No estimated tax penalty waiver relief available for California

In IRS Notice 2019-25, the IRS announced that is providing estimated tax underpayment penalty relief to taxpayers whose total withholding and estimated tax payments are 80% of more of their 2018 taxes. The relief was provided in recognition of the difficulty taxpayers had in adjusting to the numerous changes made by the TCJA. California is not providing similar relief because California has not conformed to most of the TCJA provisions so taxpayers’ California tax liability was not impacted.
