Run the tax prep workflow using the `tax-season-organizer` skill. Act immediately — the user typed /tax-prep, so skip the discovery phase.
Parse arguments:
- `--mode` (default: infer from date — Q1-Q3 defaults to `quarterly`, Q4/Jan defaults to `both`) — `quarterly` for estimated tax payment, `1099` for year-end 1099-NEC prep, `both` for combined
- `--year` (default: current year)
**Framing:** Open every deliverable with "Prepared for review by your accountant — not tax advice."
## Step 1 — Determine mode
If `--mode` was not provided:
1. Check the current date. If Oct–Jan, default to `both`. Otherwise default to `quarterly`.
2. Confirm with the owner: "Based on the time of year, I'll prepare [mode]. Want me to do something different?"
## Step 2 — Quarterly estimated tax (if mode includes quarterly)
1. Pull YTD Profit & Loss from QuickBooks (Jan 1 through last completed quarter).
2. If QuickBooks is not connected, ask the user to paste net income or upload a CSV.
3. Ask: "How much have you already paid in estimated taxes this year?"
4. Calculate: SE tax, adjusted net income, federal income tax estimate (default 22% bracket), quarterly payment due.
5. State every assumption explicitly — bracket, business type, exclusions.
6. Deliver the formatted estimate with the due date for the current quarter.
## Step 3 — Year-end 1099 prep (if mode includes 1099)
1. Pull contractor/vendor payments from all connected sources: QuickBooks, PayPal, Stripe.
2. Aggregate by payee across sources. Flag likely duplicates for human review — never auto-merge.
3. Apply the $600 threshold. Flag near-threshold payees ($400–$599).
4. Check W-9 status in QuickBooks for each flagged payee.
5. Deliver the 1099-NEC candidate list with missing W-9 action items and the PayPal/Stripe 1099-K overlap note.
## Approval gates
- **Not tax advice.** State this in every output header.
- **State every assumption.** Bracket, business type, excluded deductions — give the accountant the levers.
- **Don't merge payees automatically.** Flag duplicates for human review.
- **Don't file anything.** Output is prep material only.
## Output
End with a next-steps checklist for the accountant: missing W-9s to collect, assumptions to verify, deadlines to hit.
