Guam - If you're one of those last minute tax filers, the Department of Revenue & Taxation is providing more convenient options for you to file. You can do so tomorrow at the Micronesia Mall or the Agana Shopping Center from 10am to 4 in the afternoon. Additionally the DRT drop box will be available until 12am Wednesday to meet the tax deadline. No payments will be accepted at the mall or shopping center sites. Payments however will at all Treasurer of Guam locations which include the Department of Administration office, DRT and the One Stop Center at the Department of Public Works.
