  • You don't have to complete your return all at once. By using the self-paced tax preparation software, you can create a secure user identification and password to save, close and return to your filing later.
  • You can file an amended return if you filed electronically. If you need to make changes after the Internal Revenue Service has accepted your return, you can file a Form 1040X to make changes. Use the tool available through the Military OneSource software. To prepare an amended return, click File an Amended Return under Tax Filing Resources on the Overview screen.
  • You can now include charitable deductions, mortgage interest and rental property in your tax return.
