Why this exists

Tax software treats the Income Tax Act as a black box and gives you numbers. A tax-aware agent treats it as queryable knowledge and gives you reasoning. The difference matters most when the right answer depends on facts the form doesn't ask for: a Holdco that may or may not earn its keep, an SR&ED claim whose proxy method changes the math, a cross-border payment whose treaty rate beats the statutory withholding.

The self-learning layer exists because tax law changes. Static rate tables go stale within a year. The dynamic rate overlay lets the agent absorb corrections without a code change.
