If you used the Desktop program before you may notice several differences and not like the online version. It has less features and no Forms Mode. The Online versions don't have all the same forms so you might have to upgrade to a higher Online version. You can only do 1 return per account. Your return is only saved online so be sure to save both the .tax2025 data file and the pdf file to your computer when you are done. In case you need to amend in the future or if you need a copy to get a loan or something. You might not be able to access your online return when you need a copy.
