SAN FRANCISCO -- Amazon.com Inc. shares edged up by 5 cents to $118.13 Friday, one day after The California state senate passed a bill requiring the online retailing giant to start charging sales tax on purchases in the state of California. The so-called "Amazon Tax" was included in a $5 billion state budget package. It has been estimated that taxes paid by Amazon, Overstock no teletrack payday loans.com Inc. and other online retailers would add $107 million annually to California's budget. Gov. Arnold Schwarzenegger said last year he would veto the measure and he is said to still be against the tax plan.
