I see it's your first post here, so welcome to the community! Gabe gave some good advice, especially about checking your bill online; that's where you can go to see a breakdown of your monthly bill.
I pulled up your account to investigate and those two charges are for your payment when you first signed up and the subsequent taxes. New customers are charged initially for the service and equipment (if applicable), but they aren't charged for taxes. Tax fees are determined and charged after the installation so that's what the $3.03 is for.
You can see for yourself online: http://supportcenter.myhughesnet.com and follow the instructions here: http://hninfo.us/viewbill
To see the breakdown of your bill, open the bill and click the "Account Charges" link in the bottom left corner.
Hope that clears things up!
