Is using a HOST necessary for tax collection with an EIN?

[Kapidouk]

Hello everyone! Is is a must to use HOST to help my account with taxes even though I have an EIN for my business I had just got on IRS online? The cost of HOST is about $280 for the service of autofill. I am new on this platform and I would like to know if it is a must to get HOST even though I already have an EIN I can use to fill for taxes at the end of the year. I would appreciate to get help on this topic.
