I hope not because I’ve been doing my US taxes on Linux for 15 years.

It’s probably a specific windows desktop app, probably TurboTax by intuit, the company that lobbies to make filing your taxes hard and to destroy any free simple government app to file taxes.

So, not sure why they’d complain about not being able to help shoot their foot off but we all have preferences. :shrug:

TurboTax has had a great browser-based version for over a decade now
