    How to Sign in and File a Return on Indiana’s Website

    Let’s start with simple step-by-step instructions for logging on to the website in order to file and pay your sales tax return in Indiana. 

    Step 1: Follow this link, https://www.intax.in.gov/,  to come to this screen:


    Step 2: Sign in with your username and password.

    If you do not have a username and password, then your first step is getting that all setup. These login credentials are generally created when you submit registration paperwork for a sales tax permit.   

    After you sign in, you will see the page below.  Start by selecting “Business” on the left side of the screen.

    Step 3: You will be directed to the dashboard for the state.


    Think of this page as your home base. You can always come back to this page if you get lost. 

    Take a minute here to see and explore all of the tabs on the left side of the screen. You will see a “Messages” tab. Click into that, and see if you have any messages from the state. It is a good practice to get into the habit of checking this page every time you log in. 

    Once you feel that you have a good understanding of the dashboard, proceed by selecting the “Sales” link associated with your sales tax account. 

    You will now see a page with the previous filings (if you have any) displayed in the middle. The state of Indiana is a bit different for actually getting into the sales tax form. Most states have a clickable link on this page that shows you which period(s) are due. For Indiana, you actually have to navigate to the left side of the screen and find the “File” tab. Then select “File Form ST-103”.

    Step 4: You will be directed to this page. You will need to select the filing period end date and click “Next”.

    Step 5: Key in Sales Data

    If you have filed returns for other states, you will appreciate how simple and easy this Indiana return is. Enjoy it!

    You are now faced with a screen that looks something like this:

    As you can see, there are only four boxes where you can key in data. If you are filing a past-due return the “Penalty Due” and “Interest Due” boxes will also be available to edit. 

    In #1, enter in your total sales made in Indiana. In #2, put any exemptions or deductions that you had. If you have any use tax that you need to remit, you can do so in #6. You can use the calculator available to be sure you are remitting the correct amount. If you made any payments related to this period previously, enter the total dollar amount of those payment(s) in #9.

    Once you have done all of that and double-checked that the data is accurate, check the box at the bottom of the screen. Now click “Submit”. 

    That’s it! You have filed your Indiana sales and use tax return.
