canada-hsa-calculator
TypeScript library and CLI for Canadian small-business health spending account tax savings, 2025 brackets.
What it does
Works out what a Canadian incorporated small business saves by paying medical expenses through a Health Spending Account rather than from after-tax income, from income, expenses and province, with 2025 federal and provincial brackets. Runs as an npm package or command-line tool in TypeScript, with JSON output. Ten provinces and territories are covered, not Quebec; the README gives no disclaimer.
Where it fits on the map
Not on the map: for individual taxpayers.
The map places maintained projects for a company tax department or a tax authority, without a demo or paid-service flag. Everything else stays on the list with its label.
