This year, we’re offering many new ways to automatically bring in your tax documents into TurboTax Online, including uploading PDFs of 1099-B and 1099-Composite forms.
Be sure to have the 2024 return file ending in .tax2024 on your computer so you can transfer it into the online version next year.
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. And you will have to pay first to see all the forms. All the Online versions do not have the same forms so you may need to upgrade to a higher version. Online Premium is the highest vesion and has all the same forms as the Desktop programs. You can only do 1 return per account. And pay for each account. You can use the same email for 5 accounts. Federal and state are separate fees.
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.
