Use to estimate federal quarterly tax payments from nonidentifying income, entity, withholding, and prior-year tax figures. Return the assumptions, safe-harbor context, and due dates.
Input schema
| Property | Type | Required | Description |
|---|---|---|---|
| ytd_net_income_usd | number | yes | Your net self-employment / business income so far THIS year (year to date), before tax. |
| entity | string | yes | How the income is taxed. Sole proprietor / SMLLC / partnership pay self-employment tax; S-corp shareholders take wages (withheld) plus distributions. |
| state | string | no | US state. Only California installment timing is modeled specifically; when omitted, no state is assumed and only federal figures are computed. |
| ytd_withholding_usd | number | no | Federal tax already withheld this year (e.g. from a W-2 or S-corp salary). Counts toward the safe harbor. |
| prior_year_total_tax_usd | number | no | Total federal tax on last year's return. Enables the prior-year safe harbor (often the easiest to hit). |
| prior_year_agi_usd | number | no | Last year's adjusted gross income (AGI). If over $150,000 ($75,000 MFS), the prior-year safe harbor rises from 100% to 110%. |
