A lot of US GDP is Rube Goldberg machines to skim off the economy. Intuit, Visa/Mastercard, private health insurance industry, etc. Lots of pushback to be expected as government fixes this (FedNow for payments, IRS improvements for taxes, healthcare reform, and so on). Onward.

It is how it works for most people in both the countries (on different continents ) I have worked in. Only people with high incomes or investment income or who are self employed or similar need to file their own taxes.

There are also cheap systems even for business returns - mine cost £12 for the company and I will use the free HMRC system for my personal return. It might be easier to use more sophisticated software, especially if your finances are complex.
