>That means filing your taxes just means going to Turbo tax and it importing your W2’s automatically

Whoa interesting, so everyone is using 3rd party company service, is it paid service or free, I've checked their website and cannot understand if it's free or not for this basic level you've mentioned.

In my country, if this was a thing, that you must pay some company to file your taxes, it would probably cause public meltdown and end of any current government :)

Here, basic level taxes are done by your employer for you, by law, for free. Because actually they don't do taxes, but they only report amount of tax advances, social security, healthcare paid by your employer, to state, (all 3 is required by law to be paid and you or your employer have big legal problems if not). And also variables for tax deduction and then "something like IRS" will just send you tax return into your account.

And for any other cases(if you have more sources of income, eg.: salary + self-employed / rent) you must do taxes yourself, website for helping you to file taxes, is managed by state agency, for free.

Or you pay some money to "tax specialist" to file your taxes for you and liability to file it right goes after them (something like accountant, but hired only for this one task)

US tax forms and rules are insanely complex compared to other highly developed nations. Lots of people use a commercial product called Turbo Tax to help them.
