TurboTax is one of the few pieces of tax software meant for offline use, thus letting you keep your personal information from entering the permanent records of surveillance valley.

Just quickly looking at CashApp Tax, it appears it is an Android app that likely will want network access to function. If that meets your requirements, good for you. But it doesn't meet mine. I'd also rather use the same software year to year so that information is carried forward, rather than being subject to whichever way the startup winds blow.
