Happy linux desktop user here, I only need windows for turbotax once a year, so I will worry about this in Feb/Mar, anyone provides a cloud-based tax filing service?
Disclaimer: I have not used their online version so I don't know how well it works. I have been running their Windows version in a VM the last few years because I'm not wild about putting any more of my tax information "in the cloud" than I have to.
I would expect TurboTax to support online filing too, but did not see it on a quick search.
I've used H&R Block's online service for filing federal and state taxes for the past few years with no issues.
