New Section 19011.5 of the California Revenue & Taxation Code requires some taxpayers to make their tax payments using an electronic method which California calls “mandatory e-pay“.
There is a one percent penalty of the amount paid unless the failure to pay electronically was for reasonable cause and not willful neglect.
As a California tax attorney, I don’t know and the law remains unclear whether the penalty applies to those who are employees and who make regular tax payments by having employee withholding done by their employer.
In California, beginning January 1, 2009, personal income taxpayers whose tax liability is greater than $80,000 or who make an estimated tax or extension payment that exceeds $20,000 for taxable years beginning on or after January 1, 2009, must send the payment electronically. Once either of these conditions is met, all payments regardless of type, amount, or tax year must be remitted electronically by credit card, Electronic Funds Withdrawal (EFW), or web pay.
Taxpayers whose tax thresholds fall below the mandatory e-pay amounts may request to discontinue making electronic payments. In March 2009, the California Franchise Tax Board will provide a waiver form for taxpayers to file.
On December 1, the California Franchise Tax Board sent courtesy letters to taxpayers who made a payment in 2008 that could qualify them for mandatory e-pay. The letter informed these taxpayers of the law change, and that they may meet the mandatory e-pay threshold in 2009.
