I've used TaxAct for years, and generally it's worked well. I signed up early this year, so it is $17 for federal and it looks like $37 for state. Up until last year I really liked it, but they took FOREVER to put out their 1099 B CSV import software. I ended up inputting all of our transactions manually, which was not cool. If they're really behind again this year, I might switch in 2019, but I don't know where I'd go.
Our taxes did get more complicated last year with the addition of some distributions from a trust, but other than that, we don't have anything more difficult than two post-tax investment accounts and Lending Club (boo Lending Club).
