My wife and I file pretty standard forms every year--no complicated deductions, only 2-3 W2s, maybe a couple 1099s and a 1098-E. For the first few years of our marriage, I did taxes by hand as a point of pride and enjoyed it (yeah, I know--most say yuck). Around 2006ish, I got a copy of TurboTax in a bundle with my first MacBook Pro and I've never looked back. It's absolutely worth it to me for $40 to me for the ease…
I live in Sweden. Yeah, that country. Not only do we have a bank issued digital identity our revenue service has a online system for doing your taxes and it takes less than 10 minutes.
If you buy/sell stocks using ISK and have a mortgage all of that is manage for you. You just review the numbers and sign of on it (using your digital identity). Then you get your returns.
The US tax system is perplexing to me.
