Canadian taxes were/are simplified, APIs exist to login and fetch T4s and other services, and while it could be simplified further (particularly for corporate taxes and provincial incorporation, PEPPOL E-Invoicing and open banking legislation, etc.), the current state of things in Canada is pretty straightforward, including a relatively open program so developers can write and validate their independent tax software with the CRA. By comparison, when similar simplifications were attempted in the US, they generally failed due to lobbying efforts from Intuit and others. And my understanding is that in Canada, provinces try to harmonize more with the CRA, with the exception of Quebec primarily, while in the US states create many different tax situations, in part because there are more U.S. states than Canadian provinces.
