Military OneSource has launched its annual free tax filing software to help military members and their families, according to a press release from the Department of Defense.

The MilTax software is available through the Military OneSource website, and it walks military families through a variety of filing scenarios, said Erika Slaton, program analyst for the Defense Department’s Military OneSource program.

“Service members and their families have unique tax filing situations,” Slaton said. “There are frequent moves, deployments, or multi-state filings; there are a host of considerations that military members and their families face.”

The MilTax software allows users to submit one federal and up to three state tax returns at no cost, according to Slaton.

Tax experts are available to assist over the phone and on military installations at a Volunteer Income Tax Association location. Information on eligibility can be found on the Military OneSource website or by calling (800) 342-9647.
