## Tools (3)

- `calculate_self_employment_tax`: Use this when the user asks how much self-employment tax or total federal tax they owe for 2026 on 1099 income: a self employment tax calculator or 1099 tax calculator, 'I made 60k on 1099, how much do I owe', 'how much to set aside for taxes as a freelancer', DoorDash/Uber/Etsy gig income taxes, or 1099 income on top of a W-2 job. Computes Schedule SE self-employment tax (92.35% of net profit, 12.4% Social Security up to the $184,500 wage base minus W-2 wages, 2.9% Medicare, 0.9% Additional Medicare Tax), the deductible half, the QBI deduction, 2026 federal income tax with the standard deduction and child tax credit, withholding offset, and the percent of profit to set aside. Returns a PDF worksheet and a calendar file. For whether quarterly payments are needed, how much to pay each quarter, safe-harbor amounts, or a missed payment, use plan_quarterly_payments. Federal only; does not file taxes, compute state tax, or give tax advice. Do not use for explaining what a 1099 form is or for filing a return.
- `find_estimated_tax_due_dates`: Use this when the user wants the quarterly estimated tax payment due dates for 2026 (tax year 2026: Apr 15, Jun 15, Sep 15, 2026 and Jan 15, 2027), which dates are past or next, the income period each payment covers, or calendar reminders (.ics) for those dates, with no income figures. Returns each date, days until it, and a calendar file. Does not calculate how much to pay; for amounts use plan_quarterly_payments. Do not use for state due dates or filing deadlines for the annual return.
- `plan_quarterly_payments`: Use this when the user asks whether they need to make quarterly or estimated tax payments for 2026 (Form 1040-ES), how much to pay each quarter, the safe-harbor amount to avoid an underpayment penalty, or how to catch up after a missed payment ('I missed my Q2 estimated payment'), including W-2 workers with 1099 side income who ask 'do I need quarterly payments'. Compares 90% of the 2026 estimate with the 2025 tax (100%, or 110% if 2025 AGI was over $150,000), subtracts W-2 withholding and payments already made, applies the $1,000 rule, and returns the amount for each due date (Apr 15, Jun 15, Sep 15, 2026; Jan 15, 2027) with past-due status, a calendar file with reminders, and a PDF worksheet. Federal only; does not compute the penalty amount, make payments, or give tax advice. Do not use for paying the IRS online or logging in to tax software.
