EIN vs SSN and Taxes

Hi everyone,

Here's the scenario. I am a sole proprietor and have been using my SSN for filing Estimated Taxes this very first year. Although, I do not have any employees, I signed up and received a federal EIN and now use it with certain advertising firms.

My question is, say I earn a substantial amount of money from an advertiser (like Adsense) and my EIN (rather than my SSN) is on account with them, then how do I file/pay taxes using my EIN?

Now that I've sent two ES payments so far this year with my SSN rather than an EIN, what do I do for the rest of the year?

The above questions are starter questions as I have a lot of questions about this issue, and am looking for advice.

And one more thing, please use plain English to explain how these things work because, at the moment, I am not very "tax-talk linguistic".

Thanks!

well, I'm not gonna talk in a "tax-talk linguistic" manner 'coz I don't even have a clue about legal matters.

Sounds very serious

Sounds confused!
