The only thing worse than a public monopoly is where you have to navigate both a public monopoly, and a private monopoly, which is how taxes work in the US.
There is no monopoly on tax preparation in the US. It’s a highly competitive market. Dozens of companies sell online products to file, and thousands of individual providers are available too.
