ABERDEEN PROVING GROUND, Md. - The installation is offering free tax assistance to active duty troops, retirees and Family members through April 13.Services are offered at the center in the Office of the Staff Judge Advocate, Client Services Division, Bldg. 4305, 3rd Floor, Room 317.Installation Tax Coordinator Sandi Framarini called the service a substantial benefit, noting that the tax center prepared more than 1,300 returns and saved clients more than $191,000 in preparation fees last year."The biggest benefit is that they do not have to spend money getting their taxes prepared by a vendor off post," she said.In addition to the free tax preparation, CSD Chief Eric Fuestal said they also offer free electronic filing, a faster, more convenient and more secure method than paper filing.Electronic filing enables the taxpayer to receive refunds by check or direct deposit. The average return time is approximately three weeks for a check mailed and about 10 days for deposits made directly into a taxpayer's checking or savings account.Retired Soldier Scott Follett and wife Marsha Follett said that they appreciate APG's free tax services."We started coming here four years ago, after we moved to the area," said Marsha. "We think it's a great service, very accurate, and the cost is right."Several military units have unit tax advisors who prepare taxes for their active duty troops and Family members. Soldiers and Family members should determine if their unit provides this service before visiting the Client Services Division. Advisors will establish client eligibility and processing guidelines.Framarini said clients should bring all required documents that must be completed prior to receiving service, under the guidelines of Army Regulation 27-3 and the IRS Volunteer Income Tax Assistance Program.
