple Schedule C activities, partnership income, optional methods, loss limits, and return-level deductions can produce different results.
How this calculator works
The calculator uses only the values shown in the form. User-entered percentages, limits, recovery periods, mileage rates, and eligibility assumptions are not treated as official defaults.
Hypothetical example
Hypothetical: A hypothetical consultant enters $90,000 of receipts, $2,000 of refunds, $18,000 of expenses, and $1,000 of other business income. The example is not an actual taxpayer result or a promise of tax treatment.
Important limitations
This calculator does not prepare or file a return, determine legal eligibility, select accounting or depreciation methods, apply every annual limit, or calculate state-specific law. Verify current official instructions and individual facts.
