Accessing Final MilTax Preparation and Filing Software – A Step-by-Step Process

STEP 1

Log in to your
Military OneSource account

You must have a Military OneSource account to use the free tax preparation and e-filing software.

If you already have an account
Click on the “LOG IN TO START” button on the MilTax Tax Services page. First, you may be directed to a Department of Defense consent page. After reading and clicking that you agree, click on the "Proceed to Login" button. You will be taken to a Military OneSource login page to continue. Enter your account credentials and click on the “LOGIN” button. Once logged in, you will be redirected to the MilTax software starting page and can proceed to Step 2.

If you do not have a Military OneSource account
Click on the “LOG IN TO START” button on the MilTax Tax Services page. First, you may be directed to a Department of Defense consent page. After reading and clicking that you agree, click on the “Proceed to Login” button. Go to the “Not registered yet?” section toward the bottom of the screen and click on the “Register Now” link.

Enter the information to register and submit to create your account. You will then need to check your email to verify your access. Click the link in the email you receive from Military OneSource to complete the registration process by filling out additional information and selecting your role. After completing this step, your account will be active. You may need to revisit the MilTax Tax Services page to log-in.

STEP 2

Confirm if you are filing at a VITA self-service kiosk.

Once you have logged into your Military OneSource account and are on the MilTax software starting page, you will need to confirm if you are using one of the Volunteer Information Tax Assistance, or VITA, self-service kiosks located at more than 100 military installations.

If you are not using a VITA self-service kiosk, select “no” to the question and click the “Continue to MilTax Software” button.

If you are using a VITA self-service kiosk, select “yes” to the question “are you preparing your return at a VITA location via a MilTax self-service kiosk?” You will be asked a few additional simple questions before you can click the “Continue to MilTax Software” button.

Once you have clicked “Continue to MilTax Software,” you will be alerted that you are leaving the Military OneSource site. You will be taken to the software provider’s tax filing site, and this will log you out of Military OneSource. Click “continue” to proceed to the final step, Step 3.

STEP 3

Log in or create an account with the MilTax software provider

Once you click “Continue to MilTax Software” on the MilTax software starting page, you will be taken to the tax preparation software provider’s website and asked to log in or create an account. The account is specific to this software provider and is different than your Military OneSource account.

If you have an existing MilTax account with the tax software provider from a previous year filing with MilTax, enter your login information.

If you do not have an existing MilTax account with the tax software provider from a previous year, click the green “Create Account” button to create one.

Once you have created your account and logged in with the tax software provider, you will be taken to the MilTax start screen to start your return.

STEP 4

For future access to the MilTax software, visit Military OneSource

To access the MilTax software in the future, you will need to return to the software start page and log in to your Military OneSource account before logging into your MilTax account on the software provider’s website.
