A few more questions if you don’t mind – 1) Do I still have to file quarterly? 2) Should I do a sole proprietorship, LLC, incorporate, etc?

When it comes to tax advice, you are best to discuss it with an accountant to determine what is the best decision for you. Even the state you live in can make a difference when it comes to these issues.

Sometime before the end of the year, Google AdSense will prompt you for tax information.

Please take a moment to read the AdSense terms:

and take note of section 12, which has much more detailed tax information and what Google will be requiring from you.
