I’ve worked on a few tools that need Canadian income tax brackets (federal and provincial) for calculations, projections, or estimators. This is not about sales tax or invoicing.

I was surprised there doesn’t seem to be a clean, structured, versioned source that’s easy to consume, especially once you factor in provincial differences and historical years.

When you need this kind of data, how do you usually handle it? Do you scrape the CRA site, hard-code values, rely on spreadsheets, or just avoid the problem entirely?

Genuinely curious if I’m missing an obvious solution.
