What everyone seems to forget
The USA tax code *itself* is an order of magnitude (or two) more complicated than the so-called "socialist" nation-states of Europe. If you have ANY kind of deduction, tax credit [1], non W-2 income [2], etc. then the IRS needs YOU to tell THEM exactly what and how much.
I wouldn't mind stuffing paper forms into the typewriter -- after working it all out in Excel or with a lined-paper pad and calculator, then paying extra for USPS Priority Mail with a tracking number -- but I have indeed leveraged paid software before to help me walk through WHICH forms I needed. In subsequent years, free software is fine [3] since I can follow simple instructions, as long as my situation doesn't drastically change. I especially like how software automatically chooses "standard" versus "itemized" deductions [4], and can show much exactly how much more I'm getting versus the other route.
[1] Credits may be refundable like tax payments, or non-refundable. You can get a tax credit just for having kids -- the Child Tax Credit, which requires an entire worksheet of its own to roll-off the credit for higher incomes.
[2] I don't even trust the IRS with 1099 forms, since some need to be "paired" with Schedule C -- working freelance for yourself is technically a self-owned business. Some people I know even file "doing business as" (d/b/a) forms with their state/county, get a separate Taxpayer Identification Number (TIN) from the IRS, and use that on the Schedule C so the IRS has a clearer delineation between personal and "business" income.
[3] I use Cash App Taxes (free federal AND state) and have since they were Credit Karma Tax. I didn't switch their very first year, so they could work out the bugs, but have been since. It's not a great solution if you don't know which forms, but fine if you're experienced, and you get the benefit of e-file. (Credit Karma got bought by our "friend" Intuit and had to spin off the tax service because conflict with TurboStax -- stacks of revenue for them, that is.)
[4] Itemized deductions WAS the winner, between mortgage interest, charitable giving, real estate tax, state income tax, even our annual value-based car registration fees, but thanks to the state/local tax limit imposed by some Congressional bozos and their clown-leader #45, I've gone standard the last few years. Who gets hit the hardest by such legal antics? Middle-class schmucks like me.
