Skill · by Tallyfern

Four Agent Skills that help your AI assistant do Canadian sole-proprietor bookkeeping using CRA's rules, with live CRA rates from the free Tallyfern Rates MCP. - CRA mileage log: CRA trip fields, business-use %, the 3-month logbook test, live per-km rates. - T2125 expense sorting: turns bank, Etsy or Shopify CSVs into T2125 lines, applies the 50% meals limit, flags unclear rows. - GST/HST $30,000 check: CRA's small-supplier tests, and when you must register. - Year-end package: a tidy folder for your accountant or tax software. Works with Claude, Claude Code, Codex and Cursor. Single-buyer licence, no redistribution. Not tax advice. Designed by Tallyfern in Ontario with the help of AI tools. Every formula is tested by automated checks, and every CRA rate is tested against CRA's published figures before release.
