@TAXHELLAGAIN thanks for this further explanation on the issue.
Intuit only supports the current version and last 3 years - since they introduced their license activation server in 2019 - older years' s/w should continue to run but you won't be able to activate it on a new computer for example so it's not reliable to depend on back versions of the s/w beyond that point (always export PDF with all forms and worksheets for your official record).
But seems if moving to this OS in 2028 when we would expect 2027 tax year plus 2026/5/4 to still fully work, then 2024 at least would not run, and the risk is if you need to file an amended return at that point which would be close to the 3 year deadline if filed April 2025. That's probably manageable, but gets worse every year that passes so the question is whether Intuit is doing anything about it in the 2025 version? We'll see in Oct/Nov what type of binary it is (I'm sure someone will purchase the early version and can confirm the binary type on this forum; I usually wait til January).
Meanwhile, the best way to voice concern on this issue and maybe get some direction is to write to the President - the folks complaining about end of support for Win10 and ItsDeductible have said they've been getting callbacks (fwiw) - I don't think you'll get any sort of answer or direction from Intuit on this sort of issue in this forum.
