how much of tax do I need to pay of my income from google adsense if I have an account registered as an individual publisher?

Google has published Google Adsense tax information at the following URL:

https://www.google.com/adsense/static/en...

"In the U.S., if you register as an individual, your income will be reported to the IRS on your social security number." So, you would treat the money from Adsense as your taxable income.
