    How to Sign-in and File a Return on Idaho’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 Idaho. 

    Step 1: Follow this link,  https://idahotap.gentax.com/TAP/, 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 set up. These login credentials are generally created when you submit registration paperwork for a sales tax permit. 

    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 if there are any alerts that need your attention.  It is a good practice to get into the habit of checking this page thoroughly. You can also explore the tabs that run across the middle of the page if you would like. The “Correspondence” tab is a good one to look under. You will see any messages or letters received from the state here. 

    Once you feel that you have a good understanding of the dashboard, proceed by selecting the appropriate account. 

    Step 4: You will be directed to this page. 

    On this page, you should be able to see all of the periods that you have filed and the period that you actively need to file. You can also see the status of any of these previous returns filed. 

    If you have a return due, you will see the option to file the return to the right of the corresponding period. Select the “File Return” link.

    Step 5: Key in Sales Data

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

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

    First, answer the two questions at the top. Now let’s look at the “Total Sales” and “Less nontaxable sales” entries. Your total gross sales goes into the first box. Your exempt sales go into the second box. This client sells mostly on a marketplace, so that is why their nontaxable sales are so high. 

    The amount in box 3 should be the actual amount of sales on which you owe tax. If you have any items subject to use tax, enter that value into box 4. 

    Idaho uses a straight 6% tax rate at the state level. However, there are some cities and auditorium districts with local taxes in Idaho. You can read about those by following this link. Idaho is a little bit behind the curve. They still do not allow businesses to report local taxes on the state return. For that reason, you may need to file separately with some of these local jurisdictions. In particular, you will have to file separately if you are based in Idaho in one of these jurisdictions. 

    This can be very confusing, I know. However, this blog is about how to file an Idaho return. So let’s get back on topic.

    You should now see the total tax due to Idaho. If you collected more than the listed amount, you will need to enter the over-collection in the “Adjustments” line and put an explanation of “Excess Tax Collected”. 

    If you are filing this return on-time, you will not owe any penalties and interest. Once you are sure that all of the numbers look correct, click “Submit”. You should now be done with your sales tax return for Idaho. That was a pretty easy one, right?
