Not sure if it was you or someone else who mentioned that you need windows because a tax program won’t run on linux? If so, there is a Linux version called Wubuntu I bekeive which runs wine in the background so folks can run windows programs on linux- not sure if thst would fit the bill for you or not? Might be worth trying it on a USB in love mode to see if it would work or not- it also looks a lot like windows too I guess- I’m gonna try it out soon.
thanks ... i might pick up a junk apple or w10 PC from a local recycler if H&R Block ever quits working on W7 ...
