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 find the “Alerts” section in the middle of the page. If you have any notifications, it is a good idea to look into them. 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 review. You will see any messages or letters received from the state there. 

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

Step 4: You will be directed to this page. 

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

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 might be thankful to learn that the Massachusetts return is pretty simple. Let’s dive in!

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

Starting with the top, in line 1 key in your gross sales that you made in Massachusetts for the related period. Lines 2-5 will all reduce your gross sales to get to your actual taxable sales. Read each line carefully to be sure that you enter your deductions and exemptions in the correct category. You may need to put values in more than one category. 

Notice that lines 5, 6, and 7 auto-populate based on what you put in lines 2 through 4. 

Let’s look at line 8. If you had any purchases on which you need to pay use tax, key in that number on line 8. Otherwise, proceed to line 11.

Line 11 may or may not apply to you. This line is a place to put a credit for pre-paid sales tax on tobacco products. If you do not sell tobacco products, this will likely not apply to you. 

Now you should see the tax due displayed on line 12. Take a second and double-check all of the numbers that you just entered. After that, select “Next” at the bottom of the page. 

Massachusetts gives you the option of submitting your return and payment at the same time. If you do not wish to do this, just go ahead and submit your return at this point. If you wish to submit your payment with the return, see the next section.
