Kentucky Income Taxes
Prepare and e-File your 2023 tax year Kentucky state tax return - resident, nonresident, or part-year resident returns - with your IRS return via eFile.com.
- State return only regulations*): Per IRS and Kentucky state tax agency regulation - not eFile.com - you can NOT just prepare and e-file a state return (with the exception of California) without also e-filing the IRS return on the same platform. If you have filed your federal return already, you can prepare a Kentucky state return on eFile.com and then download, print, and sign the return before you mail it in. See instructions on ONLY preparing a Kentucky and/or other state tax return.
- File your KY and IRS returns online so you do not have to worry about mailing anything.

* Due to IRS and state tax agency data sharing and validation requirements, you can only e-file a state income tax return while also e-filing a federal income tax return. This is not an eFile.com created policy, but a federally regulated one which all online tax filing websites have to adhere to. You can, however, prepare all 44 state income tax returns on eFile.com if you have already e-filed or filed your IRS return. View instructions on how you can ONLY prepare and file state income tax return(s).
