According to the October 2017 newsletter of the California Franchise Tax Board, beginning in January 2018, California taxpayers will be able to e-file amended individual returns for tax year 2017 and later on a new Schedule X, California Explanation of Amended Return Changes. The Form 540X will be eliminated going forward, but you will still need to paper file Forms 540X to amend returns for prior tax years.
Californians Can e-File Amended Returns Starting in 2018
