<prompt> Human: Anyone waiting until the last minute to make a federal tax payment using the IRS website found they could not make a payment from 11:45 pm to Midnight on 4182017 - The tax deadline. The website said the site was down for planned maintenance but that you still were required to make your payment on time!!!  <response>: Maybe people shouldnt wait for the last 15 minutes of tax season to make a payment.
