finance-skills — US/Canada Tax & Accounting Skill Collection
Author: Simon-Pierre Boucher Contact: contact@spboucher.ai
Ten ultra-sharp skills covering US and Canadian taxation, small-business
accounting, financial statements, and legal tax optimization, following the
method in ../RESEARCH-SYNTHESIS.md and grounded
in web research with tax-year-2026 figures. All pass
python3 ../tools/validate_skills.py.
Collection-wide safety rules
Every skill in this collection enforces three limits:
- Educational help, not professional advice — complex situations are referred to a CPA/EA (US) or CPA (Canada).
- Figures rot — every dollar amount, rate, and deadline is stamped with its tax year and must be verified against irs.gov / canada.ca before use.
- Legal planning only — evasion (unreported income, fabricated deductions, falsified records) is out of scope and refused.

Shared conventions
- Description = WHAT + "Use when …" (literal phrases) + "Do not use for …"
- "Current figures (tax year 2026 — verify before use)" table with official source URLs in every applicable skill
- Every workflow ends with a validation step (checklist completeness, statements tie-out, both-scenarios math)
