There is this year. Maybe not going forward. I tried to use it but it was easier to print the PDF and mail it. I also recall there were two different systems, DirectFile is one of the two, and it integrates with participating state tax systems.
In Belgium we have "tax on web" for more than 20 years and since a few years 90% of the things pre-filled for simple situations (mainly people without kids)
Same thing in France, and I believe most developed countries by now.
The situation is a bit different for business owners though, and most of them hire an accountant for this task. Doing it yourself can be risky as you may be committing tax fraud without realizing it before you get audited, or you may end up overpaying.
