Pleasanton's main postoffice on Black Avenue will stay open late tonight to accept late tax returns at the drive-through lanes, with all returns deposited before midnight assured of an April 15 postmark.
Although the number of paper filers has decreased over the years as a result of electronic filing options, spokesman Augustine Ruiz said the Postal Service is still anticipating a high volume of tax filers at the post office.
"We have probably the world's most famous procrastinators," Ruiz said.
Ruiz is encouraging tax filers to drop off their mailings prior to the deadline to avoid congestion at the post office. Tax filers are also advised to get their mailings weighted properly and add the appropriate postage.
Besides Pleasanton's postoffice, other nearby facilities that are extending hours tomorrow night include Dublin, Livermore and San Ramon.
