The advantage of tax software is not that it does the caculations for you, it is that it leads you through identifying what facts are important to take into consideration - eg. "Did you sell a house this year", "did you move for your job", "did you buy an electric vehicle" and so on.
Because we are interested in only the algorithm, not any implementation.
Software blurs the line between algorithm and implementation.
The problem people have with tax forms is not the calculations, it is understanding what has to go in the box in the first place. And, for a non-negligible part of the population, enough English literacy to read the form in the first place. Which is why volunteer tax preparation is a thing:
