Im sure it will be updated before the 4/15 due date, but "when"...nobody knows.

All my clients have been happy to pay by the April due date, it's due soon, may as well pay it.  But if they dont want to pay by 4/15, their choices are either  payment voucher they can mail, OR they (or even you) can go to the FTB Webpay website and schedule it there, CA makes it super easy to take your money!
