The tax filing deadline is late this year because April 15 fell on a Saturday and Monday was a local holiday in Washington, DC. San Antonio’s postmaster said most post offices will not stay open late to accept those last minute returns. However, two locations will have late collections: Midnight at the General Mail Facility on Perrin Beitel Road and 10 p.m. at the Airport Post Office on John Saunders. © 2017 KENS-TV CONNECT TWEET LINKEDIN GOOGLE+ PINTEREST JOIN THE CONVERSATION To find out more about Facebook commenting please read the Conversation Guidelines and FAQs Leave a Comment TRENDING VIDEOS Woman stabbed twice in the leg at S.A. nightclub Families enjoy JBSA-Fort Sam Houston Fiesta & Fireworks Celebration KENS 5 Breaking Live Video Wagner HS teacher under fire for black history program Body found outside north-side Chick-fil-A 2017 Fiesta Wildflower Ride Home Depot shares tips for gardening this season Sailor faces charges of possession of child porn NIOSA: College Night Alamo 2 solar farm damaged by hail More Stories Amber Alert for 5-year-old girl at Hempstead park Apr 24, 2017, 4:36 a.m. Over 40 early voting sites open across Bexar County Apr 24, 2017, 6:03 a.m. Texas Cavaliers gear up for ‘Kaleidoscope' themed… Apr 24, 2017, 6:16 a.m.
