Estimate setup
Annual income
S-corp/pass-through profit is included in ordinary income but not self-employment tax. PTET is modeled as reducing pass-through income and as a state payment or credit.
Deductions and credits
W-2 jobs are assumed to withhold at a normal annualized rate by default. Open advanced settings to switch to manual withholding, tune the coverage rate, enter prior-year tax, or add overpayments credited to the current year.
Results
What to pay next

Before relying on this estimate
- Collect year-to-date pay stubs and projected remaining pay.
- Separate W-2 wages from self-employment net profit.
- Separate S-corp/pass-through profit from self-employment income.
- Confirm whether PTET payments reduce business income, create a state credit, or require a state-specific addback.
- Estimate qualified dividends and long-term capital gains.
- Enter federal and state withholding already paid or expected.
- Check prior-year tax, AGI, and any overpayment elected for the current year before using the safe-harbor result.
- Confirm state, city, AMT, credits, and special rules with a tax professional.
Informational estimate only. This is not tax, accounting, legal, or investment advice and does not replace Form 1040-ES, state forms, tax software, or a qualified tax professional. State estimates use an editable simplified rate and selected state payment schedules, not a complete state return. W-2 withholding and PTET treatment are simplified planning assumptions.
Method notes
How to read estimated taxes
The calculator uses 2026 federal brackets, standard deductions, self-employment tax, net investment income tax, and a simplified qualified dividend / long-term capital gain calculation. It compares projected liability with withholding, estimates already paid, and prior-year safe-harbor targets.
State tax is modeled with an editable simplified rate by state. It does not calculate a complete state return, city tax, AMT, every credit, every deduction, special industry rules, disaster relief, or underpayment penalties. This calculator is for informational purposes only and is not tax, accounting, legal, or investment advice.
