Reporting from Sacramento — Amazon.com Inc. upped the ante in its effort to overturn a new state law requiring all Internet sellers to collect sales taxes on purchases by California customers.
The Seattle online retailer reported late last week that it contributed $2.25 million to the More Jobs Not Taxes campaign to qualify a referendum for the June primary election ballot. The contribution brought the company's cumulative investment in the campaign to $5.25 million.
The referendum, if signed by at least 505,000 registered voters, would ask voters whether they want to uphold the law, which took effect July 1, or repeal it. Amazon is asking for a repeal, saying the California law is an unconstitutional interference with interstate commerce.
A spokesman for the Amazon-backed campaign, Ned Wigglesworth, declined to provide details of how the Amazon money is being spent. Those specifics will become available only when quarterly reports are filed Oct. 31 with the secretary of state.
