I prepared a return back in February and the client requested that the balance of tax due on her return be withdrawn from her bank account. At that time, the date for the withdrawal was April 15. Now when I look at the letter for her return, it says the withdrawal will take place on May 17. Which is it?

I know that last year, all payments scheduled through the electronic filing of the return were still going to be taken on April 15 even though the filing and paying date had been changed to July 15. If the client wanted to change that, they they had to contact the IRS to cancel the payment and make other arrangements for paying the tax on the new due date. Is that the same for this year?
