The instruction itself

5 sections, as written by the author

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:

  • Check the current date. If Oct–Jan, default to both. Otherwise default to quarterly.
  • 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)

  • Pull YTD Profit & Loss from QuickBooks (Jan 1 through last completed quarter).
  • If QuickBooks is not connected, ask the user to paste net income or upload a CSV.
  • Ask: "How much have you already paid in estimated taxes this year?"
  • Calculate: SE tax, adjusted net income, federal income tax estimate (default 22% bracket), quarterly payment due.
  • State every assumption explicitly — bracket, business type, exclusions.
  • Deliver the formatted estimate with the due date for the current quarter.

Step 3 — Year-end 1099 prep (if mode includes 1099)

  • Pull contractor/vendor payments from all connected sources: QuickBooks, PayPal, Stripe.
  • Aggregate by payee across sources. Flag likely duplicates for human review — never auto-merge.
  • Apply the $600 threshold. Flag near-threshold payees ($400–$599).
  • Check W-9 status in QuickBooks for each flagged payee.
  • 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.

How to use it

Copy the folder

Take anthropics/tax-prep from the repository into ~/.claude/skills for personal use, or into .claude/skills inside a project.

Check the name does not clash

The agent identifies a skill by the name field in its header. Two skills with the same name cannot sit side by side — one of them will be ignored.
