How can I epay my state taxes?

You must pay your state tax due using the state’s preferred method of receiving payment.  For most states that will be by making a payment to the state’s own tax website, or by mailing a check or money order.

Is this new? I used to be able to pay CA taxes within TurboTax including last year. Very frustrating.

Yes. You can still schedule to have TurboTax deduct your California state tax due. However, you can’t schedule a payment date past April 18 even if you live in a zip code with an extended filing date due to a federal disaster declaration.

At this date, paying directly on the Franchise Tax Board website is a better option. Your payment may not be processed in time if you use TurboTax.
