Assumptions
- Models federal income tax and self-employment tax only. State tax, tax credits (Child Tax Credit, EITC), AMT, NIIT and phase-outs are not included.
- Standard deduction figures reflect the 2025 federal changes; itemized deductions are used only when they exceed the standard amount.
- Half of self-employment tax is deducted before computing adjusted gross income, as on Schedule 1.
Estimates only, not a substitute for a prepared return. Figures reference IRS guidance for Tax Year 2026; confirm the current rates before relying on them.
